Jim Dentzer -- President and Chief Executive Officer
Thanks, Craig. Good afternoon, everyone, and welcome to Curis' first quarter 2022 earnings call. For those of you who haven't yet had the pleasure of meeting Craig, he recently joined the company as our vice president of investor relations and corporate communications, and we're delighted to have him on the team. Every day at Curis, we strive to develop the next generation of first-in-class cancer therapies that meaningfully improve and extend patients' lives.
The first quarter of 2022 has been a reminder that the path in clinical development is not always a straight line and that we need to collaborate with many different stakeholders along the way. We are encouraged by the knowledge that we have a drug that works as a single agent in exactly the places we expect it to. Further, the company is well positioned to manage through the dynamics of drug development, and we remain confident in our pipeline, our strategy, and our team. Let's start our update tonight with our lead asset, emavusertib, formerly known as CA-4948, our first-in-class program specifically designed to target IRAK4 and FLT3.
Emavusertib is currently being evaluated in three clinical studies. First, the TakeAim Leukemia study, a Phase I/II two study with monotherapy and combination arms for patients with relapsed or refractory acute myeloid leukemia, or AML, and high risk myelodysplastic syndrome, or MDS. Second, the TakeAim Lymphoma study, a Phase I/II study with ibrutinib for patients with relapsed or refractory NHL and other hematologic malignancies. And third, the Phase II LUCAS study, evaluating emavusertib in patients with lower risk MDS.
In January, we announced positive updated clinical data from the TakeAim Leukemia study showing early but compelling response rates in patients with spliceosome or FLT3 mutations. These results demonstrated both a manageable safety profile and improved anti-cancer activity compared with the current standard of care. Patients enrolling in this study are often in rough shape. They tend to be heavily pretreated and have an expected median survival of less than six months.
Given that baseline, we've been very encouraged by the study results to date. We'll be presenting the data highlighted in January at the ASCO and EHA medical conferences in June. Beyond that, we expect to report updated data from the monotherapy and combination portions of the study later this year. In April, the FDA asked us to pause the enrollment of new patients, placing partial clinical holds on both the TakeAim Leukemia and TakeAim Lymphoma trials, following Curis' report to the FDA of the death of a relapsed refractory AML patient, who after being on study drug for nine cycles, experienced, among several other conditions, rhabdomyolysis.
Patient safety is always our top priority. We're working with the FDA to provide additional data related to rhabdomyolysis and also our recommendation of 300 milligrams BID as the recommended Phase II dose, and we hope to resolve the partial hold as quickly as possible. We expect to provide updated guidance on the timing for discussions with FDA on a potential rapid registrational path for emavusertib after the partial clinical hold has been resolved and any potential impact on the study can be determined. Now let's turn to our study of emavusertib in B-cell cancers, the TakeAim Lymphoma study.
We expect to report initial data from this study at both ASCO and EHA in June, the same data at both meetings to address both the American and European audiences. This update will include new data on approximately a dozen patients, who have received emavusertib, who have received emavusertib in combination with ibrutinib in several types of NHL. As a reminder, Part A1 of the study, which is completed examined dose escalation in monotherapy. Part A2, in process now, is exploring the combination of emavusertib and ibrutinib.
This combination study is expected to enroll approximately 18 patients in a three plus three design with emavusertib doses starting at 200 and escalating to 300 milligrams BID and ibrutinib dosing will be whatever is appropriate for the patients respective NHL subtype. In this initial data set, we'll be looking to confirm that the combination of emavusertib and ibrutinib can be dosed safely without overlapping toxicities. And of course, we also hope to see signs of anti-cancer activity. Especially for patients relapsed or refractory to BTK inhibitors, signs of anti-cancer activity would be an early and encouraging proof of concept for the scientific literature, which suggests that targeting both the BCR and TLR pathways may prove more effective than targeting either pathway alone.
