Nancy Simonian

Thank you, Naomi. The first half of 2021 was very productive for CERO. and I am pleased to provide an update on our recent progress. As we outlined at the end of last year, we are focused on three strategic priorities. First, we are advancing a growing portfolio of targeted therapies for hematologic disorders, each with the potential to set a new standard of care. Second, we are building on our leadership in selective CDK inhibition for difficult-to-treat cancers. And third, we are continuing to leverage our gene control discovery engine to fuel a robust and sustainable pipeline. Together, we believe these efforts will enable us to build Cirrus into a fully integrated company with medicines that provide profound benefits for people with cancer and monogenic diseases. In the second quarter, we made great strides across all our clinical stage programs. Starting with SY5609, as we announced this morning, we have entered into an agreement with Roche to evaluate 5609 in combination with atezolizumab, a PD-L1 inhibitor, in patients with colorectal cancer. We are very excited to work with Roche to explore this novel combination. There is strong preclinical and mechanistic rationale for combining 5609 with a PD-L1 inhibitor which David will discuss later in the call. Notably, this marks the first clinical investigation of a selective CDK7 inhibitor with immunotherapy, potentially paving the way for additional combination strategies for 5609 with immunotherapy. We also announced this morning the data from the dose escalation portion of our phase one study of 5609 will be highlighted in an oral presentation at the ESMO Congress in September. We remain on track to move into the expansion portion of the Phase I trial in the second half of the year, and at the time of the data readout, we plan to further detail our next steps for advancing the development of 5609 to further explore its potential as a transformative, targeted approach for difficult-to-treat cancers. Turning now to our targeted hematology portfolio, We continue to make progress and select MDS1, our phase three clinical trial of tamiberitine, formerly known as SY1425, in combination with azacitidine in RARA-positive, higher risk MDS patients. We are also on track to initiate both select AML1, our randomized phase two trial of tamiberitine plus venetoclax and azacitidine, as well as our dose confirmation study of SY-2101 in APL this year. Together, these programs put us on track for two potential NDAs in 2024, for tamiberitine in MDS and for 2101 in APL. Our recent three-part KOL webinar series highlighted the opportunities for tamiberitine in 2101 to set new standards of care in MDS AML, and APL, further defining the value proposition for these programs. These three webinars featured key opinion leaders who are intimately involved in the treatment of people living with MDS, AML, and APL. These were incredibly impactful events for us at Xero. Each physician articulated a tremendous gap in the treatment landscape, highlighting the urgent demand for new therapies that can provide patients with better clinical outcomes, or in the case of APL, a dramatically reduced treatment burden. The KOLs described the potential of Tamiveritin and 2101 to address these needs, and also shared their views on how Tamiveritin and 2101 are distinguished within the current treatment and development landscape. Beginning with our MDS-focused event in May, Dr. Amy DeZern of Johns Hopkins provided an overview of the higher risk MDS landscape, underscoring the need for tolerable therapies that can improve outcomes while offering quality of life. HMAs, including azacitidine, are the current standard of care and offer limited efficacy. Prognosis after HMA failure is very poor. Moreover, most higher risk MDS patients are elderly and either can't or don't want to undergo the intensive chemotherapy necessary to bridge to a potentially curative bone marrow transplant. Dr. DeZern highlighted one of the major challenges in MDS drug development. MDS often presents as a polyclonal disease, making it difficult to treat with therapies that target individual genetic mutations. In her view, a combination of factors distinguishes Tamiberitone in the current landscape. the fact that it targets a biologic process fundamental to the differentiation of blood cells as opposed to targeting a single genetic mutation, the ability to select for patients most likely to respond, the high complete response rates in AML, which have a reasonably likelihood of translating to higher risk MDS, and a favorable tolerability profile that does not exacerbate neutropenia and other complications when combined with azacitidine. Turning now to our AML-focused event. In June, we were joined by Dr. Daniel Pallier of the University of Colorado. Dr. Pallier's presentation focused on the unmet need in AML and the paucity of options available to put people in long-term remission. While Vaneza has emerged as a tremendous option for many patients, a third of newly diagnosed unfit AML patients don't respond, and many more relapse, leaving them with poor options. Dr. Paglia explained that these non-responders tend to be patients with monocytic disease. As we presented at ASH, our translational data suggests that the RARA biomarker enriches for the monocytic disease phenotype associated with venetoclax resistance. Simply put, By selecting Ferrara, we believe we may be enriching for the very patients who are in the greatest need for new treatment options. Dr. Paglia also highlighted the characteristics of an optimal AML therapy. An oral medicine that allows for deep, durable remissions with minimal or manageable toxicities and that has rapid impact on disease progression, where you can tell quickly if the therapy is working. Based on our data to date, we believe tamiberitine may offer this product profile. In our phase two trial, tamiberitine plus AZA delivered high CR rates with a rapid onset of action, meaningful durability, and a good tolerability profile in RARA positive newly diagnosed unfit AML. This gives us confidence in our triplet strategy with tamiberitine plus then AZA. Like MDS, AML can be a polyclonal disease. By employing the triplet combination upfront, we hope to achieve high initial response rates while reducing the emergence of resistance disease by simultaneously targeting both monocytic and non-monocytic leukemia cells that may be present at diagnosis and lead to a short duration of response and relapse. We look forward to beginning to enroll patients in the select AML1 trial later this year. Our final KOL webinar, on APL was just a few weeks ago. APL is a clinically distinct form of AML defined by a RARA gene fusion. We were joined by Dr. Farhad Ravandi Kashani of MD Anderson Cancer Center, who highlighted how an oral therapy would represent a major advance for patients. While IV ATO plus ATRA, the current standard of care, is curative in greater than 80% of patients, it comes with an enormously heavy treatment burden. The regimen involves up to 140 lengthy infusions over nearly a year. 2101, a novel oral form of ATO, has the potential to deliver comparable efficacy while dramatically reducing the treatment burden. We plan to initiate our dose confirmation study this year with the phase three trial to follow in 2022. If you are interested in hearing more, a full audio replay of each of these events, as well as the accompanying slide presentation, is available on our website. With that, I'd like to turn the call over to David.

