Pheochromocytoma clinical trials at University of California Health
3 in progress, 1 open to eligible people
open to eligible people ages 18 years and up
Pheochromocytoma is a rare, catecholamine (ex. adrenaline) secreting tumor that requires preoperative alpha blockade to minimize intraoperative hemodynamic instability, thereby reducing intra- and postoperative morbidity and mortality. Phenoxybenzamine is a non-selective alpha blocker that is significantly more expensive and is associated with increased adverse effects in comparison with selective alpha blockers such as doxazosin. Retrospective studies show minimal differences in hemodynamic instability and no differences in postoperative morbidity and mortality between selective vs. non-selective alpha blockers. This study is a randomized controlled trial that will compare hemodynamic instability, morbidity, mortality, cost, and quality of life between patients blocked with phenoxybenzamine vs. doxazosin.
A Study Evaluating Ultratrace Iobenguane I131 in Patients With Malignant Relapsed/Refractory Pheochromocytoma/Paraganglioma
Sorry, in progress, not accepting new patients
This clinical trial is designed to evaluate the effectiveness and collect additional safety information on AZEDRA® (iobenguane I 131) for the treatment of metastatic or relapsed/refractory (to other treatment) or unresectable pheochromocytoma or paraganglioma. The purpose of this trial is to test the use of AZEDRA® as a treatment for pheochromocytoma and paraganglioma, a rare disease. This Phase II study will help determine primarily if using the drug reduces the amount of blood pressure medication being taken as a result of the cancer and secondarily to determine such things as the effectiveness of the study drug in treating the cancer, additional safety measures, and to assess if the drug helps the quality of life and use of pain medication. All subjects will receive an imaging dose with scans followed by two therapeutic doses given approximately 3 months apart.
Sorry, not accepting new patients
This is a compassionate use protocol to allow palliative therapy for patients with malignant pheochromocytoma and paragangliomas.
