TAK-733 is a potent, selective, non ATP-competitive MEK inhibitor with IC50 of 3.2 nM.
Targets
MEK1/2
IC50
3.2 nM [1]
In Vitro
TAK-733 is highly potent and selective MEK allosteric site inhibitor with IC50 of 3.2 nM. TAK-733 shows potent enzymatic and cell activity with an EC50 of 1.9 nM against ERK phosphorylation in cells. [1]
In Vivo
TAK-733 demonstrates broad antitumor activity in mouse xenograft models of human cancer including models of melanoma, colorectal, NSCLC, pancreatic and breast cancer. TAK-733 is well tolerated with pharmacokinetics and pharmacodynamics that support once-daily oral dosing in humans. [1] TAK-733 shows maximally efficacious doses at once daily orally doses of 10 mg/kg. [2]
Clinical Trials
A Multicenter, Open-label, Dose-escalation, Phase I Study of TAK-733, an Oral MEK Inhibitor, in Adult Patients With Advanced Nonhematologic Malignancies.
Features
Combination Therapy
Description
Alisertib at dose of 30 mg/kg combine with TAK-733 at dose of 10 mg/kg result in additive to synergistic antitumor activity and in prolonged inhibition of tumor regrowth in experimental human solid tumor xenograft models including NSCLC (NCI H23 [KRAS and LKB1 mutations]), CRC (SW620 [KRAS, APC, p53 mutations]), and pancreatic cancer (Panc 1 and Capan 1 [KRAS mutations] and BxPC-3 [No MAPK mutations]) models in immunocompromised mice.
