Study Details

Study Description

Brief Summary

The purpose of this study is to evaluate the safety and efficacy of nemtabrutinib (formerly ARQ 531) in participants with hematologic malignancies of chronic lymphocytic leukemia (CLL)/ small lymphocytic lymphoma (SLL), Richter's transformation, marginal zone lymphoma (MZL), mantle cell lymphoma (MCL), follicular lymphoma (FL), and Waldenström's macroglobulinemia (WM).

    Primary Outcome Measures

    1. Part 1: Number of participants experiencing dose-limiting toxicities (DLTs) [Up to ~56 days (Cycles 1-2, cycle = 28 days)]

      DLTs will be defined as toxicities observed during the first 2 cycles (8 weeks) of Part 1 and include: Grade ≥3 nonhematologic toxicity (except Grade 3 nausea, vomiting, diarrhea, rash, fatigue, and uncontrolled hypertension which will not be considered a DLT unless lasting ≥72 hours despite optimal supportive care); Grade 4 hematologic toxicity lasting >7 days (except Grade 3 lymphocytosis, Grade 4 platelet count decreased of any duration, or Grade 3 platelet count decreased if associated with bleeding); any Grade 3 or Grade 4 nonhematologic laboratory abnormality if values result in drug-induced liver injury, or medical intervention is required, or the abnormality leads to hospitalization, or the abnormality persists for >1 week (with exceptions); missing >25% of nemtabrutinib doses as a result of drug-related adverse events (AEs) during the first 2 cycles (8 weeks); Grade 5 toxicity.

    2. Part 1: Number of participants experiencing adverse events (AEs) [Up to ~78 months]

      An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants experiencing AEs will be reported for Part 1.

    3. Part 1: Number of participants discontinuing study treatment due to AEs [Up to ~78 months]

      An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants discontinuing study treatment due to an AE will be reported for Part 1.
