Background

MEK162 (ARRY-162, ARRY-438162) is a novel, selective inhibitor of MEK 1/2 with IC50 of about 12 nM [1].

Co-treatment of MEK162 and PKC inhibitors persistently inhibited MAP-kinase pathway. The co-treatment can halt proliferation and induce apoptosis of uveal melanoma cells even with GNAQ or GNA11 mutations [2]. All N-RAS mutant melanoma cells were sensitive to MEK 162. MEK162 reduced ERK1/2 phosphorylation, clonogenic survival, and induced apoptosis [3].

Phase Ib or II clinical trials were conducted in 32 cutaneous melanoma patients. 20 patients in MEK162 monotherapy and 12 on MEK162 plus RAF inhibitor or selective BRAF inhibitor combination therapy underwent ophthalmological examinations and multimodal imaging. These therapy all induced transient retinopathy with multiple bilateral lesions in some patients. The effect of MEK162 in retinopathy has been usually mild, self-limiting, and tolerable [4].
