Inotuzumab ozogamicin is an antibody-drug conjugate using linker and cytotoxic drug technology similar to that developed for the ground-breaking treatment Mylotarg (), which was approved by the US FDA in 2000 for the treatment of acute myeloid leukaemia. Inotuzumab ozogamicin consists of a recombinant humanised IgG4 kappa CD22-targeting monoclonal antibody covalently attached to calicheamicin derivative, N-acetyl-gamma-calicheamicin dimethylhydrazide, which is a potent DNA-binding cytotoxic agent. Developed by Pfizer and UCB, inotuzumab ozogamicin was granted approval by EU in June 2017 followed by FDA on August 17th, 2017 for the treatment of adults with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL). ALL is a rapidly progressing cancer of the bone marrow that is associated with
Selpercatinib is a kinase inhibitor with enhanced specificity for RET tyrosine kinase receptors (RTKs) over other RTK classes.[A202055, A202052, L13604] Enhanced RET (Rearranged during transfection) oncogene expression is a hallmark of many cancers. Although multikinase inhibitors, including [cabozantinib], [ponatinib], [sorafenib], [sunitinib], and [vandetanib], have shown efficacy in RET-driven cancers, their lack of specificity is generally associated with substantial toxicity. Selpercatinib (LOXO-292) and pralsetinib (BLU-667) represent the first generation of specific RET RTK inhibitors for the treatment of RET-driven cancers.[A202049, A202055, A202052, L13604] Although selpercatinib is currently still under investigation in clinical trial NCT04211337, it was granted accelerated FDA approval on May 8, 2020, for specific RET-driven cancer indications. It is currently marketed under the brand name RETEVMO™ by Loxo Oncology Inc. Selpercatinib is also approved by the European Commission.
