아베오나 테라퓨틱스(ABEO) 2026년 2분기 실적 발표: ZEVASKYN 매출 31% 증가

핵심 요약

• 아베오나 세라퓨틱스는 2026년 2분기 제바스킨 순매출이 2026년 1분기 870만 달러에서 31% 증가한 1,140만 달러를 기록했다고 발표했다.
• 해당 분기 동안 5명의 환자가 제바스킨 치료를 받았으나, 1개 배치가 청구 가능한 세포 수율 기준치에 미달하여 4건의 치료에 대해서만 매출이 인식되었다.
• 출시 이후 현재까지 2분기 5명과 3분기 현재까지 3명을 포함해 총 12명의 환자가 치료를 받았다. 3분기의 별도 규격 미달 배치는 환자에게 투여되었음에도 불구하고 매출이 발생하지 않았다.
• 신시내티 어린이 병원이 추가되면서 인증 치료 센터(QTC) 네트워크는 7곳으로 확대되었다. 보험 청구 분석에 따르면, 전체 잠재시장(TAM)의 약 40%가 현재 주 내에서 QTC에 접근할 수 있다.
• 2026년 6월 30일 기준 현금, 현금성 자산 및 단기 투자 자산은 총 1억 4,680만 달러였다. 회사는 분기 순손실 2,020만 달러(주당 0.35달러)를 기록했다.
• CMS는 2026년 10월 1일 자로 제바스킨에 신기술 추가 지불(NTAP) 지위를 부여했다. 경영진은 메디케어가 RDEB 지불자 구성의 약 10%를 차지한다고 밝혔다.

주요 재무 데이터

사업 및 영업 성과

전국적으로 7개의 인증 치료 센터가 운영되며 제바스킨의 시장 진입이 계속 확대되었다. 2분기 중 뉴욕-프레스비테리언/컬럼비아 대학교 어빙 메디컬 센터와 필라델피아 어린이 병원이 활성화되었으며, 최근에는 신시내티 어린이 병원이 추가되었다.

필라델피아 어린이 병원(CHOP)은 5월 활성화 이후 7월에 첫 치료를 완료했다. UTMB는 첫 환자 생검을 완료했다. 경영진은 추가 EB 센터들이 네트워크 참여를 요청했으며, 아베오나는 네트워크 확장을 계속할 계획이라고 밝혔다.

회사는 치료 건수 증가의 주요 제약 요인으로 운영상의 복잡성을 꼽았다. 제바스킨은 유통기한이 84시간에 불과해 피부과 의사, 외과의사, 마취과 의사, 병원 직원, 수술실, 지불자 및 환자 간의 조율이 필요하다. 2분기에는 환자의 건강 상태 악화로 인해 예정된 생검 2건이 단기간 내에 취소되었다.

제조 생산량은 상업용 배치당 평균 약 9장으로, VIITAL 임상 3상 시험의 환자당 약 5장과 비교된다. 아베오나는 최대 12장까지 공급할 수 있다. 4장 미만을 생산하는 배치는 저수율로 분류되어 매출 인식 요건을 충족하지 못하지만, 여기서 생산된 시트는 치료에 사용될 수 있다.

CMS는 2026년 10월 1일 자로 제바스킨에 2027 회계연도 NTAP 지위를 부여했다. 이 프로그램은 입원 치료 중 사용되는 적격 고가 치료제에 대해 병원에 추가 상환을 제공한다. 경영진은 이번 결정으로 메디케어 수혜자의 접근성이 향상되고, 나아가 지불자들과의 협상 전반에 긍정적인 영향을 미칠 것으로 기대하고 있다.

경영진 전망

경영진은 센터가 안정적인 운영 단계에 도달하면 QTC당 월평균 1명의 환자를 치료하는 일정이 달성 가능한 목표라고 계속 보고 있다. 개별 센터가 활성화에서 치료로 전환하는 속도에 상당한 차이가 있음을 지적하며 구체적인 일정은 제시하지 않았다.

아베오나는 대부분의 제조 비용이 고정비이기 때문에 풀 가동 시 매출총이익률이 약 85%~90%에 달할 수 있다고 밝혔다. 회사는 또한 일정한 치료 주기를 유지한다면 지속 가능한 현금흐름 흑자 사업 모델을 달성할 수 있다고 보고 있다.

향후 분기별 실적 발표는 예정된 생검이나 제조 중인 배치와 같은 초기 단계 지표보다는, 해당 분기 내 완료된 치료 건수와 인식된 순매출에 집중할 예정이다.

