Brief summary
This trial is a Phase 1b, open-label, multi-center, clinical study of AZD0120, a BCMA/CD19 dual targeting CAR+ T-cell therapy, to evaluate the safety and tolerability in adult participants with Multiple Sclerosis.
Detailed description
This study will evaluate AZD0120 for safety, including DLTs and TEAEs, by the SRC for determination of the Recommended Phase 2 dose for each disease cohort. Approximately 9-12 participants will be evaluated per disease cohort.
Interventions
Regimen 1, infusion of AZD0120
Regimen 2, infusion of AZD0120

Exclusion criteria
Participants are excluded from the study if any of the following criteria apply: 1. Any prior CAR-T or CAR-NK cell exposure. 2. Underwent splenectomy within 12 months prior to signing the ICF. 3. Received a solid organ transplant at any time or on an active transplant waiting list. 4. Prior treatment with autologous hematopoietic stem cell transplantation or total lymphoid irradiation. 5. Cardiac conditions or any other significant cardiac condition that would present undue risk to the participant in the investigator's opinion: 6. 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. 7. Participant has significant psychiatric condition (active or history of). 8. History of other immune-mediated disease that required continued systemic immunosuppression/systemic disease-modifying agents. 9. Evidence of clinically significant bleeding or active bleeding diathesis within 90 days before screening 10. History of malignancy or ongoing treatment for prior malignancy. 11. Inborn error of immunity and/or primary immunodeficiency. 12. Seropositive for HIV or HTLV (including any history of HIV or HTLV). 13. Active viral (any etiology, HBV, HCV) hepatitis are excluded. 14. 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. 15. Pregnant, breastfeeding, or planning to become pregnant while enrolled in this study or within 1 year after receiving study treatment, whichever is longer. 16. Unwilling or unsafe to proceed with CSF exams based on coagulopathy or anatomy or other considerations in the judgment of the study investigator. 17. Any contraindications to LP. 18. Participants not willing, able, or are unsafe to take MRI scans as per protocol.
