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 safety and effectiveness of two combined treatments, KarXT and KarX-EC, for adults aged 55 to 90 who experience agitation related to Alzheimer's Disease. This Phase 3, randomized, double-blind, placebo-controlled study aims to better understand how these treatments may help reduce agitation symptoms in this population while monitoring safety. Participants will receive either the active drugs Xanomeline/Trospium Chloride Capsule and Xanomeline Enteric Capsule or a placebo, taken at specified doses on designated days. The study is carefully designed to compare these treatments against placebo to evaluate their impact on agitation symptoms associated with Alzheimer's Disease. During the study, participants will be assessed using the Cohen-Mansfield Agitation Inventory-International Psychogeriatric Association (CMAI-IPA) total score to measure changes from baseline at Week 14. Caregivers will be involved to help monitor compliance and report participant status throughout the study. Safety and efficacy will be closely monitored during this 14-week period to gather detailed information about treatment outcomes.

Researchers are evaluating how well oral icotrokinra works, its safety, and how well patients tolerate it in adults and adolescents with moderately to severely active ulcerative colitis, a chronic condition where the colon lining becomes inflamed and develops ulcers. This is a Phase 3 study aimed at finding effective treatments for this condition using a rigorous comparison. Participants will receive either icotrokinra tablets or placebo tablets taken by mouth. The study includes an induction phase and a maintenance phase, with adults participating in a randomized, double-blind, placebo-controlled design, while adolescents join an open-label maintenance study. Throughout the study, researchers will monitor clinical remission rates at 12 weeks during induction and at 40 weeks during maintenance. Participants will undergo assessments including endoscopic evaluations and pregnancy tests for females of childbearing potential. Safety and tolerability will be closely observed, with the total study duration covering both induction and maintenance periods.

Researchers are conducting the X-TOLE3 Phase 3 clinical trial to evaluate the safety, tolerability, and effectiveness of XEN1101 as an additional treatment for adults with focal-onset seizures. The study focuses on measuring changes in seizure frequency when XEN1101 is added to existing antiseizure medications compared to placebo. Participants must have a confirmed diagnosis of focal epilepsy and have tried at least two antiseizure medications without achieving seizure freedom. About 360 participants will be randomly assigned in equal groups to receive either XEN1101 at 25 mg, 15 mg, or a placebo. The study includes up to 9.5 weeks of baseline observation to record seizure frequency, followed by 12 weeks of double-blind treatment where participants take the assigned capsules once daily with an evening meal. Those who complete this period may join a separate open-label extension to continue XEN1101 treatment, while others will enter an 8-week follow-up after treatment ends. During the study, participants will maintain accurate seizure diaries and continue stable doses of 1 to 3 antiseizure medications. Researchers will monitor seizure frequency changes from baseline through the 12-week treatment. Safety and tolerability will also be assessed throughout the trial. The total participation includes baseline, treatment, and follow-up periods to ensure thorough evaluation of the treatment's impact.

The primary purpose of the study is to assess how well amivantamab in combination with lazertinib or in combination with chemotherapy works (antitumor activity) in participants with epidermal growth factor receptor mutated (EGFRm) non-small cell lung cancer (NSCLC; that is one of the major types of lung cancer).

Researchers are evaluating the effectiveness of camizestrant compared to standard endocrine therapy in patients with early breast cancer that is estrogen receptor positive (ER+) and human epidermal growth factor receptor 2 negative (HER2-). These patients have an intermediate or high risk of cancer recurrence and have already completed local treatments such as surgery and possibly chemotherapy, alongside at least 2 years and up to 5 years of standard adjuvant endocrine therapy. The study is a Phase III, open-label trial designed to assess outcomes over a long term. Participants will be randomly assigned to receive either camizestrant, an oral selective estrogen receptor degrader, or one of several standard endocrine therapies including tamoxifen, anastrozole, letrozole, or exemestane, administered according to local approved guidelines. The treatment duration for both groups is planned to last 60 months. Eligible patients may have previously used CDK4/6 inhibitors, and the study will specifically include those with intermediate or high risk of recurrence as determined by clinical and biological markers. During the study, participants will be monitored for up to 10 years from the last patient's randomization to evaluate invasive breast cancer-free survival. Additional outcomes include invasive disease-free survival, distant relapse-free survival, overall survival, safety, and clinical outcome assessments. The study involves ongoing assessments of health status, treatment effects, and safety to determine the long-term benefits and risks of camizestrant compared to standard therapies.

