Q3-2023 Analysis
Revolution Medicines Inc

Revolution Medicines' Promising Pipeline & EQRx Merger

Revolution Medicines reported significant progress in its pipeline with their RAS(ON) inhibitors showing promising differentiation from other KRAS G12C inhibitors. Particularly, RMC-6291 showed a 50% objective response rate in lung cancer patients and 43% in colorectal cancer patients. Encouraged by these results, the company is evaluating RMC-6291 for late-stage development, with a Phase II monotherapy dose optimization underway. Financially, the company ended Q3 2023 with $813.2 million in cash, and anticipates a GAAP net loss of $385-$415 million for the full year, including accelerated RMC-6236 program costs. They reiterated a cash runway into 2025 and announced a merger with EQRx, expected to close post-shareholder vote on November 8, 2023, which should add approximately $1.1 billion in net capital, enhancing the pipeline's late-stage development.

Promising Clinical Data with Operational Progress

In the earnings call, we see a company that has achieved a 50% objective response rate (ORR) in lung cancer patients previously treated with KRAS G12C(OFF) inhibitors, significantly outpacing the 7% ORR reported for similar patients treated with existing G12C(OFF) inhibitors. They are also reporting a 43% ORR with their RMC-6291 in colorectal cancer, comparable to other KRAS G12C inhibitors combined with anti-EGFR antibodies. These results could be indicative of a significant breakthrough in cancer treatment, particularly considering the suggestion that inhibition of the RAS(ON) state in tumors may offer benefits over existing RAS(OFF) inhibitors.

Strategic Acquisition to Boost Financial Strength

The anticipated all-stock transaction acquisition of EQRx is set to provide approximately $1.1 billion in net capital, strengthening the balance sheet and supporting large investments into late-stage development for their RAS(ON) inhibitor pipeline. A shareholder meeting to vote on the transaction is scheduled, underscoring the management's confidence in the strategic importance of the deal.

Financial Prudence Amid Growth

With regard to finances, operating expenses for Q3 2023 amounted to $123.2 million, reflecting a company in a growth phase with increased costs tied to pivotal clinical trials and manufacturing for key drug candidates RMC-6236 and RMC-6291. The company reports a GAAP net loss of $108.4 million for Q3 2023 and has updated the full-year 2023 GAAP net loss guidance to be between $385 million to $415 million, including noncash stock-based compensation expenses of $45 million to $50 million. Despite this, they emphasize their disciplined approach to spending even in the face of a substantial cash reserve, hinting at a commitment to value creation and operational efficiency.

Clinical Development and Regulatory Strategy

The ongoing clinical trials are focused on understanding drug dosages and combinations, specifically with an immediate priority to enroll patients with non-small cell lung cancer and pancreatic cancer for FDA's exposure response analysis. While the company is refining the study design for a pivotal trial, including discussions with regulators, they are clear about continuing with dose escalation for pancreatic cancer to determine the most effective dose, with a possibility of testing up to 500 milligrams.

Outlook on Regulatory Pathways

The discussion also touched upon strategic pathways to regulatory approval, with the team referencing the customary accelerated approval response rates of 25% to 30%. There appears to be a calculation on their part to adjust strategies and expectations based on observed response rates within key demographic and disease cohorts, with a tissue-agnostic perspective also being considered.

