How this issue is made

Every trial change comes from ClinicalTrials.gov, read twice a day for the conditions Trial Friend follows, and every FDA decision, designation and label change from the FDA's own records, Drugs@FDA and openFDA, read daily. Each line links to the page that holds its source. The issue is assembled on the Monday after the week and does not change afterwards, except to correct an error, which is noted on the page. Counts cover only the rare conditions on this site, so they are a floor for rare disease as a whole, not a total. Nothing here is medical advice.
