Title
Phase I/II Study of Nivolumab in Combination with Ruxolitinib in Relapsed or Refractory Classical Hodgkin Lymphoma

Description
Phase I Study of Nivolumab + Ruxolitinib in Relapsed/Refractory Classical Hodgkins Lymphoma

Objective
This study is being done to determine the maximum tolerated dose (highest dose) of ruxolitinib that can be given safely in combination with nivolumab. This study will also:

Measure the percentage of tumor (lymphoma) that shrank after receiving ruxolitinib in combination with nivolumab

Measure the length of time the lymphoma is inactive and

Study how safe the combination is to administer to participants.

Treatment If you are eligible and agree to participate, you will receive the study drugs as described below:

Nivolumab will be given once every four weeks. Nivolumab will be given through a vein (IV), which is also called an infusion

Ruxolitinib is a pill that you will take two times per day, every day

During the first cycle, you will take ruxolitinib for 1 week before you receive the first nivolumab infusion

The study drugs will be given in units of time called cycles. One cycle equals 28 days (4 weeks). The first 2 participants treated in the study will receive ruxolitinib at dose level 1 (10 mg twice a day). If participants do well at this dose for 35 days, then the next set of 2 will be enrolled at dose level 2 (15 mg twice daily). If they do well for 35 days then dose level 3(20 mg twice a day). If at any time the side effects experienced by patients are too severe, the dose level will be decreased

Key Eligibility
