Operator

Hello, ladies and gentlemen. Thank you for standing by, and welcome to Zai Lab's Full Year 2023 Financial Results Conference Call. As a reminder, today's call is being recorded. It is now my pleasure to turn the floor over to Christine Cho, Senior Vice President of Investor Relations. Please go ahead.

Speaker 1

Thank you, operator. Good morning, good evening, and welcome to Zai Lab's full year 2023 earnings call. Today's call will be led by Doctor. Samantha Du, Zai Lab's Founder, CEO and Chairperson. She will be joined by Josh Smiley, President and Chief Operating Officer Doctor.

Speaker 1

Rafael Mato, President and Head of Global Oncology Research and Development Doctor. Hal Reinhart, President and Head of Global Development, Neuroscience, Autoimmune and Infectious Diseases and Doctor. Yajing Chen, Chief Financial Officer. Jonathan Wang, our Chief Business Officer, will also be available to answer questions during the Q and A portion of the call. As a reminder, during today's call, we will be making certain forward looking statements based on our current expectations.

Speaker 1

These statements are subject to numerous risks and uncertainties that may cause actual results to differ materially from what we expect due to a variety of factors, including those discussed in our SEC filings. We will also refer to product revenue growth rates on a constant exchange rate basis, which is a non GAAP financial measure. Please refer to our earnings release furnished with the SEC on February 27, 2024, for additional information on this non GAAP financial measure. At this time, it is my pleasure to turn the call over to Doctor. Samantha Du.

Speaker 2

Thank you, Christine. In 2023, we had another year of significant achievements for Zai Lab. We grew our top line by 31% on a constant exchange rate basis. We progressed several key late stage programs. We added new global assets into our pipeline.

Speaker 2

Today, we're in a fundamentally stronger position than we have ever been, with a growing base of revenues, a path to profitability and a strong balance sheet with over USD800 1,000,000 in cash. We are now entering a period of high growth and we are focused on 3 key corporate objectives: to substantially grow revenues, achieve profitability, and build our global pipeline. Late last year, we launched Vitgard and is already off to an excellent start with sales expected to exceed $70,000,000 this year in gMG. Beyond this, we have a series of other potential approvals, including repotrectinib and Sodor later this year, followed by a series of other new product indications, including escatetimod in CIDP, Bimatuzumab and CAR T. Each of these products have the potential to meaningfully enhance the growth of our business.

Speaker 2

We are also already deeply committed to building our global pipeline by adding new assets to both our internal discovery efforts and external opportunities. And I look forward to providing updates on our progress in this regard throughout the year. And of course, we'll maintain disciplined capital allocation practices as we strive to achieve profitability. As we execute on these corporate objectives, we expect to deliver value, not only to patients, but also to our shareholders. Thank you for your support as we continue on our journey of innovation and growth together.

Speaker 2

And with that, I'll pass the call over to Josh. Josh?

Speaker 3

Thank you, Samantha, and thank you everyone for joining the call today. Zai Lab delivered strong full year revenue growth of 25% year over year and 31% on a constant exchange rate basis, driven by robust volume growth across our existing product portfolio and the launch of VivGuard. These revenue increases were partially offset by an increase in sales rebates both in Q1 of 2023 in connection with new listings for our product on China's 2022 National Reimbursement Drug List or NRDL, and in Q4 of 2023 in connection with new and renewed NRDL listings for our products on China's 2023 NRDL. A pivotal achievement for us was the approval and subsequent launch of VIVGARD in September, followed by its inclusion in the NRDL, which became effective at the beginning of this year. Throughout the Q4, we implemented comprehensive commercial strategies to drive awareness and adoption of VIVGARD, and we entered 2024 with considerable momentum.

Speaker 3

I'm also pleased to announce that in 2023, we achieved our goal of having net product revenue exceed the cost of sales and sales and marketing expenses for our commercial products, which we refer to as commercial profitability. Our commitment to financial prudence remains steadfast as we work towards achieving and maintaining profitability. Lastly, we made substantial progress on key clinical development programs such as efgartigimod in CIDP and CAR XT in schizophrenia, while further enriching our global pipeline with the introduction of a next generation DLL3 ADC. In 2023, we announced our 5 year strategic plan aimed at positioning Zai Lab as a leading global biopharmaceutical company characterized by substantial revenue growth, achievement of profitability and a strong global pipeline. This strategic vision is underpinned by 3 corporate objectives.

