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.”
Wall Street got what it wanted from Vera Therapeutics Inc. with atacicept in IgA nephropathy (IgAN) and rewarded shares of the Brisbane, Calif.-based firm (NASDAQ:VERA), pushing them to close Jan. 25 at $25.31, up $8.29, or 49%.
The paper published June 19 in Nature Genetics that described a genome-wide analysis to narrow down the implicated pathogenic signaling pathways and “prioritize drug targets for IgA nephropathy [IgAN]” no doubt proved of great interest to developers, plenty of which are busy in the space.
Alpine Immune Science Inc.’s update in its earnings report Nov. 14 on its ALPN-303 program added more intrigue to the notion of targeting B cell cytokines B cell activating factor (BAFF) and a proliferation-inducing ligand (APRIL) together in lupus, as other players are trying the dual approach as well, including China’s Remegen Co. Ltd. and Vera Therapeutics Inc.<
A second death in the study of davoceticept (ALPN-202) has prompted Alpine Immune Sciences Inc. to stop enrolling participants in two phase I studies of the CD28 co-stimulator and dual checkpoint inhibitor, throwing the program’s future into doubt.
A patient’s death has caused the FDA to place a partial clinical hold on Alpine Immune Sciences Inc.’s phase I study NEON-2 in adults with advanced malignancies.
The worldwide option and license agreement Alpine Immune Sciences Inc. drew up with Abbvie Inc. for ALPN-101, a dual CD28/ICOS co-stimulation antagonist for treating systemic lupus erythematosus and other autoimmune diseases, heartily strengthened Alpine’s stock and supports its planned operations into 2023.