Mark Goldsmith

Thank you for joining us. I'd like to focus first on our remarkable headline investigational drug, RMC-6236 and try to paint the picture we see based on a couple of important weeks of data updates an extensive dialogue with investigators and clinical experts. First, objectively and by hands-on investigator experience treating over 131 patients so far, RMC-6236 is well tolerated at clinically active doses, including 300 milligrams QD as reported to us by investigators. These observations with the first-ever RASMULTI inhibitor in the clinic, our dogma breaking and demonstrate clearly that this compound has a very sound therapeutic window. Second, this profile is enabling continuity of dosing, which we believe is critical in treating RAS-addicted cancers. Patients receiving RMC-6236 have required few dose interruptions and even fewer discontinuations for intolerability. This differentiating feature of RMC-6236 is a core lever for evaluating meaningful clinical benefit. Third, despite the inter-patient variability that is typical for oral anticancer agents, RMC-6236 showed dose-dependent increase in exposure at every dose escalation tested up to and including 400 milligrams daily. Fourth, RMC-6236 has shown objective anti-tumor activity, both by radiographic imaging and ctDNA quantitation against 3 oncogenic RAS gene types for which no other targeted therapy is available, KRAS G12D, G12V and G12R. G12D and V alone account for more than half of all RAS solid tumors. And G12D, V and R mutations are the 3 most common RAS drivers of pancreatic ductal adenocarcinoma, accounting for nearly 90%. The results with each of these genotypes individually represents a first-in-class clinical validation for a direct RAS inhibitor and the breadth of activity is simply unique, a true RASMULTI inhibitor. It is not possible to discern any obvious relationship between dose and objective response rate by RECIST at this stage in the study, probably due to small numbers at each dose level and the bias towards short follow-up at the high dose levels. With increased numbers of patients now enrolled and ongoing maturation of the data, we expect to be able to conduct a robust exposure efficacy analysis using several outcome measures. The blended objective response rate in non-small cell lung cancer is already solid at 38% in the data we shared in October. Some patients are expected to develop a partial response after the first scan, we anticipate this number settling out in the 40% to 50% range at recommended Phase II dose and objective response rate in lung cancer generally correlates with progression-free survival. So we plan to select a candidate dose to discuss with the regulators and execute the foundational work to enable a pivotal Phase III trial in second-line RAS-mutant non-small cell lung cancer to begin in 2024, and while we continue collecting durability data. The blended objective response rate in pancreatic ductal adenocarcinoma and the data we shared in October was a respectable 20% and which may change as we gather more data at higher doses, follow patients on treatment longer and hone in on a go-forward dose. One relevant benchmark for comparison we've highlighted is the objective response rate for cytotoxic chemotherapy that has been reported across many studies in second-line pancreatic cancer, which hovers in the 7% to 11% range. Notably, most patients treated in the RMC-6236 study so far have had 2 or more lines of treatment previously, making them third-line or later by definition. In the context of third-line or later, the reported objective response rate has been 0% to 4%, while the response rate for such patients in our study was at higher-higher than the overall 20% number. For all of these reasons, our expert advisers, and we believe that RMC-6236 is performing well by this standard for patients who are facing grim prospects with standard of care. While these objective response rate observations are encouraging, we continue to emphasize that objective response rate is not the key clinical endpoint for pancreatic ductal adenocarcinoma since rapid progression with short overall survival is the norm, even in those who respond initially to established treatments. We expect that doctors, patients, regulators and payers will be driven by durability of clinical benefit as indicated by progression-free survival and overall survival. Median progression-free survival for standard second-line pancreatic ductal adenocarcinoma treatment consistently has been reported to be approximately 3 months and may be shorter for patients beyond second-line. It's too early for us to project these parameters for RMC-6236, and it will take some time into 2024, for us to be able to establish a true median PFS. But here, there are also encouraging signs. The disease control rate we shared in October was 87% and significantly higher than most reports for salvage chemotherapy in pancreatic cancer. Many patients on study have already crossed the median PFS threshold mentioned above and remain on treatment, including as far out as 48 weeks. This statement is true even for patients who have not yet shown an objective response. 