Clinical Trials Research Database

ClinicalTrials.gov is a database of privately and publicly funded clinical studies conducted around the world, maintained by the U.S. National Library of Medicine (NIH/NLM). This comprehensive resource contains information on clinical trials for a wide range of diseases and conditions.

<p><br/></p>

This listing provides a Cortex Knowledge Extension allowing you to ask questions about clinical trials and research studies and get back summarized, cited answers in your AI assistant and agentic applications built on Snowflake Cortex AI.

<p><br/></p>

After getting this listing, you will find a new Cortex Search Service shared with your account. You can use natural language to draw answers from clinical trial content by either prompting the Cortex Agent API directly in SQL, using Cortex Search Playground, Snowflake Intelligence or creating a Streamlit in Snowflake. Find detailed steps on each of these options in [documentation](https://docs.snowflake.com/en/user-guide/snowflake-cortex/cortex-knowledge-extensions/cke-overview) and[ tutorials](https://docs.snowflake.com/en/user-guide/snowflake-cortex/cortex-knowledge-extensions/overview-tutorials).

Data Refresh Pipeline Details:

The listing reflects real-time refreshed data from ClinicalTrials.gov API and RSS feeds, with automated updates daily. The system ingests comprehensive clinical trial metadata including:

- Study descriptions and eligibility criteria
- Intervention and outcome measures
- Baseline characteristics and adverse events
- Sponsor and condition information
- Study status, phases, and demographics

<p><br/></p>

You can view the current list of clinical trials available in the listing by querying the view: clinical_trials_dt. The system includes automated incremental ingestion of new and updated studies based on RSS feed monitoring from ClinicalTrials.gov.

<p><br/></p>

The database currently contains comprehensive data from ClinicalTrials.gov with over 400,000 clinical studies from all 50 states and 220+ countries worldwide.
