Tiziana Announces Reduction of Side Effects Commonly Seen with Discontinuation of GLP-1 Agonists with Nasal Anti-CD3
NEW YORK, Jan. 10, 2025 (GLOBE NEWSWIRE) -- 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 findings on the prolonged benefits of its nasal anti-CD3 monoclonal antibody in sustaining tissue homeostasis and mitigating the side effects associated with GLP-1 agonists discontinuation. This advancement offers a promising approach to overcoming the tolerability challenges and adverse effects commonly linked to prolonged GLP-1 drug use.
GLP-1 drugs, widely used for treating metabolic disorders, often face issues with long term tolerability, leading to side effects such as sarcopenia and bone density loss. These complications frequently result in the discontinuation of GLP-1 therapies, reversing their beneficial effects on tissue homeostasis. Tiziana’s nasal anti-CD3 therapy has been shown not only to enhance the positive effects of semaglutide, a GLP-1 agonist marketed by Novo Nordisk under the brand names Ozempic and Wegovy when administered together but now to potentially sustain these effects after a GLP-1’s discontinuation.
“One of the key challenges with GLP-1 drugs is their lack of tolerability over time, which can lead to adverse effects like muscle and bone loss,” said Dr. Howard 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. “Our research demonstrates that nasal anti-CD3 not only amplifies the beneficial effects of GLP-1 agonists but now also would potentially sustains these benefits even after discontinuation, providing a novel and non-toxic approach to maintaining tissue homeostasis and improving patient outcomes.”
Researcher, Selma Boulenouar PhD, elaborated on the findings: “Our data shows that even when on a high-fat diet, nasal anti-CD3 therapy sustains tissue homeostasis and mitigates inflammation in key organs, including adipose tissue, liver, kidneys, and brain. Importantly, the prolonged effects of nasal anti-CD3 are independent of dietary changes, making it a robust and versatile therapy for long-term metabolic health.”
The mechanism behind nasal anti-CD3’s efficacy lies in its ability to induce regulatory T cells, which dampen tissue inflammation and promote homeostasis. This discovery opens a new avenue for maintaining the positive effects of GLP-1 agonists, even in cases where discontinuation is necessary due to side effects or other factors.
“These findings are a pivotal step forward in the treatment of metabolic disorders and age-related diseases,” added Tiziana’s CEO, Ivor Elrifi. “Nasal anti-CD3 provides a unique opportunity to maximize and sustain the therapeutic benefits of GLP-1 drugs while mitigating their associated risks, ensuring long-term health and improved outcomes for patients.”
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]
