Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients with relapsed or refractory acute myeloid leukemia who have measurable residual disease or TP53 mutations.

Probably not a fit

Patients with active autoimmune diseases or those who have previously received genetically modified cell therapies may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a first-in-human, multi-center, open-label phase 1/1b study evaluating the safety and preliminary efficacy of CER-1236, a novel chimeric engulfment receptor T-cell therapy, in patients with relapsed or refractory acute myeloid leukemia (AML) or TP53 mutated disease. The study consists of two parts: the first part focuses on determining the safety and recommended dose of CER-1236, while the second part assesses its efficacy in a larger cohort of patients. Participants will receive CER-1236 along with other treatments such as cyclophosphamide and fludarabine.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat forms of acute myeloid leukemia.

How similar studies have gone: While this approach is novel, similar therapies targeting specific receptors have shown promise in other hematological malignancies.
