About

The BMN 270 clinical development program consists of multiple interventional studies designed to assess the safety and efficacy of a single infusion of BMN 270 for at least 5 years post-infusion. This long-term follow-up study is needed to help further understand the long-term safety of BMN 270 beyond 5 years and to assess the durability of efficacy.

Sex: Male

Ages: 18+ years old
