- Primary Outcome Measures
Name Time Method Phase 1: Number of Participants With Any Treatment-emergent Adverse Event (TEAE) up to 285 days An adverse event (AE) was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related, that occurred after a participant provided informed consent. Abnormal laboratory values or test results occurring after informed consent constituted AEs only if they induced clinical signs or symptoms, were considered clinically meaningful, required therapy (e.g., hematologic abnormality that required transfusion), or required changes in the study drug(s). A TEAE was defined as any AE either reported for the first time or the worsening of a pre-existing event after the first dose of study drug and until 30 days after the last dose of study drug.
Phase 1: Number of Participants With Any Grade 3 or Higher TEAE up to 285 days An adverse event (AE) was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related, that occurred after a participant provided informed consent. Abnormal laboratory values or test results occurring after informed consent constituted AEs only if they induced clinical signs or symptoms, were considered clinically meaningful, required therapy (e.g., hematologic abnormality that required transfusion), or required changes in the study drug(s). A TEAE was defined as any AE either reported for the first time or the worsening of a pre-existing event after the first dose of study drug and until 30 days after the last dose of study drug. Grade 3: severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care activities of daily living. Grade 4: life-threatening consequences; urgent intervention indicated.
Phase 2: Objective Response Rate (ORR), Defined as the Percentage of Participants Achieving Either a Complete Response (CR) or a Partial Response (PR), Per the Modified Lugano Classification for Diffuse Large B-cell Lymphoma (DLBCL) up to 1538 days CR: (1) target nodes/nodal masses of lymph nodes/extralymphatic sites regressed to ≤1.5 centimeters (cm) in the longest dimension transverse diameter of lesion (LDi); (2) absence of non-measured lesions; (3) organ enlargement regressed to normal; (4) no new lesions; (5) normal bone marrow morphology; if indeterminate, immunohistochemistry negative. PR: (1) lymph nodes/extralymphatic sites: ≥50% decrease in the sum of the product of perpendicular diameters for multiple lesions of up to 6 target measurable nodes/extranodal sites; if lesion is too small to measure on computed tomography, assign 5 millimeters (mm) × 5 mm as default; if no longer visible, 0 mm × 0 mm. For node \>5 mm × 5 mm but smaller than normal, use actual measurement; (2) absent/regressed non-measured lesions, no increase; (3) organ enlargement; spleen regressed by \>50% in length beyond normal; (4) no new lesions.
Phase 1: Number of Participants With Any Dose-limiting Toxicity (DLT) up to Day 28 A DLT was defined as the occurrence of any protocol-defined toxicities occurring up to and including Study Day 28, except those with a clear alternative explanation (e.g., disease progression) or transient (≤72 hours) abnormal laboratory values without associated clinically significant signs or symptoms based on investigator determination. All DLTs were assessed by the investigator using Common Terminology Criteria for Adverse Events (CTCAE) v4.03 criteria. In order to be included in the tolerability review, subjects must have received the cohort-specific dose of INCB039110 and ibrutinib for at least 75% of the days during the 28-day surveillance period or have experienced a DLT.
