Acerca de la investigación

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.

Part 1: Dose Finding

Participants will receive a step-up dosing regimen of MK-1045. During Cycle 1, participants will receive priming dose 1 of 1 mg MK-1045 on Day 1, priming dose 2 of 5 mg MK-1045 on Day 4, intermediate dose of 20 mg MK-1045 on Day 8, and then weekly (QW) target dose of 40-90 mg MK-1045 thereafter for up to approximately 2 years. At the discretion of physician investigator and after Sponsor consultation, participants who receive at least 3, 4-week treatment cycles and achieve a complete response may switch to an every two-weeks (Q2W) dosing regimen.

Biological: MK-1045 · Drug: Acetaminophen (or similar antipyretic) · Drug: Diphenhydramine (or similar antihistamine) · Drug: Dexamethasone · Biological: Tocilizumab · Biological: Tocilizumab biosimilar · Biological: Siltuximab

Part 2: Dose Expansion

Participants will receive MK-1045 QW at the recommended dose determined in Part 1 for up to approximately 2 years. At the discretion of physician investigator and after Sponsor consultation, participants who receive at least 3, 4-week treatment cycles and achieve a complete response may switch to a Q2W dosing regimen.

Qué evalúan los investigadores

Estas medidas indican qué se estudia. No prueban que un tratamiento funcione.

Medidas principales

Cohort A Part 1: Number of Participants Who Experience Dose-Limiting Toxicity (DLT)

Plazo: 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

Plazo: 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

Plazo: 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)

Plazo: 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).

Medidas secundarias

Cohort A Part 2: Number of Participants Who Experience an AE

Plazo: Up to approximately 27 months

An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment.

Cohort A Part 2: Number of Participants Who Discontinue Study Treatment Due to an AE

Plazo: Up to approximately 24 months

An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment.

Cohort A Parts 1 and 2: Duration of Response (DOR)

Plazo: Up to approximately 66 months

For participants who demonstrate a CR, CRi, nPR, or PR per iwCLL Criteria 2018 as assessed by BICR, DOR is defined as the time from the first documented evidence of CR, CRi, nPR, or PR until disease progression or death due to any cause, whichever occurs first.
