PARIS and CAMBRIDGE, Mass., Nov. 12, 2024 (GLOBE NEWSWIRE) -- NANOBIOTIX (Euronext: NANO - NASDAQ: NBTX - the "Company"), a late-clinical stage biotechnology company pioneering nanoparticle-based approaches to expand treatment possibilities for patients with cancer and other major diseases, provided an update on operational progress and reported financial results for the third quarter of 2024.

"Our strong momentum continues as we further execute across initiatives designed to advance our potentially first-in-class nanoparticle-based therapeutic platforms for millions of patients worldwide. In the NBTXR3 program, we began sponsorship transfer of our global, pivotal NANORAY-312, which is a key step for the potential regulatory submission of NBTXR3 and the promise of our lead candidate to help address the unmet needs of 12 million patients with solid tumors globally who receive radiotherapy each year," said Laurent Levy, co-founder of Nanobiotix and chairman of the executive board. "We were also pleased to expand our Supervisory Board to include leading experts in both the scientific and financial communities to help foster sustainable long-term growth across our platforms. In the fourth quarter, we expect updated dose escalation data for NBTXR3 in pancreatic cancer from our MD Anderson collaboration, as well as an update to our Curadigm program, which is the next-wave of nanoparticle-based platforms from Nanobiotix."

Third Quarter 2024 Operational Highlights

In an important step forward for the potential NBTXR3 regulatory pathway, Nanobiotix and Janssen Pharmaceutica NV, a Johnson & Johnson Company ("Janssen"), have initiated the planned sponsorship transfer of NANORAY-312, a global Phase 3 study evaluating radiotherapy-activated NBTXR3 for patients with head and neck cancer ineligible for cisplatin, from Nanobiotix to Janssen. Nanobiotix has transferred the sponsorship of the study in the United States to Janssen as planned. The process of transferring the remaining global regions is ongoing. Nanobiotix estimates this process will require several quarters to complete. Janssen is the global licensee for NBTXR3 co-development and commercialization. Accountability for the NANORAY-312 sponsorship will enable the licensee to submit NBTXR3 for global registration in the event of positive trial results.

The Company strengthened its Supervisory Board with the nominations of Dr. Margaret A. Liu and Ms. Anat Naschitz as board observers, two key additions intended to further equip the Company for sustainable long-term growth. Dr. Liu brings a wealth of experience in US and international academia, pharmaceuticals, biotechnology and public policy, and Ms. Naschitz brings world-class expertise in raising and deploying capital to support disruptive innovation for the benefit of patients, healthcare professionals and investors.

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.

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 NBTXR3 across tumor types and therapeutic combinations. In 2023, Nanobiotix announced a license agreement for the global co-development and commercialization of NBTXR3 with Janssen Pharmaceutica NV.
