RESEARCH PLAN / BACKGROUND AND SIGNIFICANCE:

Tumors originating from the neuroendocrine system, although relatively rare, may be life threatening. In cases where the disease has metastasized, the 5 year survival is very poor. 131I meta-iodobenzylguanidine (MIBG)and 90Y DOTA-D-Phe1-Tyr3-Octreotide (DOTATOC) are two radiopharmaceuticals that have shown promise as therapeutic agents in patients with metastatic neuroendocrine tumors. However, delivering sufficient radiation dose to the tumor to obtain objective anti-tumor responses or cure with these radiopharmaceuticals is challenging because of the allowable dose limits imposed by radiation damage to normal tissues. Organ biodistribution and kinetics of 90Y DOTATOC and 131I MIBG are substantially different, which leads to different critical organs for these agents, the kidney for Y90Y DOTATOC and the red marrow for 131I MIBG. We propose to investigate a mechanism to increase the radiation dose delivered to tumors without exceeding "critical" radiation dose to normal organs by combining 90Y DOTATOC and 131I MIBG.

AIMS / OBJECTIVES:

The primary aim of this project is to determine, what fraction of individuals with neuroendocrine tumors would show substantially improved tumor dosimetry with combined agent therapy compared to "best" single agent therapy and determine the magnitude of the potential tumor radiation dose increase.

METHODS:

To achieve this, we plan to perform serial scintigraphic imaging procedures to measure patient specific bone marrow, kidney, and tumor biodistribution and kinetics for 111In Pentetreotide and 131I-MIBG in adults and children with neuroendocrine tumors. Then, using the program we have already developed, we will input the individual dosimetry measures for bone marrow, kidney and tumor to determine the optimal amounts of administered radioactivity for the combination of 131I MIBG plus 90Y DOTATOC or 131I MIBG alone.

What is being measured

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

  1. Dosimetry Results

    Determine the patient specific bone marrow, kidney and tumor dosimetry results for each subject from the 2 groups will be used to calculate the optimal combination of administered activities for 131I-MIBG plus 90Y-DOTATOC (group 1) 131I-MIBG plus 177Lu-DOTATATE (group 2) and the resultant dose delivery to tumor from each combination

    Measured: 1 week after scan

Secondary outcomes (1)
  1. Maximum Radiation Dose

    Calculate the optimal amount for either agent when administered individually along with corresponding tumor radiation dose to determine the amount of each product will give maximum tumor kill and not damage other vunerable organs..

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A study testing 131-I MIBG and 111-In pentetreotide and 131-I MIBG and In-111 DOTATATE in people with Neuroendocrine Tumors, run by David Bushnell at 2 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 4 inclusion and 7 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 21 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 2 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Dosimetry Results (time frame: 1 week after scan). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 21 Jul 2016.
