Trial Summary

The Phase 1/2 study (190-201) evaluated the efficacy and safety of a 300 mg dose of BMN 190 administered every other week (qow) to patients with CLN2. The dose and regimen for this study (190-202) are based on the results of the 190-201 study. The rationale for this phase 2 extension study is to provide patients who complete the 190-201 study with the option to continue BMN 190 treatment. The 190-202 study is an open label extension protocol to assess long-term safety and efficacy.