리스크 및 주요 점검 사항

• 치료 일정은 환자의 질병, 일정 차질, 지불자 승인 절차, 수술실 이용 가능 여부에 여전히 취약하다.
• 84시간의 제품 유통기한은 여러 당사자 간의 정밀한 조율을 필요로 하며, 임박한 취소가 발생할 경우 유연한 대응을 제한한다.
• 입고되는 생검 원료의 변동성은 제조 수율에 영향을 미쳐 청구 불가능한 배치를 생성할 수 있다.
• 아베오나는 2분기에 1건의 저수율 배치와 3분기에 1건의 규격 미달 배치를 기록했다. 회사는 해당 제조 비용을 자체 부담했으며, 두 치료 건 모두에서 매출을 인식하지 않을 예정이다.
• 규격 미달 결과는 Pan-CK 동정 시험과 관련이 있었다. 경영진은 제품의 안전성이나 유효성과는 무관하다고 밝혔으며 FDA와 해당 규격에 대해 논의 중이지만, 시기와 결과는 여전히 불확실하다.
• 센터별 생산성은 변동성이 매우 크다. CHOP는 활성화 후 약 2개월 만에 환자를 치료한 반면, 일부 센터는 12개월이 지난 후에도 환자를 치료하지 못했다.

애널리스트 Q&A 주요 내용

경영진은 지역 의사와 QTC에 의해 임상적으로 치료 적격성이 확인된 환자가 100명 이상이었다고 밝혔다. 그러나 상담, 지불자 승인, 생검, 제조 및 인증 센터에서의 치료로 환자를 진행시키는 과정이 여전히 병목 단계로 남아 있다.

제조 신뢰성과 관련하여 경영진은 지금까지의 경험에 비추어 저수율 배치는 드문 사건이라고 설명했다. 상업용 배치는 평균 9장을 기록했지만, 회사는 장기적인 청구 불가능 배치 비율을 추정하기에는 표본 크기가 여전히 너무 제한적이라고 밝혔다.

Pan-CK 결과와 관련해 아베오나는 기존 규격이 상업용 GMP 제조 경험이 아닌 BLA 심사 당시 이용 가능했던 6개 샘플에 기반한 것이라고 밝혔다. 회사는 추후 분기 보고서를 통해 FDA와의 논의 진행 상황을 공유할 예정이다.

경영진은 최근 환자의 건강 문제로 취소된 2건의 생검이 환자가 제바스킨 치료를 영구적으로 철회한 것이 아니라 연기된 것임을 명확히 했다. 환자 파이프라인과 QTC 네트워크 확대는 이러한 차질이 분기별 실적에 미치는 영향을 줄이기 위한 것이다.

보험 상환과 관련해 경영진은 NTAP이 메디케어가 보장하는 RDEB 지불자 구성의 약 10%에 주로 영향을 미친다고 밝혔다. 이 혜택은 아베오나의 마진 구조를 직접 변경하기보다는 메디케어 환자 치료에 따른 잠재적 재정 부담을 줄임으로써 주로 치료 센터에 귀속될 것으로 예상된다.

Good morning, everyone, and welcome to Abeona Therapeutics 2Q 2026 Conference Call. [Operator Instructions] Please note this conference is being recorded.

I will now turn the conference over to your host, Gregory Gin, Vice President, Investor Relations and Corporate Development. Greg, the floor is yours.

Gregory Gin

Thank you, Jenny. Good morning, and thank you, everyone, for joining us on our second quarter 2026 results conference call. During this call, we will refer to the press release issued this morning announcing the financial results. It's available on our corporate website at www.abeonatherapeutics.com.

Joining me on today's call are Dr. Vish Seshadri, Chief Executive Officer; Dr. Madhav Vasanthavada, Chief Commercial Officer; Joe Vazzano, Chief Financial Officer; and Dr. Brian Kevany, Chief Technical Officer. We anticipate making projections and forward-looking statements during today's call, which are made pursuant to the safe harbor provisions of the federal securities laws. These forward-looking statements are based on current expectations and are subject to change. Actual results may differ materially from those expressed or implied in the forward-looking statements due to various factors, including, but not limited to, those outlined in our Form 10-K and periodic reports filed with the Securities and Exchange Commission. These documents are available on our website at www.abeonatherapeutics.com.

And with that, I will now turn the call over to Vish Seshadri to please start. Vish?

Vishwas Seshadri

Thank you, Greg, and good morning, everyone. I'll begin today with an overview of our commercial progress before turning the call over to Madhav for operational details. Our commercial experience to date reinforces our confidence in ZEVASKYN's substantial commercial opportunity. During the second quarter, we advanced our rollout by expanding our qualified treatment center network and progressing more patients through the treatment pathway. With the recent addition of Cincinnati Children's, which is one of the largest epidermolysis bullosa treatment centers in the country, we now have 7 activated QTCs nationwide. Importantly, CHOP and UTMB are biopsying patients and CHOP has completed its first treatment.

