Tiziana Life Sciences Announces Positive Results from Ozempic and Nasal Anti-CD3 Combination Study

NEW YORK, October 30, 2024 – 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 positive results demonstrating the anti-inflammatory potential of our anti-CD3 antibody (foralumab) in combination with semaglutide, a GLP-1 agonist marketed by Novo Nordisk (NYSE: NVO) under the brand names Ozempic and Wegovy. The data show that the combination of nasal anti-CD3 plus semaglutide improves liver homeostasis and reduces inflammation in models of diet-induced obesity (DIO), providing a potential novel approach to combat obesity-related inflammation, and liver inflammation and dysfunction.

Key Highlights:

● Nasal anti-CD3 in combination with semaglutide demonstrates synergistic effects in promoting liver homeostasis in preclinical models of diet-induced obesity.

● The combination significantly reduces inflammation markers, a key factor in obesity-related metabolic disorders.

In Figure 1, the far-right column shows the explanted liver and histology of that liver at two magnifications for a mouse fed a low-fat chow “normal” diet (“lean mouse”). The dark and smaller liver on the right is a typical healthy liver from a lean mouse. All the mice under the gray bar in the figure were fed a high fat chow (“HFD”) resulting in diet induced obesity. As the columns outlined by red boxes demonstrate, administration of the combination of nasal anti-CD3 and semaglutide had livers that looked more like the liver from the lean mouse. The HFD mice given low dose or high dose semaglutide alone had enlarged fatty livers that were more similar to the HFD control.

In humans, nasal foralumab modulates immune responses by inducing regulatory-type T cells. semaglutide is an effective therapy for obesity and Type 2 diabetes, known for its role in enhancing insulin sensitivity and reducing body weight.

This study, conducted by Dr Howard Weiner and Selma Boulenouar PhD, and a research team at Brigham and Women’s Hospital, Boston, Massachusetts, demonstrates that nasal anti-CD3 in combination with Semaglutide, helps restore liver homeostasis in diet induced obesity models where liver dysfunction and inflammation are prominent. The combination therapy led to marked reductions in pro-inflammatory cytokines and significant improvements in liver markers associated with metabolic regulation. This suggests a dual benefit in both managing obesity and preventing its associated inflammation-related complications.

“We are excited by the potential of this novel combination. Nasal foralumab’s ability to modulate immune response in humans has always been promising. Now, combining anti-CD3 with semaglutide, resulted in additional benefit on liver homeostasis and reduced inflammation in this mouse model. This could pave the way for an entirely new approach in treating obesity-related metabolic disorders,” said 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, a founding member of Mass General Brigham healthcare system.

Selma Boulenouar PhD, a leading researcher at Brigham and Women’s Hospital, who co-led the study, commented: “The results of this study are very encouraging. Chronic inflammation is a hallmark of obesity and liver diseases. The combination of anti-CD3 with Semaglutide appears to mitigate this inflammatory response and restore normal liver function. These findings underscore the potential for combination therapies in addressing complex metabolic and inflammatory conditions.”

Obesity is a growing global health concern, with associated metabolic disorders including insulin resistance, NAFLD, and chronic inflammation contributing to increased morbidity and healthcare costs. The combination of nasal Foralumab for modulating the immune system and semaglutide for weight management offers a novel therapeutic combination that addresses both the metabolic and inflammatory aspects of obesity.

Ivor Elrifi, CEO of Tiziana Life Sciences, commented, “We are excited by these findings, which demonstrate nasal Foralumab’s potential to significantly enhance the therapeutic effects of semaglutide. This combination may present a breakthrough approach to treating not only obesity but also the downstream metabolic complications that are often hard to manage with current therapies. We would like to thank Howard and Selma and the BWH team for their thorough study that has taken many months to complete. We look forward to the full publication of these findings in a peer-reviewed journal.”

Tiziana plans to advance these promising preclinical findings into further clinical development, with the goal of initiating in-human clinical trials in the future. This effort is aligned with the Company’s commitment to pioneering innovative solutions for inflammatory and metabolic diseases, leveraging the immunomodulatory properties of Foralumab.

The study at Brigham and Women’s Hospital is part of Tiziana’s broader development program for Foralumab, which includes other inflammatory and autoimmune indications. The Company remains dedicated to advancing scientific innovations to address unmet medical needs across diverse therapeutic areas.

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, 10 patients with Non-Active Secondary Progressive Multiple Sclerosis (na-SPMS) have been dosed in an open-label intermediate sized Expanded Access (EA) Program with either an improvement or stability of disease seen within 6 months in all patients. The FDA has recently allowed an additional 20 patients to be enrolled in this EA program. 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).

Activated T cells play an important role in the inflammatory process. Foralumab, the only fully human anti-CD3 monoclonal antibody (mAb) currently in clinical development, binds to the T cell receptor and dampens inflammation by modulating T cell function, thereby suppressing effector features in multiple immune cell subsets. This effect has been observed in patients with COVID and with multiple sclerosis, as well as in healthy normal subjects. The non-active SPMS intranasal foralumab Phase 2 trial (NCT06292923) began screening patients in November of 2023. Immunomodulation by nasal anti-CD3 mAb represents a novel avenue for treatment of neuroinflammatory and neurodegenerative human diseases.^[1],[2]
