HEM-iSMART is a master protocol with sub-protocols. The overarching objective is that introducing targeted therapy using a biomarker driven approach for treatment stratification may improve the outcome of children with R/R acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL) It is characterized by a shared framework that allows for the investigation of multiple IMPs and generate pivotal safety and efficacy evidence within the sub-protocols to establish and define the benefits and risks of new treatments for children with R/R leukemia.~Sub-Protocol D within HEM-iSMART, is a phase I/II, multicenter, international, open-label clinical trial designed to evaluate the safety, tolerability, pharmacokinetics (PK) and efficacy of trametinib in combination with dexamethasone, cyclophosphamide and cytarabine in children, adolescents and young with R/R ALL and LBL. Patients with actionable alterations in the RAS-RAF-MAPK pathway will be eligible for sub-protocol D including but not limited to KRAS, NRAS, HRAS, FLT3, PTPN11, MAP2K1, MP2K1 hotspot mutations, cCBL; NF1 del.
HEM-iSMART is a master protocol which investigates multiple investigational medicinal products in children, adolescents and young adults (AYA) with relapsed/refractory (R/R) ALL and LBL. Sub-protocol D is a phase I/II trial evaluating the safety and efficacy of trametinib in combination with dexamethasone, cyclophosphamide and cytarabine in children and AYA with R/R ped ALL/LBL whose tumor present with alterations in the RAS-RAF-MAPK pathway.
