At December 31, 2019, Sensorion operating revenue, mainly the research tax credit, amounted to €2.5m, i.e. +9.2% compared with December 31, 2018.

Operating expenses declined by 8.2%, moving down from €14.5m at December 31, 2018 to €13.3m at December 31, 2019 due to costs containment measures.

G&A expenses are up 19.0%; they amounted to some €3.1m at December 31, 2019 compared with €2.6m at December 31, 2018 in relation to the corporate support costs related to the three financial operations (lawyers, issuance fees and advisors).

Operating loss at December 31, 2019 thus came to -€10.8 m, compared with -€12.2m at December 31, 2018.

The net financial charges which increased significantly to €1.3m are mainly due to the fees related to the convertible bond operations that occurred during 2019. The costs related to setting up debts recognized at fair value (convertibles bonds) are recognized as charges in the income statement.

Net loss came to -€12.1m at December 31, 2019 quite similar level compared to last year (-€12.4m at December 31, 2018).

At December 31, 2019, the company employed 20 persons.

Key developments in 2019 and beyond

R&D

  • Launch of preclinical gene therapy programs

After initiating the strategic collaboration with Institut Pasteur, Sensorion launched the first two preclinical programs, aiming at developing gene therapies that can correct hereditary monogenic forms of deafness, specifically deafness caused by a mutation of the gene encoding for Otoferlin (OTOF) and Usher syndrome Type 1 (USH1). Sensorion selected these projects under its exclusive agreement with the Genetics and Physiology Hearing Unit at Institut Pasteur, led by Professor Christine Petit, whose laboratory has developed world-class expertise over the last 25 years in the molecular physiology and physiopathology of the hearing system and generated data supporting the development of potential gene therapies.

In addition, the French government awarded up to €9.7 millionto the "AUDINNOVE" consortium, notably including Necker Hospital, Institut Pasteur and Sensorion, to support the development of the OTOF program up to the first patient inclusion in the clinical trial.

  • Non-dilutivefunding for clinical development of SENS-401

The French government awarded non-dilutivefundingto the "PATRIOT" consortium for the clinical development of SENS-401, including work by Institut Pasteur to identify response biomarkers. The consortium includes the French Army Biomedical Research Center (IRBA), Institut Pasteur and Electronique du Mazet and the study will be the largest military trial ever conducted in France. As part of this consortium, Sensorion will receive up to €5.6 million over the duration of the project contingent on milestones completion.

  • US IND approval for SENS-401

Sensorion received Investigational New Drug (IND) approvalfrom the US Food and Drug Administration (FDA) to proceed with SENS-401 based on the preclinical data and clinical development plan package.

  • European Pediatric Investigation Plan approval for SENS-401

The European Medicines Agency (EMA) accepted a Pediatric Investigation Plan(PIP) for development of SENS-401 in the treatment of SSNHL and for prevention of ototoxicity caused by cisplatin (CIO) in the pediatric population.

  • Positive safety board review of ongoing SENS-401 Phase 2 trial

An independent Data Safety Monitoring Board (DSMB)reviewed safety data for the patients who were included in the Phase 2 trial for the treatment of SSNHL and confirmed the absence of any concern as to the safety of SENS-401 and has recommended continuing the study.

  • Results from SENS-111 Phase 2b trial in acute unilateral vestibulopathy

SENS-111 (Seliforant) was safe and well toleratedin a Phase 2 proof-of-concept study for the treatment of acute unilateral vestibulopathy (AUV). However, it did not meet the primary endpoint of vertigo intensity and Sensorion stopped all development activities for SENS-111.

  • Technological platform

Our unique R&D technological platform allows us to expand our understanding of the pathophysiology and etiology of inner ear related diseases, enabling us to select the best targets and modalities for drug candidates. We have also identified a biomarker to improve diagnosis of these underserved illnesses.

Appointment of John Furey to the Board of Directors

John Furey, former COO of Spark Therapeutics, was appointed to the Board of Directorsas independent board member. While at Spark Therapeutics, John led the successful launch of the first gene therapy in the US (LUXTURNA).

The conversion was undertaken on a price basis of €0.76 per share resulting in Invus owning 20,591,259 ordinary shares right after conversion and 35.2% of the share capital and voting rights of Sensorion (after conversion of Sofinnova Partners convertible bonds).

