The study’s endpoints include neuroinflammation imaging, cognitive function, and fluid biomarkers related to amyloid and tau pathology.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Filing Summary
Tiziana Life Sciences Ltd (TLSA) announced that the last patient has begun dosing in its Phase 2 randomized, placebo-controlled trial of intranasal foralumab for early/mild Alzheimer’s disease, completing enrollment and starting dosing for all participants. The study evaluates foralumab alone and alongside FDA-approved lecanemab or donanemab; topline data are anticipated in Q1 2027.
The study assesses safety and tolerability and potential efficacy. Separately, Tiziana reports that 14 patients with non-active secondary progressive multiple sclerosis in an open-label expanded-access program had either improvement or stability of disease within 6 months.

Tiziana Doses Last Patient in Phase 2 Trial of Intranasal Foralumab for Mild Alzheimer’s Disease
BOSTON, MA, October 16, 2026 – Tiziana Life Sciences, Ltd. (Nasdaq: TLSA) (“Tiziana” or the “Company”), a biotechnology company developing breakthrough immunomodulation therapies with its lead development candidate, intranasal foralumab, a fully human, anti-CD3 monoclonal antibody, today announced that the last patient has begun dosing in its Phase 2 randomized, placebo-controlled clinical trial evaluating intranasal foralumab in patients with early/mild Alzheimer’s disease (AD). Topline data are anticipated to be announced in Q1 2027.
This milestone completes enrollment and initiates dosing for all participants in the study, which is assessing the safety, tolerability, and potential efficacy of intranasal foralumab both as monotherapy and in combination with FDA-approved anti-amyloid therapies lecanemab (Leqembi®) or donanemab. The trial builds on evidence of persistent neuroinflammation (microglial activation) in Alzheimer’s patients, including those treated with anti-amyloid agents, as measured by TSPO-PET imaging. Key endpoints include changes in neuroinflammation via TSPO-PET imaging, cognitive function, and fluid biomarkers related to amyloid and tau pathology.
“Dosing the last patient in this important Phase 2 trial is a significant achievement for our team, clinical sites, and the patients participating in the study.” commented Ivor Elrifi, Chief Executive Officer of Tiziana Life Sciences. “We look forward to generating data that could help establish immunomodulation as a complementary pillar in the treatment of early Alzheimer’s disease.”
“Completing dosing initiation for the final patient marks an important step in testing whether inducing regulatory T cells with intranasal foralumab can calm activated microglia and potentially slow disease progression in mild Alzheimer’s.” commented Dr. Howard L. Weiner, Chairman of Tiziana’s Scientific Advisory Board and Co-Director of the Ann Romney Center for Neurologic Diseases at Brigham and Women’s Hospital. “Our prior work, including TSPO-PET findings in multiple sclerosis and the moderate Alzheimer’s expanded-access experience, supports the biological rationale that addressing chronic brain inflammation alone or alongside anti-amyloid therapy, may offer meaningful benefit. We look forward to seeing the results from this placebo-controlled trial.”
About the Phase 2 Alzheimer’s Disease Trial
The Phase 2 study is a randomized, placebo-controlled trial in patients with early/mild Alzheimer’s disease. It evaluates intranasal foralumab as monotherapy and in combination with lecanemab or donanemab. Primary focus areas include safety/tolerability, reduction in microglial activation measured by TSPO-PET, cognitive outcomes, and changes in amyloid and tau biomarkers.
About Foralumab
Foralumab, a fully human anti-CD3 monoclonal antibody, is a biological drug candidate that has been shown to stimulate T regulatory cells when dosed intranasally. At present, 14 patients with Non-Active Secondary Progressive Multiple Sclerosis (na-SPMS) have been dosed in an open-label intermediate sized Expanded Access (EA) Program (NCT06802328) with either an improvement or stability of disease seen within 6 months in all patients. In addition, intranasal foralumab is currently being studied in a Phase 2a, randomized, double-blind, placebo-controlled, multicenter, dose-ranging trial in patients with non-active secondary progressive multiple sclerosis (NCT06292923), as well as additional Phase 2 trials in AD and MSA.
Intranasal foralumab is the only fully human anti-CD3 monoclonal antibody (mAb) currently in clinical development. Immunomodulation by intranasal foralumab represents a novel avenue for the treatment of neuroinflammatory and neurodegenerative human diseases.1,2
