Tiziana Life Sciences Announces Acquisitionof Shares by Executive Chairman

BOSTON, MA, December 19, 2025 – 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 announces that it has been notified that Panetta Partners Limited, an entity in which Gabriele Cerrone, the Executive Chairman has a beneficial interest has purchased 97,687 common shares, bringing his total holding to 43,374,830 common shares, which is 36.08% of issued share capital.

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).

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]^
