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.

The effects of rhIL-15 and Obinutuzumab on the developing human fetus are unknown. Additionally, CD20-depleting agents are known to produce opportunistic infections, causing fetal B-cell depletion in animal studies, and may be teratogenic. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. NOTE: WOCBP is defined as any female who has experienced menarche and who has not undergone successful surgical sterilization or who is not postmenopausal. WOCBP must have a negative pregnancy test (Human chorionic gonadotropin (HCG) blood or urine) during screening. - Ability of patient to understand and the willingness to sign a written informed consent document.

Secondary | Duration of Response (DOR) | DOR is measured from the time measurement criteria are met for complete response (CR), complete response with incomplete marrow recovery (CRi), or partial response (PR) whichever is recorded first until the first date that recurrent of progressive disease is objectively documented, death, or in the absence of progressive disease (PD), date of last assessment. Response was assessed by the International Workshop on Chronic Lymphocytic Leukemia (iwCLL) 2018 guidelines. Complete response (CR) is disease related constitutional symptoms resolved; partial response (PR) is two criteria from Group A (e.g. lymphadenopathy or liver and/or spleen size) if abnormal at baseline plus one of the criteria from Group B (e.g. platelet count) must be met; complete response with incomplete marrow recovery (CRi) is CR with incomplete hematopoietic recovery; stable disease (SD) is defined as not achieving CR or PR, and PD is development of transformation to a more aggressive histology. | time measurement criteria are met for CR, CRi, or PR whichever is recorded first until the first date that recurrent of progressive disease is objectively documented or death, approximately 27 months | |
Secondary | Overall Response Rate | Overall response is defined as the best response recorded from the start of the treatment until disease progression/recurrence. OS was estimated using the Kaplan-Meier curves and a 95% confidence interval. Response was assessed by the International Workshop on Chronic Lymphocytic Leukemia (iwCLL) 2018 guidelines. Complete response (CR) is disease related constitutional symptoms resolved; Partial response (PR) is two criteria from Group A (e.g. lymphadenopathy or liver and/or spleen size) if abnormal at baseline plus one of the criteria from Group B (e.g. platelet count) must be met, requires the absence of growth factor or transfusion support; Complete response with incomplete marrow recovery (CRi) is CR with incomplete hematopoietic recovery; Stable disease (SD) is defined as not achieving CR or PR, but not fulfilling the criteria for progressive disease (PD); and PD is one criteria from Group A or B are met or development of transformation to a more aggressive histology. | 6 cycles (each cycle is 28 days or 4 weeks) | |
Secondary | Event-free Survival (EFS) | EFS is defined as the duration of time from the date of study enrollment until time of disease lapse, disease progression, alternative therapy for lymphoma given, or death, whichever comes first. EFS was estimated using the Kaplan-Meier curves and a 95% confidence interval. Progression was assessed by the International Workshop on Chronic Lymphocytic Leukemia (iwCLL) 2018 guidelines and is defined as one criterion from Group A (e.g., lymphadenopathy or liver and/or spleen size) or B (e.g., platelet count) are met or development of transformation to a more aggressive histology. | Approximately 8 months | |
Secondary | Overall Survival (OS) | OS is defined as the date of on-study to the date of death from any cause or last follow up. | Approximately 27 months | |
Secondary | Progression-free Survival (PFS) | PFS is defined as the duration of time measurement criteria are met for complete response (CR), complete response with incomplete marrow recovery (CRi), and partial response (PR), whichever is recorded first. PFS was estimated using the Kaplan-Meier curves and a 95% confidence interval. Response was assessed by the International Workshop on Chronic Lymphocytic Leukemia (iwCLL) 2018 guidelines. CR is disease related constitutional symptoms resolved; PR is two criteria from Group A (e.g. lymphadenopathy or liver and/or spleen size) if abnormal at baseline plus one of the criteria from Group B (e.g. platelet count) must be met, requires the absence of growth factor or transfusion support; CRi is CR with incomplete hematopoietic recovery; and progressive disease is one criteria from Group A or B are met or development of transformation to a more aggressive histology. | Approximately 8 months |
