What this trial studies

This clinical trial is a multi-center, global, open-label study assessing the safety and efficacy of Brincidofovir in patients with relapsed or refractory lymphoma, including Extranodal Natural Killer/T-cell Lymphoma (ENKL). The study is divided into two parts, with a total enrollment of up to 43 participants, focusing on determining the maximum tolerated dose and preliminary efficacy of the treatment. Participants will be monitored for safety, tolerability, and pharmacokinetics of the drug across various cohorts. The trial is being conducted in multiple countries, including Japan, Korea, and Singapore.

Why it matters

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

How similar studies have gone: While this approach is novel for this specific patient population, similar studies have shown promise in treating other types of lymphoma with targeted therapies.