20% of patients without a partial response were still on drug at 18 weeks, with many of these 20% having reached 21 or more weeks while continuing on drug, well past the short duration benchmark for second-line pancreatic ductal adenocarcinoma. Even the few patients with a partial response who progressed did so at 18 weeks or later. These are highly encouraging findings. Finally, we believe we have a proposed recommended Phase II dose for lung cancer in hand now, and expansions are underway to develop a robust data set we think is needed to satisfy project Optimus. We have strong conviction about the potential clinical impact of RMC-6236 and serving the real unmet needs in lung cancer and with continuing consultation with advisers and engaging as appropriate with regulators, in 2024, we expect to initiate a pivotal Phase III monotherapy second-line non-small cell lung cancer trial focused on achieving full regulatory approval and with a potential accelerated approval opportunity built in via an interim analysis. Investigators globally are highly interested in participating in this study. We are likewise excited about the potential for RMC-6236 in pancreatic cancer, where unmet needs are certainly profound. Here, PFS is the gating parameter for advancing into late-stage development since ORR is an unreliable predictor of durability. We expect to establish RMC-6236 durability profile via median PFS and identify a recommended Phase II dose in 2024. With that in hand and continuing consultation with advisers and engaging as appropriate with regulators, we are designing a pivotal monotherapy trial in pancreatic cancer, potentially to be initiated in 2024. Our base plan currently is a Phase III randomized trial for second-line treatment, but we are also evaluating options that could accelerate our reach into first-line. Investigators globally are highly interested in participating in this study or studies as well. Next, I'd like to comment on our exciting second investigational drug to show clinical activity, RMC-6291 for KRAS G12C cancers and try to paint the picture we see based on the recent update and extensive dialogue with investigators and clinical experts. First, objectively and by investigators who have treated more than 63 patients so far, RMC-6291, is well tolerated across a wide range of clinically active doses, and so far, investigators report that it is well tolerated. Asymptomatic prolongation of QTC on electrocardiogram has been seen in some patients, only infrequently exceeding the 500 millisecond threshold. Investigators broadly do not consider this laboratory finding, a key limiter to clinical development of this compound. Second, good tolerability enables continuity of treatment and patients receiving RMC-6291 have required a few dose interruptions and even fewer discontinuations for intolerability. Third, 6291 has shown objective of antitumor activity, both by radiographic imaging and ctDNA quantitation in both non-small cell lung cancer and colorectal cancer. Notably, in lung cancer, the ORR and the data we shared in October was 50% in patients who had recently progressed on prior treatment with an approved KRAS G12C(OFF) inhibitor. The only comparable reported data in similar patients using a G12C(OFF) inhibitor showed an objective response rate of 7%. Similarly, the ORR for single-agent RMC-6291 was 43% in colorectal cancer patients who had not yet experienced a RAS inhibitor, similar to reported data from G12C(OFF) inhibitors when used in combination with anti-EGFR antibodies. These results indicate 2 dimensions of clinically meaningful differentiation from other KRAS G12C inhibitors. This differentiation is highly encouraging for the potential of RMC-6291 itself as a drug, and it supports our preclinical prediction that inhibition of the RAS(ON) state in a human tumor may be biologically differentiated relative to inhibition of the RAS(OFF) state. Further, we believe this paradigm likely applies across our portfolio of RAS(ON) inhibitors boosting the probabilities of success across our entire deep pipeline. Fourth, based on these findings, we believe that RMC-6291 is an investigational drug with a profile that deserves to be evaluated in a late-stage development program. There remains several options to be considered and strategic decisions will need to be made among them based on further data we are collecting. These include monotherapy approaches built directly upon the differentiated response profile described above, and we are currently conducting monotherapy dose optimization with the goal of selecting the single-agent recommended Phase II dose with a project optimist data package that supports it. We are also committed to evaluating several compelling combination options very soon, and indeed have already begun recruiting for the exciting pairing of RMC-6236 plus RMC-6291 based on compelling preclinical observations. In aggregate, these findings are highly encouraging and point to large opportunities ahead for these first 2 compounds. Based on this momentum, we look forward to completing the acquisition of EQRx. Let me summarize the status briefly. We expect to acquire EQRx in an all-stock transaction to gain an estimated $1.1 billion in additional net capital after estimated post-closing EQRx wind down and transition costs. a significant quantum of capital that can be deployed for Rev Med programs and more than we had estimated conservatively when we signed the deal. Our strengthened balance sheet is intended to enable the larger investments needed to support the parallel data-driven, late-stage development for our RAS(ON) inhibitor pipeline focused initially on RMC-6236, 6291 and 980. Our shareholder meeting to vote on the transaction is scheduled for November 8, 2023, at 11:00 a.m. Eastern time, and the deal is expected to close shortly following the shareholder vote subject to satisfaction of customary closing conditions. The stock exchange ratio determined and announced last week was as follows: each common share of EQRx outstanding will be exchanged for 0.1112 common shares of Rev Med. We estimate we will be issuing approximately 55 million new shares to EQRx shareholders as part of this merger, thus acquiring approximately $20 in estimated net capital per share of the common stock issued in connection with the merger based on our updated net cash projection. Revolution Medicines will continue to focus on our mission to revolutionize treatment for patients with RAS-addicted cancers through the discovery, development and delivery of innovative targeted medicines. Now let's hear from Jack Anders, our CFO, regarding our Q3 financials. Jack?

