Good afternoon, ladies and gentlemen, and welcome to Celcuity fourth-quarter And year-end financial results conference call. (Operator Instructions) I would now like to turn the conference over to Maria Yonkoski with ICR Westwicke. Please go ahead.

Maria Yonkoski

Thank you, operator, and good afternoon to everyone on the call. Thank you for joining us to review Celcuity's fourth-quarter and full-year 2023 financial results and business update. Earlier today, Celcuity released financial results for the fourth quarter and full year ending December 31, 2023.
The press release can be found on the Investors section of the website. Joining me on the call today are Brian Sullivan, Celcuity's Chief Executive Officer and Co-Founder; Vicky Hahne, Chief Financial Officer; as well as Igor Gorbatchevsky, Chief Medical Officer, who will be available during Q&A.
Before we begin, I would like to remind listeners that our comments today will include some forward-looking statements. These statements involve a number of risks and uncertainties, which are outlined in today's press release and in our reports and filings with the SEC.
Actual events or results may differ materially from those projected in the forward-looking statements. Such forward-looking statements and their implications involve known and unknown risks, uncertainties and other factors that may cause actual results or performance to differ materially from those projected.
On this call, we will also refer to non-GAAP financial measures. These non-GAAP measures are used by management to make strategic decisions, forecast future results and evaluate the company's current performance. Management believes the presentation of these non-GAAP financial measures is useful for investors' understanding and assessment of the company's ongoing core operations and prospects for the future. You can find the table reconciling the non-GAAP financial measures to GAAP measures in today's press release.
And with that, I would now like to turn the call over to Brian Sullivan, CEO of Celcuity. Please go ahead.

