NCT07530016
Melasma is a common pigmentation disorder among young and middle-aged women, characterized by symmetrical brown-black patches on the face. It is related to genetics, ultraviolet radiation, endocrine factors and inflammation, and can lead to psychological problems and affect quality of life. Current treatments such as hydroquinone stimulation, laser therapy, and oral tranexamic acid have a high recurrence rate and poor compliance. The new gel formulation, which combines tranexamic acid (to inhibit tyrosinase), aloe polysaccharides (anti-inflammatory and repair), and lauric azon (promotes penetration), is expected to enhance efficacy and reduce side effects. This study aims to explore its clinical efficacy and synergistic mechanism, providing new strategies for the treatment of Melasma.
NCT05005403
Cancer is a condition where cells in a specific part of body grow and reproduce uncontrollably. Non-Small Cell Lung Cancer (NSCLC) is a solid tumor, a disease in which cancer cells form in the tissues of the lung. Head and Neck Squamous Cell Carcinoma (HNSCC) is a solid tumor, a disease in which cancer cells form in the tissues of the head and neck. The purpose of this study is to assess adverse events and pharmacokinetics of azirkitug as a monotherapy and in combination with budigalimab, bevacizumab, or telisotuzumab adizutecan. Bevacizumab is an approved product, while budigalimab, azirkitug, and telisotuzumab adizutecan are investigational drugs being developed for the treatment of NSCLC, HNSCC, and other solid tumors. Study doctors put the participants in groups called treatment arms. The maximum-tolerated dose (MTD)/maximum administered dose (MAD) of azirkitug will be explored. Each treatment arm receives a different dose of azirkitug in monotherapy and in combination with budigalimab, bevacizumab, or telisotuzumab adizutecan. Approximately 694 adult participants will be enrolled in the study across approximately 80 sites worldwide. Participants will receive azirkitug as a monotherapy or in combination with budigalimab, bevacizumab, or telisotuzumab adizutecan as an Intravenous (IV) Infusion for an estimated treatment period of up to 2 years. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

This study is a first-in-human (FIH) study of BMS-986340 in participants with advanced solid tumors.
NCT06939374
ICECAP is a multi-centre, prospective, single-arm, interventional, traditional feasibility clinical investigation to evaluate the efficacy and safety of intra-coronary cryotherapy on vulnerable or high-risk plaque (HRP), using the CryoTherapy System (CTS). The study aims to enroll 25 patients with symptomatic coronary artery disease, successfully treated for their culprit lesion and with presence of at least one HRP lesion in another vessel. Eligible patients will undergo cryotherapy during a planned procedure. Near-infrared spectrometry (NIRS and Optical Coherence Tomography imaging will be used during baseline procedure, and during a 9 months follow visit. The primary endpoint is reduction of plaque burden measured as 30% reduction in maxLCBI4mm as measured by NIRS at 9 months post procedure.
NCT07485985
Refractory angina due to advanced obstructive coronary artery disease (CAD) remains a major clinical problem with limited evidence-based treatment options. The coronary sinus reducer (CSR) is an hourglass-shaped stainless-steel mesh device designed to create a controlled narrowing of the coronary sinus (CS). By increasing CS pressure, CSR implantation may improve myocardial perfusion and reduce anginal symptoms, although the physiological mechanisms underlying this effect remain incompletely understood. REDUCE-ANGINA is a prospective observational study investigating the hemodynamic effects of CSR implantation in 25 patients with refractory angina and advanced CAD. The study evaluates the interaction between coronary sinus hemodynamics and coronary arterial blood flow before and after CSR implantation. The main study endpoints include changes in coronary sinus pressure, coronary flow reserve, microvascular resistance reserve, and absolute microvascular resistance from baseline to 6 months, measured using continuous flow thermodilution during saline-induced coronary hyperemia.
NCT06571370
The purpose of this study is to demonstrate substantial equivalence between Pression's Wave PRO System and a commercially available predicate ECP device to support a U.S. 510(k) submission for the Wave PRO System.
