Onxeo Reports First-Half 2017 Results and Business Update

Regulatory News:

Onxeo S.A. (Paris:ONXEO) (NASDAQ OMX:ONXEO) (Euronext Paris, NASDAQ Copenhagen: ONXEO), a clinical-stage biotechnology company specializing in the development of innovative drugs for the treatment of orphan diseases, in particular in oncology, today reported its consolidated half-year financials to June 30, 2017, and provided an update on the key achievements over the first six months of the year as well as its recent developments.

"The first half of 2017 was marked by a strong momentum in all areas of Onxeo’s activity. First of all, we completed, on schedule, the enrollment for our ReLive trial in the treatment of primary liver cancer with Livatag®, our most-advanced drug candidate. The DSMB¹ of ReLive delivered its 10^th unanimous positive recommendation to continue the trial, thus confirming the compound’s acceptable tolerance profile, and we’re now expecting the preliminary efficacy results before the end of September. Over the half year, we continued the exploratory preclinical program with Beleodaq® in other indications or combinations, with first results expected at the end of the third quarter of 2017. Our most significant scientific achievement so far this year was the preclinical proof of concept of AsiDNA™ activity via intravenous administration, thereby considerably expanding its potential. These robust preclinical data provide a solid foundation from which to advance this first-in-class DNA repair inhibitor towards clinical development. Last but not least, from a financial perspective, we successfully completed a €15m private placement with prominent US and European investors who showed a keen interest in supporting the ramp-up in our strategic programs,” said Judith Greciet, CEO of Onxeo.

H1 2017 CONSOLIDATED FINANCIAL STATEMENT

Financial statements have been subject to a limited review by the Company’s statutory auditors.

¹ The Data Safety Monitoring Board is a Committee of independent European experts in charge of the blind review of the trial tolerance data.

Revenues for the first half of 2017 increased by 79% to €3.4 million and consisted of:

• €1.9m in recurring revenue resulting from the sale of products to Onxeo’s commercial partners and royalties on sales.
• €1.5 in non-recurring revenue, the significant increase compared to the first half of 2016 corresponding essentially to the phased IFRS recognition of the initial payment associated with the exclusive license agreement signed with Pint Pharma in 2016.

Operating expenses stood at €14.7 million for H1 2017, a 12.5% increase compared to the same period in 2016, due to the deployment of R&D activities. This included notably the launch of the AsiDNA™ industrial and preclinical programs, acquired in March 2016, for which the Company has set up an ambition development plan. In addition, the Company has continued its phase III clinical trial with Livatag®, and has also continued its preclinical development program for Beleodaq®. In parallel, a tight control has been maintained over other operating expenses in order to optimize the company’s cash burn.

Financial income was mainly impacted by exchange rate variances resulting from the company’s operations as well as its assets denominated in foreign currency.

All in all, the net loss for the semester was comparable to last year.

SOUND CASH POSITION OF €27.7 MILLION

At June 30, 2017, the Company had a sound consolidated cash position of €27.7 million, including gross proceeds of €15 million from the capital increase resulting from the late June 2017 private placement with US and European investors. Taking into account the €3.9 million reimbursement of 2016 Research Tax Credit expected in 2017, Onxeo’s cash runway extends up to Q1 2019.