speaker
Naomi

Thank you, Nancy. Given the proximity to the data readout for our Phase I dose escalation study, I will focus my comments today on SY5609 and review the details of our study. As you've heard us describe before, 5609 is a novel targeted approach that we believe holds great promise for difficult to treat cancers. 5609 disrupts two important processes that cancer cells use to survive and thrive, transcription and uncontrolled cell cycle progression. Inhibiting CDK7 leads to reductions in cancer-driving transcription factors and anti-apoptotic proteins, and disrupts critical nodes in the cell cycle, attacking cancer in multiple ways and at multiple points. As part of the dose escalation, we're exploring 5609 in breast, colorectal, lung, ovarian, and pancreatic cancer patients, as well as in patients with tumors of other histologies, with RB pathway alterations. We chose these specific tumor types because of the strong preclinical data, high unmet need, and mechanistic rationale based on either a high prevalence of RB pathway alterations or known transcriptional and cell cycle dependencies. In keeping with our development philosophy of exploring both single agent and combination strategies early in development, the dose escalation was designed to assess 5609 as a single agent, as well as in combination with fulvestrant in HR-positive breast cancer, a combination that we could explore in parallel with the single-agent cohorts. We began enrollment in the dose escalation in January of 2020, and we shared encouraging early data from the dose escalation at the EORTC NCI AACR meeting last October. Importantly, Those data demonstrated proof of mechanism at tolerable doses and pharmacodynamic activity at levels consistent with anti-tumor activity in our preclinical models. At the time, we had established the MTD for continuous daily dosing and had opened cohorts to begin exploring alternate doses and schedules with the aim of identifying the optimal dose and schedule to take forward into expansion. one that would allow us to deliver 5609 at a dose and schedule that would be tolerated over prolonged periods of time, and that could also position us for various additional combination strategies. At ESMO, we will share a more robust data set from the ongoing dose escalation. This update will include safety, tolerability, and initial clinical activity data from patients treated at a range of doses on multiple different intermittent schedules. In addition, we will present two preclinical abstracts that complement this clinical readout, one evaluating the anti-tumor and pharmacodynamic activity of intermittent dosing regimens with 5609 in ovarian cancer models, and one evaluating 5609 as a single agent and in combination with chemotherapies in models of KRAS mutant cancers. As we announced in our press release this morning, due to changes in the development landscape with the emergence of oral selective estrogen receptor degraders or SIRD therapies, we are no longer exploring the combination with fulvestrant in HR-positive breast cancer patients in our trial. Oral SIRDs are expected to become the standard of care in this patient population, making the development path for a combination with fulvestrant less clear. As a result, we prioritized our efforts on the other cohorts in the dose escalation. 5609 has shown preclinical synergy with an oral CERN in HR-positive breast cancer cells, and we continue to believe it has potential in HR-positive breast cancer. We believe that combination strategies remain key to unlocking the true power of any therapy in cancer. To that end, we are excited to discuss the agreement with Roche, to explore 5609 in combination with its PD-L1 inhibitor. Under the terms of this agreement, we will supply 5609 for a combination dosing cohort in Roche's ongoing intrinsic trial, a Phase I, Phase Ib study evaluating multiple targeted therapies and immunotherapies as single agents or in rational combinations in molecularly defined subsets of colorectal cancer. The cohort evaluating 5609 in combination with atezolizumab is in patients with BRAF mutant colorectal cancer. We believe there is a strong mechanistic rationale and translational data to support this approach. Preclinical data show that CDK7 inhibition induces DNA replication stress and genome instability in cancer cells. triggering immune response signals. In animal models, CDK7 inhibition enhances tumor response to anti-PD1 immunotherapy, prolonging overall survival and increasing immune cell infiltrates. Additionally, our preclinical data shows that 5609 inhibits tumor growth at well-tolerated doses in colorectal cancer models, with deeper responses observed more frequently in models with BRAF mutations relative to wild type. We look forward to working with Roche to evaluate the potential of this novel combination. In parallel, we remain on track to advance 5609 into the expansion portion of the phase one trial later this year, and we look forward to sharing more details on our next steps for 5609 at the time of our data disclosure in September. With that, let me turn the call over to Gerald to review our second quarter financial results.

