Objectives:

Primary:

Safety and tolerability of therapy with daratumumab in a cohort of patients with metastatic renal cell carcinoma and a cohort of patients with muscle invasive bladder cancer.

Secondary:

1A. To assess the proportion of patients who achieve pathological CR with daratumumab in patients with muscle invasive bladder cancer.

1B. To assess the objective response rate (ORR) to daratumumab in patients with metastatic renal cell carcinoma.

2. To assess the progression free survival for patients with metastatic renal cell carcinoma receiving Daratumumab.

Detailed Description:

Bladder Cancer Cohort:

Study Drug Administration:

If you are eligible and agree to take part in this study, you will receive daratumumab by vein 1 time each week for 4 weeks before your cystectomy. During Week 1, your dose of daratumumab will be given over 8 hours. After that, each dose will be given over about 4 hours.

In this study, the following will be done to lower the chance of a daratumumab infusion related reaction:

You will get drugs, including steroids, acetaminophen, and/or antihistamine before the infusion. If you are considered high risk, you may also get drugs, including inhaled steroids, after the infusion.

The infusion may be slowed down or stopped if you have a reaction. You may stay overnight in the hospital after the infusion so the study staff can check your health.

You may ask the study staff for more information about the types of medications you will receive to lower your chance of an infusion-related reaction, including how they are administered and their risks.

Length of Study:

You may receive up to 4 doses of daratumumab before your surgery. You will no longer be able to take the study drug if the disease gets worse, if intolerable side effects occur, or if you are unable to follow study directions.

Your participation on the study will be over after the follow-up visit (described below).

Study Visits:

During Weeks 1-4:

You will have a physical exam. Blood (about 2 tablespoons) will be drawn for routine and blood type testing. Daratumumab will interfere with blood type testing which is needed before blood transfusions can be given. For this reason, a test to find out your blood type will be performed before you receive daratumumab. You should carry the blood type card with you while you are on this study.

During Weeks 6-8 (the week of your surgery):

You will have a physical exam. Blood (about 2 tablespoons) will be drawn for routine tests and part of this sample will also be used for blood type testing.

You will have surgery to remove your bladder. You will sign a separate consent form explaining the procedure and its risks in more detail.

End-of-Study Visit:

During Weeks 12-14, blood (about 2 tablespoons) will be drawn for routine tests.

Follow-Up Visit:

During Week 18, blood (about 2 tablespoons) will be drawn for routine tests and you will be asked about any side effects you are having.

Renal Cancer Cohort:

Study Drug Administration:

If you are eligible and agree to take part in this study, you will receive daratumumab by vein 1 time each week for 8 weeks before your nephrectomy, metastasectomy, or biopsy. During Week 1, your dose of daratumumab will be given over 8 hours. After that, each dose will be given over about 4 hours.

In this study, the following will be done to lower the chance of a daratumumab infusion related reaction:

You will get drugs, including steroids, acetaminophen, and/or antihistamine before the infusion. If you are considered high risk, you may also get drugs, including inhaled steroids, after the infusion.

The infusion may be slowed down or stopped if you have a reaction. You may stay overnight in the hospital after the infusion so the study staff can check your health.

You may ask the study staff for more information about the types of medications you will receive to lower your chance of an infusion-related reaction, including how they are administered and their risks.

Length of Study:

You may receive up to 8 doses of daratumumab prior to your surgery or biopsy. You may receive additional doses of daratumumab after the surgery/biopsy for up to one year after your first dose. You will no longer be able to take the study drug if the disease gets worse, if intolerable side effects occur, or if you are unable to follow study directions.

Your participation on the study will be over after the follow-up visit (described below).

Study Visits:

During Weeks 1-8:

You will have a physical exam each week before you receive daratumumab. Blood (about 2 tablespoons) will be drawn for routine and blood type testing. Daratumumab treatment will interfere with blood type testing which is needed before blood transfusions can be given. For this reason, a test to find out your blood type will be performed before you receive daratumumab. You should carry the blood type card with you while you are on this study.

During Weeks 10-12 (the week of your surgery/tissue collection):

You will have a physical exam. Blood (about 2 tablespoons) will be drawn for routine tests, part of this sample will also be used for blood type testing.

You will have surgery to remove your kidney, a kidney cancer lesion, or repeat biopsy. You will sign a separate consent form explaining the procedure and its risks in more detail.

During Weeks 14-30:

You will have a physical exam and return every 2 weeks to receive daratumumab. Blood (about 2 tablespoons) will be drawn for routine and blood type testing.

During Weeks 30-52:

You will have a physical exam and return every month to receive daratumumab. Blood (about 2 tablespoons) will be drawn for routine and blood type testing.

End-of-Study Visit:

During Week 52, blood (about 2 tablespoons) will be drawn for routine tests.

Follow-Up Visit:

During Week 65, blood (about 2 tablespoons) will be drawn for routine tests and you will be asked about any side effects you are having.
