ClinConnect Summary

This protocol corresponds to a multicenter, phase II, open, non randomized, designed to determine the efficacy of clofarabine and low-dose cytarabine combination in AML patients older than or equal to 60 years.

The trial is divided into pre-treatment and treatment (cycle / s of induction and consolidation) periods.The induction cycle consist of clofarabine at 20 mg/m2/day intravenously for 5 consecutive days plus cytarabine subcutaneously at 20 mg/m2/day for 14 consecutive days. If patients do not achieve CR they will receive a second course of induction with the same pattern. Consolidatio...

• 4. At least one of the following factors:
• • Older than or equal to 70 years
• • Prior hematological disorder (AHD)
• • ECOG performance status 2
• * Unfavorable karyotype (ie, adverse) defined as any cytogenetic profile except the presence of any of the following:
• • t(8;21)(q22;q22) inv(16)(p13q22) or t(16;16)(p13;q22) t(15;17)(q22;q12) and variants
• • 5. Provide written informed consent form.
• • 6. Being able to comply with study procedures and follow-up evaluations.
• • 7. Not to be fertile or willing to use a method of birth control during the study until the end of the last visit of the treatment.
• 8. Adequate renal and hepatic function as follows:
• • Total bilirubin \<= 1,5 x upper of institutional normal limit (ULN) and
• • AST y ALT \<=2,5 x ULN and
• • Serum creatinine \<=1,0 mg/dL of serum creatinine \<01,0 mg/dL, then, glomerular filtration rate (GFR) estimated must be \>60 mL/min/1,73 m2 calculated from the equation of the Modification of Diet in Renal Disease (MDRD).
• 9. Adequate cardiac function determined by at least one of the following:
• • Left ventricular ejection fraction (LVEF) \>=40% measured by echocardiography in Multiple Gated Acquisition (MUGA) scan or isotope angiography or
• • Left ventricular fractional shortening \>=22% measured by echocardiography.
• Exclusion Criteria:
• • 1. Diagnosis of acute promyelocytic leukaemia (APL) in French-American-British classification M3º or attending to the WHO classification t(15;17)(q22;q12), (PML/RAR and variants).
• • 2. Pre-treatment with clofarabine.
• • 3. Previous treatment for AML or a hematological disorder AHD (excluding palliative care, hydroxyurea, hematopoietic cytokines or lenalidomide \[the latter only for a specific AHD\]). Hematopoietic cytokines and lenalidomide should not have been administered within the 14 days preceding the first dose of study drug. If it is received any previous treatment for AML or AHD within the time limits allowed, drug-related toxicity, must have recovered to Grade 1 or less before the first dose of study drug.
• • 4. Previous hematopoietic stem cell transplantation (HSCT).
• • 5. External beam pelvic radiotherapy.

• 7. Inadequate renal and hepatic function as follows:
• • Total bilirubin \>1,5 x institutional upper limit normal (ULN) provided it is not attributable to the very LMA or
• • AST y ALT \>2,5 x ULN provided it is not attributable to the very LMA or
• • Serum creatinine \>1,0 mg/dL provided that the glomerular filtration rate (GFR) estimated to be ≤60 mL/min/1,73 m2 calculated by the equation of the Modification of Diet in Renal Disease (MDRD).
• 8. Inadequate cardiac function determined by at least one of the following:
• • Left ventricular ejection fraction \<40% measured by echocardiography in Multiple Gated Acquisition (MUGA) or isotope angiography; or
• • Left ventricular fractional shortening \<22% measured by echocardiography.
• • 9. Poor general condition ECOG 3-4.
• • 10. Refusal to sign informed consent form.
• • 11. Inability to comply with study visits and inspections.
• • 12. Psychiatric disorders that could interfere with the consent, participation or monitoring of the study.
• • 13. Fungal Systemic disease, bacterial, viral or other uncontrolled infection (defined as manifestation of signs / symptoms related to ongoing infection and without improvement, although receiving adequate antibiotic therapy or other treatment).
• • 14. Any other concomitant serious disease or a history of severe organ dysfunction or heart, kidney, liver or other organ system which may involve the patient in excessive risk when exposed to clofarabine.
• 15. Diagnosis of another malignancy neoplasia, unless the patient has been disease-free for at least five years after completing an attempt curative therapy with the following exceptions:
• • Patients with non-melanoma skin cancer, carcinoma in situ or cervical intraepithelial neoplasia, irrespective of the duration of disease-free period, are eligible for the study if it has finalized a definitive treatment for the disease.
• • Patients with prostate cancer confined to the organ without evidence of recurrent or progressive disease based on figures for the prostate specific antigen (PSA) are also candidates for the study if hormonal therapy has been initiated or has made a radical prostatectomy.
• • 16. Clinical evidence which may indicate central nervous system (CNS) leukemia unless lumbar puncture to confirm the absence of leukemic blasts in the cerebrospinal fluid (CSF).
• • 17. Previous positive test for human immunodeficiency virus (HIV).
