  Purpose

This clinical trial is designed to evaluate the effectiveness and collect additional safety information on Ultratrace Iobenguane I 131 for the treatment of relapsed/refractory (to other treatment) malignant pheochromocytoma and paraganglioma.

The purpose of this trial is to test the use of Ultratrace iobenguane I 131 as a treatment for pheochromocytoma and paraganglioma type cancer. 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 therapy doses that are given 3 months apart.

Primary Outcome Measures:
  • Proportion of study subjects with a reduction (including discontinuation) of all antihypertensive medication by at least 50% for at least six months or two cycles Ultratrace Iobenguane I 131. [ Time Frame: 12 Months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Proportion of subjects with overall tumor response of Complete Response or Partial Response by RECIST criteria [ Time Frame: 24 Months ] [ Designated as safety issue: No ]
  • Safety assessed by changes in lab values, physical exams or vital signs, and the occurrence of treatment emergent adverse events [ Time Frame: 24 Months ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 75
Study Start Date: June 2009
Estimated Primary Completion Date: October 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Ultratrace Iobenguane I 131 Treatment Radiation: Ultratrace Iobenguane I131
Each subject will be administered 3 mCi to 6 mCi Ultratrace Iobenguane I 131, referred to as the Imaging Dose, to confirm that subject meets radiological entry criteria and to establish dosimetry. All subjects meeting entry criteria will then receive the investigational product referred to as the Therapeutic Dose (500 mCi or 8 mCi/kg if the subject weighs 62.5 kg or less) of Ultratrace Iobenguane I 131, followed by imaging at 7 days post infusion or upon discharge from isolation. The Therapeutic Doses will be adjusted equally if warranted by results of the dosimetry evaluation. At least 3 months later, subjects will receive the second Therapeutic Dose.
Other Name: Azedra

Detailed Description:

Azedra™ Ultratrace™ (Iobenguane I 131), commonly referred to as Ultratrace Iobenguane I 131, is a very high specific activity form of iobenguane I 131, produced using Molecular Insight's proprietary Ultratrace™ platform. Based on the well characterized cellular active transport mechanism, the higher the specific activity of iobenguane I 131, the greater the cellular uptake of radioactivity and hence greater tumor uptake.

During this study the subjects will receive two (2) Therapy Doses that are given three (3) months apart. Prior to administration of the first Therapy Dose, subjects will be given an Imaging Dose of Ultratrace Iobenguane I 131 and will undergo iobenguane I 131 scans to evaluate tumor uptake and to measure normal organ distribution and allow for the calculation of radiation dose to normal organs.

Screening procedures for eligibility will need to be done before imaging or therapeutic doses of Iobenguane I 131 are administered.

Hospitalization is required for approximately one (1) week after each of the two (2) Therapeutic Doses. Frequent follow up is necessary for the first year and some of the follow up visits may be done by a visiting health care professional in the subjects' homes. Subjects will be followed in the treatment study for one (1) year and for an additional four (4) years in long-term follow up.

  • Have a documented (medical record) diagnosis of either pheochromocytoma or paraganglioma with histological confirmation
  • Be ineligible for curative surgery for pheochromocytoma
  • Have failed a prior therapy for pheochromocytoma/paraganglioma or are not candidates for chemotherapy or other curative therapies
  • Be on stable antihypertensive medication for pheochromocytoma-related hypertension for at least 30 days
  • Have at least one tumor site by CT or MR or iobenguane I 131 scan
  • Have an expected survival of at least 6 months
  • Subjects must agree to use an acceptable form of birth control (abstinence, IUD, oral contraception, barrier and spermicide or hormonal implant) during this study and for 6 months following Therapeutic Doses of Ultratrace Iobenguane I 131.
  • Male subjects must agree not to father a child during the period beginning immediately after administration of the first Therapeutic Dose of Ultratrace Iobenguane I 131 during the study and ending six months after administration of the last Therapeutic Dose of Ultratrace Iobenguane I 131.

Exclusion Criteria:

Subjects will be excluded if any of the following conditions are observed:

  • <50% of FDG (if data are available) positive lesions are MIBG avid
  • Pregnant or nursing females
  • Active CNS lesions by CT/MR scanning within 3 months of study entry
  • New York Heart Association class IV heart failure, symptomatic congestive heart failure [New York Heart Association class IV with another medical disorder], unstable angina pectoris, cardiac arrhythmia
  • Received any previous systemic radiotherapy resulting in marrow toxicity within 3 months of study entry or have active malignancy (other than pheochromocytoma/paraganglioma) requiring additional treatment during the active phase or follow up period of the Ultratrace iobenguane I 131 trial.
  • Administered prior whole-body radiation therapy
  • Received external beam radiotherapy to > 25% of bone marrow
  • Administered prior chemotherapy within 30 days or have active malignancy (other than pheochromocytoma/ paraganglioma) requiring additional treatment during the active phase or follow up period of the Ultratrace iobenguane I 131 trial.
  • Karnofsky Performance Status is < 60
  • Platelets < 80,000/μL

  • Receiving a medication which inhibits tumor uptake of iobenguane I 131
  • Any medical condition or other circumstances (i.e., uncontrolled current illness including but not limited to, ongoing or active infection or psychiatric illness/social situations that would limit compliance with the study requirements.
  • Any other condition, that in the opinion of the investigator, may compromise the safety or compliance of the subject or would preclude the subject from successful completion of the study