Speaker 3

First, we are focused on accelerating top line growth. With a strong foundation in place supported by both new product approvals and label expansions within our existing portfolio, we anticipate substantial revenue growth in the coming years. By 2028, we aim to have a significantly larger commercial portfolio with the launch of potential blockbusters such as VIBGART leading the way. Subsequent potential launches include Saldor later this year entivdac, bemrituzumab and CAR XT in 2025 and beyond. Such launches would further drive revenue growth with our projections exceeding $2,000,000,000 in 20.28, reflecting our estimated 5 year compound annual growth rate of 50%.

Speaker 3

Furthermore, we are committed to building our global portfolio through internal discovery initiatives and strategic business development endeavors. Our goal is to advance at least 1 global IND into clinical trials annually as we continue to evaluate and pursue synergistic global and regional business development opportunities, leveraging Zai Lab's reputation as a trusted brand and preferred strategic partner. As we continue to grow and develop our commercial portfolio and pipeline, we remain focused on scaling with purpose and this brings us to our 3rd objective, which is to achieve corporate profitability by the end of 2025. To realize this objective, we will continue to enhance efficiency and productivity, prioritize research and development initiatives and execute cost optimization strategies. Our existing infrastructure is agile and sized to support multiple new launches.

Speaker 3

We maintained a robust reserve of cash and cash equivalents of $807,600,000 as of end of 2023, providing ample financial resources to sustain our operations through profitability and beyond. Now I will briefly review the performance of each of our commercial products and our expectations for 2024. Zejula maintained its position as the leader in hospital sales for PARP inhibitors in ovarian cancer in China, exhibiting growth in the Q4 and the entire year. In 2024, we will continue to focus on driving further growth in the first line setting and extending the duration of therapy. In 2023, Kinloch and the IV formulation of NUZYRA joined Zejula on the NRDL, and these listings help drive substantial sales increases for these products.

Speaker 3

We expect this positive momentum to continue, supplemented by the additional listing for the oral formulation of NUZYRA in January 2024. As Optune is a medical device and not eligible for NRDL inclusion, we are focused on expanding access and improving affordability for this important treatment through commercial health insurance coverage. Overall, we anticipate year over year revenue growth in 2024 for these 4 products in aggregate to be comparable to that of 2023. Turning now to the recent launch of VIVGARD. I want to take a moment to acknowledge the tremendous effort of our medical and regulatory and commercial teams behind VIVGART.

Speaker 3

We were able to reach important milestones at a swift pace, achieving our best case scenario with regards to the timing for approval, launch and NRDL listing. We are pleased to see the regulatory authorities recognize the innovation of VIVGARD and its substantial clinical benefit to patients living with generalized myasthenia gravis or gMG. In China, where there are over 170,000 patients with gMG, many patients endure residual symptoms making everyday tasks challenging and unpredictable. The scarcity of innovative therapies, the persistent shortage of IVIG therapy and the chronic and progressive nature of the disease can present a formidable challenge for both patients and healthcare providers alike, further underscoring the significance of VifGuard's approval. Throughout the Q4, our primary focus was on strategically targeting key hospitals and fostering awareness while delivering timely support to physicians and patients alike.

Speaker 3

And we made great progress. As of December, we had successfully engaged 100 percent of our top 200 target hospitals and over 90% of our top 100 physicians integrated VIVGART into their treatment protocols. Based on a survey of 250 physicians, awareness of VIVGART rose from 54% to 72 percent following 4 months of promotion, and we continue to see this rise. From launch in September through the end of the year, we estimate that nearly 1,000 patients were treated with VIVGART. Turning now to more recent updates on the launch.

Speaker 3

VIVGART listing on the NRDL became effective on January 1 this year with a price of $800 a vial or $32,000 per patient per year based on clinical study usage. We estimate that in January 2024 alone, nearly 1,000 new patients were treated with VIBGARD, indicating promising progress at this early stage of the launch. This demand is being driven by an unmet need in the treatment of gMG, a willingness of physicians to adopt VIVGART into treatment protocols and increased patient access as hospitals add VIVGAR to their formularies. We are very pleased with the progress achieved thus far with the launch of VIVGAR, and we anticipate sales to exceed $70,000,000 in 2024. Our strategic focus for the year will be to expand outreach to approximately 1,000 concentrated effort on accelerating VIVGAR listing at top tier hospitals.

