MorphoSys AG and Human Immunology Biosciences Inc. (HIBio) announced that the companies entered into an equity participation agreement and license agreements to allow HIBio to develop and commercialize MorphoSys' felzartamab, an anti-CD38 antibody, and MOR210, an anti-C5aR1 antibody. Under the terms of the agreements, HIBio will obtain exclusive rights to develop and commercialize felzartamab and MOR210 across all indications worldwide, with the exception of Greater China for felzartamab and Greater China and South Korea for MOR210. As part of the agreements, MorphoSys will receive a 15% equity stake in HIBio, along with certain equity earn-in provisions and standard investment rights.

MorphoSys will also be represented as a member of HIBio's Board of Directors. On achievement of development, regulatory and commercial milestones, MorphoSys will be eligible to receive payments from HIBio of up to $1 billion across both programs, in addition to tiered, single- to low double-digit royalties on net sales of felzartamab and MOR210 and will be compensated for ongoing program expenses. HIBio will assume full responsibility for future development and commercialization expenses.

Upon signing, MorphoSys also receives an upfront payment of $15 million for MOR210. Felzartamab, a novel therapeutic human monoclonal antibody derived from MorphoSys' HuCAL antibody library and directed against CD38, is being evaluated as a potential treatment for two kidney diseases, anti-PLA2R antibody-positive Membranous Nephropathy (aMN), and Immunoglobulin A Nephropathy (IgAN), where limited treatment options are available. There are two Phase 2 trials in aMN fully enrolled and underway, M-PLACE and NewPLACE, and a Phase 2 trial being conducted in IgAN, IGNAZ.

First interim data from the M-PLACE study, presented in November 2021, demonstrated that felzartamab has the potential to rapidly and substantially reduce anti-PLA2R auto-antibody titers (a serological marker for aMN) in difficult to treat patients with aMN. MOR210 is a novel human antibody directed against C5aR1, the receptor of the complement factor C5a.
