Researchers are evaluating the efficacy and safety of KarXT in adult Japanese participants who are acutely psychotic with schizophrenia. This Phase 3 study focuses on adults aged 18 to 65 years who meet specific criteria based on psychiatric evaluations and symptom severity scores. The trial aims to understand how KarXT affects schizophrenia symptoms compared to a placebo over a 5-week period, followed by a longer open-label extension. Participants are randomly assigned to receive either KarXT or a placebo during a 5-week double-blind treatment phase. Following this, they may enter a 52-week open-label extension where all participants receive KarXT. The study includes regular dosing on specified days, with careful monitoring throughout both phases. During their participation, individuals undergo assessments of symptom changes using scales like the Positive and Negative Syndrome Scale PANSS and Clinical Global Impressions-Severity CGI-S. Safety is closely monitored through reports of adverse events, physical exams, laboratory tests, heart rate and blood pressure measurements, and other evaluations. The total study duration can last over a year, allowing for detailed observation of treatment effects and safety over time.

Researchers are evaluating the effectiveness and safety of the drug SEP-363856 in adults experiencing acute psychotic episodes related to schizophrenia. This Phase 3 clinical trial uses a randomized, double-blind, placebo-controlled design to compare SEP-363856 against placebo in a parallel-group multicenter setting. The study focuses on participants aged 18 to 65 who are experiencing a recent worsening of schizophrenia symptoms. Participants are assigned to one of three groups receiving either a placebo, 75 mgday of SEP-363856, or 100 mgday of SEP-363856 tablets. The study treatment is given daily, and the trial lasts for six weeks. During this time, efficacy and safety data are collected to assess the impact of SEP-363856 on schizophrenia symptoms. Throughout the study, participants undergo regular assessments including the Positive and Negative Syndrome Scale PANSS and the Clinical Global Impression-Severity CGI-S scale to measure symptom changes from baseline to week 6. Safety is monitored as part of the trial. Participants are followed until the end of the six-week treatment period, with all study visits and procedures conducted during this timeframe.

Researchers are evaluating the efficacy and safety of tozorakimab delivered under the skin in adults with uncontrolled asthma who are already using medium-to-high doses of inhaled corticosteroids. This phase IIb, double-blind, placebo-controlled study aims to find the optimal dosing range of tozorakimab in this population. The study is sponsored by AstraZeneca and uses a randomized, parallel design to compare different doses and placebo. Participants will receive subcutaneous injections of either tozorakimab at one of two dose levels or a placebo. The study arms include dosing with tozorakimab Dose 1, tozorakimab Dose 2, or placebo, administered under the skin. The treatment period lasts from 26 to 52 weeks, during which participants will be monitored for their asthma symptoms and lung function. Throughout the study, participants will undergo assessments including lung function tests such as forced expiratory volume in 1 second FEV1, asthma control questionnaires ACQ-6, quality of life questionnaires AQLQ12, and measurements of asthma exacerbations. Blood samples will be collected to measure drug levels and immune response. Safety and adherence will be closely monitored, and the primary outcome is the annualized rate of severe asthma exacerbations over the treatment period.
