Synergistic Effects Seen with Four Approved Treatment Options Including Rituximab and Ofatumumab

MorphoSys AG (FSE: MOR; Prime Standard Segment, TecDAX) today announced promising pre-clinical data on its proprietary drug candidate MOR208. MOR208 (formerly XmAb(®)5574) is a potent anti-CD19 antibody with a proprietary modification to the Fc portion that is being developed to treat B-cell malignancies. The pre-clinical data, which will be presented at the Annual Meeting of the American Society of Clinical Oncology (ASCO) on June 4, 2012, demonstrate the potential for four different combination therapies with MOR208 in models of lymphoma.

"Combination therapies including antibodies represent a promising approach to more efficacious anti-tumor therapy," commented Dr. Arndt Schottelius, Chief Development Officer of MorphoSys AG. "These intriguing results provide a first rationale for MOR208 drug combinations which warrant further evaluation in clinical trials."

MOR208 is an Fc-engineered, humanized, anti-CD19 antibody with superior cytotoxicity in a number of in vitro and in vivo models of lymphoma and leukemia. The antibody is currently being evaluated in patients with relapsed/refractory chronic lymphocytic leukemia. In the preclinical studies which will be presented in full at the ASCO meeting, approved therapeutic agents including the small-molecule drugs bendamustine (Ribomustin(®)) and fludarabine (Fludara(®)) as well as the anti-CD20 antibodies rituximab (Rituxan(®)) and ofatumumab (Arzerra(®)) were evaluated for their ability to enhance the cytotoxicity of MOR208. The in vitro and in vivo activities of MOR208 in an aggressive lymphoma model were synergistically enhanced by all applied drugs, independent of their different modes of action.

In June 2010, MorphoSys AG and Xencor signed a collaboration agreement, which provided MorphoSys with an exclusive worldwide license to MOR208. The antibody has been engineered to possess significantly enhanced antibody-dependent cell-mediated cytotoxicity (ADCC), thus improving a key mechanism for tumor cell killing and offering potential for enhanced efficacy compared to traditional antibodies for the treatment of cancer. MorphoSys will be solely responsible for further clinical development after successful completion of the currently active phase 1 clinical trial. The Company plans to initiate additional clinical trials for MOR208 in non-Hodgkin's lymphoma (NHL) and acute lymphoblastic leukemia (ALL) by the end of 2012.

MO208 represents one of four proprietary clinical programs MorphoSys is currently pursuing. The Company's proprietary portfolio also comprises MOR103, a fully human HuCAL antibody directed against GM-CSF (granulocyte macrophage-colony stimulating factor), currently in development in RA and MS, as well as MOR202, a HuCAL antibody targeting CD38, which is being evaluated in multiple myeloma.
