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 This study
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
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 Results may not be published yet.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

Summary

This study tests a personalized antisense oligonucleotide drug designed for a single person with ALS caused by a specific TARDBP gene mutation. The drug aims to reduce harmful TDP-43 protein and slow disease progression. The participant's clinical function, survival, and biomarkers are monitored over 12 months.

What this could mean

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

Active substance
a personalized antisense oligonucleotide drug called nL-TARDB-002
What this could lead to
If successful, this approach could slow or halt ALS progression in people with this specific genetic cause, offering a targeted treatment option.
What could go wrong
This is an early, single-participant study, so results may not apply to others. The drug may not work or could cause side effects.
