Description: Zotiraciclib, also known as TG02 and SB1317, is a novel small molecule potent CDK/JAK2/FLT3 inhibitor. Zotiraciclib may be useful for the treatment of cancer that crosses the blood brain barrier and acts by depleting Myc through the inhibition of cyclin-dependent kinase 9 (CDK9). 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. Myc overexpression is a known factor in many cancers, with 80 percent of glioblastomas characterized by this property.

Additional Information

TG02 was shown to be a 10-50nM inhibitor of CDKs 1,2,7 and 9 and other ongogenic kinases, including FLT3, JAK2 and ERK5. TG02 potently inhibits proliferation across a broad panel of human solid tumor cell lines (n = 15, IC50 from 64 to 504 nM). This potency exceeded that of other pan-CDK inhibitors currently in clinical development (SNS-032 and seliciclib) and other drugs that block FLT3 and JAK2 but lack CDK activity (sunitinib and TG101348), suggesting that the unique spectrum of kinases inhibited by TG02 may provide enhanced antitumor activity in solid tumors. TG02 potently induced G2/M cell cycle arrest that rapidly progressed to robust apoptosis in HCT116 cells and synergized with doxorubicin in pancreatic and breast cancer cell lines and with gemcitabine in ovarian carcinoma cells. TG02 was cleared from the blood within 8 hours of PO dosing but was retained in tumor masses at supratherapeutic levels for 24-48 h, depending on dose. Accordingly, pathway-related biomarkers were markedly suppressed for 24-72 h after dosing. In mice bearing SC HCT116 xenografts, TG02 inhibited tumor growth by 82% (p<0.001) at 75 mg/kg PO Q2D. Conclusions: TG02 is a multi-kinase inhibitor with a previously unreported spectrum of targets that shows promising preclinical activity for the treatment of solid tumors in man.
