Intrathecal Autologous Adipose-derived Mesenchymal Stromal Cells for Amyotrophic Lateral Sclerosis (ALS)

A Phase II Study of Intrathecal Autologous Adipose-derived Mesenchymal Stromal Cells for Amyotrophic Lateral Sclerosis

Source: ClinicalTrials.gov · Last updated 9 Mar 2026

Brief summary (registry, in English)

The purpose of this study is to determine the safety and efficacy of intrathecal treatment delivered to the cerebrospinal fluid (CSF) of mesenchymal stem cells in ALS patients every 3 months for a total of 4 injections over 12 months. Mesenchymal stem cells (MSCs) are a type of stem cell that can be grown into a number of different kinds of cells. In this study, MSCs will be taken from the subject's body fat and grown. CSF is the fluid surrounding the spine. The use of mesenchymal stem cells is considered investigational, which means it has not been approved by the Food and Drug Administration (FDA) for routine clinical use. However, the FDA has allowed the use of mesenchymal stem cells in this research study.

Who cannot take part

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • Current use of immunosuppressant medication or use of such medication within 4 weeks of Screening visit (Visit 1).
  • Malignancy 5 years prior to enrollment, including melanoma,with the exception of localized skin cancers (with no evidence of metastasis, significant invasion, or re-occurrence within three years of baseline).
  • Inability to lie flat for the duration of intrathecal cell transplantation, or inability to tolerate study procedures for any other reason.
  • Use of herbal medications, nutritional supplements or other unapproved drugs or investigational medicinal products being used or studied for the treatment of ALS.
  • Enrolled in an investigational drug trial within 30 days of baseline visit
  • Prior stem cell therapy for a neurological disease
  • Chronic low back pain requiring invasive procedures (i.e. epidural injections or lumbar spine surgery)

Other illness

  • Any clinically significant medical condition (e.g., within six months of baseline, had myocardial infarction, angina pectoris, and/or congestive heart failure) that, in the opinion of the investigator, would compromise the safety of patient.
  • Autoimmunity, including Crohn's disease or rheumatoid arthritis
  • Active systemic or local infection near the lumbar puncture site.

Lab values

  • Other active systemic disease as defined by laboratory abnormalities delineated in Appendix IV.

Age

  • Pulmonary Slow Vital Capacity (SVC) less than 65% of predicted for age, gender, and body type.

Other

  • Use of Radicava® (edaravone) within 30 days of screening or intent to use Radicava® at any time during the course of the study including the follow up period.
  • Unwilling to forgo initiating the use of any new supplements during participation in the study.
  • Kokmen Short Test of Mental Status score \<32
  • Presence of a tracheostomy
  • Ventilator dependent
  • Pregnancy
  • Men or women of childbearing potential who are unwilling to employ adequate contraception

Who the study is looking for

  • All patients will have ALS diagnosed as possible, laboratory-supported probable, probable, or definite as defined by the World Federation of Neurology criteria for the diagnosis of ALS.
  • Examination and neurophysiological testing confirm a pure motor syndrome compatible with the diagnosis of ALS. All other possible causes of weakness have been excluded by extensive investigations.
  • Age greater than 18 years, if female, must be post-menopausal, had a hysterectomy, or agree to two forms of birth control.
  • Permanent resident or citizen of the United States.
  • Geographic accessibility to the study site and willingness and ability to comply with follow-up.
  • History of a chronic onset of a progressive motor weakness of less than two years duration.
  • Subjects must be taking a stable dose of riluzole for at least 30 days prior to enrolment or not be on riluzole, and not have been on it for at least 30 days prior to enrolment (riluzole-naïve subjects are permitted in the study).
  • Subjects must be taking a stable dose of oral Radicava® (edaravone) for at least 30 days prior to enrolment or not be on oral Radicava® (edaravone), and not have been on it for at least 30 days prior to enrolment (edaravone-naïve subjects are permitted in the study).
  • Able to comply with protocol requirements, including MRI testing.
  • Can provide written informed consent.
