Speaker 2

Thank you, Carlo, and good morning, everyone. This has been a monumental period for Seres. Indeed, based on the progress we have made developing a microbiome therapeutics as a new medical category, Seres was recently nominated as a member of the TIME 100 Most Influential Companies for 2023 within the PIONEERS category. We are proud of the recognition, but more importantly, we are glad to now be making a positive difference in patients' lives with the recent approval of our first microbiome therapeutic. On April 26, we were thrilled to announce that the FDA approved Voust indicated for the prevention of recurrent C.

Speaker 2

Difficile infections in adults following antibiotic treatment for recurrent CDI. We believe VAST has the opportunity to transform how patients with recurrent C. Diff infections are managed, providing a new meaningful therapeutic option for patients facing this disease. In addition, We were very happy with the label that we received, which includes all adult patients with recurrent CDI, including those with the first recurrence. We are now working to commercialize VAST alongside our collaborator Nestle Health Science.

Speaker 2

VAST has been available since early June And we're pleased to report that preliminary uptake has been highly encouraging with healthy product demand coming from a broad set of healthcare practitioners and across the recurrent CDI patient pool, including in patients with their first recurrence. Terry will provide more detail on launch progress shortly. The successful commercialization of VAUST is our top corporate priority and the clear focus of our organization. Over time, we expect that VAST will provide tremendous benefit to patients and in turn, we anticipate this therapeutic will represent an important Financial Driver 2 series. As we commercialize Voust, we continue to expand our drug supply in collaboration with our manufacturing partner Resipharm to enhance future supply capacity.

Speaker 2

Furthermore, our collaboration with Baxdara also continues to move forward And we anticipate that Baxera will begin to produce commercial drug product next year for release in 2025 as the VAUS market continues to expand. While executing the VAUSQ launch, we also made meaningful progress with our earlier stage pipeline. In May, we reported highly promising Phase 1b Cohort 1 clinical data from our SER-one hundred and fifty five program. This cultivated microbiome therapeutic candidate is designed to prevent infections and or GvHD in patients undergoing HSAT. Initial data may support our therapeutic objective of reducing serious enteric infections, resulting bloodstream infections and GvHD in this medically vulnerable patient population.

Speaker 2

The SER-one hundred and fifty five study continues to enroll And we anticipate top line clinical results from the placebo controlled portion of the study encompassing Cohort 2 in mid-twenty 24. I would like to pass the call now over to Lisa.

Speaker 3

Thanks, Eric. I'll begin with Voust, a product consisting of a consortium of firmicutes bacteria in their spore form. This therapy is designed to facilitate restoration of the Biome and thereby reduce the risk of future recurrences of C. Difficile infections. Importantly, the indication we received with the FDA approval is for the broad population of adult recurrent patients.

Speaker 3

Faust has a straightforward oral dosing regimen of 4 capsules once a day for 3 days following antibiotic treatment and use of a laxative to remove residual antibiotic from the GI tract. Most is stored in the original packaging and has no refrigeration requirement. The full label is available on VAUCE's website at voust.com. To briefly recap, the VAST approval was supported by remarkable clinical data from 2 Phase 3 studies. Our placebo controlled ECOSPOR III study demonstrated that approximately 88% of patients did not experience a recurrence at the primary 8 week endpoint compared to 60% in the group with antibiotics alone.

Speaker 3

We also observed durability of response out to 24 weeks. OST was well tolerated and patients administered the drug had no serious adverse events or deaths that were attributed to study drug. Recurrent CDI is a serious disease that often results in hospitalization and can even lead to death. There are an estimated 156,000 recurrences in the United States per year and at least 20,000 deaths due to C. Diff infections.

Speaker 3

Patients suffer debilitating symptoms such as frequent diarrhea, which prevent them from conducting their normal daily activities And these symptoms significantly lower quality of life. We, along with our Nestle Health Science colleagues, continued to present and publish VAUST clinical results to educate the medical community about recurrent CDI and VAUST. We provided support for our continuing medical education event at the American College of Physicians Annual Congress in April, and we participated in the Digestive Disease Week Annual Meeting in May. Interest in VAUST at the conference was extremely high And during KOL engagements, we continue to observe significant levels of enthusiasm about the potential to use Vauce to stop the cycle of recurrence of CDI ineligible patients. Moving now to our new SER-one hundred and fifty five results, which we previously discussed in detail.

