Non-hematologic Malignancies, Pharmacokinetics of ASP9853
Conditions
Keywords
ASP9853, Docetaxel, Paclitaxel
Brief summary
The purpose of this study is to determine the safety and tolerability and pharmacokinetics of ASP9853 combined with docetaxel or with paclitaxel in subjects with advanced non-hematologic malignancies.
Detailed description
This is a two part study. Part 1 will test increasing dose levels of ASP9853 in combination with docetaxel. Part 2 will test increasing doses of ASP9853 combined with paclitaxel. Each part will determine the maximum tolerated dose and recommended Phase 2 dose for ASP9853 in combination with each taxane. Preliminary evidence of antitumor activity of ASP9853 in combination with docetaxel or with paclitaxel also will be explored.
