Celcuity Announces Detailed Efficacy and Safety Results from the PIK3CA Mutant Cohort of the Phase 3 Viktoria-1 Clinical Trial of Gedatolisib

Celcuity announced detailed efficacy and safety results from the PIK3CA mutant cohort of the Phase 3 VIKTORIA-1 clinical trial of gedatolisib, an investigational pan-PI3K/mTORC1/2 inhibitor, in adults with hormone receptor positive, human epidermal growth factor receptor 2 negative, PIK3CA mutated, locally advanced or metastatic breast cancer, following progression on, or after, treatment with a CDK4/6 inhibitor and an aromatase inhibitor. Gedatolisib plus fulvestrant and palbociclib (the “gedatolisib-triplet”) reduced the risk of disease progression or death by 50% vs. alpelisib plus fulvestrant (HR=0.50; 95% CI: 0.37–0.68; p. Gedatolisib plus fulvestrant (the “gedatolisib-doublet”) reduced the risk of disease progression or death by 49% vs. alpelisib plus fulvestrant (HR=0.51; 95% CI: 0.33–0.79; descriptive p=0.0013). Median PFS was 11.3 months with the gedatolisib-doublet versus 5.6 months with alpelisib plus fulvestrant. Gedatolisib regimens demonstrated robust and durable responses: 48.9% objective response rate (“ORR”) and median duration of response (“DoR”) of 15.7 months for the gedatolisib-triplet and 35.7% ORR and median DoR of 24.2 months for the gedatolisib-doublet. The safety data and study treatment discontinuation rates for the gedatolisib-triplet and -doublet were consistent with previously reported data from the PIK3CA wild-type cohort of VIKTORIA-1. The gedatolisib-triplet and -doublet were generally well tolerated in the trial with mostly low-grade treatment-related adverse events (“TRAEs”). The most common Grade 3+ TRAEs for the gedatolisib-triplet, the gedatolisib-doublet, and alpelisib plus fulvestrant groups included neutropenia (58.8%, 0%, and 0.7% of patients, respectively); stomatitis (16.3%, 5.8%, and 5.3% of patients, respectively); rash (6.5%, 5.8%, and 15.1% of patients, respectively); and hyperglycemia (2.6%, 0%, and 14.5% of patients, respectively). TRAEs led to the discontinuation of study treatment in 2.6% of patients in the gedatolisib-triplet group, 3.8% in the gedatolisib-doublet group, and 7.1% in the alpelisib plus fulvestrant group. One Grade 5 TRAE in the gedatolisib-triplet group, which was related to palbociclib, was reported, no Grade 5 TRAEs were reported in the gedatolisib-doublet group, and two Grade 5 TRAEs were reported in the alpelisib plus fulvestrant group. Overall survival, a key secondary endpoint in VIKTORIA-1, while immature at the time of the analysis, showed promising trends for both the gedatolisib-triplet and -doublet. Celcuity intends to submit these data to the U.S. Food and Drug Administration as a supplemental New Drug Application and to submit VIKTORIA-1 data to other regulatory authorities following the sNDA submission. The FDA has granted Priority Review of Celcuity’s New Drug Application for gedatolisib in patients with HR+/HER2-/PIK3CA wild-type ABC and assigned a Prescription Drug User Fee Act goal date of July 17, 2026. VIKTORIA-1 is a Phase 3 open-label, randomized clinical trial to evaluate the efficacy and safety of gedatolisib in combination with fulvestrant, with or without palbociclib, in adults with HR+/HER2- ABC whose disease progressed on or after prior CDK4/6 therapy in combination with an aromatase inhibitor. The trial enrolled 701 subjects regardless of PIK3CA status while enabling separate evaluation of subjects according to their PIK3CA status. For the PIK3CA MT cohort, 350 subjects who met eligibility criteria and had confirmed PIK3CA mutations were randomly assigned (3:3:1) to receive a regimen of either the gedatolisib-triplet, alpelisib and fulvestrant, or the gedatolisib-doublet. Gedatolisib is an investigational, multi-target PAM inhibitor that potently targets all four class I PI3K isoforms, mTORC1, and mTORC2 to induce comprehensive blockade of the PAM pathway. As a multi-target PAM inhibitor, gedatolisib’s mechanism of action is highly differentiated from currently approved single-target inhibitors of the PAM pathway. Inhibition of only a single PAM component gives tumors an escape mechanism through cross-activation of the uninhibited targets. Gedatolisib’s comprehensive PAM pathway inhibition ensures full suppression of PAM activity by eliminating adaptive resistance cross-activation that occurs with single-target inhibitors. Unlike single-target inhibitors of the PAM pathway, gedatolisib has demonstrated equal potency and comparable cytotoxicity in PIK3CA-mutant and -wild-type breast tumor cells in nonclinical studies and early clinical data.