Speaker 3

The medical literature supports a strong connection between pathogen domination and lack of diversity in the GI tract with the endpoints of infection, graft versus host disease and mortality in patients undergoing ALLO HSCT. SER-one hundred and fifty five is an oral, investigational, cultivated microbiome therapeutic designed to prevent enteric derived infections and resulting bloodstream infections as well as to induce immune tolerance responses to reduce the incidence of GvHD and particularly severe acute GvHD in patients undergoing ALLO HSCT. The development of SER-one hundred and fifty five is supported by strong exploratory proof of concept data from the SER-one hundred and nine ECOSPOR III study, which showed that SER-one hundred and nine administration resulted in the decolonization of gut pathogens beyond C. Difficile, including bacteria carrying antibiotic resistance genes. These data have been previously reported at various conferences.

Speaker 3

Allo HSCT patients are at high risk of Enteric derived infections and acute GVHD. These adverse events are frequently seen in the 1st 100 days following the procedure. This is a period when the patients' microbiomes are highly disrupted from numerous factors, including antibiotic treatments and chemotherapy regimens and their immune systems are severely compromised. In May, We announced initial safety and pharmacology data from study Cohort 1. Based on these data, A favorable tolerability profile was observed with no serious adverse events attributed to SER-one hundred and fifty five administration.

Speaker 3

Pharmacology data showed that bacteria in the SER-one hundred and fifty five consortia engrafted, populating the GI microbiome with a magnitude and kinetic profile consistent with expectations based on prior clinical results from other Seres microbiome therapeutics. Importantly, we observed that the cumulative incidence of domination with bacterial escaped pathogens was rare and observed at substantially lower incidence rates than observed in a reference population of allo HSCT patients. These are specific pathogens known to be associated with the risk of enteric driven bloodstream infections and other downstream consequences such as GvHD in patients receiving allo HSCT. Enrollment is ongoing in Cohort 2, which incorporates a randomized, double blind, placebo controlled design to further evaluate safety and engraftment as well as clinical outcomes. This portion of the study will enroll approximately 60 subjects administered either SER-one hundred and fifty five or placebo at a 1:one ratio, And we anticipate obtaining Cohort 2 study data in mid-twenty 24.

Speaker 3

And with that, I'll now turn the call to Teri.

Speaker 4

Thank you, Lisa. I'm pleased to report that along with our collaborators at Nestle Health Science, we are making great progress in the early days of the VALS launch. As Eric mentioned, we are highly encouraged by the magnitude and breadth of HCP demand that we have seen. This demand is consistent with our understanding of the enormous need for better options to prevent RCDI and the

Operator

enthusiastic reception

Speaker 4

that the profile of ALKS has received since the release of our first Phase 3 data nearly 3 years ago. The performance we've observed also confirms that our commercial strategy, knowledge base and launch execution are setting us up for success. We have been very focused on 4 areas during the early launch period: scaling our HCP education efforts Creating a Positive Customer Experience, Establishing Payer Coverage and Optimizing Hospital Outflow. First, I'll describe our HCP education efforts. Immediately after FDA approval of VAST, the Nestle customer facing field teams were quickly trained and deployed.

Speaker 4

The field sales teams have been promoting VALST and generating HCP demand since May 2, several weeks before product became commercially available in early June. As a reminder, the 2 Nestle field sales teams are comprised of 150 gastroenterology representatives and a 20 person hospital and infectious disease focused selling team. We were also fortunate to have the DDW conference that Lisa referenced earlier in mid May right on the heels of approval. We had a significant presence at that key gastroenterology conference, including a highly attended product theater and a large well manned booth. The reaction to the profile of valves continues to be enthusiastic and positive.

Speaker 4

HCPs consistently mentioned the impressive efficacy and are encouraged to finally have a scalable, highly effective option that meets their number one unmet need in RCDI, preventing recurrence. As a result of our education efforts, we have observed the following magnitude and breadth of HCP demand as reported to us by Nestle Health Science. Early demand is broad across HCPs and patients, which is something we are very pleased to see. Importantly, We are seeing use across the recurrent patient pool, including demand in patients experiencing their first recurrence. The HCPs are choosing these patients as their very first patient for VALC is highly encouraging And you may recall that this is the largest patient pool within recurrent CDI.

