Phase I Study to Determine the Maximum Tolerated Dose and to Assess the Safety and Pharmacokinetic Profile of HM781-36B in Patients With Advanced Solid Tumors

Study Overview
=================
Brief Summary
-----------------
The main objective of this study is to determine the maximum tolerated dose (MTD) of HM781-36B.

Detailed Description
-----------------
Besides the main objective, there are 3 other objectives as follows: To determine dose-limiting toxicity (DLT) of HM781-36B To characterize the pharmacokinetics of HM781-36B, following oral administration of HM781-36B To evaluate anticancer activity of HM781-36B in patients with advanced solid malignancies Groups of 3 patients per cohort or dose level will be treated with escalating doses of HM781-36B

Subjects who cannot be followed up regularly due to psychological, social, family, logistic, and geographical reasons 9) Subjects who were administered with other investigational products within 30 days before screening. 10) Subjects who, in the investigator's opinion, cannot be participated.