J
Jack Anders
executive

Thank you, Mark. Turning to our third quarter financials. We ended the quarter with $813.2 million in cash, cash equivalents and investments. Please note, this balance does not include any net proceeds from the anticipated acquisition of EQRx, which is expected to add approximately $1.1 billion in net cash proceeds should the transaction close. Total operating expenses for the third quarter of 2023 were $123.2 million. The increase in operating expenses over the prior year period was largely due to clinical trial and manufacturing expenses for RMC-6236 and RMC-6291, an increase in research expenses associated with our preclinical portfolio and an increase in personnel-related expenses resulting from additional headcount. GAAP net loss for the third quarter of 2023 was $108.4 million or $0.99 per share. We are updating our financial guidance and expect full year 2023 GAAP net loss to be between $385 million and $415 million, which includes estimated noncash stock-based compensation expense of $45 million to $50 million. The increase in GAAP net loss guidance is largely due to the anticipated acceleration of a portion of RMC-6236 manufacturing spend originally planned for 2024. This spend was accelerated as a result of the progress in our RMC-6236 program. We reiterate cash runway guidance into 2025 based on our current plan. Please note that our current financial guidance excludes the impact of the proposed EQRx transaction. And with that, I'll now turn the call back over to Mark.

M
Mark Goldsmith

Thank you, Jack. We believe Revolution Medicines has an unprecedented opportunity to deliver high-impact benefit to patients through our pipeline. And toward that goal, the deal with EQRx will markedly enhance our ability to bring the most out of these exciting compounds. We have heard broad and strong support for the Rev Med portfolio approach and proposed transaction. The Board and management of Rev Med encourage all of our shareholders to vote in favor of the EQRx transaction. The employees of Revolution Medicines renew our deep commitment to out smart cancer on behalf of patients and to build share value for our investors.

[Operator Instructions]. Our first question will come from Marc Frahm of TD Cowen.

M
Marc Frahm
analyst

I recognize it's not been a lot of time since the data cuts that were presented back at ESMO and EMA, but there were a few patients who were unconfirmed but ongoing in partial responses at that time. I'm not sure if you're able to update if some of those have been able to have subsequent scans and that can actually confirm. And then maybe a bigger philosophical question. Over those meetings, we also saw -- and in the last few months, we've seen a handful of trials take on docetaxel in the second-line setting, lung cancer, a handful of different settings within lung cancer. And often, drugs that look pretty promising, have struggled a bit to or even failed to beat just the tax. Just philosophically, since the safety profile looks really good. Why be aggressive and take just tax-on straight-on instead of trying to combine with this taxi since that would seem to be a much easier hurdle on an efficacy side.

M
Mark Goldsmith
executive

Thanks a lot, Mark. I appreciate your questions. Let me comment first on the question of confirmations. A number of those patients really had just squeaked in, in the advanced period we required in order to report them, which means that they just had one scan. And it's only been a couple of weeks since then. So I think for most patients, we just don't have any more information, so I can't really provide an update today. The question of docetaxel as a comparator versus for a monotherapy trial versus waiting for a combination? Well, I think in part the question answers itself a little bit, but maybe Steve Kelsey can give you a little bit more philosophy on that.

S
Stephen Kelsey
executive

I think, Mark, the principle, which we're trying to carry through the whole portfolio, irrespective of lines of therapy is we would like to get chemotherapy out of the equation if we possibly can. And so a good starting point would be a single agent study against dose attacks all to try and beat it, really. I think leaving chemotherapy like docetaxel in the sort of therapeutic alimentarium for patients is suboptimal. And I think that we would just rather try and beat it at hands down and relegate the dose attacks into later line of therapy, frankly. I appreciate that it is certainly an option to do a dose tax in both arms, but that's not really the philosophical basis of our portfolio.

Operator

Our next question will be coming from Eric Joseph of JPMorgan.