I'd also like to comment briefly on our collaboration studying emavusertib in patients with low risk MDS. This study is being led by Dr. Uwe Platzbecker, the co-chairman of the European Hematology Association's scientific working group on MDS. We hope to report data on this study later in 2022.
Being able to demonstrate safety and efficacy in these patients could represent a potential breakthrough in the MDS field. In March, a new potential opportunity for IRAK4 for inhibition was identified with the publication of pre-clinical data in the peer reviewed journal Gastroenterology, authored by our collaborators at the Washington University School of Medicine in Saint Louis. This manuscript examines the role of IRAK4 and the preclinical efficacy of emavusertib in combination with checkpoint immunotherapy in pancreatic ductal adenocarcinoma, a disease type with a very poor prognosis and in need of new therapeutic options. As we look ahead, we hope to build upon these results, working with the NCI and our other collaborators to identify additional new cancer targets, where emavusertib could address areas of high unmet need.
Moving to our second asset, CI-8993. This is the first-in-class monoclonal anti-VISTA antibody, which we are developing in collaboration with ImmuNext for the treatment of patients with relapsed or refractory solid tumors. CI-8993 is designed to antagonize the VISTA signaling pathway, thereby increasing T-cell mediated immune function. We believe CI-8993 is the most advanced anti-VISTA antibody currently in clinical development and has the potential to be a game changing cancer therapy affecting numerous cancer related immune mechanisms, many of which are not addressed by targeting PD1, CTLA4 or other immune checkpoints.
In January, we presented updated clinical data, highlighting an encouraging safety profile and early signs of CI-8993's potential to activate multiple anti-cancer immune mechanisms. We were additionally pleased with the PK profile, which exhibits saturation kinetics, suggesting the potential to overcome the anticipated zinc effect. Dose escalation has proceeded to the 0.6 milligrams per kilogram dose level and will continue until the recommended Phase II dose has been determined. We look forward to reporting expanded safety and tolerability data, along with initial PK, PD, and anti-cancer data from the trial in the second half of 2022.
In summary, we're pleased with the clinical results observed to death -- to date, and we expect to provide several updates later this year, including new clinical data in both IRAK4 and VISTA programs. In the meantime, we'll work with the FDA to resolve partial clinical holds as quickly as possible. As we have said to many of you in calls over the last few weeks. Clinical development is never a straight road.
We're fortunate to be working with a molecule with the unique and compelling profile of emavusertib. With that, I'll turn the call over to Bill to review our financial results for the quarter. Bill?
Bill Steinkrauss -- Chief Financial Officer and Chief Administrative Officer
Thank you, Jim. Curis continues to execute on its strategy from a position of financial strength. For the first quarter of 2022, Curis reported a net loss $16 million or $0.18 per share on both a basic and diluted basis, as compared to a net loss of $9.9 million or $0.11 per share on both a basic and diluted basis for the same period in 2021. Revenues for the first quarter of 2022 and 2021 were $2.1 million and $2.2 million, respectively.
Revenues for both periods represent royalty revenues recorded on Genentech and Roche's net sales of Erivedge. Operating expenses for the first quarter of 2022 were $17.2 million, as compared to $11 million for the same period in 2021. Operating expenses comprised the following. Cost of royalty revenues, which comprise amounts due to third-party university patent licensors in connection with royalties received on net sales of Erivedge, $0.1 million for the first quarter of 2022 and 2021.
Research and development expenses were $11.4 million for the first quarter of 2022, as compared to $6.8 million for the same period in 2021. The increase was primarily attributable to increased manufacturing costs for our programs and higher personnel costs as a result of additional headcount. General and administrative expenses were $5.7 million for the first quarter ended March 31, 2022, as compared to $4.1 million for the same period 2021. The increase in general and administrative expense is driven primarily by higher costs for personnel, stock-based compensation, professional consulting services, and insurance as compared to the prior year.
