Eligibility Criteria
You may qualify if:
- Diagnosis of RMS according to the 2024 McDonald Criteria (Montalban et al 2025) or diagnosis of relapsing, active SPMS according to Lublin et al 2014.
- Participants should have an EDSS of ≤ 6.5 at screening.
- Evidence of active disease (clinical relapses and MRI activities within 2 years prior to screening), or intolerance, while on a high efficacy disease-modifying therapy for ≥ 6 months.
- Diagnosis of PPMS according to the 2024 McDonald Criteria (Montalban et al 2025) or non-relapsing SPMS according to Lublin et al 2014.
- Participants must have an EDSS of ≥ 3.0 and ≤ 6.5 at screening.
- Inadequate response ≥ 1 heDMT with ≥ 6 months treatment or intolerance.
You may not qualify if:
- Participants are excluded from the study if any of the following criteria apply:
- Any prior CAR-T or CAR-NK cell exposure.
- Underwent splenectomy within 12 months prior to signing the ICF.
- Received a solid organ transplant at any time or on an active transplant waiting list.
- Prior treatment with autologous hematopoietic stem cell transplantation or total lymphoid irradiation.
- Cardiac conditions or any other significant cardiac condition that would present undue risk to the participant in the investigator's opinion:
- Any other central nervous system disease including epilepsy, convulsive seizures, organic encephalopathy syndrome, non-MS related paralysis, aphasia, stroke, severe brain injury, dementia, Parkinson's disease or associated movement disorder, psychosis, CNS vasculitis, or any other neurological disease that may impact the ability to evaluate neurotoxicity. History of a seizure disorder even if the seizure disorder is well controlled with anti-epileptics.
- Participant has significant psychiatric condition (active or history of).
- History of other immune-mediated disease that required continued systemic immunosuppression/systemic disease-modifying agents.
- Evidence of clinically significant bleeding or active bleeding diathesis within 90 days before screening
- History of malignancy or ongoing treatment for prior malignancy.
- Inborn error of immunity and/or primary immunodeficiency.
- Seropositive for HIV or HTLV (including any history of HIV or HTLV).
- Active viral (any etiology, HBV, HCV) hepatitis are excluded.
- Major surgery within 4 weeks prior to apheresis or lymphodepletion or has surgery planned during the study or within 4 weeks after study treatment administration.
- +4 more criteria
