Ladies and gentlemen, thank you for standing by, and welcome to the Zai Lab, First Half 2020 Financial Results and Corporate Progress Update Conference Call. [Operator Instructions]. After the speakers' presentation, there will be a question-and-answer session. [Operator Instructions]. I would now like to hand the conference over to your first speaker today, Mr. Billy Cho, Chief Financial Officer of Zai Lab. Thank you, please go ahead, sir.
Billy Cho -- Chief Financial Officer
Thank you, operator. Good morning, and welcome to Zai Lab's First Half 2020 Financial Results and Corporate Update Conference Call. Earlier this morning, Zai Lab issued a press release providing the details of the Company's financial results for the six months ended June 30th, 2020, as well as recent corporate updates.
The press release is available in the Investor Relations section of the Company's corporate website at ir.zailaboratory.com. Today's call will be led by Dr. Samantha Du, Zai Lab's Founder, Chairperson and Chief Executive Officer. We will be joined by Tao Fu, President and Chief Operating Officer, who will provide more details on our pipeline, including upcoming milestones and commercial progress. Jonathan Wang, Head of the Business Development, will also be available to answer questions during the Q&A portion of the call.
And because each of us are dialed-in remotely, Samantha will take lead on majority of the questions and refer to relevant executives as needed. As a reminder, during today's call, Zai Lab will be making certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including our business plans and objectives and timing and success of our clinical trials, regulatory applications and commercial launches.
Such forward-looking statements are not guarantees of future performance, and therefore, you should not put undue reliance upon them. These statements are subject to numerous risks and uncertainties that could cause actual results to differ materially from what we expect. I refer you to our SEC filings for a discussion of risk factors that could cause our actual results to differ materially from those discussed today. At this time, it is my pleasure to turn the call over to Zai Lab's Founder, Chairperson and Chief Executive Officer, Dr. Samantha Du.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Thank you, Billy. Hello everyone, and thank you all for joining us. We have investors across the world, so I truly hope everyone and your loved ones are safe and healthy. Despite the headwinds brought on by the COVID-19 pandemic, we continue to build and define Zai Lab's leadership through strong execution. We have achieved many milestones since our last earnings call. We decided to provide you with a full update, and also outline what the future holds for us.
Our key accomplishments in 2020 to date includes two successful commercial launches in China, NMPA approvals for Optune, two highly strategic business development deals, three NDAs accepted with priority reviews, 15 CTAs approved and eight trials initiated across our broad pipeline which now includes 14 clinical stage assets. As you can see, we were able to overcome headwinds from the COVID-19 pandemic, launching both ZEJULA and Optune in under six weeks from regulatory approval and gaining immediate and strong support from the medical and payor communities given the number of patients with unmet medical needs.
ZEJULA was launched in China in late January and Optune was available to patients on June 30. Our clinical pipeline continues to expand with the addition of two highly differentiated late-stage assets: REGN1979, Repotrectinib. REGN1979 allowed Zai Lab to establish the hematological cancer therapeutic area with new exciting product base. Repotrectinib is highly synergistic with our existing pipeline, and further strengthens our long term strategic disease area strongholds. With a broad and differentiated pipeline, we remain confident that Zai Lab can become a leading global biopharma Company, leveraging our capabilities and network, to drive the next wave of innovation with transformative impact.
Over the next three years, we plan to have a steady stream approvals and commercial launches in Greater China, across multiple therapeutic areas. We established transformative partnerships and advanced our internally discovered global pipeline into the pivotal stage. Today, our portfolio consists of four USFDA approved assets with two approvals launched in China. 14 clinical stage assets, with nine in late stage development, two internal programs with global rights in the clinic, and over 25 clinical trials planned or ongoing across oncology, infectious and autoimmune diseases.
Looking to the end of 2020, and into the new year, we'll look to propel our strong momentum forward as we expect to execute our commercial strategies of ZEJULA and Optune in China. We start preparing for additional product launches, expedite the development of our late-stage assets for approval, deliver key clinical results. We continue to bring in potential best in class, or first-in-class assets through bolt-on and transformational business development opportunities.
We're proud of our global reputation as a biotech pioneer and the partner of choice in China, and remain very confident in our team, strategy, and platform, and continue to deliver exceptional execution and growth. This is why I believe that within next three years, Zai can reach our vision of becoming a leading global biopharma Company.
We also reached a significant milestone in 2020 by becoming a commercial stage company in Mainland China. Our commercial launches of both ZEJULA and Optune are under way and off to a great start. So, it's still early to comment on the launch trajectory for ZEJULA and Optune in China. We believe there is significant commercial opportunity for both assets.
Importantly, we are excited about the lifecycle management opportunities for both products and we are working closely with our partners, GSK and Novocure to aggressively expand into additional indications.
We also continue to strengthen and expand our human capital and global footprint. As of June 30th, 2020, we had 859 employees across seven offices globally with 366 and 377 employees, engaged in R&D and commercial activities, respectively. As one of the leading biotech, and the employee of choice, I am confident that we'll continue to attract top talent across all levels and disciplines to continue and grow with the firm.
We're pleased to say this is a very exciting time at Zai Lab, and our strategic mission is on a global scale. We believe we have the experience, the resources required to successfully reach our goals, and our execution track record speaks for itself. As always, we thank you for your continued interest and support and look forward to keeping you updated with all of our upcoming catalysts.
With that said, I would now like to turn the call over to our President and COO, Tao Fu. Tao?
Tao Fu -- President and Chief Operating Officer, Member of Board of Directors
Thank you, Samantha. As Samantha mentioned, 2020 year to date has been a productive and exciting period for Zai Lab across of a variety of fronts. We continue to build momentum within our commercial organization with the successful launches of ZEJULA and Optune. We executed two highly strategic business development deals establishing the new hematological cancer therapeutic area, and strengthening our solid tumor disease stronghold, with the addition of a potential best-in-class targeted therapy.
In addition, we expanded our China commercial organization and our global R&D teams through the recruitment of top level talent, and significantly strengthened our balance sheet to further enable Zai Lab to bring many more important therapies to patients. While our press release from this morning provides detailed updates across most of our programs, I'd like to focus my comments today on a few selected programs and near-term catalysts.
