Study Summary

Background: Chronic lymphocytic leukemia (CLL) is a blood cancer. Recombinant human interleukin 15 (IL-15) is a manmade protein. Obinutuzumab is a protein made to deactivate cancer cells. Researchers want to see if treating people with CLL with both proteins improves their outcomes. Objectives: To find the safe dose of IL-15 with Obinutuzumab. To identify its effects, including on the immune system and cancer. Eligibility: Adults at least 18 years old who have certain CLL that standard therapy has failed Design: Participants will be screened with: * Medical history * Physical exam * Evaluation of ability to do daily activities * Blood, heart, and urine tests Participants may also be screened with: * A small amount of bone marrow removed by needle in the hipbone * Scans of the body and/or brain The study will be done in 28-day cycles for up to 6 cycles. Participants will get the study drugs through a catheter and pump. Cycle 1: Participants will be seen in the clinic during week 1. They will get: * IL-15 as a continuous intravenous infusion over 24 hours on days 1-5 and 3 dose levels will be evaluated: dose level 1; 0.5 mcg/kg/day; dose level 2: 1 mcg/kg/day and dose level 3: 2 mcg/kg/day. * Obinutuzumab as a 4-hour infusion in escalating doses during the course of the first cycle 100 mg on day 4, 900 mg on day 5, 1000 mg on day 11 and day 18. Cycles 2 through 6: Participants will come to the clinic days 1-5 and get IL-15 as in cycle 1 and Obinutuzumab 1000 mg on day 4 of each treatment cycle. During the study, participants: * Will repeat screening tests * Will get standard medicines for side effects * May give blood, saliva, and tumor samples for research After treatment, participants will have follow-up visits every 3 months for 1 year, then every 6 months for up to 5 years. After that, participants may be called or emailed.
