clinicaltrials-completed-phase3-full — Data Card
Version: 1.1.0 | Generated: 2026-06-14T06:18:47.568731+00:00 | Records: 29,633
Dataset Summary
clinicaltrials-completed-phase3-full contains structured clinical trial records from ClinicalTrials.gov, the U.S. federal registry of clinical studies operated by the National Library of Medicine (NIH). Each record includes trial status, design parameters, eligibility criteria, sponsor information, enrollment counts, and primary outcome measures — extracted, normalized, and validated by the jade pipeline. Intended for clinical researchers, pharmaceutical data teams, market intelligence analysts, and quantitative healthcare investors.
Source
- Primary source: ClinicalTrials.gov, the U.S. National Library of Medicine's registry of clinical studies, operated by NIH. Accessed via the ClinicalTrials.gov REST API v2. Enrichment fields added post-hoc from the same source.
- Collection method: Automated pipeline using jade v0.1.0
- License: U.S. Government Open Data (Public Domain) — no restrictions on use or redistribution
- PII status: No personally identifiable information. Investigator contacts and patient-level data excluded at collection time.
Quality Metrics
- Dataset quality score: 0.9867 (threshold: 0.92)
- Validation layers: Pydantic schema · Business rules · Statistical checks · LLM cross-check
- Records passing validation: 29,633 of 29,633 in this version
Field Definitions
| Field | Type | Description |
|---|---|---|
| nct_id | str | ClinicalTrials.gov unique identifier (NCT######) |
| title | str | Brief title of the clinical study |
| official_title | str | None |
| status | str | Overall recruitment status (e.g. COMPLETED, RECRUITING) |
| start_date | str | None |
| completion_date | str | None |
| sponsor_name | str | Lead sponsor organization name |
| sponsor_class | str | None |
| conditions | list[str] | Medical conditions or diseases studied |
| study_type | str | None |
| phases | list[str] | Clinical trial phases (e.g. PHASE3) |
| enrollment | int | None |
| allocation | str | None |
| masking | str | None |
| interventions | list[dict] | Interventions with type, name, and description |
| primary_outcomes | list[dict] | Primary outcome measures with measure and time_frame |
| secondary_outcomes | list[dict] | Secondary outcome measures with measure and time_frame |
| minimum_age | str | dict |
| maximum_age | str | dict |
| sex | str | None |
| results_available | bool | Whether results have been posted to ClinicalTrials.gov |
| locations_count | int | None |
| countries | list[str] | Countries where the study is conducted |
| trial_duration_days | int | None |
| therapeutic_area | str | Disease area classification: Oncology, Cardiovascular, Neurology / CNS, Infectious Disease, Metabolic / Endocrine, Immunology / Rheumatology, Respiratory, Gastroenterology, Dermatology, Ophthalmology, Rare Disease / Orphan, Other. |
| primary_endpoint_met | str | Whether the primary endpoint was achieved: 'true', 'false', or 'unknown'. Coverage: ~45% of records (those with posted results on ClinicalTrials.gov). Extracted by LLM from the results section. |
Known Limitations
- Location data (countries, locations_count) is absent for approximately 15% of studies where ClinicalTrials.gov omits the contactsLocationsModule.
- sponsor_class may include values outside the standard set (e.g. 'OTHER') for a small fraction of records; these receive a statistical soft warning but are not excluded.
- Completion dates reflect the study's reported anticipated or actual completion, not verified outcomes.
- Age fields (minimum_age, maximum_age) are returned as parsed {value, unit} objects rather than plain strings.
- primary_endpoint_met is 'unknown' for ~55% of records where ClinicalTrials.gov has not yet posted results. This is expected — results are posted voluntarily and often lag trial completion.
- therapeutic_area is LLM-assigned and may differ from formal MeSH classification for trials spanning multiple disease areas.