That said, we'll be happy to answer any questions during the Q&A session on any assets that are not covered in our prepared remarks. I'll start with Niraparib or ZEJULA, a PARP-inhibitor approved globally for the treatment of ovarian cancer, and in development for several other solid tumor indications. We believe ZEJULA is a potential best-in-class PARP-inhibitor, given it is the only PARP-inhibitor approved in the United States as monotherapy for all-comer patients in the first-line and recurrent maintenance treatment settings.
In addition, it has superior pharmacological properties including, once daily dosing, low drug-drug interactions and ability to cross the blood-brain barrier. As you know, ZEJULA was launched in China in January for second-line maintenance treatment of ovarian cancer patients, with over 800 hospitals covered at the time of launch.
As Samantha noted earlier, this commercial launch was done with incredible speed, with launch events held both onsite and online. Since the launch, ZEJULA has been included for regional reimbursement in one province and six cities. It has also been listed in 16 commercial health insurances and four provincial and municipal level customized commercial insurance, underscoring Zai Lab's execution capability in bringing important therapies to patients.
In addition to executing on our launch, Zai continues to focus on expanding the commercial opportunity for ZEJULA. Our sNDA for ZEJULA as a first-line maintenance treatment for ovarian cancer patients is currently under priority review by the NMPA. This submission was based on the results from the PRIMA study which demonstrated that women in both the HRD positive, and HRD negative subgroups experienced a clinically meaningful and statistically significant benefit. In May, Zai announced a positive topline results from the Phase III NORA study of ZEJULA as maintenance therapy for Chinese patients with platinum sensitive recurrent ovarian cancer.
The clinical data in Chinese patients confirms the compelling clinical profile of ZEJULA and were consistent with the results seen in the global NOVA study. Importantly, the NORA study demonstrated that an individualized starting dose regimen at 200 milligrams preserve the efficacy while improve the safety profile in Chinese patients, particularly with regard to the reduction of hematological toxicities including thrombocytopenia and anemia.
These results further underscore the promise of ZEJULA as a best-in-class ovarian cancer treatment. Looking ahead, our plan is to continue to develop ZEJULA and to bring this innovative medicine to as many patients who may benefit as possible, including in tumors beyond ovarian cancer.
Turning to Tumor Treating Fields. China NMPA has approved the Marketing Authorization Application for Optune in combination with Temozolomide for the treatment of patients with newly diagnosed GBM, and also as a monotherapy for the treatment of patients with recurrent GBM.
It is the first innovative treatment approved for GBM in China in over 15 years, and the first therapeutic medical device approved by the NMPA without the need of a clinical trial in China. Importantly, Tumor Treating Fields is recommended with Level 1 evidence for newly diagnosed GBM patients in China's Glioma Treatment Guidelines, recognizing its breakthrough treatment effect.
In addition, we recently launched Optune Lua for the treatment of malignant pleural mesothelioma in Hong Kong and expect to file MAA in China in the first half of 2021. While mesothelioma is not a large indication in China, the approval will be very synergistic and strategic for us given the next potential label expansion opportunity is in non-small cell lung cancer.
Speaking to that, Novocure expect to announce interim results from its LUNAR Phase III trial in non-small cell lung cancer in 2021. We also have an ongoing Phase 2 pilot clinical trial in first-line gastric cancer which is enrolling well. To give you a sense of market potential for these potential label expansions, the annual incidence rates in China for lung cancer and gastric cancer are over 733,000 and 679,000 diagnosed patients respectively, according to the 2015 National Cancer statistics. Now onto Ripretinib, our investigational KIT and PDGFR-alpha kinase switch control inhibitor licensed from Deciphera.
In May 2020, Deciphera, announced that FDA granted a full approval to Ripretinib or QINLOCK for the treatment of fourth line gastrointestinal stromal tumors or GIST in the all-comers setting. Ripretinib targets the broad spectrum of KIT and PDGFR-alpha mutations known to drive GIST. Since the FDA approval, NMPA has accepted our NDA filing with priority review. The magnitude of the unmet need for GIST patients in China is significant with over 30,000 Chinese patients diagnosed every year.
We believe NMPA granting priority review underscores the potential for Ripretinib to alter the treatment landscape for GIST patients, especially for those who are refractory to prior therapies and we look forward to working closely with the agency to advance this important therapy toward approval.
And finally, an update on our partnership with Regeneron and Turning Point Therapeutics respectively. REGN1979, an innovative CD20, CD3 bispecific antibody is Regeneron's most advanced oncology pipeline product discovered through their preparatory bispecific platform. It is being developed as a treatment for NHLs such as follicular lymphoma and diffuse large B-cell lymphoma in potentially registrational phase 2 trials. This strategic collaboration will support the enrollment of Chinese patients into Regeneron's global trials, accelerating the development and potential approval of this promising medicine.
We are thrilled to partner with Regeneron, a global leader in the research and development of innovative medicines and excited about the potential of REGN1979 as an off the shelf immuno-oncology treatment for NHL patients. More recently, Zai Lab was granted exclusive rights to develop and commercialize Repotrectinib, Turning Point's lead drug candidates in Greater China.
Repo is an investigational next generation tyrosine kinase inhibitor designed to effectively target ROS1 and NTRK mutations. In early clinical trials, it demonstrated potential best-in-class efficacy in both TKI-naive and TKI-pretreated patients.
Zai Lab anticipated opening additional sites for the Phase II registrational clinical studies. If approved, Repo has the potential to be the standard of care for ROS1 positive patients, about 2% to 3% of all advanced non-small cell lung cancer patients in China, a significant commercial opportunity.
With that, I will hand the call over to Billy Cho, our Chief Financial Officer, who will provide an overview of our financial highlights. Billy?
Billy Cho -- Chief Financial Officer
Thanks, Tao. I will now review our financial results for the six months ended June 30th, 2020. Revenues for the period were $19.2 million compared to $3.4 million over the same period in 2019. Revenues for the period were comprised of $13.8 million in sales of ZEJULA and $5.4 million in sales of Optune, respectively. Launched in January 2020, ZEJULA's revenue in mainland China was the main driver for the first half of 2020 given that Optune was commercially made available in China at the end of June.
