**Celcuity Announces Completion of Submission of Its New Drug Application to the U.S. FDA for Gedatolisib in HR+/HER2-/*PIK3CA* Wild-Type Advanced Breast Cancer**

**MINNEAPOLIS, November 17, 2025** — Celcuity Inc. (Nasdaq: CELC), a clinical-stage biotechnology company pursuing development of targeted therapies for oncology, today announced the completion of the submission of its New Drug Application ("NDA") to the U.S. Food and Drug Administration ("FDA") for gedatolisib in hormone receptor positive ("HR+"), human epidermal growth factor receptor 2 negative ("HER2-"), advanced breast cancer ("ABC"). The NDA was submitted under the FDA's Real-Time Oncology Review ("RTOR") program, which is intended to facilitate shorter regulatory review periods. Gedatolisib previously received both Breakthrough Therapy and Fast Track designations based on promising preliminary clinical data. The submission is based on clinical data from the *PIK3CA* wild-type cohort of the Phase 3 VIKTORIA-1 clinical trial.

"This NDA submission is an important milestone, and it brings gedatolisib one step closer to becoming available for patients with HR+/HER2- advanced breast cancer," said Brian Sullivan, CEO and co-founder of Celcuity. "We look forward to working with the FDA during the NDA review process. We believe the unprecedented efficacy results and overall safety profile of the gedatolisib regimens are potentially practice changing for patients with HR+/HER2- advanced breast cancer."

The NDA submission is based on the positive clinical results for the *PIK3CA* wild-type cohort of the Phase 3 VIKTORIA-1 trial. The efficacy results established several new milestones in the history of drug development for HR+/HER2- ABC. The gedatolisib-triplet (gedatolisib, fulvestrant and palbociclib) reduced the risk of disease progression or death by 76% compared to fulvestrant based on a hazard ratio of 0.24. The median progression-free survival ("PFS") was 9.3 months with the gedatolisib-triplet versus 2.0 months with fulvestrant, an incremental improvement of 7.3 months. The gedatolisib-doublet (gedatolisib and fulvestrant) reduced the risk of disease progression or death by 67% compared to fulvestrant based on a hazard ratio of 0.33. The median PFS was 7.4 months with the gedatolisib-doublet versus 2.0 months with fulvestrant, an incremental improvement of 5.4 months.

**Gedatolisib**

Gedatolisib is an investigational, multi-target PI3K/AKT/mTOR ("PAM") inhibitor that potently targets all four Class I PI3K isoforms, mTORC1, and mTORC2 to induce comprehensive blockade of the PAM pathway.<sup>1,2,3</sup> As a multi-target PAM inhibitor, gedatolisib's mechanism of action is highly differentiated from currently approved single-target inhibitors of the PAM pathway.<sup>2</sup> Inhibition of only a single PAM component results in cross-activation of the uninhibited components, which limits the suppression of PAM pathway activity. Gedatolisib's comprehensive PAM pathway inhibition enables full suppression of the PAM pathway by minimizing the adaptive cross-activation that occurs with single-target inhibitors. Unlike single-target inhibitors of the PAM pathway, gedatolisib has demonstrated comparable potency and cytotoxicity in *PIK3CA*-mutant and wild-type breast tumor cells in nonclinical studies and early clinical data.<sup>3,4</sup>

**About RTOR**

The FDA established the RTOR program to facilitate a more efficient review process for drugs to ensure that safe and effective treatments are available to patients as early as possible, while improving review quality and engaging in early iterative communication with the applicant. To be considered for RTOR, submissions should demonstrate the following: 1) clinical evidence from adequate and well-controlled investigation that indicates the drug may demonstrate substantial improvement on a clinically relevant endpoint over available therapies; 2) easily interpreted clinical trial endpoints; and 3) no aspect of the submission is likely to require a longer review time. Additional information about RTOR can be found at: <u>https://www.fda.gov/about-fda/oncology-center-excellence/real-time-oncology-review-pilot-program</u>.

**About Celcuity**

Celcuity is a clinical-stage biotechnology company pursuing development of targeted therapies for treatment of multiple solid tumor indications. The company's lead therapeutic candidate is gedatolisib, a potent, pan-PI3K and mTORC1/2 inhibitor that comprehensively blockades the PAM pathway. Its mechanism of action and pharmacokinetic properties are differentiated from other currently approved and investigational therapies that target PI3Kα, AKT, or mTORC1 alone or together. A Phase 3 clinical trial, VIKTORIA-1, evaluating gedatolisib in combination with fulvestrant with or without palbociclib in patients with HR+/HER2- ABC has completed enrollment and the company has reported detailed results for the *PIK3CA* wild-type cohort, and has completed enrollment of patients for the *PIK3CA* mutant cohort. A Phase 3 clinical trial, VIKTORIA-2, evaluating gedatolisib plus a CDK4/6 inhibitor and fulvestrant as first-line treatment for patients with HR+/HER2- ABC is currently enrolling patients. A Phase 1/2 clinical trial, CELC-G-201, evaluating gedatolisib in combination with darolutamide in patients with metastatic castration resistant prostate cancer, is ongoing.
