About

This is a first in human, multi center, open label, phase 1/1b study to evaluate the safety and preliminary efficacy of CER-1236 in patients with relapsed/refractory (R/R), measurable residual disease (MRD) positive acute myeloid leukemia (AML), or TP53mut disease.

Full description

CER-1236 is a first in class chimeric engulfment receptor T-cell therapy candidate that targets the Tim4 ligand.

This is a first in human, multi center, open label, phase 1/1b study to evaluate the safety and preliminary efficacy of CER-1236 in patients with relapsed/refractory (R/R), measurable residual disease (MRD) positive acute myeloid leukemia (AML), or TP53mut disease.

The study is divided into Part 1 (escalation phase) and Part 2 (expansion phase).

Part 1 (Escalation Phase): The primary objectives of Part 1 are to define the safety of different doses of CER-1236 and to define the recommended dose for Part 2 (RP2D) of CER-1236.

Part 2 (Expansion Phase): The objective of the Part 2 expansion cohort is to evaluate the safety and efficacy of CER-1236 in patients with acute myeloid leukemia.
