Nanobiotix Expands Its Clinical Development In Head And Neck Cancer And I/O

NANOBIOTIX EXPANDS ITS CLINICAL DEVELOPMENT IN HEAD AND NECK CANCER AND IMMUNO-ONCOLOGY
NEW CLINICAL DATA TO BE PRESENTED AT ASCO

Paris, France and Cambridge, Massachusetts, April 4, 2017 - NANOBIOTIX (Euronext: NANO - ISIN: FR0011341205), a late clinical-stage nanomedicine company pioneering new approaches to the treatment of cancer, today announced the expansion and acceleration of its clinical development activities. These include:

• Acceleration of the head and neck cancer program. Phase I/II data will be presented at ASCO in June
• Expansion of Nanobiotix’s Immuno-Oncology program into patients focused on the objective of turning cold tumors into hot tumors. Nanobiotix will present the first clinical data from this program mid year

NBTXR3: New programs and upcoming data

Presentation of the Phase I/II data of Nanobiotix’s European head and neck trial with NBTXR3 at the American Society of Clinical Oncology (ASCO) Annual Meeting in June. Nanobiotix is preparing the next clinical trials of the head and neck cancer program. Based on the value of the data to be presented in June, the Company will determine the fastest pathway to the U.S. and European markets.

Presentation of the first clinical data from Nanobiotix’s new clinical program in Immuno-Oncology mid year. Based on the preclinical proof of concept presented in November 2016 at the Society for Immunotherapy of Cancer (SITC), Nanobiotix initiated an exploratory clinical biomarkers study in soft tissue sarcoma patients (data from Nanobiotix’s phase II/III trial in soft tissues sarcoma). This trial investigates whether NBTXR3 could play a role in Immuno-Oncology by turning cold tumors into hot tumors (compared with radiotherapy alone).

Ongoing activities

Continuation of the Phase II/III trial in soft tissue sarcoma with NBTXR3, recommended by an Independent Data Monitoring Committee (IDMC), which evaluated the safety and efficacy data of two thirds of the patients in the “Act.in.Sarc” study. As planned and communicated, the completion of the patient recruitment process for this trial is expected by the end of Q2 2017, with data, except for long-term follow-up, expected by the end of 2017.

Nanobiotix will continue to develop NBTXR3 in other indications: These include prostate cancer (Phase I/II), liver cancers (Hepatocellular Phase I/II and liver cancer metastases Phase I/II), rectum cancer (Phase I/II - by PharmaEngine) and head and neck cancers in patients receiving chemotherapy (Phase I/II - by PharmaEngine). In H2 2017, the prostate cancer indication should deliver preliminary safety and feasibility data. Additionally, before the end of 2017, Nanobiotix aims to complete patient recruitment for the Phase I part in liver cancers, and may proceed to select the patient population for the dose-expansion part of the trial (Phase II).

In parallel, Nanobiotix is accelerating its market preparations for NBTXR3’s launch on the European market. The first approval (CE marking) in Europe is expected in H2 2017.

The Company’s first-in-class, proprietary technology, NanoXray, enhances radiotherapy energy with a view to provide a new, more efficient treatment for cancer patients.

NanoXray products are compatible with current radiotherapy treatments and are meant to treat potentially a wide variety of solid tumors including soft tissue sarcoma, head and neck cancers, liver cancers, prostate cancer, breast cancer, glioblastoma, etc., via multiple routes of administration.

NBTXR3 is being evaluated in: soft tissue sarcoma (STS), head and neck cancers, prostate cancer, and liver cancers (primary and metastases). Additionally, head and neck cancer and rectal cancer trials led by Nanobiotix’s Taiwanese partner, PharmaEngine, are underway in the Asia Pacific region. The Company has filed in August 2016 for market approval (CE Marking) in Europe for its lead product NBTXR3.

The Company started in 2016 a new preclinical research program in Immuno-oncology with its lead product NBTXR3, which could have the potential to bring a new dimension to cancer immunotherapies.
