Data
Refreshed daily from ClinicalTrials.gov

01 What it is

A daily tracker for clinical trials in GLP‑1/obesity, type 2 diabetes, and cholesterol. It shows what changed in each trial’s public record: status, enrollment, endpoints, and sites.

02 The problem

ClinicalTrials.gov shows a trial’s current record. When a sponsor changes the status, the enrollment number, or an endpoint, the page shows the new value, and you would have to remember the old one to notice.

03 How it works

Every day the pipeline saves a copy of the registry record for each tracked trial and compares it with the previous day’s copy. Each difference becomes a dated change event, such as a status change, an enrollment change, or a site added.

Trial pages also carry a short AI-written summary of the record, and those summaries are tested. 30 hand-written test cases and a set of automatic checks run on every data refresh. A summary that fails a check is not published. When a model provider is set up, a second AI model also scores each summary for accuracy and clarity.

04 What it does

  1. 01

    Collections

    Three collections of trials: GLP-1 and obesity, type 2 diabetes, and cholesterol. Each one shows its trials counted by phase and by status, with a table of every trial.

  2. 02

    Change history

    Every change the pipeline detects is recorded with its date and type: a new trial, a status change, an enrollment change, an endpoint change, a site added or removed, a date change, or results posted.

  3. 03

    Trial pages

    One page per trial with its record, its full change history, and a checklist of who can and cannot take part, built from the trial’s eligibility text.

  4. 04

    AI summaries

    A short plain-language summary of each trial, written by an AI model from the registry record only. The page tells readers to verify it on ClinicalTrials.gov.

  5. 05

    How the AI is checked

    A public page reports the latest test run: every test case, what the AI wrote, and the expected answer.

  6. 06

    Trials near a city

    A search for the cities where a collection’s trials are recruiting.

  7. 07

    Count check

    Every run compares its trial counts with ClinicalTrials.gov’s own totals for the same searches.

  8. 08

    Glossary

    A page that explains the terms used on the site.
