Assess the Safety and Activity of Combined MG005 and Sorafenib (NEXAVAR®) Treatment With Solid Tumor

"Phase I:~Eligible patients will receive different dosages of GW5074 in 1 of the 3 dose cohorts plus 200 mg of sorafenib. Dose cohorts will be escalated sequentially from Cohort 1 at 750 mg QD GW5074 plus 200 mg QD sorafenib to Cohort 2 at 1500 mg QD GW5074 plus 200 mg QD sorafenib, and Cohort 3 at 750 mg BID GW5074 plus 200 mg QD sorafenib. Owing to the fact that there is no previous human experience for GW5074, Cohort 1 will include a monotherapy stage with 750 mg QD GW5074 prior to administration of the GW5074 and sorafenib combination to initially assess the safety of GW5074 monotherapy."
