SOCIUM Inc. started its operations in September 2017 with a corporate mission,“Drug discovery for patients with no drug, Drug discovery for patients with ineffective drug.”

“socium” means “Partner” in Latin. SOCIUM committed to being a partner with people that hope to enjoy healthier life.

We have a precise understanding of the challenges associated with drug discovery and provide optimal solutions based on our proven proprietary technologies.

Simultaneously, we utilize these proprietary technologies to identify existing drugs that demonstrate efficacy for diseases lacking treatment options, particularly rare diseases. Our aim is to swiftly bring these treatments to patients through borderless co-development initiatives.
