NANOBIOTIX and LianBio Announce First Patient Enrolled in Asia in Phase 3 NANORAY-312 Trial Evaluating NBTXR3 for the Treatment of Head and Neck Cancer

Regulatory News:

NANOBIOTIX (Euronext: NANO – Nasdaq: NBTX), a late-stage clinical biotechnology company pioneering physics-based approaches to expand treatment possibilities for patients with cancer, and LianBio (Nasdaq: LIAN), a biotechnology company dedicated to bringing paradigm-shifting medicines to patients in China and major Asian markets today announced randomization of the first patient in Asia in NANORAY-312, a global Phase 3 registrational trial evaluating NBTXR3 for the treatment of elderly patients with locally advanced head and neck squamous cell carcinoma (“LA-HNSCC”) who are ineligible for platinum-based chemotherapy.

“We believe NBTXR3 has demonstrated the potential to improve treatment outcomes in multiple solid tumor indications, including in Study 102, the Nanobiotix Phase 1 trial evaluating the product candidate for the treatment of elderly patients with locally advanced head and neck squamous cell carcinoma,” said Yizhe Wang, Ph.D., Chief Executive Officer, LianBio. “We look forward to working with our clinical partners at sites across Greater China and South Korea to evaluate NBTXR3 in this difficult-to-treat patient population. With radiotherapy usage on the rise in Asia, we believe NBTXR3 may become an important part of the treatment landscape for patients with cancer in the region.”

NANORAY-312 is a global, two-arm, randomized, Investigator’s Choice Phase 3 registrational study that is designed to investigate the efficacy and safety of radiotherapy-activated NBTXR3 with or without cetuximab versus radiotherapy with or without cetuximab in high-risk, chemotherapy-ineligible elderly patients with LA-HNSCC. Eligible participants for NANORAY-312 will be treated with NBTXR3 at a 1:1 ratio after an Investigator’s Choice of radiotherapy alone or radiotherapy in combination with cetuximab. This pivotal trial is expected to enroll 500 patients globally, with approximately 100 patients expected to be enrolled in LianBio’s licensed territories participating in the study.

NANORAY-312 builds on Nanobiotix Study 102, a Phase 1 trial evaluating safety and early signs of efficacy for radiotherapy-activated NBTXR3 in high-risk elderly LA-HNSCC patients who are chemotherapy-ineligible and intolerant to cetuximab. To date, Study 102 has demonstrated median overall survival of 17.9 months in the all-treated population (n=56) and 23.0 months in the evaluable patients (n=44).
