US FDA announces new evidence principles for very rare genetic diseases
A statement by a ministry, institution or international organisation, or a change in regulations. It is not evidence about how well a treatment works.
The US Food and Drug Administration (FDA) announced 'Rare Disease Evidence Principles' for genetic diseases that generally have fewer than 1,000 patients in the USA. Under these principles, approval may be assessed based on a single well-designed study plus supporting evidence. Additional follow-up may be required after approval.
What does it mean for patients and families?
The aim is to review new treatments for very rare diseases more quickly. This is a regulation specific to the USA.
