Income statement

Activity

There has been no revenue booked during the first quarter of 2017 since in particular i) the upfront payment from the licensing contract signed with PharmaEngine in August 2012 has been fully recognized last year (pro-rata share recognized from August 2012 until December 2016), as per Company's accounting processes, and ii) the Company had no services activities with its partners during the first quarter of 2017, in line with planned operations.

In March 2017, Nanobiotix announced that the Independent Data Monitoring Committee (IDMC) recommended the continuation of the ongoing phase II/III trial of NBTXR3 in Soft Tissue Sarcoma (Act.in.sarc study), based on the safety and efficacy data.

The interim evaluation was based on an analysis of the results of two-thirds of the patients included in the Phase II/III study - 104 patients were analyzed out of a total of 156. The completion of recruitment is planned by the end of Q2 2017 and the full data is expected by the end of 2017.

Nanobiotix also announced in March 2017, the presentation of NBTXR3 preclinical studies demonstrating 1) the antitumor efficacy of NBTXR3 in five different in vivo human cancer models and 2) the antitumor efficacy of NBTXR3 in combination with chemotherapy, in both in vitro and in vivo studies. These data have been presented at the American Association for Cancer Research (AACR) Annual Meeting 2017 in Washington, D.C (April 1-5, 2017).

Finally, beginning of 2017, Nanobiotix appointed Alain Dostie, a senior executive from the pharmaceutical industry, as its Chief Operating Officer (COO) to oversee operations and product commercialization.
