Know when a trial or drug changes status.
Posolix is a real-time clinical trial and FDA approval tracker. Subscribe to an illness or a medication in the dashboard and get an email as soon as a new trial or approval comes out, or send every change to your own endpoint by webhook.
7-day free trial, then plans from $29 a month. See pricing.

The FDA also approved 24 new drug applications in the same period. Approvals aren't tied to a place, so they're not on the map.
Updated hourly. Sites close together share a dot, and a trial counts once per dot. Medications are the drugs, biologics and supplements a trial tests.
One feed for trials and approvals, three ways to use it.
Pick the conditions, sponsors, phases or drug classes you care about. Posolix tracks them and tells you what changed, not just what's there.
Webhooks
Subscribe with a filter and get a signed POST every time a matching record changes. Each event carries the before and after values, so you don't have to diff anything yourself.

Data coverage.
Three kinds of record, checked on a schedule, with published articles linked to the trials they're about. Every version is stored, so history builds up from the day we start tracking a record. Full details are in the API docs.
| Data | What we track | Events | Checked | History |
|---|---|---|---|---|
| Clinical trials | Every registered US study: status, phase, enrollment, dates, sites and results | trial.* (6 types) | At least daily | Every version from when we start tracking |
| Drug approvals | Drug applications (NDA, ANDA, BLA), their products and submissions | drug.approved, drug.supplement_approved | At least daily | Full submission history as published by the FDA |
| Drug labels | Prescribing information by SPL set ID, section by section | label.updated, label.boxed_warning_changed | At least daily | Every version from when we start tracking |
| Published articles | Journal articles the trial registry links to a trial, or that name its ID in their abstract, with retractions flagged | None: shown on the trial, no alerts | Daily; retractions weekly | Current links only |
Check frequency is our target at launch. FDA changes can take a few days to show up.
Search every trial and approval, then subscribe to what you care about.
Search for an illness or a medication, narrow it down by phase, sponsor or status, and hit Subscribe. From then on we'll email you whenever a matching trial is registered, changes status or a drug is approved.

Questions.
What do I get?
Every plan includes a login to the search dashboard and email alerts. The API and Team plans add an API key for webhooks and the historical API. We're still early, so expect some changes while we learn what you need.
How do I get in?
Create an account with your email address. Your 7-day free trial starts right away, with the dashboard, email alerts and an API key. No card needed.
Can I get notified about a specific illness or medication?
Yes. Search for it in the dashboard, add filters like phase or sponsor if you want, and click Subscribe. We'll email you when a matching trial is registered or changes status, or when a matching drug is approved. Developers can have the same alerts sent to their own endpoint as webhooks.
Does every drug have a dashboard?
Not every one. A drug gets a dashboard once a trial, FDA application or label names it and RxNorm, the US standard drug vocabulary, recognizes the name. Many experimental compounds aren't there yet, and Drugs@FDA leaves out most vaccines, blood products, and cell and gene therapies. You can still search for any of them by name in the dashboard.
Can I see what's been published about a trial?
Yes, when we can find it. Each trial links to journal articles the trial registry connects to it, or that name its ID in their abstract, and flags any that were retracted. We link to the article rather than reproduce it, and not every trial has one.
How much does it cost?
Every account starts with a 7-day free trial, no card needed. After that, plans start at $29 a month for alerts and $149 a month for the API and webhooks. See pricing.
How fresh is the data?
We check for updates on a regular schedule and send emails and webhooks as soon as we detect a change.
Can I use this for medical decisions?
No. Posolix is a data and notification service, not medical advice. Always verify a record independently before acting on it.
