A Study of LY4152199 in Participants With Previously Treated B-cell Malignancies (BAF_FRontier-1 )

Официальное название

BAF_FRontier-1, A First-in-Human, Phase 1 Trial to Assess Safety, Tolerability, and Preliminary Efficacy of LY4152199, a B-cell Activation Factor Receptor (BAFF-R) T-Cell Engager Bispecific Antibody in Adult Participants With Previously Treated B-cell Malignancies

Обзор

The purpose of this study is to find the best dose of the drug and measure the safety and efficacy of LY4152199 in participants with previously treated B-cell malignancies. Participants will have the option to continue taking LY4152199 until the study ends.

• Must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
• Estimated life expectancy of greater than or equal to (≥)12 weeks as judged by the Investigator.
• Participants with select tumor types must have measurable or assessable disease as defined below:

• Participants with lymphoma must have at least 1 bi-dimensionally measurable lesion or in the absence of measurable lymphadenopathy, documentation of bone marrow involvement.
• Participants with Waldenstrom macroglobulinemia (WM) must have measurable disease, defined as the presence of serum IgM with a minimum IgM level of greater than (>)2 times (×) upper limit of normal (ULN) based on local laboratory testing.
• Must be able to comply with inpatient/outpatient treatment, laboratory monitoring, and required clinic visits for the duration of trial participation.
• Must have adequate organ function.

Phase 1 Dose Escalation (Cohort A) Participants - Must have histologically confirmed relapsed/refractory B-cell malignancy.

Phase 1 Dose Optimization (Cohort B) Participants

\- Must have histologically confirmed relapsed/refractory diffuse large B-cell lymphoma (DLBCL) de novo or transformed from follicular lymphoma (FL).

Критерии исключения

All Participants

• Have current or had a history of severe allergic or anaphylactic reactions to monoclonal antibody therapy (or recombinant antibody-related fusion proteins).
• Prior treatment with B-cell activating factor receptor (BAFF-R) directed therapies (e.g., monoclonal antibody, CAR-T or bispecific antibody).
