Prepared Remarks:

Operator

Good day, ladies and gentlemen, and welcome to the Exelixis fourth quarter and full year 2021 financial results conference call. My name is Towanda, and I will be your operator for today. As a reminder, this call is being recorded for replay purposes. I would now like to turn the call over to your host for today, Ms.

Susan Hubbard, executive vice president of public affairs and investor relations. You may begin.

Susan Hubbard -- Executive Vice President of Public Affairs and Investor Relations

Thank you, Towanda, and thank you all for joining us for the Exelixis fourth quarter 2021 and full year 2021 financial results conference call. Joining me on today's call are Mike Morrissey, our president and CEO; and Chris Senner, our chief financial officer; P.J. Haley, our executive vice president of commercial; Vicki Goodman, our chief medical officer; and Peter Lamb, our chief scientific officer, who will together review our progress for the fourth quarter 2021 ended December 31, 2021. During the call today, we will refer to financial measures not calculated according to generally accepted accounting principles.

Please refer to today's press release, which is posted on our website for an explanation of our reasons for using such non-GAAP measures, as well as tables deriving these measures from our GAAP results. During the course of this presentation, we will be making forward-looking statements regarding future events and the future performance of the company. This includes statements about possible developments regarding discovery, product development, regulatory, commercial, financial and strategic matters. Actual events or results could, of course, differ materially.

We refer you to the documents we file from time to time with the SEC, which under the heading Risk Factors, identify important factors that could cause actual results to differ materially from those expressed by the company verbally and in writing today, including, without limitation, risks and uncertainties related to product commercial success, market competition, regulatory review and approval processes, conducting clinical trials, compliance with applicable regulatory requirements, our dependence on collaboration partners and the level of cost associated with discovery, product development, business development and commercialization activities. And with that, I will turn the call over to Mike.

Mike Morrissey -- President and Chief Executive Officer

All right. Thank you, Susan, and thanks to everyone for joining us on the call today. Exelixis had a strong fourth quarter and full year 2021 across all components of our enterprise as we continue to grow the cabozantinib business and advance a diversified and growing pipeline of clinical and discovery programs. We'll keep our prepared remarks short today as we recently gave a detailed update to start 2022 at the J.P.

Morgan Healthcare Conference in January. Key topics we'll focus on today include: first, the CABOMETYX business continues to grow and fuel the investment in advancing our portfolio of next-generation therapies for oncology. CABOMETYX maintained its status as the leading TKI for RCC and surpassed the $1 billion net product revenue threshold in the U.S. in 2021 with a 45% year-over-year growth compared to 2020.

Second, we expect our development team, now led by Vicki Goodman, to grow in size, scope and stature in 2022 and beyond with the build-out of Exelixis' East complementing our extensive development, breadth and depth in Alameda. 2022 could be a year of significant portfolio growth with a focus on expanding potential indications for cabo with numerous expected top line results and advancing our important pipeline molecules XL092, XB002 and XL102, including the initiation of the pivotal trial program for XL092. Third and finally, our drug discovery network of internal and collaborative efforts across both small molecule and biologic platforms continues to advance at a rapid pace, with a selection of up to five new development candidates expected in 2022. Business development activities remain a core component of this strategy.

We expect to bring additional collaborations forward, including the potential for clinical assets where we have increased conviction from both a clinical and commercial perspective. With that, please see our press release issued an hour ago for our fourth quarter financial results and an extensive list of key corporate milestones achieved in the quarter. I'll now turn the call over to Chris, who will review our fourth quarter and full year 2021 financial results. Chris?

Chris Senner -- Chief Financial Officer

Thanks, Mike. For the fourth quarter of 2021, the company reported total revenues of $451.1 million, which included cabozantinib franchise net product revenues of $302.7 million. CABOMETYX net product revenues were $295.1 million, which included approximately $8 million in clinical trial sales. Our trade inventory weeks on hand remained relatively flat when compared to the third quarter of 2021.

Total revenues also included $148.5 million in collaboration revenues primarily from Ipsen, Takeda and Genentech. In the fourth quarter of 2021, Exelixis recorded a $100 million milestone payment due from Ipsen in connection with the achievement of $400 million in net sales in its related license territory over four consecutive quarters. Our total operating expenses for the fourth quarter of 2021 were $334.5 million, compared to $276.8 million in the third quarter of 2021. R&D expense was the primary driver of the increase in total operating expenses, which was primarily related to higher licensing expenses.

Provision for income taxes for the fourth quarter 2021 was $22.9 million, compared to $15.1 million for the third quarter of 2021. The company reported GAAP net income of $95.2 million or $0.29 per share on a fully diluted basis for the fourth quarter of 2021. The company also reported non-GAAP net income of $113.3 million or $0.35 per share on a fully diluted basis. Non-GAAP net income excludes the impact of approximately $18.2 million of stock-based compensation expense net of the related income tax effect.

Cash and investments for the quarter ended December 31, 2021, was approximately $1.9 billion. Turning to our full year 2022 financial guidance, which was previewed at the J.P. Morgan conference in January, we are now including total revenues guidance, which is expected to be in the range of $1.525 billion and $1.625 billion. The remaining full year 2022 financial guidance items can be found on Slide 12.

With that, I'll turn the call over to P.J.

P.J. Haley -- Executive Vice President of Commercial

Thank you, Chris. 2021 was a transformative year for the cabozantinib franchise, primarily driven by the approval of CABOMETYX in combination with nivolumab in first-line RCC in January of 2021. CABOMETYX reached a significant milestone in 2021, surpassing $1 billion of U.S. net product revenue.

The team continues to execute at a high level and this has resulted in CABOMETYX becoming the No. 1 prescribed TKI in RCC. Furthermore, CABOMETYX total prescriptions, or TRx, have now grown for five consecutive quarters. Additionally, the launch of CABOMETYX in differentiated thyroid cancer or DTC, which received FDA approval in September, is off to a strong start.

Taken together, the strength of the business and the momentum of 2021 position cabo well for growth in 2022. Prescription trends remained strong in Q4, both for NRx and TRx. Year-over-year growth in Q4 was 40% for NRx and 50% for TRx. As the launch progresses, the success of CABOMETYX in combination with nivolumab is changing the mix of patients on CABOMETYX in RCC.

Given the clinical data from the CheckMate 9ER study, we anticipate these first-line combination patients to receive therapy for approximately one and a half years or more, thus driving a significantly longer treatment duration for CABOMETYX. We are encouraged by the fact that in our data, we see a doubling of the amount of new patient starts at the 40-milligram dose in 2021 relative to 2020. This is further indication that the combination uptake in the first-line setting is robust. Turning to the TKI market basket of CABOMETYX, INLYTA, SUTENT, VOTRIENT and Lenvima, CABOMETYX TRx market share increased every quarter in 2021 with market share in the fourth quarter reaching 35%.

