No clinically significant difference on the pharmacokinetics of doravirine were observed based on age (18 to 78 years of age), sex, and race/ethnicity, mild to severe renal impairment (creatinine clearance (CLcr) >15 mL/min, estimated by Cockcroft-Gault), or moderate hepatic impairment (Child-Pugh B). The pharmacokinetics of doravirine in patients with end-stage renal disease or undergoing dialysis, severe hepatic impairment (Child-Pugh C), or <18 years of age is unknown.^L12729

No adequate human data are available to establish whether or not doravirine poses a risk to pregnancy outcomes.^L12729

It is unknown whether doravirine is present in human milk, affects human milk production, or has effects on the breastfed infant.^L12729 Because of the potential for (1) HIV-1 transmission (in HIV-negative infants), (2) developing viral resistance (in HIV positive infants), and (3) serious adverse reactions in a breastfed infant, instruct mothers not to breastfeed if they are receiving doravirine.^L12729

The safety and efficacy of doravirine have not been established in pediatric patients less than 18 years of age.^L12729

Clinical trials of doravirine did not include sufficient numbers of subjects aged 65 years and over to determine whether they respond differently from younger subjects. In general, caution should be exercised in the administration of doravirine in elderly patients, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of comorbidities or other drug therapy.^L12729

No dosage adjustment of doravirine is required in patients with mild, moderate, or severe renal impairment. Doravirine has not been adequately studied in patients with end-stage renal disease and has not been studied in dialysis patients.^L12729

No dosage adjustment of doravirine is required in patients with mild (Child-Pugh Class A) or moderate (Child-Pugh Class B) hepatic impairment. Doravirine has not been studied in patients with severe hepatic impairment (Child-Pugh Class C).^L12729

Doravirine was not carcinogenic in long-term oral carcinogenicity studies in mice and rats at exposures up to 6 and 7 times, respectively, the human exposures at the RHD.^L12729 A statistically significant incidence of thyroid parafollicular cell adenoma and carcinoma seen only in female rats at the high dose was within the range observed in historical controls.^L12729

Doravirine was not genotoxic in a battery of in vitro or in vivo assays, including microbial mutagenesis, chromosomal aberration in Chinese hamster ovary cells, and in in vivo rat micronucleus assays.^L12729

There were no effects on fertility, mating performance or early embryonic development when doravirine was administered to rats at systemic exposures (AUC) approximately 7 times the exposure in humans at the RHD.^L12729
