Innovative Drug Development Initiative (IDDI) Workstreams 

The IDDI is a global, collaborative forum where representatives from academia, the pharmaceutical industry (established and emerging biotechnology), and drug regulators openly discuss questions surrounding the future of trials involving novel drugs. See our IDDI Special collection on Clinical Trial Design: Past, Present, and Future.

We believe in the power of early and ongoing dialogue with all stakeholders in the drug development process, including the crucial perspective of patients and their advocates. The IDDI aspires to explore novel approaches for combating and treating PVD and PH, focusing strongly on patient needs. There are eight IDDI Workstreams, each assigned to address various challenges PH patients face.  

Task Forces 

Our Disease and Specialty Task Forces focus on research into specific areas of PVD. They support us in understanding and implementing our vision and mission. Our Regional Task Forces focus on the key challenges facing patients, clinicians and researchers in their country or region. Several Regional Task Forces were impacted by the Covid pandemic and are currently inactive, but some are in the process of re-forming, such as the South East Asia Task Force and China Task Force. 

Find out more about each IDDI Workstream or Task Force below. PVRI members who are interested in contributing are encouraged to join.
