Singapore has become a biopharma manufacturing hub, drawing the likes of Novartis ($NVS), GlaxoSmithKline ($GSK) and Amgen ($AMGN). Even Russia's Pharmstandard has an API facility there. Now AbbVie ($ABBV) will join the group. The maker of Humira, the best-selling drug in the world, said Wednesday that it will invest $320 million to build its first facility in Asia. The plant will be designed for both small-molecule production and biologic active ingredients for AbbVie's oncology and immunology pipeline. Story
