Researchers are investigating whether a multifactorial lifestyle intervention involving a Mediterranean diet with reduced calories and increased physical activity can help middle-aged adults 30-50 years with metabolic syndrome lose weight and maintain that weight loss over time. The study also aims to understand the social and demographic challenges people face in sticking to these healthy habits and to examine the lifestyle patterns of this group. Participants will be randomly assigned to one of two groups. One group will follow general lifestyle recommendations from primary healthcare providers, while the other will receive an intensive program that includes monthly individual and group sessions over 6 months to encourage a Mediterranean diet with 25% fewer calories and physical activity based on WHO guidelines. The goal for the intervention group is to reduce their initial weight by 5-10% within 6 months and maintain this loss after 12 months. Throughout the study, participants will undergo assessments including measurements of weight, waist size, blood sugar, triglycerides, and glycated hemoglobin to monitor changes in their health. Data on demographics, diet, clinical parameters, and laboratory tests will be collected. After the 6-month intervention, a follow-up at 12 months will evaluate how well participants maintain their lifestyle changes. The study emphasizes tracking adherence and identifying factors that help or hinder long-term weight loss maintenance.

Researchers are evaluating the use of personalized, dynamic titanium prostheses made with 3D printing to reconstruct the chest wall after tumor removal or severe trauma. This study addresses the challenges of traditional rigid reconstruction methods that can cause pain or breathing difficulties by testing implants designed to mimic natural rib movement, potentially improving function and comfort. The study is a multicenter, ambispective registry collecting both retrospective and prospective data across major Spanish hospitals. The treatment involves creating a custom 3D-printed titanium prosthesis based on preoperative CT scans, manufactured using titanium alloy powder. During surgery, the prosthesis is implanted and anchored to the ribs or sternum to restore chest wall integrity while preserving natural dynamics. The study includes retrospective cases and prospective enrollment over 24 months, with follow-up evaluations at discharge, 1 month, 6 months, and 12 months post-surgery. Participants will undergo assessments including pulmonary function tests, pain scales, imaging like X-rays and CT scans, and quality of life questionnaires. Data is securely stored and anonymized in a centralized database compliant with European data protection laws. The primary outcomes measure changes in lung function parameters over one year. Participants can withdraw at any time, and the study aims to improve prosthesis design and surgical practices through comprehensive monitoring and analysis.

Researchers are investigating the effectiveness of the Pontic-shield technique in preserving the alveolar ridge after tooth extraction. This study compares this technique with two other approaches ridge preservation using deproteinized bovine bone and a porcine collagen membrane, and no intervention after extraction fresh socket. The trial aims to understand which method better maintains bone structure, addressing challenges in long-term dental implant success. The study is a three-arm randomized clinical trial. Participants are assigned to one of three groups the experimental group receiving the Pontic-shield technique, where a 1mm thick fragment of the tooth root is left in place the positive control group receiving ridge preservation with bovine bone and collagen membrane and the negative control group receiving no insertion after extraction, allowing the blood clot to form naturally. A cone-beam computed tomography scan is done before extraction and again four months after to evaluate bone changes. Participants will undergo tooth extraction and assigned treatment. Their bone resorption is measured from extraction day to four months after. Satisfaction is also assessed using a visual analogue scale during the first week post-surgery. The study includes adults aged 18 to 80 who require extraction of specific teeth and agree to participate. Safety and healing are monitored throughout. Total follow-up lasts at least four months after extraction to assess outcomes.

This research aims to evaluate whether creating dedicated HIV teams in hospitals across ten European countries can increase HIV testing rates among patients showing signs of HIV-related conditions. The study uses a stepped-wedge design, where hospitals switch from routine care to the new intervention in sequence. This approach compares outcomes before and after the teams are in place, helping to understand the impact of the intervention across various locations and medical specialties. The intervention involves establishing local HIV teams led by specialists and supported by nurses and data experts. These teams identify patients needing HIV tests through electronic health records, provide feedback to doctors to encourage testing, offer education to healthcare staff about HIV, reduce stigma, and improve connections to prevention and care services. This program integrates smoothly into regular hospital routines and aims to close gaps in HIV diagnosis. Participants HIV testing rates will be monitored by reviewing records before and after the intervention. Researchers will also assess new HIV diagnoses, changes in testing patterns by country and specialty, and healthcare professionals knowledge and attitudes toward HIV. The study includes ongoing evaluation of how well the teams operate, resource use, and cost-effectiveness. Data collection extends up to several years to observe long-term effects, with continuous monitoring of care access and prevention services.

Researchers are investigating CGT9486, also known as bezuclastinib, in an open-label Phase 2 study for patients with Advanced Systemic Mastocytosis AdvSM.

The study aims to evaluate the safety, effectiveness, pharmacokinetics, and pharmacodynamics of bezuclastinib in this patient population. Participants will receive bezuclastinib tablets orally, taken continuously in 28-day cycles. The study is divided into two parts Part I focuses on identifying effective and tolerable dosing exposures over 18 months, while Part II evaluates the drugs efficacy by measuring objective response rates and confirming the exposure-response relationship, also over 18 months. Additional assessments include effects on mutation allele burden, serum tryptase levels, histopathologic changes, spleen and liver volume, and safety monitoring. During the study, participants will undergo various clinical evaluations, including laboratory tests, imaging to monitor organ size changes, and assessments of disease response and progression. Researchers will track adverse events and pharmacokinetic profiles throughout the 18 months. The study involves continuous monitoring of participants to understand the treatments impact on survival and disease progression over this period.

