Researchers are investigating whether tirzepatide can improve ovarian dysfunction in premenopausal women with polycystic ovary syndrome PCOS who are overweight or have obesity. This phase IV, multi-center, randomized, double-blind, placebo-controlled trial aims to show that tirzepatide at the maximum tolerated dose is better than placebo for improving menstrual irregularity related to PCOS. The study is conducted at five sites in Germany and focuses on women aged 18 to 45 years with PCOS defined by specific criteria.

Researchers are evaluating treatments for germinal center B-cell-like diffuse large B-cell lymphoma GCB DLBCL, a fast-growing blood cancer affecting immature B-cells. The study compares two treatment combinations to see if more people respond to zilovertamab vedotin MK-2140 plus R-CHP versus polatuzumab vedotin plus R-CHP. This Phase 2 trial aims to assess the effectiveness and safety of these regimens in participants with newly diagnosed GCB DLBCL. Participants receive either zilovertamab vedotin along with rituximab, cyclophosphamide, doxorubicin, and prednisone R-CHP, or polatuzumab vedotin combined with R-CHP. Treatments are given by intravenous infusion on Day 1 of each 3-week cycle for up to 6 cycles, approximately 4 months, with prednisone or prednisolone taken orally for 5 days of each cycle. For participants with high-risk DLBCL, up to 2 additional cycles of rituximab or biosimilar are given. During the study, participants are monitored for response to treatment using Lugano Response Criteria, with follow-up lasting up to about 31 months for the primary outcome. Secondary outcomes include progression-free survival, overall survival, event-free survival, duration of complete response, adverse events, and quality of life assessments. Safety and health status are regularly checked through exams, lab tests, and questionnaires over several years, with total study participation extending up to 7 years.

Researchers are evaluating the safety, effectiveness, and how the body processes and responds to NXT007 prophylaxis compared with emicizumab prophylaxis in people aged 12 years and older who have severe or moderate congenital hemophilia A without factor VIII FVIII inhibitors, or any severity of hemophilia A with FVIII inhibitors. This phase 3, randomized, open-label study aims to compare these treatments to better understand their impact on bleeding rates and treatment burden. Participants will be randomly assigned to one of two main treatment groups. One group will receive NXT007 prophylaxis administered subcutaneously using an integrated drug-device combination product. The other group will receive emicizumab prophylaxis via subcutaneous injections, starting with weekly loading doses for 4 weeks, then maintenance dosing at various intervals depending on prior treatment status. After the main treatment period, participants from both arms can continue or switch to NXT007 in an open-label extension phase. Throughout the study, participants will be closely monitored with regular assessments, including measuring annualized bleed rates for different types of bleeds, treatment burden questionnaires, and safety evaluations such as adverse event monitoring and laboratory tests. These evaluations will continue throughout approximately 3.5 years of study participation to provide comprehensive data on treatment effects and safety.

Researchers are evaluating the effectiveness, safety, and how the body processes and responds to NXT007 prophylaxis compared to Factor VIII FVIII prophylaxis in people aged 12 years and older with severe or moderate congenital hemophilia A who do not have inhibitors. This phase III study focuses on participants who have previously been treated with FVIII prophylaxis. The goal is to understand how NXT007 performs against the current standard treatment for this condition. Participants will be randomly assigned to receive either NXT007 prophylaxis, given as a subcutaneous injection with an integrated drug-device combination product, or standard Factor VIII prophylaxis according to local dosing and frequency guidelines. After the main six-month treatment period, those receiving NXT007 may continue this treatment in an open-label extension, and those initially on FVIII prophylaxis may switch to NXT007 during this extension phase. During the study, participants will be closely monitored through various assessments, including tracking the annualized bleed rate ABR for treated bleeds over six months, questionnaires evaluating treatment burden and impact on social and recreational activities, and safety evaluations such as adverse events, injection-site reactions, and antibody development against NXT007. The study will continue follow-up for approximately 3.5 years to gather comprehensive data on treatment effects and safety.

Researchers are investigating treatments for oligodendrogliomas, a type of brain tumor classified by specific genetic markers including mutations in isocitrate dehydrogenase IDH and co-deletion of chromosomes 1p19q. This trial focuses on adults with newly diagnosed grade 2 or 3 gliomas, aiming to improve survival without loss of brain function, cognition, or quality of life. The study compares two treatment approaches to determine the best timing and combination of chemotherapy and radiotherapy. Participants are randomly assigned to receive either standard chemoradiation with procarbazine, CCNU lomustine, and vincristine PCV combined with radiotherapy, or an experimental approach starting with chemotherapy using lomustine and temozolomide CETEG followed by radiotherapy and PCV at tumor progression. Radiotherapy is delivered over about 5 to 6 weeks, with doses adjusted for tumor grade. Chemotherapy cycles last 6 weeks and include specified doses of oral and intravenous drugs. During the study, participants undergo regular magnetic resonance imaging MRI scans every three months, neurological assessments, quality of life questionnaires, and cognitive testing annually. The main outcome measured is qualified overall survival, which tracks survival without significant cognitive or functional decline. The study lasts up to 10 years, with ongoing monitoring of tumor progression, treatment response, and patient wellbeing. Safety and side effects are carefully assessed throughout the trial.

