Conditions
Summary
This study is an open-label, single-arm, interventional clinical trial designed to investigate the safety of ⁶⁸Ga/¹⁷⁷Lu-BRP-020063 in patients with advanced metastatic solid tumors; to evaluate the pharmacokinetics, biodistribution, and radiation dosimetry of ¹⁷⁷Lu-BRP-020063 in patients with metastatic solid tumors; and to preliminarily explore its therapeutic efficacy. The study plans to enroll 10 patients to receive ⁶⁸Ga-BRP-020063 PET/CT imaging, among whom 5 patients positive for ⁶⁸Ga-BRP-020063 will be selected to receive a low dose of ¹⁷⁷Lu-BRP-020063. The results of this study will provide a basis for the design of subsequent studies involving higher doses of ¹⁷⁷Lu-BRP-020063.

Interventions
68Ga-BRP-020063 Injection (Diagnostic Phase): All subjects will receive a single administration of 68Ga-BRP-020063 injection. The dose of 5 mCi (185 MBq), within an acceptable range of 3-7 mCi (111-259 MBq), will be delivered via rapid consecutive intravenous bolus injection in a volume not exceeding 10 mL, followed by a saline flush. 177Lu-BRP-020063 Injection (Therapeutic Phase): Five subjects who show positive results on the 68Ga-BRP-020063 PET/CT scan will be selected to receive a single administration of 177Lu-BRP-020063 injection. A dose of 40 mCi (1.48 GBq), within an acceptable range of 30-50 mCi (1.11-1.85 GBq), will be administered via intravenous infusion over approximately 20 minutes using an infusion pump, followed by a saline flush.
