Researchers are evaluating the long-term safety of subcutaneous guselkumab injections in children with moderately to severely active ulcerative colitis, Crohns disease, or juvenile psoriatic arthritis. This Phase 3 study focuses on pediatric participants who have previously been treated with guselkumab and will continue therapy in this extension study to monitor safety over an extended period. Participants who completed dosing in one of three primary pediatric guselkumab studies and are deemed by their investigator to benefit from continued treatment will join this long-term extension. Guselkumab is administered as a subcutaneous injection either every 8 weeks or every 4 weeks, depending on prior study assignment and clinical status. Some participants may switch dosing frequency once during the extension before unblinding, after which dosing aligns with their original regimen. Dose adjustments are restricted based on the primary study they came from. During the study, participants will receive guselkumab injections regularly and be monitored for treatment-emergent adverse events for up to nearly seven years. Researchers will assess safety outcomes through ongoing clinical evaluations over this time. Parents or legal representatives provide consent for children to participate, and children capable of understanding the study will give assent. The total participation duration may extend up to six years and nine months, allowing long-term safety data collection.

Researchers are evaluating DB-OTO, an investigational gene therapy, for children, infants, adolescents, and adults who have severe to profound hearing loss caused by mutations in the otoferlin gene. This study aims to learn about the safety of DB-OTO, how well it is tolerated without ongoing discomfort, and how effective it is in improving hearing abilities. Participants will receive DB-OTO through one of several dosing approaches including unilateral intracochlear injection, bilateral intracochlear injection based on safety and efficacy data from an initial phase, or either unilateral or bilateral dosing. The trial is open-label and includes sequential cohorts to evaluate safety, tolerability, and efficacy. The study consists of different parts where dosing and monitoring are tailored accordingly. During the study, participants will undergo various assessments to measure hearing sensitivity using Pure Tone Audiometry and Auditory Brainstem Response tests, as well as speech perception and auditory skill evaluations. Safety will be monitored by tracking treatment-emergent adverse events up to week 104. Participants and their guardians will be closely followed for over two years to evaluate hearing improvements and any changes in speech abilities or safety outcomes.

Researchers are evaluating the efficacy and safety of talquetamab, a drug given by injection, in adults with relapsed or refractory multiple myeloma who have received at least three prior treatments. This Phase 2 study focuses on participants who may or may not have been exposed to T cell redirection therapies. The goal is to understand how well talquetamab works and its safety profile in this patient group. Participants are divided into five cohorts based on their previous treatments and exposure to T cell redirection therapies. They will receive talquetamab by subcutaneous injection at doses selected from earlier parts of the study. Treatment continues until disease progression, and participants will move into open-label and long-term extension phases to keep receiving the study drug as approved by the sponsor. During the trial, participants will have regular assessments including laboratory tests, safety evaluations, and quality of life questionnaires. Researchers will measure outcomes such as overall response rate, duration of response, progression-free survival, and safety events for up to nearly three years. Participants health and treatment effects will be closely monitored throughout this period.

Researchers are evaluating TRK-950 in patients with advanced solid tumors, including melanoma, who have limited or no standard treatment options. This open-label phase III study aims to assess the safety, tolerability, pharmacokinetics, and immune response to TRK-950 alone or in combination with Nivolumab. The study includes patients who have advanced or metastatic tumors refractory or intolerant to existing therapies or those eligible for Nivolumab treatment. The study is divided into three parts. Part 1 involves two dose levels of TRK-950 given intravenously weekly on days 1, 8, 15, and 22 of a 28-day cycle. Part 2 evaluates TRK-950 combined with Nivolumab, where Nivolumab is administered intravenously at 240 mg every two weeks on days 1 and 15, and TRK-950 is given intravenously weekly or bi-weekly depending on the cohort. Part 3 focuses on patients with advanced unresectable or metastatic melanoma who previously received chemotherapy with dacarbazine these patients receive TRK-950 intravenously weekly on days 1, 8, 15, and 22 of a 28-day cycle. Participants will undergo safety monitoring including assessments of dose-limiting toxicities, adverse events, and immune reactions over approximately one year. Researchers will also measure drug levels, survival outcomes, tumor responses, and disease progression. Treatment is given in cycles of 28 days, and the study tracks participants throughout treatment and follow-up until study completion or as long as safety and efficacy data are collected.

Researchers are evaluating the efficacy and safety of KarXT in adult Japanese participants who are acutely psychotic with schizophrenia. This Phase 3 study focuses on adults aged 18 to 65 years who meet specific criteria based on psychiatric evaluations and symptom severity scores. The trial aims to understand how KarXT affects schizophrenia symptoms compared to a placebo over a 5-week period, followed by a longer open-label extension. Participants are randomly assigned to receive either KarXT or a placebo during a 5-week double-blind treatment phase. Following this, they may enter a 52-week open-label extension where all participants receive KarXT. The study includes regular dosing on specified days, with careful monitoring throughout both phases. During their participation, individuals undergo assessments of symptom changes using scales like the Positive and Negative Syndrome Scale PANSS and Clinical Global Impressions-Severity CGI-S. Safety is closely monitored through reports of adverse events, physical exams, laboratory tests, heart rate and blood pressure measurements, and other evaluations. The total study duration can last over a year, allowing for detailed observation of treatment effects and safety over time.

