2021 – Dual blockade of LAG3 and TIGIT improves the treatment efficacy of a nanoparticle-mediated immunoradiation in anti-PD1 resistant lung cancer in mice

129Sv/Ev mice were inoculated with 50,000 aPD1-resistant 344SQR cells in the right leg on day 0 (primary tumor) and with 50,000 cells in the left leg on day 4 (secondary tumor). Primary tumors were injected with NBTXR3 radioenhancer nanoparticles on day 7 and irradiated with 12 Gy on days 8, 9, and 10. Anti-PD1, aLAG3, and aTIGIT were given to mice by intraperitoneal injections on days 5, 8, 11, 14, 21, 28, 35, and 42. […]

2021 – NBTXR3 activated by SBRT combined with nivolumab or pembrolizumab in patients with advanced cancers: phase I trial

Immune checkpoint inhibitors (ICIs) have improved treatment outcomes in a variety of cancers; however the majority of patients (pts) exhibit resistance. Emerging evidence suggests radiation therapy (RT) can enhance response to ICIs by producing an immunomodulatory effect. NBTXR3, composed of functionalized hafnium oxide nanoparticles, is injected intratumorally and activated by RT. […]
