Administration of GRASPA (Suspension of Erythrocytes Encapsulating L-asparaginase) in Elderly Patients With First Line Acute Lymphoblastic Leukemia
2021年9月21日 更新者:ERYtech Pharma
An Escalating Dose Phase IIa Study of L-Asparaginase Encapsulated in Erythrocytes (GRASPA®) in Association With Polychemotherapy During Induction Phase for Treatment of Elderly Patients With Acute Lymphoblastic Leukaemia (ALL), Aged 55 Years and Over, With Philadelphia Chromosome-negative (ALL Ph-)
The main purpose of this study is to determine the maximum tolerated and efficient dose of GRASPA® in combination with polychemotherapy treatment of elderly patients with ALL, 55 years and over, Philadelphia chromosome-negative (ALL Ph-).
調査の概要
詳細な説明
This open label, non randomised, multicentric and national phase IIa study was designed to evaluate the safety and efficacy of GRASPA®, a suspension of red blood cells encapsulating E. Coli L-asparaginase, at different doses and in combination with the polychemotherapy regimen recommended by the European Working Group on Adult ALL (EWALL) for frontline therapy of patients with ALL Ph-, aged 55 years old and over.
Patients with a good performance status (WHO score ≤2) and a newly diagnosed ALL Ph- were treated with the backbone polychemotherapy consisting of a first 4-week induction phase comprising dexamethasone, vincristine and idarubicin, a second 4-week induction phase including cyclophosphamide, cytarabine, a 6-month consolidation phase consisting of 6 alternating cycles with methotrexate, asparaginase and folinic acid (cycles 1, 3 and 5) and high-dose cytarabine (cycles 2, 4 and 6) with Granulocyte colony stimulating factor (G-CSF) support followed by a 16-month maintenance period with mercaptopurine, methotrexate and vincristine/dexamethasone pulses.
GRASPA® was administered on day 3 of induction 1 and on day 6 of induction 2 of the chemotherapy regimen.
