Financial Analyst Perspective
From a financial standpoint, the launch of LEQEMBI in South Korea represents a significant milestone for Biogen and Eisai, potentially opening up a lucrative market given the high prevalence of dementia in the region. The collaboration between the two companies has been fruitful, with LEQEMBI already approved in several major markets. However, investors should be mindful of the potential risks associated with adverse events and the ongoing regulatory reviews in other regions, which could impact future revenue streams.
