Thank you, Greg. Hello, everybody. Thank you for joining us this morning. I'm pleased to update you on our continued progress, evolving from a clinical stage company to one with a significant commercial opportunity. Let me start with the highlight that everyone at Aviona is thrilled about. We achieved That's the most meaningful milestone yet in Aviona's history at the end of September with submission to the FDA of our biologics license application, or VLA, for Pradamagene zamycaracil, or PzCel, which was formerly known as EB101. PzCel is our investigational autologous Col7a1 gene corrected epidermal sheet for recessive dystrophic epidermolysis bullosa, or RDET. As a reminder, In clinical trials, a one-time application of PV cell had demonstrated wound healing and pain reduction for the toughest-to-treat large chronic wounds. Some wounds that were treated in our Phase I-IIa clinical trial remained healed after eight years. The sustained treatment effect we have seen is due to the integration of col7a1 transgene into the host genome during the transduction of patient keratinocytes ex vivo. Our BLA submission represents a critical step toward the potential approval of PZ Cell as the first therapy to provide instantaneous wound coverage and multi-year healing in RdEV wounds with a one-time application. I want to take a moment to thank many stakeholders who contributed to this milestone achievement, not just for Aviona, but for the whole RdEV community. From the patients, caregivers, and physicians, who participated in the vital clinical trial, the patient advocacy community, and the FDA for their level of engagement and constructive guidance in the months leading up to the pre-BLA meeting that occurred in late August. I also would like to acknowledge our entire submission team for their tremendous determination over many months to prepare the BLA. We recently completed our application orientation meeting with the FDA. where we overviewed our BLA and walked them through our clinical data. Our understanding is that this meeting is one of the last steps before the FDA decides on acceptance of the application for formal review. Regarding what we can expect next, the FDA's decision on whether the BLA review process can start is typically made during the 60-day window following submission, which in our case goes out to late November. With the BLA submission, We requested the FDA grant a six-month priority review. Under a priority review scenario, PZ Cell could be approved in the second quarter of 2024. I'll remind you that PZ Cell has been granted rare pediatric disease designation by the FDA, so upon its potential approval, we continue to believe that we're eligible to receive a priority review voucher, or PRV. It's permissible to sell PRVs And other PRVs have been worth approximately $100 million based on recent PRV transactions. Planning for the potential success of our VLA, our manufacturing team is focusing on supporting the VLA review process, preparing for pre-approval site inspection, and scaling up our internal capabilities and staffing for commercial launch. In the first full year of launch, we currently plan to supply PC Cell for up to 120 patient treatments or manufacturing cycles per year. Following launch, we will assess our longer term plan to further build up that capacity. We are excited about the prospect of transitioning to a commercial stage organization with Aviona's first product launch. However, it is important to note that PZ Cell will not be the first psychologist therapy launch for this leadership team, as Madhav and I will draw upon our previous launch experiences with Brianzi and Abekma. As Chief Commercial Officer, Madhav will oversee all aspects of commercial strategy, planning, and operations. His extensive and diverse leadership experience across sales, marketing, and market access Coupled with a strong track record launching autologous cell therapies with a heavy focus on customer experience makes Madhav the ideal candidate to lead the stage build-out of our highly focused, nimble commercial organization to maximize the potential commercial opportunity for PZ Cell. I'll now ask Madhav to talk about our near-term commercialization focus and launch preparations. Madhav? Thanks, Vaish. We are, of course, excited for the potential commercial launch of PgCell pending FDA approval. In terms of our commercialization approach, our near-term focus is simply on two main areas. One is to onboard and prepare five to seven high-volume EV treatment centers so that they can treat with PgCell upon approval. These centers already have the expertise in caring for EB patients and are geographically dispersed across the U.S., which would help make PZ cell treatment accessible for these patients. And two, working with commercial and government health insurance systems to ensure broad access for all eligible patients at a price point that captures the value that a transformative therapy like PZ cell might bring. We are happy with our progress so far on both these fronts. To elaborate further, in terms of site onboarding, shortly after our BLA submission, we conducted an advisory board meeting that was attended by eight well-respected physicians, PD physicians from across the U.S. We discussed not only the clinical data and the care coordination needed for surgical application of PD cells, but also For the first time, we shared some of the before and after images from several large wounds across multiple anatomical areas treated with PZ-Cell, as well as patient and caregiver testimonials about their experience with PZ-Cell in clinical trials. They're very encouraged by the physician's feedback, which included their suggestions on ways to operationalize PZ-Cell at treatment centers. We have received interest from these physicians to initiate easy-sell site onboarding discussions at their institutions, and we are very excited by it. With respect to the second focus area of payer engagement, we will continue to engage payers over the coming months to educate them about easy-sell and further assess the price potential. Early feedback from payers and hospital administrators supports positive coverage for PT cell and pricing in line with the value of a cell and gene therapy that provides instantaneous coverage for large wound areas and that demonstrates years of wound healing and pain reduction, even in the toughest to treat RdEV wounds following a one-time application. Furthermore, we hope that the sustained effect we see in our clinical trials on wound areas with a one-time application of PT cell could minimize the treatment burden incurred by patients and caregivers in continuously caring for their wounds day after day and week after week with current standards of care. Additionally, in speaking with our clinical trial patients and the advocacy community, we continue to hear enthusiasm for PZ-Cell. In fact, in our ongoing phase 3B trials, all three patients are repeat patients. who fully appreciate the involved nature of the procedure and have elected to receive PZ-Cell again for their previously untreated wound areas. We will continue to work with patient groups and make sure that the voices of the patients, the families, and the caregivers are well represented as we engage with the FDA and payers. Lastly, since our BLA submission, we have leveraged our network and have moved quickly to fill crucial commercial roles, including key account management, market access, and marketing, with proven biopharma veterans who bring additional launch and commercialization expertise with autologous cell therapies. Their contributions will be an important piece of our launch planning. We intend to further build out our commercial organization and infrastructure in a stage-gated manner aligned to BLA acceptance. Now I'll hand the call over to Joe to discuss our third quarter financial results. Joe?

