Superior antitumor immune response achieved with proton over photon immunoradiotherapy is amplified by the nanoradioenhancer NBTXR3. (PubMed, J Nanobiotechnology)
Mice achieving remission through NBTXR3 + PRT + αPD1 exhibited a robust memory immune response, effectively inhibiting growth of subsequent tumors from three distinct lung cancer cell lines. Proton IRT combined with NBTXR3 offers enhanced tumor control and survival rates over photon-based treatments in managing αPD1-resistant lung cancer, indicating its potential as a potent systemic therapy.

Assessment of the Spatial Bio-Distribution of NBTXR3 for Locally Advanced or Borderline-Resectable Pancreatic Ductal Adenocarcinoma (LAPC or BRPC) Patients Undergoing Radiation Therapy. (PubMed, Int J Radiat Oncol Biol Phys)
The raw volume of NBTXR3 injected in the pancreas did not significantly change over the duration of the three weeks of treatment. We also did not observe significant changes in the NBTXR3 volume overlapping the GTV in most cases. The stability of NBTXR3 was demonstrated during RT.

Novel Radioenhancer NBTXR3 Activated by Radiotherapy in Cisplatin-Ineligible Locally Advanced HNSCC Patients: Final Results of a Phase I Trial. (PubMed, Int J Radiat Oncol Biol Phys)
NBTXR3 IT injection followed by activation with RT was confirmed to be feasible and well tolerated in elderly or frail patients with LA HNSSC and significant comorbidities. The high rate of best overall response suggests that NBTXR3+RT is effective in this elderly population ineligible to cisplatin with a high unmet medical need. These results support our ongoing phase III study comparing NBTXR3/RT ± cetuximab vs. RT ± cetuximab in platinum-based chemotherapy ineligible elderly patients with LA-HNSCC: NANORAY 312 (NCIT04892173).

Phase I study of endoscopic ultrasound (EUS)-guided NBTXR3 delivery activated by radiotherapy (RT) for locally advanced or borderline resectable pancreatic cancer (LAPC or BRPC) (ESMO 2023)
Conclusions The RP2D of NBTXR3 for LAPC is 42% of GTV. The successful CR and shift to resectability in this patient population, along with the response and CA19-9 decrease and normalization suggest promising anti-tumor efficacy of NBTXR3/RT.

Nanoparticle-enhanced proton beam immunoradiotherapy drives immune activation and durable tumor rejection. (PubMed, JCI Insight)
This response was further significantly enhanced by the injection of the tumor to be irradiated with NBTXR3 nanoparticles. Tumors of mice treated with the triple combination exhibited increased infiltration and activation of cytotoxic immune cells. This triple combination eradicated both tumors in 37.5% of the treated mice and showed robust long-term immunity to cancer.

A phase Ib/II trial of PEP503 (NBTXR3, radioenhancer) with radiotherapy and chemotherapy in patients with rectal cancer. (PubMed, Nanomedicine (Lond))
Patients will receive a single intratumoral injection of the nanoparticles, followed by radiotherapy and intravenous infusion of fluorouracil or oral capecitabine concurrently. This study will be the first prospective, open-label, single-arm, nonrandomized study to investigate the efficacy and safety profile of PEP503 (NBTXR3) nanoparticles with radiotherapy and chemotherapy in these patients. Trial registration number: NCT02465593 (ClinicalTrials.gov).

Early biological impacts of radiotherapy-activated NBTXR3 nanoparticles (AACR 2023)
Following LMP, we measured a significant increase of in lipid peroxidation. These first elements allow a better understanding of the early biological consequences induced by NBTXR3+RT, compared to RT alone.

Combining a nanoparticle-mediated immunoradiotherapy with dual blockade of LAG3 and TIGIT improves the treatment efficacy in anti-PD1 resistant lung cancer. (PubMed, J Nanobiotechnology)
Our results strongly attest to the efficacy and validity of combining nanoparticle-enhanced radiotherapy and simultaneous blockade of multiple immune checkpoint receptors and provide a pre-clinical rationale for investigating its translation into human patients.

Nanoparticle-enhanced radiotherapy combined with triple blockade of PD1, LAG3, and TIGIT enhances anti-tumor immune activation (AACR 2022)
Simultaneous inhibition of LAG3 and TIGIT in tandem with PD1 blockade and NBTXR3-enhanced radiotherapy promotes immune activation at the irradiated site. In addition, abscopal immune responses are improved with blockade of LAG3 and TIGIT. These results suggest that blockade of multiple immune checkpoints in parallel with NBTXR3-mediated radiotherapy may be effective in metastatic cancers.[Y.H.

[VIRTUAL] Overcoming Resistance to Anti-PD-1 With Tumor Agnostic NBTXR3: From Bench to Bedside (ASTRO 2021)
The clinical efficacy of NBTXR3+RT has been demonstrated as a single agent in STS. Here we demonstrate that it overcomes resistance to anti-PD-1 treatment mechanisms in mice and led to tumor regression in patients having progressed on anti-PD-1 therapy. These results highlight the potential of NBTXR3+RT to positively impact the immuno-oncology field.

Dual blockade of LAG3 and TIGIT improves the treatment efficacy of a nanoparticle-mediated immunoradiation in anti-PD1 resistant lung cancer in mice (SITC 2021)
Furthermore, Nanostring transcriptomic analysis of cells isolated from the tumors of mice thus treated showed evidence of classical two-step immunological priming, with an elevation of innate immune genes at the primary tumor and full-blown activation of the immune system within the secondary tumor. Conclusions Blockade of TIGIT and LAG3 with NBTXR3+XRT+aPD1 improved CD8+ T-cell proliferation, augmented the antitumor response at both irradiated and unirradiated (abscopal) tumors, and induced potent long-term antitumor memory in mice.
