About this study

Read the detailed description
Somatostatin receptor imaging with 68Ga-DOTATATE PET/CT (DOTATATE) is increasingly used for managing patients with neuroendocrine tumors. The objective of this study was to determine referring physicians' perspectives on the impact of DOTATATE on the management of neuroendocrine tumors. Methods: A set of 2 questionnaires (pre-PET and post-PET) was sent to the referring physicians of 100 consecutive patients with known or suspected neuroendocrine tumors, who were evaluated with DOTATATE. Questionnaires on 88 patients were returned (response rate, 88%). Referring physicians categorized the DOTATATE findings on the basis of the written PET reports as negative, positive, or equivocal for disease. The likelihood for metastatic disease was scored as low, moderate, or high. The intended management before and changes as a consequence of the PET study were indicated. Results: The indications for PET/CT were initial and subsequent treatment strategy assessments in 14% and 86% of patients, respectively. Referring physicians reported that DOTATATE led to a change in suspicion for metastatic disease in 21 patients (24%; increased and decreased suspicion in 9 [10%] and 12 [14%] patients, respectively). Intended management changes were reported in 53 of 88 (60%) patients. Twenty patients (23%) scheduled to undergo chemotherapy were switched to treatments without chemotherapy, and 6 (7%) were switched from watch-and-wait to other treatment strategies. Conversely, 5 patients (6%) were switched from their initial treatment strategy to watch-and-wait. Conclusion: This survey of referring physicians demonstrates a substantial impact of DOTATATE on the intended management of patients with neuroendocrine tumors.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
68Ga-DOTATATEDrug
Also called 68Ga-DOTATATE PET/CT scan
68Ga-DOTATATE will be given in tracer doses and injected intravenously to image Neuroendocrine tumors by Positron Emission Tomography.
| Study group | Role | What they receive |
|---|---|---|
| PET/CT with one-time administration of 68Ga-DOTATATE | Experimental | Study participants will receive a one-time administration of 68Ga-DOTATATE and undergo a PET/CT imaging study. Scans will be performed with oral and IV contrast. The physicians of patient's receiving a 68Ga-DOTATATE PET/CT will be asked to fill out 2 questionnaires with questions pertaining to the patient's medical management. One questionnaire will be sent before the scan, and one shortly after the scan was performed and the results reported to the referring physician. Receives: Drug: 68Ga-DOTATATE |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in intended management of patients with NETs after PET/CT
The study will collect questionnaire data from referring physicians on intended patient management before and after PET/CT.
Measured: Before the first scan and after the second scan and results reported

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing 68Ga-DOTATATE in people with Neuroendocrine Tumors, run by Jonsson Comprehensive Cancer Center at 1 site 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 5 inclusion and 6 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 19 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site 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 phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Change in intended management of patients with NETs after PET/CT (time frame: Before the first scan and after the second scan and results reported). 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 NCT01873248, which also lists 11 linked publications.
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 19 Jul 2024.
