- Lead Sponsor
- Incyte Corporation
- Brief Summary
This is a Phase 2, open-label, 2-cohort study designed to evaluate the efficacy and safety of 2 parsaclisib treatment regimens in participants with relapsed or refractory mantle cell lymphoma (MCL) previously treated either with or without a Bruton's tyrosine kinase (BTK) inhibitor.

Group Intervention Description Cohort 1: Treatment B (Exposed to Ibrutinib) Parsaclisib Participants received parsaclisib 20 mg tablets, orally, QD for 8 weeks followed by 2.5 mg QD for up to 116 weeks. Participants who were exposed to ibrutinib before enrollment were included in this group. Cohort 1: Treatment A (Exposed to Ibrutinib) Parsaclisib Participants received parsaclisib 20 mg tablets, orally, once daily (QD) for 8 weeks followed by 20 mg once weekly (QW) for up to 52 weeks. Participants who were exposed to ibrutinib before enrollment were included in this group. Cohort 2: Treatment B (Bruton's Tyrosine Kinase Inhibitor Naïve) Parsaclisib Participants received parsaclisib 20 mg tablets, orally, QD for 8 weeks followed by 2.5 mg QD for up to approximately 136 weeks. Participants who had not received a BTK inhibitor previously were included in this group. Cohort 2: Treatment A (Bruton's Tyrosine Kinase Inhibitor Naïve) Parsaclisib Participants received parsaclisib 20 mg tablets, orally, QD for 8 weeks followed by 20 mg QW for up to approximately 145 weeks. Participants who had not received a BTK inhibitor previously were included in this group.
- Primary Outcome Measures
Name Time Method Objective Response Rate (ORR) Up to 1016 days 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.
- Secondary Outcome Measures
Name Time Method Overall Survival (OS) Up to 2017 days OS is defined as the time from the date of the first dose of study treatment until death from any cause.
Duration of Response (DOR) Up to 1016 days 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.
Complete Response Rate (CRR) Up to 1016 days CRR is defined as the percentage of participants with a CR as defined by 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.
Progression-Free Survival (PFS) Up to 1016 days PFS is 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.
Best Percent Change From Baseline in Target Lesion Size Up to 1016 days 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 nonmissing 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) From first dose of study drug up to 2045 days An adverse event (AE) is 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. A TEAE is any AE either reported for the first time or worsening of a pre-existing event after first dose of study drug and within 30 days of the last administration of study drug regardless of starting new anti-lymphoma therapy. A 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.
