Dataset Card for Clinical Trials's Reason to Stop

Dataset Summary

This dataset contains a curated classification of more than 5000 reasons why a clinical trial has suffered an early stop. The text has been extracted from clinicaltrials.gov, the largest resource of clinical trial information. The text has been curated by members of the Open Targets organisation, a project aimed at providing data relevant to drug development.

All 17 possible classes have been carefully defined:

Business_Administrative
Another_Study
Negative
Study_Design
Invalid_Reason
Ethical_Reason
Insufficient_Data
Insufficient_Enrollment
Study_Staff_Moved
Endpoint_Met
Regulatory
Logistics_Resources
Safety_Sideeffects
No_Context
Success
Interim_Analysis