Speaker 3

Already as of the end of January, our team has engaged 100 percent of our top 600 hospitals in person. Supported by our dedicated sales force of approximately 150 reps, we anticipate robust coverage to facilitate this expansion. Additionally, pending regulatory approval, we expect to launch VIVGARD's subcutaneous formulation for gMG later this year, which will offer enhanced dosing flexibility for physicians and patients. We're also excited about potential indication expansion for VIBGARD. This year, we expect to submit a supplemental biologics license application or SBLA in China for CIDP, which presents another substantial growth opportunity.

Speaker 3

This marks an exciting period for Zai Lab and an important year of execution for our team. And with that, I would like to pass the call to Rafael, who will provide an update on our oncology pipeline. Rafael?

Speaker 4

Thank you, Josh. Let me begin by highlighting some of the key progress updates in our oncology pipeline since our last earnings call along with our next steps. Starting with pemarituzumab, our FGFR2b inhibitor in collaboration with Amgen. We are enrolling in both FORTITUDE-one hundred and one and FORTITUDE-one hundred and two Phase 3 studies evaluating the marituzumab in FGFR2b positive gastric cancer as a doublet therapy with chemo and a triplet with chemo and a checkpoint inhibitor, respectively. We expect both studies to enroll well, and we're eager to introduce this much needed therapy to China, where we estimate an incidence of 126,000 FGFR2b positive gastric cancer patients each year.

Speaker 4

Next, our tumor treating field franchise. In January 2024, our partner Novocure announced that the FDA had accepted the filing of their pre market approval application for TTField in non small cell lung cancer following progression on or after platinum based therapy and a regulatory decision is expected in the second half of this year. In China, we expect to file a marketing authorization application for T cells in this indication later this year. We also expect 2 pivotal readouts for tumor treating fields, including in brain metastases from non small cell lung cancer and in pancreatic cancer, both in the first line setting. Also in lung cancer, repotrectinib is currently under priority review for the treatment of adult patients with locally advanced or metastatic ROS1 positive non muscle lung cancer in China.

Speaker 4

The filing was based on the results from the pivotal TRIDENT-one study, which were published in the New England Journal of Medicine in January this year. Findings demonstrated the potential of repotrectinib to overcome limitations of 1st generation tyrosine kinase inhibitors in terms of responses and durability in ROS1 resistant mutation. We look forward to a potential regulatory approval and launch this year to bring this best in class ROS1 TRK inhibitor to patients in need in China. Now moving on to adagracif, we will continue to accelerate the regulatory pathway for second line non small cell lung cancer monotherapy by leveraging the global data package for the FDA approval, the ongoing PK study in China and the global confirmatory CRYSTAL-twelve study, with Zai Lab joined in July 2022 and we await the results for a filing submission in China this year. In addition, our partner BMS announced this month that the FDA has accepted its supplemental NDA for priority review for adagracis in combination with cetuximab for the treatment of patients with previously treated KRAS G12C mutated locally advanced or metastatic colorectal cancer with a PDUFA goal date of June 21, 2024.

Speaker 4

For this indication, alagrassib has the potential to be the first to market KRAS G2C inhibitor in China. We completed enrollment in the global Phase III CRISIL-ten confirmatory study in 2023. Lastly, for TIFDAC, we have participated in the confirmatory Phase III INNOVA TV301 global trial in second line cervical cancer and continue an extension portion in China, and we intend to file a new drug application or NDA in China this year. In addition to our late stage programs, our DLL3 ABCZL1310 has shown promising preclinical data and is progressing through a global Phase 1 study in relapsed and refractory small cell lung cancer who has progressed after platinum based treatment in the United States and in China. In March, we will present the preclinical data at the European Lung Cancer Congress in Prague and depending on the dose escalation level, we could potentially see early clinical results at the end of 2024 or early 2025.

Speaker 4

We're also selecting internally discovered product candidates to achieve our goal of generating at least 1 IND per year, and we continue to assess external opportunities to introduce a new product in development this year. And now, I will turn the floor over to Doctor. Harald Reinhart to discuss the progress in our autoimmune, infectious disease and neuroscience therapeutic areas.

Speaker 5

Harald?

Speaker 6

Thank you, Rafael. This is truly a very exciting time for our neuroscience autoimmune infectious diseases or NSAID franchise as we made significant progress in the past year advancing our pipeline. Starting with Refguard or efgartegimod, beyond what Josh shared about the progress for gMG, we are excited about the positive data for treating patients with CIDP or chronic inflammatory demyelinating polyneuropathy. There are an estimated 50,000 patients diagnosed with CIDP in China and today only a small fraction are able to achieve remission on their current standard of care and the majority of patients continue to be burdened with symptoms that can have a debilitating impact on quality of life. Existing treatment options are limited and quite problematic given the general reliance on long term steroid or chronic immunoglobulin therapy.

