TLSA Tiziana Life Sciences Ltd

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 a product development services agreement with Renaissance Lakewood LLC (“Renaissance”), a leading Contract Development and Manufacturing Organization (CDMO) focused on nasal drug delivery. This collaboration aims to optimize the current formulation and develop a comprehensive plan for the scale-up of foralumab in a nasal device. Intranasal foralumab is currently under development for treating neurodegenerative and inflammatory diseases or conditions.

Under this agreement, Renaissance will use its extensive expertise in pharmaceutical-nasal product development and manufacturing to support the production of intranasal foralumab, ensuring compliance with the highest quality and regulatory requirements. This collaboration is a critical step in Tiziana's strategy to expedite clinical development and potential commercialization of intranasal foralumab.

Intranasal foralumab offers a novel therapeutic approach by modulating the immune system to reduce neuroinflammation, a key factor in the progression of diseases such as Alzheimer's disease and multiple sclerosis. Recent studies have demonstrated its potential to activate regulatory T cells that cross the blood-brain barrier, dampening microglial activation and providing therapeutic benefits to patients.

Ivor Elrifi, CEO of Tiziana Life Sciences, commented, “Partnering with Renaissance is a significant milestone in our mission to bring intranasal foralumab to patients in need. Their proven track record in pharmaceutical manufacturing will be invaluable as we advance our clinical programs and prepare for potential market entry.”

This collaboration aligns with Tiziana's commitment to addressing unmet medical needs through innovative therapies. It represents a pivotal advancement in the Company's efforts to deliver effective treatments for debilitating neurodegenerative and inflammatory conditions.

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 Phase 2a, a 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]
