As Eli Lilly and Co. launches its recently approved Ebglyss (lebrikizumab) in an atopic dermatitis market already dominated by established biologic Dupixent (dupilumab, Regeneron Pharmaceuticals Inc.), investors tuned into an Amgen Inc. investor call disclosing positive top-line phase III results for rocatinlimab, a monoclonal antibody that could potentially offer patients a new mechanism of action. While data from the Rocket Horizon study showed rocatinlimab hit all co-primary and secondary endpoints, the early findings fell below expectations in a highly competitive market.
Amgen Inc. is looking to position inebilizumab as the first therapeutic specifically for treating immunoglobulin G4-related disease (IgG4-RD), a rare, immune-mediated condition that can affect multiple organs, after yielding what Leerink Partners analyst David Risinger called “exceptional” phase III results.
The successful suitor for Horizon Therapeutics plc has been revealed as Amgen Inc., which will buy the Dublin-based company for $27.8 billion in cash in what is by far the year’s biggest acquisition. The deal brings successful biologics into Amgen’s portfolio that include Tepezza (teprotumumab), a monoclonal antibody targeting insulin-like growth factor 1 for treating thyroid eye disease, Krystexxa (pegloticase), a pegylated uricase enzyme for treating chronic refractory gout, and Uplizna (inebilizumab), a monoclonal antibody targeting insulin-like growth factor 1 for treating thyroid eye disease.
Hansoh Pharmaceutical Group Co. Ltd. has won a green light for inebilizumab, approved by China’s NMPA for the treatment of adults with neuromyelitis optica spectrum disorders (NMOSD) who are anti-aquaporin-4 immunoglobulin G (AQP4-IgG) seropositive. The decision marked Hansoh’s first biologic approval.
Seeking to accelerate the company's long-term growth through an expansion of its rare disease pipeline, Horizon Therapeutics plc said Feb. 1 it will buy Viela Bio Inc. for $3.05 billion, or $53 per share (NASDAQ:VIE). Once closed, the deal would add a new commercial-stage asset, Uplizna (inebilizumab), to Horizon's portfolio alongside its current lead products, Tepezza (teprotumumab) for the treatment of thyroid eye disease and Krystexxa (pegloticase) for uncontrolled gout. Dublin-based Horizon, which had $2.08 billion in cash at the end of 2020, borrowed $1.3 billion to help finance the transaction. Astrazeneca plc also enabled the deal by agreeing to divest its 26.7% share in Viela Bio for a profit of between $760 million and $780 million.
The FDA’s go-ahead for Roche Holding AG’s Enspryng (satralizumab-mwge) in anti-aquaporin-4 antibody-positive neuromyelitis optica spectrum disorder had watchers of the space weighing its market odds against two therapies approved earlier: Soliris (eculizumab) from Boston-based Alexion Pharmaceuticals Inc., and the more recently cleared Uplizna (inebilizumab-cdon) from Viela Bio Inc., of Gaithersburg, Md.
