Option Agreement with Cilcare for Development Compounds Addressing Hearing Loss

OSAKA, Japan, June 6, 2024 - Shionogi & Co., Ltd. (Head Office: Osaka, Japan; Chief Executive Officer: Isao Teshirogi, Ph.D.; hereafter "Shionogi") announced that Shionogi has entered into an option agreement with Cilcare DEV SAS (Head Office: Montpellier, France; Chief Executive Officer: Celia BELLINE, hereafter “Cilcare”) to acquire the exclusive license for the development, manufacturing, and commercialization of CIL001 and/or CIL003, the hearing loss treatment drug candidates worldwide. In conjunction with the signing of the agreement, Shionogi will make an upfront payment of Euros 15 million to Cilcare. If Shionogi exercises its option for both compounds and development and commercialization proceeds successfully, the total of the option payments and development, regulatory, and sales milestones may reach approximately Euros 400 million, plus royalties on net sales.

 

Cilcare has been developing CIL001, a novel candidate drug for hearing loss treatment with auditory nerve protective effects. Currently, preparatory activities are underway to collect auditory data in patients with type 2 diabetes or mild cognitive impairment. From the fiscal year 2025, Phase 2a studies are planned to evaluate the safety and efficacy of CIL001 in patients with type 2 diabetes who have cochlear synaptopathy. Additionally, preclinical studies for CIL003 are currently underway. Shionogi will decide whether to exercise the option right based on the results of the Phase 2a studies of CIL001 and preclinical study data of CIL003, both to be conducted by Cilcare.

 

Hearing loss is a major global health issue affecting around 1.5 billion people worldwide. Its incidence is rapidly increasing, with predictions that, by 2050, a quarter of the global population will experience varying degrees of hearing deficiency1. Hearing loss, particularly when it primarily affects the cochlear synapses*1 in the inner ear, is known as cochlear synaptopathy. This condition is also known to increase the risk of dementia in the elderly and is also an important complication of diabetes2. However, there are no effective treatments available, making it a condition with a high unmet need. The economic loss due to unaddressed hearing loss is said to be around 1 trillion dollars annually, and there is a demand for new therapeutic drugs3.

 

Shionogi has identified Contributing to a Healthy and Prosperous Life as a material focus. We are committed to creating a society where everyone can lead a longer, more vibrant life, realizing their goals. Shionogi continues to strive to deliver innovative treatments for diseases with high unmet medical needs, including hearing loss, to patients as quickly as possible.

About CIL001

CIL001 is a novel candidate drug for hearing loss treatment with auditory nerve protective effect, licensed by Sanofi to Cilcare in 2020. In preclinical studies to date, CIL001 has been confirmed to have an organic effect that repairs inner ear cochlear synapses, and a functional effect that improves the first wave of the auditory brainstem response (ABR)*2.

 

About Hearing loss

Hearing loss is a major global health issue affecting around 1.5 billion people worldwide. The significant surge in its incidence is attributed to the growing global population and an increase in the elderly demographic. If this trend continues, it will result in higher health insurance costs, social isolation, poverty, and a decrease in productivity, leading to substantial losses for society. One of the challenges with hearing loss is its gradual onset, making it difficult for patients to recognize and leading to low diagnosis rates. It is known to hinder various social activities, including communication with others, and is also considered a risk factor for central nervous system diseases.

 

*1 Cochlear synapse: The site of information transmission in the cochlea of the inner ear, connecting sensory

cells (hair cells) and nerve cells.

*2 Auditory brainstem response (ABR) Wave I: The first electrical signal generated by cochlear nerve cells in

response to an auditory stimulus, believed to reflect the function of the cochlear synapse.
