Nemtabrutinib and Venetoclax for Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma
This study is testing how well two medications, nemtabrutinib and venetoclax, work together to treat chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). Nemtabrutinib is a kinase inhibitor that blocks a protein called BTK, which can help stop cancer cells from growing. Venetoclax is a BCL-2 inhibitor that helps kill cancer cells by blocking a protein they need to survive. The study aims to see if this combination can lead to undetectable minimal residual disease (MRD), meaning very few cancer cells are left after treatment. You may be able to join if you are at least 18 years old and have newly diagnosed CLL/SLL that has not been treated before. The current status of this study is unclear.
- Study design
- This study plans to enroll 25 participants. It is an interventional study, meaning participants will receive a specific treatment.
- What's involved
- You would undergo blood sample collection, bone marrow aspiration and biopsy, and CT scans. You would also take nemtabrutinib by mouth (PO). The primary endpoint is measured after 14 cycles of treatment, with each cycle lasting 28 days.
- Compensation
- Not stated in the trial record.
- Follow-up
- The primary goal is measured after 14 cycles of treatment (cycle length = 28 days). Other follow-up details are not specified.

Adequate bone marrow independent of growth factor support or infusion support at screening unless evidence shows that the cytopenia(s) is due to marrow involvement by CLL/SLL and/or disease-related immune thrombocytopenia, or anemia. If cytopenias are due to disease in the bone marrow any degree of cytopenias are allowed. Patients with active uncontrolled autoimmune cytopenias are excluded
Absolute neutrophil count (ANC) \>= 1000/mm\^3
Platelets \>= 50,000/mm\^3
Hemoglobin \>= 8 g/dL
Willing and able to participate in all required evaluations and procedures in this study protocol
Ability to understand the purpose and risks of the study and provide signed and dated informed consent and authorization to use protected health information
Participants assigned male sex at birth: If capable of producing sperm, the participant agrees to the following during the intervention period and for at least the time needed to eliminate each study intervention after the last dose of study intervention. The length of time required to continue contraception for each study intervention is:
Nemtabrutinib: 12 days
Abstains from penile-vaginal intercourse as their preferred and usual lifestyle (abstinent on a long-term and persistent basis) and agrees to remain abstinent OR
Uses contraception as detailed below unless confirmed to be azoospermic (vasectomized or secondary to medical cause, documented from the site personnel's review of the participant's medical records, medical examination, or medical history interview) as detailed below:
Uses a penile/external condom plus nonparticipant of childbearing potential who is not currently pregnant and should also be advised of the benefit for that partner to use an additional method of contraception, as a condom may break or leak.
Note: Participants capable of producing ejaculate whose partner is pregnant or breastfeeding must agree to use penile/external condom during each episode of sexual activity in which the partner is at risk of drug exposure via ejaculate.
Contraceptive use by participants capable of producing sperm should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. If the contraception requirements in the local label for any of the study interventions are more stringent than the requirements above, the local label requirements are to be followed
Participants assigned female sex at birth: A participant assigned female sex at birth is eligible to participate if not pregnant or breastfeeding, and at least one of the following conditions applies:
Is not a person of childbearing potential (POCBP) OR
Is a POCBP and:
Uses a contraceptive method that is highly effective (with a failure rate of \< 1% per year), with low user dependency, or is abstinent from penile-vaginal intercourse as their preferred and usual lifestyle (abstinent on a long-term and persistent basis), during the intervention period and for at least the time needed to eliminate each study intervention after the last dose of study intervention. The length of time required to continue contraception for each study intervention is:
Nemtabrutinib: 1 month
The investigator should evaluate the potential for contraceptive method failure (i.e., noncompliance, recently initiated) in relationship to the first dose of study intervention. Contraceptive use by POCBPs should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. If the contraception requirements in the local label for any of the study interventions are more stringent than the requirements above, the local label requirements are to be followed.

Medical history, menstrual history, and recent sexual activity has been reviewed by the investigator to decrease the risk for inclusion of a POCBP with an early undetected pregnancy

What this trial measures
- Presence of undetectable minimal residual disease (MRD)After 14 cycles of treatment (cycle length = 28 days)
As measured by Adaptive ClonoSeq next generation sequencing at a level of 10\^-6 in the peripheral blood after 14 cycles of treatment with nemtabrutinib and venetoclax. The rate of undetectable MRD will be calculated in all eligible patients who start any amount of study drug, and the 95% confidence interval will be provided with the estimated rate.
