Brief Summary:
The primary objective of this study is to study the vaginal flora colonisation equivalence between the tablet and capsule dosage forms of a treatment with Lcr Regenerans® between D0 (V1) and Dend of treatment.

Condition or disease Intervention/treatment Phase
Candidiasis, Vulvovaginal Device: Lcr Regenerans® vaginal capsules Device: Lcr Regenerans® vaginal tablet Phase 1

Detailed Description:

The healthy vaginal microbiota is mainly colonised by strains of Lactobacillus which play an important role in defence against vaginal infections. The intravaginal use of probiotic strains stimulating the recolonisation of the endogenous vaginal microbiota and capable of inhibiting the growth of pathogens such as Candida albicans appears to be an interesting alternative to prevent recurrences of VVC. Recently, longitudinal studies have revealed that the vaginal microbiota is relatively stable and that the main cause of disturbance to the stability of the vaginal microbiota is over short menstruation periods. However, the use of antimicrobial agents induces severe disturbances with disappearance of certain endogenous species over several weeks. These results suggest that antimicrobial treatments severely affect the vaginal flora and that probiotics are therefore recommended to help re-establish a vaginal microbiota after this treatment.

For this, a sufficient direct local supply must be provided. The general data from studying the vaginal microbiota reveal that in the healthy woman, the concentration of Lactobacilli is greater than or equal to 107 CFU/ml of vaginal secretion. During capsule administration, all the Lactobacilli are immediately released into the vaginal cavity. The natural vaginal secretions, estimated to be an average of 0.51 ml/day, result in daily elimination of around 107 to 108 CFU and therefore generates very rapid elimination of this supply which requires daily administrations.

The objective of this clinical trial is to prove that the two dosage forms, capsule administered daily and tablet administered at a certain dosage, enable equivalent local provision of a concentration which is greater than or equal to 10e7 CFU (this concentration ensures the establishment of a sufficiently large bacterial population to enable efficacy of the product).

Therefore, the optimal dosage of the Lcr Regenerans® tablet to be administered and which will be equivalent to the daily administration of the Lcr Regenerans® capsule will be determined during this trial. To do this, 3 different dosages of the Lcr Regenerans® tablet, corresponding to or encompassing the time during which the tablet provides continuous release and presence of the strain in the in vitro model, will be compared to that of the Lcr Regenerans® capsule. For this reason, the frequencies of administration for the Lcr Regenerans® tablet will be 3, 4 or 5 days.
