MONTPELLIER, France, September 27, 2021--(BUSINESS WIRE)--Regulatory News:

Sensorion (Paris:ALSEN) (FR0012596468 – ALSEN), a pioneering clinical-stage and gene therapy biotech company specializing in the development of novel therapies to restore, treat, and prevent within the field of hearing disorders, today announces its interim annual results as of June 30, 2021 alongside its outlook for the remainder of 2021.

"Many elements of Sensorion’s strategic planning came together in a successful first half of 2021. Our otoprotectant small molecule SENS-401 continued to make clinical and regulatory progress. Regulators accepted our proposal to reduce the sample size of our study in Sudden Sensorineural Hearing Loss; we will open a new combined study on SENS-401 in cisplatin-induced ototoxicity in H2 2021; and our partnership with Cochlear Limited will take SENS-401 into the clinic in combination with cochlear implantation. Sensorion’s gene therapy programs, made progress too. Recently we received feedback from regulatory advisors of the EMA that was aligned with the assumptions of our otoferlin gene therapy development program. At the start of 2021, we had announced our third and potentially largest gene therapy collaboration with our long-term partners at the Institut Pasteur, on GJB2. This program creates significant opportunities in both adult and pediatric hearing loss. In addition, part of the deal we announced with Sonova will involve genotyping to survey gene variants associated with progressive hearing loss in adults, including GJB2. This might represent a first step in bringing together routine diagnosis of hearing loss with advanced treatments such as gene therapy" said Nawal Ouzren, CEO of Sensorion.

Key developments in H1 2021: science and operational

Gene Therapy programs

  • Third collaboration with Institut Pasteur: GJB2 gene therapy targeting adult and pediatric segments

On February 15, 2021, Sensorion announced its largest gene therapy opportunity to date, a collaboration with Institut Pasteur, targeting the GJB2 gene in pediatric and adult deafness. Research by the Institut Pasteur demonstrated anomalies in GJB2 are both the most common cause of congenital deafness as well as a wide contributor in adult cases of severe age-related hearing loss. Although the types of GJB2 mutation in children and adults may differ, gene therapy could potentially provide solutions in both spheres.

Sensorion's GJB2 gene therapy programs have the potential to address three pathologies related to GJB2 mutations: age-related hearing loss in adults, progressive forms of hearing loss in children, and pediatric congenital deafness. Initially, the focus will be on the first two populations and in particular the adult population with GJB2-associated hearing loss where the unmet medical need is well-defined, becoming the first company to address this important and potentially large market segment. Sensorion will later target the pediatric need related to GJB2.

  • OTOF-GT gene therapy program: clear advice from the European Medicines Agency to progress the program

Sensorion sought scientific advice from EMA on the preclinical and clinical development plans for OTOF-GT, the Company’s dual vector AAV gene therapy program for the treatment of children born with hearing loss caused by otoferlin deficiency.

In Q3 2021, Sensorion received clear feedback from the EMA’s advisors on the overall development plan for OTOF-GT, which was consistent with the Company’s preclinical and clinical development plans. The agency’s advisors also welcomed the ongoing Natural History Study, Audioferline (NCT04202185), a component of the AUDINNOVE project coordinated by researchers at Hôpital Necker-Enfants malades (Necker Hospital) in partnership with Sensorion. Sensorion’s aim is to document the natural course of disease progression in otoferlin deficiency patients, define clinically meaningful endpoints suitable for market approval, and identify the patient populations that would benefit the most from Sensorion’s OTOF-GT treatment.

The Natural History Study will enable Sensorion to select the most relevant and clinically meaningful endpoints and clinical trial design as OTOF-GT progresses into the clinic.

Sensorion expects to file a Clinical Trial Application (CTA) for its OTOF-GT program in H1 2023.

  • Usher-T1-GT project

We have completed the preclinical proof-of-concept study for our gene therapy approach in Usher’s syndrome (USHER-GT). The study was designed to test whether a gene therapy approach would be effective in older mice, thereby opening the possibility of extended treatment window for clinical studies.

