holkira pak trialsThis morning Health Canada approved AbbVie’s HOLKIRA PAK (ombitasvir/paritaprevir/ritonavir and dasabuvir) for the treatment of patients with chronic genotype 1 hep C, including those with cirrhosis.

HOLKIRA PAK is an all-oral, short-course, interferon-free treatment. It can be taken with or without ribavirin (RBV).

In Phase 3 clinical trials, HOLKIRA PAK (with or without ribavirin) cured an overall 97 percent of genotype 1 hep C patients, and 98 percent of patients completed treatment. In Phase 2 and 3 clinical trials, the overall rates of discontinuation due to adverse reactions were low (0.2 percent).

The recommended treatment regimens and durations for HOLKIRA PAK are:




Genotype 1a, without cirrhosis HOLKIRA PAK + ribavirin 12 weeks
Genotype 1b, without cirrhosis HOLKIRA PAK 12 weeks
Genotypes 1a and 1b, with cirrhosis HOLKIRA PAK + ribavirin 12 weeks*
*24 weeks of HOLKIRA PAK + ribavirin is recommended for patients with genotype 1a-infection with cirrhosis who have had a previous null response to pegylated interferon (pegIFN) and ribavirin.
Note: HOLKIRA PAK with ribavirin is recommended in patients with an unknown genotype 1 subtype or with mixed genotype
