What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study uses healthcare claims data from nearly 24,000 people to see if it can reproduce the results of the EMPEROR-Reduced trial, which tested the diabetes drug empagliflozin against sitagliptin in heart failure patients. The goal is not to test a new treatment, but to learn whether real-world data can reliably mimic clinical trials. If it works, it could pave the way for faster, cheaper research using existing health records.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Empagliflozin and sitagliptin
What this could lead to
If successful, this could show that analyzing real-world data can reliably reproduce results from expensive clinical trials, making future research faster and cheaper.
What could go wrong
This is an observational study, not a controlled experiment, so results may be biased or not match the original trial. It only looks at existing records, not new treatments.

This is an AI summary of the original study and may miss details. Read our disclaimer.
