Efficacy and Safety of Fezolinetant for Treatment of Moderate to Severe Vasomotor Symptoms Associated With Androgen-Deprivation Therapy in Men With Prostate Cancer (FLASH): A Phase 2 Study
This study is for men with prostate cancer who are experiencing hot flashes due to treatments that lower testosterone. Hot flashes can affect your quality of life and make it harder for patients to continue their treatment, so researchers want to find a better way to manage them. The study is testing a drug called fezolinetant, which might help reduce hot flashes without using hormones. Fezolinetant is a drug that is currently approved for the treatment of hot flashes in menopausal women.
• Age ≥ 18 years Men who are currently receiving Androgen Deprivation Therapy (ADT) for the treatment of prostate cancer. ADT is defined by a history of orchiectomy, or ongoing usage of gonadotropin-releasing hormone agonists or antagonists (e.g. leuprolide, degarelix, relugolix). Men receiving Androgen Receptor Pathway Inhibitors (ARPI) such as abiraterone, enzalutamide, apalutamide, and darolutamide are eligible.
• Patients must be on a stable dose of all hormonal therapies for at least 28 days prior to registration and must not be planning to discontinue this therapy for at least 42 days following registration. Additional ARPI agents (e.g. abiraterone or enzalutamide) are allowed to be added during the Extension Phase of the trial, but not during the Treatment Phase.
• Patients receiving radiation therapy during the study period are eligible. An eligible patient must have bothersome hot flashes for ≥ 7 days prior to consent, resulting in an average of four or more hot flashes per day of sufficient severity to cause the patient to seek therapeutic intervention.
• Life Expectancy of 6 months or greater. Language: In order to complete the mandatory participant-completed measures, participants must be able to speak and read English.
