Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
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 Results may not be published yet.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

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 trial tests whether an experimental drug called KM04 is absorbed and cleared by the body in the same way as the approved fertility drug Gonal-f. Healthy adult women aged 18 to 40 receive a single dose of each drug in random order, with blood samples taken to compare drug levels. The goal is to see if KM04 could be a similar alternative to Gonal-f.

What this could mean

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

Active substance
KM04, an experimental version of the fertility drug follitropin alfa (Gonal-f)
What this could lead to
If KM04 behaves like Gonal-f in the body, it could become a more affordable or accessible fertility treatment option.
What could go wrong
This is an early, small study in healthy volunteers, not people with fertility issues. Even if the drug matches in healthy women, it may not work the same in patients, and the trial does not test effectiveness.
