Efficacy and Safety of Cladribine in Combination With G-CSF,Low-dose Cytarabine and Aclarubicin in Newly Diagnosed Unfit Patients With Acute Myeloid Leukemia

In this study, the investigators conducted a phase II trial that evaluated the efficacy and safety of cladribine in combination with modified CAG regimen (low-dose cytarabine and aclarubicin) in elderly patients with AML.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The low-intensity chemotherapy were developed to reduce the early mortality and improve the benefit-risk ratio for longterm survival in elderly or unfit AML patients.Previous studies revealed that the standard dose of CAG regimen consisting of low-dose cytarabine and aclarubicin in combination with granulocyte colonystimulating factor (G-CSF) priming as an induction therapy was well-tolerated by patients and led to a complete remission (CR) rate of 50.0% in patients aged≥ 70 years. Cladribine (2-chlorodeoxyadenosine ) is a nucleoside analogue of anti-adenosine deaminase that has extensive antitumor activity in hematological tumor.The purine analog 2-CdA increases the uptake of Ara-C and the accumulation of its active cytotoxic metabolite 5α-triphosphate Ara-C (Ara-CTP) in leukemia cells. This finding suggests that synergy occurs between cladribine and cytarabine. In this study, the investigators conducted a phase II trial that evaluated the efficacy and safety of cladribine in combination with modified CAG regimen (low-dose cytarabine and aclarubicin) in unfit patients with AML.Patients will receive C-CAG regimen as follows: cladribine 5 mg/m2, d1-5; G-CSF 300 µg, d0-9; aclarubicin 10 mg, d3-6; cytarabine 10mg/ m2 q12h, SC, d3-9; 4 weeks per cycle. The participants are permitted to quit the study if complete remission (CR) was not achieved after two courses of chemotherapy.The participants will be treated for a total of six cycles unless disease progression or unacceptable side effects are observed or participants withdrew their consent.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
