NCT ID NCT03903016

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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study compares two versions of insulin lispro—one standard strength and one double-strength—to see if they work the same in the body. About 90 adults with type 1 diabetes will receive a single dose of each in random order. The goal is to check if the stronger formula is bioequivalent, meaning it could offer a convenient alternative without changing how the drug works.

What this could mean

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

Active substance
insulin lispro
What this could lead to
If successful, this could confirm that a more concentrated insulin lispro is as effective as the standard version, offering more dosing options for people with type 1 diabetes.
What could go wrong
This is an early-phase study focused on bioequivalence, not on long-term outcomes or safety. It may not translate to real-world benefits or detect rare side effects.
