PARIS and CAMBRIDGE, Mass., Sept. 26, 2023 (GLOBE NEWSWIRE) -- NANOBIOTIX (Euronext: NANO –– NASDAQ: NBTX – the ‘‘Company’’), a late-clinical stage biotechnology company pioneering physics-based approaches to expand treatment possibilities for patients with cancer, today provided an update on operational progress and announced its half year financial results for the six-month period ended June 30, 2023.

“To date, this has been a truly transformative year for Nanobiotix following the successful execution of a global licensing, co-development and commercialization agreement for NBTXR3, the appointment of Dr. Kayitalire, an industry-veteran in oncology as CMO, and the ongoing advancement of trials designed to establish the clinical foundation of NBTXR3 in multiple solid tumor indications. Collectively, these achievements continue to propel late-stage development of NBTXR3 forward, expand our patient reach, and ultimately position us to realize the paradigm changing potential of NBTXR3 worldwide,” said Laurent Levy, co-founder of Nanobiotix and chairman of the executive board. “With our balance sheet strengthened following the upfront payment and first equity tranche from Janssen, we are poised to successfully execute across our upcoming clinical milestones. We expect topline Phase 1 escalation and expansion efficacy and safety data from study 102 in locally advanced head and neck cancer, and initial Phase 1 dose escalation safety data in pancreatic cancer from our ongoing collaboration with MD Anderson before the end of this year.”

Financial Results for the First Half of 2023

Revenue and Other Income: Revenue and other income has increased for the six months ended June 30, 2023 to €3.3 million, compared to €1.3 million for the six months ended June 30, 2022. The Company has benefited from an increase of the research tax credit of €0.6 million, granted by the French government to encourage companies to conduct technical and scientific research, and from the collaboration agreement signed with LianBio generating an additional €1.3 million revenue for the six months ended June 30, 2023.

Research and Development (“R&D”) Expenses: R&D expenses consist primarily of preclinical, clinical and manufacturing expenses related to the development of NBTXR3. These expenses for the six months ended June 30, 2023, were €17.8 million, compared to €16.6 million for the six months ended June 30, 2022. Purchases, sub-contracting and other expenses increased by €1.5 million for the six-month period ended June 30, 2023, as compared to the same period in 2022. This increase reflects the Company’s focus on advancing its clinical trial development priorities, specifically the global Phase 3 registrational trial, NANORAY-312.

Selling, General and Administrative (“SG&A”) Expenses: SG&A expenses consist primarily of administrative employee-related expenses, legal and other professional fees, patent filing and maintenance fees, and insurance. Total SG&A expenses for the six months ended June 30, 2023, were €10.9 million, compared to €9.6 million for the prior-year six-month period. Purchases, fees and other expenses increased by €1.1 million for the six-month period ended June 30, 2023 as compared to the same period in 2022, and mainly relates to €1.4 million fees paid to a financial advisor, whereas SG&A payroll cost remained stable as compared to the same period in 2022.

Net loss: Net loss attributable to common shareholders for the six months ended June 30, 2023 was €28.1 million, or €0.80 per share. This compares to a net loss attributable to common shareholders of €26.4 million, or €0.76 per share, for the same period in 2022.

Cash and Cash Equivalents: Cash and cash equivalents as of June 30, 2023, were €21.6 million, compared to €41.4 million as of December 31, 2022.

Based on the current operating plan and financial projections, we anticipate that the cash and cash equivalents of €21.6 million as of June 30, 2023, in conjunction with the $30M upfront and $5M initial equity tranche received subsequently, extents into the first quarter of 2024, which does not take into account any potential future financing, or cash inflow resulting from milestones or future collaborations. For clarity’s sake, if the EIB cash covenant would not be in place, the cash and cash equivalents would be sufficient to fund its operating expenses into the second quarter of 2024.

Subsequent to the Company’s licensing agreement executed with Janssen, the Company has entered into discussions with the EIB aiming to remove the cash covenant from the debt financing agreement between the Company and EIB. These discussions have culminated in an agreement in principle on key terms, that would result in the removal of the cash covenant in its entirety, in exchange for an acceleration of payment of a portion of the applicable Milestones Payments calculated using an escalating single digit percentage applied to bracketed funding amounts in the event of an equity funding event and the payment of scheduled PIK interest. Execution of the definitive amendment to the agreements between Nanobiotix and EIB is subject to finalization of necessary documentation and is expected at the beginning of the fourth quarter of 2023, which has the potential to positively influence our cash runway.

The Company’s executive board determined it is appropriate to prepare its half-year 2023 unaudited interim condensed consolidated financial statements on a going concern basis, assuming the Company will continue to operate for the foreseeable future, and to address its liquidity challenges by pursuing activities to generate additional cash inflows and by closely managing its operating expenditures, based on assumptions described in the half-year 2023 financial report.

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 2021, the Company announced an agreement with LianBio to expand development of NBTXR3 into Greater China and other Asian Markets, and in 2023 Nanobiotix announced a license agreement for the global co-development and commercialization of NBTXR3 with Janssen Pharmaceutica NV.
