[{"type":"text","content":"BOSTON, Feb. 25, 2026 (GLOBE NEWSWIRE) -- Tiziana Life Sciences, Ltd. (Nasdaq: TLSA) (“Tiziana”), a biotechnology company developing its lead candidate, intranasal foralumab, a fully human, anti-CD3 monoclonal antibody, announces positive new biomarker data from a late-breaking poster titled “Nasal foralumab downregulates CSF inflammation and upregulates CSF neuroprotective proteomic pathways which correlate with [F-18]PBR06-PET imaging in na-SPMS with PIRA,” which was presented by investigators from Brigham and Women’s Hospital, Boston, MA. In multiple sclerosis (MS), an autoimmune disease involving inflammation, demyelination, and neurodegeneration in the CNS, Cerebrospinal fluid (CSF) plays a crucial role in diagnosis, understanding disease mechanisms, and monitoring progression, especially in progressive forms like non-active secondary progressive MS (na-SPMS) with progression independent of relapse activity (PIRA). CSF analysis, typically obtained via lumbar puncture, provides direct insight into CNS-specific processes because it reflects the local environment around the brain and spinal cord, unlike blood which can be influenced by systemic factors. The late-breaking poster reports results from 10 patients with non-active secondary progressive multiple sclerosis (na-SPMS) and progression independent of relapse activity (PIRA) treated with nasal foralumab in an open-label expanded-access program. Patients underwent 14 paired evaluations of [F-18]PBR06-PET scans (measuring microglial activation via m-GALP z-scores) and untargeted data-independent acquisition CSF proteomics at baseline and during up to 6 months of treatment. Key findings include: Nasal foralumab treatment significantly reduced voxel-wise average [F-18]PBR06-PET m-GALP z-scores in white matter and global brain regions (p","length":2264,"tagName":"div"}]
