Thank you, Apoorva. Good afternoon, everyone, and thank you for joining our third quarter operating and financial update conference call. The past few months were busy and fruitful ones for Celcuity. We made significant progress achieving a number of clinical and regulatory milestones while also significantly bolstering our balance sheet. These achievements lay the groundwork for us to potentially establish Get It Solicit as a new standard of care second-line therapy for patients with HR-positive, HER2-negative, advanced breast cancer. Amongst the key clinical and regulatory milestones achieved, first, we released top-line data results from the PIK3CA wild-type cohort of the Phase III VICTORIA-one study and then subsequently presented detailed efficacy and safety results for this study at a late-breaking oral presentation at the European Society for Medical Oncology, or ESMO, Congress. We also presented at this ESMO Congress updated clinical results from the phase one portion of a clinical trial evaluating getetelicib in combination with darolutamide and then with metastatic castration-resistant prostate cancer. And third, we completed enrollment of the '6 or during Q2 'twenty-six. And fourth, the FDA accepted our request to submit our new drug application or NDA under their real-time oncology review program. Brigadatilissa based on the results from the PIK3CA wild-type cohort of the VICTORIA-one trial, and we expect to complete the submission this quarter. And then fifth, to strengthen our balance sheet we completed concurrent offerings of convertible notes, common stock, and prefunded warrants which resulted in net proceeds of approximately $287 million. We also amended our term loan facility within Novartis Capital Partners and Oxford Finance to increase the total term loan facility size to $500 million including $350 million in committed capital and up to $150 million at the mutual discretion of Celcuity and its lenders. Future draws of committed capital under the facility are subject to the achievement of certain milestones. The most consequential milestone of the quarter for Cuity was, of course, the release of positive data from the PIK3CA wild-type cohort of the VICTORIA-one trial. And we've discussed previously the historic nature of the results and the new milestones they achieved HR-positive HER2-negative advanced breast cancer. But to recap, median progression-free survival, or PFS, for the gadgets elicit triplet which is gadgetolitinib, palbociclib, and fulvestrant. Was 9.3 months. Compared to only 2 months for fulvestrant. Which is a 7.3-month incremental improvement in median PFS. The hazard ratio was 0.24. For the gadgetolitinib doublet, is gaditalisib and fulvestrant, median PFS was 7.4 months versus 2.0 months with fulvestrant. A 5.4-month incremental improvement in median PFS. And the hazard ratio was 0.33. These results set several new benchmarks in HR-positive HER2-negative advanced breast cancer. The hazard ratios for both again, if those are triplet and doublet are more favorable than have ever been reported by any Phase III trial patients with HR-positive HER2-negative ABC. The 7.3 and 5.4 months incremental improvements in median PFS with the gonadotilus and triplet and doublet over fulvestrant, respectively. Are higher than have ever been reported by any Phase III trial for patients with HR-positive HER2-negative advanced breast cancer receiving at least their second line of endocrine therapy. And gaditalisib is the first inhibitor that targets the PI3K AKT mTOR pathway to demonstrate positive Phase III results in patients with its HR-positive HER2-negative PIK3CA wild-type breast cancer whose disease progressed on or after treatment with a CDK4six inhibitor. As a follow-up, reported among other things, to the release of the top-line data in July, additional data were released at a late-breaking oral presentation in October at ESMO. Now in this presentation, that the objective response rate of the genitilus triplet was 32% compared to 1% with fulvestrant, and the median duration of response was 17.5 months, and that the objective response rate of the gadgetolitinib doublet was 28% and the median duration of response was 12.0 months. Median duration of response for fulvestrant was not determinable because there was only one objective response. And these results also established new benchmarks. The median duration of response and the incremental improvement in the objective response rate relative to control the getetelicit triplet and doublet are the highest reported for an endocrine therapy-based regimen. In second-line, HR-positive HER2-negative advanced breast cancer. Additionally, the results demonstrated the clinical benefit of the gantalizumab regimens was consistent across patient subgroups. And one patient subgroup of note patients enrolled in The United States and Canada, achieved median PFS of 19.3 months with a gadathilicit triplet and 14.9 months with the gadatholizumab doublet. The ESMO presentation also provided detailed safety results that showed the gadathalisib triplet N doublet were generally well tolerated in the trial with mostly low-grade treatment-related adverse events. Study treatment discontinuation due to treatment-related adverse events was reported in 2.3% of patients treated with again, least a triplet, and 3.1 months of patients with the gadatholicit doublet. Now in the presentation of results from the PIK3CA wild-type cohort, of the VICTORIA-one study at ESMO, additional data from a Phase 1b clinical trial that evaluated gabatolizumab patients with HR-positive HER2-negative advanced breast cancer was included. And the analyses reported efficacy data from patients who were treated with the same drug regimen evaluated in the VICTORIA-one study. Ganatolizumab combined with fulvestrant and palbociclib. Now these patients were included from the escalation arm B, and expansion arms B, C, and D of the phase 1B study. Median PFS and the Objective Response Rate, or ORR, assessed in subgroups of patients according to their PIK3CA status. For the 30 analyzed patients with PIK3CA mutant tumors, median PFS was 14.6 months, and the ORR in response of valuable patients was 48%. For the 60 patients with