About this trial
This study aims to investigate 68Ga-MY6349, an immune-PET tracer targeting trophoblast cell surface antigen 2 (Trop2), for the noninvasive diagnosis of craniopharyngioma in vivo.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
must be able to provide a written informed consent
radiologically presumed and/or histologically confirmed craniopharyngioma scheduled for resection
adequate clinical condition (Karnofsky performance status ≥70)
Disqualifiers
concomitant major central nervous system disorders
severe hepatic or renal dysfunction
history of severe allergy or hypersensitivity to intravenous radiographic contrast agents
claustrophobia precluding PET/CT or MRI examinations
Trial design

Treatments tested in this trial
68Ga-MY6349 PET/CT
Diagnostic testEach subject receives a single intravenous injection of 68Ga-MY6349 and undergoes PET/CT imaging within the specified time.
Treatment groups
Trial outcomes
Primary outcomes
Standardized uptake value of 68Ga-MY6349 in PET imaging of craniopharyngioma
The semiquantitative analysis will be performed by the same person for all the cases, and the standardized uptake value (SUV) of the tracer in craniopharyngioma will be measured.
Secondary outcomes
Evaluate the feasibility of PET/CT imaging with 68Ga-MY6349 for the non-invasive assessment of Trop2 expression in craniopharyngioma.
Trop2 expression analysis in tumor sample will be correlated to 68Ga-MY6349 tumor uptake, evaluated by measuring standardized uptake value (SUV) on the 68Ga-MY6349 PET/CT.