E
Eric Joseph
analyst

I just wanted to try and get a little more incremental color on the tolerability profile that you're observing at the 400-milligram cohort and whether you see room to further dose escalate now that 500 milligrams is something that you were contemplating -- and -- just as we think about your backfilling of some of the previous dose cohorts. Can you just kind of elaborate a little bit on your sort of strategy there? What cohorts you're prioritizing perhaps whether you're opening the criteria up for patients with G12C mutation, and perhaps also just sort of how colorectal cancer patients might sort of fall within that scope. Is that a histology you're keen on sort of revisiting here within the Phase I study?

M
Mark Goldsmith
executive

Thanks a lot, Eric. I'll take the first question, and Steve can comment on a second. The first about tolerability. We don't really have any incremental information compared to what we just reported 2 weeks ago. And as you know, once we have the information was submitted to the dose selection committee, and they'll determine where we are with it, whether or not it's a good dose, whether or not we should advance the dose, those determinations will be made in the right time frame with the right data. The second question, I think the question really was how are we -- what are the -- what's the range of options that we're looking at for combinations in the -- over the next 12 months? And how would we prioritize those? .

E
Eric Joseph
analyst

It was sort of -- it's actually more about as you are backfilling some of the prior dose cohorts to sort of take into consideration when thinking about or deflecting the Phase II recommended dose. I guess, really, it's a matter of what dose cohorts, what dose levels are you perhaps growing more aggressively prioritizing and whether sort of the patient mix going in is either perhaps being more concentrated to certain histologies or perhaps even being opened up as well.

M
Mark Goldsmith
executive

So it's about monotherapy and dose selection comment.

S
Stephen Kelsey
executive

For pragmatic reasons, Eric, which are related to, firstly, the number of patients queuing up to get on the study. And secondly, the relative positive guidance coming from the FDA about the specific requirements for -- to fulfill the Project Optimus initiative. We are aggressively backfilling most of the dose levels actually at 300 and below. And the priority right now is to backfill with patients who have non-small cell lung cancer and pancreatic cancer because those are the ones that the FDA are going to be interested in, in the exposure response analysis that we submit them for when we recommend a go-forward dose into Phase III. There is an amendment to this protocol, which has now been approved, it's on clinicaltrials.gov, which allows us to expand in several different histologies, including colorectal cancer and other tumor types. And it also includes -- does include G12C mutant tumors. But that's completely separate from the exercise to select the recommended Phase II dose for both non-small cell lung cancer and pancreatic cancer, the parallel activities at the moment.

Operator

Our next question will be coming from Jonathan Chang of Leerink Partners.

J
Jonathan Chang
analyst

First question, how should investors be thinking about time lines for next data updates across your pipeline?

J
Jack Anders
executive

I don't have much specificity on that right now. Obviously, we've been asked that a lot over the last couple of weeks. We just need to see how things play out. I think it's pretty clear what we're trying to do in the near term. It's largely around dose selection and acquiring more durability data and, to some degree, more ORR data at higher doses. So I don't think we're talking years out, but I can't give you specificity the most sort of narrow question we get asked is, will we make a presentation at ASCO, and I just don't know. In order for us to do that, we'd have to submit an abstract in February, which means we have to know what it is we're going to present in May to do so. So we'll just have to see. But we'll try to provide more clarity once we sort of get past these next couple of months and give some more specificity about expected milestones in the coming year.

J
Jonathan Chang
analyst

And second question, what do you see as the duration of disease control and PFS benchmarks in previously treated PDAC and what do you see a sufficiently good duration of disease control and PFS data relative to those benchmarks?

J
Jack Anders
executive

Yes, I think Steve can comment mostly on the first part of that question because that's objective information. And then as to what we consider an improvement is, will be the subject of ongoing conversation with experts in the FDA.