Speaker 4

We are seeing utilization across a broad HCP audience and received prescription enrollment forms from over 480 unique prescribers as of July 27 with approximately 70% from for neurology and the remainder from other specialties. There is also a group of VAS prescribers who were not on the field team's call list, which is an indicator of the high unmet need and strong awareness in the provider and patient communities. Finally, Of the more than 400 HCPs that have prescribed Vals, 78 have prescribed Vals to multiple patients in their practice. This early depth of prescribing is a very positive sign given the moderate CDI patient volume, which typically exists at the individual HCP level. The second area of focus is providing a positive experience for patients and providers.

Speaker 4

Our valves Voyage Hub is a critical component of our commercial effort and provides a robust high touch experience including treatment and financial support. The Vals' Voyage team has been diligently working to convert patient enrollments into new patient starts. As with any new branded product, during the early launch period where payer policies are not in place, the prescriber must navigate the medical exception process. Our team is highly skilled at supporting providers and patients as they seek approvals for VAST, but in the event that it takes longer than the treatment window for VAST allows, We offer a free drug option for eligible patients. This is one of several financial assistance programs we are providing in this early launch phase And we are seeing expected utilization of our patient assistance programs.

Speaker 4

For example, approximately 43% of the 282 new patient starts were dispensed via our free drug programs. Our 3rd focus area is engaging payers to build coverage so that each patient who can benefit from VALF has access as quickly and efficiently as possible. The Nestle payer field team continues payer engagement, building on the extensive pre approval information exchange efforts executed during the year prior to approval. The team is making progress and is prioritizing the most important stakeholders, including the 3 largest PBMs to reinforce the compelling value proposition for VAST. We expect to see coverage policies issued as we move through the second half of this year.

Speaker 4

During the early launch period, We are seeing approximately 57% of our 282 new patient starts reimbursed through the patient's drug benefit. Finally, the hospital selling team continues its efforts to enhance hospital outflow and we believe these efforts will begin to bear fruit later this year into 2024. On a related note, last week, CMS issued their final rules for inpatient reimbursement for 2024. Included in this was the approval of a new technology add on payment or NTAP for Vauced when used for patients treated in the inpatient setting. The result of this is that hospitals will receive extra payment for any Medicare patients treated with Vals in the inpatient setting next year.

Speaker 4

We are pleased that Vals has received this additional payment from CMS. CMS notes in its final rule that the agency considers VASCE to be a substantial clinical improvement over existing technologies and that they see the importance of the technology in restoring the gut microbiome. We know that the proportion of patients who would receive Valsd in the inpatient setting is smaller than our outpatient opportunity and we do not expect that the NCAP will result in a significant number of additional vialysis patients in the near term. However, for these patients who are undoubtedly among the sickest, We are pleased that CMS has addressed the financial barrier for a hospital that chooses to use a therapy that Medicare has recognized as a substantial clinical improvement. We believe that over time, the NTAP approval could result in an additional inpatient utilization.

Speaker 4

In summary, we are highly encouraged by these early results. We, along with our collaborators at Nestle Health Science, will continue our focus on HCP CP education, customer experience, payer coverage and hospital outflow, and we expect to see continued acceleration of demand, progress success on the payer front and optimization of the provider and patient experience as we move through the coming quarters. Now I'll turn the call over to David to cover our financials for the quarter.

Speaker 5

Thank you, Terry. The details of our Q2 financials are included in the press release issued this morning. So I won't reiterate all the figures here. Seres reported net income of $46,600,000 for the Q2 of 2023 as compared with a net loss of $64,700,000 for the same period in 2022. The net income in the Q2 of 2023 was primarily due to the $125,000,000 milestone received from Nestle upon FDA approval of VAUS.

Speaker 5

VAUS Net sales for the partial commercialization period during the Q2 was $1,600,000 and based on 105 units of VAU sold during the period. The net sales reflect estimated gross to net reductions of 15%, primarily due to returns reserve, prompt payment discounts and patient co pay assistance. This gross to net reduction is an estimate based on certain assumptions and limited information will be refined over time as additional information becomes available. As Terry mentioned, we are actively engaged with the 3 largest PBMs and as a result, the 2nd quarter gross to net reductions do not reflect any discretionary payer contracting. Once VAUST became commercially available in early June, we started sharing equally with Nestle in the commercial profits and losses.

