Official title: Study ARI114264: A Long-Term Study of the Safety and Efficacy of Dutasteride in the Treatment of Male Subjects with Androgenetic Alopecia
Trial description: This is a multicentre, open-label study to assess the safety, tolerability, and efficacy of 0.5 mg Dutasteride administered once daily for 52 weeks in men with Androgenetic Alopecia types III vertex, IV and V per the Norwood-Hamilton classification. The study consists of a Screening Phase (3 weeks prior to Baseline) and a Treatment Phase (52 weeks). A subject who completes the full course of study treatment and the final study visit (Week 52; Visit 7) will be considered as study completion.
