In Brief

A Phase 3 clinical trial evaluating AAV5-hFIXco-Padua and Factor IX (FIX) for Hemophilia B. Completed, enrolled 67 participants across 33 sites in 8 countries.

Detailed 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.
