Phase
I
Principal Investigator(s)
Patrick Kiser, PhD
Objective

The purpose of the study is to evaluate the safety of the TFV/LNG intravaginal ring (IVR), TFV-only IVR, and placebo IVR, evaluate pharmacokinetics (PK) of TFV and LNG, evaluate pharmacodynamic (PD) surrogates of contraceptive efficacy of LNG, and to evaluate acceptability of the IVRs.

Description
TFV IVR is an intravaginal ring 55.0 mm in diameter, consisting of single segment of polyurethane tubing with an outer diameter of 5.5 mm and filled with white TFV-containing paste. Used for one month, the IVR delivers 8-10 mg/day TFV.

Experimental
Description
TFV/LNG IVR is an intravaginal ring 55.0 mm in diameter, consisting of two segments of polyurethane tubing with an outer diameter of 5.5 mm: a longer segment containing white TFV paste and a shorter one (20 mm) with a white LNG core. Used for one month, the IVR delivers 8-10 mg/day TFV and 20 μg/day LNG.
