Components of VIEKIRA XR with Ribavirin in GT1-Infected Subjects with Compensated Cirrhosis
The components of VIEKIRA XR with ribavirin were assessed in 380 subjects with genotype 1 infection and compensated cirrhosis who were treated with the components of VIEKIRA XR plus ribavirin for 12 (n=208) or 24 (n=172) weeks duration (TURQUOISE-II) [see Clinical Studies (14.1, 14.3)]. The type and severity of adverse events in subjects with compensated cirrhosis was comparable to non-cirrhotic subjects in other phase 3 trials. Fatigue, skin reactions and dyspnea occurred at least 5% more often in subjects treated for 24 weeks. The majority of adverse events occurred during the first 12 weeks of dosing in both treatment arms. Most of the adverse events were mild to moderate in severity. The proportion of subjects treated with the components of VIEKIRA XR for 12 and 24 weeks who experienced SAEs were 6% and 5%, respectively and 2% of subjects permanently discontinued treatment due to adverse events in each treatment arm.
Components of VIEKIRA XR without Ribavirin in GT1b-Infected Subjects with Compensated Cirrhosis
The components of VIEKIRA XR without ribavirin for 12 weeks was assessed in 60 subjects with genotype 1b infection and compensated cirrhosis (TURQUOISE-III) [see Clinical Studies (14.1, 14.3)]. The type and severity of adverse events and laboratory abnormalities in genotype 1b-infected subjects with compensated cirrhosis were comparable to subjects in other trials without ribavirin.
Skin Reactions
In PEARL-II, -III and -IV, 7% of subjects receiving the components of VIEKIRA XR alone and 10% of subjects receiving the components of VIEKIRA XR with ribavirin reported rash-related events. In SAPPHIRE-I and -II 16% of subjects receiving the components of VIEKIRA XR with ribavirin and 9% of subjects receiving placebo reported skin reactions. In TURQUOISE-II, 18% and 24% of subjects receiving the components of VIEKIRA XR with ribavirin for 12 or 24 weeks reported skin reactions. The majority of events were graded as mild in severity. There were no serious events or severe cutaneous reactions, such as Stevens Johnson Syndrome (SJS), toxic epidermal necrolysis (TEN), erythema multiforme (EM) or drug rash with eosinophilia and systemic symptoms (DRESS).
Laboratory Abnormalities
Serum ALT Elevations
Approximately 1% of subjects treated with the components of VIEKIRA XR experienced post-baseline serum ALT levels greater than 5 times the upper limit of normal (ULN) after starting treatment. The incidence increased to 25% (4/16) among women taking a concomitant ethinyl estradiol containing medication [see Contraindications (4) and Warnings and Precautions (5.3)]. The incidence of clinically relevant ALT elevations among women using estrogens other than ethinyl estradiol, such as estradiol and conjugated estrogens used in hormone replacemen |