speaker
Nancy

Thanks, David. We continue to operate from a position of financial strength. We ended the second quarter with $195.3 million in cash, cash equivalents, and marketable securities compared to $174 million as of December 31, 2020. This increase reflects the $75.6 million in gross proceeds from our January 2021 public offering, partially offset by cash used to fund our operations in the first half of 2021. Based on our current plans, we believe we have sufficient capital to fund our planned operating expenses and capital needs into 2023 beyond anticipated data readouts for each of our clinical stage programs. We recognized revenue of $5.2 million in the second quarter compared to $3.2 million in the second quarter of 2020. This consisted of $3.3 million in revenue under our collaboration with Global Blood Therapeutics and $1.9 million under our collaboration with Insight. In the second quarter of 2020, we recognized $2.5 million in revenue from our collaboration with GBT and $0.7 million from our collaboration with Insight. R&D expenses were $25.8 million in the second quarter of 2021 compared to $14.8 million for the same period in 2020. This increase was primarily due to the advancement of our three clinical programs as well as increases in employee-related expenses. G&A expenses were $5.5 million in the second quarter of 2021 compared to $5.1 million for the same period in 2020. This increase was primarily due to employee-related expenses. Finally, we reported net loss for the second quarter of $22.5 million, or 36 cents per share, compared to a net loss of $17.2 million, or 38 cents per share, for the same period in 2020. With that, I'll turn the call over to the operator for questions. Thank you.

speaker
Operator

Thank you. As a reminder, to ask a question, you'll need to press star 1 on your telephone. To withdraw your question, press the pound key. Please stand by while we compile the Q&A roster. Our first question comes from Ted Tentok with Piper Sandler. You may proceed with your question.

speaker
Ted Tentok

Great. Thank you very much, and congrats on the update. I'm excited to hear a little bit more about the Roche collaboration. Can you tell us a little bit more, and is there the potential to ultimately evaluate it 5609 beyond colorectal. Thanks so much.

speaker
spk02

Thanks, Ted, for the question. David, you want to take that?

