Provenance
Where these numbers come from
Large company small molecule share of Phase I clinical trial starts
Percentage of Phase I clinical trial starts sponsored by large pharmaceutical companies that investigate small molecule drugs.
2 observations charted in Global · source organisations: IQVIA
Alzheimer's disease drug trial starts
Count of interventional drug or biologic studies in Alzheimer's disease whose start date falls in the period. The region is a site country: a study counts for every country where it lists a site, so regional counts overlap and do not sum to the global count.
