The mammalian target of rapamycin (mTOR) pathway is critical for tumor development, and mTOR inhibitors have revealed modest results.
In vitro: CC-223 was identified as an ATP–competitive inhibitor of the mTOR kinase targeting mTORC1 of both 4EBP1 and p70 S6 kinase 1 and mTORC2, which prevented the upregulation of AKT phosphorylation. Moreover, CC-223 was selectively potent to mTOR kinase while showed more than 150-fold sensitivity against the related lipid kinase, PI3Ka. In addition, CC-223 was active over many non-Hodgkin lymphoma cell lines and solid tumor lines such as including glioma, breast, hepatocellular carcinoma, as well as non–small cell lung cancer [1].
In vivo: In animal study, CC-223 was selected for evaluation in PC-3 tumor bearing efficacy mouse models. Mice were orally treated with vehicle or various doses of CC-223 once daily or twice daily at a dose of 5 mL/kg for 21 days, and the final reductions of tumor volume were measured following the final day of dosing. Results showed that All CC-223 had dose- and schedule-dependent inhibition of tumor growth in the PC-3 model. Moreover, the maximum observed efficacy for CC-223 was determined to be 87%, at its tolerated dose of 25 mg/kg q.d. [1].
Clinical trial: In previous clinical study, CC-223 was found to be tolerable with manageable toxicities. In addition, the preliminary antitumor activity, such as tumor regression and evidence of mTORC1/mTORC2 pathway inhibition were also observed [2].
