The document discusses the evolving role of patient advocacy groups in orphan drug development. It notes that historical barriers to orphan drug research included limited funding, lack of researcher interest, and few patient groups. The 1983 Orphan Drug Act and similar European regulations aimed to incentivize orphan drug development by providing tax credits, reduced fees, and extended market exclusivity for sponsors. Both the FDA and EMA have increasingly engaged with patient groups over the past few decades. Industry and patient groups both seek collaboration to advance research, though their needs differ. Frameworks like the EFPIA and CTTI guidelines provide recommendations for transparent and ethical partnerships between stakeholders.
