Researchers are evaluating the effect of Xeomin injections compared to placebo injections for preventing chronic migraine. This Phase 3, randomized, double-blind, placebo-controlled trial includes an extension period and aims to measure changes in the number of monthly migraine days. Participants have chronic migraine and meet specific criteria related to headache frequency and migraine history. Participants receive Xeomin or placebo injections into muscles of the head and neck at pericranial and cervical points. The study includes two Xeomin dose groups and a placebo group during the controlled period, with all groups receiving Xeomin in the extension phase. Four treatments are given approximately 12 weeks apart over a total study duration of 52 to 55 weeks. Participants take part in 14 visits over the study period, with the first, last, and four treatment visits conducted in person and the remaining eight visits by phone or video call. Researchers collect headache and migraine data from diaries and assess changes in monthly migraine days as the primary outcome. Safety is monitored by tracking treatment-related adverse events throughout the trial.

Researchers are evaluating the use of Xeomin injections to prevent episodic migraine. This Phase 3 clinical trial compares Xeomin to placebo injections in the muscles of the head and neck to measure changes in the number of monthly migraine days. Participants have episodic migraine with or without aura, and the study aims to assess the efficacy and safety of different Xeomin doses over time. Participants receive a series of four Xeomin or placebo injections spaced about 12 weeks apart. The study includes two experimental groups receiving different Xeomin doses and a placebo group, followed by an extension period where some participants receive Xeomin. Injections are given at specific points around the head and neck. The trial lasts approximately 52 to 55 weeks, starting with a 4 to 5 week screening period. Participants attend about 14 visits, including the first and last visits and four treatment visits conducted on-site, with other visits done remotely by phone or video call. Researchers monitor changes in monthly migraine days, headache days, and medication use, as well as any treatment-related side effects throughout the study.

Researchers are evaluating how fisetin, a dietary supplement, behaves in the body of healthy adults in two age groups young adults aged 18 to 30 years and older adults aged 65 years or older. The study aims to describe the kinetics of fisetin after a single oral dose in older adults and to compare these kinetics between young and old age groups. This trial is designed as an open-label, four-arm, cross-over study involving fasted and fed conditions to assess differences in fisetin absorption and metabolism. Participants will receive a single oral dose of 500 mg fisetin as capsules with water either after overnight fasting or following a high-caloric, high-fat meal recommended by the FDA for food-effect studies. Each participant will complete all four arms in random order with at least a one-week washout period between arms. The fed meal includes toast with butter, fried eggs, hash brown potatoes, and whole milk. Urine collection and blood sampling will be conducted to measure fisetin and its metabolites. During each kinetic visit, 24 blood samples will be drawn over 10 hours to track fisetin levels in plasma, with a total blood volume of 164 ml per arm. Participants will stay in the clinical research unit for 10 hours post-dose, during which blood pressure and heart rate will be monitored for the first 4 hours. They will also drink sparkling water hourly to aid digestion. Urine will be collected for 10 hours after dosing to assess fisetin excretion. The studys main outcomes focus on fisetin plasma concentrations under different conditions and across age groups.

Researchers are evaluating the persistence of two treatments, upadacitinib UPA and tumor necrosis factor inhibitors TNFi, in adults with moderate to severe active rheumatoid arthritis RA. This observational study is conducted in Germany with about 678 participants across roughly 80 sites. The purpose is to compare how long participants continue their prescribed treatment under real-world conditions over time. Participants will receive either UPA or TNFi treatment as prescribed by their doctors, following local labels and standard care practices. Treatment decisions were made before joining the study and are independent of recruitment. The study will observe participants for up to 24 months to assess retention rates on these treatments. During the study, participants will be monitored regularly according to local care standards. Researchers will collect data on how long participants stay on their assigned treatment, focusing on retention rates over approximately 24 months. Study participation may last up to two years, with recruitment expected to take about 24 months, resulting in a total study duration of about 48 months.

Researchers are evaluating the efficacy and safety of volrustomig compared to observation in participants with unresected locally advanced head and neck squamous cell carcinoma LA-HNSCC who have not progressed after receiving definitive concurrent chemoradiotherapy cCRT. This phase III, randomized, open-label global study aims to assess whether volrustomig can improve outcomes in this patient population. Participants are randomly assigned to one of two groups those who receive volrustomig as sequential therapy, and those who undergo observation without additional treatment. The study compares these two approaches following prior curative concurrent chemoradiotherapy. The trial includes long-term follow-up to monitor patient outcomes. During the study, participants will be regularly assessed for progression-free survival, overall survival, physical functioning, and quality of life. Researchers will also monitor for the presence of anti-drug antibodies and adverse events related to volrustomig. Follow-up evaluations may continue for up to approximately eight years to fully understand the treatment impact and safety profile.