S
Stephen Kelsey
executive

The benchmark right now is pretty universally set at around 3 months. There are a few series where the PFS is 2 months and 1 or 2 where it's longer than that. But the vast majority of studies that have been done in that second-line salvage setting show 3-month PFS. And frankly, that's when the scans are done, and there's a very dramatic drop-off in freedom from progression at the point at which that second scan is done. So I think that's the key -- that's definitely the benchmark to be. Your question about how good is good. I mean there are 3 constituencies that we have to satisfy here. That's the regulators, those the prescribers, and then there's the payers, and those exist in multiple geographic jurisdictions. So I think the consultations that are ongoing with those constituencies will ultimately decide what is good enough, and then we'll be able to benchmark our actual data against that and decide if that's a meaningful important improvement and decide what to go forward and how.

Operator

And our next question will come from Chris Shabutani of Goldman Sachs.

C
Charles Ferranti
analyst

This is Charlie on for Chris. Just to start, wondering if you could provide some clarity on the 6236-6291 combination trial that's enrolling. Who are you actively recruiting in terms of G12C experience versus naive patients in that study? And then my second question is just regarding the potential for tissue agnostic approval. What does the team see as the clinical bar to reach there in terms of ORR?

M
Mark Goldsmith
executive

Just a clarification on your second question, Charlie. Were you asking about for the combination or for either of those compounds individually or just more generically?

C
Charles Ferranti
analyst

I guess more generically.

S
Stephen Kelsey
executive

The 6236-6291 combination protocol right now is enrolling both lung cancer and colorectal cancer patients. And the colorectal cancer cohort will prioritize patients who have not had a G12C inhibitor. The lung cancer cohort right now allows either. And we're not at the point where we're biasing in any one direction or the other right now because we're still in the dose escalation, dose finding, dose exploration mode, and it doesn't really matter frankly, what disease or prior treatment the patient has for that purpose. So as soon as we've got a dose for that combo, then I think we'll be a little bit more selective about the patients that we want to encourage into the study, and that will, to some extent, depend on what we've seen during the first escalation period. I think everybody knows accelerated approval, getting a little bit harder. The glass is coming off at a little bit. The bar moves around depending on the indication, frankly. But accelerated approvals traditionally have been given for single agents with response rates in the sort of 25% to 30% range. And I don't expect it to be any different for a RAS inhibitor and RAS mutant disease, particularly as the precedent that has essentially been set by the accelerated approvals of sotorasib and adagrasib.

M
Mark Goldsmith
executive

He was asking specifically about the tissue-agnostic, tumor-agnostic strategy.

S
Stephen Kelsey
executive

I think -- no -- but I think the -- in the core indication -- if you pursue a tissue-agnostic strategy, there's going to be a couple of indications that are going to dominate that cohort. And I think the response rate has to be in that sort of 30% range, I think, in order for anyone to take that seriously. Clearly, the point of the tissue-agnostic strategy is there are going to be some indications which are so uncommon. There's only going to be a handful of patients and you won't be able to compute a response rate with any degree of certainty. So we're really talking about the confidence intels around the overall response rate to lead indications within that cohort.

Operator

And we do have time for 2 more questions. One moment for our next question. It will be coming from Ami Fadia of Needham.

A
Ami Fadia
analyst

With regards to the pivotal trial, you're planning in lung, do you believe that you need to generate data in G12C patients before you begin the trial and perhaps give us a sense of the number of patients you think you need to enroll for this type of invested trial design?

M
Mark Goldsmith
executive

Thanks, Ami. I think Steve can comment on that.

S
Stephen Kelsey
executive

I didn't quite understand the first part of your question is?

M
Mark Goldsmith
executive

Do we need to validate G12C in humans before...

S
Stephen Kelsey
executive

Before we including in a pivotal trial. The validation is obviously -- validation is a sort of a fairly hard baked word. I think we want some experience in those patients before including them as a significant part of a pivotal trial. But everything that we have learned from the preclinical models would lead us to expect the activity in G12C mutant lung cancer to be very similar to the activity in G12V and G12V-mutant lung cancer for RMC-6236. And so I don't think we'll validate, but we're going to try and get some information that will help reassure us that what we've seen in the pre-COVID levels is also true in the clinic. With regards to numbers, again, we're still refining the study design. We have -- we obviously have to design that study we have to discuss it with the regulators. And we're still debating whether the G12C mutation should be in the [indiscernible], frankly. So as soon as we have finalized ourselves, I think we'll be in a better position to explain what it is and what we've -- and why we've done that. Right now, there are just a little too many moving parts to be able to be as clear as we might like to be with you, right now.

