Jager    Published in: Cancer Immunology, Immunotherapy Authors: Ruben V. Huis in ‘t Veld, Sen Ma, Rhonda C. Kines, Anneli Savinainen, Cadmus Rich, Ferry Ossendorp, Martine J. Jager   AU-011 combination with immune checkpoint inhibitors (ICI) was studied in murine models. This has potential to improve treatment efficacy against metastatic tumors by abscopal immune effects. ICI was shown to increase AU-011 efficacy and also result in abscopal effect and induced complete responses in 75% of animals. ML6700 was used as illumination source for PDT. Metastases remain the Continue reading →

Choyke, Hisataka Kobayashi   The study aimed to develop photoimmunotherapy for pigmented melanoma, which can challenging indication since the pigment could absorb light and make treatment ineffective. In vitro & in vivo studies with ML7710 laser compared PIT against pigmented and non-pigmented melanoma and found no differences. CD29 targeted PIT was more effective than CD44 targeted PIT, relating to expression of CD44 on Continue reading →

Also the combination of AU-011 with immune checkpoint inhibitor antibodies (anti-CTLA-4 or anti-PD-1) was studied and improved therapeutic efficacy. Modulight laser + MLAKIT was used only for Continue reading →
