(AOF) – During the Society for Neuro-Oncology annual meeting, Noxxon Pharma presented the results of 9 chemotherapy-unresponsive patients (unmethylated MGMT promoter) participating in the proof of concept study on the inhibition of CXCL12 during and after radiotherapy in the treatment of glioblastoma. 8 of 9 patients (89%) treated with NOX-A12 showed reduction in tumor size (2 patients with objective responses – reduction> 50% – and 6 patients showed stabilization of the disease – reduction
These results compare favorably with historical results for patients in a matched cohort who received standard treatment, where only 1 in 13 (8%) patients experienced a reduction in tumor size with an objective response and where tumors of 12 patients progressed.
Likewise, the data from the analysis of the tissues of a patient under treatment with NOX-A12 show a significant reduction of the target of NOX-A12, CXCL12, on the blood vessels of the tumor, a significant decrease in proliferation. tumor cells and increased tumor infiltration of activated killer immune cells. Interestingly and very importantly, these benefits have been seen on all available tumor tissue and not just on small subsections.
