What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 is testing whether temporary electrodes placed on nerves in the arm can help people with hand amputations control a prosthetic hand more naturally and feel sensations like touch and movement. Twenty-five adults with hand, forearm, or arm amputations will have the electrodes implanted for about 18 months. Researchers will measure how well participants can move a prosthetic hand and detect sensations from electrical stimulation.

What this could mean

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

Active substance
temporary nerve electrodes (FAST electrodes)
What this could lead to
If successful, this could lead to more natural, dexterous prosthetic hands that restore fine finger control and sensation for amputees.
What could go wrong
This is an early-stage, small trial (25 people) testing temporary implants. The electrodes are removed after 18 months, and it's unknown if the approach will work for daily use or for all amputation levels.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 25 people

The number the study aims to enrol. It can still change while the study runs.

Start date

Jun 2015

Expected to finish

Mar 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 95 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Criteria for Inclusion of Subjects: Hand, forearm and arm amputees: 1. Male or female, age 18 and older, of any race or ethnicity 2. Able and willing to sign Consent 3. Able and willing to participate in all study activities including implantation, testing and explantation of the study device. 4. Able to communicate effectively in English without an interpreter After preliminary screening subjects will be assessed for the following inclusion criteria: Overall and phantom pain are well-controlled and not incapacitating Criteria for Exclusion of Subjects: 1. If MR neurogram and EMG/NCS study show nerve or muscle dysfunction/injury at a higher level than anticipated based on the appearance of the physical amputation stump, the subject may be excluded from the study due to adverse neuromuscular anatomy which would preclude use of the proposed experimental electrode implants. The radiographs will be used to confirm suitability of the amputation stump configuration. If the bony anatomy of the amputation stump is found to be unsuitable, the patient may be excluded from the study. 2. Subjects who have a history of cardiac arrhythmia will be excluded from the study.
