What the Pipeline for Gilead Sciences Shows

According to the ClinicalTrials.gov registry, Gilead Sciences is linked to 504 US clinical trials across every stage of research activity. Of those, 26 studies are currently recruiting, about 5% of the sponsor's indexed portfolio, and 346 are already marked complete, representing roughly 69% of the total.

The phase mix for Gilead Sciences reports 164 late-stage studies (Phase 3 and Phase 4 combined) and 317 earlier-phase studies (Phase 1 and Phase 2).

The top therapeutic focus area indexed for Gilead Sciences is HIV-1-infection with 20 linked trials, and 9 other condition areas appear in the top list above.

How to read these pipeline numbers

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.

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.

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. This information is provided for reference and educational purposes only, not as medical, investment, or regulatory advice, verify current details directly with ClinicalTrials.gov before relying on any figure here.