R&D expenses were $102.0 million for the period, compared to $58.9 million for the same period in 2019. The increase in R&D expenses was primarily attributable to increased fees in connection with the upfront and milestone payments, ongoing and newly initiated late-stage clinical trials, payroll and payroll-related expenses from increased R&D headcount and expansion of research efforts to support internal development programs.
Selling, General & Administrative expenses were $42.5 million for the period compared to $29.5 million for the same period in 2019. The increase was primarily due to payroll and payroll-related expenses from increased commercial headcount and related costs as Zai Lab expanded its commercial operations in China.
For the six months ended June 30th, 2020, Zai Lab reported a net loss of $128.6 million, or a net loss per share attributable to common stockholders of $1.74, compared to a net loss of $83.3 million, or net loss per share attributable to common stockholders of $1.37, for the same period in 2019. As of June 30th, 2020, cash and cash equivalents, restricted cash and short-term investments totaled $464.1 million. We would now like to turn the call back over to the operator, so we can go ahead and take your questions. Operator?
Questions and Answers:
Operator
Thank you. Ladies and gentlemen, we will now begin the question-and-answer session. [Operator Instructions]. Our first question comes from the line of Yigal from Citigroup. Please ask your question.
Yigal Nochomovitz -- Citigroup -- Analyst
Hi, thanks very much for taking the question. I had a few questions on the ZEJULA launch. I know it's early days, but can you provide any early sense as to the market share that you have in second line ovarian cancer? And are you seeing early evidence of doctors switching patients from Lynparza to ZEJULA? And then could you comment at all to the extent to which you're seeing uptick in the regional hospitals in addition to the urban hospitals? And are you seeing any off-label sales of ZEJULA in first-line ovarian cancer?
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Thank you, Yigal. Good morning. And let me answer your last one first. First of all, we never do off-label sales. And secondly in the -- as earlier mentioned by myself, or Tao mentioned, even though it's still early for ZEJULA to see the launch trajectory, we are very, very optimistic about the -- how deeply we penetrate into the market, and also how the product being received by the patients, the medical community.
And as you probably know, we are still currently under self-pay, so with that self-pay we focus on -- very much on the KOLs, on the PIs and also we work with different groups and different regional governments. So we have very good coverage for the products. And even though it's only a six-month in the launch, we have seen a very deep penetration into the hospital sectors and there are some things we can give you, some color in terms of this -- we -- as you know, IMS only cover hospital penetration and for private pay, and usually we go -- you have to first go direct to patients and but even with that, and we have enjoyed four times of the hospital list compared to the competitor's first two quarters of launch.
And so I hope that give you some color on how we -- we have been doing.
Yigal Nochomovitz -- Citigroup -- Analyst
Okay. And -- [Speech Overlap].
Samantha Du -- Founder, Chairperson, Chief Executive Officer
You also -- I think you asked the question on -- you asked the question on different tiers of cities. And so far, we cover actually even though we first year we started with private-pay, we do cover many hospitals and with the listings [Phonetic] sales rate, we cover up somewhere around 800 hospitals.
Yigal Nochomovitz -- Citigroup -- Analyst
Okay. And any early evidence of switching from Lynparza to ZEJULA or that's not an information that you can glean at this point?
Samantha Du -- Founder, Chairperson, Chief Executive Officer
I think it's -- right now we -- it's too early to tell. But the fact we have some -- we have a very strong trajectory. And also, looking forward, we still have first line, we are -- where we will have only first line all-comers approval, and so we are very optimistic about the future.
Yigal Nochomovitz -- Citigroup -- Analyst
Okay. And then just, a question on the first line. So you have the priority review. When are you expecting that decision from the NMPA?
Samantha Du -- Founder, Chairperson, Chief Executive Officer
That's a good question. We received the priority review and soon after we filed, it was accepted. And as you know, China does not have a PDUFA date. But I can give you some color on our own experience. For second line ovarian cancer, we were able to get approval within a year and since we -- this product first line was affected in March and we're looking for of course and hoping everything is fair, as usual, which we haven't seen that much difference in terms of regulatory approvals, we are looking into the first half 2021. But again, I want to emphasize, there is no PDUFA date, this is to our best of knowledge.
Yigal Nochomovitz -- Citigroup -- Analyst
Okay, thank you. And then just very quickly on your proprietary program which -- pipeline, which we haven't talked about much. You said in the press release that you've started dosing in the Phase 1s very recently for 1201 and the 1102. Do you have any sense as to when we could see the first data from those two studies? Hello?
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Oh, sorry, I muted. Thank you, Yigal. And first of all, as you mentioned, we just started the patient recruitment this year, and as we have more clear, concrete data, we'll update to the market as appropriate.
Yigal Nochomovitz -- Citigroup -- Analyst
Okay. Thanks, Samantha. Thanks for taking the questions.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Thank you, Yigal.
Operator
Thank you. Our next question comes from the line of Anupam Rama from JP Morgan. Please ask your question.
Anupam Rama -- J.P. Morgan -- Analyst
Hi guys. Thanks so much for taking the question, and congrats on all the progress. For ZEJULA and Optune launch, can you give us a sense of what you're seeing in terms of unique prescribers for each of the products and what are you seeing in terms of repeat prescribing? Thanks so much.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
That's -- Yigal, first of all thanks -- Anupam, good morning, and that's a great question. And I will now let Tao to get -- to give you some topline answer on that.
Tao Fu -- President and Chief Operating Officer, Member of Board of Directors
Yeah, Anupam. Thanks for the question. I think it's still a little bit too early to really give you detailed information on new start versus repeat users. But as Samantha mentioned, we really feel ZEJULA launch has been off to a great start. We need to keep in mind this launch is really done in record speed from approval amid -- in the middle of a pandemic.
