This study aims to evaluate the safety, tolerability, pharmacodynamic, and pharmacokinetic (PK) of nemtabrutinib (formerly ARQ 531) tablets in selected participants with relapsed or refractory hematologic malignancies. No formal hypothesis testing will be performed for this study.
This study includes 2 parts: Phase 1 (dose escalation) and Phase 2 (dose expansion). In Phase 1, participants will enroll using 3+3 dose escalation design. The starting dose of nemtabrutinib in oral tablet form was 5mg/day continuously. Dose escalation will continue until the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) and dosing schedule is reached based on protocol-defined dose limiting toxicity (DLT). After the determination of the RP2D, 9 expansion cohorts will be initiated to evaluate the safety, tolerability, and efficacy of nemtabrutinib at RP2D in participants with specifically defined disease.

| Nemtabrutinib | Drug | Nemtabrutinib will be orally administered once per day under fasted conditions (1 hour prior to or 2 hours after a meal) and is available in tablets in strengths of 5 mg or 20 mg.

| Measure | Description | Time Frame |
|---|---|---|
| Phase 1: Number of Participants Experiencing Dose Limiting Toxicity (DLT) | DLT is defined by the occurrence of any of the following treatment emergent adverse event (TEAE) unless unequivocally due to the underlying malignancy or an extraneous cause within the first 28 days of study treatment (for dose escalation only) and graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.03. Any Grade 5 TEAE, any Grade 3 nonhematological TEAE except alopecia, nausea, vomiting, diarrhea, and transient Grade 3 laboratory abnormalities which recover within 1 week without intervention, any Grade 3 hematological TEAE that does not recover to Grade 1 or baseline within 7 days with the exception of Grade 3 lymphocytosis, which is considered to be an expected outcome of BTK inhibition, any Grade 4 nonhematological and hematological TEAE, or any other toxicity that in the view of the investigator represents a clinically significant hazard to the participant. | Cycle 1 (up to 28 days) |
| Phase 1: Number of Participants Who Experienced an Adverse Event (AE) | An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The number of participants who experienced an AE will be reported. | Up to approximately 86 months |
| Phase 1: Number of Participants Who Discontinued Study Treatment Due to an AE | An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The number of participants who discontinued study treatment due to an AE will be reported. | Up to approximately 86 months |