Speaker 5

Vau's profits and losses are determined based on Vau's net sales, cost of goods sold and sales and marketing expenses. The total Vau's loss in the 2nd quarter, in other words, from when VAUCE loss became available in early June

Speaker 6

to June 30

Speaker 5

was $4,300,000 and our share of that was 2,100,000 This amount, our share of the VAS loss for the Q2 is included in our P and L in the operating expense section as collaboration profit or loss sharing related party. We are responsible for supplying bounced inventory to Nestle. We built up sufficient levels of supply in anticipation of launch and we are continuing to produce VAS in support of the launch. In the near term, we expect to receive payments from Nestle related to their valves supply purchases and in the future we expect a steady pattern of purchases by Nestle to meet market demand. For example, during the Q2, Nestle purchased $7,600,000 of Vowel supply from us and we received the payment related to this purchase in the 3rd quarter.

Speaker 5

As of the end of the second quarter, we estimate that there was less than 2 weeks of vast inventory in the channel at the specialty pharmacies based on forward demand, which is typical for this stage of a launch. Following the approval of VAUST, commercial manufacturing costs will no longer be recognized as R and D expenses in our P and L, but instead will be capitalized and recognized on our balance sheet as inventory. Because the commercial manufacturing costs are now being capitalized, we expect Our total R and D expenses will decline going forward. For additional context, our Q2 2023 financial results Reflect the total R and D expenses of $47,000,000 of which approximately $11,000,000 was voused commercial manufacturing costs incurred prior to FDA approval. Seres ended the Q2 of 2023 with $229,500,000 in cash, cash equivalents and investments as compared with $181,300,000 at the end of 2022.

Speaker 5

In June, we received $125,000,000 milestone payment from Nestle associated with the FDA approval of VAUS. In April, we announced We had entered into a new $250,000,000 senior secured debt facility provided by Oaktree. We drew the first tranche of $110,000,000 at closing And after retiring our previously outstanding debt and deducting fees and expenses, the net proceeds to us were approximately $50,000,000 This debt facility has 3 additional tranches available, which are comprised of 2 tranches of $45,000,000 each based upon the achievement of certain applicable valve sales targets and an additional $50,000,000 will be available to us at Oaktree's discretion to support potential future business development activities. We remain highly disciplined with our cash deployment and we are prioritizing the successful commercial launch of VAST and the development of SER-one hundred and fifty five. Examples of actions taken in areas that we are pursuing to reduce costs and drive efficiencies include, We closed one of our 3 donor collection facilities supporting VOUS manufacturing, thereby reducing costs without impacting our ability to meet anticipated market demand.

Speaker 5

This closure was enabled by Baust's 3 year shelf life as well as operational efficiencies related to the production process. Also, our centralized donor screening lab opened in the Q2, allowing us to in source donor medical testing, which is expected to result in future cost savings. We are also actively consolidating office space and seeking to reduce our footprint, which enables us to be more efficient and save costs. And as we are allocating our resources in order to generate the greatest returns, we have reduced our headcount from the beginning of the year in part driven by the closure of our donor facility that I just mentioned. These are just some of the actions we are taking in areas we are exploring.

Speaker 5

We are committed to further reducing costs and to share additional updates with you. I'll now turn the call back to Eric.

Speaker 2

Thank you, David. This is an exciting period for Seres as we are now commercializing VAUST, the first ever FDA approved orally administered microbiome therapeutic. The launch is in its early days and we are very pleased with the initial commercial results. Since obtaining The Phase 3 ECOSPOR III data in 2020, we believed that we had the opportunity to help form how individuals with recurrent CDI are managed and we are pleased to see the early signs of this transformation occurring in the medical community. Over time, we are optimistic that VAST uptake will continue to accelerate and we expect that over time this product will become an important financial driver for Seres.

