Brief Summary  

This is an open-label, randomized parallel design, in vivo/ex vivo, bioequivalence study in healthy, premenopausal adult female participants.

Up to 310 adult female healthy participants will be randomized (1:1) to receive either LSP-9759 or Nexplanon® to achieve 222 completed participants. After 26 weeks of treatment the implant will be removed and residual amount of etonogestrel will be assessed.

Participants who meet all study inclusion and no study exclusion criteria will be randomized to receive either LSP-9759 or Nexplanon on Study Day 1. The randomization will be stratified by site and participant BMI (<20.0, 20.0-24.9, ≥25.0 kg/m2) based on participant’s Day -1 weight.

At time of implantation, the participant must be between Day 1 (first day of menstrual bleeding) and Day 5 of the menstrual cycle, even if the participant is still bleeding.

Participants will be admitted to the clinic on Study Day -1 and will remain in the clinical for at least 72 hours after implantation of the study drug to allow for safety monitoring and PK sample collection.

Participants will also return for a total of 12 outpatient visits for safety monitoring and PK sample collection and on Study Day 183 for safety monitoring, PK sample collection and removal of the study drug implant.

A total of 21 pharmacokinetic samples (7.0 mL each) will be collected from each participant.

Pharmacokinetic samples will be taken at Pre-Dose (up to 2 hours prior to implantation) and at 2, 4, 6, 8, 12, 24 (Study Day 2), 48 (Study Day 3), 72 (Study Day 4), 96 (Study Day 5), 120 (Study Day 6), 168 (Study Day 8), 240 (Study Day 11), 336 (Study Day 15), 504 (Study Day 22), 672 (Study Day 29), 1344 (Study Day 57), 2016 (Study Day 85), 2688 (Study Day 113), 3360 (Study Day 141) and 4368 (Study Day 183) hours post dose.
