Active clinical trials for "Hypersensitivity"

Lung cancer is the second most common malignancy and mortality rate in the world. In the United States and Europe, approximately 10% to 15% of NSCLC patients have epidermal growth factor receptor (EGFR)-sensitive mutations, with higher mutation rates of 30% to 40% in Asia, and objective response rates (ORRs) of 76% to 80% with EGFR Tyrosine Kinase Inhibitor (TKI)-targeted therapy. However, resistance mechanisms such as EGFR, MET, PIK3CA and BRAF gene alterations occur with the development of resistance to EGFR-TKI therapy; Median Progression Free Survival (mPFS) for only 2.8-3.2 months; The median overall survival (mOS) is only 7.5-10.6 months. Due to the variety of mechanisms of resistance to EGFR-TKIs and the limited efficacy of chemotherapy, it is necessary to provide salvage treatment for advanced non-small cell lung cancer that is positive for EGFR-sensitive mutations and has failed EGFR TKIs. Anlotinib is a novel multi-target tyrosine kinase inhibitor (TKI) used to inhibit tumor angiogenesis and proliferative signaling. The main targets of anlotinib include tyrosine kinase vascular endothelial growth factor receptor 1-3 (VEGFr1-3), fibroblast growth factor receptor 1-4 (Fibroblast Growth Factor Receptor 1-4), platelet-β derived growth factor receptor α and β, and stem cell factor receptor. Anlotinib is rapidly absorbed through the intestine, has high bioavailability, a half-life of 5 days, and is convenient for oral administration, which is conducive to improving patient dependence. IN MAY 2018, THE CHINA FOOD AND DRUG ADMINISTRATION APPROVED ANLOTINIB FOR MARKETING, ENTERED THE MEDICAL INSURANCE CATALOG IN OCTOBER OF THE SAME YEAR, AND WAS RECOMMENDED BY THE CHINESE SOCIETY OF CLINICAL ONCOLOGY (CSCO) FOR THE THIRD-LINE TREATMENT OF LUNG CANCER IN 2019. Penpulimab is a humanized immunoglobulin G1 monoclonal antibody (IgG1), which is a class 1 new drug jointly developed by Zhongshan Akeso Biopharmaceutical Co., Ltd. and Chia Tai Tianqing Pharmaceutical Group Co., Ltd., which can specifically bind to PD-1 molecules on the surface of T lymphocytes, thereby blocking the PD-1/PD-L1 pathway that leads to tumor immune tolerance, and reactivating the anti-tumor activity of T lymphocytes to achieve the purpose of treating tumors. A number of preclinical in vitro trials have verified the effect of PEAMPLIMAB in blocking PD-1 pathway, and the results of preclinical pharmacodynamics, animal pharmacokinetics and toxicology have shown that PEAMPLIMAB has good stability, reduced host cell protein residues, and can effectively bind to antigens, and eliminate Fc-mediated effector function, with higher safety. AK105-201 is a multicenter, double-blind, randomized controlled, phase III clinical trial evaluating the efficacy and safety of pianpulimab combined with carboplatin + paclitaxel in the first-line treatment of locally advanced or metastatic squamous non-small cell lung cancer, the primary endpoint of the study was PFS, and the secondary endpoint was OS, and the results showed that the mPFS group of pianpulimab and the control group were 7.6m and 4.2m, respectively, and the HR was 0.44, reducing the risk of disease progression by 56%. In the 2022 CSCO guidelines for the diagnosis and treatment of non-small cell lung cancer, peamplimab combined with platinum-containing chemotherapy is recommended as the first-line treatment for stage IV driver-free squamous cell carcinoma Grade II. In advanced patients with EGFR TKIs resistance, pemetrexed chemotherapy has a good efficacy, with a median PFS of 2.83 months and a response rate of 22%. The AK105-203 study is a multicenter phase II clinical study led by Professors Jiao Shun and Bai Li of the Chinese PLA General Hospital of the People's Liberation Army of Anlotinib combined with péamplimab in the first-line treatment of hepatocellular carcinoma, with a median follow-up of 23 months and mPFS of 8.8 months. Therefore, based on the results of the current study on immunosuppressants and antiangiogenic drugs for the treatment of NSCLC, and the current research status in patients with advanced NSCLC who are positive for EGFR-sensitive mutations and have failed EGFR TKIs, we expect to conduct an exploratory clinical study of PD-1 antibody (péamplimab) combined with anlotinib in patients with advanced NSCLC who are positive for EGFR-sensitive mutations and have failed EGFR TKIs, with the aim of evaluating the safety of this combination, It was further investigated whether this combination could further improve the survival benefit of patients with advanced NSCLC.

