Subarachnoid Hemorrhage clinical trials
The registry lists 510 studies for Subarachnoid Hemorrhage across more than 10 countries. 128 are recruiting or about to start. 335 of them are mainly about Subarachnoid Hemorrhage (how this is decided). Per ClinicalTrials.gov, last updated 2026-11-12.
ClinicalTrials.gov finds 573 studies for Subarachnoid Hemorrhage. How that becomes 510 here
This page counts the studies the registry files under Subarachnoid Hemorrhage, and those it files under no condition that list Subarachnoid Hemorrhagethemselves. Each study its search finds is placed by how the registry filed it and by the conditions it lists. ClinicalTrials.gov counts as of Nov 8, 2026. How condition pages count
- 573Found by its condition searchIt reads the conditions a study lists and their synonyms, and also titles and keywords.
- −5List Subarachnoid Hemorrhage as a condition, but the registry did not file them under itMost often written as “Aneurismal Subarachnoid Hemorrhage” (1), “Aneurysmal Subarachnoid Hemorrhage, Familial” (1), and “Post-Traumatic Subarachnoid Hemorrhage” (1). The registry filed them under other conditions only, most often Subarachnoid Hemorrhage, Traumatic (2) and Hypopituitarism (1).
- −58Match it another way41 name it in the title, 1 in a keyword, and 16 by a synonym or other text the search reads.
- 510The count on this page4 of them list Subarachnoid Hemorrhage in their own words; the registry filed them under no condition.

How long Subarachnoid Hemorrhage studies take
Of 119 observational studies under Subarachnoid Hemorrhage, half reached primary completion within 40 months of starting, counting those still running.
| Start to primary completion | Every sponsor | Industry | Non-industry |
|---|---|---|---|
| Interventional, no phase | 32 mo20–60 · 67 studies | — | 38 mo24–62 · 57 studies |
| Observational | 40 mo19–127 · 119 studies | — | 40 mo21–127 · 116 studies |
Each figure is the month by which half the studies had reached primary completion, with the range in which the middle half did. Studies still running count until their last registry update; studies that stopped early are left out. Phase 1 includes early phase 1; observational means prospective or not stated, as retrospective and cross-sectional studies date a window of data rather than a study. How these figures are worked out
