Vertex Pharmaceuticals Inc. is acquiring Alpine Immune Sciences Inc. for $4.9 billion in cash to gain Alpine’s lead product, phase III-ready povetacicept, which demonstrates best-in-class potential in patients with immunoglobulin A nephropathy (IgAN). Povetacicept (ALPN-303), or “pove,” holds potential “as a pipeline in a product in a number of other serious renal diseases and cytopenias,” Vertex CEO Reshma Kewalramani said during an April 10 conference call, noting that the deal was “just the right fit with just the right assets at just the right phase of development where Vertex can add value.”
