PARIS and CAMBRIDGE, Mass., May 21, 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 updates to its corporate strategy designed to enable long-term growth in view of significant progress in the Company’s collaboration for the co-development and global commercialization of lead therapeutic candidate NBTXR3.

Nanobiotix is developing three nanoparticle-based therapy platforms in sequence. The first therapeutic candidate from the first platform, potential first-in-class radioenhancer NBTXR3, is being developed and potentially commercialized in collaboration with NBTXR3 global licensee Janssen Pharmaceutica NV (“Janssen”), a Johnson & Johnson company. Nanobiotix plans to leverage the sustainable revenue it expects to come from the development and commercialization of NBTXR3 to further advance development of the two other platforms described in the conclusion of this announcement.

“Nanobiotix has long been known for the disruptive potential of NBTXR3 for patients with cancer around the world,” said Laurent Levy, chief executive officer at Nanobiotix and chairman of the executive board. “The accomplishments we have achieved throughout our 20-year history stand as a testament to the hard work of our team, the potential value the biopharmaceutical industry at-large sees in our technology, as well as the tremendous faith and confidence our investors and other financiers hold in our vision and our management. Moreover, this global licensing agreement has us well-positioned to secure the path to market for NBTXR3—and our commitment to realize the radioenhancer’s medical and economic value remains our most important goal—but the time has also come for Nanobiotix to lead the next generation of nanoparticle-based therapies in healthcare.”

Delivering Potentially Curative Outcomes for Patients with Locally Advanced and Metastatic Cancers

NBTXR3 is being evaluated as a therapeutic candidate that could integrate into the cancer treatment paradigm for the 60% of patients with cancer who receive radiotherapy (“RT”) as part of their therapeutic regimen each year. To date, NBTXR3 has been injected in hundreds of patients by leading physicians at several pre-eminent clinical research institutions in the United States, Europe, and Asia.

The current NBTXR3 development program is initially focused on the completion of NANORAY-312, an ongoing pivotal phase 3 study evaluating the radioenhancer for elderly patients with locally advanced head and neck cancer (“LA-HNSCC”), and the launch of a randomized Phase 2 study evaluating NBTXR3 for patients with stage 3 non-small cell lung cancer (“NSCLC”) for which Janssen is fully responsible.

Preparing NANORAY-312 for Potential Regulatory Submission
In preparation for potential regulatory submission in the event of positive trial results, Nanobiotix and Janssen aligned at the collaboration’s Joint Strategy Committee (“JSC”) to transfer the global sponsorship of the Phase 3 pivotal head and neck cancer trial. Nanobiotix will continue to support Janssen in execution of NANORAY-312 during and after the sponsorship transfer is complete. Study operations will remain ongoing during the transfer.

Following discussions that began at the end of 2023, and in view of the intended transfer of the sponsorship, the JSC recently aligned to a protocol amendment that would remove the planned futility analysis in light of robust, positive final data from the expansion part of Study 102, a Phase 1 study evaluating NBTXR3 in a similar population. Given that the Study 102 results provided satisfactory support for the NANORAY-312 trial design, the futility analysis was deemed unnecessary. This amendment is subject to review and approval by health authorities in all countries where NANORAY-312 is operational as well as by the sites participating in the study. To date, the amendment has been accepted by health authorities in several major regions in the study.

Additionally, Nanobiotix and Janssen have agreed to a change in approach to the planned interim analysis such that interim data will analyzed and reported after both the requisite number of events have been observed and the last patient has been recruited in 1H2026, rather than immediately after the requisite number of events as originally planned. This revised approach helps to ensure that potentially positive trial results do not influence recruitment prior to completion of the study. As such, Nanobiotix now expects the interim analysis to be reported after the last patient is recruited in 1H2026.

“Bringing a therapeutic candidate from concept to global registration is an exciting, yet daunting proposition for any biotechnology company, even those working within well-known asset classes with well-worn development and regulatory pathways,” said Louis Kayitalire, MD, chief medical officer at Nanobiotix. “That is why our global licensing agreement with Janssen is great news for patients, for healthcare professionals, and for all other supporters of NBTXR3’s potential. We are confident that the leadership of the JSC will optimize the probability of success for NANORAY-312.”

Nanobiotix is currently vetting options for extension of the Company’s cash runway beyond the current expectation of 3Q2025.

Advancing the NBTXR3 Collaboration

Nanobiotix and Janssen have made significant progress in establishing development operations in the collaboration since execution of the global licensing agreement in July 2023.

Operational progress highlights:

• Established a JSC comprised equally of executives from both companies to drive strategic decision making for the global development program
• Activated Joint Working Teams staffed by both companies with an initial focus on manufacturing and preparing NANORAY-312 for global regulatory submission in the event of a positive interim analysis
• Began replication of Nanobiotix manufacturing processes to equip Janssen to produce NBTXR3 in parallel with ongoing production activities at Nanobiotix facilities
• Began allocation of discretionary in-kind contributions from Janssen to Nanobiotix along with payments for manufacturing technical assistance and other product development support services
• Achieved the first operational milestone in NANORAY-312, triggering a $20M milestone payment from Janssen to Nanobiotix
• Received US FDA “Study May Proceed” letter for a Janssen-led Phase 2 NSCLC study after review of the Investigational New Drug application
• Began elaboration of the overall clinical development plan for NBTXR3 including new indications beyond LA-HNSCC and stage 3 NSCLC
• Consolidated global development and commercialization rights with Janssen via the Janssen purchase of rights to China and other Asian Markets from former Nanobiotix partner LianBio

Evolving the NBTXR3 Development Pipeline

The global licensing agreement between Nanobiotix and Janssen established a framework for potential, complementary co-development of relevant indications in the near, medium, and long term. This framework includes the potential for Nanobiotix to lead new randomized Phase 2 NBTXR3 studies. The JSC will ultimately determine the next indications beyond the immediate operational priorities in LA-HNSCC and stage 3 NSCLC. Nanobiotix expects the current pipeline, as detailed below, to play an important role in the JSC decision-making process:

Nanobiotix Beyond the NBTXR3 Collaboration

As the NBTXR3 program moves toward the ultimate goal of significantly improving outcomes for patients with cancer around the world through the execution of NANORAY-312, Nanobiotix plans to expand the impact of nanoparticle-based therapies in healthcare through continued early-stage development of Curadigm and OOcuity.

The Curadigm “Nanoprimer” platform features nanoparticles designed with specific physico-chemical properties that allow temporary occupation of the liver cells responsible for therapeutic clearance. This mechanism is intended to increase the blood bioavailability and subsequent accumulation of therapeutics in the targeted tissues, potentially providing the opportunity to increase the efficacy or decrease the toxicity of intravenously-administered medicines.

The OOcuity platform is based on the principle that nanoparticle materials can interact with and influence neuronal networks via their electrical properties, this potentially enabling the modulation of malfunctioning neuronal networks toward a “normal” state. In particular, the reduction of neuronal hyper-excitability associated with neuropathic pain in in vitro studies and in mouse models with several nanoparticle candidates.

Nanobiotix expects to provide the next update on the plan and operational progress of programs beyond NBTXR3 in 2H2024.

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 physics-based 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 physics-based 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 III 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, a Johnson & Johnson company.
