Montpellier, January 28, 2026, 7.30am CET – Sensorion (FR0012596468 – ALSEN) a pioneering clinical-stage biotechnology company which specializes in the development of novel therapies to restore, treat and prevent hearing loss disorders, today announced a €60 million offering reserved to specific categories of investors (the “Reserved Offering”) through the issuance of 214,285,714 new ordinary shares of the Company (the “New Shares”) at a price per New Share of €0.28 (the “Subscription Price”) to the benefit of Sanofi for €20 million, and Redmile Group, Artal, which is advised by Invus, and Sofinnova Partners, existing shareholders, and other investors including Cormorant Asset Management, Coastlands Capital and Sphera Healthcare, for €40 million. The settlement-delivery of the Reserved Offering is expected to take place around January 30th, 2026, subject to customary conditions.
Sanofi’s investment and participating investors will drive the progression of the genetic medicine pipeline, notably SENS-601 (GJB2-GT). This funding supports key catalysts for the program which targets hearing loss associated with GJB2 mutations, including CTA/IND approval and the enrollment of the first clinical cohort.
SENS-601 (GJB2-GT) will be the Company’s second gene therapy program to enter the clinic, following SENS-501, which entered clinical development in 2024. The program targets GJB2 mutations, which are responsible for a significantly larger patient population, accounting for approximately 50% of autosomal recessive non-syndromic congenital hearing loss and implicated in early-onset forms of severe presbycusis in adults.
Nawal Ouzren, Chief Executive Officer of Sensorion, said: “We welcome Sanofi’s new strategic investment in Sensorion to advance our pipeline of innovative therapies intended to improve the quality of life of patients suffering from hearing disorders. We are very thankful to the top-tier new investors who joined us and express our gratitude to our existing shareholders who have reaffirmed their support in this transaction. With the additional capital, the Company plans to intensify the ongoing efforts to progress the research and development of SENS-601, including the advancement of the program into its clinical development, and to continue the clinical development of SENS-501 program. This marks an important milestone for the Company’s corporate growth trajectory and for patients suffering from a variety of hearing loss disorders.”
Expected next clinical milestones
- Q1 2026 – SENS-501: Cohort two 6-months follow-up data of Phase 1/2 Audiogene trial
- Q1 2026 – SENS-401 in Cisplatin-induced Ototoxicity: Notoxis Phase 2a data readout
- Q1 2026 – SENS-601 (GJB2-GT): Clinical Trial Application Submission
Impact on cash flow and use of proceeds

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 the diagnosis of these underserved illnesses.
Sensorion’s portfolio also comprises programs of a clinical-stage small molecule, SENS-401 (Arazasetron), for the treatment and prevention of hearing loss disorders. Sensorion’s small molecule progressed in three Phase 2 proof of concept clinical study: firstly, in Cisplatin-Induced Ototoxicity (CIO) for the preservation of residual hearing, for which the recruitment is completed, and the follow-up is ongoing. Secondly, with partner Cochlear Limited, a study of SENS-401 for the residual hearing preservation in patients scheduled for cochlear implantation, completed in 2024. Thirdly, a Phase 2 study of SENS-401 was also completed in Sudden Sensorineural Hearing Loss (SSNHL) in 2022.