So the team really has done a great job in terms of implementing our launch programs, we have a few important metrics we track as Samantha indicated, everything is tracking very well. Overall, the product has been very well received by the treatment physicians. They really latch on to the superior pharmacological profiles of the product and the very compelling clinical data that we have both from the KOL global study, and as you know we recently also completed the NORA study which is a large China-only study demonstrating the product has very strong profile, preserving the efficacy and potential reduction of safety profiles, safety events with the individual starting dose in the Chinese patients.
So all these factors sort of play into, we believe a very strong launch and a great momentum.
Anupam Rama -- J.P. Morgan -- Analyst
Great. Thanks for taking the question.
Tao Fu -- President and Chief Operating Officer, Member of Board of Directors
Thank you.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
You're welcome.
Operator
Thank you. Our next question comes from the line of Jonathan Chang from SVB Leerink. Please go ahead.
Jonathan Chang -- SVB Leerink -- Analyst
Hi guys. Thanks for taking my questions and congrats on the progress. First question, can you give us a sense of how the first half sales broke down by Hong Kong versus Mainland China?
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Jonathan, good morning, and I first of all, let me say, we have a very good year, a good first half of Hong Kong. And, but since we have launched in China, I would say majority of the revenue actually contributed from Mainland China. And if you look at overall products, and first two quarters have -- gave us a very, very strong momentum. We currently do not have breakdowns to regional since we grew, we actually list by the whole product.
Jonathan Chang -- SVB Leerink -- Analyst
Got it. Thank you. And your second question, how should we be thinking about additional business development opportunities in the second half of the year and 2021? Would you expect these potential deals to focus on indications where you already have presence? Or could these be an indications outside your existing areas of focus? And would you have a bias toward certain platforms and approaches? Thank you.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
That is a great question Jonathan. You know, I think, I like the way you asked that, because I would then turn the table to Jonathan, our head of BD, so we can both, right, we all of us can make him work even harder, although I don't know how harder he can. Jonathan?
Jonathan Wang -- Senior Vice President, Head of Business Development
Thanks, Samantha, and thanks Jonathan for the question. Let me first say that at Zai we have really built a strong reputation over the last few years as a partner of choice for Western companies when it comes to this part of the world. And we also have a very robust business development pipeline currently in the backlog. And most of these are actually, by the way inbound interests from good, reputable US companies and a lot of them are the strategic objective for them to do a deal, is relooking for help, not only to access the Chinese market quickly, but also to help and accelerate the global development.
Now specifically in terms of the second half, I think we have had a very good first half and we have done two great strategic deals, one with Regeneron, one with Turning Point, both late stage assets, both arguably potentially best-in-class products in the categories. And we're working very hard to expedite those timelines in China and also working with them from a global development perspective.
So going forward, I think you can first of all expect us to always keep that same quality, a high bar that we have a hold to, that is globally best in class or first-in-class assets, obviously oncology, autoimmune and infectious diseases, are our priority areas. Especially oncology, where we have several indications in areas where we have building disease strongholds.
But I think we would also potentially not rule out going into other areas adjacencies, just like what we have done going from solid tumors into hemo with the Regeneron deal. We won't commit to a number in the second half of this year, but we're working very hard, and I think I'm sure we'll bring a lot more good deals in the very near future.
Jonathan Chang -- SVB Leerink -- Analyst
Got it. Thanks for taking the questions.
Operator
Thank you. Our next question comes from the line of Maury Raycroft from Jefferies. Please go ahead.
Maury Raycroft -- Jefferies -- Analyst
Hi, good morning, everyone, and congrats on the progress, and thanks for taking my questions. First one is just on the Optune MAA. So, I think prior guidance was for MAA filing in 2020. I guess is there any particular reason why you're now expecting that to happen in the first half of '21? Does it have anything to do with timing of Margetuximab LUNAR data, and can you talk more about what you're going to be looking for in the LUNAR data from '21?
Samantha Du -- Founder, Chairperson, Chief Executive Officer
First of all, I think Optune and the filing and for the second indication is under way, and also we already started bridging trials, and we actually think we are very well, making very good progress and we anticipate in first half next year, this is actually pretty consistent with our estimation. And of course you know that even though there is approval, and in terms of the -- like Jonathan mentioned, in terms of material impact, this is relatively small. But strategically, this is very important. This would be the first solid tumor and -- to solid tumor to be approved, and we remain very optimistic on our timeline.
Maury Raycroft -- Jefferies -- Analyst
Got it. That's helpful. And then -- and then for the anti-infected programs, I'm just wondering if there is a new found sense of urgency from China regulators to get these approved? And then for Durlobactam for the Phase 3, if you could talk more about the design of that study, design and timing for that Phase 3 studies.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
First of all, for Omadacycline, as you saw from our news release and that was on priority review, and in May, and I have to say, ever since China used open market priority review, this was the first one for anti-bacterial resistance drug has been put on priority review. And we, as we -- as China has no PDUFA date, it will be not wise for us to give you a projection. But again, we work with them closely on the approval, this is really important product, especially in China, the bacteria resistance that you mentioned is a very important area. It's a lot of unmet medical needs. And we just work closely with the agency, and we feel optimistic about it in this approval. And in terms of detailed timeline, when we get closer, we'll report to the market. The second question you asked about is the -- for the -- gram-negative [Phonetic] program, right? In terms of patient recruitment, we -- in China we have done a great job, and we have recruited the patients according to our current plans. And even though during the COVID, we haven't seen any disruption. But in terms of overall patient -- because this is a global trial and we have to work with our partner to give you more color on global timeline, and also on the trial design, we would -- because we're joining our partner Entasis on this program, we would prefer and we can rely on their disclosure.
Thank you, Maury.
Maury Raycroft -- Jefferies -- Analyst
Got it. Thank you very much for taking my questions.
Operator
Thank you. Our next question comes from the line of Seamus Fernandez from Guggenheim. Please go ahead.
