Study Details
Study Description
Brief Summary
The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of parsaclisib in the treatment of Japanese participants diagnosed with previously-treated B-cell lymphoma.

Outcome Measures
Primary Outcome Measures
- Number of participants with treatment-emergent adverse events (TEAEs) [Up to approximately 1 year]
TEAE defined as any adverse event either reported for the first time or worsening of a pre-existing event after first dose of study drug.
Secondary Outcome Measures
- Changes in pharmacodynamic (PD) markers of B-cell activation in plasma [Up to 24 weeks]
Markers of B-cell activation (eg, B-cell activating factor, interleukin-10, B-cell attracting chemokine) and other plasma analytes will be analyzed for correlation with safety and clinical outcome.
- Objective response rate [Up to approximately 1 year]
Defined as the percentage of subjects with complete response (CR)/complete metabolic response (CMR) and partial response (PR)/ partial metabolic response (PMR), as determined by investigator assessment of response according to response criteria for lymphomas.
- Duration of response [Up to approximately 1 year]
Defined as the time from first documented evidence of CR/CMR or PR/PMR until disease progression or death from any cause among subjects who achieve an objective response.
- Progression-free survival [Up to approximately 1 year]
Defined as the time from the date of the first dose of study drug until the earliest date of disease progression or death from any cause.
