The Efficacy and Safety of Anlotinib in Patients With Metastatic Pheochromocytoma or Paraganglioma

• Status: Not yet recruiting
• Trial end date: 2023-10-17
• Target enrollment: 0
• Participant gender: All

Summary

This phase II trial studies how well anlotinib hydrochloride works in treating patients with metastatic pheochromocytoma or paraganglioma. Anlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.

• Phase: Phase 2
• Accepts Healthy Volunteers?: Accepts Healthy Volunteers

• Active or uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements

• Receiving any other investigational agent

• Current use of warfarin for any reason; NOTE: if patient can be safely transitioned to another anticoagulant, they may be eligible provided other criteria are satisfied
