68Ga-NY104 PET/CT Guided Radiation Therapy in CcRCC.

Phase 2
Recruiting
Conditions
Clear Cell Renal Cell Carcinoma
Interventions
Drug: 68Ga-NY104 PET/CT
Radiation: Radiation Therapy
Drug: Systemic therapy
Registration Number
NCT06613269
Lead Sponsor
Peking Union Medical College Hospital
Brief Summary

Radiation therapy (RT) is an effective treatment for patients with advanced-stage clear cell renal cell carcinoma (ccRCC). Current evidence has shown promising outcomes combining radiation therapy and standard systemic therapy in patients with metastatic/recurrent ccRCC. CAIX is a highly sensitive and specific biomarker expressed on ccRCC and in previous studies our team has shown excellent diagnostic efficacy of 68Ga-NY104, a CAIX-targeted PET tracer, in patients with metastatic ccRCC. In this study, we aim to investigate the effect of 68Ga-NY104, and 18F-FDG PET/CT guided RT combining standard systemic therapy in patients with metastatic ccRCC.

NY104 and FDG guided RT combining systemic therapy68Ga-NY104 PET/CTIn this arm, patients will undergo baseline evaluation using both 68Ga-NY104 and 18F-FGD PET/CT. Metastatic lesions will be identified based on these two PET/CTs and all other imaging modalities available. The radiation field will be planned to cover as much metastasis as possible if not all. Systemic therapy will be delivered at the same time. The patients will be followed up for disease status.

Primary Outcome Measures
NameTimeMethod
Progression free survival 2, PFS2the time from the start of RT to 4 years after treatment

Progression Free Survival 2 (PFS2) was defined as the time from the beginning of treatment to the emergence of new lesions or the progression of original lesions, when the lesions could not be fully covered by radiotherapy, and the drug regimen had to be changed.

Secondary Outcome Measures
NameTimeMethod
Lesion uptake on 68Ga-NY104 PET/CTFrom the start of 68Ga-NY104 PET/CT to 1 week after the 68Ga-NY104 PET/CT
Lesion uptake on 18F-FDG PET/CTFrom the start of 18F-FDG PET/CT to 1 week after the 18F-FDG PET/CT
Number of positive lesions detected on 68Ga-NY104 PET/CTFrom the start of 68Ga-NY104 PET/CT to 1 week after the 68Ga-NY104 PET/CT
Number of positive lesions detected on 18F-FDG PET/CTFrom the start of 18F-FDG PET/CT to 1 week after the 18F-FDG PET/CT
Number of lesions detected combining all available imaging modalitiesFrom the start of any imaging modality to 1 week after completion of all imaging modalities
Objective response ratethe time from the start of RT to 4 years after treatment

The percentage of patients with complete remission or partial remission of tumor after treatment.

Progression free survival 1, PFS1the time from the start of RT to 4 years after treatment

Progression Free Survival 1 (PFS1) was defined as the time from the beginning of treatment to the emergence of new lesions or the progression of original lesions.

Disease control ratethe time from the start of RT to 4 years after treatment

The percentage of patients with complete remission, partial remission, or stable disease after treatment.

Overall survivalthe time from the start of RT to 4 years after treatment
Adverse eventthe time from the start of RT to 4 years after treatment

The adverse event due to PET/CT and treatment will be recorded according to CTCAE 5.0.