Thanks, Manav. I would like to remind everyone that the Form 10-Q is available on our website. which is where you can get additional details on our financial results for the three and nine months ended September 30th, 2023. Starting with the financial resources on our balance sheet, we had cash, cash equivalents, restricted cash, and short-term investments of $54.1 million as of September 30th, 2023, including $25 million in gross proceeds from the registered direct offering in July of 2023. as compared to $37.1 million as of June 30th, 2023. Based on our current operating plan and assumptions, our financial resources remain sufficient to fund our commercial launch preparations for PZCEL and our business operations into the fourth quarter of 2024. In other words, our cash runway extends beyond the potential commercial launch of PZCEL and receipt of a priority review voucher. Research and development expenses were $7.1 million for the three months ended September 30, 2023, compared to $5.5 million in the three months ended September 30, 2022. Our spend on general and administrative activities was $4.2 million for the three months ended September 30, 2023, compared to $3.9 million in the same period of 2022. Net loss attributable to common shareholders was $11.8 million for the third quarter of 2023, or $0.48 loss per common share, as compared to a net loss attributable to common shareholders of $6.4 million, or $1 loss per common share in the third quarter of 2022. With that, I'll turn the call back to Vish for brief closing remarks before kicking off the Q&A session.

Vish? Thank you, Joe. I would like to close by reiterating what an exciting time this is for Aviona, for PZ Cell, and for the RDEP community. Based on our strong clinical data and enthusiasm from the medical community, we believe that PZ Cell could be an important potential treatment option for patients. With our BLA submission, we've demonstrated our ability to take a cell therapy product from research through clinical development. We are well positioned for potential market entry with extensive and diverse commercial and launch experience with pathologist cell therapies. We're looking forward to the anticipated momentum in the coming months as we both advance PZ cells through the regulatory process toward potential approval and continue executing our commercial readiness plan and ultimately to a potential U.S. launch of PZ cell. With that, operator, please open the Q&A session.