Speaker 2

We are also very excited about the progress we are making with SER-one hundred and fifty five and the data we have shared during the quarter. We are hopeful that the initial data that we have seen will translate into meaningful clinical results And we are looking forward to providing a robust clinical data set from Cohort 2 next year. Before I close, I'd like to touch upon the momentum that we continue to observe within the scientific and medical communities regarding the microbiome and its relationship to serious infectious diseases. Last year, the NIH hosted a workshop on the topic to advance research Into the medical significance of GI pathogen abundance. At the upcoming IDWeek conference, a symposium is being held on the establishment of pathogen decolonization as a surrogate for infection risk.

Speaker 2

The validation of this link would be highly valuable to Seres in supportive of our microbiome development efforts. We have previously discussed our own clinical results linking GI microbiome health with the risk of CDI recurrence and we are confident that over time the state of the microbiome will be more clearly linked with the risk of other serious infections. Importantly, this would have positive development, regulatory and commercial implications that could be highly advantageous to our platform and our ability to develop and market new therapeutics. This is a topic of great interest to our company and we look forward to discussing these concepts in-depth in the future. With that, I will conclude our remarks and open the line for questions.

Operator

Thank you. The floor is now open for your questions. We'll pause for just a moment to compile the Q and A roster. Your first question comes from the line of Joseph Tham with TD Colon. Your line is open.

Speaker 6

Hi there. Good morning. Congratulations on the launch and thank you for taking my questions. Maybe the first one, can you talk a little bit more on maybe the current timing Between receipt of a prescription enrollment form and a new patient start, maybe ask another way, kind of what proportion of those prescription enrollment forms Mentioned in the press release, do you expect will turn into new patient starts, I guess, over the next kind of quarter here, especially as it relates to the treatment window That allows. And then it's great that you're seeing interest across the refractory recurrent Seres environment.

Speaker 6

Are you seeing kind of equal ease In getting this therapy to patients, regardless of kind of where they are in their treatment journey. Thank you.

Speaker 2

Joe, good morning and thanks for the questions. I'm going to ask Terry to comment on the timing or evolution of the script and then the second is access across different recurrence.

Speaker 4

Sure. So I would start by saying that the vast Majority of patients that are seeking access to Vals today and going through the medical exception process are coming through. So we're being successful in the vast majority of those cases. It's important to note, when you look at the enrollment forms versus the new patient starts that we've seen new demand for new patients building over time, Right. So a lot of the enrollment forms that we're getting are more recent versus from May, for example.

Speaker 4

So the HUB It's been very, very busy, as I mentioned in my prepared remarks, turning those enrollment forms into new patient starts. But the demand has been building over time as you would expect with any launch. So I would expect as we move forward, we'll be accelerating the transition or the conversion of enrollment forms to new patient starts as you would expect. So we feel like we're being very successful early on and this speaks to the investment that we made in selecting the right partners in terms of hub provider, but also specialty pharmacies and making sure that we provided and invested in a very high touch robust patient experience. So we're seeing this pay off for us now early on in the launch, and we would expect that to continue over time.

Speaker 4

With respect to where the patient is in their recurrence journey, whether they're 1st, 2nd or 3rd, Really the determinant for us in terms of how we are fulfilling the physician demand is where they are in the antibiotic prescription, right? We are deploying our selling teams and making sure that we educate providers that they need to write Faust at the same time as the antibiotic to provide the maximum time in the treatment window to fill the prescription. So we do feel like those education efforts are paying off, but it will continue to take time. So that's the reason why we forward the voucher program as one of our patient assistance programs. At such a point in time where the patient is reaching the end of their antibiotic regimen And we haven't been able to get Vals through the medical exception process.

Speaker 4

It will trigger the offering of free drug. So we feel like we have the right tools in place and the right support and assistance in place to ensure that we are continuing to translate our physician demand into new patient starts. Anything you want to add, Eric?

Speaker 2

No, I think you covered that. I guess, Jo, for me, To Terry's points, we're seeing the demand, which I think is 1st and foremost, we had hoped to see and we are seeing the pull through including first referring patients. So overall, very encouraging.

Speaker 6

Perfect. And then maybe just one quick follow-up on more of the financial component. I guess, as it relates to closing 1 of those 3 donor facilities and then opening that central screening facility, I guess, What sort of scale should we expect on cost savings from that? And is that more of a Q4 kind of savings in the 2024? How should we think about that?