This growth is driven by combination usage in the first-line RCC setting. As we have discussed previously, the first-line RCC market is very competitive, and we are pleased with the performance of CABOMETYX in combination with nivolumab in this setting. Furthermore, we haven't seen significant competitive impact on our market share. Uptake in the first-line is broad across clinical risk groups and practice settings and prescriber experience to date has been positive.

We believe all of this taken together with the momentum in the business positions CABOMETYX for continued growth in 2022. Turning to other settings. We are pleased that the cabo second-line RCC business remained strong and was stable in Q4. In HCC, our market share was stable in Q4 and CABOMETYX continues to be the most prescribed TKI in the second-line setting for patients treated with immunotherapy in the first-line.

With regards to second-line DTC, we are pleased with the launch. And in Q4, we saw a strong trend of new patient starts in this indication which exceeded our expectations. There were previously no therapies approved for this patient population with significant unmet medical need, and we believe we are quickly becoming a standard of care in this setting. We are proud that this fifth indication for CABOMETYX adds to the body of data in the label and enables Exelixis to help more patients with severe cancer.

Looking beyond the five current U.S. indications for cabozantinib, we're planning for the numerous life cycle expansion opportunities as they begin to have top line data readouts in 2022. We look forward to having the opportunity, pending data and approval to bring CABOMETYX to more patients in need of therapies. Our team remains highly focused and motivated to compete every day to bring the benefit of CABOMETYX to all eligible patients as we continue to build the franchise and maximize potential.

And with that, I'll turn the call over to Vicki.

Vicki Goodman -- Chief Medical Officer

Thanks, P.J. Good afternoon. It's great to be here today, now a month and a half after I joined Exelixis as chief medical officer. I'd like to take a moment to introduce myself.

I am a medical oncologist and hematologist with nearly 18 years of experience in oncology drug development, both in government at the Food and Drug Administration and subsequently in industry. Prior to joining Exelixis in early January, I spent 15 years in roles with increasing responsibility at three global pharma companies, most recently at Merck, where I was Therapeutic Area Head for late-stage oncology. During my industry career, I have developed both small molecule drugs including kinase inhibitors and biologics, including immuno-oncology agents and antibody drug conjugates across all phases of drug development, from IND filings in Phase 1s to designing and implementing registrational studies leading to successful first approvals, as well as additional major indications. Today, I will cover our progress toward our organizational expansion to the East Coast, Exelixis' East, as well as progress on our pipeline and upcoming milestones for 2022.

As we announced in early January, we intend to develop a presence on the East Coast, specifically in the Philadelphia area, as we seek to access talent on both coasts to support our expanding development organization. I'm happy to report that we have now identified short-term move and ready office space in King of Prussia, Pennsylvania in the western suburbs of Philadelphia and a convenient and accessible location for much of the Greater Philadelphia and Central New Jersey biopharma talent base. We have also added the King of Prussia location as an option for the majority of open roles within the development and medical affairs organization and intend to initiate recruitment efforts immediately. Turning now to an update on our pipeline, beginning with our cabozantinib registrational trials.

We are on track for three Phase 1 readouts this year. COSMIC-313, evaluating cabozantinib in combination with nivolumab and ipilimumab in intermediate and poor-risk renal cell carcinoma is expected in the first half of the year. An interim primary endpoint readout for CONTACT-01 and readout of the progression-free survival primary endpoint for CONTACT-03 in combination with atezolizumab in PD-1 experienced non-small cell lung cancer and renal cell carcinoma, respectively, are expected in second half of 2022. Additionally, the final readout for overall survival in COSMIC-312 in hepatocellular carcinoma will occur later this quarter, and we anticipate regulatory filings shortly thereafter, if appropriate.

CONTACT-02, our Phase 3 study, in combination with atezolizumab in metastatic castrate-resistant prostate cancer is expected to complete enrollment this year. We continue to make progress on our pipeline molecules. XL092, our next-generation MET, AXL, MER and VEGFR tyrosine kinase inhibitor is being explored in combination with several checkpoint inhibitors and IO combinations and is progressing toward registrational studies. We recently initiated dosing on a nivolumab-based immuno-oncology combination study in genitourinary malignancies and continue to explore additional potential combination opportunities with novel agents.

Our first planned Phase 3 and third-line microsatellite stable colorectal cancer will be initiated in the second quarter of this year. Data supporting this study comes from two studies of cabozantinib in colorectal cancer, which were presented at ASCO GI in January, and demonstrated promising activity in comparison to historical controls of regorafenib, the current standard of care. XB002, our first antibody drug conjugate, which targets tissue factor, without interfering with the coagulation pathway in preclinical models is in dose escalation. Thus far, it has been well tolerated with no bleeding events observed.

A Phase 1 study of XL102, our oral CDK7 inhibitor, is expected to move into both single agent and combination expansion cohorts after completion of ongoing dose escalation and determination of the Phase 2 dose. Finally, XL114 has an approved IND and is currently in study initiation with first site activation expected this quarter. We expect to present Phase 1 clinical updates for XL092, XB002, and XL102 at medical conferences in the second half of this year. I'm excited to be working with the very talented Exelixis team as we continue to progress our pipeline.

Our current early clinical pipeline, as well as ongoing small molecule and biotherapeutic discovery efforts targeting novel mechanisms, positions us well to continue to address areas of unmet need to improve the lives of patients with cancer. With that, I'll turn it over to Peter for a discovery update.

Peter Lamb -- Chief Scientific Officer

Thank you, Vicki. I am pleased to provide a quick overview of the Exelixis preclinical pipeline. We have multiple programs ongoing, both internally and with our collaborators with over 10 programs in process with the aim of advancing up to five compounds into preclinical development in 2022. As you'll see in the pipeline slide, the preclinical pipeline is a balanced mix of small molecules and biotherapeutics, which is reflective of how we see the clinical pipeline evolving in the future.

As Vicki just commented, XB002 is advancing through Phase 1, and we're encouraged by both the preclinical and clinical profile we've seen to date. Tissue factor is broadly overexpressed in a wide variety of solid tumors and preclinically, we observed compelling efficacy in multiple PDX models. The PK data we've obtained so far from the Phase 1 trial also show high levels of intact ADC with low levels of free payload, indicating that it is a stable molecule. Hence, we believe that the underlying antibody is an excellent starting point for ADC development.

