A Study of Escalating Doses of DCDS0780A in Participants With Relapsed or Refractory B-Cell Non-Hodgkin's Lymphoma

27. august 2019 oppdatert av: Hoffmann-La Roche

An Open-label, Multicenter, Phase 1/1b Dose Escalation Study Evaluating the Pharmacokinetics, Safety, Tolerability, and Preliminary Efficacy of DCDS0780A, Alone or in Combination With Rituximab, or Obinutuzumab, in Patients With Relapsed/Refractory B-Cell Non-Hodgkin's Lymphoma

This open-label, multicenter, Phase 1/1b study will evaluate the safety, tolerability, and pharmacokinetics of increasing doses of DCDS0780A in participants with relapsed or refractory B-cell non-Hodgkin's lymphoma. In the combination portion of the study, the safety and tolerability of DCDS0780A in combination with rituximab or obinutuzumab will be assessed.