Researchers are evaluating the long-term safety and tolerability of dazodalibep in people with Sjgrens Syndrome. This phase 3 open-label study extends previous trials by continuing to monitor participants who completed 48 weeks of treatment with dazodalibep or placebo. The study is sponsored by Amgen and aims to better understand the safety profile of dazodalibep over an extended period. Participants who finished the initial 48-week trials HZNP-DAZ-301 or HZNP-DAZ-303 will receive an assigned dose of dazodalibep intravenously for an additional 132 weeks. This extension study involves a single treatment group receiving dazodalibep without placebo, focusing on ongoing treatment effects and participant safety. During the study, participants will be monitored for treatment-emergent adverse events for up to 152 weeks. Researchers will also measure the presence of anti-drug antibodies and plasma concentrations of dazodalibep for up to 132 weeks. Participants need to be available for all study visits and procedures, with safety assessments conducted regularly throughout the long-term extension period.

Researchers are evaluating the real-world effectiveness, safety, and patient compliance of ribociclib combined with an aromatase inhibitor for adjuvant treatment in patients with hormone receptor-positive, HER2-negative early breast cancer at high risk of recurrence. This observational study also compares ribociclib treatment with abemaciclib plus endocrine therapy and endocrine therapy alone, aiming to better understand treatment decisions and clinical adoption in routine practice. The study is conducted across breast centers and gynecological practices to represent typical healthcare settings. Participants receive treatment based on their physicians clinical judgment without randomization or intervention assignment. The study collects data from patients treated with ribociclib plus aromatase inhibitor with or without luteinizing hormone-releasing hormone LHRH, abemaciclib plus endocrine therapy with or without LHRH, or endocrine therapy alone with or without LHRH. Baseline data and follow-up information on adverse events, quality of life, treatment adherence, and socio-economic factors are gathered over time. During the study, participants undergo assessments including evaluation of invasive disease-free survival up to 36 months, quality of life questionnaires, medication adherence reports, and monitoring of adverse events and treatment changes. Data on reasons for treatment decisions, patient perceptions, and healthcare provider involvement are also collected. The study duration extends up to 39 months to provide a comprehensive overview of treatment impact and patient experience in real-world clinical settings.

Researchers are evaluating petosemtamab compared with investigators choice monotherapy in patients with incurable metastatic or recurrent head and neck squamous cell carcinoma HNSCC who have previously been treated. This phase 3 open-label, randomized controlled study focuses on patients whose disease has progressed after anti-PD-1 and platinum-containing therapies. It aims to assess effectiveness and safety for second- and third-line treatments in this population. Participants will be randomly assigned to receive either petosemtamab or one of several investigators choice monotherapies, including cetuximab, methotrexate, or docetaxel. The treatments are given as part of a controlled multicenter trial. The study includes follow-up periods to evaluate responses and safety outcomes over time. During the study, participants will undergo regular assessments including radiologic evaluations to measure tumor response according to RECIST criteria, physical performance status checks, and laboratory tests to monitor organ function and adverse events. Researchers will track overall survival for up to approximately three years and evaluate other outcomes such as progression-free survival, response rates, quality of life measures, and treatment safety. The total duration of participation is aligned with treatment and outcome measurement timelines as specified.

Researchers are investigating the effectiveness and safety of combining petosemtamab with pembrolizumab compared to pembrolizumab alone as first-line treatment for recurrent or metastatic PD-L1 positive head and neck squamous cell carcinoma HNSCC. This Phase 3 randomized, open-label study focuses on patients who have not received previous systemic therapy for incurable recurrent or metastatic disease and aims to improve treatment outcomes in this population. Participants will be randomly assigned to receive either the combination of petosemtamab plus pembrolizumab or pembrolizumab alone. The study excludes patients previously treated with anti PD-L1 or anti-EGFR therapies, with some exceptions for local treatments like cetuximab under specific conditions. The treatments will be administered as part of the trial, with researchers comparing the two approaches over the treatment period. During the study, participants will undergo regular evaluations including tumor assessments based on RECIST v1.1 criteria, health-related quality of life questionnaires, and safety monitoring for adverse events. The main outcomes measured include overall survival and objective response rate up to approximately three years. Additional assessments include progression-free survival, duration of response, and pharmacokinetics. These activities aim to provide comprehensive data on how well the treatments work and their safety profiles throughout the study period.

Researchers are evaluating AZD0780, an oral PCSK9 inhibitor, in a phase 3, randomized, placebo-controlled study. This trial focuses on patients with established atherosclerotic cardiovascular disease ASCVD or those at high risk for a first ASCVD event. The study aims to assess how AZD0780 compares to placebo in reducing the risk of major adverse cardiovascular events, also known as MACE-PLUS, over the course of the trial. Participants are randomly assigned to receive either oral AZD0780 once daily or a matching placebo once daily. The study continues until a primary analysis censoring date, which may be up to approximately 54 months from randomization. After this, a study closure visit will be conducted as the final visit for each participant. During the study, participants will be regularly monitored for cardiovascular events including heart attacks, strokes, urgent coronary revascularizations, and other related outcomes. Researchers will track the time to first occurrence of these events as the primary outcome. Safety and other secondary outcomes like all-cause mortality will also be assessed. The total participation time can last up to about 54 months, with ongoing evaluations throughout this period.