Net other expense for the first quarter of 2022 and 2021 was $1 million and $1.1 million, respectively. Net other expense primarily consisted of imputed interest expense related to royalty payments. As of March 31, 2022, Curis' cash, cash equivalents, and investments totaled $120.7 million, and there were approximately 91.6 million shares of common stock outstanding. First quarter cash burn was consistent with prior years of being higher than other quarters, driven by the timing of working capital changes.
We are in a strong cash position. We continue to expect that our existing cash and investments should enable us to maintain our planned operations into 2024. With that, I'd like to open the call for questions. Operator?
Questions & Answers:
Operator
[Operator instructions] Our first question today comes from Li Watsek from Cantor Fitzgerald. Please go ahead with your question.
Li Watsek -- Cantor Fitzgerald -- Analyst
Hey, thanks for the update and thanks for taking my questions. I guess first one, you mentioned that additional data are requested by the FDA. I just wonder if you can talk a little bit more if you need, I guess, additional preclinical data or clinical data and do you need to gather perhaps more clinical data, for instance, at lower doses to fully resolve this issue?
Bob Martell -- Head of R&D
Yeah. Let me address this. This is Bob Martel. We are, obviously, working closely with the FDA to answer their questions.
As you know, as Jim mentioned, they had requested a variety of components from us, one of which was a little bit more information to help us and them untangle the complex patient, who unfortunately passed away during treatment, after several eight months, actually, of treatment with this drug. Another is somewhat related to that, and that is our work to identify the appropriate dose going forward. So we've mentioned in the past, based on our pharmacodynamic work, our pharmacokinetics, safety and efficacy that we believe the 300 milligrams twice daily dose is our recommended dose will present those data to the FDA and have a discussion with them regarding that. Beyond that, the specifics of the data were we'll discuss that with the FDA and divulge more of that as we come to an agreement with them.
Li Watsek -- Cantor Fitzgerald -- Analyst
OK. Can I ask a follow up question, I guess. On the determination at the Phase II dose, I guess. Can you just talk about, I guess, what additional data points that FDA might need to see to justify, I guess, the dose selection? And I guess what gives you confidence that you can resolve this hold quickly?
Bob Martell -- Head of R&D
Yeah. So like I said, we've done a pretty thorough analysis. And in fact, as you know, we've evaluated a number of patients at 400 milligrams twice daily, 300 milligrams twice daily, as well as numerous other patients at lower dose levels. So part of the approach to identifying a recommended dose is understanding the exposure of each individual patient.
And so -- and this is typical for any drug in any any development. And more of what they're looking for these days is a good understanding of pharmacokinetic exposure bands. So we'll present those data to the agency to discuss that and justify our choice of 300 twice daily. In addition, we've carefully monitored the safety across all of these doses.
We believe that the safety at the 300 milligrams twice daily is a safe dose, and we'll present our data regarding that. As I mentioned earlier, we'll provide data to better untangle the complicated issues with this one particular patient, who unfortunately passed away on the study. Yeah, so those are some of the main things that we'll be looking at and presenting to them in a full report.
Li Watsek -- Cantor Fitzgerald -- Analyst
OK. Thank you very much.

Our next question comes from Soumit Roy from JonesResearch. Please go ahead with your question.
Soumit Roy -- JonesResearch -- Analyst
Hi, everyone. Thank you for taking the question. I wanted to just clarify, one thing is, have you already submitted all the necessary data set to FDA regarding this partial hold, or do we have a timeline on that?
Bob Martell -- Head of R&D
So again, we're working closely with the FDA. We haven't given specifics on the timing of that or whether or not we have done that yet. But as soon as we gain further information on our discussion with the agency, then we'll release that information.
Soumit Roy -- JonesResearch -- Analyst
OK. The June data in the -- on the animal front, that will be no new data. It will be probably finer details you will provide. Would you also include in media at ASCO? Would you also include details on this patient who died during the ASCO presentation?
Jim Dentzer -- President and Chief Executive Officer
Yeah. Thanks, Soumit. So I'll do the first one first. So the June data update, and there's going to be two updates, right.
