Tiziana Life Sciences, Ltd. (Nasdaq: TLSA) ("Tiziana"), a biotechnology company developing its lead candidate, intranasal foralumab, a fully human, anti-CD3 monoclonal antibody, announces that patient enrollment has been completed in its randomized, double-blind, placebo-controlled Phase 2a clinical trial evaluating intranasal foralumab in patients with non-active Secondary Progressive Multiple Sclerosis (na-SPMS). Topline data is expected in late Q3 of 2026, and will also to be presented at the 10th joint Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) and ECTRIMS meeting in Toronto, Canada in October 2026.

The trial (NCT06292923), known as INFORM-MS, is the first Phase 2 placebo-controlled study of intranasal foralumab, marking a significant milestone in the clinical development of this novel anti-CD3 monoclonal antibody for neurodegenerative and neuroinflammatory diseases. The multicenter study has enrolled 48 patients across multiple leading U.S. sites to receive one of two doses of intranasal foralumab or placebo over a 12-week treatment period, with assessments including PET imaging for microglial activation, MRI, clinical evaluations, and biomarkers. Following the completion of the blinded phase, all participants including those who initially received placebo will have the opportunity to receive intranasal foralumab during a six-month open label extension (OLE) phase. The OLE is designed to assess long term safety and sustained benefit of foralumab in the na-SPMS patient population.