Researchers are evaluating Risvutatug rezetecan (Ris-Rez), a new medicine that targets specific proteins called B7-H3 on cancer cells to reduce the cancer's ability to grow and spread. This study focuses on participants with relapsed extensive-stage small cell lung cancer (ES-SCLC) who have previously received platinum-based systemic therapy combined with a PD-(L)1 inhibitor. The trial aims to compare how well Ris-Rez works versus the standard treatment topotecan in shrinking tumors or making them disappear, and whether Ris-Rez helps participants live longer. The study also assesses the safety and tolerability of Ris-Rez compared to topotecan and gathers information on side effects of both treatments. Participants will be randomly assigned to receive either Ris-Rez, administered as a biological treatment, or topotecan, given as a drug treatment. The study is a phase 3, multicenter, randomized, open-label clinical trial. Both treatments will be provided according to the study protocol, and participants will be monitored carefully throughout the treatment period. During the study, participants will undergo assessments to monitor tumor response using RECIST 1.1 criteria and overall survival for up to approximately 113 weeks. Researchers will also evaluate participants' organ function, performance status, and side effects. Safety monitoring includes checking for cardiovascular health, infections, bleeding, and lung conditions. The study requires participants to provide informed consent and comply with study procedures and restrictions throughout their involvement.

Researchers are evaluating the effectiveness and safety of icotrokinra in adults with moderately to severely active Crohn's disease, a chronic condition causing severe inflammation in the intestinal tract. This Phase 2b/3 study aims to understand how well icotrokinra works compared to a placebo in improving symptoms and intestinal healing in this patient group. Participants will receive either icotrokinra or a matching placebo orally every day. The study includes both induction and maintenance phases where researchers assess clinical and endoscopic responses at specific time points, such as Week 12 and Week 40, to determine treatment effects over time. Throughout the study, participants will undergo various assessments including clinical evaluations, endoscopic exams, and safety monitoring. Researchers will measure outcomes like clinical response, clinical remission, and endoscopic healing at Weeks 12 and 40. The study involves regular monitoring to track the participants' health and treatment adherence over the duration of the trial.

Researchers are evaluating the safety and effectiveness of Ifinatamab Deruxtecan (I-DXd) compared to treatment chosen by physicians for adults with relapsed extensive-stage small cell lung cancer (ES-SCLC). The study aims to find out if I-DXd can improve the objective response rate, meaning the proportion of patients whose cancer shrinks or disappears, and extend overall survival time compared to other treatments. Secondary goals include assessing safety, patient-reported outcomes, immune response to I-DXd, B7-H3 protein levels, and how the drug is processed in the body. Participants will receive either I-DXd at a dose of 12 mg/kg given intravenously on the first day of each 21-day treatment cycle or one of the physician's choice treatments including Topotecan, Amrubicin, or Lurbinectedin, administered according to local standards of care. The study is randomized and open-label, meaning treatments are assigned by chance and both patients and doctors know which treatment is given. During the study, participants will be closely monitored with tumor assessments to evaluate response and detect disease progression, safety evaluations, and quality of life questionnaires. The main outcomes measured are the objective response rate assessed by a blinded independent review and overall survival time, tracked for up to approximately five years after randomization. Researchers will also monitor for any adverse effects and collect health economics data to understand the broader impact of treatments.

Researchers are evaluating zolbetuximab combined with pembrolizumab and chemotherapy in adults with locally advanced, unresectable, or metastatic stomach or gastroesophageal junction (GEJ) cancer. This study focuses on cancer cells that are HER2-negative but positive for the Claudin 18.2 protein and PD-L1, exploring how well zolbetuximab helps the immune system attack the tumor alongside immunotherapy and chemotherapy. The trial is a phase 3, randomized, double-blind study designed to compare the overall survival of participants receiving zolbetuximab with pembrolizumab and chemotherapy versus those receiving a placebo with pembrolizumab and chemotherapy. Participants receive study treatment in 6-week cycles, with zolbetuximab or placebo given by infusion every 2 or 3 weeks. Chemotherapy regimens include either CAPOX (capecitabine tablets and oxaliplatin infusion) or mFOLFOX6 (infusions of 5-fluorouracil, folinic acid, and oxaliplatin) administered on schedules matching the cycles. Pembrolizumab is infused every 3 or 6 weeks. Treatment continues until cancer worsens, is not tolerated, or another therapy is needed, with pembrolizumab given for up to 2 years. After initial cycles, some chemotherapy drugs are adjusted to only include oral capecitabine or certain infusions. During the study, participants visit the clinic for treatments, health checks, and scans to monitor cancer changes and side effects. Researchers also track medical problems related to the treatments and may collect tumor samples if cancer worsens. After stopping treatment, participants have follow-up visits and scans every 9 to 12 weeks, along with telephone check-ins every 3 months. The primary outcome measured is overall survival up to 72 months, with ongoing monitoring to evaluate safety and treatment effects.
