clinicaltrials.gov let's you save a search term then download the results as a zip. But there's an xml file for each search result for the trial.

One of the first things I played around with was using Python to get that file, unzip it, then iterate through the xml files grabbing the info I wanted and putting it into ElasticSearch to make it searchable then putting an angular front end on it.

I used to have it published somewhere but I think I let it all die. :(
