ASC618 Gene Therapy in Hemophilia A Patients

Phase 1
Recruiting
Conditions
Hemophilia A
Interventions
Biological: ASC618
Registration Number
NCT04676048
Lead Sponsor
ASC Therapeutics
Brief Summary

Currently, hemophilia A patients are managed with prophylactic or on-demand replacement therapy with recombinant FVIII or alternative therapeutics. The major challenges of current treatment regimens, such as the short half-life of hemophilia therapeutics with the need for frequent IV injections, encourage the current efforts for gene transfer therapy.

This study will evaluate the safety and preliminary efficacy of ASC618, an AAV vector encoding B-domain deleted codon-optimized human factor VIII under a synthetic liver-directed promoter
