Researchers are investigating the effectiveness, safety, and tolerability of combining baxdrostat with dapagliflozin compared to dapagliflozin alone in people with chronic kidney disease (CKD) and high blood pressure. This Phase III, international, multicenter, double-blind, placebo-controlled study aims to see if this combination reduces risks such as significant kidney function decline, kidney failure, heart failure events, or cardiovascular death. The study includes a 4-week run-in period where participants not previously treated with SGLT2 inhibitors receive dapagliflozin alone. After this, participants are randomly assigned to receive either baxdrostat plus dapagliflozin or placebo plus dapagliflozin in a double-blinded manner. Study visits occur frequently initially (at 2, 4, 8, 16, 34, and 52 weeks after randomization) and then approximately every 4 months. If participants stop the blinded treatment early, they continue dapagliflozin alone unless specific criteria require its discontinuation. Participants will undergo regular assessments including blood pressure monitoring and laboratory tests related to kidney function and cardiovascular health. The primary outcome measures the reduction in risk of major kidney and heart events over up to 37 months. Even if participants stop the study treatment, they will continue follow-up visits and data collection to ensure comprehensive safety and efficacy evaluation throughout the study duration.

Researchers are evaluating the effectiveness and safety of brenipatide when given along with standard care compared to a placebo with standard care in adults with bipolar disorder. This Phase 2 study aims to see if brenipatide can delay the worsening of bipolar symptoms. The trial includes participants aged 18 to 75 years and involves a careful assessment of how well the treatment works and its safety profile. The trial has three main periods: a screening period lasting about one month, a treatment period of at least six months, and a follow-up period of around two months. Participants receive either brenipatide or placebo, both given by subcutaneous injection, alongside their usual bipolar disorder medications. The study may end earlier if symptoms worsen or if participants withdraw for any reason. Participants will be asked to self-inject the study medication, maintain diaries, complete questionnaires, and attend regular visits throughout the study. Researchers will monitor the time to relapse, defined as the number of days from randomization until symptoms worsen according to specific criteria, over at least six months. Safety and adherence to treatment will also be closely observed during the study.

Researchers are evaluating the safety and effectiveness of adding KarXT (Xanomeline/Trospium Chloride) to standard treatment for mania in adults with Bipolar-I Disorder. This Phase 3, randomized, double-blind study focuses on individuals experiencing acute manic episodes, with or without mixed features, who are already taking lithium, valproate, or lamotrigine. The study aims to measure changes in mania symptoms using the Young Mania Rating Scale at Week 5. Participants will be randomly assigned to receive either KarXT or a placebo alongside their stable dose of lithium, valproate, or lamotrigine. The doses of these medications are specified and given on set days during the study. Only those with stable mood stabilizer doses for at least two weeks prior to screening, and valproate treatment for at least seven months, are eligible. The treatment period lasts for 5 weeks. During the study, participants will be closely monitored through psychiatric evaluations and clinical assessments. Researchers will assess mania severity, safety, and any side effects. The main outcome is the change from baseline in the Young Mania Rating Scale score at Week 5. Participants’ physical health, including liver function and risk of urinary or gastrointestinal issues, will also be monitored to ensure safety throughout the trial.

Researchers are evaluating the effectiveness and safety of KarXT for treating schizophrenia in adolescents aged 13 to 17 years. This Phase 3 study focuses on adolescents who meet diagnostic criteria for schizophrenia and experience symptoms of psychosis. The study aims to better understand how KarXT may impact symptoms as measured by a standard schizophrenia rating scale. Participants will receive either KarXT or a matching placebo at specified doses on specific days. The study is randomized, double-blind, and placebo-controlled, meaning neither the participants nor the researchers know who receives the active drug or placebo during the trial. During the study, researchers will assess changes in schizophrenia symptoms using the Positive and Negative Syndrome Scale (PANSS) after 5 weeks of treatment. Participants will be monitored for safety and symptom changes throughout the study period. The goal is to gather detailed information about KarXT's impact on schizophrenia symptoms in this adolescent population.

Researchers are evaluating the effectiveness and safety of remibrutinib in adults aged 18 to 65 years with secondary progressive multiple sclerosis (SPMS). This Phase III study is randomized, double-blind, and placebo-controlled, designed to better understand how remibrutinib affects disability progression in SPMS patients over time. Participants will be randomly assigned to receive either oral remibrutinib tablets or matching placebo tablets during the Core Part of the study, which is event-driven and double-blinded. After this period, all participants may enter an Extension Part where they receive open-label remibrutinib treatment. This design allows researchers to compare remibrutinib against placebo and then monitor long-term effects when all participants receive the active drug. Throughout the study, participants will undergo regular assessments including MRI scans and clinical evaluations to track changes in disability using the Expanded Disability Status Scale (EDSS). The primary outcome measured is the time to confirmed disability progression over six months, with follow-up lasting up to approximately five years. Safety, tolerability, and other health parameters will also be closely monitored during both study phases.

Researchers are assessing the long-term safety and tolerability of two treatments, KarXT and KarX-EC, for adolescents with schizophrenia and children and adolescents with irritability related to autism spectrum disorder. This Phase 3, multicenter, open-label study includes participants aged 5 to 17 years and aims to monitor how these treatments are tolerated over time in these specific populations. Participants receive KarXT or a combination of KarXT and KarX-EC at specified doses on designated days. The study includes adolescents aged 13 to 17 years with schizophrenia and children and adolescents aged 5 to 17 years with autism-related irritability. Treatment is administered openly, meaning both researchers and participants know the treatment being given. Throughout the study, researchers will evaluate participants for any treatment-emergent adverse events, adverse events of special interest, and serious adverse events for up to 54 weeks. Safety assessments include monitoring physical examinations, vital signs, and ECGs. Participants must have completed earlier related studies without safety concerns to join, and their health will be closely monitored during the study to ensure safety and tolerability.

