This trial will assess the safety and effectiveness of a new radioisotope for imaging tumors. The new radioisotope is produced at the Edmonton Radiopharmaceutical Centre.

Who is the study for?
This trial is for patients with suspected or confirmed somatostatin receptor positive tumors, such as certain neuroendocrine tumors. Participants must have had a CT or MRI within the last 6 months and be able to consent. It's not for those who've had allergic reactions to DOTATATE, weigh over 225 kg, can't lie still for imaging due to conditions like extreme claustrophobia, or lack intravenous access.Check my eligibility
What is being tested?
The study tests the safety and diagnostic effectiveness of a new imaging agent called 68Ga-HA-DOTATATE in detecting somatostatin receptor positive tumors using PET scans. This could potentially offer better image quality and accuracy compared to older methods.See study design
What are the potential side effects?
While specific side effects are not listed, potential risks may include allergic reactions similar to previous allergies to DOTATATE or related compounds. The procedure involves lying still during PET scanning which might cause discomfort.


Screening ~ 3 weeks
Treatment ~ Varies
Follow Up ~1 year post-scan
This trial's timeline: 3 weeks for screening, Varies for treatment, and 1 year post-scan for reporting.

Other Research
The most common treatments for Neuroendocrine Tumors (NETs) include somatostatin analogs, peptide receptor radionuclide therapy (PRRT), and molecular targeted therapies. Somatostatin analogs, such as octreotide and lanreotide, bind to somatostatin receptors on tumor cells, inhibiting hormone secretion and tumor growth. PRRT, like 177Lu-DOTATATE, combines a radioactive isotope with a somatostatin analog to deliver targeted radiation to the tumor cells, effectively killing them. Molecular targeted therapies, such as everolimus, inhibit pathways essential for tumor cell growth and survival. These targeted treatments are crucial for NET patients as they help manage symptoms, control tumor progression, and improve overall quality of life.
