Study Drug Administration:
If participants are found to be eligible to take part in this study, they will receive pembrolizumab by vein over about 30 minutes on Day 1 (+/- 3 days) of each 21-day cycle.
They will also receive hormonal therapy that their doctor has chosen for their standard treatment. The study doctor will tell them which hormonal therapy they receive, its risks, and how often they will receive it.
Length of Study:
They may continue taking the study drug for up to 24 months, as long as the doctor thinks it is in their best interest. They will no longer be able to take the study drug if the disease gets worse, if intolerable side effects occur, or if they are unable to follow study directions.
Their participation on the study will be over after the follow-up visits (described below).
On Day 1 of each cycle:
- They will have a physical exam
- Blood (about 2 tablespoons) will be drawn for routine tests.
At Cycle 4 and then every 3 cycles after that (before Cycle 4, 7, 10, 13 and so on), they will have imaging scans, including an EKG and either an ECHO or MUGA scan, to check the status of the disease as part of their standard care. Also, blood (about 7 tablespoons) will be drawn for biomarker and immune system testing. This blood will also be drawn if the disease appears to get worse.
As soon as possible after they stop receiving the study drugs:
- They will have a physical exam.
- Blood (about 10 tablespoons) will be drawn for routine, biomarker, and immune system testing.
- They will have the same imaging scans they had at screening to check the status of the disease.
- If the doctor thinks it is needed, they will have an EKG and either an ECHO or MUGA scan.
About 1 month after the last dose of study drugs, they will be asked about their health and any side effects they may have had. They may be asked during a routine clinic visit or they may be called. If they are called, each call should last about 2 minutes.
If they stopped taking the study drugs for reasons other than the disease getting worse, they will be called about 24 months after their first dose of pembrolizumab to learn how they are doing. If they are called, this should last about 3 minutes.
