Thank you, Marcy. Good morning everyone and thank you for joining us today. In the second quarter, we continue to build on the momentum from the first quarter of the year where we transition to a commercial stage company with the successful U.S. commercial launch of FYARRO, our albumin-bound mTOR inhibitor for advanced malignant PEComa.

Overall, I'm very pleased with the execution of our commercial team during the quarter. We saw strong net product sales of FYARRO of $3.4 million in our first full quarter post launch. And we are excited to see FYARRO reaching more patients through not only the academic centers, but also through continued adoption in the community setting.

Brendan will give us some more color on this in a few minutes. In terms of our overall pipeline progression, we are also very encouraged by the advances in our ongoing PRECISION 1 trial, our registration-directed tumor-agnostic study for Napserolomus in TSC1 or TSC2 alterations in solid tumors.

This trial has the potential to significantly broaden the future application of MAP's sirolimus across many different tumor types, including about 12,000 new advanced cancer patients on an annual basis in the U.S. alone. Loretta and our clinical team have been executing diligently on getting the PRECISION 1 trial up to speed as rapidly as possible.

While we are still very early in the enrollment of the PRECISION 1 trial and we continue to activate new clinical sites on a regular basis. We anticipate providing preliminary data on a meaningful number of patients in the first half of 2023. The rest, I will shed some more light on the conduct of the PRECISION 1 trial in a few minutes.

Additionally, we continue to evaluate the potential use of Napserolomus in a number of new clinical indications, either as a single agent on combination with other targeted therapies with the potential for new clinical programs as early as 2023.

During the remainder of 2022, we are focused on maximizing the clinical and commercial potential of FYARRO to further strengthen our ability to deliver therapeutic benefits to patients and create long-term value for stakeholders.

We aim to establish Aadi as a leading precision oncology company initially focused on the development of drugs that effectively target the mTOR pathway. With that I will turn the call over to Brendan to provide further details on our commercial performance during the quarter.

Brendan?.

Thank you, Neil and good morning everyone. As you heard from Neil Aadi had a great first full quarter of FYARRO sales. In the second quarter, we reached $3.4 million in U.S. net product sales bringing the total for the first 4.5 months since launch to $5.7 million while it is important to remember that we are still very early in the launch process.

Our commercial team is executing well in the market and we are encouraged with the uptake FYARRO across treatment settings.

As mentioned on our first quarter earnings call, we did see a significant bolus of patients in the first weeks after product availability some of which carried over into the second quarter as many patients successfully continued on FYARRO therapy.

In addition to that carryover, we were pleased to see steady product demand growth and new patient starts continuing throughout the second quarter. Insights from our recent launch tracking surveys show very strong brand awareness, message recall, product perceptions and intend to prescribe among those physicians who treat sarcoma patient.

We are encouraged by the increase in uptake and continued growth and adoption and as of June 30, more than 60 accounts that ordered FYARRO with a reorder rate exceeding 80% across all ordering accounts.

Adoption in the academic treatment centers continue to be strong and we are also very encouraged to see that 40% of ordering accounts since launch now represent those in the community treatment setting. Our market access team delivered broad patient access to FYARRO and in the second quarter, we continue to closely monitor payer metrics.

I'm happy to report that as of June 30 payers covering approximately 80% of commercial lives in the U.S. market have reviewed and adopted a formal policy providing coverage for FYARRO, which continues to surpass our initial expectations.

We were also pleased to report that as of July 1, the Centers for Medicare and Medicaid Services or CMS as assigned a permanent J-code for FYARRO, which further helps to streamline the product reimbursement process in all outpatient treatment settings.

This rapid payer progress combined with a robust suite of patient support resources available through our AadiAssist program has continued to provide strong patient access to FYARRO since receiving FDA approval last November.

We are looking forward to what will come in the second half of the year as we gain additional experience engaging with new clinicians and patients. I will now turn the call over to Loretta to discuss the progress of our clinical programs.

