First-half 2019 financial results

The half-year accounts at June 30 2019, drawn up according to IFRS standards and approved by the Board of Directors on October 30 2019, have been duly reviewed by statutory auditors.

The simplified income statement at June 30 2019 is as follows:

In Euros –IFRS standards	31.06.2019	31.06.2018
Operating income	1,042,407	1,299,199
Research and Development expenses	5,226,883	5,849,636
General and Administrative expenses	1,257,185	1,542,860
Total operating expenses	6,484,068	7,392,496
Operating profit/loss	-5,441,662	-6,093,297
Financial profit/loss	-22,929	-45,186
Net profit/loss	-5,464,591	-6,138,483

At June 30 2019, Sensorion operating income, mainly the research tax credit, amounted to €1.04m, compared to €1.29m at June 30 2018.

Operating expenses fell 12%, down from €7.4m at June 30 2018 to €6.5m at June 30 2019, mainly owing to a 20% reduction in G&A expenses and a 10% reduction in research costs. The research platform costs have been reduced while the costs of the SENS-111 clinical study have remained stable; costs for the SENS-401 clinical trial are ramping up slowly.

G&A expenses fell 20% to €1.3m at June 30 2019, compared with €1.5m at June 30 2018, reflecting the company's determination to cut costs in all areas.

Operating loss at June 30 2019 thus amounted to -€5.4m, compared with -€6.09m at June 30 2018.

Net loss amounted to -€5.5m at June 30 2019, compared with -€6.1m at June 30 2018.

At June 30 2019, the company employed 18 people.

Financial structure

On March 11th 2019, Sensorion undertook a bond issue of a nominal amount of €4.7m with European financial investors, consisting of (i) a convertible bond issue for a nominal €3.4m underwritten by several new European investors, plus (ii) a simple bond issue of a nominal €1.3m. 4,408,606 bonds have been converted into 4,398,176 shares during the first half.

Equity capital amounted to €2.3m at June 30 2019, compared with €3.5m euros at June 30 2018.

Invus and Sofinnova Crossover I SLP invested in Sensorion as long-term partners on June 12, 2019 via a mandatory convertible bond issue for a nominal amount of €20m. They have taken three seats on the board of directors (two for Invus, one for Sofinnova), and are subject to a lock-up till June 30, 2020. These bonds will undergo compulsory conversion into shares at the latest on the maturity date (June 13, 2024) and do not bear interest.

Current liabilities include €19.1m of convertible bonds at June 30 2019.

At June 30 2019, cash and cash equivalents amounted to €22.3m compared with €2.7m at December 31 2018, thanks to the injection of funds stemming from the convertible bond issues.

Key developments: Research & Development and scientific communications

Collaboration with Institut Pasteur in Gene Therapy programs targeting hearing loss

On May 27 2019, Sensorion announced the signature with Institut Pasteur (Paris) of a framework agreement for a research partnership granting Sensorion an exclusive option to an exclusive license in order to develop and commercialise drug candidates in gene therapy for the restoration, treatment and prevention of hearing problems.

In the first place, Sensorion has launched two preclinical gene therapy programs targeting the Usher Syndrome type 1 and the Otoferlin-deficiency, two monogenic forms of hereditary deafness. On top of these programs, part of the framework agreement signed with Institut Pasteur, other projects could emerge in the same domain of genetic forms of deafness. During the five years of the partnership, Sensorion also has a preference right on all Institut Pasteur programs research in the domain of genetic diseases of the inner ear to implement collaborations leading to a license. These programs are conducted under the sponsorship of Professor Christine Petit, director of "L'Institut de l'Audition" and Chair of our Scientific Advisory Board.

Moreover, the specific gene therapy program aimed at correcting a hereditary monogenic form of deafness caused by a mutation of the gene encoding for Otoferlin (DNBF9) was retained on June 10 2019 in the RHU call for healthcare projects in the "Avenir" public investment program. The "AUDINNOVE" project which is conducted by the ENT department of Hospital AP-HP-NECKER, is an association that includes Institut Pasteur, "La Fondation pour l'Audition" and Sensorion as the industrial partner. This project received €9.7m as a grant, with payment in stages over the development period of the program.

