Researchers are evaluating two different methods of pacing the heart in patients with slow heart rates (bradycardia). This multi-center randomized controlled trial, called PROTECT-HF, aims to compare the standard right ventricular pacing approach with a newer physiological pacing technique, which includes His bundle and left bundle area pacing. The study will enroll 2600 patients to assess differences in outcomes related to heart function and survival. Participants will be randomly assigned to receive either right ventricular pacing or physiological pacing through pacemaker implantation. The physiological pacing method may involve His bundle pacing or left bundle pacing, with biventricular pacing used if these are not possible. Both treatments will be performed at participating centers, with patients and outcome assessors blinded to the treatment allocation. A subgroup of 500 patients will also take part in an optional echocardiographic sub-study to observe heart changes over 24 months. During the study, participants will be monitored from the time of consent for up to 78 months. Evaluations will occur at the start and every six months afterward to track mortality and heart failure-related health events. Researchers will gather data on heart function, treatment effects, and safety. The main analysis will consider all patients as originally assigned, and additional analysis will assess those who received the assigned treatment.

Researchers are evaluating whether the introduction of dedicated hospital-based HIV teams can improve HIV testing rates among patients with HIV indicator conditions across ten European countries. This real-world, multicenter, stepped-wedge cluster randomized effectiveness-implementation trial spans four years and involves hospitals in the Netherlands, Belgium, United Kingdom, Germany, Spain, France, Italy, Romania, Poland, and Ukraine. The study aims to address the current gap in HIV testing and improve early diagnosis by comparing testing rates before and after the implementation of HIV teams. The intervention involves creating local HIV teams led by HIV specialists, supported by nurses and data collectors. These teams focus on auditing and providing feedback to healthcare professionals to encourage HIV testing when indicated, reducing stigma, educating staff on HIV prevention and care, and improving linkage to local prevention services. The HIV teams use electronic health records to identify patients with HIV indicator conditions and integrate their activities into routine hospital care. Participants' data are collected retrospectively from routine care and prospectively at the healthcare professional level. Researchers measure changes in HIV testing rates, new HIV diagnoses, and variations across countries and specialties. They also assess the HIV diagnosis and care cascade, healthcare professionals' knowledge and stigma levels, and implementation outcomes such as resource use and cost-effectiveness. Monitoring includes feedback loops and evaluation of barriers and facilitators to implementation, aiming to improve HIV testing and care sustainability in hospitals.

Researchers are investigating the drug bezuclastinib in an open-label, two-part Phase 2 study for patients with Advanced Systemic Mastocytosis (AdvSM), including Aggressive Systemic Mastocytosis (ASM), Systemic Mastocytosis with an Associated Hematologic Neoplasm (SM-AHN), and Mast Cell Leukemia (MCL). The study aims to evaluate the safety, effectiveness, and how the drug behaves in the body for these serious conditions. Bezuclastinib is given orally as tablets taken continuously in 28-day cycles. The study has two parts: Part I focuses on identifying safe and tolerable doses of bezuclastinib over 18 months, while Part II evaluates its effectiveness by measuring the objective response rate and confirming the relationship between drug exposure and response during another 18-month period. Participants will undergo assessments including clinical evaluations, laboratory tests, and monitoring of their disease status to determine treatment effects and safety. Researchers will track the drug's impact on the disease and patient health throughout the study, which involves continuous treatment and follow-up over the specified time frames.

Researchers are evaluating the safety and effectiveness of elenestinib (BLU-263) combined with symptom-directed therapy (SDT) compared to placebo plus SDT in people with indolent systemic mastocytosis (ISM) whose symptoms are not well controlled by SDT alone. This Phase 2/3 randomized, double-blind, placebo-controlled study includes participants with ISM and smoldering systemic mastocytosis, and also involves groups for pharmacokinetic studies and participants who previously received a selective KIT inhibitor. The study is divided into multiple parts. Parts 1 and 2 enroll participants with ISM who will receive either elenestinib oral tablets or placebo alongside their symptom-directed therapy. Participants from Part 2 may continue into Part 3, which is an open-label extension where all receive elenestinib. Part K enrolls participants with ISM who have prior experience with selective KIT inhibitors. The study tracks treatment effects and safety over time. Participants will be monitored for up to 5 years, with assessments including the number of treatment-emergent adverse events, changes in symptom scores measured by the ISM-Symptom in Assessment Form, and overall safety monitoring. Evaluations occur at baseline, 13 weeks, 49 weeks, and throughout the long-term follow-up. The study also includes detailed tracking of symptom control and adverse events to evaluate the impact of treatment on participants' health and quality of life.

Researchers are working to create a comprehensive reference database focused on intracranial aneurysms (IA). This project aims to gather detailed clinical history, imaging data, biological samples, and other related information to better understand risk markers for aneurysm formation and rupture, along with prognostic factors for different management strategies. The study also seeks to develop patient-specific management protocols and assess how the database and its tools can improve care, reduce costs, and support new discoveries and industrial developments. Participants include patients with newly diagnosed or known intracranial aneurysms, healthy volunteers, and family members of patients with a familial history of IA. Data collected includes demographic details, medical history, imaging scans such as MRI angiography and CT angiography, and various biological samples like blood, cerebrospinal fluid, saliva, and stool. Participants are asked to provide consent for data and sample use, including genetic analysis and potential future research applications. There are no limits on the number of participants for this database. During the study, participants will provide access to their health records, complete questionnaires, and undergo imaging and sample collection. Researchers will track clinical outcomes, imaging results, and quality of life measures over time. The primary outcome is disease model validation over 5 years. Consent includes provisions for confidentiality, withdrawal without impact on care, and possible re-contact for additional information or consent. The study ensures safety through ethical oversight and insurance coverage for any direct harm related to participation.