Seamus Fernandez -- Guggenheim -- Analyst
Great, thanks for the question. So just a few here. I was hoping Samantha if you could just give us an update on data catalyst that you're most focused on. In particular, if you could just give us a sense of where you are most focused in your collaboration with MacroGenics. And then, as a separate question, can you just help us understand how you're thinking about the CD47 landscape in China, as you introduce your novel therapy? And any potential differentiating characteristics of that antibody that you think are worth noting. Thanks.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Sure. Thank you, Seamus for these excellent questions. And for the -- let me answer the last one CD47 first. And CD47, we have done extensive preclinical work. We see a clear differentiation from our internal work. Secondly, CD47 is -- will provide a lot of combo synergies with our existing pipeline. We understand there are seven other CD47 under development. Having said so, and is no one has been approved. And also while we -- at least we're still having, we are very confident based on what we know, and this can change as we get in more clinical information.
But we really believe with what we have seen so far, the differentiation justified, and also the combo opportunities justify for us to move this program forward. And I think when we get more clinical data, and also we close to the stage of doing more publication, I'm sure you will get the information. And so going back to the question on Margetuximab, and also our focus and our partner. I would leave that to Jonathan to cover.
Jonathan Wang -- Senior Vice President, Head of Business Development
Yeah, Seamus, I think the question on our focus with the MacroGenics collaboration, as you know, there were three assets that we licensed in that collaboration, obviously Margetuximab being the most advanced for that. And in that case, the gastric cancer trial, which we have started the global trial together with MacroGenics, I think that we hold a lot of promising with gastric cancer being such a large indication in China, and with the very early, but very promising data that they have in earlier trials, I think that is a focus for us. But in addition to that, as you saw, they disclosed data for their 013 trial at the PD-1 LAG-3 at the ASCO a couple of months ago. That data is very promising. Not only as monotherapy, but also in combination with Margetuximab, in various patient populations that normally don't respond to PD-1, such as triple-negative breast cancer, DLBCL, etc. We are seeing responses in PD-1, while expressing HER2 settings, we are seeing responses. So you know, it's very positive and although early, but I think that will also be a very important focus for us in our collaboration with MacroGenics.
Seamus Fernandez -- Guggenheim -- Analyst
Great. And maybe just as a follow-up question to the CD-47, we're also starting to see some CD-47 bispecifics emerge the PD1 CD-47 bispecifics. Any thoughts or in terms of your development capabilities, are bispecifics part of your own internal development pipeline? And then maybe, finally, I don't think anybody has asked about the sort of COVID and CoV-2 dynamics in China. Just wanted to get an update in terms of the -- on the ground experience as you deploy your sales reps in the field as well as just the ability to successfully recruit clinical studies, versus perhaps what we might be seeing in other markets that appear to be more affected than China. It would seem like that's an unique opportunity to continue to drive your research related collaboration. And with that, I'll jump back in the queue. Thanks so much.
Operator
Thank you. [Speech Overlap] Our next question comes from Ziyi Chen from Goldman Sachs. Please go ahead.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
I'm sorry, do you want me to answer Seamus question first?
Operator
Please go ahead.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Okay. So first of all, Seamus, and I understand that you have a good point about the bi-specific, but however I think this CD-47 program and we still -- we have with this potential combo opportunity, we will learn a lot from our existing program. And, at some stage we're in discovery and when we see it justified, and for doing the CD-47 PD1 bispecific, and we may consider -- we may -- let's say, we may talk about this program. But so far, we still focus on our CD-47 program by itself, and also potential combo opportunities. And we'll evolve as we move forward. And secondly, when you talk about COVID-19 and I think, and I appreciate your comments, and especially knowing how -- globally how it's been affected, and but in Zai Lab, we have been very, very fortunate and even though it's still too early to confirm, but we have always maintained our position, so we have very limited impact to our business. From patient recruitment, from commercial launches, from regulatory approvals, as you can see from our announcement, releases, announcements and -- the execution has been really, really done outstanding.
I gave that credit to the team and who has been able to work through this difficult time. And, but I have to also happily to report given the safety measures we have taken very aggressively, none of our employees have been infected and also the peoples we work closely with. In the Company, we have very clear procedure in place to deal with any situations should they occur.
And also in terms of the impact of clinical trials, we cannot speak to other companies. But we -- as I said earlier, we experienced very limited impact so far. In terms of the -- you know, the impact of the ZEJULA launch, we have to say we are funding the business to be quite defensive. We are not yet making changes to our 2020 revenue targets. We are still very optimistic, and we are still very confident on our team's deliverabilities, our team's execution, excellent execution, and of course this ZEJULA launch also helped by the fact that our major launch event will help, before the major break out for the ZEJULA, and especially we, in terms of the challenges over the first quarter and we have been taking immediate measures such as creating online physician, patient education and consulting programs, getting on reimbursement list at provincial, municipal levels, maximizing commercial insurances, and I think the commercial team and able to launch 23 days after the approval, it's a record by itself. And also it's really, really on a good start. So I hope I answered your question, Seamus, and really appreciate your time.
Operator
Thank you. Our next question comes from the line of Ziyi Chen from Goldman Sachs. Please go ahead.
Ziyi Chen -- Goldman Sachs -- Analyst
Thank you. This is Ziyi from Goldman. Congratulations on the second quarter. I actually got two questions. The first actually on ZEJULA, because we know that there's going to be an upcoming national reimbursement list negotiation in the second half, probably like October, November. So what is the strategy toward getting to a national reimbursement list for ZEJULA? And how should we think of the potential pricing cuts?
Or more like a trade-off about pricing and hospital penetration, particularly, just -- we launched the market for about six months. We're already penetrated into like 800 hospitals. That means without national reimbursement, we already got really deep penetration. So do you guys really need a -- in the first year, we're going to get into the national reimbursement to -- for a better hospital coverage or we can say for -- we can actually wait for another year? So that's my first question.
And second, I'm just trying to get a better sense of Optune, the commercial strategy or commercial model. Because this is probably the first of its kind like innovative medical devices. So if the patient is actually paying for the treatment or actually, they have to purchase the device itself. So, and also how those commercial health insurance actually helped the acceleration of adoption among the patients. I'm trying to get a better sense of that?
And a small follow-up is that we look at the PD-1 program, we see that --we start to initiate --put on non-small cell lung cancer into the potential clinical development strategy. So given the lung small cell -- non-small cell lung cancer in China in the PD-1 space have been really crowded, several near commercial approval, and there are potentially a few more who are also working on this indication. So why we're still -- or why Zai Lab is still trying to enter in this indication instead of looking at some of the other smaller, but a more differentiated indication? Thank you. Samantha?
