Release Details

Paris, France ; Cambridge, Massachusetts (USA) ; March 4, 2021 – NANOBIOTIX (Euronext : NANO –– NASDAQ: NBTX – the ‘‘Company’’), a clinical-stage biotechnology company pioneering physics-based approaches to expand treatment possibilities for patients with cancer, today announced that the Company has reached an agreement with PharmaEngine, Inc. (“PharmaEngine”) to terminate the License and Collaboration agreement that the Company and PharmaEngine entered into in August 2012.

As previously disclosed in the Nanobiotix prospectus filed with the U.S. Securities and Exchange Commission on December 11, 2020, in November 2020, Nanobiotix notified PharmaEngine of a material breach of the terms of the License and Collaboration agreement. In a letter dated December 1, 2020, PharmaEngine responded to the Company’s notification of material breach, denying a material breach of the License and Collaboration agreement, and asserting certain material breaches of that agreement by Nanobiotix. After discussion between the two parties, this agreement to terminate the License and Collaboration agreement represents a full resolution of outstanding disagreements over a number of issues with respect to the development of NBTXR3 in the Asia-Pacific region.

The License and Collaboration agreement provided PharmaEngine exclusive rights to further the development of NBTXR3 in the Asia-Pacific region. While both Nanobiotix and PharmaEngine believe in the potential of NBTXR3 to improve treatment outcomes for patients with cancer, the parties have had disagreements regarding the optimal strategy for development in the Asia-Pacific region. As such, Nanobiotix and PharmaEngine have mutually agreed to discontinue the collaboration.

Pursuant to their Termination and Release agreement, Nanobiotix will retain all rights to the development and commercialization of NBTXR3 in the Asia-Pacific region. PharmaEngine is to receive payments, not to exceed $5 million in total, upon the completion of various administrative steps in connection with the winding-up of the collaboration.

In the future, PharmaEngine will be entitled to receive a payment of $7.5 million upon a second regulatory approval of NBTXR3 in any jurisdiction of the world for any indication, unless the Company announces a collaboration with a new partner for the Asia-Pacific region within 6 months of the effective date of the agreement. If that occurs, PharmaEngine will be entitled to an immediate $2.5 million payment and will be eligible to receive a payment of the remaining $5 million upon such second regulatory approval of an NBTXR3-containing product. The Company has also agreed to pay royalties to PharmaEngine at low-single digit royalty rates with respect to sales of NBTXR3 in the Asia-Pacific region for a 10-year period commencing on the corresponding first date of sales in the region.

Retention of all rights regarding NBTXR3 will open new near- and long-term possibilities for the Company, and Nanobiotix will evaluate the Asia-Pacific region for potential inclusion in its upcoming global phase III registration trial in head and neck cancer.
