New chemo cocktail aims to beat back leukemia relapse
NCT ID NCT00932412
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 2 trial tests whether a combination of clofarabine and intermediate-dose cytarabine (CLARA) works better than high-dose cytarabine (HDAC) alone as consolidation therapy for younger adults (18-60) with newly diagnosed acute myeloid leukemia (AML). After initial remission, 735 participants were randomized to receive three cycles of either CLARA or HDAC. The main goal is to see which regimen leads to longer disease-free survival.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- clofarabine and cytarabine (CLARA) vs high-dose cytarabine (HDAC)
- What this could lead to
- If CLARA works better, it could offer a more effective consolidation option for younger AML patients, potentially reducing relapse risk.
- What could go wrong
- This is a phase 2 trial, so results are preliminary. The CLARA combo may not improve outcomes over standard HDAC and could have different side effects.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria at registration: 1. Age 18 years or more and less than 60 years 2. With: A morphologically proven diagnosis of AML according to the WHO classification, cytogenetically (standard karyotype, FISH-MLL) and molecularly (FLT3, CEBPA, NMP1) defined. 3. ECOG (Eastern Cooperative Oncology Group) performance status 0 to 2. 4. Have adequate renal and hepatic function as indicated by the following laboratory values: * Creatinine clearance (calculated by the cockcroft and Gault method) ≥ 40mL/min; * AST (Aspartate amino transférase) and ALT (Alanine Amino Transférase ) \< or = 2.5N; total bilirubin \< or = 2N (unless related to the underlying disease). 5. Cardiac function determined by radionuclide or echography within normal limits. 6. Women of child-bearing potential (i.e. women who are pre-menopausal or not surgically sterile) must use acceptable contraceptive methods, and must have a negative serum or urine pregnancy test within 2 weeks prior the beginning treatment on this trial. 7. Must be able and willing to give written informed consent. 8. The subject must be covered by a social security system. Exclusion Criteria at registration: 1. Patients with AML with favorable risk cytogenetics: M3-AML; CBF-AML including t(8:21), inv(16), or t(16;16) AML. 2. Ph-positive AML. 3. AML following diagnosed myeloproliferation or patient with prior history of MDS known for more than 3 months 4. Prior treatment with chemotherapy or radiotherapy for another tumor. 5. Prior tumor, if not stable for at least two years, except in-situ carcinoma and skin carcinoma 6. Compromised organ function judged to be lifethreatening by the Investigator. 7. Positive serology for HIV (Human Immunodeficiency Virus), HBV (Hepatitis B Virus) and HBC (Hepatitis C Virus)(except post vaccination) 8. Uncontrolled active infection of any kind or bleeding. Patients with infections who are under active treatment with antibiotics and whose infections are controlled may be entered to the study. 9. Other active malignancy. 10. Patients concurrently receiving any other standard or investigational treatment for their leukemia, with the exception of hydroxyurea. INCLUSION CRITERIA AT RANDOMIZATION 1. Patients with either in first CR/CRp after the first induction course or in first CR/CRp after salvage therapy. 2. ECOG performance status 0 to 2. 3. AST and ALT \< or = 2.5N; total bilirubin \< or = 2N. 4. Creatinine clearance ≥40mL/min (calculated by the cockcroft and Gault method or by MDRD (see http://nephron.org/cgi-bin/MDRD\_GFR/cgi) 5. Patient without HLA identical donor. EXCLUSION CRITERIA AT RANDOMIZATION 6. Patients belonging to the intermediate 1 risk group (CEBPA+ or NPM1+ without Flt3-ITD) in CR/CRp after the first induction course. These patients will go out of the study and receive consolidation cycles based on HD-AraC (Aracytine). 7. Known central nervous system involvement with AML. 8. Uncontrolled active infection of any kind or bleeding. 9. Compromized organ function judged to be lifethreatening by the Investigator. 10. Patient with HLA identical donor identified.
