Phase 1-2 Study of Iobenguane (MIBG) I 131 in Patients With Malignant Pheochromocytoma/Paraganglioma
A Phase I-II Study Evaluating the Maximum Tolerated Dose, Dosimetry, Safety, and Efficacy of Ultratrace Iobenguane I 131 in Patients With Malignant Pheochromocytoma/Paraganglioma

The purpose of this study is to determine whether iobenguane I 131 is safe and effective in patients with malignant pheochromocytoma or paraganglioma.

This is a phase 1 and phase 2 study. The phase 1 patients will be enrolled before the phase 2 patients are enrolled. Each patient will receive a small dose to see if the tumors absorb the drug. If the patient's tumors absorb the drug, then the patient will receive one therapeutic dose. In the phase 1 portion, every 3 patients will be given the same therapeutic dose, and usually each group of 3 patients will be given a larger dose than people who were enrolled before them. Enrollment in the phase 1 portion will be complete once researches believe that they have found the highest dose that they can give patients without causing unacceptable toxicity. This dose is called the maximum tolerated dose (MTD). All phase 2 patients will receive the MTD. Each patient in phase 1 and phase 2 will be followed for 5 years following their therapeutic dose. During this 5-year follow-up period, patients will undergo tests such as 1.) CT or MRI scans and blood and urine tests to determine if the tumors shrink, grow, or stay the same; 2.) bone scans to see if the tumor has spread to or increased in the bones and, 3.) a quality of life test to see how the symptoms of pheochromocytoma or paraganglioma affect patients' daily lives.

Phase 1
Phase 2
Allocation: Non-Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
  • Pheochromocytoma
  • Paraganglioma
Drug: Ultratrace Iobenguane (MIBG) I 131
Phase I: Dose escalation protocol Phase II: Treatment schedule at therapeutic dose
Experimental: Dose Escalation
Dosing will begin at 6.0 mCi/kg and will escalate in 1.0 mCi/kg increments until the MTD is established. The MTD is the dose immediately below the level at which escalation stops due to dose-limiting toxicity (DLT). An additional 3 patients are to be treated at the MTD, for a total of 6.
Intervention: Drug: Ultratrace Iobenguane (MIBG) I 131
