Zotiraciclib (TG02) is a potent oral spectrum selective[clarification needed][2] kinase inhibitor for the treatment of cancer. It was discovered in Singapore by S*BIO Pte Ltd and falls under the category of small molecule macrocycles. It crosses the blood brain barrier and acts by depleting Myc through the inhibition of cyclin-dependent kinase 9 (CDK9).[3] It is one of a number of CDK inhibitors under investigation; others targeting CDK9 for the treatment of acute myeloid leukemia include alvocidib and atuveciclib.[4][5] Myc overexpression is a known factor in many cancers, with 80 percent of glioblastomas characterized by this property.[6] Zotiraciclib has been granted orphan drug designation by the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the treatment of gliomas.[7][8]
As of January 2020[update], zotiraciclib is being evaluated by Adastra Pharmaceuticals in two separate Phase 1b clinical trials for the treatment of glioblastoma multiforme (GBM). Zotiracicib is also being developed as a potential treatment for diffuse intrinsic pontine glioma (DIPG), a rare pediatric cancer. Both forms of brain cancer are characterized by Myc overexpression.[6]
