A Phase I Trial of Evorpacept, Lenalidomide and Rituximab for Patients with B-cell Non-Hodgkin Lymphoma.

ABSTRACT:

Introduction

SIRPα+ macrophages can mediate resistance to lenalidomide and rituximab (R2) in patients with B-cell non-Hodgkin lymphoma (B-NHL). Evorpacept (ALX148) is a novel CD47 blocker that abrogates interactions between lymphoma cells and SIRPα+ macrophages.

Methods

Adult patients with B-NHL who had received at least 2 prior lines of systemic therapy were included in this single arm phase I study (NCT05025800). Evorpacept was administered intravenously (IV), in a 28-day cycle, until progression, at two dose levels (DL): 30 mg/Kg on day (D) 1 and D15 (DL1), or 60 mg/Kg on day 1 (DL2); rituximab 375 mg/m2 IV was given weekly during cycle 1, and on D1 during cycles 2-6; lenalidomide 20 mg was given orally on D1-21 during cycles 1-6. Single-cell RNA sequencing was performed
