Mologen AG Announces Successful Course of Study of Cancer Drug MGN1703

BERLIN, Jan. 14, 2009--The Berlin biotech company MOLOGEN AG has had good results so far in a clinical study with the cancer drug MGN1703. The safety and efficacy of MGN1703 are currently under investigation in a phase I trial.

MGN1703 has demonstrated a favorable safety profile and good tolerability thus far. The dosing regimen specified in the study plan could therefore be followed without modification. Patients were initially treated with single doses of the drug. Based on good tolerability, when the single treatment was over, all patients were switched to a higher dose involving multiple administrations for a longer period. Currently the last patient group is going to be included and will be treated according to the highest dosing regimen planned.

Assuming the trial continues to proceed according to plan, MOLOGEN expects to finish the treatments at the end of the first quarter of 2009.

In consideration of the favorable progress and imminent completion of the study, MOLOGEN is currently intensively engaged in preparing additional clinical trials investigating the efficacy of MGN1703 (phase II).

Dr. Matthias Schroff, CEO of MOLOGEN AG, said: "We are extremely pleased with the progress of the study so far and the safety profile of MGN1703. When the current treatments are finished, we want to start additional studies on MGN1703 as soon as possible in order to investigate the drug's efficacy potential in the treatment of various cancers."

Information about the clinical study with MGN1703

The study (Phase I) of the safety, compatibility and immunological effect of MGN1703 in the treatment of various cancers is a major milestone for a comprehensive clinical development program. The study is currently performed at the renowned cancer centers in university hospitals in Essen and Cologne. MOLOGEN plans to establish an effective, compatible treatment for the treatment of the most frequent cancers in the form of MGN1703.

dSLIM® - an innovative TLR9 agonist In dSLIM® ("double Stem Loop Immunomodulator"), MOLOGEN has developed an innovative TLR9 agonist. Use of dSLIM® activates the immune system against tumor-associated antigens by targeting the different receptors, primarily TLR9, on certain immune cells. As a result of chemotherapy and radiotherapy, tumor-associated antigens (TAA) are released by cancer cells. The immune system activated by dSLIM® is in a position to overcome its fatal tolerance towards cancer cells and TAA and advance against them strategically.
