− Pre-Specified Interim Analysis Shows Positive Safety and Efficacy Results; Mezagitamab Safe and Well Tolerated − Takeda Intends to Initiate a Global Phase 3 Trial of Mezagitamab in Patients with Primary Immune Thrombocytopenia in Fiscal Year 2024 − Late-Stage Pipeline Continues to Gain Momentum With Five New Molecular Entities in Phase 3 Development in Fiscal Year 2024 OSAKA, Japan & CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Takeda (TSE:4502/NYSE:TAK) today announced positive topline results from a Phase 2, randomized, double-blind, placebo-controlled study evaluating the safety, tolerability and efficacy of mezagitamab (TAK-079) in patients with persistent or chronic primary immune thrombocytopenia (ITP). Mezagitamab is a fully human immunoglobulin IgG1 monoclonal antibody (mAb) with high affinity for CD38 expressing cells (including plasmablasts, plasma cells, natural killer cells) resulting in their depletion. The TAK-079-1004 trial (NCT04278924) evaluated three different doses of subcutaneous mezagitamab vs placebo, given once weekly for eight weeks in patients with chronic (more than one year in duration) or persistent (3-12 months in duration) primary ITP. An interim analysis of the ongoing Phase 2 study demonstrated positive safety and efficacy results. Mezagitamab has been generally safe and well tolerated across all three cohorts. All mezagitamab doses tested demonstrated a higher platelet response rate than placebo. The increases in platelet count were dose-dependent with the greatest platelet response observed at the highest dose tested. Platelet response in mezagitamab treated patients occurred rapidly and was maintained post-therapy. Based on these positive results, and following consultation with global health authorities, Takeda plans to initiate a global Phase 3 trial of mezagitamab in ITP in fiscal year 2024. When mezagitamab advances to Phase 3 in ITP Takeda will have five new molecular entities in Phase 3 development in fiscal year 2024 including TAK-279 for the treatment of psoriasis and psoriatic arthritis, TAK-861 for the treatment of narcolepsy type 1, soticlestat for the treatment of Lennox-Gastaut syndrome and Dravet syndrome, and fazirsiran for the treatment of α1-antitrypsin associated liver disease. ITP is a rare, IgG mediated autoimmune disease caused, in part, by the development of autoantibodies to platelets (and/or megakaryocytes), which are blood cells responsible for preventing or stopping bleeding. ITP is characterized by the accelerated destruction of platelets (with or without impaired production), resulting in a decreased platelet count and an increased risk of bleeding, which can be debilitating (including fatigue and impaired quality of life), and in severe cases may be life-threatening. The precedent for approval of new drugs in this indication requires that platelet counts be maintained at 50,000/uL or more for a sustained period. Approximately 20 percent of patients with ITP do not achieve a platelet count above 50,000/uL following treatment with available first- and second-line therapies creating significant patient burden and unmet need for a disease modifying treatment that is also tolerable.1,2 “These Phase 2 results demonstrate mezagitamab’s compelling disease modifying mechanism of action, which has the potential to achieve disease remission for people with ITP. There remains considerable unmet need among ITP patients who may not respond or have inadequate response to prior treatment. In addition, some patients who do respond to available therapies struggle to manage side effects or relapse despite treatment,” said Chinwe Ukomadu, Head of the Gastrointestinal & Inflammation Therapeutic Area Unit at Takeda. “We look forward to initiating the Phase 3 trial and presenting these data at an upcoming scientific congress.” Therapy with mezagitamab is designed to deliver rapid and sustained improvement in platelet response and generally rapidly restores platelet counts to functional levels. Mezagitamab previously received Orphan Drug Designation for the treatment of ITP from the U.S. Food and Drug Administration and the program recently received Fast Track Designation. Results from the Phase 2 trial have no impact on the full year consolidated reported forecast for the fiscal year ending March 31, 2024 (Fiscal Year 2023).

The prevalence of ADHD among prison populations is believed to be around ten times that of the general population. Amphetimine-based drugs used to treat ADHD may cut fatality risk, suggests study published in JAMA, one of the world's most widely read medical journals Medicines used to treat children and adults with attention deficit/hyperactivity disorder (ADHD) reduce the higher-than-average risk for premature death, suggests a study in the world’s most widely distributed medical journal. Researchers in Sweden tracked 148,578 children and adults with ADHD. Within three months of being diagnosed, about 57% had started on medications. Within two years, 632 patients had died, the researchers reported. Overall, among every 10,000 individuals, mortality rates were 39.1% in the medication group compared with 48.1% in those not receiving treatment. The findings were reported in JAMA , the world’s most widely circulated  international peer-reviewed general medical journal. More than half of the deaths were due to unnatural causes, such as accidental injuries, accidental poisoning, and suicide. After accounting for other risk factors, use of medication was associated with 21% lower odds of death from any cause, and 25% lower odds of death from unnatural causes, for males in particular, the researchers found. The short-term study was not a randomised trial, so it is unclear whether the use of medication explains the results and, if it does, whether the effect is seen over time. Also unclear, according to an editorial published with the study, is whether ADHD treatment reduces the risk of premature death directly by reducing impulsive behaviours, or indirectly by alleviating core symptoms of the disease. “Future research should investigate the potential relationship between ADHD symptom severity and mortality outcomes for those receiving medication treatment,” the editorial said. ADHD pharmas include Teva, Janssen & Noven ADHD affects 5.9% of young people and 2.5% of adults worldwide, according to the 2021 World Federation of ADHD International. The prevalence of ADHD among prison populations is believed to be around ten times that of the general population. An estimated 25% of adults in prison have ADHD, compared to 2.5% of adults in the general population ( Young & Cocallis, 2021 ). ADHD medicines are amphetamine-based. Amphetamine is a central nervous system stimulant, and is also used in the treatment of narcolepsy and obesity. It was discovered as a chemical in 1887 by Lazăr Edeleanu, and used as a drug in the late 1920s. The first amphetamine pharmaceutical was Benzedrine. Modern amphetamine-based medicines include Adderall ( Teva Pharmaceutical ), Concerta ( Janssen ), Daytrana ( Noven ), Dexedrine ( Cardinal Health ) and Dyanavel XR ( Tris Pharma ). Amphetamine is a tightly controlled pharmaceutical, due to the health risks associated with recreational use. About JAMA JAMA , first published in 1883.
