PARIS and CAMBRIDGE, Mass., Nov. 13, 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 reported financial results for the third quarter of 2023.

Our robust NBTXR3 clinical program continues to demonstrate potentially transformative efficacy and well-tolerated safety across indications and patient types, including elderly and vulnerable populations. We are pleased with the encouraging, expanded potential in locally advanced pancreatic cancer supported by initial Phase 1 data from our strategic collaboration with The University of Texas MD Anderson Cancer Center (MD Anderson) presented at this year’s AACR and ESMO annual meetings,” said Laurent Levy, co-founder of Nanobiotix and chairman of the executive board. “Additionally, strong Phase 1 data from Study 102 in locally advanced head and neck cancer demonstrated high and durable activity including a 64% complete response rate, a 16.9 months mPFS and 23.1 months mOS in evaluable patients, which is nearly double the survival reported in historical data. Further, we believe the Study 102 results inform next steps and further strengthen the hypotheses underlying the design of the ongoing global, registrational NANORAY-312 Phase 3 study for NBTXR3.

Laurent Levy continued, “Building on the momentum following our recent global licensing agreement with Janssen, we have raised €50.9 million in capital that includes a public offering and the partial execution of the second equity tranche from Johnson & Johnson Innovation, Inc. With the EIB cash covenant removed, our financial overhang addressed, and our cash runway extended, we are poised to successfully execute through several important catalysts and into the expected timeframe of the NANORAY-312 interim efficacy readout.

Third Quarter 2023 Operational Highlights, Subsequent Events, and Pipeline Status and Upcoming Milestones

  • Nanobiotix announced on July 10, 2023, that it had entered into a global exclusive licensing, co-development, and commercialization agreement with Janssen Pharmaceutica NV, a Johnson & Johnson company, for the investigational, potential first-in-class radioenhancer NBTXR3. The Company has received:
    • $30 million upfront cash licensing fee (received after June 30th, 2023)
    • $5 million first equity tranche received post signing
    • $20.2 million of $25 million second equity tranche received in recent capital raise

      The Company remains eligible to receive:
    • Remaining €4.8 million from second equity tranche, subject to certain conditions
    • Up to $30M in-kind regulatory and development support for study NANORAY-312 provided at Janssen’s sole discretion 
    • Success-based payments of up to $1.8B and tiered double-digit royalties on net sales of NBTXR3 
    • Additional success-based potential development and regulatory milestone payments of up to $650 million, in the aggregate, for five new indications that may be developed by Janssen at its sole discretion 
    • And up to $220 million, in the aggregate, per indication that may be developed by Nanobiotix in alignment with Janssen
  • The Company has raised gross proceeds of €50.9 million from a recent financing and second equity tranche from Johnson & Johnson Innovation, Inc. (JJDC) extends cash runway into 2Q 2025 assuming a development milestone. Gross proceeds are expected to increase to €55.5 million following subscription by JJDC to the remaining placement amount of the second tranche of €4.6 million.

Locally Advanced Head and Neck Squamous Cell Carcinoma (LA-HNSCC): Local Control as Single Agent Activated by Radiotherapy

Third Quarter Financial Updates

Cash and Cash Equivalents

Nanobiotix reported cash and cash equivalents of €38.7 million (unaudited) as of September 30, 2023.

Based on the current operating plan and financial projections, we anticipate that the cash and cash equivalents of €38.7 million as of September 30, 2023, in conjunction with €50.9 million from the recent financing and partial execution of the second equity tranche from JJDC as well as a development milestone, extends the cash runway into the second quarter of 2025.

The gross proceeds of the Global Offering were €31.8 million including the Underwriter’s Option. Adding to this the €19.1 million gross proceeds from the restricted ADSs to be purchased by JJDC in the Concurrent Private Placement, the Company will receive aggregate gross proceeds of approximately €50.9 million (equivalent to approximately $53.8 million, based on an exchange rate of €1.00 = $1.0568, as published by Bloomberg on November 1, 2023), before deduction of underwriting commissions from the Global Offering and estimated offering expenses payable by the Company. Following the approval of the French Ministry of Economy and the subscription by JJDC for the Remaining Placement Amount, the aggregate gross proceeds would increase to approximately €55.5 million (equivalent to approximately $58.7 million) and would extend the cash runway to the end of the second quarter of 2025 (assuming the development milestone as above and excluding cash inflows from future non-dilutive or dilutive financing opportunities).

Successful Removal of the EIB Cash Covenant

As previously disclosed, the European Investment Bank (the “EIB”) has agreed to the removal of the minimum cash and cash equivalent covenant from the Company’s EIB loan, effective October 13, 2023. As result of the financing with gross proceeds of €50.9 million, the company will prepay the EIB approximately €0.5 million (1% of €50.9M) of the €20.0 million milestone payment required under the EIB loan.
