Study of Efficacy and Safety of CRC01 in Adult Large B-cell Lymphoma Patients

ClinConnect Summary

This clinical trial is testing a new treatment called CRC01 for adults with certain types of large B-cell lymphomas, which are cancers of the lymphatic system that have come back or did not respond to previous treatments. The goal of the study is to see how well CRC01 works and if it is safe for patients who have already undergone at least two rounds of chemotherapy. To join the trial, participants need to be at least 19 years old and have a confirmed diagnosis of one of the specified lymphoma types, along with some other health requirements.

If eligible and willing to participate, individuals can expect to receive CRC01 after meeting specific health criteria and undergoing certain tests. The study is currently recruiting participants, and those who join will be monitored closely to assess the effectiveness of the treatment and any side effects. It's important to note that participants will need to agree to use effective birth control methods during the study and for a period afterward. This trial offers a chance to access a potential new therapy while contributing to research that may help others in the future.
