Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an open-label, non-controlled, non-randomized study to assess the therapeutic efficacy of 177Lu-AB-3PRGD2 in patients with various solid tumors who will undergo radioligand therapy using 177Lu-AB-3PRGD.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Integrin αvβ3 is highly expressed in some tumor cells and neovascularization, which is an ideal target for diagnosis and treatment of solid tumors. 177Lu-AB-3PRGD2, is a kind of new drug based on independent research and development in China, providing an effective target for the treatment of tumors. All patients underwent whole-body 68Ga-RGD PET/CT for selection and accepted intravenous injection with a fixed dose of 2.96 GBq (80 mCi) of 177Lu-AB-3PRGD2 within one week. Treatment is planned for up to 4 cycles, and the time interval between cycles is 6 weeks. The primary endpoint assessed the preliminary treatment efficacy of 177Lu-AB-3PRGD2 used for radioligand therapy in patients with various advanced tumors. The secondary endpoint evaluates the safety of 177Lu-AB-3PRGD2.
