Fast Track for Alessa’s Prostate Cancer Therapy

Share

FDA has granted Alessa Therapeutics a fast track designation for Enolen, an experimental localized prostate cancer therapy. The designation applies to Enolen’s use in patients with low to intermediate risk, localized prostate cancer, a population for whom treatment options are often limited to active surveillance or more aggressive interventions associated with significant side effects.

The company described Enolen as a drug-eluting implant designed to deliver the anti-androgen therapy enzalutamide directly to prostate tissue. Enzalutamide is already approved as a systemic treatment for advanced prostate cancer, but Alessa’s approach aims to localize drug exposure to the prostate in order to limit the systemic side effects commonly associated with hormone-based therapies, such as sexual dysfunction, muscle loss, metabolic complications, and cardiovascular risks, according to the company.

Enolen is currently being evaluated in a Phase 1 clinical trial assessing safety, tolerability, and preliminary efficacy of sustained, localized delivery of enzalutamide in patients with localized prostate cancer. Alessa says it expects to report initial findings from the study later this year.
