研究概览
简要总结
Researchers are looking for new ways to treat people with B-cell cancers. In this trial, researchers will look at chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL). These are blood cancers that affect B-cells in the blood, bone marrow, or lymph nodes.
The goals of this trial are to learn about:
- The safety of MK-1045 and if participants tolerate it. Tolerate means participants will receive trial treatment unless they need to stop treatment due to health problems.
- The number of participants who respond. Respond means the number of cancer cells goes down or signs of cancer go away.

结局指标
主要结局
Cohort A Part 1: Number of Participants Who Experience Dose-Limiting Toxicity (DLT)
时间窗: Up to approximately 29 days
DLT will be defined as any drug-related adverse event (AE) observed during the DLT evaluation period that results in a change to a given dose or a delay in initiating the next dose.
Cohort A Part 1: Number of Participants Who Experience an AE
时间窗: Up to approximately 27 months
An AE is defined as 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.
Cohort A Part 1: Number of Participants Who Discontinue Study Treatment Due to an AE
时间窗: Up to approximately 24 months
An AE is defined as 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.
Cohort A Parts 1 and 2: Objective Response Rate (ORR)
时间窗: Up to approximately 66 months
ORR is defined as the percentage of participants with complete response (CR), complete response with an incomplete recovery of the participant's bone marrow (CRi), nodular partial response (nPR), or partial response (PR), per International Workshop on Chronic Lymphocytic Leukemia (iwCLL) Criteria 2018 as assessed by blinded independent central review (BICR).
