Know when a trial or drug changes status.
Posolix watches US clinical trials and FDA drug approvals. 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.
Beta members get an API key and a dashboard login, free for the length of the beta.
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.

Search dashboard
Browse the same data without writing code. Subscribe to any illness, medication or search and get an email when something new comes out.
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 does the beta include?
Full access to both halves of Posolix: an API key for webhooks and the historical API, and a login to the search dashboard. Expect rough edges and some changes while we learn what you need.
How do I get in?
Fill in the short request form. We're letting people in in small groups and will email you your API key and dashboard login when your spot opens.
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.
How much will it cost?
Nothing during the beta. Beta users will hear about pricing before it starts and get early-supporter terms.
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.