The recent deal that we did with Iconic allows us to develop additional ADCs based on the same antibody and we've started work to link it to additional payloads, particularly DNA damaging payloads such as T count. Ultimately, this will allow us to match different tissue factor targeting ADCs to different tumor types depending upon the sensitivity of each tumor type to different MOAs of the payload. A quick comment about XB010. This is our most recent development compound and is our first internally generated ADC that has been funded through our network of collaborators.

XB010 targets the oncofetal antigen 5T4, which is overexpressed in multiple solid tumors, including non-small cell lung, breast, head and neck and gastric carcinomas and utilizes Catalent's SMARTag site-specific conjugation technology and proprietary linker coupled to MMAE. This gives a homogeneous ADC with a controlled drug antibody ratio and a highly stable linker, which reduces free circulating payload. Our approach with XB010 is consistent with the philosophy behind XB002, which is to advance next-generation ADCs, incorporating contemporary ADC technologies directed against well-documented targets. XB010 has now moved into preclinical development and could yield an IND in 2023.

We're anticipating publishing preclinical data later this year at a major meeting or in a suitable journal. And with that, I'll turn the call back over to Mike.

Mike Morrissey -- President and Chief Executive Officer

All right. Thanks, Peter. As you heard on the call today, our team continued to execute across all facets of our business in the fourth quarter and full year 2021 with significant progress across our pipeline, clinical development and commercial activities. As we enter 2022, we're excited about the potential for the multiple growth drivers ahead of us, to move the business forward and most importantly, put Exelixis in a position to help many more cancer patients.

With our employees now back in the office working together side by side, I want to thank the Exelixis team for their individual and collective efforts in navigating the many significant challenges during the pandemic, including the recent Omicron surge. As I highlighted during my recent JPM presentation, we have the vision, drive and growing resources to become a multiproduct enterprise and to begin to expand our operations to serve cancer patients on a global scale with our planned Exelixis' East Coast presence as the first step in that journey. We look forward to updating you on our progress in the future. Thank you for your continued support and interest in Exelixis.

We're happy to now open the call for questions.

Questions & Answers:

Operator

Thank you. [Operator instructions] Our first question comes from the line of Jason Gerberry with Bank of America. Your line is open.

Chi Meng Fong -- Bank of America Merrill Lynch -- Analyst

Hi. Good evening, everyone. This is Chi on for Jason. Thanks for taking our questions.

Maybe just the first question is on COSMIC-313 on the data expected first half. How should investors think about the level of details from the top line results? Do you think 9ER top line result is a pretty good indicator for the level of initial disclosure Exelixis will provide in 313? And then a couple of follow-ups after that. Thanks.

Mike Morrissey -- President and Chief Executive Officer

Vicki, do you want to take that one?

Vicki Goodman -- Chief Medical Officer

Sure. Happy to. So I would anticipate that in terms of the top line results in a press release, it will be consistent with our prior practice, and then we will hold the full top line report for a medical meeting later this year.

Chi Meng Fong -- Bank of America Merrill Lynch -- Analyst

Got it. And on XB002 initial data second half of this year, the company has highlighted safety and bleeding as a potential differentiating feature for this drug. So I'm curious, do you believe the [Inaudible] in the second half, the initial disclosure will offer sufficient exposure or duration of treatment to fully characterize the -- that aspect of 002 profile?

Vicki Goodman -- Chief Medical Officer

Yes. So we're excited about the opportunity with XB002, in particular, because from a preclinical perspective, we've seen that it doesn't interfere of the binding of Tissue Factor to the coagulation pathway. And so we don't believe it will interfere with the extrinsic coagulation pathway. We remain in dose escalation at this point.

As I mentioned in my remarks, we have not yet seen any bleeding events. And we will plan, of course, to disclose the safety profile that we've seen when we presented at a medical meeting later this year.

Chi Meng Fong -- Bank of America Merrill Lynch -- Analyst

Got it. And just last one from me. Curious on the patent litigation front. Maybe what's the status on the Teva case given the recent litigation stay? Is this a situation where parties are looking to consolidate the new patents or what's going on with the MSN case.

Any color you can provide there to the extent you can, that would be helpful.

Mike Morrissey -- President and Chief Executive Officer

Yeah, it's Mike. Thanks for the question. I think Jason, and I'm sure you are involved here have been tracking the core docket pretty closely. You've written on that, others have.

So that's been fun to read. You guys have covered, I think, the facts per the docket pretty well. I really want to avoid opining on what's happening beyond what's in the docket, the facts that are there for all to see, and we'll continue to speak when appropriate as more information emerges from the court.

Chi Meng Fong -- Bank of America Merrill Lynch -- Analyst

Thank you so much.

Susan Hubbard -- Executive Vice President of Public Affairs and Investor Relations

Thank you, Chi.

Operator

Thank you. Our next question comes from the line of Michael Schmidt with Guggenheim. Your line is open.

Michael Schmidt -- Guggenheim Partners -- Analyst

Hey, guys, thanks for taking my questions. I just had one for P.J. and one for Peter. The first one is, nice to see the CABOMETYX market share among TKIs grow.

Can you break out at this point what your share is in first-line and in second-line RCC, respectively?

P.J. Haley -- Executive Vice President of Commercial

Yeah, this is P.J., Michael. Thanks for the question. So with regard to that, what I'll do is just kind of reiterate what we said previously. In terms of the second-line share starting there, we have majority of share certainly in the post-IO setting.

I think we said previously, that's around two thirds or so of the patients who received IO therapy in the first-line previously. And then for our first-line market share, we haven't disclosed specific numbers recently, and there's certainly some out there that you could look at. What I would say is we've had significant momentum. And as I kind of mentioned in the prepared remarks, that's really what's been driving our growth as the rest of the business has been stable.

So as you look at our TKI market share increasing over the year of 2021 from 30% to 35%, that's essentially almost all being driven by first-line uptake. So we're very pleased with that as the messaging and the data are resonating extremely well with oncologists, the balance of data in terms of our overall survival, our toxicity profile, as well as the quality of life data resonating well with physicians. And we're actually really excited. This weekend here in San Francisco, we've got the ASCO GU meeting and it's going to be live.

So really looking forward to our presence there, which will be significant and meeting with many of the KOLs in person, which will really be fantastic as we obviously haven't had as much opportunity to do that in the pandemic. So we're very pleased with our position. As I mentioned, I think we have really great momentum heading into 2022.

Michael Schmidt -- Guggenheim Partners -- Analyst

Yeah. And then -- yeah. Thank you. And then, I had a question perhaps for Peter.

