简要总结
This is a prospective, single-center, single-arm phase 2 study in patients with clear cell renal cell carcinoma and metastasis or recurrence suspicion. The goal is to determine the sensitivity and specificity of 68Ga-NY104 PET/CT in patients with clear cell renal cell carcinoma and metastasis or recurrence suspicion
详细描述
This is a prospective, single-center, single-arm phase 2 study in patients with clear cell renal cell carcinoma and metastasis or recurrence suspicion. Each patient will receive one dose of 68Ga-NY104. Dedicated whole-body PET/CT imaging will be performed. PET/CT studies will be interpreted by two readers, both of whom will provide independent and blinded interpretations. Imaging interpretations and a composite ground truth will be used to estimate the diagnostic efficacy of 68Ga-NY104 PET/CT.
A total of 40 patients will be recruited at Peking Union Medical College Hospital.

入选标准
- •Histopathological diagnosis of clear cell renal cell carcinoma
- •Suspected of metastasis or recurrence from ccRCC based on previous conventional imaging or 18F-FDG PET/CT scan.
- •Expected survival of at least 6 months
- •Written informed consent provided for participation in the trial
- •In the opinion of investigator, willing and able to comply with required study procedures.
排除标准
- •On VEGF TKI treatment less than 1 week before 68Ga-NY104 PET/CT. TKI is known to affect girentuximab binding in patients with ccRCC and is expected to have the same effect on 68Ga-NY
- •If patients were on VEGF TKI treatment, such as sunitinib, sorafenib, cabozantinib, pazopanib, or lenvatinib, a washout of one week before 68Ga-NY104 PET/CT is required.
- •Patients on HIF antagonist treatment < 3 months before 68Ga-NY104 PET/CT. CA9, which encodes carbonic anhydrase IX (CAIX), is one of the genes most strongly upregulated by HIF-
- •HIF antagonist, such as Belzutifan, might affect the expression of CAIX and thus the binding of 68Ga-NY104 to tumor. Withdraw of at least 3 months is required for HIF antagonist.
- •Pregnancy or breastfeeding.
- •Severe claustrophobia.
结局指标
主要结局
Binary reading of lesions identified on 68Ga-NY104 PET/CT
时间窗: From study completion to 1 month after completion
Any focal accumulation in the lesion suspected of metastasis or recurrence that cannot be explained by physiologic uptake of 68Ga-NY104 will be interpreted as PET positive.
