Researchers are evaluating the long-term safety and tolerability of KarXT in treating mania or mania with mixed features in adults with Bipolar-I disorder. This phase 3, open-label extension study aims to better understand how KarXT performs over an extended period in this population. The study includes participants who either completed previous double-blind placebo-controlled studies or are newly diagnosed with Bipolar-I disorder experiencing manic symptoms. Participants receive KarXT at specified doses on certain days, with some also taking therapeutic doses of Lithium, Valproate, or Lamotrigine as part of their treatment. The study does not mention a placebo group during this extension, focusing instead on monitoring the long-term effects of KarXT alone or in combination with these established therapies. During the study, participants are monitored for adverse events up to week 54 to assess safety. Evaluations include psychiatric assessments using scales such as the Young Mania Rating Scale and CGI-BP score at screening and baseline. Researchers will track treatment-emergent adverse events and overall tolerability throughout the study duration, which lasts up to 54 weeks for each participant.

Researchers are investigating the safety and effectiveness of KarXT in treating manic episodes in adults with Bipolar-I Disorder. This Phase 3 study focuses on individuals experiencing acute mania or mania with mixed features who require hospitalization. The study aims to compare KarXT with a placebo to see how well it reduces manic symptoms during a three-week inpatient period. Participants will be randomly assigned to receive either KarXT or a placebo at specified doses during the inpatient treatment phase. The study is double-blind, so neither the participants nor the researchers know who receives which treatment. The total study duration, including screening, treatment, and safety follow-up, will not exceed seven weeks. During the study, participants will be closely monitored through psychiatric evaluations and rating scales, including the Young Mania Rating Scale (YMRS) to measure changes in mania symptoms by week 3. Other assessments include the Clinical Global Impressions-Bipolar scale and safety evaluations. Researchers will track adherence, symptoms, and any side effects throughout the study period.

Researchers are evaluating the effectiveness and safety of KarXT in Japanese adults aged 18 to 65 who are experiencing acute psychotic episodes due to schizophrenia. The study focuses on adults diagnosed with schizophrenia according to the Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (DSM-5) and confirmed by a psychiatric interview. Participants must have a specific range of symptom severity measured by the Positive and Negative Syndrome Scale (PANSS) and Clinical Global Impression-Severity (CGI-S) scale. Participants are randomly assigned to receive either KarXT or a placebo during a 5-week double-blind phase where neither the participants nor the researchers know which treatment is given. After this, there is a 52-week open-label extension where all participants receive KarXT. The doses are specified and administered on set days throughout the study. Throughout the study, researchers monitor changes in schizophrenia symptoms using the PANSS score at week 5 and track any treatment-emergent adverse events up to week 52 during the open-label extension. The study involves regular assessments to ensure safety and effectiveness over both the short and long term, with total participation lasting up to 57 weeks.

Researchers are evaluating the safety and effectiveness of rituximab (genetical recombination) given through an intravenous infusion for people with idiopathic membranous nephropathy who also have nephrotic syndrome. This phase 3 study aims to confirm how well rituximab works and how safe it is compared to a placebo. The study focuses on patients aged 15 years and older who meet specific clinical criteria related to their kidney condition and protein levels. Participants will receive either rituximab or a placebo through intravenous infusions given every two weeks for two doses during the double-blind phase. If patients do not show sufficient improvement by week 26, they may enter an open-label phase where they can receive rituximab again if deemed necessary by the investigator. The treatment dosing in the open-label phase is the same as in the initial phase, with two doses of 1,000 mg rituximab given every two weeks. During the study, participants will be monitored to measure the percentage of patients achieving predefined remission criteria by week 26. Assessments will likely include lab tests for protein levels and albumin in the blood, kidney function, and safety evaluations. The study involves informed consent, screening for eligibility, and ongoing monitoring to evaluate treatment response and safety throughout the study period.

Researchers are evaluating the effectiveness, safety, and tolerability of subcutaneous lunsekimig compared to a placebo in adults aged 40 to 80 years with inadequately controlled chronic obstructive pulmonary disease (COPD) characterized by an eosinophilic phenotype. This Phase 2b/Phase 3, parallel, 3-arm study focuses on participants who have a history of COPD with an eosinophilic profile and have not achieved control with current treatments. Eligible participants will receive either lunsekimig or a matching placebo through subcutaneous injections over a randomized treatment period of approximately 48 weeks. The study involves three periods: an initial screening period lasting up to 4 weeks, followed by the 48-week treatment period, and finally an 8-week follow-up period. The total study duration may last up to 60 weeks. During the study, participants will be regularly assessed for the annualized rate of moderate-to-severe COPD exacerbations from baseline up to 48 weeks. Researchers will monitor safety, tolerability, and treatment effects through various evaluations throughout the treatment and follow-up periods. Participant involvement includes completing assessments and receiving scheduled injections as part of the study protocol.
