简要总结
In this single-center, open-label, no control,prospective clinical trial, a total of 30 Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ALL) patients will be enrolled. Dasatinib 100 mg per day will be given orally along with combination chemotherapy starting day 8 of induction chemotherapy. Dasatinib will be given continuously (if it's tolerable) for 2 years since achievement of complete remission (CR) as part of consolidation chemotherapy and maintenance therapy.Patients can receive allogeneic hematopoietic stem cell transplantation (HSCT) or autologous HSCT whenever possible during their first CR. Otherwise, they will finish the consolidation chemotherapy. The purpose of current study is to determine the clinical efficacy and tolerability of combination therapy of Dasatinib with multi-agent chemotherapy in newly-diagnosed Ph+ ALL.
详细描述
In this single-center, open-label, Phase II study, nonrandomized,no control,prospective clinical trial,a total of 30 Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ALL) patients will be enrolled.Patients will be diagnosed according to morphologic,immunologic, cytogenetic and molecular(MICM) criteria, including bone marrow morphology, immunophenotype, cytogenetic and molecular genetic (BCR/ABL gene, qualitative and quantitative analysis) examination.
Dasatinib 100 mg per day will be given orally along with combination chemotherapy starting day 8 of induction chemotherapy. Dasatinib will be given continuously (if it's tolerable) for 2 years since achievement of complete remission (CR) as part of consolidation chemotherapy and maintenance therapy.Patients can receive allogeneic hematopoietic stem cell transplantation (HSCT),or patients who keep BCR/ABL negative can receive autologous HSCT whenever possible during their first CR. Otherwise, they will finish the consolidation chemotherapy. Total duration of follow-up will be 2 year after last enrollment.
Pre-treatment evaluation will include complete blood count (CBC) with reticulocyte count, chemistry, electrolytes, coagulation, hepatitis profile, chest X-ray.Evaluation during treatment will include: CBC every two days during myelosuppression, chemistry, electrolytes, coagulation before each cycles of chemotherapy. Quantitative PCR (RQ-PCR) for Bcr-Abl will be done from bone marrow mononuclear cells at diagnosis, at CR, and before each cycles of consolidation chemotherapy,then every 3 months during maintenance therapy. For patients who undergo allogeneic HSCT, quantitative PCR for Bcr-Abl will be done from bone marrow mononuclear cells at the initiation of conditioning, and then every 3 months. PCR will be done in IS standardized lab.
Side effects of combination therapy will be monitored and described according to Common Toxicity Criteria, version 4.0 (National Cancer Institute, USA).
The purpose of current study is to determine the clinical efficacy and tolerability of combination therapy of Dasatinib with multi-agent chemotherapy in newly-diagnosed Ph+ ALL.