We have treated 12 patients since launch, including 5 in the second quarter of 2026 and 3 additional patients in the third quarter to date. As Madhav will discuss further, a couple of these treatments did not generate revenue. As our commercial footprint expands, we're refining how we report progress to the investment community. Over the past quarter, we have seen that leading indicators such as scheduled biopsies or biopsies in manufacturing are subject to external variables outside our control and have limited utility in predicting revenue-generating treatments.

Later on the call, Joe will outline the specific reporting updates we're making to eliminate this uncertainty and to align with standard practices of commercial stage companies.

With that, I'll turn the call over to Madhav Vasanthavada, our Chief Commercial Officer, to detail our commercial execution and network expansion. Madhav?

Madhav Vasanthavada

Thank you, Vish, and good morning, everyone. We are making progress in executing the launch with clear priorities, advancing identified patients through the treatment journey, strategically expanding the QTC footprint by onboarding leading EB centers and raising ZEVASKYN awareness across the EB community. Let me start with EB community engagement since we just attended back-to-back meetings, the Debra Care Conference, which is a flagship meeting for EB patients hosted by Debra of America, a patient advocacy group, and the Society of Pediatric Dermatology, SPD, Annual Meeting, where we interacted with dozens of highly engaged patients, caregivers and physicians.

Patient ambassadors from our Strong Together Network which is a group of patients who received ZEVASKYN in clinical trials, engaged with families and physicians throughout these events, fostering meaningful dialogue, sharing the impact ZEVASKYN has had on their lives and helping connect patients and caregivers with ZEVASKYN resources and support. Following these interactions and the many that we have been having in the recent months, we are energized by the opportunity and the fundamental role ZEVASKYN can play in healing RDEB wounds today and for the years to come.

Based on our interactions with patients and caregivers, we continue to believe that the distinct value of ZEVASKYN is deeply resonating with the RDEB community. We see clinical conviction building across our QTC network and the community practices of other RDEB physicians. While we are thrilled with the patient community's interest in ZEVASKYN, our recent experience has revealed bottlenecks that we are working through in the journey from patient identification to ZEVASKYN treatment. Because ZEVASKYN is the first surgically applied autologous cell therapy in dermatology and is operationally very different from traditional topical therapies, QTCs have a steep learning curve to client. As a result, the time from patient identification to patient treatment can vary considerably site to site and be influenced by a broad range of factors that are beyond the control of individual stakeholders.

Executing the launch has provided us with several real-world learnings, of which I'd like to highlight 3 important ones. First, administering ZEVASKYN, which has an 84-hour shelf life, requires a QTC to execute seamless real-time coordination across multiple stakeholders. Well before requesting a biopsy slot, dermatologists, surgical specialists, anesthesiologists and hospital staff must lock in precise dates for biopsy appointments for operating room reservations and for surgeon and medical teams. These unique operational dynamics require even greater planning, particularly when patient and physician availability can be limited with holidays and back-to-school planning, and we have seen this lead to scheduling disruptions for biopsy and treatment dates.

Second learning, on the clinical side, we have observed that the health of harder patients can sometimes change unexpectedly, which can lead to unavoidable biopsy delays or cancellations. In the second quarter, patient health deterioration resulted in 2 last-minute cancellations of scheduled biopsies. Because of the amount of coordination required at the QTC with payer and patient schedules well before booking the treatment slot, a last-minute cancellation means that the slot cannot be filled by another patient.

Lastly, on the supply side, as our patient sample size has continued to grow, we have learned that manufacturing yields can be influenced by variability in the incoming biopsy material. These factors resulted in 1 low-yield batch in Q2 and 1 out of specification batch in Q3, for which no revenue was recognized. Despite these challenges, we are gratified that both patients received treatment.

While the launch has highlighted these complexities, they have provided valuable operational and commercial learnings that continue to strengthen execution by both Abeona and its QTC partners. Importantly, despite these complexities, we have maintained a steady quarterly growth and 12 patients have now been treated with ZEVASKYN since launch. As we apply these launch learnings, our focus remains on ensuring more patients enter the top of the funnel to help offset patient attrition that can occur for reasons beyond our control.

A key component of that strategy is continued expansion of our qualified treatment center network, continued engagement with the EB community and improving patient access. Towards that end, during the second quarter, we activated 2 leading institutions, New York-Presbyterian, Columbia University Irving Medical Center and Children's Hospital of Philadelphia, CHOP. More recently, Cincinnati Children's Hospital, one of the largest ED centers in the U.S. has come on board. Activating treatment sites has taken significant time and commitment from QTCs and Abeona teams, and I want to thank everyone involved who helped achieve our stated goal of activating 7 QTCs by the end of this year.