Speaker 6

In China, the situation worsened due to the persistent shortage of IVIg therapy. Our partner, argenx, announced this month that the FDA had accepted for priority review the SBLA for subcu administered with Guard hydrolo in CIDP. It was granted a PDUFA goal date of June 21 this year. We plan to submit an SBLA to the NMPA in China for this indication in the first half of twenty twenty four. In addition, our SPLA for efgartigimod subcu in gMG is under regulatory review in China with potential NMPA approval this year.

Speaker 6

This approval would give patients flexibility on treatment with either IV or more convenient subcu dosing. Efgartigimod subcu has the advantage of simplicity and speed as administration takes only 30 to 90 seconds for a single dose. We see significant potential for efgartigimod across multiple additional indications and we will continue to work with our partner, argenx, on indication expansion. For example, we expect to join them in a registration study of efgartigimod in thyroid eye disease or TED in Greater China in the second half of this year. Turning to KAI XT, this is a 1st in class antipsychotic combining a centrally acting muscarinic agonist called cenomelene with a peripheral antagonist called trostium, which we are developing with our partner, Karuna, for patients with acute schizophrenia.

Speaker 6

In November 2023, the FDA accepted KORONA's NDA for CAR XT for the treatment of schizophrenia in adults with PDUFA goal date of September 26, 2024. We continue to enroll patients in the registrational bridging study in Mainland China, and we expect to complete enrollment this year. We believe that CARES T could become an important new treatment option in China, where more than 8,000,000 people are living with schizophrenia and where severe under treatment and inadequate symptom improvement or even disease control persists, despite currently available antipsychotics. We have yet another substantial opportunity for CAR XT, which is for the treatment and prevention of psychosis in Alzheimer's disease patients or ADP for short. There are approximately 8,000,000 people with Alzheimer's disease in China and about 45% of these patients display psychotic symptoms.

Speaker 6

We believe that there is a significant unmet need for patients with ADP or Alzheimer's disease psychosis in China as there are no approved treatments. Karuna initiated the Phase 3 ADEPT 2 and ADEPT 3 clinical trials in the Q3 of 2023, and we plan to participate in both studies in Greater China in mid-twenty 24. Regarding our infectious diseases portfolio, Sulbactam, dorlobactam or SulDor is a treatment for hospital acquired and ventilator associated bacterial pneumonia caused by Acinetobacter baumannii. In China, there are 240,000 to 300,000 cases of Acinetobacter infections annually with the majority of strains being carbapenem resistant. Latest countrywide surveillance data from China indicate a rise in overall resistance to approximately 80%.

Speaker 6

With limited treatment options for these patients, the mortality rate is around 43% even with the best available therapy and care. The WHO has listed Acinetobacter baumannii as the number one problem pathogen and the high incidence in China has prompted the Chinese government to prioritize efforts to combat this multidrug resistant bacteria. Our NDA submission is under priority review, and we are looking forward to a potential approval later this year. Last not least, CL-eleven oh two, our IL-seventeen tumor body for the topical treatment of chronic plaque psoriasis or CPP is in the final stages of preparation for a global Phase 2 dose finding trial and we intend to initiate the study in mid-twenty 24. So plenty of exciting progress within our NSAID portfolio and I look forward to providing updates at our next earnings call.

Speaker 6

Now, Yijing will provide an overview of our financial results. Yijing?

Speaker 5

Thank you, Howard. Now I will discuss our full year financial results compared to the prior year. In 2023, total net product revenues grew to $266,700,000 This represents year over year growth of 25% or 31% on a constant currency basis. Our revenue growth was driven by increased sales volumes and the launch of VIVIGAR, partially offset by an increase in our sales rebate to distributors, resulting from price reductions in connection with the additional NRDL listings. Sales rebates in connection with NRDL listings rose to $13,000,000 for 2023.

Speaker 5

This Enabio listings play a crucial role in maintaining patient access to our existing products on Enabio, while significantly expanding access for our new products. Growth was also negatively impacted by the temporary effects on the hospital and the physician practices that resulted from industry wide anti corruption enforcement efforts in China in the second half of the year. Now looking at each individual product, Zejuna net product revenue increased 16% year over year to $168,800,000 in its 3rd year under Nardio, driven by increased hospital sales in first line ovarian cancer and the duration of treatment improvement, partially offset by an increase in sales rebates in the 4th quarter in connection with the renewal of the NRDL listing for Zejula as a maintenance treatment. VIVIGUARD's net product revenue was $10,000,000 following the launch in China in September 2023. We successfully negotiated for Vivigard's first listing on the NRDL with pricing that took effect on January 1, 2024.

