Phase 1 Study of Autologous SIRPα-low Macrophages (SIRPant-M) Administered by IT- Injection Alone or in Combination With Focal External-Beam Radiotherapy in Participants With Relapsed or Refractory Non-Hodgkin's Lymphoma
SIRPant Immunotherapeutics, Inc.
Summary
The goal of this study is to test SIRPant-M (RB-1355) , an autologous cell therapy, alone or in combination with focal external-beam radiotherapy in participants with relapsed or refractory non-Hodgkin's lymphoma (NHL). Two dose levels of SIRPant-M are being tested. The main question this study aims to answer is if SIRPant-M alone or in combination with radiotherapy is safe and well-tolerated.
Description
This is an open-label phase 1 study of SIRPant-M studied in serial cohorts either alone (monotherapy), or combined with low-dose focal external-beam radiotherapy (XRT) in patients with relapsed- or refractory Non-Hodgkin's lymphoma (NHL). Both B-cell and certain T-cell NHL (select PTCL; CTCL) are eligible. The primary objective of the study is to assess the safety and tolerability of autologous SIRPant-M, delivered by 3 intra-tumoral injection, given either alone or combined with 2.5 Gy focal XRT. A course (cycle) of SIRPant-M (RB-1355) is prepared from a single mononuclear apheresis, and com…
