Sensorion Announces Approval To Initiate Lead Gene Therapy Candidate SENS-501 (OTOF-GT) Into A Phase 1/2 Clinical Trial In Some European Countries

Sensorion

Sensorion (FR0012596468 – ALSEN) a pioneering clinical-stage biotechnology firm which specializes within the improvement of novel therapies to revive, deal with and forestall inside the discipline of listening to problems, at the moment pronounces that it has obtained approval for its Scientific Trial Software (CTA) to provoke a Section 1/2 medical trial of SENS-501 (OTOF-GT), in France. The conclusion of the Half I of the evaluation report in line with regulation EU 536/2014 overlaying France, Italy and Germany is that the conduct of the medical trial is suitable.

The part 1/2 medical trial (Audiogene) goals to judge the security, tolerability, and efficacy of intra-cochlear injection of SENS-501 for the remedy of OTOF gene-mediated listening to impairment in paediatric sufferers aged 6 to 31 months on the time of gene remedy remedy. Focusing on the primary years of life, the time interval when the auditory system plasticity is perfect, will maximize the possibilities of these younger kids with pre-lingual listening to loss to accumulate regular speech and language. Audiogene may also assess the medical security, efficiency, and value of the administration machine system below improvement in partnership with EVEON. The design of the examine will encompass two cohorts of two doses adopted by an growth cohort on the chosen dose. Whereas the security would be the main endpoint for the dose escalation cohort , the auditory brainstem response (ABR) would be the main efficacy endpoint of the dose growth cohort. The CTA approval follows in depth preclinical research assessing the security and efficacy of SENS-501 and profitable manufacturing of the gene remedy Drug Product for the medical trial. Sensorion will talk concerning the first affected person in the middle of H2 2024.

Nawal Ouzren, Sensorion’s Chief Govt Officer, stated: “Securing approval to start out the part 1/2 medical trial for SENS-501 marks a major milestone for Sensorion and confirms our place of a number one firm within the rising discipline of gene therapies for listening to loss. Listening to loss attributable to mutations of the gene encoding for otoferlin is a difficult dysfunction and there are not any accepted healing therapies for youngsters with congenital deafness, so it is a vital unmet medical want. We stay up for persevering with to work with healthcare suppliers, regulatory authorities, affected person teams to deal with unmet and underserved medical wants within the listening to area.”

Professor Natalie Loundon, M.D., Director of the Heart for Analysis in Pediatric Audiology, Pediatric Otolaryngologist and Head and Neck Surgeon, Necker Enfants Malades, AP-HP, in Paris, France, Coordinating Investigator of the Audiogene medical examine, commented: “SENS-501 represents a hope for quite a few kids born with deafness linked to a defect within the otoferlin gene and for whom no healing remedy exists at the moment. The administration of a single-injection remedy to very younger kids requires state-of-the-art hospital technical platform and well being care givers workforce acquainted with the dealing with of gene therapies. In step with our philosophy of supporting innovation wherever kids’s medical wants go unmet, we’re delighted to be totally concerned from the very starting on this pioneering medical trial.”

Sensorion’s SENS-501 (OTOF-GT) twin vector AAV gene remedy improvement program goals to revive listening to in sufferers with mutations within the gene coding for otoferlin protein that suffer from extreme to profound sensorineural prelingual non-syndromic listening to loss. Sensorion’s lead gene remedy program has been developed as a part of its collaboration targeted on the genetics of listening to with the Institut Pasteur, which has been initiated in 2019.

The Genetics and Physiology of the Listening to Unit of the Institut Pasteur, led by Professor Christine Petit, MD, PhD, has developed world-class experience during the last 25 years within the molecular physiology and physiopathology of the listening to system. Current advances, carried out alongside Saaid Safieddine, PhD, have led to the event of the gene remedy product SENS-501.

Professor Christine Petit, Professor on the Institut Pasteur and Professor Emeritus on the Collège de France, France, Winner of the Kavli Prize in 2018, commented: “This regulatory inexperienced gentle for the inclusion of sufferers in France in one of many world’s first gene remedy trials within the discipline of listening to represents a serious achievement for the groups on the Institut de l’Audition (Institut Pasteur middle), and an important milestone in our strategic collaboration with Sensorion. The SENS-501 program, which goals to right the deficiency of a gene chargeable for congenital deafness as a way to restore listening to, relies on very strong pioneering analysis elucidating the function of otoferlin and the pathogenic processes elicited by otoferlin defect. Its success will pave the way in which for different potential therapeutic improvements, based mostly on gene remedy in lots of types of deafness and for 1000’s of sufferers.”

Otoferlin is a protein expressed within the inside hair cells (IHC) current within the cochlea and is vital for listening to by making certain the transmission of the acoustic alerts to the auditory nerves. Otoferlin associated listening to loss is chargeable for as much as 8% of all instances of congenital listening to loss, affecting round 20,000 individuals per yr within the US and Europe. SENS-501 beforehand obtained Orphan Drug Designation from the US Meals and Drug Administration (FDA) and the European Medicines Company (EMA) and Uncommon Pediatric Illness Designation from the FDA in This fall 2022.

Pre-Scientific Information

Sensorion offered preclinical knowledge that indicated the potential for secure and environment friendly medical translation of gene remedy for otoferlin delivered by a twin AAV vector. SENS-501 administration in a DFNB9 mouse mannequin (OTOF-KO) confirmed long-term de novoexpression of otoferlin in inside hair cells (IHCs) and ABR (auditory brainstem response) restoration. Sensorion has additionally developed, in Non-Human Primates (NHPs), an optimum surgical process, just like cochlear implantation, and an administration machine system, in partnership with EVEON, which demonstrated an efficient transduction price of the focused IHCs in NHPs. EVEON designs and manufactures customized medical gadgets for the preparation and supply of medication.

“The launch of the Audiogene medical trial is a serious step ahead for deaf kids with otoferlin defects and their mother and father but additionally brings hope to individuals with genetic deafness. We’re very proud that our long-time help to French innovation, supported by Sensorion, and to the groups of Prof. Petit at Institut de l’Audition, middle of the Institut Pasteur, and Prof. Loundon, on the Scientific Heart for Analysis in Pediatric Audiology at AP-HP Necker hospital, interprets now right into a trial.”

This gene remedy for sufferers affected by otoferlin deficiency has been developed within the framework of RHU AUDINNOVE, a consortium composed of Sensorion with the Necker Enfants Malades Hospital, the Institut Pasteur, and the Fondation pour l’Audition. The undertaking is partially financed by the French Nationwide Analysis Company, by means of the “investing for the longer term” program (ref: ANR-18-RHUS-0007).
