Sponsor Debt Dashboard

Sponsor overdue debt shows which portfolios keep the oldest unresolved CT.gov backlog alive

GlaxoSmithKline holds the largest sponsor overdue debt, Boehringer Ingelheim stays close behind and also leads on mean unresolved age among the biggest debt holders, NCI remains prominent, and Sanofi and AstraZeneca stay in the top tier on chronic backlog.

GlaxoSmithKline holds the largest sponsor overdue debt, Boehringer Ingelheim combines very high debt with the heaviest mean unresolved age, and NCI remains a major public-sector debt holder.

Top sponsor overdue debt

GlaxoSmithKline, Boehringer Ingelheim, NCI, Sanofi, and AstraZeneca dominate the sponsor debt table.

That is the chronic-stock view of the sponsor backlog.

Mean unresolved age

Boehringer Ingelheim and several smaller but still sizeable sponsor portfolios carry extremely old unresolved studies.

Debt stock and mean age need to be read together.

Top sponsor missing-results stock

The same sponsors driving overdue debt also hold very large raw missing-results stock.

That is why the sponsor debt table extends rather than replaces the count table.
