This phase 2 single-arm study aims to demonstrate the efficacy of strong cytochrome inhibition with ketoconazole to reduce dasatinib dosage for adults with chronic myelogenous leukemia. Researchers will describe response rates and adverse events.

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 B is a phase I/II trial evaluating the safety and efficacy of dasatinib + venetocolax in combination with dexamethasone + Cyclophosphamide and cytarabine in children and AYA with R/R ped ALL/LBL whose tumor present with alterations in the MAPK/SRC pathway.

This phase III trial compares the effect of the combination of blinatumomab with dasatinib and standard chemotherapy versus dasatinib and standard chemotherapy for treating patients with Philadelphia chromosome positive (PH+) or Philadelphia chromosome-like (Ph-Like) ABL-class B-Cell acute lymphoblastic leukemia (B-ALL). Blinatumomab is a bispecific antibody that binds to two different proteins-one on the surface of cancer cells and one on the surface of cells in the immune system. An antibody is a protein made by the immune system to help fight infections and other harmful processes/cells/molecules. Blinatumomab may bind to the cancer cell and a T cell (which plays a key role in the immune system's fighting response) at the same time. Blinatumomab may strengthen the immune system's ability to fight cancer cells by activating the body's own immune cells to destroy the tumor. Dasatinib is in a class of medications called tyrosine kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply, which may help keep cancer cells from growing. Giving blinatumomab and dasatinib in combination with standard chemotherapy may work better in treating patients with PH+ or Ph-Like ABL-class B-ALL compared to dasatinib and chemotherapy alone.
