HLH Study (Registry in cooperation with the Histiocyte Society)

The primary goal of the HLH Registry Study in Cooperation with the Hstiocyte Sciety is to collect data relevant for assessment of feasibility and design of future interventional studies on the treatment of HLH. This requires a detailed analysis of the target patient population treated by centers potentially participating in such studies. Another important goal of implementing a HLH Registry is to improve the network of physicians collaborating on HLH and to prepare the infrastructure for a future trial. Implementing routines for patient identification (and central notification), diagnostic algorithms and the use of a GCP database that is fully adapted to running interventional clinical trials are important milestones in facilitating the execution of a clinical trial.
