UNASSIGNED: The effect of semaglutide, a once-weekly @entity1 @entity5445 ( @entity5445 ) analog in development for @entity2175 ( @entity2175 ), on the bioavailability of a combined oral contraceptive was investigated. Postmenopausal @entity1 with @entity2175 (n   =   43) on diet/exercise        metformin received ethinylestradiol (0.03   mg)/levonorgestrel (0.15   mg) once daily for 8 days before (semaglutide-free) and during (steady-state 1.0   mg) semaglutide treatment (subcutaneous once weekly; dose escalation: 0.25   mg 4 weeks; 0.5   mg 4 weeks; 1.0   mg 5 weeks). Bioequivalence of oral contraceptives was established if 90%CI for the ratio of pharmacokinetic parameters during semaglutide steady-state and semaglutide-free periods was within prespecified limits (0.80-1.25). The bioequivalence criterion was met for ethinylestradiol area under the curve (AUC0-24   h ) for semaglutide steady-state/semaglutide-free; 1.11 (1.06-1.15). AUC0-24   h was 20% higher for levonorgestrel at semaglutide steady-state vs. semaglutide-free (1.20 [1.15-1.26]). Cmax was within bioequivalence criterion for both contraceptives. Reductions (mean        SD) in HbA1c (-1.1        0.6%) and weight (-4.3        3.1   kg) were observed. Semaglutide pharmacokinetics were compatible with once-weekly dosing; the semaglutide dose and dose-escalation regimen were well tolerated. Adverse events, mainly gastrointestinal, were mild to moderate in severity. Asymptomatic increases in mean amylase and lipase were observed. Three subjects had elevated alanine aminotransferase levels >= 3x the upper limit of normal during semaglutide/oral contraceptive coadministration, which were reported as adverse events, but resolved during follow-up. Semaglutide did not reduce the bioavailability of ethinylestradiol and levonorgestrel.

Semaglutide, a once-weekly XXXX @entity5445 analog, does not reduce the bioavailability of the combined oral contraceptive, ethinylestradiol/levonorgestrel.