Speaker 6

Thank you.

Speaker 2

Yes. Maybe Debbie can comment, Joe. I mean, as far as the donor facility, there's Both a component of the facility itself, we will seek to sublet the space. There's approximately, I think it's 18 FT feet feet feet feet feet feet feet feet feet feet feet feet feet Es. The savings will be more of a 2024 item.

Speaker 2

We may see some pieces of it at the end of 2023. But keep in mind, there'll be a period cost savings as well as efficiency That will eventually roll through into COGS and maybe David can comment further including on the CLIA lab.

Speaker 5

Yes, That's exactly right. I'd look for savings to be realized in 2024 going forward. And I think also, as it relates to donor testing, there's a ramp up there As our volumes increase, so I think one would start seeing that in 2024 and beyond. Perfect. Thank you very much.

Speaker 2

Thanks for the questions, Joe.

Operator

Our next question comes from the line of Edward Tenthoff with Piper Sandler. Your line is open.

Speaker 7

Great. Thank you very much and congrats on a strong start with VAST, really exciting and I know it's an important product. So a couple of questions, if I may. Firstly, just kind of a housekeeping question and maybe a little bit early. But with the cash on hand, Are you able or did you and maybe I missed it, provide guidance in terms of what kind of runway that is with the milestone in the new And then, as it comes to gross to net, do you anticipate that 15% to So up or down or what do you think we should be expecting in terms of price?

Speaker 7

And again, my congrats on the launch.

Speaker 2

Yes, Ted, good morning and thanks for the questions. I'll ask David to comment on the runway and Terry to comment on gross Annette or maybe David and Terry, I think the answer to the second one is yes, we do expect it to go up, but they can provide better perspective or more fulsome perspective. So So David on the cash.

Speaker 5

Yes. Thanks, Ted. So as we discussed, we ended the quarter with approximately $230,000,000 in cash, cash equivalents investments. We have not provided runway guidance. I would just say we are Focused on, as we talked about, opportunities to reduce our spend going forward As well as we think there's tremendous opportunities to generate value as it relates to the VAST launch and progress there.

Speaker 5

On gross to net, as we talked about, Q2 gross to net was 15%. We're not providing projections at this juncture. And as we indicated, the gross to net in the second quarter does not include any discretionary payer contracts at point in time. So let me turn it over to Terri for additional color.

Speaker 4

Sure. So it's important to understand what's in the 15% and what's not. So This is comprised of what it takes for us to get product to patient, right, and through the channels, so specialty pharmacies, distributors, so on and so forth. And It also contains estimates for our co pay assistance programs as well as mandatory rebates Medicaid and government programs, so on and so forth. What it does not contain, as David shared, is discretionary rebates.

Speaker 4

Discretionary rebating is one tool that we have to ensure that We have broad robust patient access, but I would also kind of counter that by balance it by saying that Vals has an incredibly robust value proposition supported by its clinical profile, but also by the fact that these patients are incredibly expensive. And if you use Vals early on in the treatment paradigm and we are seeing use there, you can achieve significant cost offset. So we're going to be very judicious and thoughtful regarding how we leverage discretionary rebating moving forward. And as we do move forward through the following quarters and have more color to share, we will do that.

Operator

Next question comes from the line of Tessa Romero with JPMorgan. Your line is open.

Speaker 8

Great. Thanks so much for taking our question. Hi, Eric and team. So for the 3 largest PBMs, Are you able to give us a sense of cadence of the expected decisions here based on the cycles? On the call, you noted that 43% of your 282 new patient starts were dispensed via free drug program.

Speaker 8

Just trying to get a sense of how you expect this to trend in the next couple of quarters here? And then Second question for me is, can you give us a sense of what the new patient starts are looking like month to month qualitatively? Any trend you'd point out between June July. Thanks so much.

Speaker 2

Tess, good morning and thank you for the questions. I'm going to ask Terry to comment on both The PBM, cadence over time and then kind of anecdotally, what are we seeing? And maybe I'll add some comments on the end.

Speaker 4

Sure. Good morning, Cass. With respect to the PBM cadence, those conversations are Actively in progress, I would say, and really begin, even pre launch, right, with the preapproval information change. We made sure the payer field teams were covering those very, very important customers and ensuring that they understood the data and where we thought Vals was best utilized in the value proposition. So they're really going in now to reinforce those historical conversations that they've had And spend time with the clinical teams and then you typically enter this phase of additional discussionsnegotiations And that's really still to come.

