Researchers are evaluating the safety and effectiveness of three different dose regimens of MORF-057, a small molecule drug, in adults with moderately to severely active Crohns disease CD. This Phase 2, randomized, double-blind, placebo-controlled, multicenter study aims to compare these doses with a matching placebo during an induction treatment period. The study includes adult participants who have active symptoms of CD and have not adequately responded to other treatments. Participants will first undergo a 14-week induction period where they receive either one of the three blinded MORF-057 dose regimens or a matching placebo, all taken orally. Following this, all participants enter a 38-week maintenance period receiving open-label MORF-057. Those who complete this 52-week treatment phase may have the chance to continue treatment for an additional 52 weeks during a long-term extension. MORF-057 is designed to selectively inhibit integrin 47. During the study, participants will have their disease activity monitored using endoscopic assessments and clinical symptom scores, such as the Simple Endoscopic Score for Crohns Disease SES-CD and the Crohns Disease Activity Index CDAI. Researchers will assess the proportion of participants showing endoscopic response and clinical remission at Week 14. Safety and adherence will be closely followed throughout the treatment and extension phases. The entire study spans up to 6 years, allowing for long-term evaluation.

Researchers are studying the impact and burden of three skin conditions moderate or severe alopecia areata, non-segmental vitiligo, and moderate to severe hidradenitis suppurativa. The study includes adolescents and adults and aims to understand how these conditions affect quality of life and daily functioning in a large global population. This is an observational study where participants with each condition will have a single visit for data collection following routine clinical practice. No experimental treatments are given instead, the study gathers information during this one visit to assess disease characteristics and impact. During the visit, participants will complete questionnaires and clinical assessments specific to their condition. These include tools measuring symptom impact, hair loss severity, skin depigmentation, and quality of life related to each disease. This helps researchers better understand the real-world burden of these conditions. Participation involves only this one visit, with no long-term follow-up or additional procedures.

Researchers are evaluating intismeran autogene combined with pembrolizumab compared to placebo plus pembrolizumab as an additional treatment after surgery for participants with certain stages of non-small cell lung cancer NSCLC. The study focuses on participants with margin-negative, completely resected Stage II, IIIA, or IIIB with nodal involvement NSCLC. The main question is whether the combination including intismeran autogene improves disease-free survival compared to pembrolizumab with placebo. Participants are randomly assigned to two groups. One group receives 1 mg of intismeran autogene by intramuscular injection every 3 weeks for nine doses plus 400 mg of pembrolizumab by intravenous infusion every 6 weeks for up to nine doses. The other group receives a placebo injection on the same schedule plus pembrolizumab on the same infusion schedule. Treatment continues until disease recurrence, unacceptable side effects, or approximately one year, whichever comes first. During the study, participants are monitored through regular assessments up to about 78 months for disease-free survival and up to 12 years for overall survival and other health outcomes. Quality of life questionnaires and adverse event monitoring are conducted at baseline and throughout the study. The research team tracks lung cancer-specific survival and distant metastasis-free survival, as well as changes in symptoms like coughing and chest pain. Safety is closely observed throughout treatment and follow-up periods.

Researchers are evaluating the safety of maribavir in adults who have severe chronic kidney disease CKD or end-stage renal disease ESRD, including those on dialysis, and who have a refractory cytomegalovirus CMV infection after transplantation. This observational study collects already existing data from participants medical records without changing their standard medical care or treatment. The study includes adults aged 18 years or older who have undergone solid organ or stem cell transplantation and have been treated with maribavir for refractory CMV infection. Data will be collected from the start of maribavir treatment through up to seven days after the last dose or until death or end of available data, whichever comes first. Participants include those with severe CKD or ESRD, including those on peritoneal or hemodialysis. Participants medical records will be reviewed to monitor any adverse events from maribavir treatment during the study period, which can last up to four years. The main measurement is the number of participants experiencing adverse events, including those of special interest. This review will not affect participants usual care, and no new treatments or interventions will be given as part of this study.

Researchers are evaluating the efficacy and safety of opevesostat combined with daily corticosteroids compared to alternative treatments abiraterone acetate or enzalutamide in participants with metastatic castration-resistant prostate cancer mCRPC who have previously been treated with one next-generation hormonal agent NHA. The study aims to determine if opevesostat offers better control of disease progression assessed by radiographic progression-free survival, including participants with and without androgen receptor ligand binding domain mutations. Overall survival has also been included as a secondary outcome measure. Participants are randomly assigned to one of two groups. One group receives opevesostat 5 mg orally twice daily, plus dexamethasone 1.5 mg and fludrocortisone acetate 0.1 mg orally once daily, continuing until disease progression. Hydrocortisone is available as a rescue medication if needed. The other group receives either abiraterone 1000 mg once daily with prednisone 5 mg twice daily or enzalutamide 160 mg once daily, also until disease progression. This open-label, phase 3 study compares these two treatment approaches in a parallel design. During the study, participants undergo regular assessments including imaging scans to measure disease progression, safety monitoring, and evaluations of overall survival and quality of life. Researchers track radiographic progression-free survival for up to 52 months and secondary outcomes such as overall survival, time to new treatments, pain progression, and prostate-specific antigen PSA responses for up to approximately 82 months. Participants are closely monitored for adverse events and treatment tolerability throughout the study duration, which spans several years.

