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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 early-stage trial is testing whether a special type of immune cell, called regulatory T cells (Tregs), is safe for people with ALS. The cells are taken from each patient's own blood, multiplied in a lab, and then injected into the spinal fluid. The study will enroll 12 adults with ALS to check for side effects and find a safe dose.

What this could mean

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

Active substance
regulatory T cells (Tregs) made from the patient's own blood
What this could lead to
If safe, this could point toward a new way to slow or manage ALS by calming the immune system.
What could go wrong
This is a very early, small safety trial with only 12 people. It may not show any benefit, and side effects from the cell injection or the procedure itself are possible.

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

Inclusion Criteria: \- Patients must meet all of the following criteria to be eligible for enrollment in this study: 1. Male or female patients aged 18 to 70 years; 2. According to current international diagnostic criteria: ALS: defined by the Gold Coast Diagnostic Criteria (Shefner, 2020) as having a diagnosis of sporadic or familial amyotrophic lateral sclerosis (ALS), diagnosed as a probable, probable, or definite patient with laboratory support according to the World Federation of Neurology El Escorial criteria; 3. If there is a stable dose for more than one month prior to study entry. For example, patients with ALS can continue treatment with riluzole (Rilutek®) and/or edaravone (Radicava®); 4. Patients must have \> two weeks after the end of major surgery and after the completion of participation in other research trials; 5. Patients must have recovered from clinical toxicity (CTCAE \[5th Edition\] toxicity values have resolved to \< 2); 6. Serum creatinine less than or equal to 2.0 mg/dL; 7. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) \< 3 x upper limit of normal; 8. Bilirubin \< 1.5 (except Gilbert's disease); 9. Lung slow vital capacity (SVC) \> 70% of predicted normal; 10. No history of abnormal bleeding tendency; 11. Informed consent must be obtained prior to performing any study-related procedures that are not part of standard medical care, with the understanding that the participant may withdraw from the study without influence for the future medical care. Exclusion Criteria: \- Subjects with any of the following cannot be enrolled in this study: 1. uncontrolled infection; 2. \< 3 drugs do not adequately control hypertension; 3. Documented history of pulmonary embolism within 6 months of enrollment; 4. Clinically significant cardiology, defined as: myocardial infarction, NYHA-graded class III or IV heart failure, uncontrolled angina, severe uncontrolled ventricular arrhythmia, or ECG evidence of acute ischemia or abnormal conduction system within 6 months prior to enrollment; 5. Patients with a history of coronary artery bypass grafting or angioplasty will be evaluated by cardiology and considered on a case-by-case basis; 6. Seropositive for HIV, hepatitis B or hepatitis C; 7. Pregnant or lactating patients; 8. Patients of childbearing potential or males with partners of childbearing potential who are unwilling to use contraception; 9. Participation in any other interventional study; 10. Treatment with another investigational drug, biologic, or device within 30 days or 5 half-lives (whichever is longer) of the screening period. Patient participation in observational/non-interventional clinical studies will be discussed with the Medical Monitor; 11. Prior treatment with ALS gene or cell therapy; 12. History of clinically significant tumor, liver or kidney disease, or other uncontrolled disease; 13. presence of a feeding tube; 14. Current use of antipsychotics, antiepileptic drugs (except benzodiazepines, gabapentin, pre-Bahrain) or class 1 (e.g., flecainide) or class 3 (e.g., amiodarone) antiarrhythmic drugs; 15. Subjects who, in the opinion of the investigator, are at significant risk of suicide; 16. Other conditions that the investigator considers unsuitable for enrollment.
