A Study of Nemtabrutinib Plus Venetoclax vs Venetoclax + Rituximab (VR) in Second-line (2L) + Relapsed/Refractory (R/R) Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma (CLL/SLL) (MK-1026-010/BELLWAVE-010).

May 14, 2026 updated by: Merck Sharp & Dohme LLC

A Phase 3, Open-label, Randomized Study to Compare the Efficacy and Safety of Nemtabrutinib (MK-1026) Plus Venetoclax Versus Venetoclax Plus Rituximab in Participants With Relapsed/Refractory Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma Following at Least 1 Prior Therapy (BELLWAVE-010)

The purpose of this study is to assess the safety and tolerability and to confirm the dose of nemtabrutinib in combination with venetoclax in participants with R/R CLL/SLL. The primary study hypotheses are that the combination of nemtabrutinib plus venetoclax is superior to VR with respect to progression-free survival (PFS) per 2018 International Workshop on Chronic Lymphocytic Leukemia (iwCLL) criteria as assessed by blinded independent central review (BICR).

DLT evaluation period is defined as 8 weeks after the first dose of the combination treatment of nemtabrutinib plus venetoclax Cycle 2 Day 1 in Part 1 + 4 weeks follow up. Each cycle is 4 weeks. DLTs are: 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 or venetoclax doses as a result of drug-related adverse events during the first 2 cycles; Grade 5 toxicity.
Up to approximately 12 Weeks
Part 1: Number of Participants Experiencing Adverse Events (AEs)
Time Frame: Up to approximately 28 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.
Up to approximately 28 months
Part 1: Number of Participants Discontinuing Study Treatment Due to AEs
Time Frame: Up to approximately 25 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 AEs will be reported for Part 1.
Up to approximately 25 months
Part 2: PFS per the 2018 International Workshop on Chronic Lymphocytic Leukemia (iwCLL) Criteria as Assessed by Blinded Independent Central Review (BICR)
Time Frame: Up to approximately 71 months
PFS is defined as the time from randomization to the first documented disease progression per iwCLL criteria 2018 as accessed by BICR, or death due to any cause, whichever occurs first. PFS will be presented.
Up to approximately 71 months

Secondary Outcome Measures

Measure Description
Time Frame
Part 2: Overall Survival (OS)
Time Frame: Up to approximately 108 months
OS, defined as the time from randomization to death due to any cause. OS will be presented.
Up to approximately 108 months
Part 2: Undetectable Minimal Residual Disease (MRD) Rate in Bone Marrow as Assessed by Central Laboratory
Time Frame: Up to approximately 46 months
Undetectable MRD, defined as <1 leukemic cell per 10,000 cells (MRD <10-4) in bone marrow. The MRD rate will be presented.
Up to approximately 46 months
Part 2: Objective Response Rate (ORR) per iwCLL Criteria 2018 as Assessed by BICR
Time Frame: Up to approximately 71 months
OR, defined as complete response/remission (CR), complete response with incomplete count recovery (CRi), nodular partial remission (nPR), or partial remission (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 hypocellular bone marrow. 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. ORR will be presented.
Up to approximately 71 months
Part 2: Duration of Response (DOR) per iwCLL Criteria 2018 as Assessed by BICR
Time Frame: Up to approximately 108 months
DOR, defined as the time from the first documented evidence of CR, CRi, nPR, or PR that led to response until disease progression or death due to any cause, whichever occurs first. 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 hypocellular bone marrow. 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. DOR will be presented.
Up to approximately 108 months
Part 2: Number of Participants Experiencing AEs
Time Frame: Up to approximately 28 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 2.
Up to approximately 28 months
Part 2: Number of Participants Discontinuing Study Treatment Due to AEs
Time Frame: Up to approximately 25 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 AEs will be reported for Part 2.
Up to approximately 25 months