M
Mark Goldsmith
executive

And if I could add to that on that last point, what Steve's alluding to is sort of regardless of our confidence in the activity against G12C, there still are operational issues associated with having approved G2C inhibitors available and dozens of G12C inhibitors, G12C(OFF) inhibitors in clinical studies. And so there are risks associated with that cohort regardless of the performance of 6291 and so managing that is part of what we're thinking through. And that will probably have more impact on whether G12C ends up in the core nest or on the periphery because we want to make sure to protect the entirely unserved the population that's entirely unserved by targeted therapy today, which is the G12X without C. But we're interested in both, and we'll have to sort that out.

A
Ami Fadia
analyst

If I may just ask a quick follow-up. And maybe if you could sort of just explain the concept of the nested trial design. The way I understood it was, you would power each subset to be able to sort of -- if you could just clarify. .

M
Mark Goldsmith
executive

No, the way it works is the core Nest gets evaluated statistically first. So you enroll patients however they enroll. It has nothing to do with the sequence of enrollment, but then statistically, you test the core group that you predesignated as the core group. If that scores positively then that permits you to go on to evaluating a larger group that still includes the core but also now includes additional patients. And then you can keep -- I mean you could do that 100 times if you want it, you can keep recycling the statistical power. But if at any point, you have to make sure you do it in the right order because if at any point, you don't see positivity then you no longer can go on and test even larger groups because it would be futile to do so.

Operator

And our last question will come from Alec Stranahan of Bank of America.

A
Alec Stranahan
analyst

Just a couple. At a high level, could you maybe talk about anticipated expense ramp to support the multiple mid- and late-stage studies you have planned for 6236 and the new candidates from the KRAS innovation engine. I guess asked another way, how do you continue to be judicious in your spending despite having almost $2 billion in cash on the balance sheet, assuming the EQRx deal closes as -- and just quickly to clarify for non-small cell, is it safe to assume that 500 mg will not be pursued since you said that the pivotal monotherapy dose has been selected. And if so, is the reason just in terms of speed to start the registrational studies? Or was there something you think makes the 500 dose a nonstarter?

Thanks, Alex, for your questions. On the second question, let me just take care of that one and then come back to the expenses. The comment that we believe we have a recommended Phase II dose candidate dose in hand was specifically with regard to lung cancer, where we already have a response rate that's in the zone of where it needs to be and where that is generally better correlated with durability so we can make some good assumptions now, continue planning and kind of pre-execution and then allow the data to catch up with it in 2024. The question about 500 milligrams and higher, really or 400 milligrams and higher, really has to do with pancreatic ductal adenocarcinoma, but we haven't really declared that we have a recommended Phase II dose in hand. In fact, we've made it pretty clear, we want to see what happens not only at 300, but at 400 milligrams. And then as we commented earlier, if we clear that dose level and dose selection committee wants to advance to 500 milligrams, well, then that's what we'll do. So just to separate the 2 statements, they really -- they don't go together there on different concepts.

Expense ramp. Jack, do you want to comment on it?

We haven't necessarily given out any specifics on forward-looking expense guidance outside of our 2023 net loss guidance. But it is fair to say that our expenses will increase from current levels. We are going to be making investments in these programs. We do need some more data in order to fully understand what those investments are. And I think your question is whether we're going to be judicious and with our spend. I mean, we obviously -- we need to make investments, but we're going to be we're going to be wise about this forward basis, but we haven't given any specifics.

If I could just build on Jack's last comment there. The whole point of the transaction just to give us the capital to make the investments in '24 and '25 and beyond that we really need to make in order to maximize value creation by evaluating these first 2, 3 compounds in the right settings and to evaluate them aggressively in a competitive environment, taking into account also all the downstream commercial considerations and regulatory context, exclusivity and pricing and so on. So we will be increasing our spending. There's no doubt, but I think it will increase our productivity and maximize value creation. Our focus is not immediately on porting the capital, but at the same time, obviously, we'll make data-driven decisions, and we have lots of internal checks and balances to make sure that if we do so and that we do so in close alignment with a compelling strategy.
