Behandling af deltagere med primær eller sekundær progressiv multipel sclerose (IMPACT-MS)
En fase 1/2a, åben-label, dosis-eskaleringsundersøgelse til vurdering af sikkerheden og foreløbig effekt af TRX319 hos personer med primær eller sekundær progressiv multipel sklerose
The goal of this clinical trial is to treat male and female participants with two types of Multiple Sclerosis (MS) called primary progressive or secondary progressive MS.
The main questions the trial aims to answer are the following:
- Is TRX319 safe when administered to patients with progressive forms of MS?
- At what dose does TRX319 work the best to treat participants with primary and or secondary progressive MS?
- Is pre-conditioning (with Bendamustine) needed to allow TRX319 to better treat participants with primary and/or secondary progressive MS?
Participants will be asked to be on study for up 1 year and may receive up to 3 total administrations of TRX319. While on study, participants will have blood tests and other assessments (MRI scans and lumbar punctures) done to understand the safety of TRX319 and how it may benefit their multiple sclerosis.

Beskrivelse
Inclusion Criteria:
- Clinical diagnosis of MS with evidence of PPMS or SPMS according to 2025 McDonald criteria.
- Expanded Disability Status Scale (EDSS) range ≥ 2.5 to ≤ 6.5.
- Evidence of clinical disability progression within 2 years prior to enrollment.
- Documented presence of CSF-restricted OCBs and/or elevated IgG index and/or κ free light chain.
- Males and females ≥ 18 and ≤ 65 years of age at time of consent.
- Evidence of adequate organ function
- Women of child bearing potential have a negative pregnancy test at screening.
- Contraceptive use by all participants while on study.
- Participants must be able to understand, consent, and be willing and able to complete all specified procedures and visits.
- Positive varicella zoster virus titer. Participants who test seronegative for varicella zoster virus IgG antibodies need to complete vaccination ≥ 4 weeks prior to TRX319 infusion.
- Participants must be willing to refrain from donating blood for 1 year after TRX319 infusion.
Exclusion Criteria:
- MS clinical stability on disease modifying therapy.
- Clinical relapse of MS in the 1 year prior to study entry.
- Diseases other than MS to explain the first demyelinating event, including aquaporin 4 IgG or myelin oligodendrocyte glycoprotein-IgG seropositivity.
- Prior treatment with CAR-T or gene therapy product directed at any target.
- Prior treatment with mitoxantrone, cladribine (or other chemotherapies), or alemtuzumab within 2 years prior to TRX319 dose.
- Prior treatment with CD20-depleting antibodies within 3 months and prior treatment with Bruton's tyrosine kinase inhibitor (BTKi) and sphingosine 1 phosphate (S1P) modulators within 1 month of TRX319 dose.
- Plan to or have received live, attenuated vaccines less than 4 weeks (28 days) prior to TRX319 infusion, and other vaccines less than 2 weeks (14 days) prior to TRX319 infusion.
- Serologic status reflecting active hepatitis B or C infection.
- Positive serology for human immunodeficiency virus (HIV).
- History of progressive multifocal leukoencephalopathy.