This one is really around some of the early stage activities, specifically around the STORM Therapeutics collaboration. And I was just wondering if you could just comment what makes that particular company's technology exciting and any additional insights on the first target, I'd be curious to hear about that. Thank you.

Peter Lamb -- Chief Scientific Officer

Yeah, absolutely. I'd be happy to speak to that. Generally speaking, the STORM collaboration fits in with our overall approach and philosophy with certainly respect to small molecule discovery. Obviously, we have a very significant and growing internal small molecule discovery effort.

But we're happy to kind of complement that with outside partnerships and collaborations as makes sense in terms of providing complementary expertise or insight and still very much fits into that. The leading target, which took us to STORM is adenosine deaminase or ADAR1. I'd say, if you look at a lot of the publicly available CRISPR-based or SH based target discovery that's been done in oncology over the last couple of years, ADAR1 is a target that's come out as a very strong hit in a number of those screens. So to be colloquial, I would call it a very hot target in oncology right now.

That's probably up to about 30% of tumors or so that are probably dependent upon ongoing ADAR1 activity to help restrain what essentially becomes an interferon-mediated cell death. So that's some of the basic biology behind it. So it's been on our radar screen for a while is an interesting target. We're not experts in methyltransferases per se.

STORM's whole platform is a methyltransferase and kind of RNA epigenetics platform. And they've done a fair amount of work both on that platform generally, but also on ADAR1 specifically in terms of putting together the assays necessary to prosecute an effective lead optimization scheme, which as an aside, I will just say a nontrivial to put together. They've also made good progress on kind of enabling a structural biology approach to the target. So our view was it would very much jump start a program in the area to work with them rather than us trying to rebuild all that internally.

So it's early days for the collaboration. We're certainly excited to be in it and have it off and running. So I hope we'll be able to update on progress at some point in the future.

Michael Schmidt -- Guggenheim Partners -- Analyst

That's super interesting. Thank you. Appreciate it.

Operator

Thank you. Our next question comes from the line of Andy Hsieh with William Blair. Your line is open.

Andy Hsieh -- William Blair -- Analyst

Great. Thanks for taking my questions. So I have three, two really quick ones. So one is maybe for Chris, just from a modeling standpoint, how should we think about DTC contribution in the grand scheme of things? Second one, maybe P.J., I think sometimes you kind of talked about with these waves of times you see contraction normalization of the RCC market.

I'm just wondering what the current status that you've seen during the quarter? And also maybe your perspective maybe a little bit in Q1. And lastly maybe for Vicki. In terms of just thinking about XL092, and I think Mike has said this previously about potentially positioning that in HCC. And given the learnings from COSMIC-312, I'm just wondering if there is a way to set a minimum for hepatitis B-driven HCC and also and/or a maximum for hepatitis C-driven patients in the potentially future trial just to really maximize the probability of success? Thank you.

P.J. Haley -- Executive Vice President of Commercial

Great. Andy, thanks for the questions. This is P.J. I'll actually -- I'll take the first two.

So starting with DTC and kind of how we're thinking about that opportunity, as I mentioned in my prepared remarks, we're really pleased with the launch. And certainly, in Q4, we saw more patients starting therapy really than we anticipated, which is gratifying. It's an area of significant unmet need. And we believe we're off to a fast start toward becoming a standard of care in that setting.

The duration, if you look at the PFS in the 311 trial, it's around 11 months. So we believe there's a nice duration of therapy there. And as we're kind of thinking about that opportunity at a high level, we're thinking it's about $100 million, give or take, at peak. So that's kind of how we're thinking about DTC.

So with regards to your second question in terms of kind of how we're seeing the market. One way to view that is just looking at the prescription data from IQVIA over time. Obviously, in the pandemic, we saw some ebbs and flows there, but I think we've really stabilized over the second half of last year. We did see the market expand in terms of TKIs, I'd say the last few quarters of last year.

I would expect as IO/TKIs become more and more of a stable and frontline therapy, which they are becoming and combinations in general, really continue to grow in the first-line setting up to maybe close to 80% of patients receiving a combination therapy. But as more of those -- as those combinations of IO/TKI become more prevalent, I would just expect to see longer duration of therapy there that continues to drive overall growth of the TKI market that kind of goes in parallel to what we're talking about when we see the duration of therapy for 9ER continuing to provide growth in 2022 and potentially beyond for CABOMETYX. And I'll turn it over to Vicki for the third question.

Vicki Goodman -- Chief Medical Officer

Yes. Thank you. So we're excited about the opportunity for XL092 in many different tumor types, including HCC and other tumors where cabozantinib has demonstrated activity. To the point that you made, we have seen that different etiologies of liver disease and HCC may respond differently to different therapies, including checkpoint inhibitors, and VEGF directed therapies.

And we'll be taking all of those learnings into account as we build the development program for XL092 in hepatocellular carcinoma.

Andy Hsieh -- William Blair -- Analyst

Got it. That's very helpful. Thank you so much.

Susan Hubbard -- Executive Vice President of Public Affairs and Investor Relations

Yeah. Thanks, Andy.

Operator

Thank you. Our next question comes from the line of Jay Olson with Oppenheimer. Your line is open.

Jay Olson -- Oppenheimer and Company -- Analyst

Hey, congrats on the results, and thank you for taking the questions. Can you talk about how much runway you see for cabo plus nivo growth in the first-line RCC setting? And any feedback you're getting from clinicians on how cabo plus nivo compares to lenvatinib and -- plus pembro in a real-world setting? And then maybe just a follow-up on 092. With the initiation of a pivotal study in CRC, are you planning to initiate additional pivotal studies this year for 092? And how would you prioritize the various opportunities for 092 in your clinical development plans? Thank you.

P.J. Haley -- Executive Vice President of Commercial

OK. Thanks for the question. This is P.J. I'll take the first part there.

So I think in terms of -- I won't quantify growth other than to say, if you look at our guidance, we're anticipating robust growth for demand underlying that and in prescriptions in 2022 for CABOMETYX. And the reason I say that is really the majority of our growth, I mentioned DTC earlier, that's obviously some growth. But outside of that, the majority of that growth is due to first-line combination usage as we think about it of CABOMETYX with nivolumab. As I mentioned earlier, the duration of therapy will continue just a year on the market.

Now so that's going to continue to drive growth. Going forward, and we believe we have the opportunity to continue to get more and more new patients on therapy. Given our data and the story and kind of the strength of that resonating with physicians and the strong execution of our team, I will say that I think the experience of prescribers with the combination of the feedback we get, either through market research or advisory boards is very positive. They view the balance of efficacy and safety in their hands as a positive impression.

