Researchers are evaluating the effectiveness and safety of Xeomin injections in preventing chronic migraine. This Phase 3 clinical trial compares Xeomin to placebo injections given into muscles of the head and neck. Participants have chronic migraine diagnosed for at least 12 months and meet specific headache and migraine day criteria. The study aims to measure changes in monthly migraine days over time with Xeomin treatment. Participants will receive four treatments spaced about 12 weeks apart over a total study duration of 52 to 55 weeks. The treatments involve injections of either Xeomin or placebo solution prepared with sodium chloride. Visits occur approximately every 4 weeks, totaling 14 visits: the first, last, and four treatment visits are on-site, while the other eight visits are remote via phone or video call. During the study, participants will keep headache diaries to track migraine and headache days. Researchers will focus on the change in monthly migraine days from baseline to six months after the first injection. Safety and effectiveness are monitored throughout, with frequent assessments during both on-site and remote visits to ensure accurate tracking of migraine symptoms and any side effects.

Researchers are evaluating the effect of Xeomin injections compared to placebo injections for preventing episodic migraine. This phase 3 clinical trial focuses on adults who experience episodic migraine, aiming to measure changes in the number of migraine days per month. Participants must have a diagnosis of episodic migraine for at least 12 months and meet specific headache frequency criteria. Participants will receive four treatments of either Xeomin or placebo injections into muscles of the head and neck, with treatments spaced about 12 weeks apart. The entire trial lasts approximately 52 to 55 weeks, beginning with a screening period of 4 to 5 weeks. There are about 14 visits in total, with the first, last, and four treatment visits conducted on-site, while the other visits are held remotely via phone or video. Throughout the study, participants will track their migraine days using a headache diary, and researchers will assess changes in monthly migraine frequency from baseline to six months after the first injection. Regular monitoring includes both in-person and remote assessments. The primary outcome focuses on the change in monthly migraine days between baseline and month six after treatment initiation.

Researchers are evaluating the safety and effectiveness of KarXT in preventing relapse of psychosis symptoms in people aged 55 to 90 years who have psychosis associated with Alzheimer's Disease. This Phase 3 study is randomized, double-blind, placebo-controlled, and conducted at multiple outpatient centers. The main goal is to compare relapse prevention between KarXT treatment and placebo over 38 weeks, while also assessing time to discontinuation, safety, and tolerability. Participants receive either KarXT in varying doses (ranging from 20 mg/2 mg to 66.7 mg/6.67 mg taken three times daily) or placebo capsules. The study lasts 38 weeks, during which participants remain on assigned treatment in an outpatient setting. The randomized, double-blind design ensures neither participants nor researchers know who receives KarXT or placebo during the study. Throughout the study, participants will visit the clinic regularly for assessments of their psychosis symptoms, safety checks, and overall health. Researchers will track the time to relapse of psychosis symptoms as the primary outcome. They will also monitor safety and tolerability through clinical examinations and other evaluations. The total duration of participation is 38 weeks from randomization to the end of the study period.

Researchers are evaluating the safety and effectiveness of KarXT in adults aged 55 to 90 who have mild to severe Alzheimer's Disease (AD) accompanied by moderate to severe psychosis related to AD. This phase 3 study aims to better understand how KarXT compares to a placebo in treating the psychotic symptoms associated with Alzheimer's Disease. Participants must have documented AD diagnosis and a history of psychotic symptoms lasting at least two months prior to starting the study. Participants will receive either KarXT or a placebo, with specified doses given on designated days. The study is designed as a randomized, double-blind, placebo-controlled trial with parallel groups to assess the treatment's effects. Details about dosing schedules and administration are planned but not specified here. During the study, researchers will measure changes from baseline in the Neuropsychiatric Inventory-Clinician: Hallucinations and Delusions (NPI-C: H+D) score up to week 14 to evaluate the impact on psychosis symptoms. Participants will undergo brain imaging (MRI or CT) if not already done within the past five years to rule out other conditions, and safety monitoring including laboratory tests will be conducted. The total participation duration covers screening through at least 14 weeks of treatment and assessment.

Researchers are evaluating the effects of a medicine called rimegepant in adolescents aged 12 to less than 18 years who have frequent migraine attacks. Participants must have a history of migraine for at least 6 months, experience 15 or more headache days per month including 8 or more migraine days, and untreated migraine attacks lasting 4 to 72 hours. This Phase 3 study aims to assess the safety and effectiveness of rimegepant for migraine prevention in this age group. In the first part of the study, about half of the participants will receive a rimegepant tablet every other day, and the other half will receive a matching placebo tablet every other day. This phase will last for 3 months and is double-blind and placebo-controlled. In the second part, all participants who continue will receive rimegepant every other day for 1 year to evaluate long-term safety. Tablets are orally disintegrating and taken on or under the tongue. Participants will have up to 19 visits at the study clinic, approximately every 4 weeks, with some visits possibly occurring every 2 to 8 weeks. Home health visits may also take place. Each visit includes a health check and blood sample collection. Participants will complete a daily diary to record their migraine attacks. The main outcome measured is the number of migraine days per month over 12 weeks.

Researchers are investigating the long-term safety and tolerability of brivaracetam in participants diagnosed with childhood absence epilepsy or juvenile absence epilepsy. This phase 3 study focuses on those who have previously participated in related studies and aims to observe potential benefits and side effects over an extended period. Participants receive brivaracetam either as a film-coated tablet or as an oral solution, both given twice daily in equal doses. The treatment continues long-term, allowing researchers to monitor the effects of the medication in managing epilepsy in children and adolescents. During the study, participants are closely monitored for any treatment-emergent adverse events, including those that may lead to stopping the medication. Safety visits and assessments occur throughout the study, which may last up to three years, ensuring ongoing evaluation of the drug's impact and tolerability in this young population.

The trial investigates the long-term safety and tolerability of KarXT in people with psychosis associated with Alzheimer's Disease. This Phase 3 global, multicenter, open-label extension study lasts 52 weeks and enrolls participants who have completed earlier related studies (CN012-0026, CN012-0027, or CN012-0056). The purpose is to monitor how well patients tolerate KarXT over an extended period and to collect safety data. Participants receive KarXT in varying doses taken three times daily, ranging from 20/2 mg up to 66.7/6.67 mg per dose, corresponding to total daily doses between 60/6 mg and 200/20 mg. This treatment is provided throughout the 52-week open-label extension. The study includes only those who completed the previous related studies and continues to assess their response to KarXT over this longer timeframe. During the study, participants are closely monitored for treatment-emergent adverse events from the first dose through 14 days after the final dose, which may be up to 54 weeks. Regular assessments ensure safety and tolerability, and caregivers are involved to support participants. The study also evaluates participants' ability to continue living in their current setting and requires consent from the participant or their legal representative. Overall, the study tracks long-term safety outcomes in this specific patient group.
