About IMPALA

IMPALA is a randomized, international, multicenter, open-label phase III trial. The study aims to prove that a switch maintenance therapy with an active immunotherapy leads to an increased overall survival of patients who have achieved a response during their first line treatment of metastatic colorectal cancer. The primary endpoint is overall survival and secondary study endpoints include progression-free survival, toxicity and safety, and Quality of Life (QoL). Approximately 540 patients from more than 100 European centers, including the five major pharma markets, will participate in the study. IMPALA started to treat the first patients in mid-September.

Leading medical associations will participate: Arbeitsgemeinschaft Internistische Onkologie (AIO) in Germany, Grupo Españiol de Tratamiento de Tumores Digestivos (TTD) in Spain and Groupe Coopérateur Multidisciplinaire en Oncologie (GERCOR) in France. The steering committee consists of international medical experts; among others the coordinating study investigators Prof. David Cunningham, MD, Department of Medicine and Director of Clinical Research, Royal Marsden Hospital in London, and Prof. Dirk Arnold, MD, Director of the Clinic for Medical Oncology, Klinik für Tumorbiologie, Freiburg, Germany.