Researchers are evaluating the long-term safety and effectiveness of pembrolizumab (MK-3475) in participants with advanced solid tumors or blood cancers who have previously taken part in other pembrolizumab-based studies. This phase 3 study includes participants who are either currently on treatment or in follow-up from prior parent studies. It aims to understand how well pembrolizumab works over an extended period, up to approximately 10 years, by observing overall survival and safety outcomes. The study has three phases: First Course Phase, Survival Follow-up Phase, and Second Course Phase. Participants who were receiving pembrolizumab, pembrolizumab-based combinations, or lenvatinib in their parent studies will continue treatment in the First Course Phase, completing up to 35 doses every 3 weeks or 17 doses every 6 weeks. Those in the Follow-up Phase will enter the Survival Follow-up Phase without additional treatment but will be monitored. Participants eligible for a Second Course Phase, who have not received other anticancer treatments since their prior pembrolizumab dose and meet health criteria, may receive up to 17 doses every 3 weeks or 8 doses every 6 weeks of pembrolizumab or its combinations. Some may also receive other study drugs such as olaparib, MK-4280, MK-4280A, or pembrolizumab with berahyaluronidase alfa. Participants will be involved in regular treatment visits, safety checks, and long-term monitoring for up to about 10 years to assess overall survival. Researchers will evaluate clinical outcomes, monitor any side effects, and check organ function and physical health status. The study includes detailed eligibility screening, including physical assessments and adherence to contraception requirements for women of childbearing potential. Safety follow-up is ongoing to ensure participant well-being throughout the study.

Researchers are evaluating an organ dysfunction scoring system adapted specifically for pregnant and early postpartum patients admitted to intensive care units (ICUs). The study aims to develop and validate this obstetric SOFA score (SOFA-OBS) to better predict ICU mortality and sepsis-related mortality in this group. The current general SOFA score does not account for physiological changes during pregnancy and early postpartum, such as reduced creatinine levels and lower blood pressure, which may affect its accuracy in these patients. This study will include about 130 female participants who are either pregnant at any stage or within three days after giving birth and require ICU care. The study will use the new SOFA-OBS score that adjusts kidney and cardiovascular measures to reflect pregnancy changes and simplifies respiratory function evaluation by using a non-invasive pulse oximeter when arterial blood gases are unavailable. The original neurologic, liver, and platelet assessments remain unchanged. Researchers will collect data routinely gathered during ICU care without additional interventions. They will track SOFA and SOFA-OBS scores daily during ICU stays, up to discharge or death, focusing on the first 24 and 48 hours, and assess various organ functions and sepsis definitions adapted to pregnancy stages. Participants will be monitored throughout their ICU stay with data recorded on organ function, infection status, interventions, and outcomes. The study will compare SOFA-OBS with the general SOFA score for predicting mortality and sepsis outcomes. Data collection will include laboratory tests, vital signs, and clinical assessments using standardized forms and electronic systems. Safety and privacy will be maintained, and consent obtained before participation. The total duration depends on ICU stay, with daily evaluations until discharge or death, or up to 28 days post-enrollment for mortality outcomes.

Researchers are evaluating how well seltorexant works and its safety as an added treatment to antidepressants in adults and elderly participants who have major depressive disorder with insomnia symptoms (MDDIS). The study focuses on people who have not responded adequately to current antidepressant therapy with selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitors (SNRIs). This Phase 3 trial aims to assess the improvement of depressive symptoms and the maintenance effect of seltorexant compared to a placebo. Participants will receive either seltorexant or a matching placebo taken orally alongside their current antidepressant medication, which includes SSRIs or SNRIs. The study is divided into two parts: Part 1 evaluates changes in depression severity after 43 days, while Part 2 monitors the time to relapse for up to nearly three years in participants who achieved a stable response. Participants must continue their stable antidepressant dose during the study. During the study, participants will be assessed using the Montgomery-Asberg Depression Rating Scale to measure changes in depression symptoms and monitored for relapse over time. Safety and tolerability will also be evaluated throughout. The total participation includes an initial treatment phase and an extended maintenance phase, allowing researchers to understand both short-term and long-term effects of seltorexant as an adjunctive therapy.

Chagas disease is a parasitic infection caused by Trypanosoma cruzi, affecting millions worldwide, particularly in Latin America. This research evaluates shorter treatment regimens of benznidazole, aiming to improve safety and maintain effectiveness compared to the standard long treatment. The study is a Phase III clinical trial focusing on adults with chronic Chagas disease in the indeterminate or mild cardiac phase, assessing whether shorter 14-day and 28-day regimens are not worse than the standard 60-day treatment. The trial involves three treatment groups receiving benznidazole at 300 mg daily divided into three doses. One group receives the drug for 2 weeks, another for 4 weeks, and the standard group for 8 weeks. The medication is taken orally as 100 mg tablets every 8 hours. The study compares efficacy and safety among these regimens, monitoring for parasite clearance and adverse events. Participants will undergo regular assessments including qualitative PCR tests to detect parasite presence from the end of treatment up to 12 months after. Safety is evaluated by tracking the frequency and severity of side effects. Researchers will also monitor treatment adherence and perform clinical exams, ECGs, and echocardiograms. The total participation duration includes treatment plus a year of follow-up to confirm sustained parasite clearance and safety.
