MorphoSys AG (FSE: MOR; Prime Standard Segment, TecDAX) announced today that the Company's late-breaking abstract to present data from the phase 1b/2a clinical trial evaluating its proprietary HuCAL antibody MOR103 in rheumatoid arthritis at this year's American College for Rheumatology Annual Meeting has been accepted. In addition to the safety and efficacy data published on September 20th, MorphoSys today published supplementary data from the phase 1b/2a trial including EULAR response rates, changes in DAS28 scores as well as RAMRIS scores used to analyze MRI imaging in RA trials.

In the randomized, double-blind, placebo-controlled phase 1b/2a trial in 96 mild to moderate RA patients, MOR103 was administered in four weekly doses of 0.3 mg/kg, 1.0 mg/kg or 1.5 mg/kg. MOR103 showed excellent safety data at all doses administered. With regards to efficacy, the trial was designed to look in particular at the onset of the therapeutic effect. At week four, a significant decrease of the DAS28 score was seen in the MOR103 group with a mean difference of 1.12 and 0.61 in the 1.0 mg/kg and 1.5 mg/kg cohorts respectively, while an increase of 0.17 was documented for placebo. EULAR response criteria were met in 68.2% of the 1.0 mg/kg dose group and in 69.5% of the 1.5 mg/kg dose group in comparison to 7.4% in the placebo group. The clinical activity was mirrored by a reduction in the RAMRIS score for joint swelling/synovitis of up to -1.5 within 4 weeks.

"We are very excited about the opportunity to present the data at this year's American College for Rheumatology meeting, the most relevant medical conference for RA. This is a major milestone for us," commented Dr. Arndt Schottelius, Chief Development Officer of MorphoSys AG. "The additional clinical data we have published today further underline the compound's potential to become an important new drug in an area of unmet medical need."

The data will be presented by the principal investigator of the study, Prof. Harald Burkhardt, Professor of Rheumatology and Head of the Division of Rheumatology at Goethe University Frankfurt in a presentation session on November 13, 2012.
