Study Summary

This is an open-label, single-dose, multi-center, multinational trial to demonstrate the efficacy of AMT-061 and to further describe its safety profile. The study drug is identified as AAV5-hFIXco-Padua (AMT- 061). AMT-061 is a recombinant adeno-associated viral vector of serotype 5 (AAV5) containing the Padua variant of a codon-optimized human FIX complementary deoxyribonucleic acid (cDNA) under the control of a liver-specific promoter. The pharmaceutical form of AMT-061 is a solution for intravenous infusion administered at a dose of 2 x 10\^13 gc/kg.

Primary Outcome

Adjusted ABR for Lead-in and Post-Treatment period was estimated from a repeated measures generalized estimating equations negative binomial regression model accounting for the paired design of the trial with an offset parameter to account for the differential collection periods. Treatment period was included as a categorical covariate.

Interventions
