简要总结

The purpose of this study is to explore the effectiveness of 18F-G1 PET/CT in patients with solid tumors and hematological malignancies receiving immunotherapy

详细描述

It is urgent to select patients who will benefit from immunotherapy, so as to help the clinicians adjust the regimens and avoid unnecessary side effect. 18F-G1 is a new radioactive tracer targeting granzyme B, holding great promise in assessing early response to immunotherapy. This study will explore the safety of 18F-G1 PET/CT in patients with solid tumors and hematological tumors receiving immunotherapy, analyze its imaging features, and assess its efficacy in predicting early immunotherapy response and prognosis, so as to aid the clinicians in precise patient stratification and regimen adjustment.

时间窗: 40-60 minutes after the injection of 18F-G1

The uptake of 18F-G1 in liver will be quantitatively assessed by SUVmax.

Lung uptake of 18F-G1

时间窗: 40-60 minutes after the injection of 18F-G1

The uptake of 18F-G1 in lung will be quantitatively assessed by SUVmax.

Kidney uptake of 18F-G1

时间窗: 40-60 minutes after the injection of 18F-G1

The uptake of 18F-G1 in kidney will be quantitatively assessed by SUVmax.

the granzyme B specificity of 18F-G1

时间窗: 3 years

Number of participants with 18F-G1-related adverse events (AEs).

时间窗: 3 days after the injection of 18F-G1

The absolute number of participants with AEs after the injection of 18F-G1 according to CTCAE 5.0.

The vivo accumulation and distribution of 18F-G1 in tumors and major healthy organs.

时间窗: 40-60 minutes after the injection of 18F-G1

The accumulation and distribution of 18F-G1 in tumors and major healthy organs, such as liver, lung, kidney, will be quantitatively and qualitatively examined.

Assessing the early predictive value of 18F-G1 PET/CT for immunotherapy response.

时间窗: 6 months

Participants' overall response will be assessed by RECIST 1.1 criteria or Lugano criteria at the time point of 6 months after immunotherapy. The tumor uptake of 18F-G1 will be compared between the responders and non-responders.

次要结局

  • Evaluate the correlation of 18F-G1 accumulation in tumors to long term survival after immunotherapy.(3 years)
