MorphoSys AG (FSE: MOR; Prime Standard Segment, TecDAX) announced the completion of a first dosing regimen in a phase 1 clinical study on healthy volunteers of the HuCAL-derived antibody MOR103 with no adverse events reported. Six healthy volunteers in the first dosing group have been enrolled and received MOR103 injections, three volunteers received placebo. The safety review of the medical data from the lowest dosing group concluded that it was safe to proceed to the second dosing group. The randomized, double-blind, placebo-controlled, single-ascending dose trial will be conducted in approx. 50 healthy volunteers and is being conducted in a Clinical Pharmacology Unit (CPU) in Utrecht, the Netherlands. The trial is scheduled to be finalized in 2008 and final reporting is expected in Q1 2009.

The company's lead development program MOR103 is a fully human HuCAL antibody directed against GM-CSF (granulocyte macrophage-colony stimulating factor), being developed in the area of inflammatory diseases, such as rheumatoid arthritis, where current treatment options are inadequate. Due to its diverse functions in the immune system, GM-CSF can be considered a target for a broad spectrum of anti-inflammatory therapies. MorphoSys had submitted the clinical trial application in December 2007 and received the approval by the Dutch authorities six weeks later. The study will evaluate the safety and tolerability as well as pharmacokinetics of escalating doses of MOR103.

"We are very pleased to see our first proprietary drug candidate progress according to plan," commented Dr. Marlies Sproll, Chief Scientific Officer of MorphoSys AG. "Antibodies that neutralize GM-CSF could represent a new generation of medicines that reduce inflammation with greater beneficial effects."

About MOR103 to treat RA

Rheumatoid arthritis (RA) is traditionally considered a chronic, inflammatory autoimmune disorder that causes the immune system to attack the joints and affects in particular a membrane, called synovium, which lines each movable joint. It is a disabling and painful inflammatory condition, which can lead to substantial loss of mobility due to pain and joint destruction. As a systemic disease, RA often affects extra-articular tissues throughout the body including the skin, blood vessels, heart, lungs, and muscles. The disease affects approximately 4-6 million people worldwide. In patients suffering from RA, white blood cells move from the bloodstream into the synovium. Here, these blood cells appear to play an important role in causing the synovial membrane to become inflamed.

The HuCAL-based antibody MOR103 targets GM-CSF as a means to treat inflammatory diseases such as psoriasis, multiple sclerosis (MS), chronic obstructive pulmonary disease (COPD), asthma, and especially RA. The granulocyte macrophage colony-stimulating factor (GM-CSF) stimulates stem cells to produce granulocytes and macrophages, and subsequently activates these differentiated immune cells. GM-CSF is part of the natural immune and inflammatory cascade but has also been identified as an inflammatory mediator in autoimmune disorders like RA leading to an increased production of pro-inflammatory cytokines, chemokines and proteases and thereby ultimately to articular destruction. By neutralizing GM-CSF the HuCAL-based antibody MOR103 reduces undesired proliferation and activation of inflammatory granulocytes and macrophages and intervenes in several pathophysiological pathways.
