Change of Vaginal Maturation Index (VMI) from Day 1 to Day 43 [1] | ||||||||||||
End point description |
Full Analysis Set.
The VMI quantifies the relative proportion of the vaginal parabasal, intermediate, and superficial cells in the vaginal epithelium. The Vaginal Maturation Index is calculated as follows:
Vaginal Maturation Index = 1.0 x % superficial cells + 0.5 x % intermediate cells + 0.0 x % parabasal cells

Notes [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point. Justification: Since there was no comparison group, mean VMI between Day 1 and Day 43 was compared. A paired t-test (one-sided) with a significance level of p = 0.05 was conducted, showing a statistically significant improvement of the VMI |

The content of L-lactic acid was updated, taking into account the Ph. Eur. specification for content. According to Ph. Eur, the content of anhydrous L-lactic acid is 90% w/w (range between 88.0% - 92.0% (w/w). Therefore, 167 mg L-lactic acid equal to 150 mg anhydrous L-lactic acid. In combination with 50 mg sodium L-lactate solution, which equals to 40 mg anhydrous L-lactic acid, this results in a total of 190 mg of anhydrous L-lactic acid.
The primary packaging of the vaginal suppositories was changed from PVC/PVDC/PE blisters to Alu/PE blisters. |
