Nanobiotix Announces Protocol Amendment to Ongoing Global Phase 3 Head and Neck Cancer Study
PARIS and CAMBRIDGE, Mass., May 04, 2026 (GLOBE NEWSWIRE) -- NANOBIOTIX (Euronext: NANO –– NASDAQ: NBTX – the ‘‘Company’’), a late-stage clinical biotechnology company pioneering physics-based approaches to expand treatment possibilities for patients with cancer and other major diseases, today announced FDA acceptance of a protocol amendment to the ongoing pivotal NANORAY-312 study.
This protocol amendment, submitted by NANORAY-312 global sponsor Johnson & Johnson, eliminates the previously planned interim analysis and modifies the final analysis to include fewer events than originally planned and to be conducted sooner.
In Nanobiotix’s view, this decision could accelerate and expand the global registration pathway for JNJ-1900 (NBTXR3) in head and neck cancer, providing the opportunity for earlier increased revenue generation for the Company.
Nanobiotix anticipates that the modified final analysis should readout in the same timeframe as the previously planned interim analysis. Exact timing will depend on when clinical events occur.
Per the license agreement, Nanobiotix is eligible to receive hundreds of millions in aggregate payments in the next few years, subject to the achievement of remaining development and regulatory milestone events related to the first two programs evaluating JNJ-1900 (NBTXR3) in head and neck cancer and lung cancer.
About JNJ-1900 (NBTXR3)
JNJ-1900 (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 through a successful randomized Phase 2/3 study in 2018. The product candidate’s 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 JNJ-1900 (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 JNJ-1900 (NBTXR3) is being evaluated across multiple solid tumor indications as a single agent or combination therapy. The program is led by 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 JNJ-1900 (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.
Given the Company’s focus areas, and balanced against the scalable potential of NBTXR3, Nanobiotix has engaged in a collaboration strategy to expand development of the product candidate in parallel with its priority development pathways. Pursuant to this strategy, in 2019 Nanobiotix entered into a broad, comprehensive clinical research collaboration with The University of Texas MD Anderson Cancer Center to sponsor several Phase 1 and Phase 2 studies evaluating JNJ-1900 (NBTXR3) across tumor types and therapeutic combinations. In 2023, Nanobiotix announced a license agreement for the global co-development and commercialization of JNJ-1900 (NBTXR3) with Janssen Pharmaceutica NV, a Johnson & Johnson company.
