About this study

Official title: Evaluation of Biodistribution, Dosimetry, Diagnostic Ability, and Safety of Al18F-NOTA-LM3 in Patients With Well-differentiated Neuroendocrine Tumors, and Comparison With 68Ga-DOTATATE and 68Ga-NODAGA-LM3: A Prospective, Single-center, Double-blinded Study

This prospective, single-center, double-blinded study investigates the biodistribution, dosimetry, safety, and diagnostic ability of Al18F-NOTA-LM3 in patients with well-differentiated neuroendocrine tumors. And compares the diagnostic ability of Al18F-NOTA-LM3 with 68Ga-DOTATATE PET/CT and 68Ga-NODAGA-LM3 PET/CT. Clinical management will also be compared using different imaging modalities.

Read the detailed description

Somatostatin receptors (SSTR), especially SSTR subtype 2 (SSTR2), are highly expressed in well-differentiated neuroendocrine tumors (NETs). Radiolabeled somatostatin analogs, including 68Ga-DOTATATE, are widely used for NET imaging and play essential roles in primary tumor seeking, staging, as well as management. SSTR antagonists have recently emerged as another type of somatostatin analog and showed better performance than analogs. Our previous studies exhibited better diagnostic efficacy of 68Ga-DOTA-LM3, 68Ga-DOTA-JR11, and 68Ga-NODAGA-LM3 compared to 68Ga-DOTATATE, especially liver metastasis.

18F-labeled radiotracers have shown several advantages compared to 68Ga-labelled tracers, including increased cyclotron production, lower positron energy, and longer half-life when compared to 68Ga, theoretically to the benefit of image quality. The purpose of this study is to investigate the biodistribution, safety, and diagnostic ability of Al18F-NOTA-LM3 in patients with well-differentiated neuroendocrine tumors. And compare the diagnostic ability of Al18F-NOTA-LM3 with 68Ga-DOTATATE PET/CT and 68Ga-NODAGA-LM3 PET/CT. Clinical management related to imaging will also be compared.

Patients with histologically confirmed well-differentiated neuroendocrine tumors (G1 and G2) will be recruited in this study. All patients will be randomized into two arms (A and B): Patients in arm A performed Al18F-NOTA-LM3 and 68Ga-DOTATATE. Patients in arm B performed Al18F-NOTA-LM3 and 68Ga-NODAGA-LM3. The first eight patients will undergo serial PET scans at 5, 15, 30, 45, 60, and 120 min after injection of Al18F-NOTA-LM3. The following patients will perform a whole-body PET/CT scan at 60-90 minutes after injection of Al18F-NOTA-LM3. All patients a whole-body PET/CT scan at 40-60 minutes after administering 68Ga-DOTATATE or 68Ga-NODAGA-LM3. For each patient, the two pet scans should be done within a week and the interval between the two scans should be at least 24h in case of mutual interference.

The images were reviewed by 2 experienced nuclear medicine physicians who were masked to all patients' clinical information. The results were based on consensus, with any discrepant result resolved by a consensus image interpretation by a third senior physician.

The biodistribution, dosimetry, safety, and diagnostic ability of Al18F-NOTA-LM3 will be explored. The diagnostic ability of Al18F-NOTA-LM3 with 68Ga-DOTATATE PET/CT and 68Ga-NODAGA-LM3 PET/CT will be compared. We will also compare the clinical management using different imaging modalities.

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 5 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: status not confirmed, as of the sponsor's last update on 2 Apr 2025. 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 China. 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?

Results are not available in the source record.

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

Contact Meixi Liu, MD (+86-15010405355, meixiliu_pumc@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety of Al18F-NOTA-LM3 (time frame: From radiotracer injection to 24 hours post-injection.). The study lists 7 primary outcomes in all. 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 NCT06056362, which also lists 2 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 2 Apr 2025.