The results of the completed study require further analysis with some indications of hearing restoration in the older animals and complete restoration of the vestibular function. The company will continue to review the results before providing a more detailed update on the implications of the study in the coming months.

Drug candidate SENS-401

Our clinical program with otoprotective small molecule SENS-401 continued to progress in 2021 in different indications: Sudden Sensorineural Hearing Loss (SSNHL), Cisplatin-Induced Ototoxicity (CIO) and cochlear implantation.

  • SENS-401 in SSNHL: AUDIBLE-S Phase 2 protocol amendment approved

In March 2021, Sensorion announced plans to approach regulators to reduce the study sample size following a review of the trial design and statistical analysis plan for the AUDIBLE-S study in patients with Sudden Sensorineural Hearing Loss (SSNHL).

In September 2021, Sensorion announced that these amendments to AUDIBLE-S were approved by 9 out of 10 regulatory authorities of all participating countries, the last one still being under evaluation. The recruitment target had been significantly reduced without compromising the quality or potential outcome of the trial. The study has now a recruitment target of 111 patients and has enrolled 112 patients. Since not all of the patients have yet completed their 28-day end of treatment visit, Sensorion will continue the recruitment until the end of October 2021. Top line data continues to be expected around year end (see post-closing events).

  • SENS-401 in CIO: clinical trial application filing confirmed in H2 2021

Following SENS-401’s demonstrated ability to significantly reduce hearing loss in a rat model of cisplatin-induced ototoxicity (CIO, Petremann et al., 2017), Sensorion will initiate a Phase 2 clinical study of SENS-401 in adults with CIO in H2 2021, as previously announced.

The trial will have three arms, including a control arm without SENS-401. The natural history study (NHS) of CIO the company had planned to begin at the end of H1 2021 is now included as the control arm. Sensorion’s modified strategy condenses the clinical timelines of the CIO program, provides a more robust and relevant control arm for the study and makes SENS-401 available sooner to patients being treated with cisplatin therapies.

  • SENS-401 for hearing preservation in combination with cochlear implantation: to begin first clinical trial with Cochlear Limited

On January 19, 2021, Sensorion released positive preclinical data demonstrating that the combination of its SENS-401 molecule and a cochlear implantation helped reduce loss of residual hearing at a frequency located beyond the electrode array. Preservation of ‘natural’ hearing is particularly important in speech recognition.

Following this initial success, Sensorion and Cochlear announced the initiation of a Phase 1 clinical trial of SENS-401 (Arazasetron) in patients scheduled for cochlear implantation on September 8, 2021. The study will be sponsored by Sensorion and the proposed design is expected to be submitted to regulatory authorities during H2 2021 (see post-closing events).

Multi-year strategic collaboration with Sonova

On September 15, 2021, Sensorion announced the signing of an important multi-year collaboration with Sonova, a leading international player in the hearing solutions market. The collaboration aims to create new diagnostic and therapeutic solutions for hearing loss and it brings to fruition the exclusive negotiations commitment made between the two companies in December 2020, when Sonova acquired a 3.7% stake in Sensorion.

Part of the deal is a jointly-funded study of natural history in age-related progressive hearing loss (presbycusis) in adults. It will involve the collection of disease information and samples via selected Sonova Audiological Care stores. This will be followed by genotyping to better understand the prevalence of gene variants thought to be associated with progressive hearing loss in adults, including GJB2. The collaboration could lead to the introduction of genetic analysis to the routine diagnosis of progressive hearing loss in adults and subsequently open the way for improved care through a combination of advanced therapeutic interventions and traditional hearing solutions including hearing aids. Sonova and Sensorion will jointly fund the study with €7.0 million, split 70/30 between the two companies (see below post-closing events).

