SK Bioscience Co. Ltd. won €50 million (₩75.5 billion, US$52.03 million) up front from Sanofi SA to expand an earlier agreement to develop and commercialize novel pneumococcal conjugate vaccines (PCVs). The first deal resulted in GBP-410 (SP-0202), its pediatric 21-valent PCV candidate that moved into phase III study last week.
