New imaging agent targets LRRC15 to sharpen cancer diagnosis

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: Each subject must meet all of the following inclusion criteria to be eligible for study enrollment: 1. The subject or their legally authorized representative (LAR) is capable of providing a signed and dated informed consent form (ICF); 2.

Patients with clinically suspected or confirmed malignancies (supported by evidence such as relevant serum tumor markers, imaging modalities including ultrasound, CT, and MRI, or histopathological examinations) who are in good general condition; 5. Women of childbearing potential (WOCBP) must have used effective contraception for at least one month prior to screening and agree to continue contraceptive use throughout the study period and for a specified duration following study completion; 6. Must meet any other protocol-specified inclusion criteria. Exclusion Criteria: Any subject meeting any of the following baseline criteria will be excluded from the study: 1. Inability to tolerate or complete SPECT/CT examinations (including, but not limited to, the inability to lie supine, claustrophobia, radiophobia, etc.); 2. Presence of other comorbidities, such as acute systemic illnesses and electrolyte imbalances; 3. Known allergy or hypersensitivity to the LRRC15 radiotracer or its synthetic excipients; fasting blood glucose level exceeding 11.0 mmol/L prior to \[¹⁸F\]FDG injection; 4. Patients deemed by the investigator to have poor expected compliance; 5. Pregnant or lactating (nursing) women; 6. Presence of any other conditions or factors that, in the opinion of the investigator, would make the subject unsuitable for participation in this trial.