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Oh, yeah. Thank you. I was muted. But first of all, thank you for your questions. In terms of ZEJULA, whether they need to be put on NRDL, and I have to say, as you said, the team has done a wonderful job for the first five months of launch. We already covered 800 to 900 hospitals with only 150 sales reps. However, we believe pulling on reimbursement dates will tremendously improve our coverage and penetrate further to not only top two tier cities, but the rest of the top --the third and fourth tiers. The volume will really gave us the overall revenue upside.
And in terms of -- so as you said, in November, China was -- and actually, when they started already asking for applications, and we definitely will be interested and welcome the opportunity to work with the agency to come up with a very reasonable and reimbursement price. We have good understanding, calculation of pharmaeconomics, and we also understand ZEJULA is the one and only for monotherapy first-line in China.
And also for ZEJULA, we are the only one as a category and for local -- from local company compared to our competitor. So we have many advantages, and we have many -- many opportunities to work with agencies to come up with a reasonable -- on pricing. And we really think we have a lot of room to talk to the agency. And --so our goal is to work with them. And we do not -- at least at this point, and I wouldn't say no. I would be very open minded and to come up with the right reimbursement strategy.
In terms of the question about the Optune; and as you said, this is the first only and Category 3 treatment option bring into China. And I have to say -- I give you a top line, first of all, patients are now buying the device. And I'll let Tao to elaborate further on that. And so Tao, you want to elaborate on that point?
Tao Fu -- President and Chief Operating Officer, Member of Board of Directors
Yeah, yeah. Thank you. Samantha. I just want to clarify your question is around our PD1 program and non-small cell lung cancer indication, right? I just want to clarify.
Ziyi Chen -- Goldman Sachs -- Analyst
Yeah. And also PD1.
Tao Fu -- President and Chief Operating Officer, Member of Board of Directors
Okay. So let me comment on the Optune first. So as you know, Optune is the first innovative treatment approved for GBM in China over the last 15 years. And it is also the first medical device that is approved by the NMPA without a need for a clinical trial. So the launch really is with considerable excitement about this product. We have very high awareness and support by the medical community. We believe there is a very, very strong sell-pay opportunity. And so far since launch, I think our launch has been off to a really good start. So that's probably the top line comment that I can make on Optune.
We have a very targeted strategy because the market for GBM is pretty concentrated in China, the top 250 hospitals really comprise of the majority of the market opportunity. So we have a very targeted strategy with our sales force, for our customers.
Billy Cho -- Chief Financial Officer
Yes. And Ziyi, if I may chime in here. There's a reason why we, as well as our strategic partner, Novocure, do not call this a device and say, a treatment or a therapeutic, because it really behaves that way at a practical level, at a clinical level. And I think that was also part of your question. So right now, the list price in China is US$19,000. It is a modest discount to the, I believe, a little bit over US$20,000 list price in the U.S. But nevertheless, it is a preposition as a premium therapeutic. Now post PAP, that number comes down, and it is going to be offered for GBM patients in Mainland China at a modest discount to the global net average price, which I believe is around US$11,000 based on the latest earnings release from our partner.
So with that payment comes in an all-inclusive -- that monthly payment comes in, so everything is included; so the device, the backup, the transistor rays, the hotline and the service element. So it really does behave in the way you are -- in the way you paid for it, in the way it's prescribed and administered. It does really behave in many ways like a therapeutic. So I hope that helps.
Ziyi Chen -- Goldman Sachs -- Analyst
Got it. Thank you, Billy.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Yeah. So coming back on the PD-1. And first of all, we participate -- we are in the process of participating in the global second line endometrial cancer. And together with our partner Incyte, we contribute the portion which is relevant for China's approval. In terms of the PD -- the non-small cell lung cancer, I agree with you, it's a very competitive landscape already. But having said so, and I think this is a huge market in China and globally. And with a very good PD-1 we have in terms of efficacy, safety and the way also by working with our partner -- and we only contribute the portion relevant to China's approval, we think it's very justified economically. And also the opportunity to bring patients with a very differentiated PD-1 and very much needed treatment option.
Ziyi Chen -- Goldman Sachs -- Analyst
Got it. Thank you so much, Samantha. And thank you so much for Tao and Billy as well. Thank you.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
You're welcome.

Thank you. Our next question comes from the line of Fei Zheng from Credit Suisse. Please go ahead.
Fei Zheng -- Credit Suisse -- Analyst
Hi. This is Fei. Thanks for taking my question. My first question is about the commercialization. Since we haven't breakdown the sales from Mainland China and Hong Kong, may I just ask for the Optune. Is that the sales mainly just from -- or sorry from the Hong Kong? And for ZEJULA, if the Hong Kong sales only grow at a slow -- relative slow rate, and the majority of the sales is also from Mainland China?
My second question is about some clinical readouts. Recently, I found that our competitors Lynparza has reviewed some overall survival data. I'm wondering do we have some similar overall survival data for ZEJULA? If not, when we are going to see those data?
And my third question is about my -- is about our internal pipeline, CD47. So I think Samantha mentioned that we have some differentiating factors. Is this mainly from the safety side or from the efficacy side? And also, once we complete the Phase 1 study, are we going to be looking for some license out opportunities to push the global trial for this product? That's my three questions. Thanks.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Thank you. Can I clarify your second question?
Fei Zheng -- Credit Suisse -- Analyst
Yeah, my second question is about ZEJULA because I have recently seen in the ASCO, the Lynparza reviewed the overall survival data in the BRCA-mutant settings. And they -- compared with the placebo, they have a very long extension of the overall survival. And I'm wondering, does ZEJULA have such a similar overall survival data benefit? If not, when we are going to see those data?
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Thank you for your question. Let me answer this first. First of all, and during GSK's global study for the PRIMA, they [Indecipherable] actually, we do have subgroups of gBRCA, HRD positive and negative. And in each category, we have achieved very amazing efficacy and also for -- particularly for gBRCA. And they -- I have -- Jonathan, you may want to comment more accurately about the month, the length?
