Background: The objectives of this clinical trial were to evaluate the safety, tolerance and acceptability of two gel formulations of the Invisible Condom (R): (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 Design: A randomized, doubled-blind, placebo-controlled study in healthy women from Yaounde, 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. Results: Retention 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. Conclusion: The Invisible Condom (R) 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. (C) 2009 Elsevier Inc. All rights reserved.
