The purpose of this study is to determine the safety and tolerability of three dose levels of combretastatin A4 phosphate (CA4P) given intravenously (IV) in combination with bevacizumab every 14 days in patients with advanced solid tumors. The maximum tolerated dose will be defined if it is at one of the three dose levels under study.
Drug: Combretastatin A4 Phosphate (CA4P)
Drug: Bevacizumab (Avastin)
Endpoint Classification: Safety Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
||OXC4P1-105: A Phase I Study of the Safety, Tolerability, and Antitumor Activity of Escalating Doses of Combretastatin A4 Phosphate Given in Combination With Bevacizumab to Subjects With Advanced Solid Tumors
Primary Outcome Measures:
- safety and tolerability of the combination therapy assessed by analysis of adverse events
- safety and tolerability of the combination therapy assessed by analysis of laboratory tests
