MorphoSys Announces That Its Licensee Janssen Has Initiated Two Phase 3 Studies with TremfyaTM (Guselkumab) in Psoriatic Arthritis


MorphoSys AG (FSE: MOR; Prime Standard Segment, TecDAX; OTC: MPSYY) announced today that its licensee Janssen Research & Development, LLC (Janssen) has initiated two phase 3 clinical trials to evaluate the efficacy and safety of TremfyaTM (guselkumab) in the treatment of patients with psoriatic arthritis (PsA), a chronic, immune-mediated inflammatory disease affecting both the joints and the skin. TremfyaTM is a fully human anti-IL-23 monoclonal antibody developed by Janssen, and was generated utilizing MorphoSys's proprietary HuCAL antibody technology.

MorphoSys will receive a milestone payment from Janssen in connection with the start of phase 3 development in PsA. Financial details were not disclosed.

Dr. Markus Enzelberger, Interim Chief Scientific Officer of MorphoSys AG, said: "We are very pleased that our licensee Janssen has started pivotal phase 3 development with TremfyaTM in psoriatic arthritis. If successful, this could result in a further expansion of the therapeutic range of the compound. Through Janssen's innovative development of TremfyaTM leading to U.S. FDA approval, it recently became the first therapeutic antibody based on MorphoSys's technology platform that has been made available to patients in the U.S."

More information on the clinical studies of TremfyaTM (guselkumab) is available on

About Psoriatic Arthritis
Psoriatic arthritis (PsA) is a chronic, immune-mediated inflammatory disease characterised by both joint inflammation and the skin lesions associated with psoriasis, the latter of which affects 125 million people worldwide. An estimated 600,000 Americans-and more than 12 million people worldwide-have PsA. Up to 30 percent of people with psoriasis are estimated to also develop psoriatic arthritis. The disease causes pain, stiffness and swelling in and around the joints and commonly appears between the ages of 30 and 50, but can develop at any time. Though the exact cause of psoriatic arthritis is unknown, genes, the immune system and environmental factors are all believed to play a role in the onset of the disease.