Loretta?.

Thank you, Brendan. In the second quarter, we've continued to see good progress in our ongoing in PRECISION 1 tumor agnostic trial as a number of open sites increases along with access to patients both in cancer centers of excellence as well as in the community setting.

We have continued to strengthen our R&D group with all functions now nearly completely staffed. This has enabled us to set up new trial sites more rapidly and facilitate efficient patient recruitment while providing appropriate trial oversight.

We continue to make significant progress towards our goal of opening the trial in at least 20 major cancer centers and upward of 120 treatment sites in the United States by the end of this year.

More than 15 individual major cancer centers have already been initiated, including most recently Memorial Sloan-Kettering Cancer Center City of Hope, The Barbara Ann Karmanos Cancer Center, Roswell Park Cancer Center and UCLA.

Additionally, our partnerships with three of the leading next generation sequencing companies are already providing access to patients in community based practices. Using NGS platforms, we are now routinely able to identify patients with TSC1 or TSC2 inactivating alterations who are eligible for the PRECISION 1 trial.

We have broad geographic coverage in the United States and are leveraging the NGS provider's internal physician networks to locate and identify new potential patients on an ongoing basis. When patient is identified, who is out of network, we have developed systems for referral to a locally participating center.

And we're also employing white glove services to simplified patient access to treatment whenever needed. Importantly, we expect to finalize our partnership with U.S. Oncology shortly. And this will further enhance our ability to identify patients for our trial. Using U.S.

Oncology STAR program, we can rapidly activate individual sites once the patient is identified who qualifies for the trial. We are relatively early in the process, but our multifaceted approach to rapidly identifying the appropriate patients with TSC1 or TSC2 inactivating alterations who may benefit from trial participation is showing promise.

We continue to believe that these efforts will drive full patient enrollment into the study within 24 months.

The reception from the oncology physician community is encouraging and we are increasing our outreach to several specialty areas including gynecologic and genital urinary oncology in order to enhance enrollment of these patient populations into the PRECISION 1 study.

Additionally, we are continuing to carefully evaluate other potential opportunities for either single agent or combination therapies with Napserolomus to expand use and other patient populations. I will now turn it over to Scott for a financial update.

Scott?.

Thanks Loretta and good morning. We have a solid financial quarter as we closed out the first half of 2022. We remain well capitalized ending the second quarter with cash and cash equivalents of $118.7 million based on our current plans and as we said at the close of the prior quarter. We expect cash and cash equivalents to fund operations into 2024.

Total revenue for the quarter, which represented the first full quarter of FYARRO and our product sales was $3.4 million. Cost of product sales amount to $0.3 million for the quarter, consisting primarily of royalties on FYARRO sales.

Cost of sales continues to be favorably impacted by FYARRO inventory costs incurred prior to FDA approval, which were expensed as research and development in the period incurred. Research and development expenses for the quarter were $7.7 million compared to $3 million in the prior year quarter.

This increase is primarily related to the ongoing PRECISION 1 trial and the build-out of the R&D organization. Selling, general and administrative expenses increased to $10 million in the second quarter from $0.6 million in the same period in 2021.

This notable change is primarily due to the build-out of our commercial operations and infrastructure and increased marketing expenses related to the commercial launch FYARRO.

As previously disclosed, during the quarter we recorded a non-cash $3.7 million impairment charge to write-off the value of our intangible asset related to the Gossamer license agreement with our predecessor Aerpio.

Net loss for the second quarter was $18.3 million compared to $1.5 million in the second quarter of 2021 excluding the $3.7 million impairment charge. Net loss for the quarter was $14.6 million For more information, a detailed discussion of the results reported on this call will be provided in our 10-Q to be filed later today.

I'll now hand the call back to Neil for his closing comments.

Neil?.

Thank you, Scott. As we have shared today, the second quarter was one of continued progress in both our commercial growth and further advancement of the PRECISION 1 trial. We're very encouraged by the early acceptance of FYARRO from treating physicians at the major sarcoma centers and commercial uptake in the community setting is encouraging as well.

