What happened

The ClinicalTrials.gov record NCT07826689 describes a planned two-part study: single doses in healthy adults, followed by monthly doses in adults with relapsing MS and chronic optic neuropathy. The 17 September 2026 posting date and study details were available through a secondary mirror attributing them to ClinicalTrials.gov; they could not be independently checked against the primary record.

What this means for people with MS

This is a research plan, not a result. Current recruitment and whether the study has started remain unconfirmed.

What kind of evidence exists?
Trial description reported through a secondary registry mirror; no results available
How reliable is this source?
The primary record is linked but was not independently retrievable; the date and description were checked only in a secondary mirror.

Kamuvudine-9 study reports findings in a mouse model of MS

The paper reports that K-9 limited and reversed some vision and movement problems in mice with experimental autoimmune encephalomyelitis, an MS model, and preserved nerve cells and myelin. A separate insurance-data analysis in the paper concerns other NRTI medicines, not K-9.

What this means for people with MS

The findings are from animals and do not show that K-9 benefits people with MS. Associations involving other NRTIs are not clinical evidence for K-9.

Results from people

MSC-NP study finds CSF biomarker changes in two progressive MS cohorts

Research group: Tisch Multiple Sclerosis Research Center of New York · United States

A published analysis examined cerebrospinal-fluid samples from two groups of people with secondary or primary progressive MS: 50 participants in a Phase 2 study and 43 in an expanded-access programme. After repeated intrathecal autologous MSC-NP treatment, CCL2, MMP9, SCF and CHIT1 changed in cerebrospinal fluid. NfL and GFAP did not show the same pattern of change.

What this means for people with MS

These findings may help measure biological response and guide future study design. They do not show remyelination, improvement in symptoms or disability, or an established benefit to patients.

Laboratory and animal research

Blocking fibronectin restored remyelination in experimental models

A PNAS study found that a protein called fibronectin can build up in areas where myelin has been lost. This may trap immature cells that could otherwise become myelin-making cells. Blocking fibronectin improved myelin repair and symptoms in two animal models.

What this means for people with MS

This points to an interesting new biological target, but the approach has not been tested in people and there is no approved medicine based on it.
