- Objective Response Rate With Parsaclisib Based on Lugano Classification Response Criteria [ Time Frame: Up to approximately 148 weeks ]ORR=percentage of participants with complete response(CR) or partial response(PR) per revised response criteria for lymphomas,determined by independent review committee(IRC).Criteria for CR:1.Target nodes/nodal masses of lymph nodes,extralymphatic sites regressed to≤1.5cm in longest dimension transverse diameter of lesion(LDi);2.Absence of non-measured lesion;3.Organ enlargement regressed to normal;4.No new lesions;5.Normal bone marrow morphology;if indeterminate,immunohistochemistry negative.Criteria for PR:1.Lymph nodes,extralymphatic sites- ≥50%decrease in sum of product of perpendicular diameters for multiple lesions(SPD)of up to 6 target measurable nodes,extranodal sites;if lesion is too small to measure on computed tomography(CT),assign5mm×5mm as default;if no longer visible,0×0mm.Node>5mm×5mm 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.
- Complete Response Rate With Parsaclisib Based on Lugano Classification Response Criteria [ Time Frame: Up to approximately 148 weeks ]CRR was defined as the percentage of participants with a CR as defined by revised response criteria for lymphomas as determined by an IRC. The criteria for CR included: 1. Target nodes/nodal masses of lymph nodes and extralymphatic sites must regress to ≤ 1.5 cm in LDi; 2. Absence of non-measured lesion; 3. Organ enlargement regressed to normal; 4. No new lesions; 5. Bone marrow must be normal by morphology; if indeterminate, immunohistochemistry negative.
- Duration of Response (DOR) [ Time Frame: Up to approximately 148 weeks ]DOR=time from first documented evidence of CR or PR until disease progression or death from any cause among participants who achieve an objective response as determined by IRC. Criteria for CR: 1.Target nodes/nodal masses of lymph nodes and extralymphatic sites must regress to ≤ 1.5 cm in LDi; 2. Absence of non-measured lesion; 3.Organ enlargement regressed to normal; 4.No new lesions; 5.Bone marrow must be normal by morphology; if indeterminate, immunohistochemistry negative. The criteria for PR included: 1.Lymph nodes and extralymphatic sites- a. ≥50% decrease in SPD of up to 6 target measurable nodes and extranodal sites; b. when a lesion is too small to measure on CT, assign 5 mm×5 mm as the default; c.when no longer visible, 0×0 mm. For a node >5 mm×5 mm but smaller than normal, use actual measurement. 2.Non-measured lesions- Absent/regressed, but no increase. 3. Organ enlargement-Spleen must have regressed by >50% in length beyond normal. 4.No new lesions.
- Progression-free Survival (PFS) With Parsaclisib [ Time Frame: Up to approximately 148 weeks ]PFS was defined as the time from the date of the first dose of study treatment until the earliest date of disease progression, as determined by radiographic disease assessment provided by an IRC, or death from any cause.
- Overall Survival (OS) With Parsaclisib [ Time Frame: Up to approximately 148 weeks ]OS was defined as the time from the date of the first dose of study treatment until death from any cause.
- Best Percent Change From Baseline in Target Lesion Size [ Time Frame: Up to approximately 148 weeks ]Target lesion size is measured by the sum of the product of diameters of all target lesion sizes and is determined by the IRC. The best percent change from Baseline is defined as the largest decrease, or smallest increase (if no decrease available), from Baseline in target lesion sizes on/before new (next-line) anti-lymphoma therapy during the study. Baseline is the last non-missing measurement obtained before the first administration of study drug. A negative percent change from Baseline indicates improvement.
- Percentage of Participants With Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) [ Time Frame: From first dose of study drug up to approximately 148 weeks ]An adverse event (AE) is defined as any untoward medical occurrence associated with use of a drug in humans, whether or not considered drug related, that occurs after a participant provides informed consent. TEAE is any AE either reported for first time or worsening of a pre-existing event after first dose of study drug and within 30 days of last administration of study drug regardless of starting new anti-lymphoma therapy. SAE is any untoward medical occurrence that results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, leads to a congenital anomaly/birth defect or is considered to be an important medical event that may not result in death, be immediately life-threatening, or require hospitalization but may be considered serious when, based on appropriate medical judgment, the event may jeopardize the participant or may require medical or surgical intervention.