NCT04332653
The main purposes of Phase 1b of this study are to determine the following in participants with advanced solid tumors: * Safety and tolerability of NT-I7 in combination with pembrolizumab * Maximum Tolerated Dose (MTD) and/or the Recommended Phase 2 Dose (RP2D) The main purpose of Phase 2a of this study is to assess the preliminary anti-tumor activity of NT-I7 in combination with pembrolizumab in participants with checkpoint inhibitor (CPI) treated and naïve relapsed and refractory (R/R) tumors. The main purpose of the Biomarker Cohort is to assess a potential correlation between tumor infiltrating lymphocytes (TILs) and clinical benefits in participants with CPI-naïve R/R ovarian cancer (OC).
NCT07449429
This study develops and validates a privacy-preserving OCR-LLM pipeline that converts admission history of present illness (HPI) records into structured coronary syndrome subtypes (STEMI, NSTEMI, unstable angina, and chronic coronary syndrome). The system first extracts text from de-identified HPI images using locally deployed OCR, then applies large language models with a fixed diagnostic prompt to generate subtype classification and evidence. Performance is evaluated in an internal validation cohort and multiple external datasets covering heterogeneous EHR templates, emergency department cases, and an English dataset from MIMIC-IV. A clinician usability study assesses changes in diagnostic accuracy and time with and without tool assistance.
NCT07444957
This prospective, multicenter, post-market observational study aims to evaluate the safety and effectiveness of the crystalline sirolimus-coated balloon (SeQuent® Sirolimus-Coated Balloon) for the treatment of coronary artery disease in routine clinical practice. Consecutive, unselected adult patients undergoing percutaneous coronary intervention for de novo coronary lesions or in-stent restenosis will be enrolled. The primary objective is to assess target lesion failure at 12 months, defined as the composite of target vessel myocardial infarction or ischemia-driven target lesion revascularization. Secondary objectives include angiographic procedural success, major adverse cardiovascular events, bleeding outcomes, and longer-term clinical results up to 36 months, as well as outcomes across predefined anatomical and clinical subgroups. The study seeks to answer whether treatment with the crystalline sirolimus-coated balloon provides a safe and effective revascularization strategy in a real-world population with diverse clinical presentations and lesion characteristics.
NCT07446465

NCT06788275
Endothelial dysfunction is one of the aetiological factors in ischaemic heart disease (IHD). Aerobic exercise is effective in improving endothelial function, as measured by flow-mediated dilation (FMD), in patients with IHD. Within the aerobic exercise methods, there is evidence showing that high-intensity interval training (HIIT) increases FMD to a greater extent than moderate-intensity training (MIT) in these patients. Notably, in a recent review, our research group found that only studies performing long bouts of HIIT (long HIIT: higher than 1 min) found a greater effect on FMD, while no differences were found in those studies using short bouts of HIIT (short HIIT: ≤ 1 min) and MIT. However, no experimental studies comparing the effect of long HIIT, short HIIT, and MIT on endothelial function, as well as other predictors of mortality, such as cardiorespiratory fitness, brain-derived neurotrophic factor (BDNF) levels or parasympathetic branch activity, have been performed. Therefore, the main objective of this project will be to compare the effect of the three aerobic exercise methods on endothelial function, as measured by FMD, in patients with IHD. Complementarily, the effect of aerobic exercise, depending on the exercise method, on different mortality predictors will be compared. For this purpose, a multicentre randomised study will be carried out (2 hospitals in Elche and one in Alicante). Assessors will be blinded to the patients allocation. Participants will be aware about their allocation in the experimental groups due to the nature of the study. A total of 132 men and women with IHD (66 per sex), diagnosed between three and 12 months before the start of the intervention, aged between 45 and 75 years, and without limitations for the practice of exercise training, will be recruited. All patients will train 3 days a week for 12 weeks. Participants will be assessed before the intervention (i.e., pre), at 6 weeks of training (i.e., mid) and after the intervention (i.e., post). Physiological and psychological variables will be registered in the assessment periods. Training intensity will be individually prescribed based on the cardiopulmonary exercise test (CPET). Intensity exercise will be adapted after the first part of the intervention. Analysis of covariance will be used to compare the values of the three groups after the intervention for the continuous variables, including the pre-intervention value as a covariate, while a logistic regression model will be used for the categorical variables.