With our expanded QTC network, about 40% of our addressable market now has in-state access to a QTC based on claims analysis. In addition, our QTCs also provide specialized care for a sizable portion of patients traveling from out of state, which enables even broader patient access. That said, we are getting requests from additional EB centers to onboard ZEVASKYN, and we plan to work with those centers to further our expansion of the QTC network. While site activation is a critical milestone, it is only a first step that allows a QTC to initiate ZEVASKYN treatment process, including consultation, patient workup and payer engagement.

Our commercial and medical teams continue to communicate regularly with each activated center as they build treatment readiness and administrative planning, including pharmacy and therapeutics committee review, prior authorization and payer agreement processes and planning for surgery and logistics. As an example of exceptional operational efficiency, CHOP completed its first ZEVASKYN treatment in July, shortly after its activation in May. UTMB recently completed its first patient biopsy, representing another important step towards future treatments and overall, reflecting growth in the number of QTCs that are treating patients.

Next, as we think about the long-term adoption curve for ZEVASKYN, we know that physician confidence and learning builds over time. Our QTC physicians rely heavily on multicenter real-world experience shared through peer-to-peer dialogue before transitioning a new therapy like ZEVASKYN into standard practice. As we actively facilitate best practice sharing amongst QTCs and the early treaters observe positive post-treatment outcomes and share them with their peers, we believe that this growing clinical conviction will trigger the tipping point that bridges initial experience to broad clinical adoption and routine prescribing across our entire QTC network.

Based on recent discussions with RDEB physicians, we expect that enthusiasm for ZEVASKYN will continue to build as RDEB physicians see and share even more examples of positive treatment outcomes. Equally important for adoption is ensuring economic alignment and reimbursement for our treatment centers across all payer channels. To that end, we achieved a significant milestone from CMS, granting new technology add-on payment or NTAP status for ZEVASKYN effective October 1, 2026, for fiscal year 2027.

NTAP is a CMS program that provides hospitals with supplemental reimbursement for eligible new high-cost and innovative therapies during inpatient stays, helping to cover the costs beyond standard DRG payments. For fiscal year 2027, CMS had received 15 new applications under the traditional pathway, and ZEVASKYN was 1 of only 3 to achieve NTAP status. The other 12 either did not meet the requirements or withdrew their applications or were denied. We are pleased that CMS has granted ZEVASKYN a new technology add-on payment. This is a significant recognition that comes after months of clinical -- rigorous clinical review and public commentary. And it is an external validation of the newness, cost criterion and substantial clinical improvement that ZEVASKYN offers over existing treatment options for RDEB.

While Medicare represents about 10% of RDEB payer mix, NTAP now provides a mechanism for hospitals to seek a substantial add-on reimbursement and facilitate patient access. In closing, we remain encouraged by the demand we see and are focused on ensuring eligible patients can receive ZEVASKYN. Our approach is to achieve this by building robust access, expanding our QTC networks and further improving patient and QTC treatment experiences, which is exactly what we are doing.

With that, I'll now pass the call to our Chief Financial Officer, Joe Vazzano, to discuss our financial results.

Joseph Vazzano

Thanks, Madhav. Let me start by reviewing the reporting changes we're making to provide maximum transparency and align with standard commercial stage practices. We will anchor future quarterly disclosures around completed operational achievements, specifically patients treated during the quarter and net revenue recognized. Consequently, going forward, we will report treatment activity solely within the designated quarter.

Before reviewing the financial results, I would like to remind everyone that you can find additional details for the quarter ended June 30, 2026, in our most recent Form 10-Q. Starting with the statements of operations. For the quarter ended June 30, 2026, Abeona reported net ZEVASKYN revenue of $11.4 million, representing a quarter-over-quarter increase of 31% or $2.7 million compared to $8.7 million in the first quarter of 2026. While 5 patients were treated with ZEVASKYN during the second quarter of 2026, we recognized revenue for 4 treatments as 1 batch had cell yield that was below the thresholds for revenue recognition.

Research and development expenses were $5 million for the second quarter of 2026 compared to $9.6 million in the first quarter of 2026. R&D expenses in the first quarter of 2026 included a one-time upfront cost of $7 million for in-licensing ABO-701. Selling, general and administrative expenses were $15.8 million for the second quarter of 2026 compared to $19.5 million for the first quarter of 2026. The decrease primarily reflects fewer engineering runs and less manufacturing training costs in the second quarter of 2026.