Strengthened scientific and medical leadership

As Sensorion expands and builds its product development capabilities, it has expanded its senior management team with the creation of two new senior executive positions.

In June, gene therapy and rare disease expert, Dr Nora Yang, was named as the company's new Chief Scientific Officer based in the USA. Dr Yang leads the preclinical organization and spearheads the development of collaborations between fundamental and clinical research, including working with Sensorion's partner, Institut Pasteur.

In July, Dr Otmane Boussif was appointed to the newly created position of Chief Technology Officer. Dr Boussif, formerly headed Gene Therapy CMC at Novartis, and oversees now all of Sensorion's technical operations and CMC functions.

Both positions will be critical in taking Sensorion's pipeline forward and securing regulatory approvals.

Scientific communications

Sensorion presented at various scientific congresses and hosted one Key Opinion Leader (KOL) event in H1 2021 including:

  • Christine Le Bec, Head of CMC Gene Therapy, spoke in the "Gene Therapy Analytics and Manufacturing" session at the 4th Annual Bioprocessing Summit Europe, in March 2021. Dr Le Bec’s talk on "Quality Control for a Dual AAV Vector" focused on product characterization and quality control aspects of Sensorion’s gene therapy program in Otoferlin deficiency, where the size of the Otoferlin gene requires the use of a dual AAV vector system.

  • Sensorion hosted a Key Opinion Leader (KOL) Webinar with Dr. Thomas Lenarz on the GJB2 Gene Related Hearing Loss on May 10, 2021. Dr Lenarz discussed the clinical aspects, current treatment landscape and unmet medical need in treating patients with pediatric onset of GJB2–related hearing loss as well as the role of the GJB2 gene.

  • Christine le Bec co-chaired a scientific session on the "Development of AAV Capsid Variants" at the American Society of Gene & Cell Therapy (ASGCT) Annual meeting, that took place virtually on 11-14 May 2021.
    In addition, Sensorion's Research Team presented an overview of the company's Gene Therapy platform focused on hearing disorders at the ASGCT Annual Meeting, held in May 2021.

Others

During the first half of 2021, Sensorion Inc subsidiary was created in the United States.

H2 2021 announcements

Since the end of June 2021, the key business updates are as follows:

  • The company incorporated a wholly owned subsidiary in Australia, Sensorion Australia, in July 2021.

  • On September 8, 2021, Sensorion and Cochlear reported the initiation of the first clinical trial of SENS-401 for hearing preservation in combination with cochlear implantation. The study aims to measure the perilymph PK of SENS-401 and to explore the therapeutic effect of SENS-401 on early hearing outcomes upon cochlear implantation. The trial will be fully funded under the existing agreement between Cochlear and Sensorion. The study will be sponsored by Sensorion and the proposed design is expected to be submitted to the regulatory authorities in H2 2021.

  • On September 15, 2021, Sensorion and hearing care leader Sonova signed a strategic research collaboration which covers a jointly funded Natural History Study in age-related hearing loss (presbycusis). It is intended that large-scale genetic screening and clinical follow-up will be performed in collaboration with Sonova Audiological Care stores. The key element of the collaboration between Sensorion and Sonova is a natural history study including genotyping thousands of patients suffering from early onset of severe presbycusis with the aim of confirming approximately a hundred patients for specific variants of gene mutations.

  • On September 24, 2021, Sensorion announced that 9 out of 10 regulatory authorities of all participating countries have approved Sensorion’s amendment to the Phase 2 AUDIBLE-S study protocol with SENS-401 in Sudden Sensorineural Hearing Loss (SSNHL). Sensorion had submitted to the regulatory authorities an amendment to the statistical analysis plan for the AUDIBLE-S study that significantly reduced the recruitment target to 111 patients without compromising the quality or potential outcome of the trial. The study has now enrolled 112 patients. Since not all patients have yet completed their 28-day end of treatment visit, Sensorion will continue the recruitment until the end of October 2021. Top line data continue to be expected around year end.