speaker
Naomi

Sure. Yeah, no, thanks, Ted. Hi, David. Hello? Hi. Yeah, we're very excited about the potential for SY5609, and clearly we've attracted the interest of Roche, you know, ease the potential not only for advancing this in colorectal patients, but also to advance their immunotherapy and broaden the opportunities that they currently have for tezolizumab. So we see that as a great foundation for moving forward. We also look to our own data, where we've been making great progress in our ongoing study. And since the ENA presentation from last fall, we're looking forward to providing updates At this September at ESMO, we'll be focusing, as we've previously stated, on the safety and tolerability, but also clinical activity. Obviously, since that time, which dated back to data through last August, we've made progress. So you can expect a more robust data set, which will give us insights into where we may be going. And we'll provide that information to you at that point.

speaker
Ted Tentok

Awesome. I'm excited to hear more about it, and I'm looking forward to progress on the rest of the program, too. Thanks so much, guys.

speaker
spk02

Thank you, Ted.

speaker
Operator

Thank you. Our next question comes from Phil Nadeau with Cowan. You may proceed with your question.

speaker
Phil Nadeau

Good morning. Thanks for taking my question. As we get ready for ESMO, I think the key question on 5609 that people are grappling with is, what is the therapeutic window? What's the safety profile? and are there signs of efficacy? It sounds like you're going to be providing data across a wide range of tumor types and a wide range of dosing paradigms at the meeting. So how would you suggest that we prepare for that ESMO data, and how will you yourselves evaluate whether there's a therapeutic window for 5609, and how would you suggest we kind of frame that data as we look at it?

speaker
Naomi

Sure. Again, thanks for that question. I think it's really important to look at the totality of the data that we're going to be presenting. And as I just shared with Ted, we've made a lot of progress since our last data update, having obviously treated more patients than the prior presentation. And so we're going to have a broad data set We, at the time of the EMA meeting, had really been excited to share with you that we achieved a mechanism and that we were achieving that at doses that were tolerable. I think that at this time, you know, we're going to be looking at parameters, you know, and you should help, you know, to help you frame the way in which you are looking at our data, you know, can we identify a dose in the regimen that we can take forward, you know, based on the totality of our safety and tolerability? Also, are we seeing signs of biological activity? Are there early signals of clinical activity at those doses and at that regimen? And then more importantly, you know, what about the specific patients who have been treated? How were they doing? prior to coming on to our study, what were the responses like and how long they were lasting versus what they may be experiencing on our trial. And if you can answer yes to those types of questions, we would share with you great enthusiasm about this. And I also think that it's important to appreciate how the plans moving forward related to the type of activity we might see you know, would be interpreted in that broader context. So, you know, I just think that it should be a very interesting presentation, and I hope you're looking forward to it.

speaker
Phil Nadeau

That's very helpful. Then the second question is, as we think about what could happen next, I guess your corporate presentation says expansion cohorts as a single agent and combination therapy. So it sounds like the range of where you could delineate for us next are new tumor types or – tumor types that you're going to move into as a single agent, and then perhaps other combination regimens. Anything else I'm missing? Any other potential avenues for further development of 5609?

speaker
Naomi

Well, no. Look, I think that it's really important to appreciate, and I believe you do appreciate, how in oncology, drugs are often initially tested in the single agent context And even when they work well in that context, they're often used in various combinations. And so we acknowledged this at the outset and set the stage for this program at this early point in time to give us opportunities to move forward in various ways. And that was really the critically important reason for looking at alternate schedules that may afford us different doses so that we can take this and unlock the power of this drug in a fit-for-purpose approach. You know, I do want to share with you an important experience I had in my past professional life when leading the early clinical development of Pabliciclib, a CDK4-6 inhibitor, which, you know, at that early stage in its development, parallel to where we may be at this point with our CDK7 inhibitor, had nominal single agent activity, but based on preclinical evidence and some early signals, it was clear that to truly unlock the power of that drug, a combination with an aromatase inhibitor was required, and we all know the successful outcome of that strategy. So anticipating that we may need many ways in which to maneuver, we've really focused on setting the stage for a robust future approach.

speaker
Phil Nadeau

That's very helpful. Congrats on the progress, and thanks again for taking my questions.

speaker
spk02

think so.

speaker
Operator

Thank you. Our next question goes from Jason Butler with JMP Securities. You may proceed with your question.