There's going to be the leukemia and lymphoma. The leukemia is not an update. That's the January 6th data, which was, as you may remember, it was put out in a press release. This is now going to be in a peer reviewed forum.
So it's our opportunity to get that in front of the global physician network at both ASCO and EHA, American and European forums. Lymphoma, on the other hand, is new data. That's going to be roughly a dozen patients of emavusertib in combination with ibrutinib. And so I would point you to that.
And then lastly, you asked whether we'd take the opportunity at one of those two conferences to discuss more about the patient death. I'd say no. Our focus right now is having that dialog with FDA. And as Bob mentioned, the patient was on for a long period of time and we do have a lot of data related to that patient.
And I think the question is a fair one, but it's of course, a complicated one as well. And as we get resolution with the FDA on where they come out and where we can both get comfortable moving forward, that at that point, of course, we're happy to share all of the details. But because this is sort of an ongoing discussion and a very complicated discussion, we want to wait until we've got that resolved with FDA before we go public with the information.
Soumit Roy -- JonesResearch -- Analyst
Got it. Totally understandable. And one last one, the -- on the lymphoma front, the Part A2, would you present any data with 300 milligrams BID or do you know -- or can you disclose any patient being treated with 300 milligrams BID or pretty much all 200 milligram?
Jim Dentzer -- President and Chief Executive Officer
Yeah. As I said, I think we're going to wait for the disclosure of those data at that conference, but it is going to be new data, and I would encourage you to keep an eye out for it. We look forward to talking to you about it.
Soumit Roy -- JonesResearch -- Analyst
Thank you so much for taking my questions.
Jim Dentzer -- President and Chief Executive Officer
Thank you.

Our next question comes from Yale Jen from Laidlaw and Company. Please go ahead with your question.
Yale Jen -- Laidlaw and Company -- Analyst
Good afternoon and thanks for taking the questions. I've got two here. The first one is that with a partial clinical call for the other study combined, cow many patients are still eligible at this point to undergo studies on both a lymphoma and leukemia?
Bob Martell -- Head of R&D
Well, I want to make sure I understand your question. So we -- the partial clinical hold had us pause enrollment of new patients. All the patients, who were existing on study, who we felt were benefiting from the study are allowed to continue on. So it did not prevent those patients, who are ongoing, from continuing.
We haven't mentioned the specific number who are ongoing, but any patient who was continuing on would be able to remain on.
Jim Dentzer -- President and Chief Executive Officer
Yeah, the hold is simply keeping us from adding new patients to the study. So it really gets to the amount of patient data that we might have by year end. But the existing patients on study that are benefiting from the drug, of course, they can stay on, and we're still [Inaudible] them.
Yale Jen -- Laidlaw and Company -- Analyst
OK. Great. And maybe just two quick ones. Number one is that said for the pancreatic cancer study that -- is that allowed at this point or you're still being under the partial clinical hold until that being resolved to start enrollment?
Jim Dentzer -- President and Chief Executive Officer
Yes, so the [Inaudible] study. Yeah, that's not part of these clinical studies. But as I would say, our approach, you may remember when the leukemia study was originally put on hold, since it's the molecule, we're -- we were advising our partners across the studies, whoever is using the drug, that the spirit of the FDA clinical hold was don't enroll new patients. So of course, we would give you the same advice.
We'd say, look, let's let's wait till we get resolution with the FDA before we start enrolling new patients, whether it's in one of our existing clinical studies or whether it's in an IST. That's the same guidance we would give to anybody using emavusertib.
Yale Jen -- Laidlaw and Company -- Analyst
OK. Maybe the last one here is a little bit housekeeping that given that you might slow down the clinical development activity for sure, why should we anticipate the R&D expenses, at least for the next one or two quarters, be lower or trending slightly lower before taking up?
Jim Dentzer -- President and Chief Executive Officer
Yeah. Well, let me start that and then I'm going to hand over to Bill on that, Yale. So first, I'd say, obviously, the irony here is while you're on partial clinical hold, you're spending less, of course, than you otherwise would. And it really gets to the long term impact is, is how long are we going to be on clinical hold? And that's an unknown question, to be fair.