Thank you sir. At this time we will be conducting our question and answer session. If you would like to ask a question, please press star 1 on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star 2 if you would like to remove your question from the queue. And for participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. One moment please while we poll for questions. Thank you. Our first question is coming from Kristin Kluska with Cantor Fitzgerald. Your line is live.

Hi, everyone. Good morning. Thanks for taking the questions. I was hoping you could elaborate or speak to some of the work you're doing now for patient identification early on. And given that some of these patients may need two of the procedures, any chance of the prior trial participants, including Phase 1-2, being involved?

Thank you for that question, Kristen.

Before I turn it over to Mazav, I'll just provide my thoughts, and Mazav will elaborate. Just to reiterate, your question is around prior identification of patients before potential launch and how I think the Phase I, II, as well as I would say even the vital patients would benefit from a potential launch. We can even provide some anecdotes from our current experience. And it's not just the Phase 1-2 study and vital, but we are also having a Phase 3-B study that is going on for the 3-0-2 study where patients from both the previous two studies are coming for repeat treatment. So all of this augers well as we prepare for launch, but for the specific question of patient identification model, we'll take that. Yeah. Thanks, Kristen, for the question. I think the AdWords that we conducted recently was very assuring in that physicians continue to believe that these patients will require more than one therapy. So, as we have patients being identified and their awareness increasing with the topical gel right now with that is certainly one bolus of patients that we can look to bring on. We do know that there are patients in the Centers of Excellence who visit these centers for ongoing wound care management, whether it is infections or whether it is squamous cell carcinoma. And the longer the wounds are chronic in nature, the greater the risk for these infections to happen. So in speaking with physicians, you know, we already know that certain physicians are thinking about their patients who would benefit from PZ-cell and are thinking of identifying in their own minds. But as we get closer to launch, we will continue to formalize this analysis and gather more tangible based on claims analysis and where the patients are. to concretely find out, okay, what is the volume here we are talking about, so that we can queue them up in anticipation of approval.

Okay, thanks. And then, sorry, go ahead.

No, I wanted to check if that helps answer your question.

Yes, yes, very helpful, thanks. And assuming your timelines that you've laid out are a go, How quickly do you think you'll be able to have this in the commercial field?

So post-approval, similar to autologous therapies, you know, right after approval, we will look to do P&T approvals at these EBE treatment centers and then very quickly have medical policies in place from the payer's standpoint. So our estimation is we're talking about maybe a month to two months a ballpark to have these processes in place. So that would be our sort of a launch, if you will. And from then on, you know, we have the physician's ability to place an order for a PC cell. But our goal will be to have it as soon as we can post FDA approval.

Thank you so much.

Thank you. Our next question is coming from Maury Raycroft with Jefferies. Your line is live.

Hi, this is Yao Ong for Maury. Good morning. Thank you for taking our questions. Our first question is on the commercial opportunity. We think you recently said at conference that you estimate the peak sales to be about $500 million. What kind of assumptions went into that estimate, and what do you need to build in terms of infrastructure to reach that target?

Yeah, thanks for that question. In terms of the assumptions that went in, as we've indicated, for us, our ability to supply at the time of launch is around 120 patients in a given year. And we look to ramp that scale over time as soon as we have a few initial treatment centers, have the experience to, you know, provide, you know, PC cells, and then we estimate what the demand looks like so that we can increase the capex. For the peak sale, we have a projection of 500 patients in a year over, I think, around five-year time frame. So the peak sale we have projected there is with a 500 capacity over a period of five years and the pricing estimate we have also baked in is a seven digit price point. So these are the initial key assumptions and we expect these patients to come in both de novo patients the first time, as well as an average assumption that each recessive dead patient, given the large amounts of wounded area that they have, will require two such rounds of ED-101 treatment cycle. Yeah, and if I can just add, one of the reasons we will be triggering any capacity expansion after launch and the initial experience with the first centers of excellence that we onboard is that we get a good sense of what level we will need to expand the capacity. We're starting at 120 a year and let's say in a two year post launch scenario, should we ramp it up to 500 or 350 or 700? I think some of those assumptions will be validated once we start seeing that initial demand and trends. And for that reason, so what you're seeing as a peak opportunity of greater than 500 million is dependent on a capacity expansion in our assumptions. I hope that has given you some perspective there.

