A study of DHP107, a novel oral paclitaxel formulation, to determine maximum tolerated dose and recommended dose for phase II trial in patients with advanced solid cancer and explore efficacy of DHP107 in patients with gastric cancer

1. Primary objective To determine the maximum tolerated dose and the recommended dose for phase 2 clinical trial for the repeated administration of DHP107 (oral paclitaxel) on advanced solid cancer patients

2. Secondary objectives

   • To identify the dose limiting toxicity and the safety (toxicity) of DHP107
   • To evaluate the efficacy (tumor response rate) of DHP107
   • To assess pharmacokinetic (PK) characteristics of DHP107

Inclusion Criteria:

1. Patients between 18 and 70 years old
2. Patients prognosed with advanced or metastatic solid cancer by histopathology or cytology analysis who have no available standard therapy or who have failed at least once with the standard therapy
3. Adequate bone marrow function, liver function and adequate kidney function
4. Eastern Cooperative Oncology Group performance status ≤ 2
5. Life expectancy of 3 month or more
6. Written informed consent

5. Patients who are required to continuously take P-gp (P-glycoprotein) suppressor, immune suppressor, proton-pump inhibitor or H2-receptor antagonist during clinical trial period
