Can a drug combo shrink Hard-to-Treat lymphoma tumors?
NCT ID NCT04477486
First seen Aug 28, 2026 · Last updated Aug 28, 2026
Summary
This Phase 2 trial tests whether adding venetoclax to ibrutinib can improve complete responses in Japanese adults with mantle cell lymphoma that has returned or not responded to treatment. Participants take both oral drugs for about 104 weeks, then continue ibrutinib alone until the disease worsens or side effects become intolerable. The study measures how many people achieve a complete response, meaning no detectable cancer, and also tracks safety and quality of life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- venetoclax combined with ibrutinib
- What this could lead to
- If the combination works, it could offer a more effective treatment option for people with mantle cell lymphoma that has returned or stopped responding to prior therapy.
- What could go wrong
- This is a small, early-phase study with about 12 participants, so results may not apply broadly. The combination may cause side effects, and the added benefit over ibrutinib alone is not yet proven.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Pathologically confirmed Mantle Cell Lymphoma (MCL) (tumor tissue) by local testing. * At least 1 measurable site of disease on cross-sectional imaging that is \>= 2.0 centimeters (cm) in the longest diameter and measurable in 2 perpendicular dimensions per Computed Tomography (CT). * At least 1, but no more than 5, prior treatment regimens for MCL including at least 1 prior rituximab/anti-CD20 containing regimen. * Failure to achieve at least partial response (PR) with, or documented disease progression after, the most recent treatment regimen. Exclusion Criteria: * Prior therapy with ibrutinib or other Bruton Tyrosine Kinase (BTK) inhibitors. * History of other malignancies, except: * Malignancy treated with curative intent and with no known active disease present for \>= 3 years before the first dose of study drug and felt to be at low risk for recurrence by treating physician. * Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease. * Adequately treated carcinoma in situ without evidence of disease. * History or current evidence of central nervous system lymphoma. * Treatment with any of the following within 7 days prior to the first dose of study drug: * Moderate or strong cytochrome P450 3A (CYP3A) inhibitors. * Moderate or strong CYP3A inducers. * Anticancer therapy, including chemotherapy, radiotherapy, small molecule, and investigational agents, and/or monoclonal antibody \<=21 days prior to the first dose of study drug.
