| Objective Response Rate (ORR) per International Workshop on Chronic Lymphocytic Leukemia (iwCLL) Criteria 2018 as Assessed by the Investigator | ORR per iwCLL criteria 2018 is defined as the percentage of participants achieving a complete response (CR), complete response with incomplete bone marrow (BM) recovery (CRi), nodular partial response (nPR) or partial response (PR). CR is defined as meeting the following criteria: no lymph nodes ≥1.5 cm, spleen size <13 cm, liver normal; no constitutional symptoms, normal lymphocyte count, platelets ≥100 x 10^9/L; hemoglobin ≥11 g/dL; and normocellular marrow (no CLL cells or B lymphoid nodules). CRi is defined as meeting CR criteria but with incomplete bone marrow recovery. nPR is defined as having features of CR but with lymphoid nodules in the marrow. PR is defined as ≥50% decrease in ≥2 of the following: lymph nodes, liver and/or spleen size, lymphocytes PLUS ≥1 of the following met: platelets ≥100 x 10^9/L or >50% increase from screening, hemoglobin ≥11 g/dL or >50% increase from screening, CLL cells or B lymphoid nodules in marrow. |

| Time to Maximum Concentration (Tmax) of Nemtabrutinib | Tmax is the time to reach maximum concentration of nemtabrutinib. Blood samples collected at designated timepoints will be used to determine Tmax. | Day 1 of Cycles 1 and 2: Pre-dose,1, 2, 4, 6, 8, and 24 hours post-dose; Day 1 of Cycle 3: pre-dose and 2 hours post-dose (up to ~57 days). Each cycle is 28 days |
| Up to ~ 35 months |
| ORR per International Workshop on Waldenström's Macroglobulinemia (IWWM) Criteria 2014 as Assessed by the Investigator | ORR per IWWM criteria 2014 is defined as the percentage of participants achieving a CR, very good partial response (VGPR), or PR. CR is defined as all lymph nodes are normal in size (none ≥15 mm), liver and spleen normal in size, serum immunoglobulin M (IgM) values in the normal range, disappearance of monoclonal protein by immunofixation (confirmation needed with a second immunofixation at any subsequent timepoint), and no histological evidence of BM involvement. VGPR is defined as ≥50% decrease from baseline in sum of product of diameter (SPD) of lymph nodes (if abnormal at baseline) ≥50% decrease from baseline in the abnormal portion of the spleen (if previously abnormal) and ≥90% decrease from baseline in serum IgM or serum IgM values in normal range. PR is defined as ≥50% decrease from baseline in SPD of lymph nodes (if abnormal at baseline) ≥50% decrease from baseline in serum IgM and ≥50% decrease from baseline in the abnormal portion of the spleen (if previously abnormal). | Up to ~ 35 months |
| ORR per Lugano Criteria 2014 as Assessed by the Investigator | ORR per Lugano criteria 2014 is defined as the percentage of participants achieving a CR or PR. CR defined as EITHER CR by imaging (computed tomography [CT]): all lymph nodes normal (none ≥15 mm) and normal liver and spleen OR complete metabolic response (CMR): assessing fluorodeoxyglucose (FDG) metabolic activity in lymphomatous lesions AND bone marrow normal by morphology. PR defined as EITHER PR by imaging (CT) with ≥50% decrease in the SPD of target lesions, no worsening of nontarget lesions, no new lesions and ≥50% spleen abnormal portion OR Partial Metabolic Response (PMR) with no new lesions and decreased overall uptake AND residual BM abnormalities; OR CR by imaging with residual BM abnormalities; OR PR by imaging without residual BM abnormalities. | Up to ~ 35 months |
