NANOBIOTIX Announces US FDA Protocol Acceptance for New Randomized Phase 2 Study Evaluating NBTXR3 for Patients with Stage Three Lung Cancer

PARIS and CAMBRIDGE, Mass., May 14, 2024 (GLOBE NEWSWIRE) -- NANOBIOTIX (Euronext: NANO –– NASDAQ: NBTX – the ‘‘Company’’), a late-clinical stage biotechnology company pioneering nanoparticle-based therapeutic approaches to expand treatment possibilities for patients with cancer and other major diseases, today announced that the U.S. Food and Drug Administration (“US FDA”) issued a Study May Proceed Letter for a randomized Phase 2 study evaluating NBTXR3 for the treatment of patients with stage 3, unresectable non-small cell lung cancer (“NSCLC”). An IND to support this trial was submitted by the global trial sponsor, Johnson & Johnson Enterprise Innovation Inc., a Johnson & Johnson company.

“The NBTXR3 collaboration established by our global licensing agreement with Janssen Pharmaceutica NV continues to make progress toward our goal of reaching millions of patients with cancer around the world. The US FDA acceptance of the protocol for this new Phase 2 study has the potential to expand the NBTXR3 development pipeline to a new indication where innovation could potentially provide important outcomes,” said Louis Kayitalire, MD, chief medical officer at Nanobiotix. “We look forward to continuing to prepare for the launch of the study.”

About NBTXR3
NBTXR3 is a novel, potentially first-in-class oncology product composed of functionalized hafnium oxide nanoparticles that is administered via one-time intratumoral injection and activated by radiotherapy. Its proof-of-concept was achieved in soft tissue sarcomas for which the product received a European CE mark in 2019. The product candidate’s physical mechanism of action (MoA) is designed to induce significant tumor cell death in the injected tumor when activated by radiotherapy, subsequently triggering adaptive immune response and long-term anti-cancer memory. Given the physical MoA, Nanobiotix believes that NBTXR3 could be scalable across any solid tumor that can be treated with radiotherapy and across any therapeutic combination, particularly immune checkpoint inhibitors.

Radiotherapy-activated NBTXR3 is being evaluated across multiple solid tumor indications as a single agent or in combination with anti-PD-1 immune checkpoint inhibitors, including in NANORAY-312—a global, randomized Phase 3 study in locally advanced head and neck squamous cell cancers. In February 2020, the United States Food and Drug Administration granted regulatory Fast Track designation for the investigation of NBTXR3 activated by radiation therapy, with or without cetuximab, for the treatment of patients with locally advanced HNSCC who are not eligible for platinum-based chemotherapy—the same population being evaluated in the Phase 3 study.
