Mr. YOON said, “The seriousness of the AMR problem continues to be seriously alarmed and at the same time the need for SAL200 as a strong candidate for innovative new drugs to address it will be even greater. We will do our best to find a new out-licensing partner of SAL200, targeting global pharmaceutical companies that are trying to solve the AMR problem as well as Big Pharma.”
