MorphoSys to Hold Public Conference Call (in English) on Wednesday, 20 August 2014, at 2:00pm CEST (1:00pm BST/8:00am EDT)

MARTINSRIED, Germany and MUNICH, Germany I August 19, 2014 I MorphoSys AG (FSE: MOR; Prime Standard Segment, TecDAX, OTC: MPSYY) and Emergent BioSolutions Inc. (EBS) today announced an agreement for the joint development and commercialization of ES414. The compound, to be renamed MOR209/ES414, is an anti-PSMA/anti-CD3 bi-specific antibody targeting prostate cancer, which was developed by Emergent using its proprietary ADAPTIRTM (modular protein technology) platform. Preclinical in vitro and in vivo studies have shown that MOR209/ES414 redirects T-cell cytotoxicity towards prostate cancer cells expressing Prostate Specific Membrane Antigen (PSMA), an antigen commonly found on such cells.

Under the terms of the agreement, MorphoSys gains worldwide commercialization rights excluding the U.S. and Canada, where Emergent will retain rights. Emergent will receive an upfront payment of US$20 million and will be eligible to receive potential milestone payments of up to US$163 million. The milestone payments are linked to specific events, including successful development of MOR209/ES414 in several indications and securing approval in certain territories. MorphoSys and Emergent will jointly develop MOR209/ES414, with MorphoSys bearing 64% and Emergent 36% of the total costs. Emergent will manufacture and supply clinical material from its manufacturing facilities in Baltimore, Maryland. Emergent will receive low single digit royalties on product sales in MorphoSys’s territory and MorphoSys will receive tiered royalties from mid-single digit up to 20% on product sales in Emergent’s territory. Additional financial details were not disclosed.

Dr. Arndt Schottelius, Chief Development Officer of MorphoSys, added: “We are pleased to be working with Emergent BioSolutions. We believe MOR209/ES414 has the potential to be an important therapy for prostate cancer, where there is a pressing need for better treatments. The preclinical data suggest that the molecule has a number of potential advantages over other drug candidates in this indication. Our goal is to combine our capabilities with those of Emergent to enable the fastest possible development and commercialization of MOR209/ES414.”

Barry Labinger, Executive Vice President and President Biosciences Division at Emergent BioSolutions, stated: “Emergent looks forward to collaborating with MorphoSys to potentially address important unmet needs amongst patients suffering from prostate cancer. Our companies bring complementary capabilities, compatible cultures and values, and a shared commitment to the highest quality development and commercialization of MOR209/ES414. We expect to begin clinical development within the next six months. We are encouraged by our partnership with MorphoSys and the continued interest of multiple parties in our ADAPTIR platform.”

MorphoSys and Emergent plan to initiate a Phase 1 clinical trial evaluating MOR209/ES414 in patients with metastatic castration-resistant prostate cancer (mCRPC) within the next six months. The initial phase of the trial will be conducted in the U.S. and Australia, with Emergent as the sponsor.

MorphoSys will hold a public conference call tomorrow, 20 August 2014, at 02:00 p.m. CEST (08:00 a.m. EDT, 01:00 p.m. BST), to present key information on the agreement with Emergent BioSolutions.

About MOR209/ES414
MOR209/ES414 is a targeted immunotherapeutic protein, which activates host T cell immunity specifically against prostate cancer cells expressing Prostate Specific Membrane Antigen (PSMA), an antigen commonly overexpressed on prostate cancer cells. The MOR209/ES414 molecule was constructed using Emergent’s ADAPTIR technology platform and selectively binds to the T cell receptor on cytotoxic T cells and PSMA on tumor cells. MOR209/ES414 contains two pairs of binding domains, each targeting a unique antigen, linked to opposite ends of an immunoglobulin Fc domain to extend the half-life and enable use of a purification process typical of lg-based molecules. In preclinical studies, MOR209/ES414 has been shown to redirect T cell cytotoxicity towards prostate cancer cells expressing PSMA.

About the ADAPTIR(TM) Platform
ADAPTIR bispecific proteins are modular, single chain polypeptides that comprise two separate binding domains, a hinge segment, and an effector domain (huFc). They have a differentiated structure from monoclonal antibodies and can generate a unique signaling response. Some ADAPTIR molecules, like MOR209/ES414, may mediate T cell cytotoxicity by redirecting T cells against tumor cells. In addition, monospecific ADAPTIR proteins may mediate complement dependent cytotoxicity and Fc dependent cytotoxicity, similar to monoclonal antibodies.

About Prostate Cancer
Prostate cancer is the most common cancer in men with approximately 230,000 new cases annually in the United States or 900,000 new cases annually worldwide. Screening, radiation, surgery and hormone ablation therapy have greatly improved the detection and treatment of early stage prostate cancer. However, the new therapies only improve life expectancy by a few months for patients with metastatic castration-resistant prostate cancer.

About MorphoSys
MorphoSys developed HuCAL, the most successful antibody library technology in the pharmaceutical industry. By successfully applying this and other patented technologies, MorphoSys has become a leader in the field of therapeutic antibodies, one of the fastest-growing drug classes in human healthcare.

Together with its pharmaceutical partners, MorphoSys has built a therapeutic pipeline of more than 80 human antibody drug candidates for the treatment of cancer, rheumatoid arthritis, and Alzheimer’s disease, to name just a few.
