MUNICH, Germany I November 5, 2012 I MorphoSys AG (FSE: MOR; Prime Standard Segment, TecDAX) announced today the publication of additional preclinical data on its two proprietary cancer programs MOR208 and MOR202 in the online issue of the peer-reviewed medical journal BLOOD. The data sets further underline the potential of both compounds to result in new treatment options for various forms of blood-borne cancer. Full data will be presented at the 2012 American Society of Hematology (ASH) annual meeting on December 8-11, 2012 in Atlanta.

MOR208, an anti-CD19 antibody with a proprietary modification to the Fc portion, has successfully concluded a phase 1/2a clinical trial in chronic lymphocytic leukemia (CLL). The program is on track to enter clinical development in non-Hodgkin’s lymphoma (NHL) and acute lymphoblastic leukemia (ALL). The preclinical in vitro study to be presented at ASH examined MOR208’s potential to trigger antibody-dependent cell-mediated cytotoxicity (ADCC) relative to a native non-engineered anti-CD19 antibody. In the study, MOR208 showed significantly enhanced cytotoxicity triggering killing of cancer cells derived from both pediatric and adult patients with ALL. MOR208 was twice as effective as the non-engineered antibody and required lower antibody levels and lower presence of effector cells.

MOR202, an anti-CD38 HuCAL antibody, is currently being tested in a phase 1/2a study in patients with relapsed or refractory multiple myeloma (MM). Having previously identified ADCC as an effector mechanism of MOR202, the preclinical data to be presented at ASH demonstrate the antibody’s capability to induce killing of MM patient cells via antibody dependent cellular phagocytosis (ADCP) as an additional potent mechanism.

"These findings for our proprietary cancer programs MOR202 and MOR208 are very encouraging and highlight the significant potential of both candidates. MOR208 may represent a promising approach for treatment of pediatric and adult ALL," commented Dr. Arndt Schottelius, Chief Development Officer of MorphoSys AG. "For MOR202, the additional effector mechanism bodes well for future clinical development in multiple myeloma."

In total, MorphoSys currently has four proprietary clinical programs ongoing, namely MOR208 and MOR202, as well as MOR103, a fully human HuCAL antibody directed against GM-CSF (granulocyte macrophage-colony stimulating factor), that is being developed in rheumatoid arthritis and multiple sclerosis.