NCT07432620
The goal of this observational study is to learn whether combining stress echocardiography (stress echo) results with routine clinical information can better predict important heart outcomes in adults (18+) with chest pain who were assessed for suspected coronary artery disease. The main questions it aims to answer are: Can an artificial intelligence / machine learning model using stress echo findings plus clinical factors (such as blood pressure, diabetes, smoking, other health conditions, medications, and body measurements) predict major heart-related events (such as heart attack, stroke, death related to heart disease, or the need for coronary procedures) more accurately than stress echo results alone? Can the model help identify which patients are most likely to benefit from further invasive assessment and possible coronary revascularisation (for example, a stent or bypass surgery)? Which combination of stress echo measurements and clinical factors contributes most to risk prediction? Participants will: Not be asked to attend extra visits or have additional tests for this study. Have their existing stress echo reports and routinely collected hospital record data analysed (approximately 3,000 people who previously had dobutamine stress echo at Milton Keynes University Hospital). In some cases, if outcomes are not fully available from hospital records, the research team may check additional sources (such as GP records, or contacting the patient if appropriate) to confirm whether a major heart-related event occurred.
NCT07422818
This is a single-center, prospective interventional study evaluating noninvasive coronary function testing using transthoracic Doppler echocardiography of the left anterior descending coronary artery in patients with stable angina and nonobstructive coronary artery disease (ANOCA) who previously underwent invasive coronary function testing (adenosine and/or acetylcholine). A group of age- and sex-matched healthy volunteers will be enrolled to support interpretation of potentially abnormal noninvasive responses observed in patients.
NCT07281716
Phase 1b/2 open-label study evaluates the safety, tolerability, and efficacy of combination immunotherapy with nadunolimab (anti-IL-1RAP) and toripalimab (anti-PD-1) in patients with chemotherapy-refractory metastatic microsatellite stable (MSS) colorectal cancer. Phase 1b will assess dose-limiting toxicity (DLT), while Phase 2 will evaluate objective response rate (ORR), including progression-free survival (PFS), overall survival (OS), disease control rate (DCR), and duration of response (DOR). Exploratory analyses will investigate immunomodulatory effects through tumor and peripheral blood studies, and treatment will continue every 3 weeks for up to 1 year or until disease progression.
NCT07386418
ORBITA-SOLAR is an invasive physiological cardiac catheterisation study that aims to determine whether different coronary stenoses have different angina thresholds. The angina threshold is defined as the amount of coronary flow reduction required to reproduce symptoms. Sixty patients with symptoms of stable angina and 2 coronary artery stenoses amenable to percutaneous coronary intervention (PCI) will be recruited. This study will use intra-coronary balloon inflation during supine exercise on an ergometer to measure the fractional flow reserve (FFR) and non-hyperemic pressure ratio (NHPR) that relates to angina onset, in real time, at the location of each stenosis.
NCT07412795
The goal of this clinical study is to learn whether gum treatment can improve heart health. Researchers will compare blood markers related to heart disease before and after routine gum treatment. The main questions this study aims to answer are: Is gum disease a risk factor for heart disease? Can treating gum disease lower the risk of heart disease? Adults with stable angina (a type of heart disease) and adults without heart disease may take part in this study. All participants will receive routine, non-surgical gum treatment, which is a standard dental care procedure. This includes professional cleaning to remove plaque and tartar from the teeth and practical education on tooth brushing and cleaning between the teeth. The treatment will be performed by a single researcher and completed in one visit within about one hour. Participants will: Provide a blood sample before gum treatment Receive routine, non-surgical gum treatment Return after three months for a follow-up visit Provide a second blood sample This study does not involve experimental drugs or devices. Participation is voluntary, and there is no cost to participants. The results may help researchers better understand how gum health is related to heart health.
NCT04475380
Drug eluting stents (DES) are widely used for treatment of coronary artery lesions. The Xience Sierra stent has a refined design of the metal stent backbone and is used in patients with various clinical syndromes and in different lesions. Clinical outcome of patients with previously unknown (silent) diabetes and prediabetes is of increasing interest since the latter group has recently shown to be associated with a significant risk of adverse cardiovascular events after treatment with contemporary DES. Outcome data in a population of high-risk all-comer patients, including many patients with diabetes mellitus and prediabetes, would be of great interest, but such data are not available yet. In addition, there is a lack of data in a general all-comer population. Therefore, the COASTLINE study will primarily assess the safety and efficacy of the Xience Sierra stent in a general all-comer population as well as a high-risk all-comer population.
