A Phase 3 interventional study of Autologous Hematopoietic Stem Cell Transplantation and Best Available Therapy (BAT) in Relapsing Multiple Sclerosis, Relapsing Remitting Multiple Sclerosis and Secondary Progressive Multiple Sclerosis, sponsored by National Institute of Allergy and Infectious Diseases (NIAID). Recruiting at 23 sites in United States. Open to participants aged 18 Years to 55 Years. Per ClinicalTrials.gov, last updated 2026-10-20.

This is a multi-center prospective rater-masked (blinded) randomized controlled trial of 156 participants, comparing the treatment strategy of Autologous Hematopoietic Stem Cell Transplantation (AHSCT) to the treatment strategy of Best Available Therapy (BAT) for treatment-resistant relapsing multiple sclerosis (MS). Participants will be randomized at a 1 to 1 (1:1) ratio.
All participants will be followed for 72 months after randomization (Day 0, Visit 0).
Participant recruitment for this six-year research study focuses on multiple sclerosis (MS) that has remained active despite treatment. This study will compare high dose immunosuppression followed by autologous hematopoietic stem cell transplantation (AHSCT) to best available therapy (BAT) in the treatment of relapsing MS.
MS is a disease caused by one's own immune cells. Normally, immune cells fight infection. In MS, immune cells called T cells, or chemical products made by immune cells, react against the covering or coat (myelin) of nerve fibers in the brain and spinal cord. This leads to stripping the coat from certain nerve fibers (demyelination), and this causes neurologic problems. MS can cause loss of vision, weakness or incoordination, loss or changes in sensation, problems with thinking or memory, problems controlling urination, and other disabilities.
Most individuals with MS first have immune attacks (called relapses) followed by periods of stability. Over time, MS can have episodes of new and worsening symptoms, ranging from mild to disabling. This is called relapsing MS. Relapsing MS includes relapsing remitting MS (RRMS) and secondary progressive MS (SPMS). There are medicines (drugs) to decrease relapses, but these are neither considered to be curative nor, to induce prolonged remissions without continuing therapy.
More than a dozen medicines have been approved for the treatment of relapsing forms of MS. These medicines differ in how safe they are and how well they work. Despite availability of an increasing number of effective medicines, some individuals with relapsing MS do not respond to treatment. Research is being conducted to find other treatments.
High dose immunosuppression followed by autologous hematopoietic stem cell transplantation (AHSCT) has been shown to help relapsing MS in cases where medicines did not work. AHSCT involves collecting stem cells, which are produced in the bone marrow. These stem cells are "mobilized" to leave the bone marrow and move into the blood where they can be collected and stored. Participants will then receive chemotherapy intended to kill immune cells. One's own stored (frozen) stem cells are then given back, through an infusion. This "transplant" of one's stem cells allows the body to form new immune cells in order to restore their immune system. New research suggest that MS might be better controlled with AHSCT than with medicines.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
From a breathing test (spirometry): how much air you can blow out in the first second. Often given as a percentage of what is expected for your age, height and sex.

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.
Stroke symptoms need emergency care at once, even if they go away.
