Using 68Ga-NY104 PET/CT to detect clear cell renal cell carcinoma recurrence or metastasis

68Ga-NY104 PET/CT in Patients With Metastasis/Recurrence Clear Cell Renal Cell Carcinoma Suspicion: a Prospective, Single Center, Single Arm Imaging Trial

Phase 2 Interventional Peking Union Medical College Hospital · NCT05879497

This study is testing a new type of imaging called 68Ga-NY104 PET/CT to see if it can help find signs of recurrence or spread of clear cell kidney cancer in patients who might have it.

What this trial studies

This phase 2 clinical trial is designed to evaluate the effectiveness of 68Ga-NY104 PET/CT imaging in patients suspected of having metastasis or recurrence of clear cell renal cell carcinoma (ccRCC). The study will involve administering a single dose of 68Ga-NY104 to participants, followed by whole-body PET/CT imaging. Two independent readers will interpret the imaging results to assess the sensitivity and specificity of this diagnostic approach. A total of 40 patients will be recruited at Peking Union Medical College Hospital for this prospective, single-center study.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with a confirmed diagnosis of clear cell renal cell carcinoma and suspected metastasis or recurrence.

Not a fit: Patients currently undergoing treatment with VEGF TKIs or HIF antagonists may not benefit from this study due to potential interference with the imaging agent.

Why it matters

Potential benefit: If successful, this study could improve the accuracy of diagnosing metastasis or recurrence in patients with clear cell renal cell carcinoma.

How similar studies have performed: While the use of PET/CT imaging in oncology is well-established, the specific application of 68Ga-NY104 for ccRCC is novel and has not been extensively tested in prior studies.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

1. Age ≥ 18 y
2. Histopathological diagnosis of clear cell renal cell carcinoma
3. Suspected of metastasis or recurrence from ccRCC based on previous conventional imaging or 18F-FDG PET/CT scan.
4. Expected survival of at least 6 months
5. ECOG ≤ 2
6. Written informed consent provided for participation in the trial
7. In the opinion of investigator, willing and able to comply with required study procedures.

Exclusion Criteria:

1. 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-NY104. 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.
2. 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-1. 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.
3. Pregnancy or breastfeeding.
4. Severe claustrophobia.
