MedKoo CAT#: 200771

CAS#: 212631-79-3

Description: CI-1040, also known as PD184352, is a MEK inhibitor, which demonstrated in vivo activity in preclinical animal models and subsequently became the first MEK inhibitor to enter clinical trial. CI-1040 suffered however from poor exposure due to its poor solubility and rapid clearance, and as a result, development of the compound was terminated.

Additional Information

CI-1040 (PD184352) is an orally active, highly specific, small-molecule inhibitor of one of the key components of this pathway (MEK1/MEK2), and thereby effectively blocks the phosphorylation of ERK and continued signal transduction through this pathway. Antitumor activity has been seen in preclinical models with this compound, particularly for pancreas, colon, and breast cancers, which has been shown to correlate with its inhibition of pERK. Clinically, CI-1040 has been shown to be well tolerated in phase I studies, with safety and pharmacokinetic profiles that permit continuous daily dosing. Biomarker studies have shown target inhibition in patients, and antitumor activity has also been observed with a partial response in one patient with pancreatic cancer and stable disease in approximately 25% of phase I patients. Given the central role of the ERK/mitogen-activated protein kinase pathway in mediating growth-promoting signals for a diverse group of upstream stimuli, inhibitors of MEK, as a key central mediator, could have significant clinical benefit in the treatment of breast and other cancers.
 
However, in Phase II trials, CI-1040 demonstrated insufficient antitumor activity to warrant further development in the four tumors tested. PD 0325901, a second generation MEK inhibitor, has recently entered clinical development and, with significantly improved pharmacologic and pharmaceutical properties compared with CI-1040, it may better test the therapeutic potential of MEK inhibition in cancer.