PIK3CA wild-type tumors, median PFS was 9 months, and the ORR in response to viable patients was 41%. Now let's turn over to our VICTORIA-two study, which is a phase three clinical trial evaluating genitelisib plus a CDK4six inhibitor and fulvestrant as first-line treatment for patients with HR-positive, HER2-negative, advanced breast cancer who are endocrine therapy resistant. We dosed the first patient for this study in late July, and enrollment is ongoing. We believe the positive results from the PIK3CA wild-type cohort of our VICTORIA-one study are as well for the potential efficacy of gadathalicit triplet they induce in this patient population. Now let's turn to our Phase III clinical trial that is evaluating getasilisib in combination with darolutamide in men with metastatic castration-resistant prostate cancer. We presented detailed data the Phase I portion of the study at a poster presentation at ESMO. And in this portion of the Phase III study, 38 patients were randomly assigned to receive standard doses of genafilisib in either 120 milligrams of genifilisib in arm one or 180 milligrams of genifilisib in arm two. Among the 38 patients enrolled, 61% had received one line of prior systemic therapy, 39% had received at least two or more lines of prior therapy. The Phase I data set utilized in August 15, 2025, data cutoff and median duration follow-up was 9 months. The six-month radiographic PFS or RPFS rate was 67%, And the median radiographic progression-free survival for patients was 9.1 months from both arms combined. For patients treated with 120 milligrams of getitalisib, the six-month RPFS rate was 74%, and the median RPFS was 9.5 months. For patients treated with 180 milligrams of genitulisib, the six-month PFS rate was 61% and the medium RPFS 7.4 months. And these results compare favorably to historic results for patients with MCR PC who were treated with an androgen receptor inhibitor as second-line treatment. The combination of geta darolutamide were generally well tolerated in the trial with mostly low-grade treatment-related adverse events. No dose-limiting toxicities were observed in either arm. The only grade III treatment-related adverse events for patients from both arms combined included rash, in about 5.3% of patients, stomatitis in 2.6% of patients, and pruritus in 2.6% of patients as well. No grade three hyperglycemia was reported. Additionally, though patients discontinued the study treatment due to an adverse event, Now as we near what we hope is an FDA approval for get 2026, our efforts to prepare for the potential launch of have ramped up per our strategic launch plan. Foundational to these efforts was the additional cash we raised and the enhanced financial flexibility of $500 million term loan facility provides us. We began laying the groundwork for a potential Get Us With Sub launch 18 months ago, and we've since made significant progress building the organization internal systems required to operate as a commercial states company. As planned, once the VICTORIA-one wild-type data was in hand, our commercial launch preparation efforts significantly accelerated. Except for the field sales force, we've mostly completed hiring of the individuals needed to execute the launch. And we're very fortunate to have attracted an incredibly talented group of individuals have a strong track record of successfully launching novel oncology therapeutics. Our sales management and customer operations groups have defined our regional and sales territories and our go-to-market objectives for each one. Medical science liaison and KOL engagement teams have done a great job of exchanging scientific information with key opinion leaders and community practice leaders and obtaining important insights and feedback from them. Now key efforts today include extensive outreach across the country to the payers and population health decision-makers in various treatment settings, including health systems integrated delivery networks, and community oncology practices that will play a key role in providing oncologists access together to listen to their patients. We've made strong progress engaging with these decision-makers and we're very pleased with the feedback and enthusiastic response these efforts have yielded. We're also very encouraged by the results of research we have fielded to gauge the willingness of community and academic oncologists to prescribe Ganaxlica should it get approved. And these results make us optimistic about the possibility of establishing geditsilicit as the new standard of care. The second-line setting for HR-positive, HER2-negative, advanced breast cancer in the wild-type patient population. Now in light of this feedback, we believe obtaining majority market share on the setting is not only achievable but potentially too conservative. Based on analysis of published epidemiological data, estimate there are 37,000 patients in The US with HR-positive HER2-negative advanced breast cancer who've progressed after treatment with a CDK4six inhibitor. Now using internal duration of treatment estimates and pricing assumptions can consistent with currently available novel therapeutics for breast cancer, we estimate the total addressable market for Ogedegylus in the second-line setting is $5 billion to $6 billion. And given the significant penetration our research is suggesting we can achieve we believe it's reasonable to estimate that a second-line wild-type indication or second-line indication in general for get us to listen can potentially generate peak revenues of $2.5 billion to $3 billion. The progress we've made to date is encouraging and exciting, We look forward to providing you updates over the next few quarters. We believe the resources we've raised will enable us to advance multiple potential blockbuster indications in breast and prostate cancer while also aggressively preparing and potentially launching gabapalizumab commercially should we receive FDA approval. Gadasolizumab is well positioned to address critical needs in the second-line space, with its unique mechanism of action and potential first-in-class and best-in-class safety and efficacy profile. I'd like to now hand the call over to Vicky to review our finances.
