Trial of Cabozantinib (XL184) in Castrate-Resistant Prostate Cancer Metastatic to Bone

Stopped early · Phase 2

Conditions studied: Prostate Cancer Metastatic

In brief

The purpose of this study is to look at the effects of cabozantinib on castrate-resistant prostate cancer metastatic (cancer that has spread to other parts of the body) to the bone and to learn about any side effects caused by taking cabozantinib.

• Participant must have discontinued antiandrogen therapy at least 4 weeks (for flutamide and megestrol acetate) or 6 weeks (for bicalutamide or nilutamide) prior to the first dose of XL184. Participants currently on LHRH or GnRH agonists can be maintained on these agents.

• No radiation therapy within 14 days of study treatment. No radionuclide treatment within two months.
• No known brain metastases.
• Test results that measure how quickly blood clots need to be adequate for the study
• Participants who require concomitant treatment, in therapeutic doses, with anticoagulants such as warfarin or warfarin-related agents, heparin, thrombin or Factor Xa inhibitors, or antiplatelet agents (e.g., clopidogrel). Low dose aspirin (≤ 81 mg/day), low-dose warfarin (≤ 1 mg/day), and prophylactic low molecular weight heparin (LMWH) are permitted.
• Participants must not have uncontrolled significant illness including but not limited to: ongoing or active infection requiring systemic treatment, symptomatic congestive heart failure, uncontrolled hypertension , history of hypertensive emergency (e.g.encephalopathy) or hypertensive urgency within 6 months of study treatment, clinically significant wounds including osteonecrosis, history of organ transplant, unstable angina pectoris, stroke within 3 months of study drug, heart attack within 3 months of study drug, development of clots within blood vessels within 6 months of study drug, bleeding from distended veins within 3 months of study drug, any other severe or life threatening hemorrhage/bleeding, major surgery within 4 weeks of study treatment, clinically significant cardiac arrhythmias, history of bowel obstruction within 6 months of study drug or unresolved malabsorption syndrome, untreated bone fracture including tumor-related pathologic fracture, anticipated need for major surgery during the period of the study.
• Corrected QT interval, as measured by an ECG, must be within acceptable protocol limits within 28 days of entering the study
• Unable to swallow capsules
