Researchers are assessing the safety and effects of Ritlecitinib, a study medicine, for treating hidradenitis suppurativa (HS), a condition causing long-lasting, painful red skin lumps. This phase 2 study focuses on adults with moderate to severe HS who have not responded well to or cannot tolerate antibiotics. The goal is to compare experiences and outcomes between those receiving Ritlecitinib and those receiving a placebo. Participants will be randomly assigned to take either Ritlecitinib or a placebo pill once daily at home. The treatment involves an initial loading dose of Ritlecitinib for 8 weeks, followed by an 8-week maintenance dose, totaling 16 weeks of treatment. The placebo group will receive a matching pill with no active medicine. Over approximately 24 weeks, including screening and follow-up, participants will attend around 10 clinic visits for health evaluations, including physical exams, blood and urine tests, vital signs, chest X-rays, ECGs, hearing tests, and questionnaires. They will also track their medication intake and HS symptoms daily using an electronic diary on a mobile phone. The study will measure how many patients achieve at least a 50% improvement in HS symptoms by week 16 to evaluate treatment response and safety.

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 evaluating the safety and effectiveness of adding KarXT (Xanomeline/Trospium Chloride) to standard treatment for mania in adults with Bipolar-I Disorder. This Phase 3, randomized, double-blind study focuses on individuals experiencing acute manic episodes, with or without mixed features, who are already taking lithium, valproate, or lamotrigine. The study aims to measure changes in mania symptoms using the Young Mania Rating Scale at Week 5. Participants will be randomly assigned to receive either KarXT or a placebo alongside their stable dose of lithium, valproate, or lamotrigine. The doses of these medications are specified and given on set days during the study. Only those with stable mood stabilizer doses for at least two weeks prior to screening, and valproate treatment for at least seven months, are eligible. The treatment period lasts for 5 weeks. During the study, participants will be closely monitored through psychiatric evaluations and clinical assessments. Researchers will assess mania severity, safety, and any side effects. The main outcome is the change from baseline in the Young Mania Rating Scale score at Week 5. Participants’ physical health, including liver function and risk of urinary or gastrointestinal issues, will also be monitored to ensure safety throughout the trial.

Researchers are evaluating the long-term safety and tolerability of adjunctive KarXT, a combination of xanomeline and trospium chloride, in adults aged 18 to 65 with schizophrenia who did not have sufficient symptom control with their current antipsychotic medications. This Phase 3, open-label extension study involves participants who previously completed the treatment period of the ARISE study (KAR-012). The goal is to monitor how well patients tolerate KarXT over an extended period while assessing related safety concerns. Participants receive fixed doses of KarXT capsules twice daily, with doses ranging from 50 mg/20 mg up to 125 mg/30 mg. The study lasts for 52 weeks as an outpatient program. This open-label extension allows researchers to observe the effects and safety of KarXT when added to stable antipsychotic treatment under real-world conditions. During the study, researchers closely monitor participants for any treatment-emergent adverse events from the initial dose through a safety follow-up visit at 54 weeks or early termination. Participants will undergo regular assessments, including clinical evaluations and reports from reliable caregivers who assist with study activities. The study ensures participants maintain stable living situations and continue their background antipsychotic medications throughout the study period.

Researchers are assessing the effectiveness of NBI-1117568 compared to a placebo in preventing relapse of schizophrenia symptoms in adults. This Phase 3 study focuses on individuals who have shown a stable response after initial open-label treatment with NBI-1117568. The study aims to determine how well NBI-1117568 delays the return of symptoms in this population. Participants receive either oral capsules of NBI-1117568 or a matching placebo in a double-blind, randomized withdrawal design. The treatment phase follows the open-label period where all participants initially receive NBI-1117568. This setup allows comparison of relapse times between those continuing the drug and those switched to placebo. Throughout the study, researchers monitor the time from randomization to symptom relapse for up to about 30 weeks. Participants undergo psychiatric evaluations and safety assessments to track tolerability and any adverse effects. The study includes adults aged 18 to 65 with stable schizophrenia who have responded to prior antipsychotic therapy, and it aims to provide detailed information on the safety and efficacy of NBI-1117568 over the treatment period.

Researchers are evaluating the long-term safety and tolerability of the drug NBI-1117568 in adults diagnosed with schizophrenia. This phase 3, global, multicenter, open-label study focuses on adults aged 18 to 65 years with a primary diagnosis of schizophrenia. The study aims to better understand how this medication performs over an extended period in this patient group. Participants will receive NBI-1117568 according to a specified dosing schedule. The treatment is administered openly, meaning both researchers and participants know the medication being given. No comparator or placebo group is mentioned, and the study primarily monitors the safety and side effects related to the drug over time. Throughout the study, participants will be closely monitored for any treatment-emergent adverse events for up to 36 months. Researchers will assess safety through regular evaluations and check participants' adherence to the protocol. The study includes careful screening and ongoing observation to ensure participant well-being and the collection of long-term safety data.
