Clinical Trial Summary

This is a Phase 3, double-blind, randomized, placebo-controlled, multicenter study of parsaclisib plus investigator's choice of either rituximab or obinutuzumab versus placebo plus investigator's choice of rituximab or obinutuzumab for the treatment of participants with R/R FL or MZL. The Participants will be stratified in a 1:1 randomization ratio by investigator's choice of rituximab or obinutuzumab prior to randomization, time since last antilymphoma therapy (≤ 2, > 2 years), and disease histology (MZL or FL) .

Recruitment information / eligibility

• Status: Withdrawn
• Enrollment: 0
• Est. completion date: August 25, 2032
• Est. primary completion date: December 20, 2028

• Gender: All
• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

• Male and female participants aged 18 years or older (Japan, aged 20 years or older).

• Histologically confirmed Grade 1, 2, or 3a FL or nodal MZL, splenic MZL, or extra nodal MZL

• Prior systemic treatment with at least 1 anti-CD20 mAb (either as monotherapy or in combination as chemoimmunotherapy)

• Documented disease that has relapsed or progressed or was refractory after the most recent prior systemic therapy. Note: Participants must not be refractory to anti-CD20 mAb

• Radiographically (CT, MRI) measurable lymphadenopathy per the Lugano criteria for response assessment (Cheson et al 2014).

• ECOG PS of 0 to 2

• Adequate organ functions including hematopoiesis, liver, and kidney

• Willingness to avoid pregnancy or fathering children

Exclusion Criteria:

• Women who are pregnant or breastfeeding.

• Known histological transformation from indolent NHL to an aggressive NHL (eg, diffuse large B-cell lymphoma).

• Presence of CNS lymphoma (either primary or secondary) or leptomeningeal disease.

• Prior treatment with PI3K inhibitors.

• Inadequate washout of immunosuppressive therapy, anticancer medications and investigational drugs.

• Significant concurrent, uncontrolled medical condition, including, but not limited to, renal, hepatic, hematological, GI, endocrine, pulmonary, neurological, cerebral, cardiac, infectious, or psychiatric disease.

• Known HIV infection.

• HBV or HCV infection: Participants positive for HBsAg or anti-HBc will be eligible if they are negative for HBV-DNA; these participants must receive prophylactic antiviral therapy. Participants positive for HCV antibody will be eligible if they are negative for HCV-RNA.

• History of other malignancy within 2 years of study entry.

• Any condition that would, in the investigator's judgment, interfere with full participation in the study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Progression Free Survival (PFS) in R/R FL and MZL participants	Defined as the time from the date of randomization until the first documented disease progression as determined by IRC based on the Lugano criteria for response assessment (Cheson et al 2014) or death from any cause, whichever occurs first.	62 months
Secondary	Progression Free Survival (PFS) in R/R FL participants	Defined as the time from the date of randomization until the first documented disease progression as determined by IRC based on the Lugano criteria for response assessment (Cheson et al 2014) or death from any cause, whichever occurs first.	62 months
Secondary	Overall Response Rate (ORR)	Defined as the proportion of participants with a CR or PR as determined by IRC based on the Lugano criteria for response assessment (Cheson et al 2014).	62 months
Secondary	Overall Survival (OS)	Defined as the time from the date of randomization until death from any cause.	10 years
Secondary	Progression Free Survival (PFS) in R/R MZL participants	Defined as the time from the date of randomization until the first documented disease progression as determined by IRC based on the Lugano criteria for response assessment (Cheson et al 2014) or death from any cause, whichever occurs first.	62 months
Secondary	Complete Response Rate (CRR)	Defined as the proportion of participants with a CR as determined by IRC based on the Lugano criteria for response assessment (Cheson et al 2014).	62 months
Secondary	Duration of Response (DOR)	Defined as the time from the date of first documented evidence of CR or PR until the first documented disease progression or death from any cause, whichever occurs first, among participants who achieve an objective response as determined by IRC based on the Lugano criteria for response assessment (Cheson et al 2014).	62 months
Secondary	Disease Control Rate (DCR)	Defined as the proportion of participants who achieve best overall response of CR, PR, or SD (Cheson et al 2014) as determined by IRC.	62 months
Secondary	Event Free Survival (EFS)	Defined as the time from the date of randomization to the first documented disease progression as determined by radiographic disease assessment provided by IRC, the initiation of a new antilymphoma therapy, or death from any cause, whichever occurs first.	62 months
Secondary	Time To Next antiLymphoma Therapy (TTNLT)	Defined as the time from the date of randomization to the first documented administration of a new antilymphoma therapy.	62 months
Secondary	Progression-Free Survival on next antilymphoma therapy (PFS2)	Defined as the time from the date of randomization to the first documented disease progression as reported by the investigator after the initiation of a new antilymphoma therapy, death from any cause, or start of a third antilymphoma therapy since randomization in the study, whichever occurs first.	62 months
Secondary	Number of Treatment Emergent Adverse Events (TEAE's)	Adverse events reported for the first time or worsening of a pre-existing event after first dose of study drug/treatment.	62 months