This clinical trial evaluates the efficacy and safety of elsunersen in children with early-onset SCN2A Developmental and Epileptic Encephalopathy, a condition characterized by seizures beginning before 3 months of age. The study focuses on pediatric participants confirmed to have a gain of function SCN2A genetic variant, aiming to understand how elsunersen impacts seizure frequency and related symptoms. The trial is sponsored by Praxis Precision Medicines and is conducted at multiple centers. Participants receive intrathecal doses of elsunersen every 4 weeks for a total of 24 weeks. Two dosing levels, 1mg and 0.5mg, are being studied in an open-label design across three cohorts. All participants receive the study drug without a placebo comparison, and treatment effects on seizures and other clinical assessments are monitored throughout the treatment period. During the 24-week treatment, participants undergo regular evaluations to assess seizure frequency, clinical global impression of severity and improvement, and sleep quality among other outcomes. Safety and tolerability are also closely monitored. The trial includes baseline observation periods and follow-up assessments to track changes over time, providing a comprehensive view of elsunersens impact in this pediatric population.

Researchers are evaluating the efficacy and safety of trontinemab in people with early symptomatic Alzheimers disease, ranging from mild cognitive impairment to mild dementia due to Alzheimers. This Phase III trial aims to understand how trontinemab affects cognitive decline and disease progression in this population. Participants are randomly assigned to receive either intravenous trontinemab or a placebo in a parallel-group design. Treatment is administered by IV infusion, and the effects are compared over a period of 72 weeks. The study includes comprehensive safety and efficacy assessments throughout this period. During the 72 weeks of the study, participants will undergo various evaluations including cognitive tests such as the Clinical Dementia Rating-Sum of Boxes CDR-SB, Alzheimers Disease Assessment Scales, brain imaging with PET and MRI scans, and biomarker measurements in cerebrospinal fluid and blood. Safety monitoring includes tracking adverse events, infusion reactions, and antibody development. The study requires participants to have a study partner and to complete all study procedures over this time.

Researchers are comparing two psychotherapy programs, the Cognitive Behavioral Analysis System of Psychotherapy CBASP and Behavioral Activation BA, in adults with persistent depressive disorder PDD who have not responded well to previous treatments. This study focuses on hospitalized patients with treatment-resistant depression and aims to evaluate which therapy is more effective in reducing depressive symptoms over 16 weeks. The study also explores factors that affect treatment response and the long-term effects of these therapies. Participants will receive either CBASP or BA treatment during a 10-week acute phase consisting of inpatient or dayclinic therapy followed by a 6-week outpatient continuation phase with group therapy. Both therapies include individual and group sessions, nurse contacts, and exercise therapy during inpatient treatment. All patients will also receive optimized antidepressant medication according to standard guidelines, with adjustments if needed based on response. During the study, participants will undergo regular assessments using various depression rating scales, symptom inventories, and quality of life questionnaires from baseline through 64 weeks after treatment start. Researchers will monitor responses, remission, relapse rates, and cost-effectiveness of the treatments. The total study duration includes acute treatment, continuation therapy, and long-term follow-up to evaluate sustained outcomes and health economic impacts.

Researchers are evaluating whether using an automated Carbon Dioxide CO2 injection system during infrainguinal peripheral vascular interventions PVI can reduce major adverse kidney events within 90 days in patients at moderately increased risk for contrast-associated acute kidney injury CA-AKI. This Phase 3 randomized controlled trial compares a CO2-based contrast medium sparing strategy to the standard use of iodinated contrast media in patients with peripheral vascular and kidney diseases. Participants are randomly assigned to one of two groups. The intervention group receives PVI using an automated CO2 injection system as the primary contrast agent, with iodinated contrast media available as a backup if image quality is insufficient or if the patient cannot tolerate CO2 angiography. The control group undergoes routine PVI using iodinated contrast media according to local standards, avoiding high-osmolar contrast agents. All patients are followed for up to 12 months after their procedure. During the study, participants undergo the planned PVI procedure with either contrast method. Researchers carefully record the amount and reasons for any iodinated contrast media used in the CO2 group. Patients are monitored for kidney-related outcomes, focusing on major adverse kidney events up to 90 days after the intervention. The trial includes ongoing follow-up assessments to evaluate safety and effectiveness over one year.

Researchers are evaluating zorevunersen, an investigational antisense oligonucleotide drug, in children with Dravet syndrome, a rare and severe form of epilepsy. This Phase 3, global, multicenter, randomized, double-blind, sham-controlled study aims to assess the efficacy, safety, and tolerability of zorevunersen by measuring changes in major motor seizure frequency and other important aspects such as behavior, cognition, clinical status, and quality of life. Participants will be randomly assigned to receive either zorevunersen or a sham procedure during Treatment Period 1, which lasts about 52 weeks. Zorevunersen is given by intrathecal injection at specific doses and intervals throughout this period. After Treatment Period 1, all eligible patients enter Treatment Period 2, where everyone receives zorevunersen for additional dosing over several months. Patients who complete the study may have the chance to join an open-label extension to continue receiving the drug. During the study, participants will undergo regular assessments including seizure monitoring, behavioral and cognitive evaluations, and health-related quality of life measurements. The primary outcome is the change in major motor seizure frequency at Week 28, with secondary outcomes assessed at Week 52. Safety and tolerability are also closely monitored. Overall participation lasts through both treatment periods and possible extension, with detailed follow-up to evaluate the drugs potential for disease modification.
