Activity

The revenue recorded by Nanobiotix during the first quarter of 2013 corresponds to the upfront payment (pro-rata share for such quarter) received by the Company from Taiwan-based PharmaEngine, within the framework of the licensing contract. NANOBIOTIX signed the licensing contract with PharmaEngine in August 2012, for the development and marketing of its lead product, NBTXR3 in the Asia-Pacific region. The upfront payment totaled €810,640 and is apportioned using the straight-line method between the date the contract was signed and the scheduled marketing launch in the region i.e. approximately 5 years. The amount is in line with the Company’s strategy, focused on the development and marketing of NBTXR3.

NANOBIOTIX is focusing its efforts to progress clinical development of NBTXR3. The product is undergoing phase I trials in patients with advanced Soft Tissue Sarcoma (STS) at the Institut Gustave Roussy, France. NANOBIOTIX published positive interim results regarding the safety of NBTXR3 in the first group of patients in November 2012. This is an encouraging milestone in the clinical validation process of NBTXR3.

NANOBIOTIX plans to progress clinical trials of NBTXR3, and will initiate a study in head and neck cancer patients later in 2013.

The timing and progress of the clinical development of NBTXR3 are in line with the Company’s expectations and original plan at IPO.

Nanobiotix will present the therapeutic approach NanoXray and NBTXR3 clinical data to a group of oncologists and radiation oncologists. The scientific meeting will be held on June 1^st 2013 in Chicago, USA.

Next financial press release: revenue for the 2^nd quarter of 2013, on July 12, 2013