Psoriatic arthritis PsA is a chronic inflammatory condition that affects the joints and skin in people with psoriasis. This study aims to evaluate how well zasocitinib TAK-279 works in adults with active PsA who have not previously been treated with biologic disease-modifying antirheumatic drugs. The trial is a Phase 3, randomized, double-blind study comparing zasocitinib with an active comparator and placebo. Participants will be assigned to one of four groups zasocitinib Dose A once daily, zasocitinib Dose B once daily, an active comparator capsule twice daily, or placebo once daily for 16 weeks followed by switching to zasocitinib Dose A or B up to 52 weeks. Treatments are taken orally as tablets or capsules over a period of up to 60 weeks. During the study, participants will undergo regular assessments including joint counts, skin evaluations, and various disease activity measurements such as ACR20 and PASI-75 responses. Researchers will monitor changes from baseline in functional and quality of life scores, as well as safety and tolerability. Participants will be involved in visits throughout the treatment period to evaluate the effects and collect data on the disease and treatment responses.

Researchers are evaluating the immune response and safety of GlaxoSmithKlines investigational chickenpox vaccine and a marketed measles, mumps, and rubella MMR vaccine when given to healthy children aged 12 to 15 months. The study compares these vaccines administered by muscle injection to Mercks chickenpox vaccine given just under the skin. It also assesses the immune response and safety when the GSK vaccines are given together with other routine childhood vaccines. Participants are randomly assigned to receive either the candidate varicella vaccine intramuscularly along with MMR, hepatitis A virus HAV vaccine, and a pneumococcal conjugate vaccine PCV, or the marketed varicella vaccine subcutaneously with the same additional vaccines. The PCV given may be PCV 13, Vaxneuvance, or PCV 20 depending on availability and national recommendations. All vaccines are given on Day 1. Throughout the study, children are monitored for immune responses by measuring antibody levels against varicella zoster virus and MMR antigens at Day 43. Safety is evaluated by tracking any local and systemic reactions in the days following vaccination, as well as any adverse events up to six months after the dose. The study aims to understand both the immune response and safety profile over this period in healthy young children receiving these vaccines.

Researchers are evaluating the consistency of immune responses to three different batches of an investigational chickenpox vaccine called VNS vaccine in healthy children aged 12 to 15 months who have not had chickenpox or received a chickenpox vaccine before. The study also compares the safety and immune response of the VNS vaccine to an approved chickenpox vaccine known as Varivax. This Phase 3a study is sponsored by GlaxoSmithKline and aims to better understand the immune protection provided by these vaccines. Participants are randomly assigned to receive one dose of either one of the three investigational VNS vaccine lots or one of two lots of the marketed Varivax vaccine. Along with the chickenpox vaccine, they also receive one dose each of measles, mumps, and rubella MMR vaccine, hepatitis A vaccine HAV, and a pneumococcal conjugate vaccine PCV which could be PCV 13, Vaxneuvance, or PCV 20 depending on availability and country recommendations. All vaccines are given on Day 1 of the study. During the study, researchers monitor the participants immune responses by measuring antibodies against varicella zoster virus VZV and other vaccine components at Day 43. They also track safety by recording any side effects or adverse events from Day 1 to Day 181. The study includes diary reports by parents and regular clinical evaluations to assess immune response and safety outcomes. Participation involves a single vaccination visit and follow-up assessments over approximately six months.

This trial investigates the treatment of adults with Chronic Inflammatory Demyelinating Polyneuropathy CIDP. It compares the effects of empasiprubart and intravenous immunoglobulin IVIg to evaluate which treatment may better reduce symptoms and improve function in people with CIDP. The study is a Phase 3, randomized, double-blind trial designed to assess both efficacy and safety of these treatments over an extended period. Participants are randomly assigned in Part A to receive either empasiprubart with a placebo resembling IVIg or IVIg with a placebo resembling empasiprubart for 24 weeks 6 months. After Part A, all participants enter Part B, where they receive empasiprubart for an additional 96 weeks 24 months. During Part B, those previously receiving empasiprubart continue with it, and those initially on IVIg switch to empasiprubart. Treatments are administered by intravenous infusion using a double-dummy design to maintain blinding. Throughout the study, participants undergo regular assessments of their disability, strength, grip, and quality of life using various scales such as aINCAT, I-RODS, MRC-SS, and others. Safety is monitored by tracking adverse events and antibody formation against empasiprubart. The primary outcome is the reduction of at least one point in the aINCAT score at week 24. Total participation lasts up to 120 weeks, including both treatment periods, with ongoing evaluations to understand the long-term effects of empasiprubart.

Researchers are evaluating the efficacy and safety of remibrutinib in patients with secondary progressive multiple sclerosis SPMS. This is a Phase III, randomized, double-blind, placebo-controlled, multi-center study involving approximately 1275 participants. The study aims to provide important data on remibrutinibs effect on disability progression in SPMS and includes both a Core Part and an Extension Part for further assessment. Participants are randomly assigned to receive either remibrutinib or a matching placebo as oral film-coated tablets during the Core Part. The Core Part includes double-blind treatment, followed by an Extension Part where all participants receive open-label remibrutinib tablets. Treatment is taken orally, and the study is event-driven, continuing until required endpoints are met. During the study, participants undergo regular assessments of disability progression using the Expanded Disability Status Scale EDSS, Timed 25-Foot Walk, 9-Hole Peg Test, and Symbol Digit Modalities Test, among others. Brain imaging and safety monitoring for adverse events are performed throughout up to approximately five years. Researchers track changes in brain lesions and atrophy, and follow participants for safety and treatment effects over time.
