Disease: Relapsed or Refractory Acute Myeloid Leukemia, AML, (NCT06128044)

Disease info:

Leukaemia is cancer of the white blood cells which are responsible for fighting infection. In leukaemia, the bone marrow produces abnormal levels of white blood cells. Acute myeloid leukaemia (AML) starts in the bone marrow but often quickly spreads into the bloodstream. AML sometimes spreads to other parts of the body such as the lymph nodes, liver, central nervous system and testicles. 

Commonly, AML develops from cells other than lymphocytes that would normally develop into white blood cells. The World Health Organization (WHO) divides AML into several subtypes based off genetic association. AML is also known as acute myelocytic leukaemia, acute myelogenous leukaemia, acute granulocytic leukaemia, and acute non-lymphocytic leukaemia.

Relapsed refers to when a patient has received active treatment, went off treatment and then the disease came back, whereas refractory refers to disease that is progressing despite active treatment.

The American Cancer Society estimates approximately 20,380 cases of AML will be diagnosed in the U.S. in 2023, and approximately 11,310 deaths. AML is predominantly found in adults and is one of the most common types of leukaemia in adults.

Status: Active not recruiting


CB-012 is an allogeneic chimeric antigen receptor (CAR-T) cell therapy that targets C-type lectin-like molecule-1 (CLL-1). This is a Phase 1 study to evaluate the safety, preliminary efficacy, and pharmacokinetics, of CB-012 (the study treatment) in adults with acute myeloid leukemia (AML) that has come back after prior treatment (relapsed) or did not respond or is no longer responding to other treatment (refractory). Participants must have received at least 1 but not more than 3 prior lines of treatment for AML .