I mean we can look to the prior studies. As you know, in AML, there have been five other studies, five other companies, who have had their AML programs put on hold in the last three years. Four of those five were in the last year. All of those came off in roughly a one or two quarter time frame.
We don't know since, of course, every drug is different and every FDA conversation is different. We don't know that that definitely means that we're in that time frame. But if you use that as a proxy, you'd say it's a bump in the road between now and NDA. And it's not something that I would consider a material question from a cash burn perspective.
It's more a question of executing against the goals, especially when it -- when we think about how many patients we -- data we're going to be able to accumulate in this calendar year and, of course, in the rolling quarter view. Bill, would you like to comment a little more on potential impact?
Bill Steinkrauss -- Chief Financial Officer and Chief Administrative Officer
Yeah. I wouldn't want to necessarily give guidance but I think in terms of our approaches, we certainly want to spend money wisely. And while we are on hold will be considerate of that, but there's still a lot of work that, as you know, takes a long lead time so that if this is just a quarter of two delay, that we will be wanting to make sure that continues on. So I would expect us to be spending money wisely over the next few quarters and maybe there's some savings there, but I don't think there'll be a big impact to the trend unless the hold is to go longer than we expect.
Yale Jen -- Laidlaw and Company -- Analyst
OK. Great. Thanks for the details, and best of luck for you, guys.
Jim Dentzer -- President and Chief Executive Officer
Yeah. Thank you, Yale.

[Operator instructions] Our next question comes from Dane Leone from Raymond James. Please go ahead with your question.
Unknown speaker -- Raymond James -- Analyst
Hi, guys. This is Sean on for Dan. Thanks for taking the questions. Just one from us.
Trying to get an idea of what the scale and scope of the second half readouts for emavusertib would be. Obviously, you haven't said how many patients you've enrolled and in the studies, particularly in the [Inaudible] combos, but just trying to get an idea of maybe broadly how many or are you confident in the number of patients that are currently on study such that you could have a significant readout later in the year, irrespective of how long the clinical hold lasts? And then additionally, do you expect to read out any more data, say, on [Inaudible] recovery or efficacy in patients who are not FLT3 or [Inaudible] immune?
Jim Dentzer -- President and Chief Executive Officer
Yeah, that was a lot of question, so I'm going to try and hit them all. And if I miss one, Sean, please, please let me know and I'm happy to go back to it. So the scale and scope of what we're expecting for the year, obviously, is very dependent on on where we end up with the FDA in this discussion. But I would say in general, our milestones are very much the same as they were with the exception, of course, of the timing of meeting with the FDA to talk about the pivotal study.
And that one's just unclear. So let's go through those milestones again. First half of 2022, we're going to report initial data for emavusertib in combination with ibrutinib in NHL. That was already, of course, we started enrolling that a while back.
So we've already had those patients will have about a dozen patients of data to report out and that will be at ASCO and EHA as we announced today. Second, we will have updated data for emavusertib in AML and MDS imonotherapy later this year. Again, the number of patients is going to vary depending upon when we can restart the clinical trial and then how much time the patients have in the study and whether those data are mature enough for disclosure later this year. And then in the back half of the year, we've got two separate updates, initial efficacy data for CI-8993, the VISTA program and, of course, in the back half of the year the combination data of emavusertib with [Inaudible] in AML and MDS.
You may remember we started dosing patients in the back end of Q4 this past year. So we do have a handful of patients who are on drug before the clinical hold was put in place. And then hopefully, of course, if we can get the clinical hold lifted and we can start to enroll more patients in that study or in that regimen as well, we would look to give an update on those data. So a lot of data coming over the next six to nine months across both emavusertib and CI-8993.
And what?
Unknown speaker -- Raymond James -- Analyst
OK. Thank you.
Jim Dentzer -- President and Chief Executive Officer
Thank you.