Speaker 5

Optune net product revenue were relatively flat year over year at $47,000,000 as continued growth in supplemental insurance coverage was offset by the disruption in hospital and physician practices, resulting from anti corruption efforts. TRULOG grew 29% year over year to $19,200,000 and NUZYRA increased 316% to $21,700,000 This growth was supported by the inclusion of Kinlox and the IV formulation of NUZYRA in the Enabio in the Q1 of 2023, partially offset by sales rebate in connection with this Enabio listing as well as sales rebates in the Q4 in connection with the inclusion of the oral formulation of NUZYRA, which became effective in January 2024. Turning now to our expenses, research and development expenses declined $21,000,000 to $265,900,000 primarily due to decreased upfront and milestone payments for our license and collaboration agreements, partially offset by an increase in personnel compensation and related costs. Selling, general and administrative expenses grew $23,000,000 to $281,600,000 primarily due to higher general selling expenses to support the launch of ViviGuard, partially offset by a decrease in professional services fees. Both R and D and SG and A expenses significantly declined as a percentage of revenue and we expect this trend to continue as a result of our growing revenues and our ongoing cost and efficiency initiatives.

Speaker 5

Zai Lab reported a net loss of $334,600,000 for 2023, which improved by $108,000,000 versus prior year. The decrease in net loss reflects our continued progress towards profitability, primarily driven our product revenue growing faster than net operating expenses, as well as increased interest income and decreased foreign currency loss. We are in a strong financial position ending the year with a cash position of $807,600,000 compared to $1,000,000,000 as of December 31, 2022. Based on our operating plan and our anticipated revenue growth, we expect to be able to fund our business through profitability. And with that, I would now like to turn the call back over to the operator to open up the line for questions.

Speaker 5

Operator?

Operator

We would now like to open the line for questions. Our first question comes from the line of Michael Yee from Jefferies. Please go ahead. Your line is open.

Speaker 7

Hi, this is Zhao Jiwei on the line for Michael Yee. Thanks for taking my questions and giving a great mid guard guidance, which is obviously above the consensus. I have a couple of questions. Maybe first, can you comment on what your assumptions are for the $17,000,000 in 2024 VIVEGAR sales guidance? And what visibility you have to be able to guide the $70,000,000 and for the 1,000 new patients added in January, were they a bonus waiting for the NIDL price to be treated or due to other factors in play?

Speaker 7

My second question is about the recent investor concerns and rhetoric in Washington DC about the committee on CCP. Maybe can you comment on what your confidence level is that you believe this won't impact biotech at all and what you're seeing out there? Thank you.

Speaker 8

Great. Thank you for the questions. It's Josh. I'll direct the question to our leadership team here, but I think for the first two, I'll direct them back to me. First on VIVGARD, as we said, we're really pleased with the uptake we've seen so far.

Speaker 8

We're monitoring all the normal leading indicators you would look at in a launch, but new patient starts is really important. So I think our what gives us the confidence to say we're on a path to $70,000,000 or greater in 2024 is the rate of new patient starts, the penetration we're seeing with hospitals where we focused in the 4th quarter on the top 600 hospitals, which make up about 80% of sales opportunity. We'll expand that to 1,000 hospitals here in the first half of the year, now that we have NRDL listing. And one of the things we look at there is how quickly the hospitals adopt the NRDL national listing into their local formularies. We're off to a good start there.

Speaker 8

1,000 patients in January, as we mentioned, I think is a really good start. And it's I think it's it's obviously, it's very early in the launch. To get into too many details there, we'll keep updating as we go through the quarters during the year. But I think what we can say right now is with 1,000 new patients and of course as we mentioned last year, some of those patients could have been patients that would have started in December, but were held for the reimbursement. But I think for the most part, we're quite pleased with the absolute magnitude in the number and it gets us off to a good start in the year.

Speaker 8

And again, I would look at the $70,000,000 as we know enough now to have confidence there and we're looking forward to continued progress throughout the year. I think on the second question about the political environment in U. S. And the BioSecure Act and or others, we've evaluated these bills and the tenor behind them closely. We don't they don't touch on anything that we do and we're quite confident that as proposed now these bills or activities won't have any impact on what we do as a biotech company focused on bringing great innovative medicines to patients in China and over time to the rest of the world.

