Surovatamig (AZD0486) as Monotherapy in Participants With Relapsed/Refractory (R/R) B-cell NHL

This is a Phase 2 global, multi-center, open-label study to assess the efficacy, safety and tolerability of surovatamig (AZD0486) monotherapy in adult participants with relapsed/refractory B-cell non-Hodgkin lymphoma (NHL) who have received at least two prior lines of therapies.