Our commercial team continues to build awareness and educate physicians on this first and only treatment for malignant PEComa and on making FYARRO available as the first-line treatment option for this rare disease.

We remain intently focused on enrollment for our PRECISION 1 trial in TSC1 and TSC2 altered solid tumors and we look forward to sharing preliminary data with the community in the first half of 2023.

Looking ahead, I'm confident that we are well positioned to continue to execute successfully and we look forward to creating value for our stakeholders from patients and clinicians to employees and shareholders. We will be participating in conferences and meetings throughout the fall with the goal of further building awareness around our story.

With that, we can open the line for questions.

Operator?.

Thank you. [Operator Instructions] Our first question comes from the line of Boris Peaker of Cowen. Please go ahead..

Good morning. And congratulation on excellent commercial progress.

Can you guys hear me.?.

Yes..

Yes, we can hear you, Boris..

I can hear you..

Great. So and my first question is, can you comment on what is the typical process for a PEComa patients being diagnosed and where can we find potentially patients that have been mis diagnosed.

Okay, this is Neil. So I'll start with that. So the PEComa patients if they're diagnosed correctly. To begin with will end up in general at one of the sort for the large academics sarcoma centers that and diagnosed itself is a pathological diagnosis So with histochemistry and general pathology, there's usually no NGS or molecular testing involved.

So that's how the PEComa patient is typically diagnosed. Now, they would obviously be treated first for sarcomas or the pathologist would identify sarcoma sometimes that ends up being misdiagnosed, as is common in sarcomas, by the way up to maybe 20%, 30% of - patients within general sarcomas are also misdiagnosed as to the subtype.

So there's an education process there that we have initiated some time back on the PEComa opportunity for the pathologist [technical difficulty] diagnose growth. The patient and - put forth the diagnosis for so that these patients can get FYARRO.

If there's misdiagnosis, then the patient might go through some standard treatment that is for sarcoma, and not necessarily mTOR inhibitors. But eventually they will land and get referred to one of the larger trauma centers and get correctly diagnosed. This is part of the education piece as well that our team is working on.

And actually they should be triaged onto FYARRO..

Got it.

And in the context of that are you guys doing any additional epidemiology work FYARRO itself to understand with the new incidences and where the prevalence is, and if so when may you be able to share some of that to the investors?.

Yes, I'll pass that over to Brendan obviously with commercial experience we gain more information, but it's still early. Brendan, would you like to comment on it..

Yes Boris. I think as Neil said I think the commercial experience we need to step through that initial bolus and then really start to track the underlying patient demand and I think growth better that just as time passes.

I think we'll also start to see and we've already started to see a small sample of claims data although that's representative about 30% of the catchment landscape. I think it's still helpful in determining looking at that and triangulating with our data and trying to make a better assessment.

So I don't think we're there yet, it's still early and we're kind of sticking with the original estimate. But I think using new data sources post launch works, help us kind of narrow win on that over time if that helps..

Great, thanks for taking my questions..

Thank you. [Operator Instructions] Our next question comes from Joe Catanzaro with Piper Sandler. Please proceed..

Hi, this is Sam on for Joe, thanks for taking our question.

First, could you just provide a little more detail on maybe what the extent of first-line usage, you're seeing and then also how many new patients starts did you observed in this quarter?.

I'm going to pass that question on to Brendan. Brendan, please go ahead..

Yes. It's really hard to tell right now, exactly, what the line of therapy is, we expect and this is, kind of from intelligence in the field that a lot of these initial patients are heavily pretreated with a second line. Obviously, some of the EAP and ampac patients were rolled over, they're heavily pretreated.

But at the end of the day, it's hard to tell how. However, it's encouraging we have -- do tracking studies with the universe and the intent to prescribe in the front line is well north of 75%, right. So I think it's just only a matter of time and execution and kind of patient flow that we get to a pretty dominant market share in the frontline setting.