Got it. That makes sense. Thanks for that answer. Another one on commercial, we heard recently that Crystal reported about half of their scripts are actually from community doctors versus centers of excellence. Are you thinking about reaching maybe to some community doctors and get the initial steps done before patients are treated at centers of excellence? or how does that report or sort of surprising update change how you're thinking about your launch?

Yeah, so there are centers of excellence as well as community centers where these patients are present. For us, at the time of launch, we believe that patients who are at the centers of excellence will be ideal candidates to get this therapy. And over a period of time, we will look to expand outwards from centers of excellence, which are PZ cell, you know, trained centers, to the centers of excellence that don't necessarily have the ability to surgically apply with PZ cell, and then finally to the community centers. There are some 23 centers of excellence that we know of that see a lot of EB, our dead patients. And so clearly, we will look to educate these centers so that they are aware of the therapy and, you know, we could have the referral in place. So that's our approach. And we continue to work with patient advocacy groups. We have a strong partnership with multiple advocacy groups, DEVRA in particular. And given the nature of this patient community, we also anticipate a vast majority of these patients with self-referral. if they understand where these centers are that, you know, apply PC cell procedures. So that's going to be our approach. And so even though the patients are in the community setting, for a treatment like this, which is a one-time procedure for those wounds that they are suffering from, there is a strong appetite and there is a strong pull, versus if this were to be a chronically applied treatment, then yes, I think we would have to think hard, but here is where we feel the value proposition is very strong.

Okay, got it. Just one last quick question. The Phase 3 trial enrolled patients six years old or older. Do you think the label is going to have a minimum age of six, or how do you think about unmet needs in patients under six years old?

Yeah, that's a fantastic question. Yeah, thanks for that. It's going to be a dialogue that we will have to have the FDA. So if you look at body surface area, so this is a topically applied epidermal sheet. So dose is something that is differently viewed here. as a percentage of body surface area that we are applying these sheets. So, if you look at a small statured patient, let's say close to the six year old mark, and we've applied six to eight sheets. In fact, we've applied 14 sheets across the two studies on the same patient that's a seven year old. And so as a proportion of their body surface area, that's a huge percentage of coverage. So how the agency is going to view dosage is going to impact how they view a minimal age. Because the reason why the six-year age was selected as a minimum in our study was primarily the ability to report pain endpoints. understanding the wong baker scale which is validated for ages six and above so because we had an endpoint we had that restriction now does that mean you couldn't apply this therapy on a patient that is four years or three years old um that is you know up to the negotiation and we believe that with the currently ongoing phase 3b study dropping that age limit below that six years is also going to help build that experience so by the time we get approval This is something that's going to be locked in the late stages of review with the FDA. Our anticipation is that it's going to be beneficial for patients even younger than six years of age. But this is where the dialogue that's currently happening Among various types of positions, the plastic surgeons, as well as the specialist says, what is the age of a patient where we can safely have them follow best practices after application in order to immobilize these sheets because of patients move too much. The graph needs to take optimally, and how do we manage those patients that are younger than, let's say, 12 months old? I think these are all the types of questions we're currently answering to say, what is that age? But we believe that it's definitely applicable to much lower than six years of age. So more to come in the coming months on that topic.

Got it. Thank you so much for taking our questions. Again, I'll hop back in the queue.

Thank you. Once again, ladies and gentlemen, if you have any questions or comments, please press star 1 on your phone at this time. Our next question is coming from James Malloy with Alliance Global Partners. Your line is live.

Hello, this is Laura on for Jim. Thank you for taking our questions. So with you working on building a commercial organization for PZStyle, Have you also started the sales team hiring process yet? And, you know, have there been any challenges on getting members to join?

