ClinConnect Summary

This clinical trial is looking at a new treatment for a type of cancer called marginal zone lymphoma (MZL). Specifically, it studies the combination of two drugs, Orelabrutinib and Zuberitamab, to see how effective and safe they are for patients who have not yet received treatment for MZL. Researchers want to find out how many patients achieve complete remission (meaning no signs of cancer) by the end of the treatment period.

To participate in the trial, you need to be at least 18 years old and have a confirmed diagnosis of CD20-positive MZL. You should also be in relatively good health, with a life expectancy of at least 12 weeks. Some important health conditions may disqualify you, such as certain heart problems or active infections. If you decide to join, you can expect close monitoring and support throughout the process. The trial is currently recruiting participants, so if you're interested, you can talk to your doctor for more information.
