Researchers are evaluating the treatment of anemia in patients with chronic kidney disease CKD who are on hemodialysis. This Phase III, investigator-blinded, randomized, multicenter study compares two drugs, efepoetin alfa and darbepoetin alfa, to see how well they maintain hemoglobin levels in these patients. The study aims to maintain hemoglobin between 10.0 gdL and 12.0 gdL, which is important for managing anemia in CKD. Participants will be randomly assigned in a 21 ratio to receive either efepoetin alfa or darbepoetin alfa. Both drugs are given by intravenous injection, typically after dialysis sessions. Efepoetin alfa is administered weekly from Day 1 to Week 28, with possible interval changes to one or two weeks from Week 29 to Week 52 based on investigator judgment. The study consists of three periods screening up to 28 days, treatment about 52 weeks, and a 4-week follow-up with phone contacts up to Week 56 or the last visit. During the study, participants will undergo regular assessments including hemoglobin level monitoring to evaluate the mean change between Week 20 and Week 28. Safety and efficacy are closely observed, with dosages adjusted to maintain target hemoglobin levels. Follow-up will include phone contacts to monitor participants up to Week 56. The total participation duration is approximately one year, starting from screening through treatment and follow-up.

Researchers are evaluating the combination of baxdrostat and dapagliflozin in people with chronic kidney disease CKD and high blood pressure hypertension. This Phase III, double-blind, placebo-controlled study aims to assess whether this combination reduces the risk of serious kidney damage, heart failure events, or cardiovascular death compared to dapagliflozin alone. The study includes participants with CKD and hypertension who meet specific kidney function and blood pressure criteria. Participants who are not already taking SGLT2 inhibitors will first complete a 4-week dapagliflozin run-in period. Then, they will be randomly assigned to receive either baxdrostat plus dapagliflozin or a placebo plus dapagliflozin. Baxdrostat dosing may start low and be increased if needed. Study visits will occur at 2, 4, 8, 16, 34, and 52 weeks after randomization, and then approximately every four months until the study ends, which is based on the number of key kidney or heart-related events. Throughout the study, participants will have regular assessments including blood tests to monitor kidney function and potassium levels, blood pressure measurements, and evaluations of heart and kidney health. If participants stop the blinded study drug early, they will continue dapagliflozin if possible and remain in the study for ongoing visits and monitoring. The main outcome is whether the combination treatment reduces the risk of a 50% sustained decline in kidney function, kidney failure, heart failure events, or cardiovascular death over up to 37 months.

Researchers are studying the effectiveness and safety of lebrikizumab in people aged 12 and older who have chronic rhinosinusitis with nasal polyps and are treated with intranasal corticosteroids. This Phase 3 trial compares different dosing schedules of lebrikizumab with a placebo to find out how well it reduces symptoms such as nasal congestion and polyp size over about 18 months. Participants receive lebrikizumab or placebo as subcutaneous injections while continuing their regular intranasal corticosteroid therapy. Adolescents aged 12 to under 18 weighing at least 40 kg will receive open-label lebrikizumab every 2 or 4 weeks. The study includes two experimental lebrikizumab groups with different dosing intervals and a placebo group, all alongside background intranasal corticosteroids. During the study, participants will have regular assessments including symptom severity scores, nasal polyp size measured by endoscopy, sinus imaging, lung function tests, and questionnaires about nasal symptoms and quality of life. Researchers will monitor changes from baseline to week 24 primarily for nasal congestion and polyp scores. Safety and long-term effects will also be observed throughout the study duration of about 18 months.

Researchers are evaluating orforglipron to measure its effects on cardiovascular outcomes in adults aged 50 and older who have atherosclerotic cardiovascular disease ASCVD andor chronic kidney disease CKD. This phase 3 study aims to compare orforglipron with a placebo to better understand its impact on major cardiovascular events over about five years. Participants will be randomly assigned to receive either orforglipron orally along with standard care or a placebo orally along with standard care. The study is double-blinded, meaning neither participants nor researchers will know who receives the active drug or placebo during the trial period. During the study, participants will be followed for around five years, with researchers monitoring the time to the first major cardiovascular event and additional outcomes such as cardiovascular and kidney events, changes in kidney function measured by eGFR, and the onset of type 2 diabetes. The study includes regular assessments to track these outcomes and ensure participant safety throughout the long-term follow-up.

This research aims to evaluate the antiviral effects of S-337395 compared with a placebo in adults who are not hospitalized but have respiratory syncytial virus RSV infection and are at high risk of progressing to severe disease. Participants must start treatment within 72 hours of showing RSV symptoms. The study is a Phase 2b trial and involves adults with specific risk factors such as older age and chronic lung or cardiovascular disease. Participants will be randomly assigned to receive either a high dose or low dose of S-337395, or a matching placebo. The treatment is given orally twice daily for up to 5 days. The study is double-blind, meaning neither participants nor researchers know which treatment is being administered during the trial. Throughout the study, participants will be monitored closely with assessments including nasal swabs to measure RSV RNA levels at several time points up to day 6. Researchers will also track symptoms using questionnaires and record any side effects up to 28 days. Blood samples will be collected to measure drug levels, and safety will be monitored throughout the study, which runs until December 2026.