We reported a net loss of $20.2 million or a loss of $0.35 per basic and diluted common share for the quarter ended June 30, 2026. Net loss for the first quarter of 2026 was $17.1 million or $0.30 per basic and diluted common share. As of June 30, 2026, we maintained a strong balance sheet with cash, cash equivalents and short-term investments totaling $146.8 million. Our focus remains on disciplined capital allocation as we drive toward a sustainable cash flow positive business model, which we believe is achievable by maintaining a consistent cadence of patient treatments.

And with that, I will pass the call back to Vish for additional remarks before opening the call for Q&A.

Vishwas Seshadri

Thank you, Joe. In closing, we're proud of the dedication shown by our commercial, medical, manufacturing and quality teams, and we look forward to bringing ZEVASKYN to many more families. While we continue to learn to overcome the unique launch challenges associated with the logistically complex product delivery, each learning helps us lay a strong foundation to deliver sustained long-term value to both the RDEB community and our shareholders.

With that, I will hand the call back to the operator to open the line for your questions.

Operator

[Operator Instructions] Our first question is coming from Maury Raycroft of Jefferies.

질의응답

Unknown Analyst

This is [ Amin ] on for Maury. A couple of questions from us. First on -- you previously mentioned 1 patient per month per QTC is a reasonable near-term cadence. Just wanted to know when do you expect your existing QTCs, more specifically the leading ones like Lurie and Stanford to get there? And then I have a follow-up.

Vishwas Seshadri

Thank you, Amin, for that question. Yes, I think Madhav is best positioned to answer this question.

Madhav Vasanthavada

Thanks, Amin. I think, yes, we continue to hear about 1 patient per month from QTCs on average. And this is something that we will have once all of these centers are reaching a steady state. As we now know, earlier, Lurie and Stanford were the ones treating. Now we have biopsy from UTMB and CHOP has treated a patient. So, we're just waiting for other centers also to open up to be able to say when we reach a steady state. But once we are in the steady state is when we believe that 1 patient per month cadence is something that we continue to hear from the QTCs.

Unknown Analyst

Okay. And given you've now seen both a low-yield batch and an out-of-spec batch, how should we think about the long-term success rate for manufacturing? Do you view this as like isolated incidents? Or do you think this could be something that we will see in future as well?

Vishwas Seshadri

Thank you for that question. I mean, it's a little early. As you recall, our manufacturing experience in the clinical trials was a total of 11 patients treated, right? It's a very small data set. The -- and between the clinical trial as well as the subsequent clinical studies of Phase IIIb and our manufacturing experience to date, the low-yield batch is the first time we've encountered. So, up until this point, it looks like a low probability event. And there are several variables that cause such events that are related to variations in the incoming biopsy material. It could be related to the anatomic locations where biopsies are taken or a particular patient status or just the cellular yield that the growth characteristics that we derive out of any given biopsy. And given the limited experience, this is a rare kind of event that we've seen that the cell yield was low. And fortunately, for us, whatever sheets were manufactured were used for patient treatment. It's just that it's below the threshold of billable unit.

Having said that, we continue to -- we're running a lot of process science on every manufacturing run that we conduct. And hopefully, with enough experience, we'll be able to point towards positive reasons why this may happen and how we can improve upon that. But it's very hard to predict what such ratios could be. And since you asked about the out of spec, just wanted to take the opportunity to also mention what it was about. You may recall that there was one test that we never had in clinical development, which is the identity test which relates to the Pan-CK marker expression on keratinocytes. And we -- since there was no clinical experience, the way in which thresholds or specifications were set for this test was based on 6 samples of 5 being healthy volunteers and 1 frozen RDEB samples that we had at the time of BLA review. This was not based on true GMP manufacturing run experience to set such specifications. And that was the test that failed. This has nothing to do with either the safety of the product or the potency of the product.

So, we are working with the agency to revisit whether the specifications that were set during the BLA review were appropriate or should we even relook at that, right? So, some of these things will take some time and more experience to get concrete numbers to put on what should be our assumed rate of nonbillable units. But if you look at overall numbers to date, for any autologous therapy that has been launched in the past, you will see such examples. And we'll continue to keep refining numbers and probabilities as we gain more experience there.

Operator

Our next question is coming from Stephen Willey of Stifel.

Stephen Willey

Can you remind us of the manufacturing yields that you're seeing in the commercial setting? I know you have the capacity for 12 sheets on a per patient basis, but what's the average number of sheets you've been able to manufacture for the patients you've treated thus far? And I guess, how does this differ, if at all, from the prior clinical trial experience? And I just have a follow-up.