Celcuity’s Phase 3 VIKTORIA-2 Trial of Gedatolisib as a First-Line Treatment for HR+/HER2- Advanced Breast Cancer Expanding to Include Endocrine-Sensitive Patients

Celcuity Inc. announced updates to the Phase 3 VIKTORIA-2 clinical trial of gedatolisib as a first-line treatment for patients with hormone receptor positive (“HR+”), human epidermal growth factor receptor 2 negative (“HER2-”) locally advanced or metastatic breast cancer (“ABC”). Following last year’s announcement and subsequent data presentation demonstrating clinically meaningful improvement in progression-free survival (“PFS”) for patients treated with gedatolisib combined with palbociclib and fulvestrant compared to those treated with fulvestrant in the PIK3CA wild-type (“WT”) cohort of the VIKTORIA-1 Phase 3 study, several important elements of the VIKTORIA-2 clinical trial protocol have been amended. First, in addition to evaluating patients in the first-line setting with endocrine-resistant HR+/HER2- ABC, VIKTORIA-2 will now include a separate study to evaluate the safety and efficacy of patients in the first-line setting who have endocrine-sensitive HR+/HER2- ABC. Second, patients will be assigned manually according to their endocrine sensitivity status to either Study 1 (endocrine-resistant) or Study 2 (endocrine-sensitive) and subsequently be randomized to a treatment arm. Third, efficacy analyses for both Study 1 and Study 2 of VIKTORIA-2 will evaluate the entire intent-to-treat population (combined WT and mutant type (“MT”)) enrolled in their respective study. Each study will have independent statistical analysis plans that will include separate primary endpoints. The primary endpoints for the VIKTORIA-2 clinical trial are PFS, per RECIST 1.1 criteria, as assessed by blinded independent central review (“BICR”). Prior to finalizing the amended Phase 3 trial design, Celcuity conducted a Type B meeting with the U.S. Food and Drug Administration (the “FDA”) to obtain their feedback and to gain alignment on these planned amendments. For patients with endocrine-sensitive HR+/HER2- advanced breast cancer who received gedatolisib in combination with palbociclib and letrozole in our Phase 1b clinical trial, median progression free survival was 48.6 months, median overall survival was 77.3 months, and the objective response rate was 79%. Results from the PIK3CA wild-type and mutation cohort of our VIKTORIA-1 study demonstrated the benefit of gedatolisib combination treatment in HR+/HER2- ABC in the second-line setting. Developing the gedatolisib triplet for nearly all patients in the first-line setting, irrespective of their endocrine sensitivity or PIK3CA status, offers the potential to advance the standard of care for the approximately 90,000 women each year who are diagnosed with late-stage HR+/HER2- ABC. To support its long-term lifecycle development plan, Celcuity also announced that it submitted to the United States Patent and Trademark Office (“USPTO”) its first patent application for a subcutaneous formulation of gedatolisib that would enable a patient to receive gedatolisib as an injection as an alternative to an infusion. Development of the subcutaneous gedatolisib formulation is ongoing with the goal of demonstrating clinical equivalence to the current intravenous formulation of gedatolisib. The subcutaneous formulation is aimed to support potential future indications for gedatolisib regimens that may result in duration of treatment periods greater than several years. Breast cancer is the second most common cancer and one of the leading causes of cancer-related deaths worldwide. More than two million breast cancer cases were diagnosed globally in 2022. While survival rates are high for those diagnosed with early breast cancer, only approximately 30% of patients who are diagnosed with or who progress to metastatic disease are expected to live five years after their diagnosis. HR+/HER2- breast cancer is the most common subtype of breast cancer, accounting for approximately 70% of all breast cancers. Three interconnected signaling pathways, estrogen, cyclin D1-CDK4/6, and PI3K/AKT/mTOR (“PAM”), are primary oncogenic drivers of HR+/HER2- ABC. Therapies inhibiting these pathways are approved and used in various combinations for advanced breast cancer. Currently approved inhibitors of the PAM pathway for breast cancer target a single PAM pathway component, such as PI3Ka, AKT, or mTORC1. However, resistance to CDK4/6 inhibitors and current endocrine therapies develops in many patients with advanced disease. Optimizing the inhibition of the PAM pathway is an active area of focus for breast cancer research. VIKTORIA-2 is a Phase 3, global, open-label, randomized, clinical trial designed to evaluate the efficacy and safety of gedatolisib plus palbociclib and endocrine therapy as first-line treatment for patients with HR+/HER2- ABC. Patients will be assigned manually according to their endocrine sensitivity status to either Study 1 (endocrine-resistant) or Study 2 (endocrine-sensitive) and subsequently be randomized 1:1 to either investigational treatment or standard-of-care control. Study 1 is expected to enroll approximately 440 patients with treatment-naïve endocrine-resistant ABC whose cancer progressed while receiving or within 12 months of completing adjuvant endocrine therapy. The trial will evaluate the efficacy and safety of gedatolisib combined with palbociclib and fulvestrant (Arm A) compared to ribociclib combined with fulvestrant (Arm B). Study 2 is expected to enroll approximately 740 subjects with treatment-naïve endocrine-sensitive ABC whose cancer relapsed or progressed 12 months or more after completion of adjuvant endocrine therapy, or those with de novo metastatic disease without prior endocrine therapy exposure. The trial will evaluate the efficacy and safety of gedatolisib combined with palbociclib and letrozole (Arm C) compared to ribociclib combined with letrozole (Arm D). The clinical trial primary endpoints for the VIKTORIA-2 clinical trial are PFS, per RECIST 1.1 criteria, as assessed by BICR. This global trial is expected to enroll subjects at up to 200 clinical sites across North America, Europe, and Asia-Pacific. Gedatolisib is an investigational, multi-target PAM inhibitor that potently targets all four class I PI3K isoforms, mTORC1, and mTORC2 to induce comprehensive blockade of the PAM pathway.
