Descriptive Information
Brief Title  ICMJE Study of XL999 in Patients With Metastatic Colorectal Cancer
Official Title  ICMJE A Phase 2 Study of XL999 Administered Intravenously to Subjects With Metastatic Colorectal Cancer
Brief Summary This clinical study is being conducted at multiple sites to determine the activity, safety, and tolerability of XL999 when given weekly to patients with metastatic colorectal cancer (CRC). XL999 is a small molecule inhibitor of multiple kinases including VEGFR, PDGFR, FGFR, FLT-3, and Src, which are involved in tumor cell growth, formation of new blood vessels (angiogenesis), and metastasis.
Detailed Description Not Provided
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 2
Study Design  ICMJE Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE Colorectal Cancer
Intervention  ICMJE Drug: XL999
XL999 will be administered at 2.4 mg/kg as a 4-hour intravenous (IV) infusion. Subjects will receive XL999 infusions weekly for 8 weeks of treatment unless drug-related toxicity requires dosing delay. In the absence of progressive disease and unacceptable toxicity, subjects may receive XL999 treatment weekly for up to a year on this study. After 8 weeks, at the discretion of the investigator, one dose of four may be omitted for a subject's convenience.
