Fast Track designation is granted by the FDA to products that are developed to treat serious or life-threatening conditions and demonstrate the potential to address unmet medical needs. This designation is intended to facilitate development and expedite review of qualifying drugs. A drug that receives Fast Track designation may be eligible for more frequent meetings and communications with the FDA and rolling review of any application for marketing approval.
"Receiving Fast Track designation for Enolen is further evidence of the urgent need for new treatment options for early-stage prostate cancer. Patients living with prostate cancer deserve an alternative to active surveillance or being faced with the considerable negative side effects common with the more aggressive treatment options available today," said Cam Gallagher, President and Chief Executive Officer of Alessa Therapeutics. "We will continue to collaborate closely with the FDA to advance a new treatment option for men suffering not only from the disease itself, but who often face a heavy burden in deciding between not treating their cancer or pursuing therapies with significant health and lifestyle consequences."
Enolen utilizes novel anti-androgen eluting implants containing the FDA-approved prostate cancer compound enzalutamide. Enolen leverages Alessa’s proprietary local delivery technology which can deliver anti-androgens directly to diseased tissue in the prostate. This localized delivery can help eliminate the potential side effects of systemic anti-androgen and testosterone-lowering drugs, including sexual dysfunction, muscle mass loss, cognitive issues, metabolic syndrome and cardiovascular events.
Preclinical and clinical studies to date demonstrate that Alessa’s implant technology can deliver durable and continuous release of effective anti-cancer agents, achieving high local drug concentrations while minimizing the potential negative side effects which can result from systemic exposure.
Enolen is currently being studied in a Phase 1 trial evaluating its safety, tolerability and preliminary efficacy for localized sustained delivery of enzalutamide into the prostate. Alessa expects to present initial findings from the study in 2026.
