What the Pipeline for National Institute on Aging (NIA) Shows

According to the ClinicalTrials.gov registry, National Institute on Aging (NIA) is linked to 127 US clinical trials across every stage of research activity. Of those, 105 studies are currently recruiting — about 83% of the sponsor's indexed portfolio — and 19 are already marked complete, representing roughly 15% of the total. Recruiting share is one of the more practical signals here: it reflects how much of a sponsor's research is presently open to new participants, while the completed share indicates the depth of finished work that has already contributed registry results. Both counts come directly from the public ClinicalTrials.gov dataset and are refreshed on the registry side; this page mirrors the latest data pull without altering it.

The phase mix for National Institute on Aging (NIA) reports 3 late-stage studies (Phase 3 and Phase 4 combined) and 8 earlier-phase studies (Phase 1 and Phase 2). A portfolio weighted toward Phase 3 usually reflects an organization advancing candidates toward regulatory review, where the research centers on comparative efficacy and broader safety across larger populations. A heavier Phase 1 and Phase 2 tilt generally indicates exploratory work — safety, dosing, and early signal detection — and is common among research-forward sponsors that seed many early programs. Phase 4 entries, when present, track interventions already in real-world use and typically focus on long-term safety, effectiveness across subgroups, or formulation comparisons.

The top therapeutic focus area indexed for National Institute on Aging (NIA) is Aging with 7 linked trials, and 9 other condition areas appear in the top list above. That distribution is a quick read of where the organization concentrates its research attention; it does not imply product availability, market share, or any clinical endorsement. All numbers on this page come from ClinicalTrials.gov maintained by the National Library of Medicine, and counts can shift as new studies are registered or existing ones update their status.
