"The German Institute for Quality and Efficiency in Health Care (IQWiG) already assessed the added benefit of ipilimumab in advanced melanoma in 2012. A considerable added benefit was found for patients who had already received previous treatment. In the new dossier compiled by the drug manufacturer, the drug was now compared with the appropriate comparator therapy dacarbazine specified by the Federal Joint Committee (G-BA) also for non-pretreated patients."
Editor's Note: This story is a little confusing, so here is a summary to clarify: It was already known that ipilimumab can be beneficial for people who have received previous treatment for melanoma. A new study aimed to find out if ipilimumab also improves survival for patients who have not received prior treatment. However, for a variety of reasons, the study did not show that ipilimumab performs any better than dacarbazine in patients who have not received prior treatment.
