The approval of HYQVIA by the European Commission is a significant milestone for Takeda, likely to have a positive impact on the company's stock in the short term. It strengthens Takeda's position in the market for neuroimmunological treatments and could lead to increased sales and market share in this segment. The uniqueness of the treatment as a once-monthly, at-home or in-office option could make it a preferred choice for patients and healthcare providers, potentially leading to higher demand.
