FDA approves Daklinza (daclatasvir) + sofosbuvir to treat Hepatitis C genotype 3- BMS

Bristol-Myers Squibb Company (BMS) announced that Daklinza (daclatasvir), an NS5A replication complex inhibitor, has been approved on 24 July 2015 by the FDA. This approval marks the first time patients with chronic hepatitis C virus (HCV) genotype 3 have a 12-week, once-daily, all-oral treatment option. Daklinza is indicated for use with sofosbuvir for the treatment of patients with chronic HCV genotype 3 infection. Sustained virologic response (SVR) rates are reduced in HCV genotype 3-infected patients with cirrhosis receiving this regimen. The recommended dosage of Daklinza is 60 mg in combination with sofosbuvir for 12 weeks.

The safety and efficacy of Daklinza in combination with sofosbuvir were evaluated in a Phase III clinical trial (ALLY-3) of 152 treatment-naive and treatment-experienced participants with chronic HCV genotype 3 infection. Participants received Daklinza 60 mg plus sofosbuvir 400 mg once daily for 12 weeks and were monitored for 24 weeks post treatment. The studies were designed to measure whether a participant�s hepatitis C virus was no longer detected in the blood 12 weeks after finishing treatment (sustained virologic response), suggesting a participant�s infection had been cured. Results showed that 98 percent of the treatment-naive participants with no cirrhosis of the liver and 58 percent of the treatment-naive participants with cirrhosis achieved sustained virologic response. Of the participants who were treatment-experienced, 92 percent with no cirrhosis of the liver and 69 percent with cirrhosis achieved sustained virologic response. Daklinza labeling carries a Limitations of Use statement to inform prescribers that sustained virologic response rates are reduced in HCV genotype 3 infected patients with cirrhosis. Safety information was available for approximately 1,900 patients with HCV treated with the recommended dose of Daklinza in combination with other anti-HCV drugs in clinical trials. The most common side effects of Daklinza with sofosbuvir were fatigue and headache.
