About this study

Official title: A Phase I 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.

Read the detailed description

This was originally designed as a phase 1/2 study. The phase 1 patients received a small dose of study drug to see if the tumors absorb the drug. If the patient's tumors absorbed the drug, then the patient received one therapeutic dose. In the phase 1 portion, the study employed a 3 + 3 dose escalation design. Enrollment in the phase 1 portion was to be completed once researches believed that they found the highest dose that they could give patients without causing unacceptable toxicity. This dose is called the maximum tolerated dose (MTD). Following discussions with the Food and Drug Administration (FDA) that occurred during the dose escalation stage of the study, the protocol was amended to conclude the trial upon the identification of the MTD. The Phase 2 safety/ efficacy stage of the study was conducted with modifications of the primary endpoint as Protocol MIP IB12B, with Special Protocol Assessment Agreement with the FDA in March 2009.

Study groups in NCT00458952
Study groupRoleWhat they receive
Dose EscalationExperimentalDosing of Ultratrace iobenguane I 131 began at 6.0 mCi/kg and escalated in 1.0 mCi/kg increments in order to establish the MTD. 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. MTD of Ultratrace Iobenguane I 131

    Although no primary efficacy endpoint was defined for this study, the MTD of Ultratrace iobenguane I 131 in patients with malignant pheochromocytoma/paraganglioma (a safety rather than an efficacy parameter) is the primary objective.

    Measured: 6 weeks post therapy dose

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Ultratrace Iobenguane (MIBG) I 131 in people with Pheochromocytoma and Paraganglioma, run by Molecular Insight Pharmaceuticals, Inc. at 3 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Jul 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 20 Apr 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

MTD of Ultratrace Iobenguane I 131 (time frame: 6 weeks post therapy dose). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00458952, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jul 2016.