Jonathan Wang -- Senior Vice President, Head of Business Development
Yeah. I think in the first-line setting, they obviously had very strong efficacy, not only in the BRCA positive, HRD positive and also in the HRD negative setting. Actually, I just can't remember the exact month for the BRCA positive, but it's comparable to -- definitely to be positives.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Yeah. I was under the impression anywhere around 21 months or 22 months, but I need to confirm that number. And definitely, we are -- if not better, we are at least in par with Lynparza. So that's my knowledge so far. To go back to your first question about ZEJULA, right launch we listed Hong Kong, China? Is that the question, right?
Fei Zheng -- Credit Suisse -- Analyst
Yeah.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
I think as I mentioned, we have done a great job in Hong Kong, continuously remain strong momentum. However, Hong Kong only has 7 million population versus 1.4 billion population in China. So with the launch of ZEJULA second-line in China, the next step will be first-line in China. China is -- Mainland China is definitely a growth driver. We have seen a very good start for the first six months, we remain very optimistic for the full year. And typically, even for companies, like you've mentioned, the competitors, people at base stage --we do not breakdown to that details. It's just I think confusing to the overall message. And we really look forward for a very strong growth for the second half. And your next question is PD-1, right? No, I'm sorry, it's CD47?
Fei Zheng -- Credit Suisse -- Analyst
Yes.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Yeah. And first of all, let me go back to say, as I mentioned, CD47 and from our internal and the pre-clinical data we do see, as I mentioned, differentiated profile. And from pre-clinical -- and specifically as you say it's efficacy or safety and we definitely see some -- because our ZL-1201, CD41 is a humanized IgG4 monoclonal antibody engineered to reduce effector function. So that gives us specifically -- and it has a very specific target. And so that data really give us the confidence in terms from the efficacy for going to clinicals.
But even we all know there's some safety concerns. And from our study, we also, so far, at least from preclinical level, we do see differentiation. But again, this is still very early in preclinical, just entering clinics with patients just started recruitment. We'll let you know when we have more information. And again, I also want to mention, this is not only differentiated, it's very optimistic based on the data we have, that's secondly, because the combo opportunities in the existing pipeline, we are -- we feel a strong justification for moving this into clinics.
Fei Zheng -- Credit Suisse -- Analyst
Okay, thanks. Thanks so much for answering my questions.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Sure. Thank you.
Operator
Mr. David Ng, your line is open. Please go ahead, from Macquarie.
David Ng -- Macquarie Group -- Analyst
Hi. Hi there, thank you for taking my question. I still have a couple of questions, I guess, surrounding the game plan of ZEJULA, especially in face of Lynparza also having the first-line maintenance approved late last year which kind of makes them eligible to enter another round of potential negotiation coming late this year.
So, you know, we don't have this specific figure, right. But when we -- if we look at the AstraZeneca first half presentation, it does shows that the sales in the so-called emerging market, which is, I think, mainly China, is already over $100 million during first half. So that's quite a big multiple versus ZEJULA. And I think that's also, we have to consider that that may be already factoring in the price cuts that they have implemented early this year to get into the NRDL.
So, in terms of the volume, we are still very far away from Lynparza. And if they have another first-line maintenance indication included later this year. And then after that, we may have [Indecipherable] in 2021, potentially off-label users competing in the same open market. So kind of like quite a fiercely competitive market entering 2021. Any particular comforts you can give us to show that you guys will be able to go against these two major players? So that's a question on ZEJULA.
Secondly, I think, on the question on Ripretinib, you guys are doing a bridging -- a small bridging study in China. But I guess your upcoming approval is not pending on that, right. I think, you guys already got the priority review, so that's like totally independent. There is no particular data that you need to wait for to satisfy the NMPA to get approval. That's question one.
I guess the second question is, besides we are also doing a second line, I guess, just a trial. And what's your thinking for that for China? Like would you go to push second line harder? Or were you still going to go launch fourth line first? And what kind of dynamics should we be expecting from that? And the final question for, I guess, for Billy, any guidance for full year R&D and SG&A expenses? And judging from the sales so far, what kind of stabilized gross margin for Zejula? Thank you.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Thanks. Good question. First of all let's say we [Indecipherable] product has been applied for third line gBRCA. So it's not second line or first line. So this is very differentiated. Second one, I do agree with you, you see a good revenue from Lynparza for the first half. We see that as a very welcome sign because they have been in the market and much two years ahead of us. So that means the market is going to be huge. And the fact we -- even though we just launched in China, first of all when we launched in Hong Kong within first year, they have -- more than 70% of the market share, even Lynparza was launched 18 months ahead of us.
Secondly, in China, even though we only launched last five months. And we are not on reimbursement to second line, but still for the first -- eight months, we have covered more than 800 to 900 -- from 800 to 900 hospitals. That is for the same period of the launch compared to our partner and our competitor, we have four times higher hospital coverage.
And this first year, even though we are on reimbursement, the second line only, we have done -- I think the team done fantastic job to work with private pay, to work with commercial insurance, to work with the original reimbursement. And I think we are just at the beginning. And again, let me highlight the differentiation, even on second line, based on Tao mentioned that we are -- we have, based on our ongoing study in Chinese patients, the data will be published in the next scientific committee meeting. And we have seen very unique differentiation, not only this is the -- we have high blood-brain penetration for metastatic patients.
Secondly, even in terms of the safety, we have seen very, very manageable and very -- especially for the concerns by thrombocytopenia and also the sales about anemia. We have very positive data. And we also adopt a dose based on the body weight. And we do not have to experience certain side effects causing by starting at a very high dose. And then you titrate down to 200 milligrams, you actually lost patients. And we do not see that. And of course, people say, once, if you consider even the pharmacokinetics, we have a much longer shelf life. We do once per day instead of BID. You may think that's not too important, but quite honestly, if you talk to the KPIs, this is a huge difference from compliance, from in real-world efficacy and safety because patients do have nausea when they take this drug during the day. And the compliance is going to be of course, once per day, compliance, so patients can take it before they go to bed either they can, some people, oncology patients always take multiple drugs.