Researchers are evaluating the effectiveness of delgocitinib cream 20 mg/g applied twice daily compared to a cream vehicle in treating adults with mild to severe palmoplantar pustulosis (PPP). This phase 2a, double-blind, two-arm trial focuses on adults diagnosed with PPP, a condition characterized by persistent pustules on the palms and/or soles, lasting more than three months. The study aims to assess skin improvement using the PPP Area and Severity Index (PPPASI) and other clinical evaluations over 16 weeks. Participants will be randomly assigned to apply either delgocitinib cream or the cream vehicle twice daily during a 16-week treatment period. The study involves approximately 9 visits over about 18 weeks in total. The trial is designed to compare the two treatments' effects on PPP severity, with a thorough monitoring process throughout the study period. During the trial, participants will undergo clinical assessments including photographic evaluations to confirm PPP diagnosis, PPPASI scoring to measure skin improvement, and physician global assessments. Safety and treatment adherence will be closely monitored. The main outcome measure is the number of participants achieving at least a 75% improvement in PPPASI score from baseline at week 16. The study also includes safety checks and follow-up to ensure participant well-being throughout the trial.

This research aims to evaluate the effects of litifilimab (BIIB059), a monoclonal antibody, in adults with active subacute or chronic cutaneous lupus erythematosus (CLE), with or without systemic lupus erythematosus (SLE). Participants have active skin symptoms of CLE that have not improved with antimalarial therapy or had difficulties continuing that treatment. The study focuses on reducing skin disease activity using several scores including CLA-IGA-R and CLASI, while also assessing safety, immune response, and quality of life. Participants will be randomly assigned to receive either litifilimab or a placebo injection under the skin every four weeks during a 24-week double-blind period where neither participants nor researchers know which treatment is given. After this, all participants will receive litifilimab injections every four weeks for an additional 28 weeks. Those who complete the treatment may join a long-term extension study or enter a follow-up safety period lasting up to 24 weeks. Total participation may last up to 80 weeks. Throughout the study, researchers will monitor skin disease activity using the CLA-IGA-R erythema score and the CLASI-A activity score to see how many participants improve. They will also assess safety, tolerability, immune system effects, and participants' quality of life using questionnaires. These evaluations occur regularly during both treatment periods and follow-up to understand the impact of litifilimab on CLE symptoms and overall health.

Researchers are investigating how well MSP-2020, a drug capsule, binds to serotonin type 2A receptors (5-HT2AR) in the brains of healthy male adults aged 23 to 55. The study also evaluates the presence and duration of MSP-2020 and its metabolite in the blood and monitors the safety of the drug. This phase 1, open-label trial focuses on brain imaging to understand receptor occupancy after a single oral dose of MSP-2020. Participants receive a single oral dose of MSP-2020 and undergo positron emission tomography (PET) scans to measure how the drug attaches to brain receptors. The study includes collecting blood samples to analyze drug concentration, peak levels, time to peak, half-life, and overall drug exposure within two days after dosing. The trial is conducted in a controlled research unit where participants remain for up to four days. During the study, participants undergo various assessments including medical history, physical and neurological exams, ECG, echocardiogram, and laboratory tests to ensure health status. Safety is closely monitored, including brain imaging and blood tests during the first two days. The main outcomes measured are changes in receptor binding and pharmacokinetic properties of MSP-2020. Participants are expected to stay in the research unit for the duration of the study to complete all procedures and monitoring.

Researchers are evaluating whether an investigational drug called OHB-607 can prevent Bronchopulmonary Dysplasia (BPD), a common chronic lung disease, in extremely premature infants. The study compares infants receiving OHB-607 alongside standard neonatal care to those receiving standard care alone to reduce the burden of this lung condition. This is a Phase 2b, multicenter, randomized, open-label study focused on safety and clinical efficacy. Participants will receive an intravenous infusion of OHB-607 from birth until reaching a postmenstrual age (PMA) of 29 weeks and 6 days. The study includes two arms: one group receives the investigational drug plus standard care, while the other group receives only standard neonatal care. The treatment period ends at 29 weeks plus 6 days PMA, after which infants are monitored. Throughout the study, researchers will track the incidence of severe BPD or death up to 36 weeks PMA, whichever occurs first. Assessments will include clinical evaluations and monitoring for safety and any side effects. The study also involves long-term follow-up to observe the infants' health outcomes beyond the treatment period. Participation involves consent from parents and collection of birth and medical history information.

Researchers are studying whether combining calderasib, a targeted therapy for the KRAS G12C mutation, with subcutaneous pembrolizumab can treat non-small cell lung cancer (NSCLC). The study aims to determine if people receiving calderasib with pembrolizumab live longer without their cancer growing or spreading compared to those receiving pembrolizumab with chemotherapy. This is a phase 3, randomized, open-label, multicenter clinical trial focusing on participants with advanced or metastatic nonsquamous NSCLC carrying the KRAS G12C mutation. Participants will receive one of two treatment combinations. One group will take calderasib orally along with subcutaneous pembrolizumab and berahyaluronidase alfa injections. The other group will receive subcutaneous pembrolizumab combined with chemotherapy drugs pemetrexed and a platinum-based drug, either carboplatin or cisplatin, administered by intravenous infusion. These treatments are given as first-line therapy, and the study evaluates their safety and effectiveness. During the study, researchers will monitor participants for progression-free survival, especially focusing on those with at least 1% PD-L1 tumor proportion score, for up to approximately 48 months. Participants will undergo regular assessments to track cancer progression and response to treatment. Safety and efficacy data will be collected throughout the study to understand how well the treatments work and their side effects over time.
