Comparison of Two Intrauterine Devices (IUDs) Among Cape Town HIV-positive Women

Comparison of Two Intrauterine Devices (IUDs) Among Cape Town HIV-positive Women: A Randomized Controlled Trial Assessing Safety of Registered Products in South Africa

This study will inform international medical guidelines as to whether the Levonorgestrel intrauterine device (LNG IUD), a highly effective long-acting reversible contraceptive method, is safe and acceptable as compared to the copper intrauterine device (C-IUD) for HIV-positive women in Cape Town, South Africa. If the LNG IUD is found to be safe and acceptable, the introduction of this method to HIV positive women in developing countries could significantly reduce unplanned pregnancy and mother-to-child transmission of HIV, and confer non-contraceptive benefits to HIV-positive women in Sub-Saharan Africa.

Design: Single site, double-blind, randomized controlled trial

Population: HIV-positive South African women between the ages of 18 and 40 years

Study size: At least 166 women

Study intervention: Levonorgestrel intrauterine device (LNG IUD) or the copper T-380 intrauterine device (C-IUD)

Duration & Follow-up: Approximately 48 months in total. Recruitment will take approximately 24 months. After enrollment, each participant will be followed for 24 months.

Primary Objectives: To compare LNG IUD safety to the safety of the C-IUD with respect to genital HIV shedding, a surrogate for potential for HIV transmission, overall and in the presence and absence of antiretroviral therapy (ART).

Secondary Objectives: 1) To compare LNG IUD safety to the safety of the C-IUD with respect to HIV progression as measured by changes in plasma viral load (VL) at 6 months between the two pre-ART study arms. 2) To explore LNG IUD safety with respect to non-HIV related outcomes, including hemoglobin change, incidence of sexually-transmitted infections (STIs) and pelvic inflammatory disease (PID). 3) To measure LNG IUD acceptability through device continuation and other measures for the LNG IUD as compared to the C-IUD. 4) To compare three genital tract sampling methods to determine which provides optimal recovery of HIV RNA and immune mediators over a series of three visits.

Primary Endpoints: Change in detection and quantity of HIV ribonucleic acid (RNA) genital VL measures between study arms at baseline and 6 months, and over 24 months following IUD insertion.

Secondary Endpoints: 1) Measures of HIV disease progression, including CD4 change, time to ART initiation, and mean plasma VL change from baseline to 6 and through 24 months among pre-ART women. 2) Hemoglobin change and incidence of STIs and PID for all participants through 24 months. 3) IUD continuation and expulsion rates between study arms comparing different IUDs over a 24-month period and acceptability measures through quantitative and qualitative methods. 4) Comparison of female genital tract sampling methods for recovery of HIV RNA as measured by VL and immune mediators (e.g. cytokines).

Study Site: Gugulethu Community Health Centre (GCHC), Cape Town, South Africa
