Tests treatment safety and results for Relapsed Large B-cell Lymphoma
Official title Study of Efficacy and Safety of CRC01 in Adult Large B-cell Lymphoma and B-cell Acute Lymphoblastic Leukemia Patients
ClinicalTrials.gov ID: NCT04836507
What this study is testing
What is CRC01?
CRC01 is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for relapsed large b-cell lymphoma.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This is a multi-center, phase I/II study to determine the efficacy and safety of CRC01 in adult patients with relapsed or refractory large B-cell lymphoma and B-cell Acute Lymphoblastic Leukemia.
- Phase 2: a mid-size study of how well it works
