Clinical Investigation of Erlotinib as an HCV Entry Inhibitor
- Conditions
- Chronic Hepatitis C InfectionHCV Genotype 1b
- Interventions
- Drug: placebo
- Registration Number
- NCT01835938
- Lead Sponsor
- University Hospital, Strasbourg, France
- Brief Summary
Chronic Hepatitis C Virus (HCV) infection is a major cause of liver cirrhosis and hepatocellular carcinoma world-wide. Current combination therapy of pegylated interferon-alfa, ribavirin and protease inhibitors is limited by resistance and substantial side effects.
The investigators identified epidermal growth factor receptor (EGFR) as host factor for HCV infection. Inhibition of kinase function of EGFR by approved inhibitor Erlotinib (TarcevaTM) broadly inhibits HCV infection of all major genotypes including viral escape variants resistant to host immune responses.
Completed preclinical proof-of-concept studies in HCV cell culture and animal model systems demonstrate that inhibition of EGFR function by Erlotinib constitutes a novel antiviral approach for prevention and treatment of HCV infection (European patent application EP 08 305 604.4, Filing date: September 26, 2008; Inserm, Paris, France and Lupberger et al. Nature Medicine 2011).
Since Erlotinib (TarcevaTM) is an established approved drug for cancer treatment and has a well characterized safety profile in humans, the aim of the study is to investigate the safety, efficacy and pharmacokinetics of Erlotinib, a first-in-class entry inhibitor, for treatment of HCV infection in a randomized placebo-controlled double blind clinical trial in patients chronically infected with HCV. Following completion, this trial will set the stage for a further investigation of entry inhibitors as antivirals in combination with standard of care or direct antivirals such as HCV protease inhibitors. Thus, this randomized clinical trial will be an important step in the development of novel urgently needed antiviral therapies overcoming resistance.

Group Intervention Description placebo placebo - 1- Erlotinib 1- Erlotinib Erlotinib is a first class HCV entry inhibitor. In this study, Erlotinib will be administered in escalating doses in sequential patient cohorts for 14 days as follows: * Dose level (DL) 1 = 50 mg / day, * Dose level (DL) 2 = 100 mg / day, and * Dose level (DL) 3 = 150 mg / day . Each Dose Level (DL) includes 4 patients (3 patients treated with Erlotinib and one patient treated with the Placebo). Dose escalation will proceed to the subsequent DL in the absence of DLT (dose-limiting toxicity) in 2 patients receiving Erlotinib.
- Primary Outcome Measures
Name Time Method Assessment of virologic response and short-term safety of Erlotinib in patients infected with HCV genotype 1b 14-day assessment study Determination of the recommended dose on the end point of dise-limiting toxicity (DLT), establishment of the maximum-tolerated dose (MTD), and response rate defined as a reduction of at least 1 log10 HCV RNA Levels after the last dose of study drug.
- Secondary Outcome Measures
Name Time Method Assessment of pharmacokinetics of Erlotinib in HCV-infected patients 14-day assessment study - Evaluate the pharmacokinetics (AUC, Cmax) of Erlotinib.
