Study Summary

This phase III trial studies how well letrozole with or without paclitaxel and carboplatin works in treating patients with stage II-IV low-grade serous carcinoma of the ovary, fallopian tube, or peritoneum. Letrozole is an enzyme inhibitor that lowers the amount of estrogen made by the body which in turn may stop the growth of tumor cells that need estrogen to grow. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving letrozole alone or in combination with paclitaxel and carboplatin works better in treating patients with low-grade serous carcinoma of the ovary, fallopian tube, or peritoneum compared to paclitaxel and carboplatin without letrozole.

Primary Outcome

The PFS comparison will be assessed at the second interim and final analyses using a logrank test stratified by country and residual disease status. Estimates for the letrozole/letrozole (L/L) vs paclitaxel/carboplatin/letrozole (CT/L) hazard ratio and its confidence interval will be obtained using a stratified Cox proportional hazards model. Potential confounding factors, including the stratification factors, performance status and self-declared racial designation will be considered in a final