It's just hard to tell today. As far as new patients, very difficult, but I would say if you start to look at the account number that we provided, the 60 ordering accounts. I think that's the closest you can get to estimating, although it's not a perfect number, because there could be multiple patients within each account, right.

So it gets a little more blurry, the further you go, but I think it's the best we can do given the lack of data we have with an IV therapy.

Perfect, thanks. And then I guess, do you have any comment on like early duration of treatment and what you're, I guess there in terms of time on right now..

No, again, the duration of treatment will evolve over time, as you can imagine, if you're getting later line patients, you expect a little bit of a shorter duration upfront. And then to your question, if you can fully penetrate the frontline setting, I think that's where we'll start to see a much longer duration. So that will evolve over time.

However, we did provide, again, with limited data, the reorder rate that would - I have provided in my prepared remarks, north of 80%, it's encouraging.

Again, not a perfect measure of it, but when -- if you assume at account orders and puts a patient on therapy, the fact that they continue to reorder in vivo [ph] amounts that would kind of mimic the dosing and schedule of a patient. That's at least encouraging not a perfect metric, but it looks good.

And the fact that more than 80% reorder rate is, I think, pretty encouraging. The other thing I would say on that is, the feedback from clinicians has been very positive, right.

They're able to start patients, but in that way hearing from our representatives, that those patients are continuing on therapy and continuing very well, is very encouraging, right. And I think many physicians see this as a very differentiated drug and one where you see response pretty early right.

And so the clinical experience that builds, leads me to believe that will, over time, start to kind of maximize the duration of therapy, especially as we penetrate the frontline settings..

Thanks So much.

And then for our last question in terms of your future monotherapy plan, do you expect this will be associated with specific biomarkers beyond TSC1 and 2 or maybe specific tumor types?.

Yes, so thanks for the question. This is Neil. Obviously, we're doing a pretty wide evaluation, and comprehensive evaluation of the full potential of FYARRO used across different tumor types.

And as you know the prior mTORs, while everybody's excited about the mTOR target or was excited, the prior approved therapies haven't quite delivered the punch that should have been expected with such a central target. With FYARRO we want to fully maximize that potential.

And therefore we're going after essentially a very broad swath of indications, where mTOR signaling is key.

So that's sort of the first thing to look at in which indications does mTOR signaling prevail as a driver or even become a resistance mechanism, and then that allows us to narrow in on whether we go for monotherapy or even as a combination with other targeted therapies, where resistance mechanisms related to mTOR pathway may evolve.

This is an ongoing process. And we'll continue to do that evaluation for the rest of the year with the with the intent to probably open new studies as early as next year..

Thank so much..

Thank you. Our next question comes from the line of Jiale Song with Jefferies. Please go ahead..

Great ,thank you, and congrats for all the progress and the first full call, full quarter for the FYARRO sales. A couple of questions related to the sales. First among this $3.4 million sales in the second quarter, how much of them are inventory build versus the product sales.

I think in the first quarter your comment, most of them are from the gap and the pent up demand. But you did see some inventory in view. But just curious in the second quarter, how much is for the inventory? Thank you..

Yes. Hi, this is Neil.

So Brendan, would you like to take this one?.

Yes, sure. Hi [Roger] thanks for the question. The inventory has, initially, Roger was high. And that's where I think as distributors were trying to get a feel for the initial bolus and kind of what they needed to carry. I think, since that time, it's come down to what I would say normal levels in the 2 to 3 weeks.

So the inventory has returned to normal levels. I would say, though, that the carryover, which I mentioned in my prepared remarks is still pretty significant right? I mean most -- there's a fair number of patients who were put on early from this bolus, whether through just EAP carryover or pent up demand that continue on therapy from what we can see.

Now that's a positive, but it also kind of can mask a little bit of the data, new patient flow and underlying demand. So the positive is that the patients are continuing, but as far as giving us better visibility on the data is -- it makes it a little difficult if that helps..

