Achillion Pharmaceuticals, Inc. (NASDAQ:ACHN) announced additional interim results from a Phase 2 study evaluating odalasvir (also known as ACH-3102), a NS5A inhibitor, in combination with sofosbuvir, without ribavirin, for either six or eight weeks of treatment in patients with treatment-naïve genotype 1 chronic hepatitis C virus (HCV) infection. Of the patients treated for six weeks in this cross-over cohort, 100 percent (n=6/6) remained HCV RNA undetectable twelve weeks after completing therapy (SVR12). Previously, Achillion reported results from this study including 100 percent SVR24 for the initial cohorts including 12 patients treated for eight weeks and 100 percent SVR24 for 12 patients treated for six weeks.
In May 2015, Achillion announced it had granted Janssen Pharmaceuticals, Inc. (Janssen), one of the Janssen Pharmaceutical Companies of Johnson & Johnson, an exclusive, worldwide license to develop and, upon regulatory approval, commercialize HCV products and regimens containing one or more of Achillion’s HCV assets which include odalasvir, ACH-3422, and sovaprevir.
ACH-3102 – 017: Phase 2 pilot study evaluating six- and eight-weeks of treatment in combination with sofosbuvir for genotype 1 treatment-naïve HCV
Achillion conducted a Phase 2, open-label, randomized, partial-crossover study to evaluate the efficacy, safety, and tolerability of eight weeks or six weeks of odalasvir and sofosbuvir, a marketed nucleotide polymerase inhibitor, without ribavirin, in treatment-naïve genotype 1 HCV-infected patients. The primary objective of the study was determination of sustained viral response 12 weeks (SVR12) after the completion of therapy. Eighteen patients were initially enrolled, including six observational patients (group 1). Twelve patients completed eight weeks of treatment consisting of 50 mg of odalasvir and 400 mg of sofosbuvir administered once daily while observational patients received no drug during this phase of the trial. Ten of the 12 patients receiving eight weeks of treatment had genotype 1a HCV. At baseline, the median HCV RNA was 7.15 log10 (range 5.5 — 7.8 log10). Of the 12 patients, 100 percent achieved SVR24. Odalasvir and sofosbuvir were well tolerated with no significant adverse events, ECG findings, or lab abnormalities observed during treatment.
Following achievement of the pre-specified response rate of 100 percent, the six observational patients plus six additional patients (group 2) were enrolled and received six weeks of treatment consisting of 50 mg of odalasvir and 400 mg of sofosbuvir administered once daily. Median HCV RNA at baseline was 6.95 log10 (range 6.2 — 8.0 log10) and six patients had GT 1a HCV. Of the 12 patients, 100 percent achieved SVR24.
Six additional rollover patients (group 3), enrolled into the final cohort, also received six weeks of treatment consisting of 50 mg of odalasvir and 400 mg of sofosbuvir administered once daily. Baseline characteristics included five of six patients with genotype 1a HCV, four of six patients with non-CC IL28B (two patients with IL28B TT), and a median baseline HCV RNA of 6.32 log10 IU/ml (range 6.0 — 7.3 log10 IU/ml). In all, a total of 18 patients (group 2 and 3) received six weeks of treatment and all subjects, 100 percent, achieved SVR12. (Original Source)
