Motivation for the study Glioblastoma is the most aggressive and lethal brain cancer with an average prognosis of 15 months. Fluorescence-guided surgery (FGS) for glioblastoma was FDA-approved in 2017, while photodynamic therapy (PDT) remains an active area of clinical investigation with very promising results so far. The aim of PDT is to eradicate the

Motivation for the study The motivation was to study if photoimmunotherapy could enhance anti-tumor immunity when combined with immune checkpoint inhibition. CD44-targeted photoimmunotherapy was applied against poorly immunogenic, “cold” tumor and antitumor effect was studied alone and in combination with anti-PD-1 immune checkpoint inhibition. Sensitization of this “cold” tumor to immune checkpoint inhibition after photoimmunotherapy

Results Tumor growth was significantly suppressed by photoimmunotherapy, compared to control or IgG without light activation. Tumor growth suppression, as well as overall survival after photoimmunotherapy, were significantly better with F(ab´)2 fragments than with full IgG. This efficacy improvement might be related to killer T cells, which were detected in much higher numbers
