Sorry for the delayed response. I was recently laid off from a small biotech company in CT and now I have all sorts of free time on my hands...
As for elaboration of the differences between advanced searches using clinicaltrials.gov (heretofore abbreviated ct.gov) and advanced searches of clinical trials using fdable.com (heretofore abbreviated fd.com)...
here are the differences as they currently stand (both have their +s and -s).
"Search Terms" in ct.gov doesn't search all datafields for search terms. I forget which ones it does search for, but fd.com searches all that are publicly available.
ct.gov lets you filter for trials that have published results. fd.com does not (yet).
ct.gov doesn't let you filter by an assortment of trial statuses. fd.com does. (e.g. you can't use ct.gov to say, "I want trials that are "not yet recruiting"
the same holds true for filtering by study type. ct.gov only lets you filter by one study type at a time (e.g. expanded access). fd.com lets you filter by multiple study types (e.g., "I want clin trials that are either observational or interventional or expanded access")
ct.gov lets you filter by trial location. fd.com does not (yet).
ct.gov gives you a general filter of who's funding the study (e.g., industry or academia or the government, etc.). fd.com does not
ct.gov allows you to filter results by whether safety is one of the outcome measures. fd.com does not (yet).
ct.gov does NOT let you filter by the # of people enrolled in the trial. fd.com does.
ct.gov lets you filter by when the clinical trial information was *first* provided to ct.gov. fd.com does not.
ct.gov does NOT let you filter by the projected start and end dates of the trial. fd.com does.
that's all i can think of right now.
***if anyone knows of a job opening that pays roughly $2.5 million per year and is located in central Connecticut, and requires little to no effort and much joy, i'd love to hear about it and point out how immensely qualified I am.***
