Clinical trials

This is a single arm, open label, multi-center phase I study, including phase Ia dose escalation and phase Ib dose expansion. Safety review committee (SRC) will be formed to monitor safety and efficacy data through the study. And the independent review committee (IRC) will be formed to monitor efficacy data through the study.

Stage 1 (Safety study for 68Ga-NRT6020 Injection): The goal of this clinical trial stage is to evaluate the safety of 68Ga-NRT6020 Injection in participants with advanced solid tumors. The study will also assess the biodistribution, radiation dosimetry, imaging profile, and pharmacokinetics of the drug. Additionally, researchers aim to investigate how consistent the PET/CT imaging results of 68Ga-NRT6020 are with 18F-FDG PET/CT imaging and FAP immunohistochemistry (IHC) results. Stage 2 (Safety and tolerability study for 177Lu-NRT6020 Injection): This stage focuses on evaluating the safety and tolerability of 177Lu-NRT6020 Injection in FAP-positive participants with advanced solid tumors. Researchers will also assess the safety of 68Ga-NRT6020 Injection in this population. The study will evaluate the biodistribution, radiation dosimetry, pharmacokinetics, and preliminary efficacy of 177Lu-NRT6020 Injection. Additionally, the imaging profile of 68Ga-NRT6020 and its consistency with other imaging techniques will be further investigated. Stage 3 (Preliminary efficacy study for 68Ga/177Lu-NRT6020 Injection): The objective of this stage is to evaluate the safety of 177Lu-NRT6020 Injection and 68Ga-NRT6020 Injection in FAP-positive participants with advanced solid tumors, as well as to determine the recommended phase 2 dose (RP2D) of 177Lu-NRT6020 Injection. The study will also assess the preliminary efficacy, biodistribution, radiation dosimetry, and pharmacokinetics of the drugs. Furthermore, researchers will investigate the imaging profile of 68Ga-NRT6020 and its consistency with other imaging techniques.