Thanks, Laura. To address your second question, actually, we have had no issues at all in bringing on talent so far. We've got the leadership team in place from a commercial side. We have the head of marketing, the medical team, operations person market access and key account management so we look to continue to scale the organization not we don't need a whole lot of team right because what we have been saying early on is that this is a therapy where a limited commercial infrastructure is what we require given the pull so that leads me to your first part of the question with regards to sales per se We don't anticipate having a sales team or a major sales team at launch because of the initial level of interest that exists in these centers. But over time, perhaps after the approval is when we may look to bring on sales teams to continue to educate the outdoor community that is out there. We will have a medical team in place, whether it's medical science liaison, and continue to educate and also have a key account managers who are going to be the point of contact at these treatment centers where PC cell will be placed. So that's our, you know, model that we will have, which is to focus on key account managers and medical teams.

Got it. And then also going back to Crystal Biotech, you know, they launched a for DEB. Comparing this to PZ Cell, what are your overall thoughts and what takeaways do you see for PZ Cell from this particular launch?

Our takeaway is that this is great to see the uptake of these products. For far too long, these patients have had no really therapeutic options. have been subjected to standard of care. The burden that they've had on treating their wounds has been just devastating for everyone. So we are happy to see the awareness picking up. We are happy to see that patients are getting motivated. The insurance companies are beginning to cover these patients. And that was our major takeaway from following what's happening in this space is that payers are beginning to clear up the access And I think what that means for is is the fantastic positioning because we are coming fast followers, which only helps a number one has raised the awareness for these patients and these physicians that there are therapeutic options coming into space. And number two for the paperwork and the. access clearance and, you know, genetic copy of genetic testing, so on and so forth, which is taking several weeks, by the time that PGSEL comes to market, you know, we will be in a better position. So, these are really the positive takeaways for us, and we continue to learn as we approach our approval timelines. And also, just not to forget differentiation, right? clearly from the physicians that all these therapies are going to be needed by almost all the patients because the approach is very different. The value proposition is very different and patients do have different types of wounds in their body and for the large wounds where that there's a lot of pain and you need instantaneous closure, the willingness to go for the big guns, if you may, like PC cells, is going to be there. So that's what we're learning, which is why a pent-up bolus of patients in centers of excellence is already kind of sufficient to take our long infrastructure over, which is why we're not investing on a big sales force because we know these patients already exist.

Understood. So just one last question from us. You've mentioned in the past the potential for PZ-file to be formulated, you know, either as a spray or to have different skin graft sizes used for the patient. So when might you look into trying to get these additional, you know, indications or administration methods onto the label?

Yeah, I think from a, from a perspective of life cycle management, this is this really we, we have to think hard whether it's even PZ cell that comes with the spray. It's probably going to be a whole new biological product. Clearly, there's some learning. I mean, we have been very disciplined in how to focus our finite resources. Our job with the PZ cell launch is not yet done as much as we're getting closer every day. So we have these ideas. I think some of the common unmet needs that we hear is can you make glove-shaped uh graphs for mitten deformities because hand surgeries are a big part of uh you know these patients legend and can you can you do that i think there's a lot of that unmet need and ask from the patient community for these products we're being careful that uh you know let's get pd cell launched let's um get the uptake and um we will be on our way for what improvements we can build but clearly that's going to be not EB101 but EB102. It's going to be a different product, but we are keeping our eyes and ears out to, you know, further understand the unmet need and design these products appropriately.

Got it. Thank you for taking the questions. Thank you, Laura.

Thank you. As we have no further questions in queue at this time, I would like to hand it back over to Mr. Seshadri for any closing comments.

Thank you. In closing, I want to thank our shareholders and other stakeholders who have listened to this call, and we'll talk to you again soon.

Have a nice day.

Thank you. Ladies and gentlemen, this concludes today's conference, and you may disconnect your lines at this time. And we thank you for your participation.