Speaker 4

So we see these conversations playing out over the rest of the year, and I look forward to sharing more as we have more to share. Free drug you asked about. The free drug utilization is in line with the estimates that we had pre approval. So we're pretty pleased about that. This is an important tool for us to provide a positive patient and provider experience very early on, and we feel like that will pay dividends to us later on with respect to demand.

Speaker 4

What I'll also tell you though, there are really 2 important components to the free drug program. 1 is the voucher program, which is triggered when a patient exceeds the treatment window, when we're trying to navigate the medical exception process with them. So this is something we anticipate it's a program really. We anticipate Working itself out of a job, if you will, to a large extent. As payer policies are issued and the prior authorization processes become more automatic, They'll become quicker and patients shouldn't need to leverage that program as much as they might today.

Speaker 4

The second element of Free drug is a more traditional income qualification path and we are seeing utilization of that program largely by Medicare patients today and We already we always knew that Medicare patients would have affordability challenges until the IRA takes effect. But in 2025, When the cost sharing provisions and benefit design changes for Part D as mandated by the Inflation Reduction Act, we would anticipate this being another program that we see decline. So hopefully that color helps.

Speaker 2

And maybe I'll just add test on top that in general, It's early. So we're certainly cognizant of the fact that it's early, but we saw strong demand. We saw it across HCP specialties, we saw it across recurrent CDI patient profiles, including first recurrence. So while early, we're really encouraged with what we've seen and we're excited to continue executing on the launch with Nestle.

Speaker 4

Yes. And we did see to your final question growth Month on month as you would expect. So we are seeing growth as we move through the months and the periods.

Speaker 8

Okay. Thanks so much for taking all of our questions.

Speaker 2

Thanks for the questions, Tass.

Operator

Next question comes from the line of Jeff Johns with Oppenheimer. Your line is open.

Speaker 9

Thank you very much and congratulations on a great quarter. With respect to valve sales, can you Comment on the how much of that $1,600,000 in 2Q are attributable to inventory build or channel stocking versus New patient starts. And the second question, can you provide any additional color to understand the profit share recorded versus revenue. Andy, how you see that trending moving forward? Thank you.

Speaker 2

Yes, Jeff, good morning and thank you for the questions. Maybe David and I can handle those 2. On the first, There is an initial purchase of inventory from Nestle, but in terms of Build or inventory build, I think David in his prepared remarks had a comment on how much was in the channel, Which is not that much. But beyond that, maybe I can just comment and Debbie can take it further. We didn't expect to see, we don't think we have seen Warehousing of patients, right?

Speaker 2

This is not a chronic disease. This is an acute disease. And The breadth of prescribers that we have seen, I think, suggests to us that, whereas we did hear a couple of anecdotes of Some of the physicians that we know well that had a number of patients on Vanc Tapir and they've been waiting for the moment that VAS would be available and switch some of those patients, That was really the minority of what we saw in this first period of launch. So I don't think that there's inventory that's really pushing this number. And maybe David can comment further in on the second question as well.

Speaker 5

Yes. Thanks, Eric. Yes, As we reported, 2nd quarter sales, dollars 1,600,000 was comprised of 105 valves units. Our estimation is at that point in time that represented less than 2 weeks of inventory in the channel at the specialty pharmacy. So, there is not a whole lot of channel inventory, and that would be our expectation going forward as well.

Speaker 5

I think your second question was about Vow sales versus the profit loss sharing. So what we reported the $1,600,000 those are the net sales of VAALC for the 2nd quarter That then generated a net loss of $4,300,000 which is shared fifty-fifty between Nestle and Seres. So our books Reflect that $2,100,000 to 50 percent of that $4,300,000 How that's going to change over time as Vowel sales increase, We are driving with our collaborating Nestle towards generating profitability as it relates to the VAST P and L. We think that's very much achievable. And if you think about the sales and marketing expenses, we have the we are Fortunate to leverage Nestle's infrastructure and capabilities and believe that we can commercialize Faust in a very cost efficient manner.
