Cilcare is a biotechnology company headquartered in Montpellier, France. Since its establishment in 2014, the company has been leveraging auditory science to provide drug development support services for hearing-related disorders such as hearing loss and tinnitus, while also developing proprietary therapeutic candidates and providing AI-powered auditory data analytics.

The company provides pharmaceutical and biotechnology companies with services including efficacy evaluation, clinical trial implementation, regulatory support, and market analysis. By utilizing digital technologies to deliver rapid data analysis, Cilcare helps improve the efficiency of research and development processes. The company is also advancing the development of hearing loss therapeutic candidates, including CIL001 and CIL003.

Having built collaborative relationships with Japanese companies for nearly a decade, Cilcare established its Japanese subsidiary, Cilcare K.K., in Chuo-ku, Tokyo, in April 2026. Through its presence in Japan, the company aims to strengthen the planning and promotion of joint research and clinical trials with domestic companies and research institutions, while enhancing technical support and business development activities to further expand its operations in the Japanese market.

Cilcare’s R&D in auditory science

The JETRO Invest Japan Business Support Center (IBSC) supported the company's entry into Japan by providing intensive consultation services on company registration, visa procedures, labor matters, and taxation throughout the incorporation process.

Cilcare's entry into Japan is expected to facilitate the use of its expertise in hearing disorders and AI-based auditory data analytics technologies in a market where addressing hearing loss is becoming increasingly important due to population aging. The company's presence is also expected to support the Japanese government's efforts to strengthen drug discovery capabilities and promote innovation in the healthcare and medical sectors.
