NCT03010358 · STUDY IN CONTEXT

Entospletinib and Obinutuzumab in Treating Patients With Relapsed Chronic Lymphocytic Leukemia, Small Lymphocytic Lymphoma, or Non-Hodgkin Lymphoma

Draft scope assessment: narrower. Linked by condition-string match at the cancer-entity level. The study's eligibility - stage, biomarker, treatment line and prior therapy - has not been reconciled against this page's definition, so its population is narrower than this page in ways not yet recorded. The condition was transformed or resolved through the terminology hierarchy to reach this cancer type, so the link itself is a candidate a reviewer must confirm. Found by searching ClinicalTrials.gov for this cancer type, restricted to studies that have posted results to the registry. No FDA notice, FDA label or NCI summary held by this site cites this study. Because the search asked for posted results, studies without posted results were never looked for, so their absence from this page means nothing.

primary · POSTED

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.

Will be assessed by National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.03. Will be summarized for the safety population separately for phase 1 and phase 2 portions by dose level. All adverse events (AEs) will be coded by system organ class, Medical Dictionary for Regulatory Activities (MedDRA) preferred term, and severity grade using NCI CTCAE (version 4.03).

    The Outcome Measure was assessed in aggregate, combining participants from both phases of the study, as per the planned protocol. Phase 1, Dose 1 received entospletinib at Dose Level 1: 400 mg daily (200 mg twice daily) in combination with obinutuzumab during Dose Escalation phase of study. Phase 1, Dose 2 received entospletinib at Dose Level 2: 800 mg daily (400 mg twice daily) in combination with obinutuzumab during Dose Escalation phase of study. Phase 2, MTD: Received entospletinib at Maximum Tolerated Dose (MTD) in combination with obinutuzumab during Dose Expansion phase of study. The MTD was determined to be 800 mg daily (400 mg twice daily).
