Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients with histologically confirmed DLBCL who have received two prior lines of therapy and are unresponsive to their last treatment.

Probably not a fit

Patients with primary CNS lymphoma or those who have not recovered from previous treatment toxicity may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is an open-label, single-arm, multi-center phase 2 study aimed at assessing the efficacy and safety of abexinostat, an oral histone deacetylase (HDAC) inhibitor, in patients diagnosed with relapsed or refractory diffuse large B-cell lymphoma (DLBCL). Participants will receive abexinostat as a monotherapy after having undergone two prior standard therapy lines, including anti-CD20 antibody and cytotoxic therapy. The study will measure the drug's effectiveness and safety profile in this specific patient population.

Why it matters

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

How similar studies have gone: Other studies involving HDAC inhibitors have shown promise in treating various cancers, suggesting potential for success with this approach.
