Sosei Heptares is fulfilling its ambition for growth in the Asia-Pacific region by buying the Japanese and South Korea businesses of Swiss biotech Idorsia Ltd. for ¥65 billion (US$463 million), potentially freeing Idorsia from its struggle to prove its stroke drug, Pivlaz (clazosentan), is effective enough to warrant approval in key Western markets.
