Gedatolisib FDA Regulatory Timeline and Events
Gedatolisib is a drug developed by Celcuity for the following indication: HR+ / HER2- Metastatic Breast Cancer.
This drug is under review by the U.S. Food and Drug Administration (FDA).
Below is a timeline of key regulatory milestones for this therapy.
- Drug:
- Gedatolisib
- Announced Date:
- July 28, 2025
- Indication:
- HR+ / HER2- Metastatic Breast Cancer
Announcement
Celcuity Inc announced positive topline results from the PIK3CA wild-type cohort of the Phase 3 VIKTORIA-1 clinical trial evaluating gedatolisib plus fulvestrant with and without palbociclib versus fulvestrant in adults with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, PIK3CA wild-type, locally advanced or metastatic breast cancer, following progression on, or after, treatment with a CDK4/6 inhibitor and an aromatase inhibitor.
AI Summary
Celcuity reported top results from the PIK3CA wild-type group of its Phase 3 VIKTORIA-1 trial. The study tested gedatolisib plus fulvestrant, with or without palbociclib, against fulvestrant alone in HR+/HER2- advanced breast cancer after progression on CDK4/6 and aromatase inhibitor therapy.
The gedatolisib triplet cut the risk of disease progression or death by 76% versus fulvestrant (hazard ratio 0.24; p<0.0001), boosting median progression-free survival to 9.3 months versus 2.0. The gedatolisib doublet lowered risk by 67% (HR 0.33; p<0.0001), raising median PFS to 7.4 months.
Both gedatolisib regimens showed good safety, with fewer treatment-related dropouts and lower rates of hyperglycemia and stomatitis than seen in earlier studies or approved regimens.
Celcuity will present full wild-type results at a medical conference later this year. It aims to file an NDA for gedatolisib in Q4 2025 and expects mutation-cohort data by the end of that year.

Announcement
Celcuity Inc reported topline results from the PIK3CA wild-type cohort of the Phase 3 VIKTORIA-1 trial, which evaluated gedatolisib plus fulvestrant with and without palbociclib versus fulvestrant.
AI Summary
Celcuity Inc. reported positive topline results from the PIK3CA wild-type group of the Phase 3 VIKTORIA-1 trial, which tested gedatolisib plus fulvestrant with and without palbociclib versus fulvestrant alone in HR-positive, HER2-negative advanced breast cancer. The gedatolisib triplet cut progression or death risk by 76% (HR=0.24; p<0.0001), extending median progression-free survival (PFS) to 9.3 months versus 2.0 months. The gedatolisib doublet reduced risk by 67% (HR=0.33; p<0.0001), with median PFS of 7.4 months versus 2.0 months.
These hazard ratios and PFS gains are unprecedented in this setting. Both gedatolisib regimens were well tolerated, with fewer treatment-related discontinuations and lower rates of hyperglycemia and stomatitis than seen in prior studies of approved drug combinations for similar patients.
Celcuity will present full data at a medical conference later this year and expects to file a New Drug Application in the U.S. in the fourth quarter of 2025. Topline results for the PIK3CA mutation cohort are anticipated by the end of 2025.

- Announced Date:
- July 24, 2025
- Indication:
- HR+ / HER2- Metastatic Breast Cancer
Announcement
Celcuity Inc announced that the first patient has been dosed in VIKTORIA-2, its Phase 3 clinical trial evaluating gedatolisib plus a CDK4/6 inhibitor and fulvestrant as first-line treatment for patients with HR+/HER2- advanced breast cancer ("ABC") who are endocrine therapy resistant.
AI Summary
Celcuity Inc. has dosed the first patient in VIKTORIA-2, its Phase 3 trial testing gedatolisib with a CDK4/6 inhibitor plus fulvestrant as a first-line treatment for endocrine therapy–resistant HR-positive, HER2-negative advanced breast cancer. Gedatolisib is an investigational drug that blocks multiple targets in the PI3K/AKT/mTOR pathway to stop cancer cell growth.
In an earlier Phase 1b study, patients treated with gedatolisib, palbociclib, and letrozole saw a median progression‐free survival of 48.6 months, overall survival of 77.3 months, and a 79% response rate. These results suggest that comprehensive inhibition of this pathway could help treatment‐naïve patients whose disease no longer responds to standard endocrine therapies.
VIKTORIA-2 will enroll about 638 participants worldwide, assigning them to gedatolisib plus fulvestrant and either ribociclib or palbociclib versus fulvestrant plus a CDK4/6 inhibitor. The primary goal is to measure progression‐free survival separately in tumors with and without PIK3CA mutations, aiming to bring a new first‐line option to patients.

