Entospletinib and Obinutuzumab in Treating Patients With Relapsed Chronic Lymphocytic Leukemia, Small Lymphocytic Lymphoma, or Non-Hodgkin Lymphoma
A Phase I/II Study of Syk Inhibitor Entospletinib (GS-9973) in Combination With Obinutuzumab in Patients With Relapsed/Refractory Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma (CLL/SLL) and B-Cell Malignancies

Brief Summary
This phase I/II trial studies the side effect and best dose of entospletinib when giving together with obinutuzumab and to see how well they work in treating patients with chronic lymphocytic leukemia, small lymphocytic lymphoma, or non-Hodgkin lymphoma that has come back. Entospletinib may stop the growth of cancer cells by blocking some of the enzymes need for cell growth. Monoclonal antibodies, such as obinutuzumab, may interfere with the ability of cancer cells to grow and spread. Giving entospletinib and obinutuzumab together may work better in treating patients with chronic lymphocytic leukemia, small lymphocytic lymphoma, or non-Hodgkin lymphoma.

Outcome Measures
Primary Outcomes (2)
Maximum Tolerated Dose (MTD) of Entospletinib in Combination With Obinutuzumab
The dose of obinutuzumab remains fixed in standard doses while the dose of entospletinib will be escalated. The starting dose of entospletinib will be 200 mg (twice-daily) and escalated to the second dose level 400 mg (twice-daily). MTD is the dose associated with a total of 6 patients treated with less than 2 dose limiting toxicities (DLT), or a total of 3 patients treated with less than 1 DLT. DLT is defined as 1) grade 3 or higher non-hematological toxicity (except grade 3 nausea, vomiting or diarrhea that was reversible within 72 hours with supportive care; grade 3 infusion-related toxicity; asymptomatic grade 3-4 laboratory abnormalities that are reversible to grade 2 or less within 72 hours; grade 3 tumor lysis syndrome or hyponatremia); 2) grade 4 neutropenia lasting \>7 days or febrile neutropenia; or 3) grade 4 thrombocytopenia/anemia or grade 3 thrombocytopenia with bleeding. The dosage follows the 3+3 traditional escalation rules.
Up to 28 days
Complete Response (CR) Defined as the Percentage of Subjects Who Achieve CR
Response for CLL/SLL measured using Modified International Workshop on Chronic Lymphocytic Leukemia updating the National Cancer Institute-Working Group 1996 (IWCLL) guidelines. Response for hairy cell leukemia was measured using Consensus resolution: proposed criteria published in Leukemia 1987.
Up to 45 months
Secondary Outcomes (3)
Objective Response Rate (ORR)
Up to 45 months
Event Free Survival (EFS)
The interval between the date of first study treatment and the date of objective signs of disease recurrence, subsequent anti leukemic therapy, or death, whichever is first reported, assessed up to 45 months.
Number of Participants Who Experienced Adverse Events
Up to 45 months
Other Outcomes (3)
Peripheral Blood B-cell Depletion and Recovery
Up to 45 months
Pharmacodynamics Parameters of NFkappaB Activation and Expression of Anti-apoptotic Proteins in Chronic Lymphocytic Leukemia (CLL) Cells
Up to 45 months
Biomarkers (Chromosomal Abnormalities, IGHV Mutational Status, p53 Mutational Status)
Up to 45 months
Study Arms (1)
Treatment (entospletinib, obinutuzumab)
EXPERIMENTALPatients receive entospletinib PO either QD or BID on days -7 to -1 (run-in phase) depending on the assigned dose level. Patients also receive obinutuzumab IV on days 1, 2, 8, and 15 of the first cycle, and on day 1 of subsequent cycles. Treatment with obinutuzumab repeats every 28 days for up to 6 cycles and daily treatment with entospletinib continues every 28 days for up to 12 cycles in the absence of disease progression or unexpected toxicity.

Eligibility Criteria
You may qualify if:
- Phase I portion of the study: Histologically or flow cytometry confirmed diagnosis of B-CLL/SLL according to National Cancer Institute (NCI)-Working Group (WG) 1996 guidelines
- Phase I portion of the study: The following types of NHL as documented by medical records and with histology based on criteria established by the World Health Organization (WHO):
- Mantle cell lymphoma (MCL)
- Follicular lymphoma (FL) - grades 1-3a
- Lymphoplasmacytic lymphoma (LPL)
- Marginal zone lymphoma (MZL)
- CLL in Richter's transformation
- B-cell prolymphocytic leukemia
- Phase I portion of the study: Patients with histologically confirmed classical hairy cell leukemia (HCL)
- Phase II portion of the study - histologically or flow cytometry confirmed diagnosis of BCLL/SLL according to NCI-WG 1996 guidelines; patients who lack CD23 expression on their leukemia cells should be examined for (and found NOT to have) either t(11;14) or cyclin D1 overexpression, to rule out mantle cell lymphoma
- Patients underwent \>= 1 prior chemotherapy-based or immunotherapy-based regimen or targeted therapy (e.g., inhibitors of BTK, PI3K etc.) administered for \>= 2 cycles, and have had either documented disease progression or no response (stable disease) to the most recent treatment regimen
- Patients with CLL/SLL must demonstrate active disease meeting at least 1 of the International Workshop on Chronic Lymphocytic Leukemia (IWCLL) 2008 criteria for requiring treatment:

- Unintentional weight loss \> 10% within the previous 6 months prior to screening
- Extreme fatigue (unable to work or perform usual activities)
- +16 more criteria
You may not qualify if:
- Prior therapeutic intervention with any of the following:
- Therapeutic anticancer antibodies within 4 weeks (rituximab), except within 6 months for obinutuzumab or a similar investigational type II monoclonal antibody;
- Radio- or toxin-immunoconjugates within 10 weeks;
- Inhibitors of BTK (ibrutinib), PI-3K (idelalisib), BH3-mimetic venetoclax, lenalidomide and other "targeted" therapy (including but not limited to investigational BTK and PI-3K inhibitors, etc.) - within 6 half-lives (i.e., 36 hours for ibrutinib)
- All other chemotherapy, radiation therapy within 3 weeks prior to initiation of therapy
- SYK inhibitors at any time
- Inadequate recovery from adverse events related to prior therapy to grade =\< 1 (excluding grade 2 alopecia and neuropathy)
- Chronic use of corticosteroids in excess of prednisone 30 mg/day or its equivalent
- Stem cell transplant recipients must have no evidence of and not receive treatment for graft-versus-host disease
- Concomitant use or use in the prior two weeks of moderate or strong CYP3A and CYP2C9 inducers or strong CYP2C9 inhibitors, including nutraceutical preparations, e.g., grapefruit juice and St John's wort
- History prior malignancy except:
- Malignancy treated with curative intent and no known active disease present for \>= 2 years prior to initiation of therapy on current study
- Adequately treated non-melanoma skin cancer or lentigo maligna (melanoma in situ) without evidence of disease
- Adequately treated in situ carcinomas (e.g., cervical, esophageal, etc.) without evidence of disease
- Asymptomatic prostate cancer managed with "watch and wait" strategy
