Condition(s) targeted: Pheochromocytoma; Paraganglioma

Intervention: Ultratrace Iobenguane (MIBG) I 131 (Drug)

Phase: Phase 1/Phase 2

Status: Active, not recruiting

Sponsored by: Molecular Insight Pharmaceuticals, Inc.

Official(s) and/or principal investigator(s):
Norman LaFrance, MD, Study Director, Affiliation: Molecular Insight Pharmaceuticals

Summary

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

Clinical Details

Official title: 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

Study design: Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome:

Phase1: toxicities (DLTs) in 1st 6 weeks after therapeutic (tx) dose

Phase2: tumor response by CT/MRI 9 months after tx dose

Secondary outcome:

Phase1: radiation absorbed 1 hour after dose 1(small dose), 2-4 days after dose 1, and 5-7 days after dose 1; tumor response by CT/MRI & blood/urine tests 3, 6, 9, & 12 months after tx dose; dose response by CT/MRI 9 months after tx dose

Phase2: tumor response by CT/MRI & blood/urine tests 3, 6, 9, & 12 month after tx dose; quality of life 3, 6, 9, & 12 months after tx dose

Detailed description: 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.
