Official title

A Phase I,II Open-Label Dose Escalation Study to Evaluate the Safety and Efficacy of Single Doses of TT-034 for Subjects With Chronic Hepatitis C (CHC) Infection

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The study is a first in man, dose escalation study that will measure the safety and efficacy of TT-034 in the treatment of patients with chronic hepatitis C. The study is divided into 5 dose levels. Subjects will be given a single dose delivered by IV infusion. The subjects will be monitored and the data analyzed. After a set time, between 6 and 10 weeks depending on the dose level, the next set of subjects will be dosed. The study drug is a gene therapy treatment that produces molecules that destroy the Hepatitis C virus (HCV) in infected cells. Once the study drug is given, it cannot be withdrawn. Additionally, once an individual receives a dose, he or she will not be able to receive a second dose, but will remain eligible to receive most other HCV treatments.
