简要总结
Study Design: Treatment, Randomized, Open Label, Parallel Assignment This study is an open randomized and controlled trial aiming at assessing the efficacy and safety of Idarubicin (IDA) at different doses of 8mg/m2 and 10mg/m2 combined with cytarabine as induction therapy for newly diagnosed Acute Myeloid Leukaemia (AML). All the recruited patients are allocated to group A ( 8mg/m2 group) or group B ( 10mg/m2) in random. It is advised that induction therapy should begain not late than 3 days after randomization. The regimens in detail can be refered in the therapy protocol.
详细描述
Idarubicin is a new generation of anthracyclines with high lipophilicity and is more permeable to cytomembrane and therefore is more cytotoxic to leukemic cells. It can pass through the blood brain barrier easily. so IDA has more advantages over other anthracyclines in prolonging the overall survival for AML. The induction therapy with idarubicin and cytarabine is now the first-line induction regimen for AML. Many clinical trails have indicated that the dosage of IDA is positively correlated with its effectiveness. But in China IDA has been used in varied dosages ranging from 6 to 12 mg/m2. In most Chinese hospitals, the usual dosage range of IDA is from 6 to 8 mg/m2 which may contribute to the much lower 5-year survival rates of AML reported in Chinese medical literature than those in foreign literature. What is the suitable dosage of IDA as induction therapy for Chinese AML population with the best efficacy but the lest increase of side effects? Till now there is no retrospective, randomized and multicentered clinical trails to answer this question on remission-inducing dosages of IDA. All the existing trials till now are just small- sampled , single-centered , retrospective and non-randomized which can not provide strong evidences .
This study aims at comparing two induction doses of 8mg/m2 and 10mg/m2 of IDA with the method of prospective randomized and multi-centered trial.The two doses of IDA have been used in many Chinese hospitals for many years, its effectiveness and safety have been recognized. This trail aims at the and side effects of IDA during induction therapy and its effect on the long-term survival of Chinese AML population, so it can provide strong evidences for optimal dosage of IDA for Chinese AML population.It can not only reduce the waste of medical social resources but also produce good social and economic benefits.
