About

Clinical study of a novel oncolytic virus Ad-TD-nsIL12 in the treatment of primary high-grade glioma

Full description

This study will conduct two prospective, single-arm, single-center, exploratory clinical trials aimed at assessing the preliminary efficacy and safety of the novel oncolytic adenovirus Ad-TD-nsIL12 in treating primary HGG. Trial 1 will preliminarily evaluate the efficacy and safety of Ad-TD-nsIL12 as neoadjuvant treatment for patients with non-functional zone primary HGG; Trial 2 will preliminarily evaluate the efficacy and safety of Ad-TD-nsIL12 in treating patients with functional zone and thalamic primary HGG, as well as their quality of life.

The lesion is located in the non-functional area (Experiment 1) / the lesion is located in the functional area and thalamus (Experiment 2);
Have an intracranial measurable target lesion (refer to the iRANO standard);