Speaker 8

Thank you.

Speaker 7

This is great. Thank you.

Operator

Thank you. We'll now move on to our next question. Our next question comes from the line of Anupam Rama from JPMorgan. Please go ahead. Your line is open.

Speaker 4

Hey, guys. Thanks so much for taking the question. Maybe just a broader question for me. So what evidence or anecdotes do you have that some of the corruption efforts in China have kind of played out and won't have a lingering impact moving forward? Thanks so much.

Speaker 8

Thanks, Anupam. It's Josh again. I think first, we look at how our sales reps are able to interact with their customers, hospitals and physicians and otherwise. And I think what we see now is we've got good access. We're able to communicate the medical benefits of our products in a way that's helpful to physicians and patients and so on.

Speaker 8

So I think that's what we tend to look at. I think on the broader level, of course, it's we can't predict the future. But for now, we feel good about the environment we're operating in and certainly our sales and marketing practices are of the highest standards and no impact that we've seen from the historical efforts there. So we're looking forward to a good year operationally here.

Speaker 9

Thanks so much for taking the question.

Speaker 4

Thank you.

Operator

Thank you. We'll now move on to our next question. Please stand by. Our next question comes from the line of Louise Chen from Cantor.

Speaker 10

So I wanted to ask you on CIDP, if you do get approval, how do you think the uptake will be relative to what you've seen right now for myasthenia gravis? And then what's a bigger opportunity for you, MG or CIDP? Thank you.

Speaker 8

Thanks, Louise. I'm going to ask Harold to talk a little bit about the CIDP and answer your question. And if there's anything to wrap up on, I'll come back at the end. Please go ahead, Harold.

Speaker 6

Yes. Hi. Thank you for the question. The CIDP indication is rather unique. It is an unmet medical need situation here much more so than in many other indications for autoimmune diseases.

Speaker 6

These patients currently really lack something like an efgartigimod that helps improve symptom autologie and to break the downslope of their disease. A lot of these patients end up in wheelchairs. So right now, as we said earlier, treatment is just steroids. And at the end of the rope, you get patients who are getting constantly IVIG infusions. So we see really a very, very important role for efgartigimod in that population.

Speaker 6

This efgartigimod treatment here is a weekly treatment for the duration of the symptomatology. So it has a major impact on our financials. Thank you.

Speaker 8

I would just add, as Harold mentioned, there's a significant unmet need here and it's a very big opportunity. I don't think at this point, Louise, we're going to be excited about both of them. I think they both present large opportunities both G and A and CIDP and we're looking forward to progressing the CIDP approval process and be ready to go there. Thanks.

Operator

Thank you. Thank you. We'll now move on to our next question. Our next question comes from the line of Yigal Nochomovitz from Citigroup. Please go ahead.

Operator

Your line is open.

Speaker 9

Yes. Hi. Thanks very much. On the on VIVGAR, I think, Josh, you mentioned it was 32,000 per year based on clinical study usage. How is that syncing up with what you're seeing in the real world in terms of the average number of cycles and average vials per 4 week cycle?

Speaker 9

Is that fairly consistent with clinical trial experience so far? Thanks.

Speaker 8

Thanks, Yigal. I'll ask Harold to comment, but I think it's early in the launch. We have no reason to believe that we're going to see things that are vastly different than what we're seeing around the world. We're excited about the starting point. But I don't know that we have a lot more to offer now.

Speaker 8

Harold, if you have any comments you

Speaker 3

to make?

Speaker 6

Not really. In this case, we are still too early in the use in the pattern and the numbers of cycles that we would expect to see. Right now, given the same labeling as in the U. S, we assume a very similar uptake. However, this needs to be further defined and only future updates here will be able to give you the details that you probably want to hear.

Speaker 9

And then Josh, you sort of referenced that the year on year growth for the 4 products in the market, not including VIVGAR, would be comparable to 2023 year on year growth. However, if you look at the trajectory from Q3 to Q4 in 2023 for Zejula, Optune and Clinlock. I guess it's a little unclear how you're going to be able to achieve the same year on year growth for those products. For Nxira, also it was a very, very large number. So could you just kind of expand a little bit on how you're thinking about that year on year growth number given what we're seeing in the second half of twenty twenty three for Quinloc, Optune and Zejula?

Speaker 9

Thanks.