speaker
Jason Butler

Hi. Thanks for taking the question. I guess somewhat of a follow-up on the next steps for 5609. What have been the factors that contributed to your prioritization for the different expansion cohorts that we'll learn about? Is it you know, potential for benefit, unmet need, you know, obviously combination strategies have played in. If you can help us think a little bit more through how you prioritize where to invest.

speaker
Nancy Simonian

Hey, Jason, I'll take that question. You know, one of the, you know, really the beauties, I'd say, of the 5609 approach is that we know it can work. We believe it can work in many difficult-to-treat cancers just based on the target and the mechanism. And so when we think a little bit about the priorities for what we would do moving forward, we think about several things. We think about preclinical data, mechanistic rationale, translational data. We think about the clinical data that's emerging from the dose escalation, the safety and tolerability profile. And then very importantly, we think about unmet medical need, What does the development path look like? What's the competitive intensity? Where do we think, you know, there's a very big unmet medical need that we could potentially serve with this? So it's a kind of a combination of all of those factors that go into our decision around, you know, what to proceed with, you know, obviously beyond what we're doing with Roche with immunotherapy in the expansion portion.

speaker
Jason Butler

Great. And then In terms of the PD-L1 combo, can you maybe just put into context for us, you know, your previous, your focus on the, or what you've learned about the drug in RB pathway alterations, in terms of RB pathway alterations, and put that in context of now looking in BRAF mutations?

speaker
spk07

Yeah, thanks for the question, Jason. You know, we've seen CDK7 inhibition have effects, as you know, both in transcription but also in cell cycle. And as you mentioned, you know, RB pathway is a critical player in cell cycle. But what's been published is that when you inhibit CDK7, most likely due to that effect in the cell cycle, you induce a replication stress. And that stress can result in the formation of signals that induce the innate immune signaling. And in published data, it was shown that that helps a PD-1 inhibitor in a mouse model. So that was really the basis of kind of this immune signaling upon CDK7 inhibition. And of course, as you know, that Colorectal cancer is a place where there's genome instability, and there's immune signaling, and immune therapies have been shown to have some benefit there. So combined with really the strong activity of 5609 and BRAF tumors, xenografts that we showed at ASCO last year, basically all those things combined, kind of the cell cycle interruption, innate signaling, and the activity in the BRAF CRC really make us excited about that combination.

speaker
Jason Butler

Great. Thanks for taking the questions.

speaker
spk02

Thank you, Jason.

speaker
Operator

Thank you. And as a reminder, to ask a question, you'll need to press star 1 on your telephone. Our next question comes from Mark Breidenbach with Oppenheimer. You may proceed with your question.

speaker
Mark Breidenbach

Hey, good morning, guys, and thanks for taking my questions. I'm just wondering if the collaboration with Roche will have any immediate impact on your planned expansion cohorts for 5609, especially in colorectal cancer. And I'm not sure if you'll be able to answer this or not, but David, I'm wondering if you can point to any clinical precedents where a CDK inhibitor, maybe a CDK4-6 or other, has shown synergy with a PD-1 or PD-L1 checkpoint inhibitor.

speaker
Naomi

Sure. So, I think the excitement we have for colorectal cancer, we initially shared that with you last year after ASCO when we had a preclinical presentation showing the range of activity that we saw. And you may remember that we had about two-thirds. We did, I think, 30 PDXs, and two-thirds of those had tumor growth inhibition greater than 50%. with about a quarter having complete regressions, 90% or greater. And the majority of BRAFs were BRAF mutant colorectal cancers were responding relative to those without. And so we really were excited about that opportunity, and that contributed to our inclusion of those patients in our current study. So we're very excited about this. It's really a difficult patient population. And the application of a successful checkpoint inhibitor like atezolizumab to our go-forward plan in colorectal is very exciting given the unmet need and the opportunity to address that. With respect to the underlying mechanism, there has been published data that supports inhibition with CDK7 can lead to DNA damage and replication stress that can induce an immune reaction. There can be associated immune cell infiltrates into the tumors that are exposed to CDK7, and we think that's a clear setup for amplifying the attack with an anti-PD-L1 antibody. So I think it all really makes great, great sense. There has been prior work done with CDKs, you know, CDK4-6 in particular. Paldaciclib and others have been combined with immunotherapies, and the The data on those in certain circumstances can support IO combinations. We think that our unique mechanism, which also involves anti-transcriptional effects with a CDK7, may really potentiate that combination strategy. Obviously, we attracted Roche to bring our program forward with them. and I think they have a shared view of this opportunity along with us, and so we're really excited, and we're happy that it's piqued your interest as well.

