Can a Chemo-Transplant combo rescue patients whose leukemia resists standard treatment?
NCT ID NCT01188174
First seen Sep 14, 2026 · Last updated Sep 15, 2026 · Updated 1 time
Summary
This trial tests a treatment strategy for adults with acute myeloid leukemia (AML) that did not respond to standard induction chemotherapy. Participants receive clofarabine and intermediate-dose Ara-C chemotherapy, followed by a reduced-intensity allogeneic stem cell transplant using donor cells. The goal is to see whether this sequential approach improves survival at two years after transplant. The trial enrolls adults aged 18 to 55 who have a suitable matched donor.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- clofarabine combined with intermediate-dose cytarabine (Ara-C) chemotherapy, followed by a reduced-intensity allogeneic stem cell transplant
- What this could lead to
- If it works, this approach could offer a path to long-term remission for adults whose AML did not respond to standard induction chemotherapy, a group with few good options.
- What could go wrong
- The trial is small and early-stage, so results may not hold up in larger studies. The treatment combines intensive chemotherapy with a donor stem cell transplant, which carries serious risks including infections, graft-versus-host disease, and organ damage.

Inclusion Criteria: * Confirmed diagnosis of AML in the status of primary induction failure (i.e. persistent leukemia after 2 courses of induction chemotherapy or persisting bone marrow hypoplasia fol-lowing induction chemotherapy +/-minimal residual disease) * Age: 18-55 years * Availability of an HLA identical family donor OR unrelated donor with matching in 10/10 alleles (HLA-A, B, C, DRB1, DQB1) or maximum of 1 allele or antigen mismatch OR family donor with maximum 1 allele mismatch. * Have adequate renal and hepatic functions as indicated by the following laboratory values: * Serum creatinine ≤1.0 mg/dL; if serum creatinine \>1.0 mg/dL, then the estimated glomerular filtration rate (GFR) must be \>60 mL/min/1.73 m² as calculated by the Modification of Diet in Renal Disease equation where Predicted GFR (ml/min/1.73 m2) = 186 x (Serum Creatinine)-1.154 x (age in years)-0.023 x (0.742 if patient is female) * Serum bilirubin ≤1.5 mg/dL × upper limit of normal (ULN) * Aspartate transaminase (AST)/alanine transaminase (ALT) ≤2.5 × ULN * Alkaline phosphatase ≤2.5 × ULN Exclusion Criteria: * Documented chloroma * Patients having AML M3 * Documented leukemic infiltration of CNS/cerebrospinal fluid * Karnofsky performance score below \< 60% * Acute or chronic heart failure * HIV infection, chronic viral hepatitis * Severe neurological or psychiatric disorders * Any circumstances that preclude the use of the drugs used within the protocol * Prior allogeneic or autologous stem cell transplantation * \> 3 courses of prior chemotherapy * Denied informed consent * Pregnancy or denied of effective contraceptive method
