Screening details |
A total of 1535 patients were screened and 338 patient were randomized. However, 72 patients were not included in the modified intention to treat (mITT) analysis. This resulted in 94 CLLA, 88 CLPL, and 84 PLPL patients included in the primary mITT analysis. | ||||||||||||

Oral Clindamycin 300 mg 2 times per day for 7 days followed by LACTIN-V (Osel, Inc.) until completion of the clinical pregnancy scan at week 7-9. LACTIN-V (2 x 109 CFU/dose, 200 mg) regimen is once daily from the clindamycin stop for 7 consecutive days. If there are embryos to transfer (90%), then LACTIN-V treatment is continued twice weekly until clinical pregnancy scan, however with a maximum of 21 applicators per patient. If the patient has no embryos to transfer or is confirmed not pregnant (negative hCG test), then LACTIN-V treatment can be stopped after at least 7 days Lactin-V administration, but patients are allowed to use all 21 applicators | ||||||||||||

Notes [1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same. Justification: 338 patients were randomized however, 72 patients were not included in the modified intention to treat (mITT) analysis. This resulted in a total of 266 patients. |

Statistical analysis description |
For each treatment group CLLA, CLPL and PLPL the estimated proportions, risk ratios (RR) and their confidence intervals were calculated using uni- and multivariate logistic regression analyses by generalized linear models with log-link function. The significance level for the final analysis was set at 4.9% (95.1% confidence intervals) due to the preplanned interim analysis where an alpha of 0.1% was used.
