Acceptability of Praneem polyherbal vaginal tablet among HIV uninfected women & their male partners in Pune, India--Phase I study.

BACKGROUND & OBJECTIVE: The number of HIV infected women is steadily increasing worldwide and women controlled methods to prevent HIV are urgently needed. Vaginal microbicides are products for vaginal administration that can be used to prevent HIV infection and other sexually transmitted diseases (STDs). We conducted a Phase I safety and acceptability study of Praneem polyherbal tablet, a candidate microbicide, among HIV uninfected women in Pune, India. METHODS: Twenty eligible women were requested to use the product intravaginally once daily for 14 consecutive days between menses. Safety was assessed by clinical examination, laboratory monitoring and colposcopy. Acceptability was assessed after 14 days of product use through structured questionnaires, focus group discussions among participating women, and in-depth interviews with a subset of 5 randomly selected male partners. RESULTS: Praneem polyherbal tablet was found acceptable by the study participants with 90 per cent of the participants showing 80 per cent and more acceptability score. Discharge of the product residue was reported as a concern by 6 (30%) of participants. Nineteen (95%) female participants liked the smell and the same number reported that the product was easy to use and did not affect the usual sexual pleasure. However, men reported lack of sexual satisfaction. INTERPRETATION & CONCLUSION: Product characteristics received good acceptability score in women. However, studies of long-term safety and acceptability among at-risk population would provide more detailed information about its long term acceptability.

Acceptability and adherence: findings from a Phase II study of a candidate vaginal microbicide, 'Praneem polyherbal tablet', in Pune, India.

Acceptability and adherence in clinical trials of microbicides may possibly predict their acceptance by the community. In this study, we investigated the acceptability and adherence of Praneem polyherbal tablet, a candidate microbicide, among 100 HIV-uninfected participants of a Phase II randomised, double-blind, placebo-controlled trial in Pune, India, conducted between June 2004 and February 2006 involving 6 months of coitally-dependent product use. The relationship between five acceptability domains and adherence to product use during the study period was explored. Acceptability and adherence were assessed among 95 study participants completing all study follow-ups. One hundred percent adherence (product use during each sex act for the study period) was reported by 67 participants (70.5%). The majority of participants reported acceptability towards all product characteristics. Product odour was reported to be a concern both in the placebo and Praneem arms. Participants from the Praneem arm [adjusted odds ratio (AOR)=3.8; 95% CI 1.4-10.8] and participants reporting lower acceptability for experience of product use during the sex act (AOR=4.2; 95% CI 1.0-17.3) were more likely to have partial adherence. In conclusion, the study product was acceptable to the majority of participants. However, barriers to adherence attributable to undesirable sexual experiences need to be addressed.
