Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with prostate cancer on ADT for at least 3 months, with persistent vasomotor symptoms (hot flashes) and adequate organ function.

Probably not a fit

Patients with significant liver disease, severe renal impairment, or use of conflicting medications may not benefit and could be excluded from participation.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a randomized, double-blind, placebo-controlled study conducted across multiple centers to see if fezolinetant helps relieve vasomotor symptoms in men on androgen deprivation therapy for prostate cancer. Eligible participants are adults on ADT with a baseline daily hot flush score of at least 4, and a Karnofsky performance status of 70% or higher. Participants are assigned to fezolinetant 45 mg or placebo once daily for 12 weeks, with assessments at weeks 4, 8, and 12 using questionnaires, diaries, blood tests, and clinic visits. The trial aims to determine efficacy and safety through patient-reported outcomes and clinical data collected at specified intervals.

Why it matters

Potential benefit: If successful, fezolinetant could reduce vasomotor symptoms and improve quality of life for men on ADT.

How similar studies have gone: Evidence from earlier trials in other populations suggests potential benefit of similar approaches, though this exact population is novel.