So I think that will also continue to augment our utilization going forward. And then I'll turn it over to Vicki for the second question.

Vicki Goodman -- Chief Medical Officer

Thanks, P.J. So we're looking to build a robust pivotal trial program for XL092. We're looking at various combination regimens, including novel mechanisms of action beyond the first few that we're evaluating currently in STELLAR-001 and 002. COSMIC-021, a signal finding study of cabozantinib will help inform our plans for 092.

As I mentioned earlier, they have a very similar kinase profile. So we believe that there's an opportunity to develop 092 in places where we've seen activity with cabozantinib, including from various cohorts of COSMIC-021. And so those cohorts, as they read out will help inform our plans for moving into pivotal trials with 092 beyond the CRC trial that we've already announced.

Jay Olson -- Oppenheimer and Company -- Analyst

OK. Great. Thank you very much.

Susan Hubbard -- Executive Vice President of Public Affairs and Investor Relations

Thanks, Jay.

Operator

Thank you. Our next question comes from the line of Mike King with H.C. Wainwright. Your line is open.

Mike King -- H.C. Wainwright and Company -- Analyst

Hey, guys, thanks for taking the question. I just wanted maybe to follow up on Jay's question about use in first-line RCC. Do you have more color on the proportion of cabo use that is in conjunction with a checkpoint? And I'm just curious if those are what I'd say, add-on therapy or the regimen starting with as a triple?

P.J. Haley -- Executive Vice President of Commercial

Yeah, Mike, this is P.J. So I guess what I would say is that in the first-line setting, previously, we've had the CABOSUN sort of data in our label, which was monotherapy. When we got approved for combination usage a little over a year ago with CABOMETYX in combination with nivolumab in the first-line, we really have seen the majority of utilization of CABOMETYX in the first-line shift to that doublet given the strength of the data and oncologists have been highly receptive of that. So really, that's what we're seeing primarily in the first-line setting with regards to CABOMETYX' utilization of the doublet.

I think as we think forward to 313, should that be a positive study in terms of cabo/nivo and ipi, I think that just will potentially expand the market opportunity for CABOMETYX in that first-line setting. There's certainly a lot of patients that do receive the combination of nivo ipi now in the first-line. So I think if there's an opportunity to add CABOMETYX with an appropriate risk benefit profile to that -- to those patients. We can get more and more patients should that study be positive.

So hopefully that helps frame that for you.

Mike King -- H.C. Wainwright and Company -- Analyst

Great. I appreciate that. And maybe one for Vicki. On CONTACT-01, I'm just wondering how we ought to think about the combo of cabo and atezo.

Hasn't been a development of anti-VEGF in non-small cell in a while. Just thinking about how that might provide some upside that really hasn't been widely discussed here.

Vicki Goodman -- Chief Medical Officer

Yes. Thank you for the question. So right, CONTACT-01 is a combination of cabozantinib with atezolizumab versus docetaxel, which remains a standard of care in non-small cell lung cancer after treatment with a checkpoint inhibitor plus or minus chemotherapy. It's really an underserved area with a lot of unmet need.

The primary endpoint here is overall survival, and we're expecting a readout of an interim analysis on overall survival sometime later this year. Again, docetaxel is an old therapy with not particularly good outcomes. And so we really believe this is an area of high unmet need and an opportunity to demonstrate further benefit for these patients. So we're looking forward to that readout later this year.

Mike King -- H.C. Wainwright and Company -- Analyst

Thanks. Much appreciated.

Susan Hubbard -- Executive Vice President of Public Affairs and Investor Relations

Thank you. Our next question comes from the line of Yaron Werber with Cowen. Your line is open.

Gabe Daoud -- Cowen and Company -- Analyst

Thanks very much. This is Gabe on for Yaron. So my questions are on the pipeline. First, what kind of data can we expect for the CDK7 program XL102, in the second half, specifically.

Will there be data from multiple cohorts -- multiple dose cohorts? Do you expect to see monotherapy activity with objective responses? And then for XL092 and CRC, Vicki touched on a little bit, but could you please discuss a little more detail maybe some of the early data that gives you confidence to go into the third-line pivotal study versus regorafenib. Thank you.

Vicki Goodman -- Chief Medical Officer

Sure. Thanks for the question. So I'll take the 102 first. Right now, we're in dose escalation with 102 and that's what we anticipate.

We anticipate the dose escalation cohorts will be presented at the medical conference sometime later this year. So these will still be fairly early data, and we will also look forward to additional clinical updates on that molecule in 2023. Regarding your question on the Phase 3 -- planned Phase 3 in colorectal cancer for 092. So this is a study in patients with third-line microsatellite stable metastatic colorectal cancer.

So they failed other therapies. We were acquiring documented RAS mutation status and basically randomizing them to either XL092 with atezolizumab or to regorafenib. The data that are supporting this study come from two studies that were presented at ASCO GI, as I mentioned earlier in my remarks. One was a cohort of COSMIC-021 and the other was an investigator-sponsored trial called the CAMILLA study.

So I can quickly run through some of those results for you. The COSMIC-021 colorectal cancer cohort response rate overall was 10%. But what we saw was a 25% response rate in patients who are RAS wild type. That was in combination with atezolizumab in patients who had no known MSI high or DMMR.

So a similar population to what we plan to study in 303. Likewise, in CAMILLA, the overall response rate in the overall population was 28%. But again, in RAS wild type, patients did better with a 50% response rate, and this was a durvalumab combo also in microsatellite stable patients. So as a result of these findings, we believe that the place we're most likely to see benefit is the wild-type patient population.

And so the primary overall survival endpoint will be focused on RAS wild type. However, we will also look at the population overall. And just maybe I'll add just for a point of reference, the typical regorafenib response rate is about 2%.

Gabe Daoud -- Cowen and Company -- Analyst

Thank you. Our next question comes from Akash Tewari with Jefferies. Your line is open.

Unknown speaker

This is Amy on for Akash. Just wanted to contextualize your 2022 cabo revenue guidance of $1.375 billion at midpoint with your prior expectations of cabo hitting a $1.5 billion run rate by the end of this year. Are you still comfortable with this run rate? Additionally, have you seen any seasonality in route cabo demand in channel inventory? And is there any color you can provide on real-world median duration of treatment for cabo in RCC? Thank you so much.

Chris Senner -- Chief Financial Officer

Yeah. Thanks for the question, Amy. So from an inventory perspective, I'll start with that one. I touched on it during the -- in my prepared remarks, the inventory stayed relatively flat Q3 versus Q4.