Brian Sullivan

Thank you, Maria, and good afternoon, everyone. In 2023, we made significant progress advancing development of gedatolisib while strengthening our balance sheet and adding to our leadership team. Our Phase 3 VIKTORIA-1 trial remains on track to report top line data from the PIK3CA wild-type patient subgroup in the second half of this year and top line data for the PIK3CA mutated patient subgroup in the first half of 2025.
We were also excited to begin development of gedatolisib for patients with metastatic castration-resistant prostate cancer this past year. Enrollment has begun in our Phase Ib/II trial evaluating gedatolisib in combination with darolutamide, and we look forward to sharing preliminary data from this trial in the first half of 2025. Our VIKTORIA-1 Phase 3 clinical trial is designed to evaluate gedatolisib in combination with fulvestrant with and without palbociclib in patients with advanced hormone receptor positive, HER2-negative breast cancer whose disease has progressed after treatment with a CDK4/6 inhibitor.
We're seeking to improve outcomes for this patient population, which today receives only limited benefit from current second-line standard of care therapies. We estimate that this initial potential target population represents over 100,000 breast cancer patients globally on an annual basis. Current standard of care for these patients includes endocrine therapies such as fulvestrant and regimens that combines fulvestrant with an mTOR specific or PI3K alpha-specific targeted therapy. These therapies only offer modest progression-free survival periods. And in the case of the approved PI3K alpha inhibitor, a very challenging safety profile.
The significant unmet need for these breast cancer patients has led to development and subsequent investigation of a significant number of new therapies, an oral SERD for patients with an ESR1 mutation, an AKT inhibitor for patients with a PIK3CA or AKT mutation was recently approved. Median progression-free survival, or PFS, for these 2 new therapies range from 3.8 to 5.5 months, respectively, in the same patient population in our Phase 3 trial is enrolling.
While the availability of new drug alternatives for patients is always good news, based on the results reported for these drugs, the unmet need for these patients will still remain. To further elucidate the different therapeutic effects of gedatolisib versus other PI3K, AKT, mTOR or PAM inhibitors, we performed a series of nonclinical studies using breast cancer cell lines. We presented the results of these studies during a poster session at the 2023 San Antonio Breast Cancer Symposium. In a panel of 28 breast cancer cell lines, gedatolisib was sound to be more cytotoxic and at least 300-fold more potent on average compared to the single node PAM inhibitors.
Mechanistically, gedatolisib decreased cell survival, DNA replication, protein synthesis, glucose consumption, lactate production and oxygen consumption, more effectively than the other PAM inhibitors. In vivo studies confirmed that PAM PI3K/mTOR inhibition by gedatolisib reduced tumor cell growth more effectively than single node inhibitors in breast cancer patient-derived xenograft models with and without PAM pathway mutations. We believe gedatolisib highly differentiated mechanism of action as an equipotent PAM PI3K/mTOR inhibitor is uniquely suited to most effectively address this unmet need, especially since gedatolisib has demonstrated activity independent of the PIK3CA or ESR1 mutational status of a patient's tumor.
The results from our Phase Ib study in patients receiving the Phase 3 dosing schedule for gedatolisib in combination with polociclib and fulvestrant was very promising. Median PFS was 12.9 months, and the objective response rate was 63%, both of which compares very favorably to published data for current standard of care regimens.
Another important goal for us in 2023 was to begin development of gedatolisib in a new tumor type. In the fourth quarter, we initiated a Phase Ib/II clinical trial to evaluate gedatolisib in combination with darolutamide, which is a potent androgen receptor signaling inhibitor, in patients with metastatic castration-resistant prostate cancer. We enrolled our first patient in the study in February, and we expect to report preliminary data in the first half of 2025.
Treatment options for these patients are limited and there's an urgent need for new drugs to treat them. Numerous preclinical studies have demonstrated interaction between the androgen receptor and PAM pathways, suggesting that combining a PAM inhibitor with an androgen receptor inhibitor may induce a synergistic antitumor effect in patients with prostate cancer.
There's also compelling clinical evidence with an earlier generation PAM inhibitor providing a proof of concept of our hypothesis that combining gedatolisib with an androgen receptor inhibitor may be efficacious. And finally, as we get closer to having data for the PIK3CA wild-type patients in our Phase 3 breast cancer study, we need to begin laying the commercial and marketing groundwork necessary to bring gedatolisib to the clinic.
To head up our commercialization efforts, Eldon Mayer joined our management team as our Chief Commercial Officer in February. Eldon has over 30 years of biopharma commercial experience in companies ranging from early-stage biotechs to full-scale pharmaceutical companies across many therapeutic areas, including oncology. Eldon is an exceptional leader with a proven track record of building commercial organizations from the ground up to support the launch of a biotech company's first drug.
And with that, I'll turn the call over now to Vicky Hahne, our Chief Commercial Officer; to review our financial results.

