Researchers are evaluating whether the drugs retatrutide and tirzepatide can prevent major adverse liver outcomes (MALO) in adults with metabolic dysfunction-associated steatotic liver disease (MASLD) who are at high risk. This Phase 3 trial enrolls about 4,500 adults with MASLD identified by non-invasive tests indicating an increased likelihood of developing serious liver problems. The study aims to understand how these treatments might affect liver health over time compared to a placebo. Participants will be randomly assigned to receive either retatrutide, tirzepatide, or a placebo, all given by subcutaneous injection. The study will last approximately 224 weeks, during which participants may attend 25 to 30 clinic visits for monitoring and assessment. After the main study, eligible participants can join an optional 2-year extension where all will receive either retatrutide or tirzepatide regardless of their original group. Throughout the trial, participants’ liver function and disease progression will be closely monitored through various health assessments. Researchers will track the time to the first major adverse liver event as the main outcome. Safety and health status will be evaluated regularly during clinic visits, ensuring thorough observation over the long study period.

Researchers are investigating the safety, tolerability, and effectiveness of two dosing regimens of itepekimab compared to placebo as an add-on to intranasal corticosteroids in adults with chronic rhinosinusitis with nasal polyps (CRSwNP) that is not well controlled. This multinational Phase 3, randomized, double-blind, placebo-controlled trial involves male and female participants aged 18 years and older living with CRSwNP. Participants are randomly assigned to one of three groups receiving either itepekimab injections or placebo injections, both administered subcutaneously, alongside mometasone furoate nasal spray delivered intranasally. The study includes a 4-week screening period, followed by a 52-week treatment phase, and a 20-week safety follow-up, totaling up to 76 weeks. Participants transitioning to an extension study (LTS18420) will have a total duration of 56 weeks. Study visits include nine site visits and 20 phone or home visits. During the trial, participants will undergo assessments including endoscopic Nasal Polyp Scores (NPS) and Nasal Congestion Scores (NCS) measured from baseline to week 24 to evaluate changes. Researchers will monitor safety and tolerability throughout, with regular evaluations involving symptom severity, treatment adherence, and adverse events. The study aims to understand how well itepekimab works and is tolerated as an additional treatment for CRSwNP over the study duration.

Researchers are evaluating the effects of iptacopan compared with a placebo in adults aged 18 to 85 years who have generalized Myasthenia Gravis positive for acetylcholine receptor antibodies (AChR+ gMG). This Phase III, randomized, double-blind, placebo-controlled, multicenter study aims to assess the efficacy, safety, and tolerability of iptacopan while participants continue their stable standard of care treatments. The study includes participants with moderate to severe gMG symptoms and positive diagnostic criteria. Participants will be randomly assigned in a 1:1 ratio to receive either iptacopan or a matching placebo in the form of hard gelatin capsules for six months (180 days). During this time, they will continue their stable standard of care treatments. After the double-blind treatment period, a maximum 60-month open-label extension phase is offered. Safety follow-up assessments will occur one week and one month after the last dose of study treatment. During the study, participants will be evaluated for changes in their Myasthenia Gravis Activity of Daily Living (MG-ADL) total score from baseline to month 6. Researchers will monitor safety and tolerability throughout the treatment and extension periods. Vaccination status, infection monitoring, and regular clinical assessments will be part of participant evaluations to ensure safety and track disease symptoms over time.

Researchers are evaluating treatments for adults with relapsed or refractory multiple myeloma who have previously received an anti-CD38 antibody and lenalidomide. The study compares the effectiveness of talquetamab combined with pomalidomide (Tal-P), talquetamab combined with teclistamab (Tal-Tec), and investigator's choice between two standard regimens: elotuzumab with pomalidomide and dexamethasone (EPd), or pomalidomide with bortezomib and dexamethasone (PVd). This Phase 3 trial aims to understand which combination best controls the disease progression. Participants will receive talquetamab as a subcutaneous injection, pomalidomide orally, teclistamab as a subcutaneous injection, elotuzumab intravenously, dexamethasone either orally or intravenously, and bortezomib as a subcutaneous injection. The study involves comparing these combinations with varying administration routes. The trial includes multiple treatment arms to assess different drug combinations in patients who have undergone 1 to 4 prior therapies. During the study, participants will be monitored for progression-free survival up to 3 years and 5 months. Researchers will regularly assess disease status, treatment response, and safety. Participants' performance status will be evaluated, and adherence to treatment and potential side effects will be carefully tracked. This long-term observation will help determine how well each treatment combination controls the disease over time.

Researchers are evaluating the safety and effectiveness of brenipatide at different doses compared with a placebo in adults with uncontrolled moderate to severe asthma. This Phase 2 study focuses on participants who have a history of asthma requiring controller medication and recent severe asthma exacerbations. The goal is to better understand how brenipatide impacts asthma control over an extended period. Participants will receive either brenipatide or a placebo, both administered by subcutaneous injection. The study includes a 52-week treatment period during which the effects of the drug on asthma exacerbations and symptoms will be monitored. This randomized, double-blind approach helps compare the responses between the treatment and placebo groups. Study involvement lasts about 65 weeks, covering screening, treatment, and follow-up phases. During the study, researchers will assess participants' asthma control using questionnaires and track the annual rate of asthma exacerbations. Safety and treatment responses will be closely monitored throughout the trial to evaluate the drug's impact and participant well-being.

