Medigene AG (FSE: MDG1, Prime Standard, TecDAX) today announced that all planned patients have been enrolled in the Company's ongoing Phase I/II study with dendritic cell (DC) vaccines in acute myeloid leukaemia (AML). The completion of the study, as previously announced, is expected in 2019 after a treatment period of two years for all patients.

Medigene's Phase I/II trial (NCT02405338) includes 20 AML patients who show complete remission after standard chemotherapy, but who are not eligible for stem cell transplantation that would reduce the risk of a relapse. All patients will be vaccinated with Medigene's DC vaccines for two years. The primary objective is to assess safety and feasibility of the active immunotherapy with Medigene's dendritic cells. Secondary objectives of the study are induction of immune responses, overall survival (OS), progression free survival (PFS), control of minimal residual disease (MRD) and time to progression (TTP).

Dr. Kai Pinkernell, SVP Clinical Affairs and Chief Medical Officer of Medigene AG, comments: "With this study we aim to improve the outcome of the patients and show that vaccination with dendritic cells can help to control AML, a leukemia with normally high relapse rates. We are glad to announce the complete enrollment of our phase I/II trial as projected, which puts us on track for a study end in 2019. We intend to provide preliminary data on certain aspects of the trial at scientific conferences once a large part of the patients has been treated for more than a year."

About Medigene's DC vaccines:

The platform for the development of antigen-tailored DC vaccines is the most advanced of Medigene's highly innovative and complementary immunotherapy platforms. Currently Medigene evaluates its DC vaccines in a company-sponsored Phase I/II clinical trial in acute myeloid leukaemia (AML).

Dendritic cells (DCs) are the most potent antigen-presenting cells of our immune system. Their task is to take up, process and present antigens on their cell surface, which enables them to activate antigen-specific T cells for maturation and proliferation. This way T cells can recognize and eliminate antigen-bearing tumor cells. Dendritic cells can also induce natural killer cells (NK cells) to attack tumor cells. The team of Medigene Immunotherapies scientists has developed new, fast and effective methods for generating dendritic cells ex-vivo, which are able to activate both T cells and NK cells. The DC vaccines are developed from autologous (patient-derived) precursor cells, isolated from the patient's blood, and can be loaded with tumor-specific antigens to treat different types of cancer. Medigene's DC vaccines are in development for the treatment of minimal residual disease or for use in combination therapies.

About acute myeloid leukaemia (AML):

Acute myeloid leukaemia is a malignant disease of the hematopoietic system, affecting mainly adults above 60 years of age. In Germany, about 3,600 incidences are registered annually.

AML is caused by uncontrolled growth of dysfunctional hematopoietic precursor cells in the bone marrow. These cells prevent the generation of normal blood cells, causing a drop in erythrocytes and platelets, for example. Typical symptoms of AML include anemia, fever, increased risk of infection, and blood coagulation disorder. AML progresses rapidly and may be fatal within a few weeks if untreated.

AML is treated initially with intensive chemotherapy. Another treatment option is allogeneic hematopoietic stem cell transplantation. Unfortunately, the majority of patients suffer a relapse. Only about 15 - 20% of the patients show long-term remission after conventional chemotherapy. Allogeneic hematopoietic stem cell transplantation is the only treatment option that offers a more positive prognosis.

Medigene AG (FSE: MDG1, ISIN DE000A1X3W00, Prime Standard, TecDAX) is a publicly listed biotechnology company headquartered in Martinsried near Munich, Germany. The company is developing highly innovative immunotherapies to target various forms and stages of cancer. Medigene concentrates on the development of personalized T cell-based therapies, with associated projects currently in pre-clinical and clinical development.
