Post Day-7 Prasterone
Serum concentration of prasterone measured over a 24h period on Day 7 following once-daily bedtime administration of placebo or INTRAROSA1
- In 2 primary efficacy trials, daily administration of an INTRAROSA vaginal insert for 12 weeks increased mean serum Ctrough of prasterone and its metabolites testosterone and estradiol by 47%, 21%, and 19% from baseline, respectively
- This comparison based on Ctrough may underestimate the magnitude of increase in prasterone and its metabolites’ exposure because it does not take into account the overall concentration-time profile following administration of INTRAROSA
Post Day-7 Testosterone
Serum concentration of testosterone measured over a 24h period on Day 7 following once-daily bedtime administration of placebo or INTRAROSA1
- In 2 primary efficacy trials, daily administration of an INTRAROSA vaginal insert for 12 weeks increased mean serum Ctrough of prasterone and its metabolites testosterone and estradiol by 47%, 21%, and 19% from baseline, respectively
- This comparison based on Ctrough may underestimate the magnitude of increase in prasterone and its metabolites’ exposure because it does not take into account the overall concentration-time profile following administration of INTRAROSA
Post Day-7 Estradiol (E2)
Serum concentration of estradiol measured over a 24h period on Day 7 following once-daily bedtime administration of placebo or INTRAROSA1
- In 2 primary efficacy trials, daily administration of an INTRAROSA vaginal insert for 12 weeks increased mean serum Ctrough of prasterone and its metabolites testosterone and estradiol by 47%, 21%, and 19% from baseline, respectively
- This comparison based on Ctrough may underestimate the magnitude of increase in prasterone and its metabolites’ exposure because it does not take into account the overall concentration-time profile following administration of INTRAROSA