Researchers are evaluating LP352, a treatment for seizures in children and adults with Developmental and Epileptic Encephalopathies (DEE), including Lennox-Gastaut Syndrome (LGS) and other DEE types. This Phase 3, double-blind, randomized, placebo-controlled study aims to assess the effectiveness, safety, and tolerability of LP352. The study involves participants aged 2 to 65 years who experience multiple types of motor seizures and have a history of developmental plateauing or regression. Participants will receive either LP352 or a matching placebo, administered orally or through a gastrostomy tube if needed. The study includes several phases: Screening, a Titration period to adjust dosing, a Maintenance period to continue treatment, followed by a Taper period to gradually reduce the medication, and a final Follow-Up phase. The entire study will last about 24 months. Throughout the study, participants will be closely monitored for changes in the frequency of their countable motor seizures compared to baseline over up to 15 weeks. Researchers will collect data through seizure diaries maintained by participants or caregivers, clinical assessments, and safety evaluations. The study also tracks adherence to treatment and overall tolerability to better understand the impact of LP352 on seizure control and patient well-being.

The purpose of the study is to evaluate whether ibuzatrelvir is effective and safe in adults and adolescents with COVID-19 who do not need to be in the hospital but who are at high risk for progression to severe disease. Eligible participants will be randomly assigned (by chance) to receive ibuzatrelvir or matching placebo orally for 5 days. Co-administration of locally available standard of care is allowed. The total duration of the study is around 6 months.

Researchers are evaluating the effect of muvalaplin on reducing cardiovascular risk in adults with elevated lipoprotein(a) levels who either have atherosclerotic cardiovascular disease or are at risk for a heart attack or stroke. This Phase 3, randomized, double-blind, placebo-controlled study focuses on adults with high Lp(a) levels and prior or potential cardiovascular events. The study aims to assess the time to the first major adverse cardiovascular event over about 5.25 years. Participants will be randomly assigned to receive either muvalaplin or a placebo, both administered orally. The study includes individuals with Lp(a) levels of at least 175 nanomoles per liter who have had a prior cardiovascular event within 10 years or are at risk for a first event due to conditions such as coronary artery disease, carotid stenosis, peripheral artery disease, high coronary artery calcium score, reduced kidney function with diabetes, or other high-risk factors. The treatment period lasts through the study duration, with close monitoring. During the study, participants will be regularly evaluated to track the occurrence of major adverse cardiovascular events, including heart attacks and strokes. Safety assessments will monitor blood pressure, kidney function, and heart failure status among other health indicators. The primary outcome measures the time to the first major cardiovascular event from baseline up to the end of the study, which spans approximately 5.25 years.

Researchers are evaluating treatments for newly diagnosed ANCA-associated vasculitis, a serious disease involving inflammation of small to medium blood vessels. This phase 4 trial compares whether avacopan combined with short-term reduced-dose glucocorticoids and rituximab works as well as a longer 20-week reduced-dose glucocorticoid and rituximab treatment for achieving remission. The study also examines if avacopan lowers relapse rates compared to rituximab maintenance therapy and assesses the long-term safety of avacopan. Participants will be randomly assigned to one of two treatment groups. One group receives avacopan with short-term (up to 4 weeks) reduced-dose prednisolone and rituximab given at the start. The other group receives reduced-dose prednisolone for up to 20 weeks combined with rituximab administered at weeks 0, 26, 52, and 78. The study is open-label and will follow patients for up to 104 weeks to compare remission, relapse, and safety outcomes. Patients will be evaluated at multiple time points from baseline through week 104. Assessments include disease status (remission or relapse), disease activity scores, damage indexes, and adverse events. The main outcome is the proportion of patients achieving remission at 26 weeks. Researchers will monitor long-term safety and relapse rates over two years to better understand the benefits and risks of these treatment approaches.

Researchers are evaluating the effects of survodutide in adults aged 18 years and older who have a confirmed liver condition called non-alcoholic steatohepatitis (NASH) or metabolic-associated steatohepatitis (MASH). Eligible participants must have a body mass index (BMI) of 27 kg/m2 or higher, or at least 25 kg/m2 if they are Asian. The study excludes those with other chronic liver diseases or a history of significant alcohol use. The main goal is to see if survodutide can improve liver function and delay progression of liver damage over time. Participants are randomly assigned to receive either survodutide or a placebo, with twice the chance of receiving survodutide. Both treatments are given as weekly injections under the skin using a pre-filled syringe. Alongside treatment, all participants receive regular counseling to encourage healthy diet and exercise habits. The study lasts up to four and a half years, with frequent visits or remote video calls during the first year and five months, then quarterly visits thereafter. During the study, doctors monitor participants' health, including body weight and liver function using imaging tests at certain visits. Participants complete symptom questionnaires to help assess their condition. Researchers track outcomes such as survival, need for liver transplant, worsening liver disease, and liver-related complications. Safety and any side effects are closely watched throughout the study period to understand the treatment's impact.
