MARTINSRIED / MUNICH, Germany, Dec. 8, 2014 (GLOBE NEWSWIRE) -- MorphoSys AG (FSE: MOR; Prime Standard Segment, TecDAX; OTC: MPSYY) today announced promising clinical data on its proprietary drug candidate MOR208 from a phase 2a study in 89 patients with four different subtypes of relapsed or refractory Non-Hodgkin's Lymphoma (NHL). MOR208 is a potent anti-CD19 antibody with a proprietary modification to the Fc portion that is being developed to treat B-cell malignancies. The preliminary clinical data, which were presented today at the 56th Annual Meeting of the American Society of Hematology (ASH), show that MOR208 is well tolerated with a low level of infusion reactions and demonstrates encouraging single-agent efficacy.
"The data we have generated so far in NHL, which included four complete responses in total, provide strong support for the MOR208 program. The signal searching approach we applied to this study has identified in particular diffuse large B-cell lymphoma and follicular lymphoma as valuable development options for this compound. It is worth noting, that MOR208 is a naked antibody that was used as monotherapy in this trial. The very encouraging single-agent activity and solid safety profile bode well for future development," commented Dr. Arndt Schottelius, Chief Development Officer of MorphoSys AG.
The open-label, phase 2a, multicenter study was designed to assess the efficacy and safety of single-agent MOR208 in patients with diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), mantle cell lymphoma (MCL), and other indolent NHL (iNHL), who had received at least one prior rituximab-containing therapy. Patients were initially treated with a total of eight weekly doses of MOR208. Those with at least stable disease stayed on MOR208 treatment for an additional four weeks. After completion of these twelve weekly doses of treatment, responding patients (complete or partial response) received maintenance therapy until progression.
The study used a two-stage design. In stage 1, approximately ten patients were enrolled in each of the four NHL subtypes. The DLBCL and FL cohorts which saw two or more responses (complete or partial response) in stage 1 were expanded in stage 2. The data presented today at ASH summarizes efficacy and safety results for 89 patients enrolled as of 17 November 2014 in stages 1 and 2 of this trial.

MOR208 was granted orphan drug designation in DLBCL (US) and CLL (US and Europe) in 2014. Additionally, the FDA has granted fast track designation for the treatment of DLBCL.
