2021 – Radiotherapy-activated NBTXR3 nanoparticles Increase CD8+ T cell infiltration and diversity in tumors, and modulate the immunopeptidome of cancer cells

Abstracts, In Vitro in Vivo NBTXR3, In Vivo

When exposed to radiotherapy (RT), NBTXR3 nanoparticles increase radiation dose deposition from within the cancer cells. NBTXR3 is intended for a single intratumor injection. Results from a phase II/III clinical trial in patients with locally advanced Soft Tissue Sarcoma demonstrated significant superiority and clinical benefits of NBTXR3 activated by RT compared to RT alone […]

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

Abstracts, In Vitro in Vivo NBTXR3, In Vivo, Non classifié(e)

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 – A phase I dose expansion study of NBTXR3, radiation enhancing hafnium oxide nanoparticles, for the treatment of cisplatin-ineligible locally advanced HNSCC patients

Abstracts, Donnée clinique de NBTXR3, NO-RIGHTS, Tête & Cou

Non-surgical standard of care (SOC) for locally advanced head and neck squamous cell carcinoma (LA HNSCC) patients is chemoradiation with cisplatin/cetuximab. Elderly patients, and those with poor performance status, comorbidities, and/or intolerance, may not benefit from current SOC, representing a high unmet need. NBTXR3, a novel radioenhancer composed of functionalized hafnium oxide nanoparticles. […]

2021 – Study of Novel Radioenhancer NBTXR3 Plus Radiotherapy in Patients With Locally Advanced Soft Tissue Sarcoma: Results of the Long-Term Evaluation in the Phase II/III Act.In.Sarc Trial

Abstracts, Donnée clinique de NBTXR3, STM

NBTXR3, a novel radioenhancer activated by radiotherapy (RT) demonstrated superior efficacy, as preoperative treatment in patients with locally advanced soft tissue sarcoma (LA STS) compared to RT alone. […]

2021 – Overcoming Resistance to Anti-PD-1 With Tumor Agnostic NBTXR3: From Bench to Bedside

Abstracts, In Vitro in Vivo NBTXR3, In Vivo

Immune checkpoint inhibitors (ICI) can improve outcomes in patients who respond to treatment, however most patients exhibit resistance. Overcoming this resistance is the main challenge in immune-oncology and recent studies suggest radiotherapy (RT) may improve ICI response rates. NBTXR3, composed of functionalized hafnium oxide nanoparticles, is injected intratumorally and activated by RT. […]

2021 – NBTXR3 Activated by Radiotherapy in Combination With Nivolumab or Pembrolizumab in Patients With Advanced Cancers: A Phase I Trial

Abstracts, Donnée clinique de NBTXR3, Foie, Poumon, Tête & Cou

Immune checkpoint inhibitors (ICIs) have led to improved treatment outcomes in a variety of cancers; however, the majority of patients exhibit resistance to ICIs. Overcoming this resistance is a major challenge in immune-oncology. Radiation therapy (RT) has emerged as a promising combination with ICIs since it may act synergistically with ICIs by producing an immunomodulatory effect. […]

2021 – Phase I study of functionalized hafnium oxide nanoparticles (NBTXR3) activated by radiotherapy in cisplatin-ineligible locally advanced HNSCC patients

Abstracts, Donnée clinique de NBTXR3, NO-RIGHTS, Tête & Cou

The non-surgical standard of care (SOC) for the treatment of locally advanced head and neck squamous cell carcinoma(LA HNSCC) is concurrent chemoradiation with high dose cisplatin or cetuximab in case of contra-indication to cisplatin. However elderly patients, and those with poor performance status, comorbidities, and/or intolerance, may not benefit from these SOC treatments and represent a high unmet need. […]

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

Abstracts, Donnée clinique de NBTXR3, Foie, Non classifié(e), Poumon, Tête & Cou

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. […]

2021 – Phase I Study of Novel Radioenhancer NBTXR3 Activated by Radiotherapy in Cisplatin-Ineligible Locally Advanced HNSCC Patients

Abstracts, Donnée clinique de NBTXR3, Tête & Cou

Concurrent radiotherapy (RT) with high-dose cisplatin, or cetuximab in case of intolerance to cisplatin, are the non-surgical standard treatment for locally advanced head and neck squamous cell carcinoma (LA HNSCC). However, elderly patients, patients with poor performance status, comorbidities, and/or intolerance may not benefit from these treatments […]