Speaker 8

Thanks, Yigal. I think first, for Q4, I want to remind everybody that the Q4 growth rate for Zejula certainly is impacted by rebates associated with NRDL. So I think if you look at the portfolio overall for Q4 and you take out the rebate comparison or drag, growth is more like 19%. So I think certainly for Zejula, we saw market share grow through the year and we expect to continue to grow in 2024. So I think that product is performing well and we'll continue to push it.

Speaker 8

I think with the other 3, I mean between the 3 of them, there's some ups and downs and otherwise, I think NUZYRA, we with the NRDL listing now for the oral formulation, I think we're in a good position to continue to see good growth for that product in 2024. I think with Optune, it's a medical device, so there were some challenges, I think, for that product overall. But we expect to grow it. It provides an important benefit to patients and we expect to continue to grow that in 'twenty four. And Kinwalk is performing about what we would expect.

Speaker 8

It's a small product, but it's an important foundational drug for us as we think about gastric cancer. So I think you put those all together, there's no reason for to believe that the overall sales growth we saw in 2020 3 can't be replicated in 2024.

Speaker 9

Okay, thanks. And then just last question on the IL-seventeen. I think you mentioned just starting the global study in plaque psoriasis. Where do there were some discussion in past meetings over the years with respect to partnering that globally with a large pharma. Where does that stand?

Speaker 9

And can you just update us on your strategy for that product? Thanks.

Speaker 8

Harold, you can comment on the study. I think we're excited to get going and begin to create clinical data and then we'll evaluate our options as we proceed. But Harold maybe can give us an update.

Speaker 6

Yes. Thank you. Yes, we are happy to go into Phase 2 with this program. And as far as the question here about partnering, I think we are always open to partnering offers and looking at increasing value here for the product. Otherwise, I would like to defer the question to Jonathan who is on the call.

Speaker 11

Yes. I think we'll evaluate as the data coming, but it's probably too early at this stage to think about partnering.

Speaker 3

Thank you, Yigal.

Speaker 9

Okay. Thank you.

Operator

Thank you. We'll now move on to our next question. Our next question comes from the line of Linhai Zhao from Goldman Sachs. Please go ahead. Your line is open.

Speaker 12

Hi. Thanks for taking my question. Just wondering for Optune, we know that there are indication expansion opportunities, particularly we have 2 Phase 3 readouts in 2024 and we are planning to filing for the second line of most cell lung cancer in China following our partners following in FDA. So wondering if the management can share a bit more on the indication expansions, particularly for these three indications. And also, with all the debates on the second line non small cell lung cancer with the LUNAR data, can you share a bit more color on our communications with the China regulators about the potential concerns and how we are going to address their potential concerns on that aspect.

Speaker 12

And on that, for 2028, as part of our $2,000,000,000 revenue target, how much do you see revenue contribution from Optune in 2028? Thanks.

Speaker 8

Rafael, why don't you address the question, please?

Speaker 4

Yes. Thank you. This is Rafael. Maybe I'll start LUNAR-two. And as I said in the prepared remarks, Enovocure has announced that the FDA has accepted the pre market authorization in January.

Speaker 4

And as you know, the review time is 180 days. You asked about our interactions with regulatory authorities in China. We are starting those interactions, and we have a really good collaboration with our partner. And our intention is to file this year and we will need for that the China subset analysis and we're collaborating as I said really well with our partners NovoCure to be able to file this year. So obviously, we will see how it goes with FDA, but as I said, the PMA has been accepted.

Speaker 4

And then with regards to additional indications, NovoCure has announced some of those. I guess the one that's most immediate is the LUNAR-two study, which includes checkpoint inhibitors and chemotherapy plusminus the device in frontline non small cell lung cancer, line on container regimen. We are considering participating in that trial and in discussions with them. And then there's an ongoing study with checkpoint inhibitor for patients with high GBM scores, which is a Phase II study, which we're awaiting the results. But in terms of Phase 3 studies, most important readouts are medicine on small cell lung cancer patients with brain metastases as well as locally advanced pancreatic cancer, PANOVA trial.

Speaker 4

We've participated in both of those studies to put sufficient patients and we're eagerly awaiting the results of those trials which should be this year and then we'll add accordingly. So this is sort of an overview of where we are with all these programs, the future programs that we may participate, the ones that we have that we are awaiting results. And definitely, we are committed to filing with LUNAR and, as I said, start interactions already with the device division of NMDA?

Speaker 8

I think as it relates to the 2028 composition, we looked at a range of outcomes here when we put together that guidance and that goal. It wasn't dependent on any single product. Although what I can tell you for sure is VIVGART is the start that we have there and our excitement around gMG and CIDP, I think is the biggest driver for what puts us on the path to the 2028 goals. Thank you.

