OpenTargets Clinical Evidence Dataset

This OpenTargets clinical evidence dataset represents a comprehensive collection of clinical trial data linking genetic targets to diseases, containing 32 structured columns that capture the complete lifecycle of clinical studies. The dataset is annotated with clinical trials' predicted stop reason and genetic evidence when available and was referenced in the Why Clinical Trials Stop: The Role of Genetics. The study analyzed 28,842 stopped clinical trials and demonstrated that genetic evidence significantly influences trial efficacy.

This dataset was generated with the 22.04 Open Targets Data with this script.

Tutorial

To access the dataset, you can use HF datasets:

from datasets import load_dataset

ds = load_dataset("opentargets/clinical_evidence")

# see first record
next(ds.iter(1))

Features

The dataset contains a lot of genetic and clinical features which can be used for ML modelling.