Vishwas Seshadri

Steve, the manufacturing yields from our commercial experience are actually -- they are very favorable when you compare it to what the clinical trial experience was. You may recall that for VIITAL, our Phase III trial, the maximum number of sheets that were allowed to be put on patients was 6 per patient. And in reality, it was about 5 sheets across the trial. And right now, we are around 9 sheets average per lot, which is a pretty healthy rate compared to what our clinical trial experience was. And therefore, which is why we're calling this an anomalous or a rare event that you had a low yield. And of course, 12 is the maximum that we can supply, but we're learning from every batch and making sure that any indicators that tell us that you could have a certain type of yield, we're learning from that to adopt our process and put best practices in real time.

So, we're actually pleased by averaging 9 sheets, which is a pretty substantial body area coverage.

Stephen Willey

And then can you say what that low-yield number is that triggers your inability to not recognize revenue?

Vishwas Seshadri

Yes. Anything that is lesser than 4 sheets in a batch is a low-yield batch. So, that's really our threshold. So 3, 2 or 1 as per NDC is still on label, but it's -- for billing purposes, we will not recognize revenue for those batches.

Stephen Willey

Okay. And then just with respect to the pan-CK marker assay that you mentioned on the keratinocyte side, where are you now in terms of engaging the agency around, I guess, either changing that number with a larger sample size or widening the confidence intervals?

Vishwas Seshadri

Yes. We have had some interactions with the agency. The first thing was -- the first step was to make sure that we could treat the patient, which is why we had to go through some communications with the agency, and we were successful in treating the patient. And I think from -- we should have more updates on where we are with the revision of the spec by the next quarterly update because we're still gathering the type of data. We're confident that the data that we have from our manufacturing runs in the GMP setting now justifies a lower specification from real-world experience versus something that was arbitrarily set based on limited experience during BLA review. So, it's a TBD how quickly this can be implemented because there are some mechanisms that are beyond our control and have with the FDA. So that's all I have for you at this point in time, but we will update you as in our subsequent quarters on this particular topic.

Operator

And our next question is coming from Ram Selvaraju of H.C. Wainwright.

Raghuram Selvaraju

Congrats on all the progress made this quarter. I wanted to ask about kind of last-minute cancellations, arbitrary withdrawals of patients from the process of ZEVASKYN treatment and how often you see that specifically occurring? So this has nothing to do with failures in manufacturing or inability to qualify of that. This specifically has to do with patients being unwilling to ultimately go through the treatment process, what we might call the arbitrary attrition rate. Just maybe you could give us some sense of how often that occurs based on current experience.

Vishwas Seshadri

Thanks for the question. Madhav?

Madhav Vasanthavada

Yes. Well, so far, we have had 2 such events, right, as we mentioned, that has happened in terms of our record. So, it's hard to predict, but if you look at the willingness for these patients to undergo the procedures, there's definitely a very strong willingness. But it's -- some of these things are -- if they are not able to make it because of illness or some health deterioration reasons, then we are talking about moving the biopsy date to some other date. It's not that the patients don't want to or are just backing off of the procedure itself. So, I just want to be very sort of clear with that, especially coming out from this Debra conference and SPD that I mentioned, we were just so energized. Literally seeing the number of patients that we've engaged with who were at our booth who are talking about ZEVASKYN. Some of them had the concern about what does the biopsy look like and what does the procedure look like.

But we've had our people from the Strong Together Network who went through this procedure in clinical trials, sharing their own experiences, right? The product theater that we presented was also packed. We had room for more than 160 people, and there was a lot of interest in these product theaters to learn about the procedures and the outcome. So, even if patients are dropping out for health deterioration reasons, we have not seen that these patients saying, "Oh, I don't want ZEVASKYN." It's a matter of rescheduling the biopsy to another date. And when that happens, especially in a quarterly report like this, when we talk about the number of slots with the number of patients, we are going to have different numbers for that particular finite period of time. And that's really how this current model is.

So, we are not saying that there is a patient attrition kind of forever. We haven't seen that even with these 2 health reasons that we've talked about. And it's, therefore, what we reiterated our strategy. The more centers we have active, the more patients that are going through this process, the greater shots we will have a goal to be able to have these more number of patients treated in a given period of time. So, I just hope that offers a bit more clarity. I know you were asking about our ability to predict such movements, but it's hard to tell so far we've had 2.

Raghuram Selvaraju

And then with respect to maximizing patient accessibility and convenience. You said during your prepared remarks that at this point, I believe you said almost half of the addressable patient population has in-state access to a qualified treatment center. So, I was wondering if you could elaborate on this from 2 perspectives. Firstly, how necessary you feel it needs to be for a patient to have in-state access to a qualified treatment center? And secondly, in order for the company to be able to provide this to the majority of patients or, say, 80% of the addressable patient population, how large would the qualified treatment center network theoretically have to be?