Vicky Hahne

Thank you, Brian, and good afternoon, everyone. I'll provide a brief overview of our financial results for the fourth quarter and full year '23, and I invite you to review our 10-K, which will be filed later today for a more detailed discussion. Our fourth quarter net loss was $18.8 million or $0.65 per share compared to $11.6 million net loss or $0.69 per share for the fourth quarter of '22.
Net loss for the full year of 2023 was $63.8 million or $2.69 per share compared to $40.4 million net loss or $2.64 per share for the same period in 2022. Because these quarterly and full year net losses include significant noncash items, including stock-based compensation and noncash interest, we also include in our press release non-GAAP adjusted net loss for the quarter and full year ending December 31, 2023.
Our non-GAAP adjusted net loss was $17.6 million or $0.61 per share for the fourth quarter of '23 compared to non-GAAP adjusted net loss of $10.3 million or $0.61 per share for the fourth quarter of '22. Non-GAAP adjusted net loss for the full year 2023 was $57.8 million or $2.44 per share compared to non-GAAP adjusted net loss of $35 million or $2.27 per share for the full year 2022.
Research and development expenses were $18.1 million for the fourth quarter of '23 compared to $10.6 million for the fourth quarter of '22. R&D expenses for the full year '23 were $60.6 million compared to $35.3 million for the prior year. Of the approximately $25.3 million increase in R&D expenses year-over-year, $22.9 million was related to activities supporting the VIKTORIA-1 Phase 3 trial and the initiation of the Phase Ib/II clinical trial.
The remaining $2.4 million increase in R&D expense is related to increased employee and consulting expenses. General and administrative expenses were $1.6 million for the fourth quarter of '23 compared to $1 million for the same period in '22. G&A expenses for the full year of '23 were $5.6 million compared to $4.1 million for the prior year.
Of the approximately $1.5 million increase in G&A expenses, $1.1 million was related to increased employee-related expenses and $0.4 million related to professional fees and other expenses associated with compliance-related activities that support financing and clinical operations. Net cash used in operating activities for the fourth quarter of '23 was $18.5 million compared to $9.5 million for the fourth quarter of '22. This was a result of non-GAAP adjusted net loss of $17.6 million, plus approximately $900,000 of working capital changes.
Net cash used in operating activities for the full year '23 was $53.8 million compared to $36 million for the full year '22. This was a result of non-GAAP adjusted net loss of approximately $57.8 million, offset by working capital changes of approximately $3.9 million. We ended the year with approximately $180.6 million of cash, cash equivalents and short-term investments compared to $168.6 million on December 31, 2022. The increase in cash year-over-year is the result of 2 financing activities that occurred in the fourth quarter of '23 and yielded gross proceeds of $65 million, which was offset by cash used in operating activities of $53.8 million in '23.
The first financing activity included a private placement offering through a prefunded warrant arrangement, which generated $50 million in gross proceeds. The second financing activity generated gross proceeds of $15 million by accessing our at-the-market offering. We expect cash, cash equivalents and investments and available funds under our debt facility to provide adequate capital to fund current operational activities into the first half of 2026.
I will now hand the call back to Brian.

Brian Sullivan

Thank you, Vicky. Operator, could you please open the call for questions.

Question and Answer Session

Operator

(Operator Instructions) Tara Bancroft, TD Cowen.

Tara Bancroft

I was wondering if you could tell us more about the overlap of ESR1 and PIK3A mutations. And if the FDA still considers Arm C or fulvestrant alone, the best comparator for Arms A and B, now a year into the launch of elacestrant. So I'm just basically trying to gauge level of confidence in Arm B versus C endpoint or even the chances that you might go for an ESR1 wild type labeling for that subset or what? Thank you.

Brian Sullivan

Thanks for the question.
Tara. We have not seen any variation in output outcomes for patients associated with ESR1 mutation with the combination of therapy that we're evaluating in this study. And so we don't anticipate a challenge on that front. We closely collaborated with the FDA when we were developing the design of our study. We've reviewed the study with them on an ongoing basis through a series of Type B meetings where we are collaborating with them and in close contact to review, not only the clinical development, but also work associated with what we hope is a future NDA. And as far as you're changing the control, there's no discussion or consideration of that drug was recently approved cap of assets or that use fulvestrant as a control just this past few months. And so we'll certainly have data available to us to report potential outcomes in patients according to their mutational status. But we don't anticipate anticipate, as I said earlier, to find any differences or make clinically meaningful differences.
Thanks.

Vicky Hahne

You have you said of which eight are your powering to for the B versus C endpoint?
You commented on?
We haven't commented on that, but I'm looking again, we're powering the study sufficiently to support regulatory approval.

Brian Sullivan

Okay.

Vicky Hahne

Thanks so much.
Thank you.

