Overview
TT-034 is an investigational gene therapy developed for the treatment of chronic hepatitis C virus (HCV) infection. It utilizes a recombinant adeno-associated virus serotype 8 (AAV8) vector to deliver three short hairpin RNA (shRNA) sequences into hepatocytes. These shRNAs are designed to target and cleave highly conserved regions of the HCV RNA genome via RNA interference, thereby inhibiting viral replication. The therapy is administered as a single intravenous infusion and aims to provide long-lasting suppression or potential cure of HCV with one dose. Once inside liver cells, TT-034 continuously expresses the anti-HCV shRNAs for the lifetime of those cells[1][5][6][7]. The drug was developed by Benitec Biopharma using its ddRNAi platform technology and was tested in Phase 1/2 clinical trials but development was discontinued after demonstrating safety and proof-of-concept[3][5].