It actually was flat all year. But from a weeks on hand perspective, but it has been growing in line with demand throughout the year as demand increased. The first question is seasonality, but that's part of the inventory. The 1.5 -- sorry.

So on the $1.5 billion run rate, yeah, I mean, if you think about where we guided, it does get you into that range of getting to a run rate of $1.5 billion as we exit the year.

P.J. Haley -- Executive Vice President of Commercial

Great. And just -- sorry, this is P.J. just to kind of take the question. With regards to duration of therapy that we were -- our thoughts about that in CABOMETYX in combination in the first-line setting, it's -- we've been on the market for a year.

So in the trial, we see year and a half, give or take or more of PFS. So it's really early to be able to have a look back to see the significant duration we're expecting from 9ER. But as I mentioned, we believe that's a driver of significant growth for us. And I would just say that we're certainly pleased with what we're seeing thus far.

Unknown speaker

Great. Thank you so much.

Susan Hubbard -- Executive Vice President of Public Affairs and Investor Relations

Yeah. Thank you, Amy.

Thank you. Our next question comes from the line of Do Kim with Piper Sandler. Your line is open.

Do Kim -- Piper Sandler -- Analyst

Hi, thanks for taking my questions. First, on CONTACT-01. I was hoping you could frame for us the expected median survival for the control arm and maybe provide what your expectation or the hazard ratio that the study is powered to show.

Vicki Goodman -- Chief Medical Officer

Yes. So there really aren't great data in this setting of second-line. So as standard of care has changed, there isn't great data docetaxel is used because it was the second-line therapy following platinum therapy in the past and has continued to be a second-line therapy in patients who received generally speaking, an I/O and platinum combination. So I can speak to the fact that for patients who had lung cancer in the past, metastatic lung cancer, the median survivals were less than a year in the first-line and obviously substantially shorter than that in the second-line.

And we're shooting really for a substantial clinical effect here with respect to the atezo cabo combination. And so again, we'll see the first data from an interim analysis of overall survival later this year.

Do Kim -- Piper Sandler -- Analyst

OK. Thanks. And I have another question on seasonality for cabo sales. As we look to 2022, should we start seeing your typical first quarter seasonality due to reimbursement factors? Looking back at the sales for cabo, you seem to go through any potential impact.

Is this something we should start considering now? Or do you manage the gross to net to offset those factors?

Mike Morrissey -- President and Chief Executive Officer

Hey, Do, it's Mike. Probably not wise for us to be giving Q1 guidance in the middle of Q1. So stay tuned on the numbers when we have the Q1 call in May. We feel really good about how the brand is doing.

The -- again, timing with ASCO GU in the call are somewhat fortuitous, but we have a lot of support out there, both in the academic and community setting. And we feel like based on the data and based on the strong team that we have, we're going to continue to be able to educate physicians to the benefits of that combination but Q1, stay tuned.

Do Kim -- Piper Sandler -- Analyst

Understood. And last question for XL114, how are you thinking about the opportunity for MALT1 inhibitor? Is it primarily overcoming with T-cell lymphomas that have BTK inhibitor resistance? Or are you expecting to see the drug perform better than a BTK inhibitor in aggressive NHL?

Peter Lamb -- Chief Scientific Officer

Yeah. It's Peter, let me take that one. I think you correctly identified BTK resistance is a significant setting for 114. The mechanism of action is clearly downstream of BTK in terms of inhibiting activation of the car BCL MALT1 complex.

So that's certainly an area of interest. There are also subsets of lymphoma, B-cell lymphoma specifically, where BTK inhibitors are not active, where there are other mutations in the pathway, including in MALT1 itself, where we believe 114 could have activity where BTK inhibitors wouldn't. So those are two kind of early stage or initial stage opportunities that could be examined.

Do Kim -- Piper Sandler -- Analyst

Great. Thank you. Thanks for taking my question, and congrats on the quarter.

Susan Hubbard -- Executive Vice President of Public Affairs and Investor Relations

Thank you, Do.

Operator

Thank you. Our next question comes from the line of Peter Lawson with Barclays. Your line is open.

Peter Lawson -- Barclays -- Analyst

Great. Thank you. Thanks for taking the questions. On XL102 CDK7 inhibitor, what should we think about as success? And what should we be looking for in that data in the -- later this year?

Mike Morrissey -- President and Chief Executive Officer

Yeah. Peter, it's Mike. It's probably premature to give you that level of guidance. It's early in the year, and we'll have a pretty fulsome update when we do present that later in the year.

Peter, if you would like and can go through the basic biology there and give you a sense on how we think 102 is different. But again, it's probably early to start opining upon what we might see in our presentation months and months from now. Peter, do you want to say a few words?

Peter Lamb -- Chief Scientific Officer

Sure, yeah. I think if you look at the sort of history of CDK inhibitor development, we're a pretty interesting stage right now, one way and another people have been trying to advance CDK inhibitors for probably 20 years. If you look at the CDK family, they really fall, broadly speaking, into two buckets. There are those CDKs that are primarily involved in cell cycle regulation.

CDKs 1 and 2, CDK4/6, where obviously we have clinical proof of concept for that mechanism. And then CDK7 also clearly falls into that group. It's upstream of both CDK4/6 and 1/2 and very clearly has a role in controlling entry into various phases of the cell cycle. So there are a lot of interesting opportunities for the CDK7 inhibitor.

CDK4/6 inhibitor resistance being just one of those other tumor types, such as triple-negative breast or ovarian other possible opportunities. Then I would just add in addition to its CDK regulatory role, CDK7 also directly enhances transcription from both AR and ER. So then at least opportunities in combination in eRNA or dependent tumors as well. In terms of the profile of a CDK7 inhibitor, we obviously have our view of what's an ideal profile and XL102 fits that.

We think some of the important characteristics of first need to be highly selective and XL102 is. Second, I think this is a mechanism of action where you're really going to want to have maximal dosing flexibility to give you the best chance of optimizing therapeutic index. XL102 is a covalent inhibitor, but at least in preclinical models, cleared out of the plasma out of the circulation very rapidly. So you don't have a lot of it hanging around in the circulation, but you do have a prolonged pharmacodynamic duration of action based on the covalent mechanism.

Maybe I'll just finish by kind of segueing into a sort of related program. The second bucket of kind of CDKs are not that much involved in -- it felt like a regulation, but they are involved in regulating transcription and various subsets of genes, and that would include CDK9, but also CDK12 and 13. CDK 12, 13 is we have a program ongoing preclinically with Origin, nothing in the clinic yet for a CDK12 inhibitor. I think it's very interesting based on a lot of biology, but one part of which is that CDK12 is very much involved in regulating the transcription of DNA damage response genes, things like RAD51, BRCA and the like.