Announcement
Celcuity Inc. announced preliminary clinical data for gedatolisib in two early phase clinical trials. Gedatolisib is a multi-target inhibitor that addresses all four class I PI3K isoforms and the mTOR complexes mTORC1 and mTORC2 to induce comprehensive blockade of the PI3K/AKT/mTOR ("PAM") pathway.
AI Summary
Celcuity Inc. announced preliminary clinical data for gedatolisib in two early phase clinical trials. Gedatolisib is a multi-target inhibitor that blocks all four class I PI3K isoforms and both mTOR complexes, mTORC1 and mTORC2, to stop the PI3K/AKT/mTOR pathway. This comprehensive blockade is aimed at stopping cancer growth. In a Phase 1 trial for men with metastatic castration-resistant prostate cancer, combining gedatolisib with darolutamide, researchers observed a 66% six-month radiographic progression free survival rate. In a Phase 2 trial involving patients with HER2-positive metastatic breast cancer, the combination of gedatolisib with trastuzumab-pkrb led to a 43% objective response rate. Importantly, no patients stopped treatment due to side effects from gedatolisib, highlighting its good tolerability so far.

Announcement
Celcuity Inc. announced overall survival (OS) data from two patient cohorts evaluated in a Phase 1b trial with gedatolisib, a pan-PI3K/mTORC1/2 inhibitor, in combination with palbociclib and either letrozole or fulvestrant, in patients with HR+, HER2-advanced or metastatic breast cancer.
AI Summary
Celcuity Inc. recently announced overall survival data from a Phase 1b trial evaluating gedatolisib, a pan-PI3K/mTORC1/2 inhibitor, in combination with palbociclib and either letrozole or fulvestrant for treating HR+, HER2– advanced or metastatic breast cancer. The study focused on two patient groups. One group, consisting of patients who were treatment-naïve in the advanced setting, achieved a median overall survival of 77.3 months. In contrast, patients who had previously been treated with a CDK4/6 inhibitor showed a median overall survival of 33.9 months.
According to Celcuity’s Chief Medical Officer, these findings are encouraging and compare favorably to published data for current first- and second-line treatments. The results will be presented in a poster session at the upcoming San Antonio Breast Cancer Symposium, highlighting a strategy that blocks the ER, CDK4/6, and PI3K/AKT/mTOR pathways simultaneously.

Announcement
Celcuity Inc. announced that it plans to initiate a Phase 3 clinical trial to evaluate gedatolisib plus a CDK4/6 inhibitor and fulvestrant as first-line treatment for patients with HR+/HER2- advanced breast cancer ("ABC") who are endocrine therapy resistant. In conjunction with its plan to conduct this study, Celcuity today entered into an amendment to an existing debt facility agreement and received an additional term loan of approximately $62 million.
AI Summary
Celcuity Inc. announced plans to launch a Phase 3 clinical trial to investigate a new first‐line treatment for patients with HR+/HER2- advanced breast cancer who are resistant to endocrine therapy. The study will test a combination of gedatolisib with fulvestrant and a CDK4/6 inhibitor, with investigators having the choice between ribociclib or palbociclib. The trial aims to compare this new treatment approach against the current standard of care, addressing a pressing need for better therapies in resistant breast cancer cases.
Alongside the trial announcement, Celcuity amended an existing debt facility agreement and secured an additional term loan of approximately $62 million. The extra financing is expected to accelerate the trial’s initiation and support the company’s continued development of targeted therapies against advanced breast cancer.
