Foralumab

April 25, 2024 -- Tiziana Life Sciences, Ltd. (Nasdaq: TLSA) (“Tiziana” or the “Company”), a biotechnology company developing breakthrough immunomodulation therapies via novel routes of drug delivery, today announced for the first time, quantitative data showing improvement in White Matter Z-scores measured from PET images taken at 3 months in nasal foralumab treated patients with non-active secondary progressive multiple sclerosis (na-SPMS). White Matter Z-scores are a statistical measure used in neuroimaging studies to assess the integrity or abnormalities in structures of the brain. Tarun Singhal, MBBS, M.D., Director of PET Imaging Program in Neurologic Diseases at Brigham and Women’s Hospital, a founding member of Mass General Brigham Healthcare System, and Associate Professor of Neurology at Harvard Medical School, stated, “Last week at the American Academy of Neurology annual meeting, we presented, for the first time, quantitative [F18]PBR06-PET data showing the dampening of microglial activation, an indicator of brain inflammation, in patients with non-active Secondary Progressive Multiple Sclerosis (na-SPMS) receiving intranasal foralumab. These data came from the open-label intermediate-sized patient population Expanded Access (ISPPEA) program. We calculated White Matter Z-scores to measure the effect of intranasal foralumab on microglial activation at baseline and then after foralumab treatment for three months. We saw reductions of 28% to 48%, indicating improvement in 5 out of 6 patients, and a 36% median reduction in White Matter Z-scores compared to baseline (see Figure 1). A peer-reviewed journal has published our recent work with newer [F18]PBR06-PET quantitation approaches.”[1] The full publication in Clinical Nuclear Medicine can be found here: https://journals.lww.com/nuclearmed/fulltext/9900/glial_activity_load_on_pet_reveals_persistent.1077.aspx “I am grateful for Dr. Singhal’s work advancing our intranasal foralumab program and the insight his work provides into the foralumab’s effect on brain inflammation. We are seeing this additional, encouraging evidence of intranasal foralumab’s effect after reporting that it attenuated microglial activation in na-SPMS patients with progression independent of relapse activity (PIRA) at 3 months as evaluated by [F-18]PBR06-PET and was associated with clinical symptom improvement or stability. Based on these positive results, a double-blind, placebo-controlled, dose-ranging study (NCT06292923) of intranasal foralumab in na-SPMS with [F-18]PBR06-PET as a primary endpoint with clinical measures of EDSS (disability) and MFIS (fatigue) is currently underway. I welcome the publication of Dr. Singhal’s [F18]PBR06-PET research paper, highlighting these combined findings in Clinical Nuclear Medicine,” commented Gabriele Cerrone, Chairman, acting CEO and founder of Tiziana Life Sciences. Figure 1* *EA5 showed a worsening in their White Matter Z-Score at three months during a pseudo-exacerbation of the patient’s trigeminal neuralgia. Activated T cells play an essential role in the inflammatory process. Foralumab, the only fully human anti-CD3 monoclonal antibody (mAb), 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 demonstrated in patients with COVID and with multiple sclerosis, as well as in healthy normal subjects. The non-active SPMS intranasal foralumab Phase 2 trial began screening patients in November 2023. Immunomodulation by nasal anti-CD3 mAb represents a novel avenue for treating neuroinflammatory and neurodegenerative human diseases.[2],[3] Tiziana Life Sciences is a clinical-stage biopharmaceutical company developing breakthrough therapies using transformational drug delivery technologies to enable alternative routes of immunotherapy. Tiziana’s innovative nasal approach has the potential to provide an improvement in efficacy as well as safety and tolerability compared to intravenous (IV) delivery. Tiziana’s lead candidate, intranasal foralumab, the only fully human anti-CD3 mAb, has demonstrated a favorable safety profile and clinical response in patients in studies to date. Tiziana’s technology for alternative routes of immunotherapy has been patented with several applications pending and is expected to allow for broad pipeline applications.

NEW YORK, April 23, 2024 (GLOBE NEWSWIRE) -- Tiziana Life Sciences, Ltd. (Nasdaq: TLSA) (“Tiziana” or the “Company”), a biotechnology company developing breakthrough immunomodulation therapies via novel routes of drug delivery, today announced that the U.S. Food and Drug Administration (FDA) has allowed its intranasal foralumab non-active Secondary Progressive Multiple Sclerosis (na-SPMS) Expanded Access (EA) Program to expand from 10 patients to a total of 30 patients. To date, of the 10 participating patients, two patients have been dosed for more than one year and eight additional patients have been dosed for six months, all without serious side effects. All patients have either stabilized or improved on treatment with foralumab, and no patients have declined in key clinical measures. Additionally, 70% of these patients have seen a measurable improvement in fatigue. These data are the first to combine PET imaging with a novel ligand, immune-biomarkers, clinical measures and comprehensive safety data endpoints in patients receiving long-term intranasal foralumab. In November 2023 Tiziana initiated a Phase 2a trial in na-SPMS. Patients not eligible for the Phase 2a trial may now be considered for this expanded EA program. The September 2023 release of FDA guidance entitled “Guidance on Substantial and Confirmatory Evidence of Efficacy and Safety” addresses the use of EA programs to be considered as part of confirmatory evidence. As per FDA guidance, “Expanded access refers to the use of an investigational drug when the primary purpose is to diagnose, monitor, or treat a patient’s disease or condition rather than to obtain the kind of information about the drug that is generally derived from clinical trials.” Gabriele Cerrone, Chairman, acting CEO and founder of Tiziana Life Sciences commented, “Tiziana is glad to provide patients with na-SPMS who do not qualify to be enrolled on our Phase 2 trial (NCT06292923) the possibility to receive open-label treatment with our intranasal fully human anti-CD3 monoclonal-antibody, foralumab. As there are no FDA approved treatments for na-SPMS, an EA program gives these patients access to this novel drug.” “I am grateful to be allowed to dose 20 additional patients that do not meet the inclusion criteria for the ongoing intranasal foralumab Phase 2a, randomized, double-blind placebo-controlled, multicenter dose-ranging study multiple sclerosis trial potential access to this treatment,” stated Dr. Tanuja Chitnis, M.D., Professor of Neurology at Harvard Medical School and senior neurologist at Brigham and Women’s Hospital, a founding member of Mass General Brigham Healthcare System. “The EA program has allowed us to obtain important information about dosing, and drug use, including patient feedback which was critical for the design of the current Phase 2a trial.” About Foralumab Activated T cells play an important role in the inflammatory process.
