Randomized Cross-Over Study of Self-Insertion of Two Placebo Vaginal Film Formulations

This is a double-blinded crossover study to evaluate whether ammonio methacrylate copolymer dispersion type B (Eudragit®) content impacts the ability to self-insert placebo vaginal films. Eudragit® is a commonly used pharmaceutical excipient, present in several FDA approved products. This hydrophobic excipient is used in vaginal film formulations to increase disintegration time and impart extended drug release property. The presence of Eudragit and its concentration level affects film disintegration and spreadability in the vaginal environment, and are likely to affect tactile properties. Consequently, these attributes may impact ease of film administration, acceptability, and user preferences for specific film type. Thirty pre-menopausal women, 18 - 45 years of age, will self-insert one high and and one low Eudragit® content film. High and low Eudragit films correspond to 12.8% and 6.4% of Eudragit® added during the formulation blending stage. The insertion order will be randomized in a 1:1 ratio. Within 10 minutes of the insertion, clinical staff will perform a speculum exam to assess the location of the film and remove the residual film. After inserting each film, participants will complete a survey reporting their perceptions and experience. The primary endpoint is successful insertion defined as all of the film inside the vagina upon visual assessment by a study clinician. Secondary outcomes include preference for the low level or high level Eudragit® formulation film with respect to insertion and participants' description of identified challenges.