So there's also potential directions in which to take a CDK12 inhibitor. And hopefully, if things go well, we'll be advancing one into preclinical development in the not-too-distant future.

Peter Lawson -- Barclays -- Analyst

Got you. Thank you. And the CDK7 inhibitor, do you think it could have single-agent activity or really requires a combination?

Peter Lamb -- Chief Scientific Officer

Well, I can tell you, it's certainly preclinically, what we've seen is that we've seen robust single-agent activity in a number of different models. As Vicki commented with XL102, we're fairly early in the dose escalation at this point in time. So certainly, there's a rationale both as a single agent and in combination, but time will tell with respect to the development of clinical data.

Peter Lawson -- Barclays -- Analyst

Got you. Thank you. Just a final question around first-line HCC. The filing for 312, is that dependent upon OS being significant? And is HCC an area where 092 could move?

Vicki Goodman -- Chief Medical Officer

Yeah. So for 312, we'll be seeing the final OS analysis later this quarter. And we'll be evaluating the totality of the data and in consideration of the evolving treatment landscape before deciding whether or not it's appropriate to file. And yes, to answer your other question, we do see potential for 092 in hepatocellular carcinoma as we do in other tumor types where cabozantinib has demonstrated activity and we'll be thinking about development plans for 092 in that tumor as well.

Peter Lawson -- Barclays -- Analyst

Perfect. Thank you so much.

Susan Hubbard -- Executive Vice President of Public Affairs and Investor Relations

Thank you. Our next question comes from the line of Kennen MacKay with RBC Capital Markets. Your line is open.

Kennen MacKay -- RBC Capital Markets -- Analyst

Hey, thanks for taking the question. For Mike or maybe Vicki, how quickly do you think the COSMIC-313 data can be turned around into an sNDA, if it's successful? If that is in the first half, is that SBLI something that could happen later this year? And then maybe for P.J., with three Category 1 NCCN recommendations for frontline treatment of favorable risk ICC and four for poor and intermediate risk, what have been the drivers of physician preference for one regimen over another? And echoing on that, is there anything in the longitudinal CheckMate 9ER data at ASCO GU this weekend that you think could impact physician choice here? Thanks.

Mike Morrissey -- President and Chief Executive Officer

Vicki, do you want to take that one?

Vicki Goodman -- Chief Medical Officer

The 313?

Mike Morrissey -- President and Chief Executive Officer

Yes.

Vicki Goodman -- Chief Medical Officer

Yup, sure. Happy to. Right. So we are expecting to see the COSMIC-313 progression-free survival primary endpoint readout in the first half of this year.

We're obviously working with a partner on this study, Bristol-Myers Squibb, and we would be very motivated to work very closely with them and get that filing and as soon as possible, data-dependent.

P.J. Haley -- Executive Vice President of Commercial

Great. And it's P.J., Kennen. With regards to your question, in terms of physician preference and kind of what we're seeing in first-line, our utilization, as I've mentioned, is broad, and that really cuts across the clinical risk groups of favorable, intermediate and poor Corus disease. We're also seeing broad uptake, whether it's community or academic settings.

And I think that's really -- it's really driven by the balance of kind of efficacy, tolerability and quality of life data that we see in 9ER. And I think that's resonating really well with the prescribers and they're seeing good results in their patients. So I think that -- we're only a year into this. So I think the experience they're getting gives us further opportunity to continue to kind of grow in that perspective.

What I'll say with regards to the data this weekend is we're certainly pleased with it in terms of the longer follow-up. I think the -- it shows the durability of the data set overall. The complete response rate increasing to about 12%, certainly is a plus. And importantly, nothing to really change the perception of the tolerability profile.

So I think just more follow-up gives our story a little more power behind it. So we're very pleased with that. And as I mentioned, we're very optimistic toward the momentum of the business this year.

Susan Hubbard -- Executive Vice President of Public Affairs and Investor Relations

Thanks, Kennen.

Thank you. Our next question comes from the line of Jeff Hung with Morgan Stanley. Your line is open.

Jeff Hung -- Morgan Stanley -- Analyst

Thanks for taking the question. Most of my questions have been asked. So maybe one on partnerships since you mentioned that you expect to bring additional clinical partnerships forward. Can you talk about your strategy going forward in terms of collaborations for additional technologies? Is it more to be more opportunistic with new platforms and technologies? Or are there certain capabilities and technologies that you want to remain more focused on? Thanks.

Peter Lamb -- Chief Scientific Officer

Yeah. I mean as I kind of alluded to earlier, certainly on the discovery preclinical side, we've been -- we continue to look broadly both on the biotherapeutic and small molecule side, both for platforms that we think will be complementary to what we have access to now, and that may kind of broaden our ability to take on or tackle various targets or target classes. So we're happy to do those as they make sense for first of us and kind of partners. Of course, we continue to look at assets as well, individual assets there as well, particularly ones that are either late preclinical early clinical.

But I think as we've said a number of times before on that front, it has to be an asset that we have conviction behind in terms of being able to mount an effective clinical development campaign. And so basically, it's the right molecule, right time, right price kind of mantra that we're still taking to that.

Jeff Hung -- Morgan Stanley -- Analyst

Thank you.

Susan Hubbard -- Executive Vice President of Public Affairs and Investor Relations

Thank you. Our next question comes from the line of Chris Shibutani with Goldman Sachs. Your line is open.

Chris Shibutani -- Goldman Sachs -- Analyst

Great. Thank you for the questions. You described the first-line RCC marketplace as being a very competitive dynamic. Two questions, and it certainly has been where the regimens that have taken primacy have shifted.

The use of the IO doublet nivo in combination with ipi. What would you say is the outlook for what the share of use could be in the first-line setting over the coming years? I think you previously said it's about 20%, 25%. Is that to be stable? Is that likely to be any greater or less?

P.J. Haley -- Executive Vice President of Commercial

Yeah. Hey, Chris, it's P.J. It certainly is a competitive market, and that's what we've seen in the data with regards to nivo at BA. As far as predicting it, given, as you point out, the competitive nature of the market, I wouldn't endeavor to do that.

As I think about that though in terms of a potential positive 313 study, I think it just really gives us a lot of opportunity. To add TKI, which is a mainstay of RCC treatment for 15 years now to a potential IO doublet, which obviously has a solid place in the treatment regimen. So I think, yes, I think from more a dynamic perspective, that's how I think about things going forward.

