MINNEAPOLIS, MN / ACCESSWIRE / May 8, 2023 / Celcuity Inc. (NASDAQ:CELC), a clinical-stage biotechnology company focused on development of targeted therapies for oncology, today announced publication of an abstract reporting updated results for treatment-naïve patients from the Phase 1b study of gedatolisib, a pan-PI3K/mTOR inhibitor, in combination with palbociclib and letrozole in women with HR+/HER2- advanced breast cancer (ABC). A poster will be presented at the 2023 European Society for Medical Oncology (ESMO) Breast Cancer Annual Congress, which is being held May 11-13, 2023 in Berlin, Germany.
In the poster presentation, updated efficacy and safety data in treatment-naïve patients from Escalation Arm A and Expansion Arm, with a June 29, 2022 database lock and median progression-free survival (mPFS) and duration of response (DOR) updated as of March 16, 2023, will be reported. For Expansion Arm A, median PFS was 48.6 months (n=30), and the objective response rate (ORR) was 85% (n=26, measurable and evaluable disease). When treatment naïve patients from both arms are combined, mPFS was 48.6 months (n=41) and ORR was 79% (n=33, measurable and evaluable disease).
Poster presentation details are provided below.

Gedatolisib is an investigational, pan-PI3K and mTOR inhibitor with low nanomolar potency for all Class I PI3K isoforms and mTORC1 and mTORC2. Its mechanism of action and pharmacokinetic properties are highly differentiated from other therapies that target PI3K or mTOR alone or together. Inhibiting all four Class I PI3K isoforms and mTOR limits the potential development of drug resistance compared to isoform-specific PI3K or mTOR specific inhibitors. A robust response rate and a manageable side effect profile were reported for a Phase 1b clinical trial that evaluated gedatolisib in combination with palbociclib and endocrine therapy in patients with HR+/HER2- advanced breast cancer. A Phase 3 clinical trial, VIKTORIA-1, evaluating gedatolisib in combination with fulvestrant with or without palbociclib in patients with HR+/HER2- advanced breast cancer is currently enrolling patients.
Celcuity is a clinical-stage biotechnology company focused on development of targeted therapies for treatment of multiple solid tumor indications. The company's lead therapeutic candidate is gedatolisib, a potent, pan-PI3K and mTOR inhibitor. Its mechanism of action and pharmacokinetic properties are highly differentiated from other currently approved and investigational therapies that target PI3K or mTOR 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- advanced breast cancer is currently enrolling patients. More detailed information about the VIKTORIA-1 study can be found at ClinicalTrials.gov. The company's CELsignia companion diagnostic platform is uniquely able to analyze live patient tumor cells to identify new groups of cancer patients likely to benefit from already approved targeted therapies.
