MARTINSRIED, Germany, June 29 -- The biotech company MediGene AG announces that a case report from the ongoing clinical trial of MediGene's cancer killing virus will be presented in a press conference held by the European Society for Medical Oncology. Out of more than 300 posters accepted for the conference, only five were chosen for presentation in the press conference.

The event will take place on Friday, July 6, at 12:30 MEST at the ESMO conference in Lugano, Switzerland (ECLU). Dr. Axel Mescheder, Head of Clinical Research and Development at MediGene, will present the data in the press conference as well as in a poster presentation during the conference.

The phase I/II trial of NV1020 for the treatment of liver metastases of colorectal cancer is being conducted at seven leading cancer centers in the US. In September 2006, MediGene announced positive safety and efficacy data from an interim analysis of this study. The poster presented at the ESMO conference shows efficacy data in a case study for the first time.

Dr. Ulrich Delvos, Chief Operating Officer of MediGene, comments. "We are delighted and proud that the European Society for Medical Oncology has decided to present a case study from our trial in a press conference. Considering the number of studies presented on Europe's largest cancer congress, this emphasizes the innovation and the potential of this approach to fight cancer."
