Exhibit 99.1
Celcuity Announces That REVTORPYK™ (gedatolisib) Is Now Commercially Available In The United States
MINNEAPOLIS, September 30, 2026— Celcuity Inc. (Nasdaq: CELC), a biotechnology company focused on developing and commercializing targeted therapies for the treatment of multiple solid tumor indications, today announced that REVTORPYK™ (gedatolisib) is now commercially available in the United States for eligible patients with hormone receptor positive (“HR+”), human epidermal growth factor receptor 2 negative (“HER2-”), locally advanced or metastatic breast cancer (“ABC”) without a PIK3CA mutation detected following progression on or after treatment with at least one line of endocrine therapy in the metastatic setting. REVTORPYK was approved in combination with palbociclib and fulvestrant (“REVTORPYK triplet”) and in combination with fulvestrant (“REVTORPYK doublet”), by the U.S. Food and Drug Administration (“FDA”) on July 14, 2026.
“Our experienced commercial and medical affairs teams have been laying the groundwork for a successful launch with healthcare providers, payers, and patient advocacy partners since REVTORPYK was approved,” said Brian Sullivan, CEO and co-founder of Celcuity. “Now that REVTORPYK is commercially available, we are focused on working with physicians to bring this new treatment option to patients living with HR+/HER2- advanced breast cancer.”
As part of its commitment to patient access, Celcuity has launched the REVTORPYK Support Services program to provide financial assistance and treatment enrollment resources for physicians and eligible patients. The program offers support with insurance coverage, including access and reimbursement; and facilitates access to financial assistance, including Copay Assistance and Patient Assistance Programs. For more information, healthcare providers can visit www.revtorpykhcp.com or contact REVTORPYK Support Services at 877-4-CELCUITY (877-423-5284).
“There is an urgent need for new and differentiated treatment options for patients with HR+/HER2-, PIK3CA wild-type advanced breast cancer in the second-line setting,” said Igor Gorbatchevsky, MD, Chief Medical Officer of Celcuity. “REVTORPYK demonstrated unprecedented clinical benefit in the pivotal VIKTORIA-1 study, and we believe, provides an important new therapeutic option to address this need. We are excited now to make this new therapy available to physicians and their patients.”
Celcuity submitted a supplemental New Drug Application to the FDA in August for REVTORPYK to treat patients with HR+/HER2-, PIK3CA mutated, advanced breast cancer based on the results of Study 2 of the VIKTORIA-1 trial. If approved, physicians would have the option to prescribe REVTORPYK for patients with advanced breast cancer regardless of their PIK3CA tumor status.
About HR+/HER2- Breast Cancer
Breast cancer is the second most common cancer and one of the leading causes of cancer-related deaths worldwide.1 More than two million breast cancer cases were diagnosed globally in 2022.1 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.2 HR+/HER2- breast cancer is the most common subtype of breast cancer, accounting for approximately 70% of all breast cancers.2
About REVTORPYK (gedatolisib)
REVTORPYK is a kinase inhibitor of class I PI3K isoforms (α, β, δ, γ) and mTOR complexes mTORC1 and mTORC2, resulting in downstream inhibition of multiple effectors, including AKT.3,4,5
REVTORPYK is in development for the first-line treatment of HR+/HER2- ABC and for the second-line treatment of metastatic castration-resistant prostate cancer.
Indication Statement
REVTORPYK (gedatolisib) is a kinase inhibitor indicated in combination with fulvestrant, with or without palbociclib, for the treatment of adult patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative locally advanced or metastatic breast cancer without a PIK3CA mutation detected following progression on or after treatment with at least one line of endocrine therapy in the metastatic setting.
IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Stomatitis: REVTORPYK can cause severe stomatitis, including ulcers and oral mucositis. Stomatitis occurred in 72% of patients treated with REVTORPYK with fulvestrant and palbociclib, including Grade 3 events in 22% of patients. Stomatitis occurred in 58% of patients treated with REVTORPYK with fulvestrant, including Grade 3 events in 12% of patients. Initiate a steroid-containing, alcohol-free mouthwash prior to starting treatment with REVTORPYK and continue prophylactically during treatment. Monitor patients for signs and symptoms of stomatitis. Withhold, reduce dose, or permanently discontinue REVTORPYK based on severity.
Dermatologic Adverse Reactions: REVTORPYK can cause severe rash. Rash occurred in 30% of patients treated with REVTORPYK in combination with fulvestrant and palbociclib, including Grade 3 events in 6% of patients. Rash occurred in 40% of patients treated with REVTORPYK with fulvestrant, including 5% of patients with Grade 3 events. Monitor patients for rash and infectious sequelae. Instruct patients to limit sun exposure during REVTORPYK treatment. Withhold, reduce dose, or permanently discontinue REVTORPYK based on severity.
Hyperglycemia: REVTORPYK can cause severe hyperglycemia. Monitor fasting glucose prior to initiating treatment with REVTORPYK and periodically during treatment. Monitor HbA1c level if clinically indicated. Increased fasting glucose occurred in 46% of patients receiving REVTORPYK in combination with fulvestrant and palbociclib (Grade 3: 0.9%) and in 57% of patients receiving REVTORPYK in combination with fulvestrant (Grade 3: 1.8%). The safety of REVTORPYK has not been established in patients with Type 1 or uncontrolled Type 2 diabetes mellitus. Patients with well-controlled Type 2 diabetes may require intensified antihyperglycemic therapy and close monitoring of fasting glucose. Manage hyperglycemia with antihyperglycemic medications as clinically indicated. Evaluate fasting blood glucose and HbA1c levels prior to starting and at regular intervals during treatment. Withhold, reduce dose, or permanently discontinue REVTORPYK based on severity.
Embryo-Fetal Toxicity: Based on its mechanism of action, REVTORPYK can cause fetal harm when administered to a pregnant woman. Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with REVTORPYK and for 2 weeks after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment and for 2 weeks after the last dose.
Advise women not to breastfeed during treatment with REVTORPYK and for 2 weeks after the last dose. When REVTORPYK is used in combination, advise patients to use effective contraception during treatment and for the longest post-treatment duration recommended in the Prescribing Information of any of the individual products. Verify the pregnancy status of females of reproductive potential prior to initiating treatment.

About Celcuity
Celcuity is a biotechnology company focused on developing and commercializing targeted therapies for the treatment of multiple solid tumor indications. The company's first FDA-approved product is REVTORPYK (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, evaluated gedatolisib in combination with fulvestrant, with or without palbociclib, for the treatment of patients with HR+/HER2- ABC. Data from this trial is the basis for FDA approval of REVTORPYK for use in adult patients with HR+/HER2- ABC without a PIK3CA mutation detected following progression on or after treatment with at least one line of endocrine therapy in the metastatic setting. Results for the PIK3CA mutant cohort of the VIKTORIA-1 study have been released. Our Phase 3 clinical trial, VIKTORIA-2, is an ongoing trial incorporating two independent studies, Study 1 and Study 2, in two separate cohorts of patients with ABC who are treatment-naive in the advanced setting. Study 1 is evaluating gedatolisib in combination with palbociclib and fulvestrant as first-line treatment for patients with endocrine-resistant HR+/HER2- ABC. Study 2 is evaluating gedatolisib in combination with palbociclib and letrozole as first-line treatment for patients with endocrine-sensitive HR+/HER2- ABC. A Phase 1b/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.
