Clinical summary

Summary

This study has two phases.

In Phase 1 (Dose Finding), people with advanced CD20+ B-cell non-Hodgkin lymphoma (NHL) will be enrolled. This Phase will have 2 sub-parts: Dose Escalation will determine the Maximum Toelrated Dose (MTD) or the highest tested dose, and Dose Assessment will determine the recommended pahse 2 dose (RP2D).

In Phase 2 (Dose Expansion), one or more cohorts will be selected with participants with subtypes of advanced CD20+ B-cell non-Hodgkin lymphoma.

Please note, Austin Health is currently only recruiting people with diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), primary mediastinal large B-cell lymphoma (PMBCL) and Mantle Cell Lymphoma (MCL).
