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 volunteers

Qualifiers

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 outcomes

Primary outcomes

1

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.

Time frame
Within 1 week after PET imaging.

Secondary outcomes

1

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.

Time frame
Within 2 week after surgery.