Yes that's very helpful, thank you. And then in terms of the gross to net, I understand your target is 80% to 85%. But just curious, do you have a sense to what is the current gross to net? And did that change over time since launch, particularly after you have the -- you activate the J code in July 1..

Brendan, would you like to take that? And maybe Scott can also comment..

Yes. No, I think it's still relatively early, Roger, so we don't have enough kind of data, as you know, kind of reporting and things like that sometimes comes on a delay. So we're still sticking with that 15% to 20% number, and I think we'll be able to narrow that towards the end of the year. Scott, I don't know if you have additional comments..

No. I mean I agree with what you just said, Brendan. I mean the thing you do know, Roger, is that some of the government pieces can take time. And so we are still fairly early, but our expectations around where we'll end up have not changed..

Excellent thank you. Maybe just a last one related to the PRECISION 1 trial. Since you have started those, the first patients since March so any kind of initial feedback from the site? And do you see the level of interest increase and the enrollment pace pick up a little bit since you are opening more sites now? Thank you..

Yes. I'll pass it on to Loretta to comment..

Hi and thank you for that question. We are seeing a high level of investigator interest and it is clear something that Neil said earlier that mTOR is a target that is central and was associated with a great deal of interest at one point in time. Unfortunately, the earlier drugs were associated with toxicity and really didn't deliver.

They're hard drugs to give. They are poorly absorbed and we now have another way of going after mTOR, a way that reduces toxicity and is apparently a great deal more active. So the community is really quite excited about this. They know about the target. This is not a rare not -- certainly not a rare mutation.

We think there are approximately 12,000 patients annually in the United States. We have a drug that is derisked. It's already approved. So our early report is that we are on track. The trial is clearly on track, thanks to the hard work of a very dedicated group of folks who worked hard on this program.

And we're confident at this point in time that we're going to be able to enroll this trial within 24 months. I hope that gives you the color you were looking for..

Yes that's very helpful thank you for taking the question and congrats for other progress again. Thank you..

Our next question comes from Robert Burns with H.C. Wainwright. Please proceed..

Hi guys, congrats on the quarter. Just one follow-up for me, if I may so considering that there was a bolus of patients that started in 1Q, and you said earlier that some of them carried over into the second quarter, which obviously impacted the revenue.

I'm sort of curious if you had any insights to what percentage of the patients from the second quarter will actually hold over bolus patients from the first quarter?.

Yes. Thanks, Robert, for the question.

Brendan, would you please answer that one?.

It's -- you know what, I appreciate the question. It's really hard to pinpoint what that number is. And it's really -- a lot of this is even on the number of patients that transitioned is a little bit of guesswork and kind of on-the-ground intelligence instead of really data driven. And so that's the difficulty in providing a number.

Again, we're loosely trying to see that, okay, if a patient or an ordering account, where we expect that a patient transitioned from the EAP, if they continue to order into Q2, what we're trying to say, okay, that's there's probably a patient continuing, but it's not a perfect science.

So I don't want to necessarily speculate on the percentage because it's not very clear, and it's a lot of guess work at this point, given the lack of data..

Okay that's completely fair..

So Robert, maybe just a clarifying comment there is I think everybody knows this, but because this is an IV therapy, the tracking is a little different from if it were oral. And so we lose sight of the sort of the individual and patient at the time the drug is academic center. So I think that's why there's, some of these uncertainties..

No, that's completely understandable, Neil. Thank you guys again and congrats for the quarter..

Thank you. And with that, we finish our Q&A session for today. I will turn the call back to Mr. Neil Desai for his final comments..

Yes. Hi, everyone, and thank you again for joining us today. We appreciate the questions, and we appreciate the interest. We appreciate your time, and we look forward to the opportunities coming up in the fall to provide additional updates on our progress. Have a good day. Thank you..

And ladies and gentlemen, this concludes today's conference call. Thank you for your participation and you may now disconnect..
