Clinical Trial Summary

Primary objective To investigate the safety and tolerability profile of 68Ga- NODAGA-SNA006 in patients with solid tumors; To investigate the radiation absorbed dose characteristics of 68Ga-NODAGA-SNA006 in patients with solid tumors; To investigate the distribution profile of 68Ga-NODAGA-SNA006 in patients with solid tumors. Secondary objectives To investigate the optimal administration dose and radiation safety profile of 68Ga-NODAGA-SNA006; To investigate the PET imaging characteristics and high-quality imaging time window of 68Ga-NODAGA-SNA006 in patients with solid tumors; To explore the correlation between PET imaging characteristics of 68Ga-NODAGA-SNA006 binding to CD8 and histological CD8 expression characteristics; To explore peripheral blood T lymphocyte differentiation (CD8, CD4, CD3, etc.) in patients with solid tumors.


Description:

The study had a dose-escalation, open-label design. Intravenous injection of SNA006 was used to observe its safety tolerance, radiation absorbed dose, distribution, and PET imaging characteristics in patients with solid tumors. The study consists of three phases, namely, a screening period, a trial period, and a safety follow-up period. 1. Safety evaluation Observe any AE occurred in all subjects during the clinical study, record the clinical features, severity, occurrence time, end time, duration, treatment measures and outcome, and determine the correlation between any AE and the study drug. 2. efficacy evaluation 2.1. Evaluation of imaging characteristics In this clinical trial, PET imaging characteristics will be evaluated by an independent imaging evaluation committee, and the PET imaging operating procedures and parameters will be detailed in the PET/CT standard operating procedures. 2.2. Evaluation of correlation between imaging expression and immunohistochemistry.

Outcome

Type Measure Description Time frame Safety issue
Primary Safety evaluation indicators AE/SAE/SUSAR. To observe AE/SAE/SUSAR of subjects during trial period, until 12 months after trial finished. 12 months
Secondary Immunogenicity evaluation ADA blood samples were collected twice, and tested in an independent third party central laboratory. Then, ADA positive rate were analysied. 1 week
Secondary Evaluation of imaging characteristics Target/background ratio in PET imaging of tumor lesions was calculated, compared target lesions with contralateral lesions, liver and muscle. 12 months
Secondary Evaluation of the correlation between imaging expression and immunohistochemistry Immunohistochemical analysis (third-party independent central laboratory testing) was performed on the collected tumor tissue samples, and the scoring results were compared with the imaging expression results to calculate the sensitivity, specificity and other results. 12 months
