and Mutagenesis
Glecaprevir and pibrentasvir were not genotoxic in a battery of in vitro or in vivo assays, including bacterial mutagenicity, chromosome aberration using human peripheral blood lymphocytes and in vivo rodent micronucleus assays.
Carcinogenicity studies with glecaprevir and pibrentasvir have not been conducted.
Impairment of Fertility
No effects on mating, female or male fertility, or early embryonic development were observed in rodents at up to the highest dose tested. Systemic exposures (AUC) to glecaprevir and pibrentasvir were approximately 63 and 102 times higher, respectively, than the exposure in humans at the recommended dose.
14 CLINICAL STUDIES

NS5A Inhibitor or PI-Experienced Subjects Without Cirrhosis or With Compensated Cirrhosis
GT1 MAGELLAN-1 MAVYRET for 12 (n=25) or 16 weeks (n=17)
TN=treatment naïve; PI=protease inhibitor; CKD=chronic kidney disease
PRS-TE= defined as prior treatment experience with regimens containing interferon, pegylated interferon, ribavirin, and/or sofosbuvir, but no prior treatment experience with an HCV NS3/4A PI or NS5A inhibitor.
* Treatment durations for some trial arms shown in this table do not reflect recommended dosing for the respective genotypes, prior treatment history, and/or cirrhosis status. For recommended dosing in adults [see Dosage and Administration (2.2)].
Serum HCV RNA values were measured during the clinical trials using the Roche COBAS AmpliPrep/COBAS Taqman HCV test (version 2.0) with a lower limit of quantification (LLOQ) of 15 IU/mL (except for SURVEYOR-1 and SURVEYOR-2 which used the Roche COBAS TaqMan real-time reverse transcriptase-PCR (RT-PCR) assay v. 2.0 with an LLOQ of 25 IU/mL). The primary endpoint across all clinical trials was sustained virologic response (SVR12), defined as HCV RNA less than LLOQ at 12 weeks after the end of treatment. Relapse was defined as HCV RNA ≥ LLOQ after end-of-treatment response among subjects who completed treatment. Subjects with missing HCV RNA data, such as thos |
