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
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 Results may not be published yet.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) This study
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This status has not been confirmed recently, so it may be out of date.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 trial provides expanded access to RAPA-501, a therapy made from a patient's own immune cells, for people with ALS. The goal is to control the disease and slow its progression. Participants must be 18 or older and have a confirmed ALS diagnosis.

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

Inclusion Criteria: 1. Male or female patients ≥ 18 years of age. 2. Patients with sporadic or familial ALS diagnosed as laboratory-supported possible, probable, or definite according to World Federation of Neurology El Escorial Criteria. 3. Pulmonary slow vital capacity (SVC) \< 50% of predicted normal (as measured within three months prior to screening or at the time of screening; inability to measure an SVC value at the time of screening that is due to severe reduction in respiratory function will also fulfill this eligibility criterion #3). However, SVC values ≥50% are acceptable if an EAP recipient of RAPA-501 is re-enrolled to the study. 4. Must have a source of autologous T cells potentially sufficient to manufacture RAPA-501 cells, as defined by a peripheral CD3+ T cell count ≥ 500 cells per μl. 5. Patients who are taking riluzole (Rilutek®), edaravone (Radicava®), and/or sodium phenylbutyrate/taurursodial (Relyvrio™) are eligible if taking the drug for at least 30 days prior to the screening visit. 6. Patients must be ≥ two (2) weeks removed from major surgery, or investigational therapy. 7. Patients must have no ongoing, unstable serious illness other than ALS, as determined by the Site Investigator. 8. Serum creatinine less than or equal to 2.0 mg/dL. 9. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3 x upper limit of normal (ULN). 10. Bilirubin ≤ 1.5 (except if due to Gilbert's disease). 11. No history of abnormal bleeding tendency. 12. Voluntary written consent must be given before performance of any study related procedure not part of standard medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to future care. 13. Not enrolled in another interventional clinical trial or expanded access protocol and must have stopped taking other experimental drug(s) at least 2 weeks prior to screening. Exclusion Criteria: 1. Active uncontrolled infection. 2. Hypertension not adequately controlled by ≤ 3 medications. 3. History of documented pulmonary embolus within 6 months of enrollment. 4. Clinically significant cardiac pathology, as defined by: myocardial infarction within 6 months prior to enrollment, Class III or IV heart failure according to NYHA, uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities. 5. HIV, hepatitis B, or hepatitis C seropositive. 6. Pregnant or breastfeeding subjects. 7. Subjects of childbearing age, or males who have a partner of childbearing potential, who are unwilling to practice contraception. 8. Subjects may be excluded at the Principal Investigator discretion or if it is deemed that allowing participation would represent an unacceptable medical or psychiatric risk.
