Research initiatives
Although research is not the principal scope of ERNs, ERN BOND acts in order to facilitate research and clinical trials among members. This section illustrates the research initiatives endorsed by the network.
Clinical Trials & Research Studies
ERN BOND by liaising with relevant stakeholders, collects and disseminate to BOND members the information and activities with the aim to facilitate the good clinical trial conduct for Rare Bone Disorders.
ERN BOND supports also the development of investigator led studies in rare bone disorders, covering both clinical trials of investigational medical products and research studies not involving drugs.
In the past, the thematic group on Clinical Trials supported the development and conduction of a studies involving BOND expert centres to:
- validate the existing paediatric Osteogenesis Imerfecta Quality of Life tools
- and to, ascertain child and parent priorities for research in Osteogenesis Imperfecta.
Two clinical trials, under EU projects, are currently endorsed by ERN BOND and conducted by network members.
- MCDS-Therapy, an open label phase I/II a trial repurposing carbamazepine (CBZ) for the treatment of children with metaphyseal chondrodysplasia, Schmid type (URL),
- MOI-A study, a matrix-directed therapy in older adolescents and adults with osteogenesis imperfecta, within the REMEDI4ALL project.
- Together4RD, is an agile multi-stakeholder initiative aimed at supporting ERNs to collaborate with stakeholders to pursue opportunities that will address unmet medical needs of people living with rare diseases.
- RealiseD: the project aims to tackle these issues by developing new tools, methods, and systems that make clinical trials for rare diseases more efficient, accessible, and patient-focused.
