A Study to Evaluate a New Way to Identify/Diagnose Tumours With Somatostatin Receptors Using [68]Ga-HA-DOTATATE and to Ensure it is Safe to Use

• Status: Recruiting
• Trial end date: 2031-12-01
• Target enrollment: 0
• Participant gender: All

Summary

A [68]Ga-HA-DOTATATE PET/CT or PET/MRI scan is a nuclear medicine test used to create pictures of the whole body that will show where somatostatin receptors are found, including on tumours. Somatostatin receptors are found on most neuroendocrine tumours (NETs), and some other types of tumours. Currently at the Cross Cancer Institute, most patients with suspected somatostatin positive tumours (e.g. NETs) have an In-111 Octreotide (Octreoscan™) scan. A scientific study has shown that a scan with a similar product ([68]Ga-DOTATATE) is more accurate than an Octreoscan™. This study will look at [68]Ga-HA-DOTATATE, a product virtually identical to [68]Ga-DOTATATE.

The purpose of this study is to: 1) demonstrate the safety of [68]Ga-HA-DOTATATE; and 2) confirm that [68]Ga-HA-DOTATATE PET/CT or PET/MRI is effective at diagnosing somatostatin positive tumours.

Criteria

Inclusion Criteria:

1. Known or suspected somatostatin receptor positive tumour including, but not limited to, GNET, PNET, pulmonary NET, PRUNK NET, pheochromocytoma, paraganglioma, medullary thyroid cancer, and medulloblastoma. A standard CT or MRI obtained within 6 months of enrolment is required. Additional supporting evidence obtained within 12 months of enrolment may include: other standard imaging (In-111 octreotide (Octreoscan), [18]F-FDG PET, or [18]F-FDOPA PET); histopathology from surgery or biopsy; elevated biochemical markers (including Chromogranin A, 5-HIAA, insulin, vasoactive intestinal peptide (VIP), glucagon, gastrin, metanephrines, and/or others, as clinically indicated); and/or persistent carcinoid-like symptomology highly suspicious for the presence of NET even in absence of pathologic imaging findings by anatomic criteria;

2. Eastern Cooperative Oncology Group (ECOG) Performance Scale Score ≤ 3 within 2 weeks of enrolment;

3. At least 14 years of age;

4. Able and willing to follow instructions and comply with the protocol;

5. Ability to provide written informed consent prior to participation in the study.

Exclusion Criteria:

1. Inability to lie still for the entire imaging time (e.g. cough, severe arthritis, etc.);

2. Inability to complete the needed investigational and standard-of-care imaging examinations due to other reasons (severe claustrophobia, radiation phobia, etc.);

3. Any additional medical condition, serious inter-current illness or other extenuating circumstance that, in the opinion of the Investigator, may significantly interfere with study performance or interpretation;

4. Weight exceeding the PET/CT or PET/MR scanner limit;

5. Pregnancy;

6. Allergic reaction to DOTATATE or somatostatin analogues.
