Researchers are evaluating the safety and tolerability of TAK-861 in people with narcolepsy type 1 (NT1) who have already been exposed to TAK-861 in earlier studies. The study also aims to observe improvements in symptoms such as excessive daytime sleepiness and the frequency of cataplexy episodes. This long-term extension trial continues from previous phase 2 and phase 3 trials and includes participants who completed those earlier studies. All participants in this trial will receive TAK-861 tablets. Those who were previously given a placebo in parent trials will be randomly assigned to a dose of TAK-861. The study plans to enroll up to 500 participants worldwide and will last approximately 5 years, or until the study is stopped or the drug is approved and launched. Participants will visit clinics multiple times, with some visits possibly done at home, and will have a follow-up check 4 weeks after their last dose. During the study, participants will be monitored for treatment-emergent adverse events from the time they consent until 4 weeks after their final dose, covering up to about 5 years. Researchers will assess safety and tolerability regularly through these visits and follow-ups. The focus is on identifying any side effects and understanding the long-term effects of TAK-861 in people with NT1.

Researchers are evaluating the effectiveness and safety of BHV-7000 in adults with refractory focal onset epilepsy, a condition where seizures originate in one area of the brain and do not respond well to current treatments. This Phase 2/3 clinical trial aims to determine whether BHV-7000 can reduce seizure frequency in this population. The study is divided into two parts. In Part A, participants are randomly assigned to receive either 25 mg or 50 mg of BHV-7000, or a matching placebo, taken once daily. After completing Part A, participants move to Part B, where they are randomized to receive 75 mg of BHV-7000 or a matching placebo, also taken once daily. Both parts are randomized and double-blinded to ensure unbiased results. Participants will be monitored from Week 8 to Week 20 of each part for changes in average seizure frequency, serious adverse events, discontinuations due to side effects, and laboratory abnormalities. Researchers will track seizure diaries and assess safety and tolerability throughout the study. The total duration includes both study parts with regular evaluations to measure the drug’s impact and participant safety.

Researchers are evaluating the effectiveness and safety of TAK-861 for treating narcolepsy type 1 (NT1), a condition that includes narcolepsy with cataplexy. This Phase 3 trial aims to see how well TAK-861 works and whether its benefits last over time. The study also monitors any side effects or adverse events related to taking or stopping the medication in people with NT1. All participants will start by taking TAK-861 tablets during an open-label treatment period. After this period, those who meet certain criteria will be randomly assigned to continue TAK-861 at their current dose or switch to placebo tablets in a double-blind randomized withdrawal period lasting up to 4 weeks. If symptoms worsen during this withdrawal phase and sleepiness scores rise above a set level, participants will stop the study treatment and may join a separate long-term extension study or be followed for 4 weeks after their last dose. Participants will be assessed using the Epworth Sleepiness Scale to measure daytime sleepiness and will undergo monitoring for safety and side effects throughout the study. The trial is planned to include about 88 participants worldwide, aged 16 to 70 years, and involves careful follow-up to observe how the treatment impacts their narcolepsy symptoms over time.

This research aims to evaluate the long-term safety and tolerability of pelacarsen (TQJ230) in adults with established cardiovascular disease and elevated Lipoprotein(a) who have completed the parent trial CTQJ230A12301. The study is an open-label extension following the phase 3 parent study, providing participants continued access to pelacarsen after the initial trial. Participants will receive pelacarsen 80 mg by subcutaneous injection once a month during this open-label extension. The study is single-arm and multicenter, focusing on continued treatment with pelacarsen for up to 36 months after completion of the parent study. Throughout the study, participants will be monitored regularly to assess safety and tolerability, with particular attention to adverse events occurring up to 36 months. Researchers will collect data on health status throughout this period to understand the long-term effects of pelacarsen in this patient population.
