Brief summary

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.

Detailed description

During the study, 68Ga-NRT6020 served as the companion diagnostic agent for 177Lu-NRT6020 to select eligible patients. This stage 2 and stage 3 of the study is designed as a multi-center, multiple-dose, parallel-cohort study, and will enroll FAP-positive (FAP-positive is defined by positive PET/CT imaging results for 68Ga-NRT6020; and dose of 68Ga-NRT6020 will be confirmed by the SRC after stage 1) patients with advanced solid tumors who have failed or have no available standard therapy.

Interventions

DIAGNOSTIC_TEST68Ga-NRT6020 Injection

Participants will receive a single intravenous injection of 68Ga-NRT6020 Injection (3 mCi or 5 mCi) and PET/CT scans at multiple time points.

DRUG177Lu-NRT6020 Injection (stage 2)

It is planned to evaluate 4 dose levels of 177Lu-NRT6020 Injection: 50mCi, 100mCi, 150mCi and one/more adaptive dose groups (ranged from 150 to 250 mCi, the specific doses and/or doses with other frequencies within the range of 150\~250mCi, need to be determined after the completion of the dose-limiting toxicity (DLT) assessment for the previous three dose groups, in combination with the safety, pharmacokinetics and radiation dosimetry results of the participants, following confirmation by the SRC) which will be administered every 6 weeks (Q6W), and/or other dosing intervals determined by the SRC, for up to 6 cycles.

DRUG177Lu-NRT6020 Injection (stage 3)

Participants will receive intravenous injection of 177Lu-NRT6020 Injection, administered Q6W and/or other dosing intervals determined by the SRC, for up to 6 cycles.
