About Karo Bio
Karo Bio is a pharmaceutical company focused on the research and
development of innovative drugs for unmet medical needs. Karo Bio's
vision is to become a pharmaceutical company with sustainable
profitability, commercial products and a competitive project portfolio.

Karo Bio runs a number of development projects within the indication
areas cardiovascular and metabolic diseases, neuropsychiatry,
inflammatory conditions, autoimmune diseases, cancer and women's health.
An important foundation for the company's activities is its unique