Researchers are evaluating the safety and effectiveness of elenestinib BLU-263 combined with symptom directed therapy SDT compared to placebo plus SDT in adults with indolent systemic mastocytosis ISM whose symptoms are not well controlled by SDT alone. This randomized, double-blind, placebo-controlled Phase 23 study includes multiple parts to assess different doses and durations of elenestinib treatment, including an open-label extension for participants finishing earlier phases. The study also enrolls participants who have previously received an approved selective KIT inhibitor and includes pharmacokinetic groups. Participants receive oral elenestinib or placebo once daily alongside SDT, which is personalized based on individual symptom management needs. Part 1 focuses on short-term treatment lasting up to 12 weeks, while Part 2 extends treatment to approximately 48 weeks. Part 3 and other parts allow treatment for up to about 5 years. The study monitors participants through these phases to evaluate how elenestinib affects symptoms, disease markers, and safety over time. During the study, participants undergo regular assessments of symptoms using the ISM-Symptom Assessment Form ISM-SAF, laboratory tests including serum tryptase and KIT D816V allele levels, bone marrow evaluations, and quality of life measures. Researchers track adverse events and changes in disease-related factors at various points up to 5 years. This thorough monitoring helps measure treatment effects and safety over both short and long-term periods, with total participation lasting several years depending on the study part.

Researchers are evaluating the combination of CGT9486 and sunitinib compared to sunitinib alone in patients with locally advanced, unresectable, or metastatic Gastrointestinal Stromal Tumors GIST. This Phase 3, open-label international trial involves multiple parts, including dose confirmation, drug interaction assessments, and efficacy comparisons. The study also includes substudies focusing on drug-drug interaction potential and first-line treatment in patients with specific genetic mutations KIT exon 9.

Researchers are investigating new treatment options for meningiomas that continue to grow despite local therapies like surgery or radiotherapy. This trial focuses on evaluating a precision medicine approach that combines PET-based imaging to select patients with tumors expressing somatostatin receptors and a targeted radioligand therapy called 177Lu-DOTATATE. This is the first randomized clinical trial studying this therapy in patients with meningiomas that have not responded to other treatments. Participants will be randomly assigned to one of two groups. One group receives 177Lu-DOTATATE through intravenous infusions every four weeks for a total of four cycles. The other group receives local standard care, which may include treatments like hydroxyurea, bevacizumab, sunitinib, octreotide, everolimus, or observation with supportive care, based on the investigators choice. This study is designed to compare the effects of 177Lu-DOTATATE against various standard treatments in this patient population. During the study, participants will undergo regular MRI scans to measure tumor size and progression. Researchers will also assess overall survival, neurological function, quality of life, and treatment side effects over a period extending up to two years after enrollment. Monitoring includes imaging, laboratory tests, and health questionnaires to evaluate how the disease and treatments affect participants over time.

Researchers are evaluating the safety and effects of a medicine called Ritlecitinib for adults with moderate to severe hidradenitis suppurativa HS, a condition that causes long-lasting painful red lumps on the skin. The study focuses on participants who have not responded well to or cannot tolerate antibiotics for HS. This Phase 2, randomized, double-blind, placebo-controlled study aims to understand how Ritlecitinib compares to placebo in treating this condition. Participants will be randomly assigned to take either Ritlecitinib or a matching placebo by mouth once daily at home. The study includes a loading dose of Ritlecitinib for the first 8 weeks, followed by a maintenance dose for the next 8 weeks, totaling 16 weeks of treatment. The placebo group will follow the same schedule with a pill that looks like the study medicine but contains no active drug. Throughout the study, participants will have about 10 clinic visits over approximately 24 weeks, including screening, Day 1, and follow-ups every 1, 2, or 4 weeks until Week 16. At these visits, health status will be reviewed through physical exams, blood and urine tests, vital signs, chest X-rays, ECGs, hearing tests, and questionnaires. Participants will also record daily medication intake and HS symptoms using a mobile eDiary. Researchers will measure skin response and safety outcomes to assess the effects of the study medicine compared to placebo.

Researchers are conducting a Phase 3, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of rilzabrutinib in adults with active Immunoglobulin G4-related disease IgG4-RD. The study aims to measure the time to the first adjudicated disease flare and assess other important outcomes such as flare-free rates, disease activity control, glucocorticoid use, and safety parameters including adverse events, laboratory tests, and electrocardiograms ECG. Participants will be assigned to one of two groups one receiving rilzabrutinib tablets and the other receiving placebo tablets, both administered orally. The treatment period lasts 52 weeks in a double-blind manner, preceded by a 4 to 6 week screening period. After treatment, there is a 2-week follow-up, with an optional open-label extension lasting up to 108 weeks. The study includes a total of 16 visits during the main period and up to 9 additional visits during the optional extension. During their participation, adults diagnosed with IgG4-RD will undergo repeated imaging procedures such as CT, MRI, PET, or ultrasound to assess disease status. Researchers will monitor disease flares, remission status, glucocorticoid dosage, clinical activity scores, laboratory values, vital signs, and ECG results. Safety monitoring continues up to week 160 to capture treatment-emergent adverse events. Overall, participation lasts up to 60 weeks, with possible extension for those continuing in the optional phase.