Chris Shibutani -- Goldman Sachs -- Analyst

Got it. And then a question for Vicki perhaps. Vicki, I know you come from a lot of experience working at some of the leading players in oncology, Merck, Bristol, as well as at the FDA. We've been observing more broadly across the industry, some interesting decisions by the FDA, perhaps even over the last couple of weeks, where we're seeing this question of time lines for acceleration of approval be factored in with this question of unmet need.

And I'm asking this question in the context of how you're thinking about the development strategy for 092 as it follows in. Is that factoring into your thinking at all as you decide how to prioritize the next steps for 092? I know that you've talked about advancing into CRC, but there's other realms as well.

Vicki Goodman -- Chief Medical Officer

Yes. So as we're thinking about development plans, we're obviously looking at multiple factors. I think clinical unmet need is a big focus areas where we believe we have the opportunity to transform the care of patients with cancer. And of course, at the same time, as we're thinking about this, we are watching the regulatory landscape and thinking about how that may impact our development plans.

So we're closely watching the FDA trends, of course, taking that into account as we're developing our plans, realizing, of course, that we intend to develop our therapies globally, right? So we have to look at the regulatory climate around the world. But really, we're focused on areas where we believe that our experimental medicines may demonstrate benefit for patients with cancer.

Chris Shibutani -- Goldman Sachs -- Analyst

Got it. And then lastly, just one housekeeping in terms of the cabo revenue line. Just thinking back to over the past summer, where the clinical trial fails, and you also did a breakout within the 295 that you had that $8 million were for clinical trial sales. Can you give us a sense for what that your visibility into clinical trial sales in 2022? Is there anything in particular about quarters that can hit or miss or make things maybe unique one-off events? Thanks.

Chris Senner -- Chief Financial Officer

Yeah, Chris, it's Chris. So I'd say we don't have very good visibility. It's obviously up to those that are running the trial to place the purchase order with us. So generally, those timings will find out a few weeks, few months in advance.

And so we don't have good visibility throughout the year, but it's not included in our guidance number.

Chris Shibutani -- Goldman Sachs -- Analyst

Got it. And lastly, if I could squeeze one more in. Mike, congratulations. You had a new add to the board at the end of the year.

I was intrigued to see it was someone from outside of healthcare in the tech sector. Tell us about how you were thinking about overall composition of the board. You've had some folks who've been around for a very long time, Lance and Stelios and whatnot. And you made an addition here.

How should we be interpreting that thinking at the board level?

Mike Morrissey -- President and Chief Executive Officer

For sure. So we're very pleased to have Jacky Wright join the board from Microsoft. She is a just amazing resource to us from a broad IT and digital technology perspective. And as I'm sure we've talked about it at a high level previously, part of our corporate growth and part of our really expansion into digital is a key component to how we want to go, not only bicoastally, but also globally going forward.

So to have her engaged is just a tremendous resource for us. We're going to learn a lot from her and look forward to engaging with her on all aspects of both her view of how to really digitize healthcare but also then helping our business become much more efficient digitally as well.

Chris Shibutani -- Goldman Sachs -- Analyst

Great. Thank you for all the questions.

Susan Hubbard -- Executive Vice President of Public Affairs and Investor Relations

Sure. Thank you, Chris.

Operator

Thank you. [Operator instructions] Our next question comes from Stephen Willey with Stifel. Your line is open.

Stephen Willey -- Stifel Financial Corp -- Analyst

Yeah. Thanks for squeezing me in. Just a question on 092 and then actually, I just have a quick follow-up. But with respect to 092, so I know the STELLAR-303 study was obviously predicated on the notion that you had this surrogate data with cabo.

But I guess when I look at the GU development strategy with Bristol, we have nivo/cabo plus I think ipi/nivo/cabo data in both RCC and bladder. We have atezo/cabo data in prostate. Obviously, no IL-2 data yet, but just trying to better understand how the GU strategy is, I guess, going a bit deeper on the expansion cohort side as opposed to going into a Phase 3 like you did with STELLAR.

Mike Morrissey -- President and Chief Executive Officer

Vicki, you want to take a shot at that and maybe I can provide some color commentary afterwards.

Vicki Goodman -- Chief Medical Officer

Yeah, sure. Happy to, right. So we're looking at multiple potential combinations for XL092. I think as I said earlier, we may, in order to advance the program quickly, look also at data coming out of the COSMIC-021 trial, which is cabozantinib, right to move forward in a limited number of settings, the colorectal cancer being one of them.

And again, you may see additional Phase 3s launched from there down the road. But we believe that I-O checkpoint inhibitors and IO combos are important for the combination of 092 and that study STELLAR-002, which recently initiated enrollment, will be important to evaluating the potential of 092 in combination with those agents.

Mike Morrissey -- President and Chief Executive Officer

Yeah, maybe I can just add, Steve, that we're in the business of raising the bar in terms of standard of care for patients. Everything we do is focused on that. So less about generating [Inaudible] data, but it's more about going to the next level. And I think things like 313 are a good example of that, first company, first trial going against I/O, I/O as the control arm.

And certainly, with 092, we have the opportunity to do that across broad indications, across narrow indications as we develop that program. So I would look at the STELLAR-001, STELLAR-002 as the first wave really of that signal searching, signal validating type efforts while we're launching the pivotal trial program. We have a variety of other discussions ongoing with other combination partners, other combination owners, if you will, people with different I/O and other types of molecules that we and they want to combine with 092. So the program is advancing really in a multidimensional way.

I think what you're seeing here is just the beginning.

Stephen Willey -- Stifel Financial Corp -- Analyst

OK. That's helpful. And then just one quick follow-up on STELLAR. So I know CAMILLA was an investigator-sponsored trial.

But I know that study used a modified RECIST criteria. And I've seen it used before in liver cancer, but I guess I haven't seen it ease before in colorectal. And so just wondering if you guys know why a modified or assist response was used in this instance. Did patients all have liver mets or something? I'm just trying to figure that out.

Thanks.

Mike Morrissey -- President and Chief Executive Officer

Yeah. I don't know, Steve. Vicki, do you have anything you can say there?

Vicki Goodman -- Chief Medical Officer

Not really. I don't know specifically, but what I would say is that having the two data sets, including our own internal data set from COSMIC-021, both trending in the same direction in terms of better overall response rate than we would expect with historic controls. And although they're both single arm, the PFS and OS medians were also encouraging relative to what has been seen historically for regorafenib.

Stephen Willey -- Stifel Financial Corp -- Analyst

OK. Thanks for taking the questions.

Susan Hubbard -- Executive Vice President of Public Affairs and Investor Relations
