Arms and Interventions

Arm

Intervention/treatment

Experimental: Dose escalaltion study of HH2710; to determin the MTD of HH2710 and/or Recommended Phase II dose (RP2D).

Drug: HH2710; HH2710 is a small molecule that potently inhibits both ERK1 and ERK2 protein kinases in the nanomolar range. The kinase selectivity assessment towards a panel of over 400 protein kinases showed that HH2710 barely inhibited other kinases at a concentration up to 1 μM, except the substantial inhibition against ERK1 (MAPK1), ERK2 (MAPK2) and the MAPK pathway upstream kinases MEK and RAF proteins.
