VIEKIRA XR(dasabuvir, ombitasvir, paritaprevir, and ritonavir)extended-release tablets(八)
of HIV-1 protease inhibitor drug resistance.
6 ADVERSE REACTIONS
The following adverse reaction is described below and elsewhere in the labeling:
Risk of Hepatic Decompensation and Hepatic Failure in Patients with Cirrhosis [see Warnings and Precautions (5.2)]
Increased Risk of ALT Elevations [see Warnings and Precautions (5.3)]
6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of VIEKIRA XR cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
If VIEKIRA XR is administered with ribavirin (RBV), refer to the prescribing information for ribavirin for a list of ribavirin-associated adverse reactions.
The safety assessment was based on data from seven clinical trials in more than 2,000 subjects who received the components of VIEKIRA XR with or without ribavirin for 12 or 24 weeks.
Components of VIEKIRA XR with Ribavirin in GT 1-Infected Subjects without Cirrhosis
The safety of the components of VIEKIRA XR with ribavirin were assessed in 770 subjects with chronic HCV genotype 1 (GT1) infection without cirrhosis in two placebo-controlled trials (SAPPHIRE-I and -II) [see Clinical Studies (14.1, 14.2)]. Adverse reactions that occurred more often in subjects treated with the components of VIEKIRA XR with ribavirin compared to placebo were fatigue, nausea, pruritus, other skin reactions, insomnia, and asthenia (see TABLE 3). The majority of the adverse reactions were mild in severity. Two percent of subjects experienced a serious adverse event (SAE). The proportion of subjects who permanently discontinued treatment due to adverse reactions was less than 1%.

Components of VIEKIRA XR with and without Ribavirin in GT1-Infected Subjects without Cirrhosis
The components of VIEKIRA XR with and without ribavirin were assessed in 401 and 509 subjects with chronic HCV infection GT1 infection without cirrhosis, respectively, in three clinical trials (PEARL-II, PEARL-III and PEARL-IV) [see Clinical Studies (14.1, 14.2)]. Pruritus, nausea, insomnia, and asthenia were identified as adverse events occurring more often in subjects treated with the components of VIEKIRA XR with ribavirin (see TABLE 4). The majority of adverse events were mild to moderate in severity. The proportion of subjects who permanently discontinued treatment due to adverse events was less than 1% for the components of VIEKIRA XR with or without |