Operator

Maury Raycroft, Jefferies. P

Maury Raycroft

Hi.
Thanks for taking my questions on. It seems like the data timing is intact and on track, is there anything else you're saying about enrollment rate? I think at one point you mentioned you aim to enroll 50% of the wild-type patients by the end of the first quarter. Wondering if you've achieved that milestone and is that something that you could announce for the wild-type cohort?
You'll have milestones associated with one of the terms of our debt facility, and we did achieve that milestone during this quarter. And so we remain on track. It's consistent with the guidance we've provided about having data on the second half of this year.
Okay, great. And done as for the Phase three readout, can you provide an estimate for how much follow-up do you think you will have by the time of the data readout?
Yes, that's a number that we'll disclose at this point. We anticipate obviously reporting the top-line data and the data readout is will be triggered by achieving sufficient events and that factors in follow-up period necessary to come get a fulsome mature set of data.
Okay.
Makes sense and done.
Lastly, another question on mutations. When you analyze the the Phase Ib data you reported similar efficacy in patients with or without PI3K mutations. But can you remind me if you looked at other mutations in the pathway including ATKAKTRM. four and P. 10 loss.
And on for the Phase three, have you had discussions with FDA on how you would evaluate patients with other non PI3K mutations.
We've done analysis of patients with these other mutations, but the numbers are small. And so we didn't feel that reporting those results would be good, scientifically rigorous enough to really discuss, but we have evaluated them and based on at least a hard reputation of the small sample sizes, we haven't seen anything that is concerning or were inconsistent with the comparable results we saw with wild type X received versus mutated pictures here. And as far as other mutations and how that might interact with the FDA, certainly when you design a clinical trial in Phase three clinical trial. You have very detailed protocol statistical analysis as well prescribed and you essentially interact with the agency quite a bit at least we did to get their feedback and to ensure that our assumptions and the statistical analysis plan, it would be satisfactory subject to review to support an NDA and nothing on that front has changed in the primary biomarker that we're using is primarily to assign patients to a study that's focusing on PIX. We see mutated patients and the study that's associated with or randomizing patients who lack a picture, we see a mutation and we're using what the picture you see mutations that have supported approval of, but we see a alpha inhibitor. So again, we're relying on an approved of picture. You see a test and have confidence that that test will support subject to review by the FDA, an NDA, our submission.
Got it that's helpful. Thanks for taking my question.
You're welcome.

Operator

Gil Blum, Needham.

Brian Sullivan

Gil, I think that was for you.

Gil Blum

Could it could go. My name was that our books are pretty severely their side, so I'm okay.
A quick question on the prostate cancer.
So just to understand, I mean, your numbers first patients are a little far from this, what kind of signs of early efficacy would the Company be looking for in that study?
I mean, Doug and responses, your PS. activity so while the study is a primary endpoint is PFS, the PFS rate at after six months of treatment. And then there are a number of secondary endpoints, which include PFS at nine and 12 months as well as evaluating PSA change. We think the most important milestone or rather endpoint is related to a radiographic progression-free survival since that's the regulatory endpoint that we would use for evaluation in a registrational study. And so we will be, I think, consistently reporting that number and it as that number matures with number of patients who have achieved that milestone was a six month milestone, nine months or 12 months milestone well conductor. That will be a rhythm that we'll have for reporting data.
That's very helpful. Maybe another detail on the enrollment here. So as like the wild-type cohort is enrolling well, any thoughts on the mutant cohort L. they enroll in tandem essentially were enrolling and screening patients who have had prior CDK4/6 as I meet criteria of screening criteria. That includes assessment of the picture, you see a status, they then get randomized. So essentially the enrollment of wild-type and mutant are occurring concurrently. And so if our wild-type is on track, then our mutant population is on track because of the way the trial enrollment is designed because that's very helpful clarification. Thanks for taking our questions.
You're welcome.

Brad Canino, Stifel.

Brad Canino

Hi, good afternoon. I'm honest, is there any way you've been able to track adherence with the prophylactic mouthwash for stomatitis mitigation in Victoria one?
Well, we do one of the primary advantages we have in managing that and monitoring compliance is when the patients come in, offer there and three week on one week off infusion. And so the treating physicians or the <unk>, our associated nurses are evaluating, but including compliance with that prophylactic and standard questionnaire. And so we have a high degree of confidence based on that. If patients aren't compliant, we'll find out. But also we reinforce the value of that prophylaxis and just as a reminder, that prophylaxis is only used and prescribed for the first two cycles of treatment as data is fairly clear that for patients who may be prone to development of mucositis. It's not in almost all cases likely to occur in the first two cycles of treatment. And so that if you that's far able to provide that prophylaxis for that first two cycles of that, the manifestation of mucositis is much, much lower after that after that period. So it's not a So requirement then for patients to remain on that prophylaxis beyond those first two cycles.
Okay. And then I'm trying to ask another enrollment question maybe in a slightly different way, because I think the continued reiteration of top line guidance for Victoria. One is going to be important for investors. I think based on the enrollment pace you see, is there anything you can share about a time point that could be passed this year where you'd reach that have sufficient enrollment to fully secure the second half guidance for the wild-type using the rate assumptions you've got for events?

