Clinical Trial Summary

There is promising evidence that couple-based approaches within Malawi's Option B+ prevention of mother to child transmission program could address help address 1) poor male engagement in the HIV continuum of care, 2) low male adoption of biomedical HIV prevention approaches, 3) sub-optimal female engagement in the continuum of care, and 4) poor or uncertain infant outcomes. Our team has developed an intervention to address these challenges, and will conduct a randomized controlled trial (N=500 couples) to assess intervention effectiveness at one year. Women with recent HIV infections enrolled in this trial will be compared against a cohort of 350 HIV-uninfected women to explore predictors of HIV acquisition in pregnancy in Malawi.

Description:

In sub-Saharan Africa, engaging HIV-infected men in HIV care and treatment and engaging HIV-uninfected men in prevention has proven challenging. Along all steps of the HIV care-seeking cascade, men exhibit worse care-seeking behaviors. They are less likely to seek HIV testing and counseling (HTC), initiate combination antiretroviral therapy (cART), and be retained in cART care. Poor care-seeking has resulted in a lower prevalence of viral suppression and earlier mortality. Additionally, men rarely engage in the antenatal care-seeking of their female sexual partners, leading to worse maternal and infant outcomes. This low level of engagement has been noted in Malawi's Option B+ prevention of mother to child transmission (PMTCT) program, and has been a critical barrier to female Option B+ uptake and retention, and a missed opportunity for engaging men.

There is promising evidence that couple-based approaches within Malawi's Option B+ prevention of mother to child transmission program could address all of these challenges: poor male engagement in the HIV continuum of care, low male adoption of biomedical HIV prevention approaches, sub-optimal female engagement in the continuum of care, and poor or uncertain infant outcomes. Our team has designed a couples-based intervention to address these challenges, and will conduct a randomized controlled trial (N=500 couples) to assess intervention effectiveness at one year. Results from this study are expected to inform how best to address family outcomes in an Option B+ program.

This study has the following aims described below:

Aim 1: Determine whether the couple-based intervention increases new HIV-positive diagnoses among HIV-infected male sex partners, helps HIV-infected men engage and remain in care, and contributes to male viral suppression compared to individual standard of care. The investigators will compare the couple-based intervention to standard of care for increasing the proportion of men who are aware of being HIV-infected, the proportion of these men who initiate and remain in cART care, and the proportion of these men with viral suppression at one year.

Aim 2: Determine whether the couple-based intervention identifies HIV-discordant couples and decreases the likelihood of male exposure to HIV compared to individual standard of care. The investigators will compare the intervention to standard of care for increasing the number of men with non-HIV exposure from their female partner through consistent condom use, viral suppression, abstinence, or a combination of these methods over one year.

Aim 3: Determine whether the couple-based intervention improves female cART retention and viral suppression compared to individual standard of care. The investigators will compare the intervention to standard of care for female cART retention and viral suppression at one year.

Aim 4: Determine whether the couple-based intervention improves infant early infant diagnosis uptake compared to individual standard of care. Explore uptake of early infant diagnosis and rates of mother-to-child transmission and child survival in the two intervention arms.

Aim 5: Develop an in-depth understanding of HIV transmission dynamics in Lilongwe. Using the biomarkers and behavioral survey, we will seek to understand transmission timing, direction, and context in Lilongwe. We will compare women with recent HIV infection to a population of HIV-uninfected controls (n=350) to understand predictors of HIV acquisition in pregnancy in Malawi.

Intervention

Behavioral:
• Enhanced Couple HIV Testing and Counseling
Participants are provided study-specific partner referral cards and encouraged to bring male partners to antenatal care for a male engagement intervention. Those who do not present on their own are then traced. Couples will receive three enhanced couple counseling sessions that include: pre-test counseling, return of joint results, and post-test counseling. HIV-infected men will be able to initiate cART at the antenatal clinic and the couple will be offered condoms from the HTC counselor. Between sessions, couple members can pick up condoms and cART for one another.
