CAMBRIDGE, Mass. and SOUTH SAN FRANCISCO, Calif., May 22, 2024 (GLOBE NEWSWIRE) -- Biogen Inc. (Nasdaq: BIIB) and Human Immunology Biosciences (HI-Bio™), a privately-held clinical-stage biotechnology company focused on targeted therapies for patients with severe immune-mediated diseases (IMDs), today announced the companies have entered into a definitive agreement under which Biogen has agreed to acquire HI-Bio for $1.15 billion upfront and up to $650 million in potential milestone payments.
HI-Bio’s lead asset, felzartamab, is a fully human anti-CD38 monoclonal antibody that has been shown in clinical studies to selectively deplete CD38+ cells including plasma cells and natural killer, or NK, cells which may allow for additional applications that improve clinical outcomes in a broad range of immune-mediated diseases.
Felzartamab has received Breakthrough Therapy Designation (BTD) and Orphan Drug Designation (ODD) from the U.S. Food and Drug Administration (FDA) for development in the treatment of primary membranous nephropathy (PMN) and has received ODD in the treatment of antibody-mediated rejection (AMR) in kidney transplant recipients. Phase 2 studies have been completed in PMN and AMR and remain ongoing in IgA nephropathy (IgAN), and HI-Bio has plans to advance each indication to Phase 3. HI-Bio plans to present two abstracts at the upcoming European Renal Association (ERA) Congress in Stockholm, including the complete Phase 2 data from the AMR study in kidney transplant patients and interim data from the Phase 2 IgAN study. Felzartamab has clinical data in AMR, PMN and IgAN indications.
“We believe this late-stage asset, which has demonstrated impact on key biomarkers and clinical endpoints in three renal diseases with serious unmet needs, is a strategic addition to the Biogen portfolio as we continue to augment our pipeline and build on our expertise in immunology,” said Priya Singhal, M.D., M.P.H., Head of Development at Biogen. “We look forward to welcoming HI-Bio employees into Biogen and, together, working to advance potential therapies for patients with rare immune diseases with high unmet need.”
“With its deep development and commercialization capabilities, Biogen is in a position to accelerate the development of new medicines, including felzartamab, for patients with severe immune-mediated diseases,” said Travis Murdoch, M.D., Chief Executive Officer of HI-Bio. “We are excited to combine the HI-Bio team’s expertise with Biogen’s global footprint.”
Biogen plans to leverage its existing global development and commercialization capabilities in rare disease and its strong scientific expertise in immunology to support the advancement of felzartamab and the HI-Bio pipeline. Biogen seeks to retain expertise and talent from HI-Bio and establish a San Francisco Bay Area team focused on expanding our efforts in immune-mediated diseases.
In addition to lead program felzartamab, the HI-Bio pipeline includes izastobart/HIB210, an anti-C5aR1 antibody currently in a Phase 1 trial and with potential for continued development in a range of complement-mediated diseases. HI-Bio also has discovery stage mast cell programs with potential in a range of immune-mediated diseases.
Financial Details and Terms of the Transaction
Under the terms of the agreement, Biogen will make an upfront payment to HI-Bio of $1.15 billion. HI-Bio’s stockholders would also be eligible for payments of up to an additional $650 million, for a total potential deal value of up to $1.8 billion, should the felzartamab programs achieve certain development milestones. The acquisition of HI-Bio is not expected to impact Biogen’s previously issued 2024 guidance. Biogen expects to finance the acquisition with cash and may also draw on its revolving credit agreement. The transaction is subject to customary closing conditions, including receipt of necessary regulatory approvals and is currently anticipated to close in the third quarter of 2024.
Advisors
Covington & Burling LLP acted as legal advisor to Biogen. Goldman Sachs & Co. LLC and BofA Securities, Inc. acted as financial advisors to HI-Bio and Goodwin Procter LLP acted as its legal advisor.
About Felzartamab
Felzartamab is an investigational therapeutic human monoclonal antibody directed against CD38, a protein expressed on mature plasma cells. Felzartamab has been shown in clinical studies to selectively deplete CD38+ plasma cells, which may allow applications that ultimately improve clinical outcomes in a broad range of diseases driven by pathogenic antibodies. Felzartamab was originally developed by MorphoSys AG for multiple myeloma. HI-Bio exclusively licensed the rights to develop and commercialize felzartamab across all indications in all countries and territories excluding China (including Macau and Hong Kong and Taiwan).
Felzartamab is an investigational therapeutic candidate that has not yet been approved by any regulatory authority.
About Antibody-Mediated Rejection (AMR) in Kidney Transplant Recipients
Antibody-mediated rejection (AMR) is a major cause of kidney transplant failure, with chronic AMR affecting ~12% of patients that receive kidney transplants annually in the U.S.1 AMR has emerged as the leading cause of late graft loss in kidney transplant recipients. Effective treatment options for chronic AMR are currently limited.2
About Primary Membranous Nephropathy (PMN)
Primary membranous nephropathy (PMN) is a rare IMD affecting the kidneys, with an estimated incidence rate of ~1/100K per year in the United States.3 There are currently no therapies specifically approved for PMN. Standard of care comprises off-label use of a variety of agents, including immunosuppressive therapies like cyclophosphamide, and CD20-targeted B-cell depleting agents such as rituximab.4 Even with these strategies, approximately one third of patients do not achieve remission.4
About IgA Nephropathy
Immunoglobulin A nephropathy (IgAN) is the most common primary glomerulonephritis worldwide. It is a leading cause of chronic kidney disease with up to 40% of IgAN patients progressing to end stage kidney disease about 20 years after diagnosis. IgAN accounts for about 40% of all native-kidney biopsies in Japan, 25% in Europe, 12% in the United States, but less than 5% in central Africa.5