Researchers are evaluating the effects of a medicine called BI 1815368 in adults aged 18 and older who have a specific eye condition known as centre-involved diabetic macular edema CI-DME. This condition affects vision, and the study aims to find out if BI 1815368 can improve sight and to determine the best dose. The trial is a phase 2, randomized, double-masked, placebo-controlled study designed to assess efficacy, safety, and tolerability. The study has two parts. In the first part, participants are randomly assigned to one of two groups one receiving BI 1815368 tablets and the other receiving placebo tablets that look identical but contain no medicine. In the second part, participants are randomly assigned to one of four groups three groups receive different daily doses of BI 1815368, and one group receives placebo. All participants take the tablets twice daily for about 11 months. Participants stay in the study for about one year, during which they visit the study site 16 times. At these visits, doctors check vision, document any health problems, and take detailed eye pictures. Researchers compare changes over time between the groups to evaluate if the treatment affects vision. The main outcome measured is whether participants gain at least 10 Early Treatment Diabetic Retinopathy Study ETDRS letters in vision at Week 48 compared to baseline.

Researchers are evaluating the medicine BI 3000202 for adults with systemic lupus erythematosus SLE, a condition involving immune system problems. The study is a phase 2 trial that tests different doses of BI 3000202 to find the best dose for people with moderate to severe SLE. Participants are randomly assigned to one of five groups, including four groups receiving different doses of the medicine and one group receiving a placebo, which looks like the medicine but has no active drug. Participants take their assigned tablets daily for one year while continuing their usual SLE treatments. The study groups include four different dose levels of BI 3000202 and a placebo group. During the study, participants regularly visit the study site for check-ups and monitoring. This careful schedule helps researchers watch for any effects or side effects of the treatment. Throughout the study, doctors assess participants health, monitor any unwanted effects, and compare outcomes between groups. The main measurement is whether participants achieve a response on the Systemic Lupus Erythematosus Responder Index SRI-4 at week 32. Additional measurements include responses at week 52 and disease activity scores. Participants stay involved for a bit longer than one year, with regular visits to the study site for health checks and to ensure their well-being.

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 whether the combination of vicadrostat BI 690517 and empagliflozin helps adults with heart failure who have symptoms and a left ventricular ejection fraction LVEF of 40% or more. This phase III study is designed to compare the effects of vicadrostatempagliflozin tablets versus placeboempagliflozin tablets on heart failure outcomes. The study aims to understand if this combined treatment improves health and reduces heart-related events. Participants are randomly assigned to one of two groups one group takes vicadrostat plus empagliflozin tablets once a day, and the other takes placebo plus empagliflozin tablets once a day. The study has no fixed duration and continues as long as participants benefit and tolerate the treatment. Throughout the study, participants visit their doctors regularly for health checks, and study staff may also contact them by phone to monitor well-being and any side effects. During the study, researchers monitor participants health through regular doctor visits and phone contacts. They collect data on heart-related events such as cardiovascular death, hospitalizations for heart failure, and urgent visits for heart failure over up to 42 months. Participants also answer questions about their symptoms and well-being. The study carefully tracks safety and treatment tolerance while gathering information to determine if the combined treatment helps people with heart failure.

Researchers are evaluating sodium zirconium cyclosilicate SZC to treat hyperkalaemia in children under 18 years old. This Phase 3, international, open-label study aims to assess the effectiveness, safety, and tolerability of SZC. The study enrolls about 140 children from multiple countries, starting with age groups 6 to under 12 years and 12 to under 18 years. Later, younger age groups may be included based on data reviews. The goal is to see how well SZC controls potassium levels in children with this condition. The study includes three treatment phases Correction Phase CP, Maintenance Phase MP, and Long-Term Maintenance Phase LTMP. In the CP, participants receive fixed doses of SZC orally three times daily for up to 3 days until potassium levels normalize. Doses are adjusted based on body weight and age groups, with possible dose increases after safety reviews. Those who achieve normal potassium enter the 28-day MP with once daily SZC, where doses can be adjusted to maintain potassium levels. Participants may continue in the LTMP using the same dosing approach with monthly visits. Participants undergo regular monitoring including blood tests, urine tests, and ECGs to assess potassium levels, electrolytes, and heart rhythm. Researchers track safety, tolerability, potassium control, and other biochemical changes throughout the phases. The study lasts about 28 weeks, including treatment and a safety follow-up visit one week after the last dose. Data collected will help evaluate SZCs role in managing hyperkalaemia in children.