On the 13thof February, Sofinnova Crossover I SLP converted into ordinary shares of the company all of the 7,500,000 convertible bonds it had subscribed for in June 2019. The conversion was undertaken on a price basis of €0.76 per share resulting in Sofinnova Crossover I SLP holding 11,822,258 ordinary shares right after conversion and 20.2% of the share capital and voting rights of Sensorion.

  • Ethics Committee approval to include new military sites in SENS-401 Phase 2 study

Sensorion hasreceived approval from the Independent Ethics Committee of Strasbourg (France)to include new military sites in the ongoing Phase 2 study of SENS-401in SSNHL. The new centers will recruit volunteer military personnel exposed to impulse noise during their professional activities and suffering from hearing loss. Inclusion of voluntary military patients on these new sites will start after final administrative steps are carried out.

  • Appointment of new Chief Medical Officer

Sensorion appointed gene therapy expertGéraldine Honnet MD, as Chief Medical Officer (CMO).Géraldine Honnet is a medical doctor and joins from Généthon, where she spent nine years as Chief Medical Officer, overseeing international gene therapy clinical trials in multiple rare diseases. Géraldine was responsible for the development of Généthon pipeline from pre-clinicalto registration, managing Medical Affairs, Clinical Development, Clinical Operations and Regulatory affairs departments.

  • Update on SENS-401 Phase 2 trial enrollment

On the 13th of March, Sensorionmade an update on timelines for the ongoing Phase 2 studyof SENS-401to treat Sudden Sensorineural Hearing Loss (SSNHL). Patient recruitment rates from this trial now indicate the data will be available by mid-year2021, which is later than previously announced. The AUDIBLE-Strial is progressing but at a slower pace than our original expectations. An important factor also impacting recruitment in our trial is the repriorization of emergency room resources due to the current COVID-19situation.

Upcoming clinical and preclinical milestones

  • Interim preclinical data on SENS-401 to preserve hearing after cochlear implantation by mid-year 2020; full preclinical data package by year end 2020
  • Preclinical milestones for OTOF and USH1 by mid-year 2020
  • Phase 2 data for SENS-401 in Sudden Sensorineural Hearing Loss (SSNHL) by mid-year 2021

Press release

Outlook for 2020 and COVID-19 situation update

Sensorion will keep advancing development of SENS-401 which is at clinical stage as well as pursuing research work using its R&D platform. Results from the Phase 2 of SENS-401 in Sudden Sensorineural Hearing Loss are expected by mid-year 2021. Preclinical data of SENS-401 in collaboration with Cochlear for preservation of hearing after cochlear implantation as well as preclinical milestones from the two gene therapy programs are expected this year.

Sensorion is closely monitoring the COVID-19 epidemic situation as well as its potential impact on activities of the company.

At this stage we are observing an impact on the SENS-401 phase 2 trial due to the repriorization of emergency room resources and confinement of populations. In order to avoid overload of healthcare facilities, to ensure safety of new potential patients, to prevent major protocol deviations due to non-respect of follow-up visits as planned in the protocol and to minimize contact between patients and investigational staff, the recruitment of new patients in the study has been temporarily suspended.

Regarding patients being in the study, there is a risk that it might be impossible for some of them to complete the follow-up visits as planned in the protocol of the study. Follow-up visits are being planned through teleconference or videoconference with the clinical sites with help from the clinical research organization working with Sensorion on this study. The current situation also poses a risk of delay in the opening of the new military sites that will recruit patients in the ongoing phase 2 trial of SENS-401 for sudden sensorineural hearing loss.

It's difficult to determine the evolution of the epidemic situation but there is a risk that it might cause delay in the realization of preclinical gene therapy studies carried out within the collaboration with Institut Pasteur. This would delay the preclinical results expected for the two ongoing programs.

As recommended by the French government, all the employees at Sensorion for which remote working is possible are effectively remotely working. For ethical reasons, an ongoing animal study with SENS-401 is continued with involvement of 3 employees alternating presence on site. This study is scheduled to end in April 2020 and no further animal study will be initiated before a favorable evolution of the epidemic context.
