New drug ABBV-319 takes aim at Hard-to-Treat blood cancers
NCT ID NCT05512390
First seen Jun 27, 2026 · Last updated Aug 28, 2026 · Updated 1 time
Summary
This early-stage trial tests an investigational drug called ABBV-319 in about 154 adults with certain B-cell cancers (diffuse large B-cell lymphoma, follicular lymphoma, or chronic lymphocytic leukemia) that have returned or not responded to standard treatments. The study has two parts: first, finding a safe dose, then checking how well that dose controls the cancer. Participants receive the drug by IV every 21 days and are closely monitored for side effects and tumor response.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ABBV-319 (an investigational drug given by IV infusion)
- What this could lead to
- If it works, this could point toward a new treatment option for people with certain B-cell cancers that have not responded to other therapies.
- What could go wrong
- This is a very early Phase 1 trial focused on safety and dosing, not yet on effectiveness. The drug may not shrink tumors or could cause serious side effects. Results may not apply to all patients.

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.
