Assessing the safety and effectiveness of ABBV-319 in treating certain types of B-cell lymphomas and leukemia

A First In Human Multicenter, Open-Label Study to Determine the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of ABBV-319 in B-cell Malignancies

Phase 1 Interventional AbbVie · NCT05512390

This study is testing a new drug called ABBV-319 to see if it can safely help adults with certain types of B-cell lymphomas and leukemia that haven't responded to other treatments.

What this trial studies

This clinical trial evaluates the safety, tolerability, and pharmacokinetics of ABBV-319, an investigational drug, in adult participants with relapsed or refractory diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), or chronic lymphocytic leukemia (CLL). The study consists of a dose escalation phase to determine appropriate dosing and a dose expansion phase to assess changes in disease activity. Approximately 154 adult participants will be enrolled to monitor adverse events and preliminary efficacy of the treatment.

Who should consider this trial

Good fit: Ideal candidates include adults with relapsed or refractory DLBCL, FL, or CLL who have measurable disease requiring treatment.

Not a fit: Patients who have not been diagnosed with B-cell malignancies or those with stable disease not requiring treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat B-cell malignancies.

How similar studies have performed: Other studies have shown promise with similar investigational therapies for B-cell malignancies, indicating potential for success in this approach.

Eligibility criteria

Inclusion Criteria:

* For dose escalation (Part 1) only: Participants with documented diagnosis of B-cell malignancies including those with histology based on criteria established by the World Health Organization (WHO), and measurable disease requiring treatment, as per the protocol.
* For the relapsed or refractory diffuse large b-cell lymphoma (DLBCL), follicular lymphoma (FL), and Chronic lymphocytic leukemia (CLL) dose expansion cohorts (Part 2) only: Participants with documented diagnosis of one of the B-cell malignancies noted in the protocol with histology based on criteria established by the WHO, and measurable disease requiring treatment, as per the protocol.
* Laboratory values meeting the criteria noted in the protocol.
* For participants previously treated with a CD19-targeting therapy (eg, CD19 monoclonal antibody) a core or excision tumor biopsy subsequent to the most recent CD19-targeting therapy must be collected.
* Participant must have measurable disease, as defined by the 2014 Lugano Classification.

Exclusion Criteria:

* Known active central nervous system (CNS) disease, or primary CNS lymphoma.
* Known active infection or clinically significant uncontrolled conditions as per the protocol.