speaker
Mark Breidenbach

Okay, great. And can you just give us a ballpark number of patients that we should expect in the ESMO update, if you can? Thank you.

speaker
Naomi

Yeah, so at the time we presented at the ENA meeting, which was a year ago, we had enrolled a total of 17 patients. If I recall, 14 were included in the single-agent component, so That data cut was back in August of 2020. Here we are about a year later, and obviously we've made great progress with the trial. There'll be certainly a larger number of patients. We haven't specified the details of the actual presentation just yet in terms of patient numbers and things of that nature, but suffice it to say it will be a more robust data set. We'll have another focus on safety and tolerability, which is very important, and we also will have more information on various intermittent dosing regimens, like the five-day on, two-day off regimen, or the seven-day on, seven-day off regimen, which were in progress at the time of the past EMA presentation. So I think it should be very helpful. And, of course, clinical activity that we may have seen. And all of this will, you know, help us explain our go-forward plan that we're planning to share with you at around the time of the data release.

speaker
Mark Breidenbach

Okay, thanks so much.

speaker
spk02

Thank you.

speaker
Operator

Thank you. Our next question comes from with Rock Capital Partners. You may proceed with your question.

speaker
Zach

Good morning. Thanks for taking my question. Just wanted to get a little bit more clarity on the deal with Roach. I think the first one for me is just how much control or how involved are you going to be with the study that they'll be running?

speaker
Naomi

Yeah, so in terms of the control, so this is the intrinsic trial, and this is their Phase 1B study. Under the agreement, we're going to be providing them with drugs. We're obviously collaborating in the development of the study design itself, and we'll have access to the information as well as retaining all rights to 5609. but they'll be executing the study and supporting the cost of the actual program itself.

speaker
Zach

Thanks, David. And then does Roche have, you know, right of first refusal if you were ever to pursue a combination with an IO agent in this setting?

speaker
Nancy

Hi, Zach, this is Gerald. So, we retain all rights to 5609. So, we have access to the data and control over 5609. So... You know, nothing further than that.

speaker
Zach

Perfect. And then the last one is just kind of on this, and I think it follows up to some of the questions that have already been asked. Just one, are there any restrictions in terms of where else you can kind of go with this program, whether with this molecule?

speaker
Nancy

No, this is limited to this study, and we have, you know, complete freedom to operate to be able to pursue 5609 requirements. on our own or with anybody else.

speaker
Zach

Thank you. And then I suppose one last one on this one. In terms of decision-making about, you know, what is needed to kind of move this program to the next step, are you guys aligned in terms of what you need to head to move forward, or is it still a decision that we'll be making?

speaker
Naomi

Could you please repeat that? You broke up a bit when I was listening.

speaker
Zach

Sure, yeah. I was just wondering in terms of, you know, what you need to hit to kind of move this program forward. Is it a joint decision or is it solely based on Roche in terms of, you know, what they want to see to kind of move this to the next step?

speaker
Naomi

So, you know, obviously the protocol has been collaboratively designed to we have mutual input and interest in seeing the future success. We haven't really shared the specific details on some of those technical parameters or future business decisions around the next steps at this time.

speaker
Zach

Thanks. Well, really exciting. I know I've been quite excited about this program, so I think this partnership certainly gives it a lot more visibility.

speaker
Nancy Simonian

Thank you, Zegba. We, too, are very, very excited about this opportunity.

speaker
Operator

Thank you, and I'm not sure any further questions at this time. I would now like to turn the call back over to Nancy Simonian for any further remarks.

speaker
Nancy Simonian

Thank you, operator, and thank you, everyone, for joining us this morning. As always, we are appreciative of your support and look forward to updating you again soon as we continue to execute against our three strategic priorities and build Cirrus into a fully integrated biopharmaceutical company. with a deep portfolio of targeted medicines that set new standards of care in cancer and monogenic diseases. Thank you.

speaker
Operator

Thank you, ladies and gentlemen. This concludes today's conference call. Thank you for participating. You may now disconnect.
