MEK inhibitor market is a type of drug that specifically targets and inhibits the MEK enzymes, which is crucial for MAPK signaling pathway. MEK inhibitors are used in the treatment of cancer, by blocking MEK activity, which prevent the growth of cancer cells. These drugs are commonly used in the treatment of certain cancers, such as melanoma, non-small cell lung cancer (NSCLC), and colorectal cancer, especially where there are mutations in the BRAF gene. MEK inhibitors are often used in combination with other targeted therapies, such as BRAF inhibitors, to improve treatment efficacy and delay the development of resistance, is responsible to growth of MRK inhibitor market share.

Key Highlights
In February 2021, Merck KGaA, got approval for two oral MEK inhibitors to Day One Biopharmaceuticals. This collaboration was aimed to allow Day One to test pimasertib in combination with its pan-RAF kinase inhibitor, to expand its potential application in solid tumors. Merck initiated a series of studies to assess the molecule as both a single agent and in combination therapy in multiple cancers. Merck took another MEK1/2 inhibitor, MSC2015103B, into the clinic to target this pathway for therapeutic benefit.
Report Analysis:
Reactivation of MAPK Pathway:
Mitogen-activated protein kinase (MAPK) pathway inhibitors, such as MEK inhibitors, are utilized in cancer therapy to suppress tumor growth by targeting key components of the MAPK signaling cascade. Mutations in upstream kinases such as RAF and RAS can reactivate the MAPK pathway despite MEKi treatment, contributing to resistance. MEKi can lead to the upregulation of RTKs such as EGFR, ERBB3, IGF-1R, and PDGFR. This reactivation occurs due to ERK1/2, characteristically repressed by MEK, is suppressed during MEKi treatment, leading to the disinhibition of these RTKs. The reactivated RTKs can initiate alternative signaling pathways that promote cell survival and proliferation, thereby contributing to adaptive resistance.
