Brief description of study

This study aims to learn more about the use of Mirvetuximab soravtansine and Olaparib as a
maintenance therapy after completion of prior therapy for recurrent platinum sensitive ovarian,
peritoneal and fallopian tube cancer. Mirvetuximab soravtansine is an effective antibody drug
conjugate that targets folate receptor alpha. Olaparib is one of three drugs currently approved
by the U.S. Food and Drug Administration (FDA) in the setting of ovarian cancer.

Detailed description of study

If you join the study, you will receive a combination therapy of Mirvetuximab soravtansine and

Olaparib. Study treatment will be conducted until disease progression or other reason for discontinuation.

Cycles will be 21 days. You will be administered Mirvetuximab soravtansine on Day 1 and take

the study drug Olaparib on Day 1 through Day 21. You will continue to repeat this dosing

schedule until your study doctor tells you otherwise. At the beginning of each cycle, we will have

you come into clinic for the following procedures/assessments:

- We will ask you about medications you are taking, adverse events you are experiencing,

past medical procedures, and any ocular symptoms you are experiencing

- Serum pregnancy for women of childbearing potential/not underwent surgical

menopause.

- We will ask you about your Olaparib medication and dispense you a new cycle of

medication. The doctor may adjust your dose if necessary.

- We will administer you your Mirvetuximab soravtansine. The doctor may adjust your

dose if necessary.
