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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Systemic sclerosis can cause the skin of the fingers to become thick and tight, a condition called sclerodactyly. This can make it difficult to bend, straighten, and use the fingers. This study will evaluate whether intradermal injections of hyaluronidase (Amphadase) can improve hand mobility and function and will assess treatment-related side effects. Approximately 10 adults with systemic sclerosis and sclerodactyly affecting both hands will participate at Stanford University. For each participant, one hand will be randomly selected by coin flip to receive hyaluronidase injections, while the opposite hand will serve as an untreated control. Participants may receive up to four injection sessions at baseline and approximately months 1, 2, and 3. Both hands will receive the same home exercise guidance throughout the study. Participants will undergo assessments at baseline and months 1, 2, 3, and 6, including hand mobility and skin examinations, hand function questionnaires, and assessment of symptoms and adverse events. Researchers will compare changes between the treated and untreated hands. The investigator performing hand outcome assessments will be blinded to treatment assignment.

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

Inclusion Criteria: * Adults aged 18 years or older. * Documented diagnosis of scleroderma * Clinically evident bilateral sclerodactyly involving both hands, * Able and willing to comply with study visits and assessments. * Able to provide written informed consent. Exclusion Criteria: * Age younger than 18 years. * Unable to provide informed consent. * Absence of bilateral sclerodactyly sufficient to permit treatment and comparison. * Known hypersensitivity to hyaluronidase or any component of the study drug. * Active infection, acute inflammation, or another condition at a planned injection site that would make intradermal injection unsafe. * Pregnancy or anticipated pregnancy. * Declines participation.
