Researchers are conducting a Phase 3 clinical trial to study the effects of relutrigine in people with developmental and epileptic encephalopathies (DEEs). The study is designed to evaluate the drug's efficacy, safety, tolerability, and how the body processes it compared to a placebo. This trial includes participants aged 2 to 65 years who have experienced seizure onset before age 12 and have a confirmed diagnosis of DEE. Participants will be randomly assigned to receive one of two doses of relutrigine (1.0 mg/kg/day or 1.5 mg/kg/day) or a placebo. The medication is given once daily either by mouth or through a gastrostomy or jejunostomy tube. After the initial double-blind treatment period, there is an open-label extension where all participants may receive the study drug. During the study, participants will be monitored for changes in seizure frequency over 16 weeks as the primary outcome. Safety and tolerability will also be assessed throughout the trial. Various evaluations, including heart monitoring and seizure tracking, will be conducted to ensure participant well-being. The overall study will track participants from screening through treatment and follow-up phases to gather comprehensive data about relutrigine's effects.

This research focuses on men with prostate cancer who have previously participated in an enzalutamide clinical study sponsored by Astellas or Medivation. It aims to gather long-term safety information from participants who continue to benefit from enzalutamide treatment. This is a Phase 2 open-label extension study designed to monitor ongoing treatment effects after the initial study has completed its primary analysis or evaluation period. Participants will continue their previous treatment regimens, which may include enzalutamide taken orally once daily. Some may also receive abiraterone acetate with prednisone or leuprolide acetate depending on their prior study enrollment. Dose adjustments are allowed with medical monitor approval. The first visit of this study should occur within seven days of the last visit of the prior study unless treatment is temporarily paused. Participants are asked to return to their study site every 24 weeks for safety reviews, including adverse event monitoring and medication checks. At visits every 12 weeks, participants return unused study drugs and receive new supplies if needed. Safety data, including all adverse events and serious adverse events, are collected from consent until study completion, which may last up to 96 months. The study follows local standard care guidelines and includes a post-marketing phase in South Korea.

Researchers are evaluating the safety and effectiveness of IPN10200, a medication designed to prevent episodic and chronic migraines in adults aged 18 to 80. Migraines cause severe throbbing pain often accompanied by nausea and sensitivity to light and sound, caused by brain activation releasing pain-related chemicals. IPN10200 works by stopping the release of these chemical messengers, and this phase II study aims to find the right dose that balances safety and efficacy. The study has three periods: first, a screening to check eligibility; second, Step 1 where two different doses of IPN10200 are tested sequentially in two groups, with injections given into muscles of the head, face, and neck and safety monitored over 36 weeks; third, Step 2 where new participants with episodic or chronic migraine are randomly assigned to receive one of two doses or a placebo, also via injections in the same areas, with monitoring continuing until Week 36. Participants will complete a daily electronic migraine diary and questionnaires throughout the study lasting up to 44 weeks. Researchers will monitor safety by tracking adverse events, laboratory changes, vital signs, facial exams, ECG readings, and antibody development. They will also measure changes in monthly migraine days to evaluate treatment effectiveness while ensuring participant safety throughout the study.

Researchers are evaluating trastuzumab deruxtecan (T-DXd) in adults with unresectable or metastatic breast cancer that is either HER2-low or HER2 IHC 0. This includes patients with hormone receptor-negative or hormone receptor-positive cancer. The study aims to assess the safety and effectiveness of T-DXd by measuring the time patients benefit from the treatment before needing another anticancer therapy. Participants receive T-DXd through an intravenous infusion at a dose of 5.4 mg/kg on the first day of each 21-day cycle. Treatment continues until the disease progresses based on imaging, unacceptable side effects occur, other reasons for stopping arise, or for up to two years after the first dose. The study is open-label, multicenter, and global, focusing on patients who have not previously received anti-HER2 therapy for metastatic disease. During the study, researchers will monitor participants regularly with imaging scans to measure disease progression and collect biopsies. They will also assess heart function, organ health, and overall clinical status. The main outcome is the time from starting T-DXd to the start of the next anticancer treatment or death, followed for up to 24 months. Safety and side effects will be closely observed throughout the study.