Madhav Vasanthavada

Yes. Yes, great question. So, the first question, importance of having a QTC in state. Earlier, we were talking about the payer mix, right? So, one of the things here is when you have Medicaid, especially and when you have an in-state Medicaid patient, the access there is much faster relative to a patient traveling from an out of state and a physician needs to be enrolled in the host Medicaid state. So, it actually helps to have a patient in the same state where you have a QTC just from an access standpoint.

The way we are saying that you have about 40% of our addressable patients are in state is based on our claims data when you count the number of claims that we have seen for patients in these states divided by the total number of claims across the country. It's not necessary to have a QTC in all of the states, and we will never have such kind of scenario. We'll have so many QTCs because this is such a sided community, and we know patients travel from out of state. In fact, about, again, 40% roughly of the patient mix that a QTC has for some of our QTCs are coming from out of state. They are traveling 300, 400 miles away. And hence, we are dealing with leading EB centers.

So, to get to that like 80% kind of a number that you mentioned, we will still be able to get that. It's a matter of prioritization. Some of these in-state patients might get faster access as the centers are working to have clearance for out-of-state travels. So, far in the patients we have treated, as we mentioned on our prior quarterly call, we've actually had quite a few patients traveling from out of state already. So, that mechanism already exists for people to travel and get treated.

And then lastly, I was just wondering if you could just give us a sense of when you anticipate NTAP status to be reflected on 2 levels. Firstly, the revenue cadence and secondly, if you expect it to show up on the margin front? And if so, how?

Madhav Vasanthavada

On the revenue cadence, it really will depend on the payer of the patient. I mean, I think for Medicare beneficiaries because NTAP is going to really apply to Medicare beneficiaries, whether they are pure Medicare or dual eligible, sometimes you have patients that are Medicaid, Medicare. So, for those patients is where revenue actually is going to come in through. And in the absence of NTAP, these patients would have had really very limited access, if any. And now NTAP actually opens up that vital reimbursement for the centers. And then Vish, you have to.

Vishwas Seshadri

Yes. So, one more thing I wanted to add, Ram, about the NTAP status is it has 2 effects, right? The direct effect is, of course, for the 10% of our patient mix that is dependent on the Medicare reimbursement. So it's a small sliver of our TAM, so to speak. However, the fact that we've built through this clinical rigor and gotten that NTAP status for those patients is also going to have a halo effect with other types of payers on how they view the technology because you kind of have a validation here. So that is definitely going to make it easier for centers, even for other types of patients to get the paperwork done. So, we're hoping that, that will aid their payer negotiations and things like that.

In terms of -- you asked about the margin front. For us, it's not so much of a margin place more for the QTCs on are they going to be whole -- made whole. And that's where the NTAP plays a big role because currently for Medicare patients, as you know from the CAR-T world, without NTAP, it's a big P&L loss for a treating institution. And NTAP fills a big hole there. So that's what we hope will debottleneck treatment for some of these patients in these centers.

Our next question is coming from Kristen Kluska of Cantor Fitzgerald.

Kristen Kluska

So, you mentioned in your prepared remarks that you want to have more patients enter the top of the funnel in case some of these situations arrive. I guess, which parts or issues could having more patients at the top of the tunnel potentially mitigate? And then which ones would this disruption still continue?

Madhav Vasanthavada

Yes, I mean, I think it's top of the funnel. So, things that are outside of our control, Kristen, is where we anticipate that, that's going to help mitigate, right? So, for example, all of the topics we mentioned, if there is a movement of a biopsy date that needs to happen, if you have multiple patients across multiple centers that are aiming to have a biopsy, then that will help to offset and have more patients come through. And it's essentially, it's having more shots at filling those manufacturing slots, which are finite in number. So, that's really the whole purpose, plus also having more qualified treatment centers helps with the patient access, the travel, the amount of distance that they have to travel, these patients trust certain institutions, right, more than others. So, we, therefore, want to increase that footprint. We also want physicians and actually, we're already seeing that. We recently engaged at the SPD through advisory meetings and the cross-pollination of best practices.

The number of treatments, as we have more treatment centers come on board to bring the physicians together and have that cross-pollination is just helping greater dissemination of information. And that also helps with overall raising awareness and clinical conviction in ZEVASKYN. So, it helps on multiple fronts, and that's exactly what we are currently in the process of doing.

Kristen Kluska

Okay. Appreciate that. And given that some of these windows are very limited, is there -- like does it make any sense to do like patient screening when they come in for biopsies or anything, make sure that they're healthy? I know you can't prevent 100% of the time them from getting sick and potentially meaning to cancel, but can this mitigate it at all?

