Researchers are evaluating the safety and effectiveness of KarXT combined with KarX-EC in adults aged 55 to 90 who have agitation related to Alzheimer's Disease. This phase 3 study aims to better understand how these treatments impact agitation symptoms in this population by comparing them to a placebo group. Participants must have a confirmed Alzheimer's diagnosis and meet specific criteria for agitation severity to join the study. Participants will receive either the Xanomeline/Trospium Chloride Capsule, Xanomeline Enteric Capsule, or a placebo, each given at specified doses on designated days. The study is randomized, double-blind, and placebo-controlled to ensure reliable comparison of treatment effects. The treatment period lasts through Week 14, during which dosing schedules are closely followed. Throughout the study, participants will be regularly assessed using the Cohen-Mansfield Agitation Inventory-International Psychogeriatric Association (CMAI-IPA) to measure changes in agitation levels from baseline to Week 14. Caregivers will provide reports on participant status and help ensure medication compliance. Safety and symptom changes will be carefully monitored to evaluate the treatments' effects during this period.

Researchers are evaluating the safety and reactogenicity of mRNA-1195 in adults aged 18 to 55 years who have multiple sclerosis, including those with relapsing forms and early disease stages. This Phase 2, randomized, observer-blind, placebo-controlled study aims to better understand how this investigational vaccine performs in this population. Participants will receive either the mRNA-1195 vaccine or a placebo, both given as intramuscular injections. The study uses a dose-ranging design to compare different dosing levels. Injections will be given according to the study schedule, and participants will be monitored closely throughout the trial. During the study, participants will be assessed for local and systemic reactions up to 7 days after each injection, and for any unsolicited adverse events up to 28 days after each injection. Medically attended adverse events will be tracked for up to 6 months after the last injection, and serious adverse events or those leading to discontinuation will be followed until the end of the study at approximately 887 days. Safety and reactogenicity data will be collected through physical exams, laboratory tests, and medical evaluations.

PRAX-628-321 (POWER1) is a double-blind, randomized, multicenter, trial to evaluate the efficacy and safety of PRAX-628 in adults who can attest to concurrently taking at least 1, but no more than 3 acceptable anti-seizure medications.

Researchers are evaluating the long-term safety of rimegepant for treating acute migraine in children and adolescents aged 6 to under 18 years. This Phase 3, open-label study focuses on young individuals with a history of migraine with or without aura, aiming to understand the safety and tolerability of this treatment over time. Participants receive rimegepant orally in doses of 75 mg, 50 mg, or 35 mg orally disintegrating tablets (ODT) as needed for migraine attacks. The study monitors treatment over an extended period to assess ongoing safety and tolerability in a pediatric population. Throughout the study, participants will be regularly evaluated for any adverse effects, including serious events, events leading to discontinuation, and significant lab abnormalities. Safety assessments are conducted over 58 weeks, with careful monitoring to ensure participant well-being and collect comprehensive safety data.

This research aims to test the safety and effectiveness of BHV-3000 (rimegepant) compared to a placebo for treating moderate to severe migraine attacks in children and adolescents aged 6 to under 18 years. The study focuses on pediatric migraine, including attacks with or without aura, lasting more than 3 hours and occurring 1 to 8 times per month over the previous two months. Participants must be able to clearly distinguish migraine from other headaches and weigh more than 40 kg. Participants will receive either BHV-3000 (rimegepant) at doses of 75 mg or 50 mg as an orally disintegrating tablet (ODT) or a matching placebo. The study is randomized, double-blind, and placebo-controlled, designed to evaluate the acute treatment effect. Some participants may continue stable migraine preventive medications, but use of CGRP antagonist drugs is not allowed. The treatment phase will monitor responses to the study drug during migraine attacks. During the study, participants will be assessed for migraine pain relief two hours after dosing, measuring how many experience complete freedom from pain. Blood samples will be taken, and participants will be monitored for safety and side effects. The study excludes those with certain headache types, significant psychiatric or neurological conditions, recent surgeries, or other serious medical issues that could affect participation or safety. Overall, the study evaluates both the effectiveness and safety of rimegepant in a pediatric population over the course of migraine attacks.

Migraine is a common neurological disorder causing moderate to severe headaches, often with nausea, vomiting, and sensitivity to light and sound. It is especially disabling in children and adolescents. This trial evaluates the safety and effectiveness of ubrogepant, a drug approved for adults, for the acute treatment of migraine in children and adolescents aged 6 to 17 years. The study is a Phase 3, multicenter, randomized, double-blind, placebo-controlled trial. Participants aged 6 to 11 years in a pharmacokinetic (PK) cohort will receive one of two doses of ubrogepant to determine the best dose for the main study. In the main study, children and adolescents will be randomized to receive either a low or high dose of ubrogepant or a placebo, with a one in three chance of receiving placebo. The study treatment is given as oral tablets during qualifying migraine attacks, with an option for a second dose or rescue medication at least 2 hours after the initial dose if the headache remains moderate or severe. Approximately 1059 participants will be enrolled across about 120 sites in the United States. Participants will attend regular hospital or clinic visits throughout the study, which lasts up to 6 months. Researchers will monitor the effects of the treatment through medical assessments, blood tests, side effect checks, and questionnaires. The primary outcome is the percentage of participants aged 6 to 17 years who experience freedom from pain 2 hours after the initial dose. The study includes safety monitoring and evaluates tolerability and pharmacokinetics of ubrogepant in this age group.
