A Phase 2, Open-label, Multicenter Study to Determine the Safety, Tolerability, and Efficacy of MK-1045 in Participants With Hematologic Malignancies

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.

Inclusion: Has histologically confirmed chronic lymphocytic leukemia (CLL)/small lymphocytic leukemia (SLL) active disease that is relapsed/refractory (r/r) to prior therapy; Has confirmed CD19-positive disease; If human immunodeficiency virus (HIV)-positive, has well-controlled HIV on antiretroviral therapy; If hepatitis B surface antigen (HBsAg)-positive, has undetectable hepatitis B virus (HBV) viral load; If has a history of hepatitis C virus (HCV) infection, has undetectable HCV viral load.

Exclusion: Has not adequately recovered from major surgery or has ongoing surgical complications; Has a history of serious cardiovascular and cerebrovascular diseases; Has a history or presence of central nervous system disease; Is HIV-infected with a history of Kaposi's sarcoma and/or Multicentric Castleman's Disease; Has a known additional malignancy that is progressing or required active treatment within the past 2 years; Has active autoimmune disease (not related to underlying leukemia diagnosis) that required systemic treatment in the past 2 years; Has any active acute graft versus host disease (GvHD) or active chronic GvHD requiring systemic treatment; Has active infection requiring systemic therapy; Has a diagnosis of immunodeficiency; Has a diagnosis of Richter Transformation.