Vishwas Seshadri

Potentially, right, these examples that we gave for the 2 patients that had to cancel their biopsies happen very close to their biopsy. In fact, one was on the day of biopsy that they said, I can't travel to the site and very sick. And the other example was like a day or 2. You have that kind of close to the biopsy date last minute, it's very hard to make adjustments. Whereas if you have this information like 2, 3 weeks in advance, that's definitely something else and that's where to your first question, if you have more patients on the top of the funnel, you have more flexibility or shots on goal that you may be able to move some patients and adjust date. If you only have 1 or 2, those idiosyncratic examples will just take over, we don't have reaction time to make amend.

So, that's really where it is, and we'll continue to monitor and hopefully, they are all not last-minute cancellations, and we learned some ways to mitigate it as we go through more such examples.

Our next question is coming from David Bautz of Zacks Small-Cap Research.

David Bautz

So, my first one is just about kind of clearing up the revenue recognition. So, if I understand correctly, you said that 2 of the patients you didn't record revenue for, but I believe those 2 patients were still treated. So, is this a case where the company is just going to kind of incur the full treatment of manufacturing costs? Or is there going to be a chance to recognize revenue for those 2 patients at a later date, the former.

Vishwas Seshadri

We will not be recognizing revenue for those 2 treatments because that is our agreement, right? I mean whether it's a low yield or if it's an out of spec, we basically eat up the COGS.

David Bautz

Okay. So, the Q2 gross margins look like they were about 63%. So, as the manufacturing process becomes a bit more predictable, where do you see the normalized gross margin settling?

Joseph Vazzano

Yes. So, our gross margins are heavily dependent on the number of patients that get treated in a given quarter, mainly because most of our manufacturing costs are fixed. So, with higher volumes, then our margins will improve. And we think standard state would be probably about 85% to 90% once we reach full operating capacity.

David Bautz

Okay. Great. And then lastly, can you give any additional details on the patient funnel kind of where it stands today? How many patients use ID or even biopsy or treat in to QTCs? Any of those type of numbers would be really helpful.

Madhav Vasanthavada

Yes. David, I mean, definitely, patients are interested. We know that there are identified patients on our prior calls, we had mentioned about more than 100 patients that have been identified by their community physicians and QTCs that are considered clinically eligible. There are certainly multiple other steps, right, downstream steps about consultation and funneling these patients. So, that's all happening. I think for us, like we mentioned on this call, the -- really the rate-limiting step is at the qualified treatment center and advancing these patients through the treatment process. So, as that continues to happen, we continue to believe there are patients that are going to move through, especially in light of some of the more recent interactions we've had with patients and physicians. So, I'm not able to provide any particular numbers, but we see that movement happening.

Operator

[Operator Instructions] And our next question is coming from Fanyi Zhong of Oppenheimer.

Fanyi Zhong

This is Fanyi for Jeff Jones from Oppenheimer. Maybe a clarification question. When you indicated you had a low yield, so revenue was not recognized for 2 patients. Does that mean the patient is unable to receive any treatment or there is sufficient material for partial treatment? So, what happens in that scenario? And the second question is, do you have a view for how long for new QTCs to begin treating patients?

Vishwas Seshadri

Just wanted to clarify that the 2 cases where we did not recognize revenue were 2 different cases. One was a low-yield issue and the other one was an out of spec. They're slightly different in nature. But in -- just to be clear, revenue was not recognized for either of those, but the patient was treated. Whatever sheets we produced and provided to the treatment center, the patients were treated. So, they received treatment, and we're hoping that the patients receive the clinical benefit and that experience will grow with these treatments. But revenue has not been recognized and will not be recognized for those 2 particular treatments.

Your second question was about how much time does it take to activate a QTC and get to patient treatment. And we had previously indicated this is about an average 4 to 6 months, but then the problem is with averages are not useful when the variance is so high. And you have examples we just gave you today where CHOP was activated in May, and they treated a patient in July. So, that was a very quick turnaround, whereas we have had other sites that have 12 months since activation and not treated a single patient. So, just because of this variability, it's very hard to predict. And the reasons are manyfold. It has got to do with the types of payer mixes in certain states and the paperwork that patients have to go through and various such factors. So, it will take us a little bit more time to try to thematize and put any numbers to what is a reasonable time that you can expect that a site will take between getting active and treating a patient. However, we are learning from these experiences and the more recent activations that we're seeing, sites are already talking to patients and trying to line up every part of the process that can be pre-lined up before even activation. So, that is something that we're seeing sites starting to do, but we'll have to wait and see how much that accelerates this time period.

I hope that answers your question?
