Efficacy of Acute Lymphoblastic Leukemia-Based Therapy in Treating Patients With Acute Leukemia of Ambiguous Lineage

Recruiting now · Phase 2

Conditions studied: Acute Leukemia of Ambiguous Lineage

In brief

In this prospective, single arm, open label, clinical trial, a total of 50 acute leukemia of ambiguous lineage patients will be enrolled. Patients will receive acute lymphoblastic leukemia (ALL) -based chemotherapy and are permitted to receive allogeneic hematopoietic stem cell transplantation (HSCT) after CR . Otherwise, they will finish the consolidation chemotherapy. Patients with t(9;22) will receive chemotherapy combined with tyrosine kinase inhibitors. The purpose of current study is to evaluate the clinical efficacy of ALL-based chemotherapy，effect of genetic abnormality and minimal residual disease (MRD) on prognosis in patients with acute leukemia of ambiguous lineage.

You may qualify if…

Patients aged above 14 years with acute leukemia of ambiguous lineage .
Eastern Cooperative Oncology Group (ECOG) Performance status 2.
Adequate end organ function as defined by: Total bilirubin ≤ 1.5 x upper limit of normal (ULN); serum glutamic-oxaloacetic transaminase(SGOT) and serum glutamic pyruvic transaminase(SGPT) ≤ 2.5 x ULN; Creatinine ≤ 1.5 x ULN; Serum amylase and lipase ≤ 1.5 x ULN; Alkaline phosphatase ≤ 2.5 x ULN unless considered tumor related; Patients must have adequate cardiac function (ejection fraction ≥ 45 % on Multiple Gated Acquisition (MUGA) scan).
Patients must have the following laboratory values (≥ lower limit of normal (LLN) or corrected to within normal limits with supplements prior to the first dose of study medication.): Potassium ≥ LLN; Magnesium ≥ LLN; Phosphorus ≥ LLN
Patients should sign informed consent form.

You may not qualify if…

Impaired cardiac function:
Long QT syndrome or a known family history of long QT syndrome; clinically significant resting brachycardia (<50 beats per minute); ejection fraction < 45 % on MUGA scan. Corrected QT (QTc) interval > 450 msec on baseline ECG (using the QTcF formula). If QTcF interval>450 msec and electrolytes are not within normal ranges, electrolytes should be corrected and then the patient re-screened for QTc. Myocardial infarction within 12 months prior to starting study; other clinically significant heart disease (e.g. unstable angina, congestive heart failure or uncontrolled hypertension, uncontrolled arrhythmias).
Other concurrent severe and/or uncontrolled medical conditions:
Patients with another primary malignant disease, except those that do not currently require treatment; acute or chronic liver, pancreatic or severe renal disease; another severe and/or life-threatening medical disease.
Patients who are: (a) pregnant and (b) breast feeding.
