After the achievement of major development milestones in 2019, 2020 offers great opportunity for Nanobiotix and NBTXR3 to fulfill unmet patient needs across oncology. Given NBTXR3s universal mode of action, our proof-of-concept in soft tissue sarcoma, and promising results from our phase I trial in head and neck cancers, we are confident that NBTXR3 activated by radiation therapy has the potential to significantly improve treatment outcomes for head and neck cancer patients. Beyond head and neck, we will continue to expand into additional indications and combination therapies. Ultimately, we aim to change the oncology treatment paradigm for millions of patients around the world. Laurent Levy, CEO of Nanobiotix

NANOBIOTIX (Euronext : NANO ISIN : FR0011341205 the Company) today announced its global development strategy for 2020 and beyond, following proof-of-concept (POC) and European market approval for NBTXR3 in locally advanced soft tissue sarcoma of the extremities and trunk wall (Brand Name: Hensify) in 2019. The Company will continue to prioritize its registration pathway in the US and EU for the treatment of head and neck cancers, while also working to advance the Nanobiotix immuno-oncology (I/O) program and evaluate NBTXR3 in other indications such as lung, pancreatic, esophageal, hepatocellular carcinoma (HCC), prostrate, and rectal cancers. To execute this plan, Nanobiotix will focus on H&N cancers while its collaborators (i.e. The University of Texas MD Anderson Cancer Center (MD Anderson) in the US and PharmaEngine in Asia) are working on other indications.

Development in Head and Neck Moving Forward

There are approximately 700,000 new head and neck cancer patients worldwide each year300,000 of these patients reside in the US and the European Union (EU) 1. Of these patients at diagnosis, 90% suffer from local disease and the remaining 10% have metastatic disease. 70-80% of all Head and Neck patients will receive radiation therapy, but significant unmet medical needs remain regarding either local control, systemic control, toxicity, or some combination of the three2. This is especially challenging for patients ineligible for platinum-based chemotherapy (cisplatin).

Global Registration Trial for NBTXR3 in Head and Neck Patients Ineligible for Cisplatin

As previously announced, Nanobiotix has begun interacting with the US Food and Drug Administration (FDA) on its regulatory pathway and met with the agency in October 2019 to refine the design elements of Study 312a phase III investigators choice, dual-arm, randomized (1:1) global registration trial including elderly head and neck cancer patients who are ineligible for platinum-based chemotherapy (cisplatin).

More than half of head and neck cancers include large primary tumors which may invade underlying structures and/or spread to regional nodes. Treatment of these locally advanced forms of the disease ordinarily requires aggressive, concerted measures. Due to potential comorbidities and toxicities associated with treatment, elderly and frail patients suffer from limited therapeutic options. Study 312 aims to target the unmet needs of this population.

Patients in the control arm will receive radiation therapy with or without cetuximab (investigators choice), and patients in the treatment arm will receive NBTXR3 activated by radiation therapy with or without cetuximab (investigators choice). The trial will recruit around 500 patients, the initial readout will be based on event-driven progression-free survival (PFS), and the final readout will be based on PFS and overall survival (OS). The study will be powered to demonstrate the OS superiority of NBTXR3 activated by radiation therapy. In addition, quality of life (QoL) will be measured as a key secondary outcome.

The Companys next step is to submit the final trial design to FDA and other global regulatory bodies within the month. A futility analysis is expected 18 months after the first patient is randomized, the interim analysis for PFS superiority is expected at 24-30 months, and final analysis will report on PFS and OS. In the event of favorable data from the initial readout, Nanobiotix plans to apply for conditional registration in the US.

Confirming Efficacy with Phase I (Study 102) Expansion

Nanobiotix has already reported promising early signs of efficacy for patients with head and neck cancer through Study 1023 a phase I trial of NBTXR3 nanoparticles activated by intensity-modulated radiation therapy (IMRT) in the treatment of advanced-stage head and neck squamous cell carcinoma (HNSCC). The patient population for Study 102 includes elderly and frail patients who are ineligible for cisplatin or intolerant to cetuximab.

As a result of this report, the Company launched an expansion cohort with 44 additional patients to strengthen preliminary efficacy data. Recruitment for the expansion cohort has reached 38 of 44 patients and the initial readout is expected by mid-2020. Depending on the favorability of the final expansion phase data, the Company may seek to expedite the regulatory process in the EU.

Additional Development in Head and Neck with Collaborators

To serve as many head and neck cancer patients as possible and as mentioned above, the Company has engaged in ongoing clinical collaborations with MD Anderson in the US and PharmaEngine in Asia.

The Company is collaborating with MD Anderson on nine (9) clinical trials across multiple indications, three (3) of which are expected to evaluate head and neck cancer in patient populations outside of the trials Nanobiotix is executing alone (e.g. borderline resectable, inoperable and neck cancer (re-irradiation), etc.)
