FDA grants Priority Review for Daklinza (daclatasvir) sNDAs

Three applications are under review for Daklinza in combination with sofosbuvir with or without ribavirin to treat chronic hepatitis C patients with decompensated cirrhosis, post-liver transplant recurrence of HCV, and coinfection with HIV-1.

FDA will review the three Daklinza sNDAs within a 6-month timeframe.

“Hepatitis C is not a one-size-fits-all, monolithic disease. Our focus for the Daklinza-sofosbuvir regimen centers on addressing the needs of HCV patient subpopulations who need new options even in light of the extraordinary advances that have occurred in HCV treatment,” said Douglas Manion, M.D., head of Specialty Development, Bristol-Myers Squibb. “We look forward to working with the FDA toward the goal of eventually helping many difficult-to-treat HCV patients.”

Daklinza was initially approved in the US in July 2015 and is indicated for use with sofosbuvir for the treatment of patients with chronic HCV genotype 3 infection. The new sNDAs accepted by the FDA for review include data from the ALLY-1 and ALLY-2 clinical trials. ALLY-2 evaluated the once-daily 12-week combination of Daklinza and sofosbuvir for the treatment of patients with HCV coinfected with HIV-1, a patient population that historically has been challenging to treat, in large part due to the complexities of the overlapping therapeutic regimens used to treat each infection. ALLY-1 evaluated a 12-week regimen of daclatasvir and sofosbuvir once-daily with ribavirin for the treatment of patients with HCV with either advanced cirrhosis or post-liver transplant recurrence of HCV.

In May 2015, Daklinza with sofosbuvir received FDA Breakthrough Therapy Designation for HCV genotype 1 patients with advanced cirrhosis (Child-Pugh Class B or C) and those who develop genotype 1 HCV recurrence post-liver transplant. Breakthrough Therapy Designation, according to the FDA, is intended to expedite the development and review of drugs for serious or life-threatening conditions. The criteria for this designation require preliminary clinical evidence that demonstrates the drug may have substantial improvement on at least one clinically significant endpoint over available therapy.