Researchers are evaluating the safety of an investigational varicella vaccine VNS Vaccine compared to an approved varicella vaccine called Varivax. This study focuses on healthy children aged 12 to 15 months who have not had chickenpox or received any varicella vaccine before. The goal is to understand how well the new vaccine is tolerated in this young population. Participants will receive one dose of either the investigational varicella vaccine or the marketed Varivax vaccine, both given by injection under the skin. Along with the varicella vaccine, each child will also receive one dose each of measles, mumps, and rubella MMR vaccine, hepatitis A vaccine, and a pneumococcal conjugate vaccine PCV, which may be PCV 13, Vaxneuvance, or PCV 20, depending on availability and national recommendations. All vaccines are given on the first day of the study. During the study, parents will record any side effects their child experiences, particularly those related to the injection site or systemic symptoms like fever, for up to 43 days. Researchers will monitor any adverse events, including serious and medically attended events, for up to 181 days after vaccination. This helps assess the safety and tolerability of the investigational vaccine over a period of about six months.

Researchers are studying the use of ruxolitinib cream in children aged 6 to under 12 years who have nonsegmental vitiligo. The study aims to evaluate how well and how safely the cream works for treating this condition, which causes loss of skin color. This is a Phase 3 clinical trial focused on treatment effects in this pediatric population. Participants are assigned to one of three groups receiving either ruxolitinib cream at 0.75% or 1.5%, or a matching vehicle placebo cream. Each cream is applied topically as a thin film twice daily to the affected skin areas as defined in the study protocol. The treatment period lasts up to 24 weeks, during which changes in skin pigmentation are monitored. Throughout the study, participants undergo regular assessments including evaluations of vitiligo improvement on the face and body using the Vitiligo Area Scoring Index and other scales. Safety is monitored by tracking adverse events and blood levels of the drug at multiple timepoints up to 52 weeks. Quality of life and psychosocial effects are also measured. The total study duration includes treatment and follow-up visits to assess long-term outcomes and safety.

This research aims to learn about the safety and effects of the study medicine PF-07328948 for adults with heart failure. The study evaluates whether PF-07328948 is safe and effective compared to a placebo in people who already take standard heart failure medicines including SGLT2 inhibitors. It is a phase 2 randomized, double-blind, placebo-controlled trial sponsored by Pfizer. Participants will take either placebo tablets or one of three doses of PF-07328948 tablets once daily by mouth for 36 weeks. The study includes four groups placebo, low dose, medium dose, and high dose of PF-07328948. Treatment lasts 36 weeks, followed by monitoring and assessments. Participants will be involved for about 48 weeks with 15 visits to the study clinic, of which 5 may be performed at home by phone and 10 in person. Researchers will assess clinical events, 6-minute walk test distance, and heart failure symptom scores at baseline and week 36. Safety will be monitored through adverse event reporting up to week 40. Various questionnaires and physical tests will track health status and treatment effects throughout the study.

Researchers are evaluating the combined use of vicadrostat and empagliflozin in adults with chronic heart failure who have a reduced left ventricular ejection fraction LVEF below 40%. Participants must have had chronic heart failure diagnosed at least three months before starting the study. The trial aims to find out if this combination helps people with symptomatic heart failure classified as New York Heart Association classes II to IV. Participants are randomly assigned to one of two groups, with an equal chance of receiving either vicadrostat plus empagliflozin tablets or placebo plus empagliflozin tablets. The study medicines are taken once daily for approximately six months up to about 3.5 years. During this time, participants may continue their usual heart failure treatments, excluding certain medications. The trial includes a double-blind design, meaning neither participants nor study staff know who receives the active drug or placebo. Throughout the study, participants visit the study site regularly, with the number of visits depending on how long they stay enrolled. Some visits may occur by phone. They answer questions about their well-being, and doctors monitor health status, record any heart failure worsening, hospitalizations, or deaths. The main outcome is the time until cardiovascular death, heart failure hospitalization, or urgent heart failure visit, which is compared between groups. Safety and side effects are also closely followed during the trial.

Researchers are evaluating ziltivekimab, a new medicine not yet approved anywhere, to see if it can help people who were hospitalized due to a heart attack. The study aims to find out if ziltivekimab can reduce the development of heart disease and prevent future heart attacks or strokes. This is a Phase 3 clinical trial comparing ziltivekimab to a placebo in patients with acute myocardial infarction. Participants will receive an initial loading dose of ziltivekimab or matching placebo by injection under the skin as soon as possible after an invasive heart procedure, within 36 hours for STEMI or 48 hours for NSTEMI patients. After the loading dose, they will get monthly injections of the same study medicine for up to two years, in addition to their standard care. During the study, participants will be monitored for major cardiovascular events such as heart attack, stroke, and cardiovascular death. Researchers will also track other heart-related outcomes and safety measures over a period of up to 25 months. The study involves regular visits for injections, assessments, and laboratory tests to evaluate the medicines effects and patient health throughout the trial.
