Clinical Trial Summary

CB010A is a study evaluating safety, emerging efficacy, pharmacokinetics and immunogenicity of CB-010 in adults with relapsed/refractory B cell non-Hodgkin lymphoma after lymphodepletion consisting of cyclophosphamide and fludarabine.

Description:

This clinical trial is a first-in-human, Phase 1, multicenter, open-label evaluation of safety and emerging efficacy of CB-010 in adults with relapsed/refractory B cell non-Hodgkin lymphoma. The study is conducted in two parts: Part A is dose escalation following a 3 + 3 design, with sequential, prespecified, increasing doses. Part B is the expansion portion where patients will receive CB-010 at the dose determined in Part A.
