MorphoSys Reports Successful Phase 1 Study of MOR103 Using a Subcutaneous Administration

November 12, 2012 / 7:30 am, CET

Results Underline the Compound's Potential to be an Important New Drug for the Treatment of Chronic Inflammatory Diseases
 
MorphoSys AG (FSE: MOR; Prime Standard Segment, TecDAX) today announced that subcutaneous administration of its HuCAL-based monoclonal antibody MOR103 was safe and well tolerated and demonstrated a favorable and competitive pharmacokinetic profile in a clinical Phase I study in healthy volunteers. This competitive pharmacokinetic profile is demonstrated by a half-life of 17 days and good bioavailability supporting subcutaneous administration of MOR103 in future clinical trials. Furthermore, the high neutralizing potency was shown to be comparable to the intravenous administration.

Subcutaneous injection represents a more convenient route of administration for patients and the data will help guide dosing regimens for future clinical trials with MOR103. The phase 1 pharmacokinetic study was conducted in 32 healthy volunteers and sequentially assessed single doses of 0.5, 1.0 and 2 mg/kg MOR103 administered subcutaneously compared to 2 mg/kg MOR103 after single intravenous dosing in cohorts of 8 volunteers.

"We are very pleased with these data showing that a subcutaneous administration of our MOR103 antibody is a feasible and attractive option for the future treatment of various inflammatory diseases with this compound," commented Dr. Arndt Schottelius, Chief Development Officer of MorphoSys AG. "In addition to the excellent safety and efficacy data we have presented seven weeks ago, today's news adds another valuable component to the broad commercial and scientific package we are building around our anti GM-CSF program."

MOR103 has concluded a phase 1b/2a clinical trial evaluating the compound in rheumatoid arthritis. The efficacy and safety data observed underline MOR103's potential to become a first-in-class treatment modality for RA patients, with a novel and differentiated mechanism of action. Additionally, MOR103 is currently being evaluated in a phase 1b dose-escalation study in multiple sclerosis.
