On this occasion, Sensorion will host a symposium on September 20, 2024, at 12.30pm CET, entitled:

“Are we at the Dawn of a Hearing Loss Revolution?”

This event will be hosted by Professor Natalie Loundon ENT Surgeon in the pediatric Hospital Necker-Enfants malades in Paris, France. The symposium will comprise three sessions:

• 1^st Session: Hearing Preservation: Relevant Medical Progress in Cisplatin-Induced Ototoxicity and the Loss of the Residual Hearing following Cochlear Implantation

This session will focus on the therapeutic advances in hearing preservation associated with Cisplatin-Induced Ototoxicity and following cochlear implantation. Professor Yann Nguyen (ENT Surgeon, Hôpital de la Pitié Salpêtrière, Paris, France) and Professor Stephen O'Leary (Head of Otolaryngology at the University of Melbourne, Melbourne, Australia) will co-present this session.

• 2^nd Session: Gene therapy: A Ray of Hope for Congenital Hearing Disorders

This session will address gene therapy applied to patients suffering from congenital profound deafness and will be presented by Professor Catherine Birman (Otorhinolaryngologist, Director of the Sydney Cochlear Implant Centre, Sydney, Australia).

• 3^rd Session: Conclusion: What Does the Future Hold for these New Therapies?

This session will be led by Professor Natalie Loundon (Pediatric otorhinolaryngologist, Director of the Cochlear Implant and Audiology Unit, Necker-Enfants malades, Paris, France) and will address the impact these new therapies will have on patient management, followed by a question-and-answer session.

About Sensorion

Sensorion is a pioneering clinical-stage biotech company, which specializes in the development of novel therapies to restore, treat, and prevent hearing loss disorders, a significant global unmet medical need. Sensorion has built a unique R&D technology platform to expand its understanding of the pathophysiology and etiology of inner ear related diseases, enabling it to select the best targets and mechanisms of action for drug candidates.

It has two gene therapy programs aimed at correcting hereditary monogenic forms of deafness, developed in the framework of its broad strategic collaboration focused on the genetics of hearing with the Institut Pasteur. SENS-501 (OTOF-GT) currently being developed in a Phase 1/2 clinical trial, targets deafness caused by mutations of the gene encoding for otoferlin and GJB2-GT targets hearing loss related to mutations in GJB2 gene to potentially address important hearing loss segments in adults and children. The Company is also working on the identification of biomarkers to improve diagnosis of these underserved illnesses.

Sensorion’s portfolio also comprises clinical-stage small molecule programs for the treatment and prevention of hearing loss disorders. Sensorion’s clinical-stage portfolio includes one Phase 2 product: SENS-401 (Arazasetron) progressing in a planned Phase 2 proof of concept clinical study of SENS-401 in Cisplatin-Induced Ototoxicity (CIO) and, with partner Cochlear Limited, in a study of SENS-401 in patients scheduled for cochlear implantation. A Phase 2 study of SENS-401 was also completed in Sudden Sensorineural Hearing Loss (SSNHL) in January 2022.
