Rhea-AI Filing Summary

Tiziana Life Sciences Ltd (TLSA) announced a Memorandum of Understanding with King Abdullah International Medical Research Center, King Saud bin Abdulaziz University for Health Sciences, the Ministry of National Guard – Health Affairs, and the Foundation for Neurologic Diseases to collaborate on a clinical trial in multiple sclerosis.

The planned study will test Tiziana’s proprietary intranasal foralumab in combination with existing anti-CD20 therapy in relapsing-remitting multiple sclerosis patients who respond poorly to anti-CD20 alone, building on three prior clinical studies where intranasal foralumab reduced neuroinflammation. Tiziana highlights ongoing programs, including an expanded access program in non-active secondary progressive MS treating 14 patients with improvement or stability at six months, a Phase 2a randomized trial in na-SPMS, and additional Phase 2 trials in Alzheimer’s disease and multiple system atrophy, with blinded na-SPMS Phase 2 results expected in October.

Positive

  • None.

Negative

  • None.

Filing Explained

The September 17 Form 6-K records a signed MOU, but the parties only state that they intend to collaborate on the RRMS combination trial; the filing does not report that the trial has begun.

MOU announcement date September 17, 2026 Date Tiziana announced signing the MOU for the RRMS collaboration
Clinical studies of intranasal foralumab 3 studies Number of clinical studies where intranasal foralumab has been shown to reduce neuroinflammation
Expanded Access na-SPMS patients 14 patients Number of non-active secondary progressive MS patients dosed in the open-label Expanded Access Program
Expanded Access observation period 6 months Timeframe within which improvement or stability of disease was seen in all 14 na-SPMS patients
Trial phase in na-SPMS Phase 2a Randomized, double-blind, placebo-controlled, multicenter, dose-ranging trial of intranasal foralumab in na-SPMS
relapsing-remitting multiple sclerosis medical
"patients with relapsing-remitting multiple sclerosis (RRMS) who are responding poorly"
non-active secondary progressive multiple sclerosis medical
"patients with non-active secondary progressive multiple sclerosis (NCT06292923)"
Expanded Access (EA) Program regulatory
"dosed in an open-label intermediate sized Expanded Access (EA) Program"
neuroinflammation medical
"responding poorly to anti-CD20 therapy alone, which could be due to untreated neuroinflammation"
Neuroinflammation is the brain or spinal cord’s immune reaction to injury, infection, or abnormalities, where cells and molecules become active to protect or repair nervous tissue. It matters to investors because it underlies many neurological diseases and is a common target for drugs and diagnostic tools; positive or negative trial results, safety signals, or new therapies can change a company’s value much like a major repair plan or recall would affect a carmaker’s prospects.
immunomodulation medical
"breakthrough immunomodulation therapies with its lead development candidate, intranasal foralumab"
Immunomodulation is the intentional changing of the immune system’s activity—either ramping it up, calming it down, or redirecting it—to treat disease or prevent harmful reactions. Think of it like adjusting a thermostat for the body’s defenses: the goal is to achieve the right balance so patients heal without excessive inflammation or infection risk. For investors, immunomodulation matters because therapies in this area can address many diseases, carry regulatory and safety considerations, and often determine commercial potential and clinical risk.

Tiziana Life Sciences Announces Signing of MOU with King Abdullah International Medical Research Center

 

BOSTON, MA, September 17, 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 the signing of a Memorandum of Understanding (MOU) with the King Abdullah International Medical Research Center (KAIMRC) of King Saud bin Abdulaziz University for Health Sciences (KSAU-HS), Ministry of National Guard – Health Affairs, and the Foundation for Neurologic Diseases. Under the MOU, the parties intend to collaborate on a clinical trial evaluating a combination of Tiziana’s proprietary intranasal foralumab and existing anti-CD20 therapy in patients with relapsing-remitting multiple sclerosis (RRMS) who are responding poorly to anti-CD20 therapy alone, which could be due to untreated neuroinflammation. In three clinical studies to date, intranasal foralumab has been shown to reduce neuroinflammation.

 

The MOU was signed by Ivor Elrifi, CEO of Tiziana Life Sciences during an event on the main stage at the Riyadh Global Medical Biotechnology Summit (RGMBS) in Riyadh, Kingdom of Saudi Arabia, on Wednesday, September 16, 2026.

 

KAIMRC is a biomedical and clinical research center operating under the Ministry of National Guard – Health Affairs that pursues translational research and national research capability in alignment with Saudi Vision 2030 and the National Biotechnology Strategy. The Foundation for Neurologic Diseases is a research organization with recognized expertise in neuroimmunology and multiple sclerosis research.

 

“This MOU marks an important step in fostering international scientific collaboration in neuroimmunology and immunomodulation research,” said Ivor Elrifi, Chief Executive Officer of Tiziana Life Sciences. “We are pleased to partner with KAIMRC along with the Foundation for Neurologic Diseases to explore opportunities that align with our mission of advancing innovative therapies for neurodegenerative and neuroinflammatory diseases, including a clinical trial of foralumab in combination with anti-CD20 therapy for RRMS patients having suboptimal responses to anti-CD20 treatment alone. This represents an additional Multiple Sclerosis type beyond our ongoing non-active Secondary Progressive MS (na-SPMS) program, and does not change our efforts toward na-SPMS, where the Phase 2 trial remains blinded with results expected in October this year. Signing the agreement at RGMBS in Riyadh underscores the growing global interest in collaborative approaches to address these significant unmet medical needs.”

 

 

 

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]
