BackgroundThe objectives of this clinical trial were to evaluate the safety, tolerance and acceptability of two gel formulations of the Invisible Condom®: (i) the polymer alone and (ii) the polymer-containing sodium lauryl sulfate (SLS) compared to placebo when applied intravaginally with our unique applicator in sexually abstinent and active woman volunteers.Study DesignA randomized, doubled-blind, placebo-controlled study in healthy women from Yaoundé, Cameroon. Two hundred sixty women were randomized into three gel arms: (a) gel alone, (b) gel plus SLS and (c) placebo gel. Thirty-seven sexually abstinent women applied gel intravaginally once a day for 14 days, while 75, 74 and 74 sexually active women applied gel intravaginally once, twice or three times daily for 14 days, respectively.ResultsRetention rate was high at 85% and 221 women applied the two products and the placebo for a total of 6005 times. Nugent score, H2O2-producing lactobacilli and vaginal pH were stable throughout the study and were not affected by the study products. Colposcopy showed neither genital ulceration nor mucosal lesions. No study product-related serious adverse events were reported. The majority of reported adverse events were mild or moderate and largely similar in all 3 arms. Satisfaction questionnaire showed that the gel formulations and applicator were generally comfortable and acceptable.ConclusionThe Invisible Condom® formulations and applicator were found to be comfortable, well tolerated and acceptable when applied intravaginally once, twice or thrice daily for 14 days. Thus, expanded safety evaluation is warranted.