Speaker 6

Thank you.

Operator

Thank you. We'll now move on to our next question. Our next question comes from the line of Jonathan Chang from Leerink Partners. Please go ahead. Your line is open.

Operator

Open.

Speaker 13

Hey, guys. This is Matt Cowper on for Jonathan. Thanks for taking my question. I was just wondering if you can discuss how you see the pricing of Vistgard evolving over particularly in the context of NRDL renewal cycles and then also in the context of adding additional indications such as CIDP? Thank you.

Speaker 8

Thanks, Matt. I'll ask Jonathan to take that one, please.

Speaker 11

Sure. Thanks for the question. Look, I think first, we achieved a good price at the end of last year in the NRDL negotiation. So we're off to a very good starting point. And I think NRDL is also evolving and we do see positive trends as the government increasingly supportive of innovative and differentiated products.

Speaker 11

VIVGAR being the only in class and addressing a very large unmet medical need in China is a program which we see that the government is supporting and we do expect to maintain good price. Also if you look as a jeweler, we maintain very good price in the most recent negotiation. So we feel pretty good about the pricing at this stage.

Speaker 6

Thanks, John.

Speaker 13

Yes. Thank you.

Operator

Thank you. We'll now move on to our next question. Our next question comes from the line of Jack Lin from Morgan Stanley. Please go ahead. Your line is open.

Speaker 14

Hi, good morning everyone and thank you for taking my question. I have a couple of quick questions. First one again on the Vipcar, Curious to know if there's any color you could share in terms of the patient background that we've seen since the Q4 and also in January. What proportion of them were refractory versus kind of in the earlier setting? And for the refractory ones, how what might be the breakdown between refractory to the conventional oral immunotherapies versus the alternative biologics?

Speaker 14

That's on the VITCAR. And just two really quick questions on commercialization. One, I think you mentioned earlier, we're looking to break into 1,000 hospitals by end of this year. And I think we're at 150 right now. Curious to know about how the commercial team is is it in place or is it kind of ongoing effort to for more recruitment?

Speaker 14

And also for Optune, assuming that we have success from the ANOVAL-three studies and others, will we rethink in terms of the getting reimbursement coverage in China considering the significantly larger patient size? Thank you.

Speaker 8

Thanks, Jack. I'll ask Harold to talk a little bit about VIVVARTA patients. Obviously, it's very early in the launch, but Harold, do you mind making comments?

Speaker 6

Yes. Thank you for the question. And again, the patient background that we've seen so far is really the background of those patients who were prior to NRDL reimbursement. So those patients, we would assume, are the patients who are somewhat more sick and more ill and possibly close to the refractory part of the disease cycle. However, this will all mobilize, we believe, as NRDL pricing kicks in, and we should expect a similar kind of patient population going forward that has been seen in the studies and also in the United States.

Speaker 6

So this is a drug which comes in after steroid use. It's not a drug for the refractory patients. Only it is a patient selection that we see right in the middle is the bulk of patients for with gMG that starts to lose control with steroids alone or run some new side effects with steroids.

Speaker 3

Thank you, Harold.

Speaker 6

This is fairly early in the day and we shall

Speaker 8

Jack, your question about some of the commercialization efforts. So, when we launched in September, we had 100 sales reps that we focused on the top 600 hospitals, which as I mentioned earlier, we have about 80% of the sales opportunity that we were focused on. With NRDL listing, we always plan to move from 100 reps to 150. We're in the middle of that expansion right now. And we would increase our target hospital list from 600 to 1000 and that comes with the expansion of reps.

Speaker 8

We'd expect all of that to be complete over the first half of this year. So, I think as you get into the second half of the year, we'll be at what we believe to be full strength and I think that's sufficient to cover the opportunity given how concentrated the prescribing and the patient base is here. So again, we're excited about what we're seeing so far and we think the opportunity is well defined and in front of us. Jonathan, I don't know if you have any comments you want to make on sort of the longer term pricing policy opportunities for medical devices and how often they fit in there?

Speaker 11

Yes, it's also evolving very rapidly. As you recall, about a year and a half ago, the government was having draft proposals on the medical device, NIDL inclusion. So far they haven't come up with a more formal guidelines yet. So we're eagerly wait for that. We think if that does eventually, obviously Optune would benefit.

Speaker 11

But for now, I think the commercial insurance is very important for Optune and it's a viable market just based on that. Thank you.

Speaker 7

Thank you.

Operator
