pik3ca medical

"Updated Data from the PIK3CA Wild-Type Cohort of the Phase 3 VIKTORIA-1"

PIK3CA is a gene that helps control cell growth and survival by sending signals inside cells; when it carries certain mutations, those signals can become stuck in the “on” position and drive cancer growth. For investors, PIK3CA matters because its mutations are a biomarker used to identify patients for targeted drugs and diagnostics, affecting clinical trial design, approval chances, and potential market size for therapies aimed at those mutations.

pi3k/akt/mtor medical

"Gedatolisib, a multi-target PI3K/AKT/mTOR (PAM) inhibitor, plus fulvestrant"

A cellular signaling pathway made of proteins called PI3K, AKT and mTOR that helps control cell growth, survival and metabolism; think of it as a central control system that tells cells when to divide, store energy or self-repair. It matters to investors because drugs or diagnostics that affect this pathway are key targets in cancer and other diseases, so progress, trial results or regulatory changes around these targets can strongly influence a biotech or pharmaceutical company’s value.

fulvestrant medical

"plus fulvestrant with or without palbociclib for second-line (2L) treatment"

Fulvestrant is a prescription anti-cancer medication given by injection that treats certain hormone-driven breast cancers by blocking estrogen’s influence on tumor cells and promoting removal of the receptors those cells use to grow. Investors care about fulvestrant because clinical trial results, regulatory approvals, pricing and sales determine revenue potential and competitive position for drug makers—like whether a new product becomes a dependable new revenue engine.

palbociclib medical

"plus fulvestrant with or without palbociclib for second-line (2L) treatment"

Palbociclib is an oral cancer medicine that slows tumor growth by blocking proteins cancer cells use to multiply, acting like a temporary brake on cell division. Investors watch palbociclib because its clinical results, regulatory approvals, patent status and sales directly influence a drug maker’s revenues and valuation; positive trial data or new approvals can boost future earnings, while setbacks or generic competition can reduce a company’s market value.

hr+/her2- medical

"patients with HR+/HER2-/PIK3CA-wild type (WT) advanced breast cancer"

A cancer subtype where tumor cells have hormone receptors for estrogen and/or progesterone (HR+) but lack excess HER2 protein (HER2−). Think of receptors as locks: HR+ tumors have locks that can be targeted by hormone-blocking drugs, while HER2− means a different lock is absent, so HER2-targeted medicines won’t work. For investors this classification matters because it determines which therapies are appropriate, how large the patient market is, and which clinical trials and regulatory paths are relevant.

phase 3 medical

"updated results from the randomized, phase 3 VIKTORIA-1 trialAuthor"

Phase 3 is the late-stage clinical testing step for a new drug or medical treatment, where the product is given to large groups of patients to confirm effectiveness, monitor side effects, and compare it to standard care. Successful Phase 3 results are often the final scientific hurdle before regulators decide on approval and market launch—like passing a final exam before graduation—and can sharply change a company's valuation and future revenue prospects.

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 PI3K/AKT/mTOR (“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. More detailed information about Celcuity’s active clinical trials can be found at ClinicalTrials.gov. Celcuity is headquartered in Minneapolis. Further information about Celcuity can be found at www.celcuity.com. Follow us on LinkedIn and X.