But with once-per-day, if -- even you experience sleeping issues, you can take with half some melatonin, some Ambien. Patients do have benefit, do benefit from the efficacy and from the overall real-life experience. And lastly, and certainly last but not the least if you look at our China label, we don't go through SIP ANDA [Phonetic]. We go -- so with that, we have very clean drop drug interaction, especially for oncology patients. So second line, very differentiated. Even though we are underdog, we came two years later, we did not have -- for emerging markets 700 [Phonetic] million. To me, that's absolutely great for us. That paints a very good picture for us in terms of second line.
First line, you talked about gBRCA for our competitor get approved in China. But be mindful, gBRCA is only 12% to 15% of the population. We already did NDA accepted, put on the priority review. And I think with the timing -- and when it comes, I really think that will make fundamental changes in this landscape. And again, I always welcome to have more players in this space to open up the overall market. And we've been -- this team, this commercial team has launched six of the eight most pro PD-1, the most top-selling products in China. So we are very confident on our team.
And so the other question is, can I -- I am a little bit lost here. What's the other question you have?
David Ng -- Macquarie Group -- Analyst
Yeah. The other question is Ripretinib. Because your competitor basically failed fourth line, right? And ZEJULA does have a second line trial going on.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Yeah.
David Ng -- Macquarie Group -- Analyst
So it gives you some more space to strategize, like second line versus fourth line, what's the game plan in the next few years?
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Yeah. First of all, in -- for GIST population, other than the first line, the second and third-line right now actually do not need much -- do not as effective, right? So tremendous opportunities for fourth line especially for fourth line all-comer. And that's very important. That's what we already got NDA accepted on priority review, of course, we will definitely start with that, launch with that. But however, the second line and our partner has done a fantastic job to move forward to the second line indication. We also, like you said, we already have a -- in plan to recruit patients, and we gear up the -- we look forward to move to the second line.
For the fourth line, we also mentioned we already got acceptance priority review, whether our bridging trial matters or not. And I have to report to you our fourth line patient recruitment has gone really well. We have already generated many data. And whether it's needed or not, we'll work with agency and to bring this unmet medical needs to Chinese patients. We are very optimistic about this product whether its second line, fourth line, is very much needed in China. GIST is a big indication in China.
Jonathan Wang -- Senior Vice President, Head of Business Development
And David, I believe you had one more question for me, which was forward-looking guidance.
David Ng -- Macquarie Group -- Analyst
Yeah.
Jonathan Wang -- Senior Vice President, Head of Business Development
And I'll just quickly chime into that -- this portion up. But we do not yet provide forward-looking guidance, as, David, you already had mentioned in your opening question. But we are in a very fortunate position to, a, have a very strong balance sheet; and b, have all of our 14 programs progressing well. So we do intend at this juncture to continue to fund all of them as a part of our growth initiative. And within that is also SG&A as well as we prepare -- we have three NDAs already submitted with all prior reviews. So -- and you had a question on Ripretinib, and that will be our first gastric cancer or GIST program coming out to the marketplace.
So again, I think we're in a fortunate place where we are funding various growth initiatives. As far as your last question about gross margin on ZEJULA, and I think you were asking whether to use the current -- I think if you look at first half results, the gross margin was 74%. I would -- since that includes Optune as well, as well as the China Optune sales that launched at the very end of June, it combines various elements. So I would kind of not use that as a specific ZEJULA gross margin going forward.
You may want to wait out for additional results as we're still relatively -- not relatively, but we are still early in the ramp-up curves for both products.
David Ng -- Macquarie Group -- Analyst

Thank you. And our last question is from the line Wilfred Yuen of BOCI. Please go ahead.
Wilfred Yuen -- BOCI -- Analyst
Hi. Thank you for taking my questions, and congrats on the first half progress. Just two quick questions. First, for the CD25 bispecific and Ripretinib, actually, how many patients we are responsible for the global pivotal -- potentially pivotal trial as China data -- that the China regulator will accept it for our potential approval later on? The second question is on for -- can you share with us the second half commercialization organization plans that -- I understand that we now have 370 staff in the commercial team.
So I just would like to see what's the plan in the second half, given that we've got to gear up for the two products on the ground, Optune and ZEJULA. Thank you.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Sure. I think for -- sort of -- you were asking for throughput, right, and our contribution in the trials, right? And we will contribute what is necessary for the approvals in China. And detailed numbers, we're still working with partners.
And the other question about CD49 --CD47, how many -- we are still in Phase 1. So let's see. And the another... [Speech Overlap]
Wilfred Yuen -- BOCI -- Analyst
And the CD20 bispecific as well. So I understand the CD20, we are also contributing for their global trial, right?
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Right.
Wilfred Yuen -- BOCI -- Analyst
So my question is actually how many patients we will need to contribute in order to -- we can leverage the global trial for our NMPA approval later on?
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Yes. The answer is, we will incorporate enough to justify the China's approval. And also your last question, I'm sorry, I missed your last question. Could you repeat that?
Wilfred Yuen -- BOCI -- Analyst
Yes. Just can you share with us your plan on our commercialization team in the second half? I understand that we now have 770 staff in the commercialization.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
Right. Tao, you want to cover that?
Tao Fu -- President and Chief Operating Officer, Member of Board of Directors
Yes. Thank you for the question. So as you know, we currently have two sales teams, one focused on ZEJULA and one focused on Optune. So the ZEJULA sales team is about 150 reps covering about 800 hospitals to 900 hospitals. And the Optune sales team is about 50 people, covering about 250 hospitals. So we will be adding incrementally to this as the years go on to improve our coverage even more. And one other comment we have is we're also gearing up for Ripretinib launch. So starting in the second half of the year, we will -- starting to incremental put in place the Ripretinib sales force, too. That's going to be target more of the GI specialist. So those are the sort of the top line plan we have, yes.
Samantha Du -- Founder, Chairperson, Chief Executive Officer
And also, we are currently just to -- as a reminder, we are currently with as a private. So we are under -- not on NRDL. So when we need to be aggressive and after NRDL, we'll be changing as the commercial organization, we'll beef it up as appropriate.
Wilfred Yuen -- BOCI -- Analyst