Brian Sullivan

Yes, I think again, we've provided the guidance for the second half of this year.
Obviously, as we get closer to that, we can get more granular and I think we'll update that each quarter and so the closer we get, I think the more precise, more descriptive we can be. But so far, again, we monitor enrollment for monitoring the event rates and you make certain assumptions about the event rate and we're tracking to what what our assumptions are so far.
Thanks for the question.
You're welcome.

Operator

Swayampakula Ramakanth, H.C. Wainwright.

Swayampakula Ramakanth

Thank you.
This is RK from H.C. Wainwright and good afternoon. Back some good afternoon. Most of my questions have been answered. So when will the data when you're ready to come published the data from the royalties in the second half, would that and I'm just trying to figure out how would you disseminate that information and would that be a medical meeting or and do a press release and then follow-up with a medical meeting with appropriate time. It's somewhat situational depending on the timing of meetings and when the data will be cleaned and able to be released publicly. And so when when the event tussle is triggered, we'll understand whether what the gross not gross but what the data was telling us and we would finish up data cleaning at that point. Obviously, that's going on on an ongoing basis, but it would be our expectation that we would announce top line results, meaning whether or not we met statistical significance, whether this trial was positive and probably characterize and how clinically relevant those results are. But I think it would it's typical that you present these results of a Phase three study at a medical meeting. That is our that would be our current desire. But again, depending on the timing of when the data is available. We may reconsider it, but will follow, I think, practice that's been used with other other drugs, but I think it's fairly typical that if a major meeting isn't scheduled coincident with the availability of data that people will provide that top line and then wait to a medical meeting to provide the more fulsome description of the results.
Thank you.
Thanks for taking with call.
You're welcome.

(Operator Instructions) Alex Nowak, Craig-Hallum Capital.

Alex Nowak

Hey, Greg. Good afternoon, everyone. As we're getting close to the First Victoria readout here, you brought a new chief, our Chief Commercial Officer.
That's great.
You just what are the other additional investment in the commercial talent, commercial resources? Do you need to plan for here over this year?
Sure. You start to build out the team underneath Eldon which I think typically includes a person who would head up your market access person, would head up your marketing person to head up commercial operations. And with that team, you can do the planning that's necessary to lay the groundwork for obviously a lot more significant efforts once the data reads out and you're really marching towards a specific date for launch for And so yes, we factored that into the assumptions in our budget for this year. We've incorporated that in our forecast of cash requirements and they're not extraordinary either they're appropriate relative to what needs to be done and when.
Okay, that makes sense. And then can you remind us the IP position of data within breast cancer and then the potential to expand that that length within breast or certain and potentially other cancer indications?
Right?
So we have 11 different patents that have been approved for data. We have several that are pending the active pharmaceutical ingredient patent. His would provide an exclusivity period through December 34, but because get us formulated and because formulation actually is critical to being able to deliver the drug to administer the drug. We think that that will be very relevant and that patent would have an expiration date of December 39. And so we think we'll have a extended exclusive period that would potentially carry for more than 15 years post launch.
That's our plan.

Brian Sullivan

Excellent. I appreciate the update.

Operator

There are no further questions at this time. Please proceed.

Brian Sullivan

Well, we appreciate your attendance on the call, and we look forward to updating you in the future.

Operator

Thank you. Ladies and gentlemen, the conference has now ended. Thank you all for joining. You may all disconnect.