Drug candidate SENS-111: Enrolment of the patients completed in the phase 2b proof of concept

Sensorion has undertaken phase 2 clinical trials with SENS-111 in acute unilateral vestibulopathy (AUV). AUV was chosen as a first indication to demonstrate proof-of-concept as it is a pure disease for which the patient phenotype is quite homogeneous. Two phase 2 were conducted in 2018:

• Positive results of the first one were published in December 2018 confirming the initial hypothesis whereby the SENS-111 drug candidate impacts negatively neither the vigilance nor the cognitive performance of patients during a motion stimulus. The trial also showed that SENS-111, in contrast to meclizine, has no negative CNS (Central Nervous System) side effects such as sedation, impairment of memory and of cognitive performance
• As for the second phase 2b proof of concept, the 105 expected patients have been recruited. We announced that the last visit of the last patient took place on October 15, 2019. Efficacy data will be known by the end of the second half of 2019. This information will enable Sensorion to present a strong data package covering the scientific, clinical and commercial advantages of SENS-111 to potential partners.

Drug candidate SENS-401: Clinical study progressing - Paediatric Plan authorized in two indications

The SENS-401 phase 2 clinical trial in the treatment of sudden sensorineural hearing loss in adults (SSNHL) has been launched. This randomized, double-blind and placebo-controlled phase 2 trial will unfold in 12 countries to recruit some 260 patients. It has gradually started in some fifteen sites in Europe and Canada. Interim safety data are expected at the end of the second half of 2019 and the final results of the clinical trial are expected at the end of the first half of 2020.

On June 28 2019, the European Drug Agency (EMA) accepted SENS-401 paediatric investigation plan (PIP) for both the development of the treatment of sudden hearing loss (SSNHL) and prevention of cisplatin-induced ototoxicity (CIO) in the paediatric population. This agreement is necessary for an application for a marketing authorisation in Europe.

Technology platform

The company is accelerating with the development and utilisation of its specialised screening platform in all inner ear pathologies. We continue our collaboration with renowned international experts for the validation of translational, quantitative endpoint measures in tinnitus. We have also implemented robust models of chronic noise exposure and age-related hearing loss.

Regular scientific communication

During the first half, Sensorion made presentations at various scientific congresses and notably:

• The results presented to the ARO MidWinter Meeting in February 2019 via two posters which showed proof of efficacy for SENS-401 in preclinical models. The first poster showed the lasting protection by SENS-401 of cochlear cilia cells for Organ of Corti explants in culture, after ototoxicity induced by gentamicin. And the second showed that a targeted local exposure to SENS 401 is not specific to a single species and the otoprotective efficacy can be generalised, the PK/PD models can thus be translated.
• The SENS-111 development program was exposed at the 'European Histamine Research Society' in Krakow in Poland. The translational development of Seliforant (i.e. SENS-111) was presented from the results of the preclinical models in vitro and in vivo up till the proof of concept (POC) validation phase.
• A presentation of the SENS-111 phase 2 trial protocol in acute unilateral vestibulopathy (AUV) was made during the symposium of the Société Internationale d'Otoneurologie in Venice in June.

Capital breakdown after the September 2019 capital increase

Sensorion's financial position strengthened further on end of September 2019 following a €18.1m capital increase with a 12% premium on last price, underwritten by first-tier investors. The completion of this capital increase was supported by Invus, Sofinnova Crossover I SLP and new investors including WuXi AppTec and 3SBio. The participation of Invus, Sofinnova Crossover I SLP and Marijn Dekkers in this financing round demonstrates their continued support in the Company's long-term strategy. The relationship with 3SBio will help us build a commercial strategy for the China region.

The breakdown of the company's capital at September 26th, 2019 is described in the table thereafter. The last two columns include the impact of any conversion of the entirety of the convertible bonds issued in March and June 2019.