Within a survey of adolescent males in Medellin schools (mainly 13-year old boys) the researchers are randomizing whether survey respondents answer sensitive questions themselves or are asked the questions by an enumerator. Questions are of three main varieties: (1) antisocial behaviors, (2) symptoms of depression, and (3) symptoms of anxiety.

The primary purpose of the study is to assess the muscle contractility and sensitivity of lumbar erector spinae, biceps femoris, and gluteus maximus short-term response to Tabata kettlebell swing protocol.

Tree nut immunotherapy Route Assessment and DEvelopment (TRADE) is a randomized controlled trial that evaluates the efficacy and safety of sublingual immunotherapy and lower, more tolerable, doses of oral immunotherapy than currently in use.

This is a clinical trial using CPI-0209 in combination with Carboplatin chemotherapy followed by CPI-0209 maintenance in patients with platinum sensitive, recurrent ovarian cancer.

The maintenance of lean body mass, especially skeletal muscle, is vital for optimal health and performance across the lifespan. The protein component of lean body mass is in a constant state of turnover, involving the simultaneous breakdown of old and/or damaged proteins and the synthesis of new proteins. These processes collectively determine if someone gains or loses lean body mass. Eating a protein-rich meal or performing resistance exercise can stimulate protein synthesis to gain lean body mass. Stable isotope "tracers" are amino acid building blocks that are slightly heavier than those naturally found in the body. In research, these are often used to assess changes in protein turnover in response to feeding and/or exercise. However, traditional stable isotope tracer methods involve the intravenous delivery of a tracer with blood sampling and muscle biopsies, which may be cumbersome or unfeasible for some for participants. The investigators have recently developed and validated a non-invasive 'breath test' in males that measures the efficiency of the body for using amino acids in food to build new body proteins. The principle of this method is that leucine, an essential amino acid that the body must acquire from normal diet, can be used to build new body proteins or as a source of energy (i.e., oxidized). Since leucine is preferentially used in skeletal muscle, skeletal muscle protein metabolism can be non-invasively inferred . Any leucine "tracer" that is oxidized can be detected and measured in the carbon dioxide exhaled. It has been observed that less dietary leucine is oxidized when active males perform a bout of resistance exercise, meaning more was used to build muscle proteins. When performed habitually, resistance exercise can help skeletal muscles grow, compared to a rested-state, resulting in greater leucine retention in the body to build new proteins. Therefore, the purpose of this study is to validate this non-invasive breath test in females to increase the validity of the method in a wider range of populations. Ultimately, the results will further validate this non-invasive tool that can potentially detect whether different populations are sensitive to dietary amino acids and in a position to gain or lose lean body mass.

By achieving effective cooperation between the Children's Hospital Srebrnjak (CHS), the Reference center for clinical allergology in children of the ministry of health, and IN2 Ltd., part of Constellation Software Inc., it is planned to develop an IT platform for the introduction of personalized balanced nutrition in kindergartens. The collected data which include the screening of the population, anthropometrical measurements, physical activity status, and medical examination, will be used to create a Registry of Allergies. Through the implementation of research activities, it is expected to develop an IT platform for personalized balanced nutrition of preschool children, which consists of a developed information system for continuous monitoring using a website and/or a mobile application.

Non-celiac gluten/wheat sensitivity (NCGS/NCWS) is a syndrome characterized by both intestinal (irritable bowel syndrome [IBS]-like presentation) and extraintestinal symptoms (headache, migraine, "foggy mind", depression, anxiety, fibromyalgia, joint and muscle pain, leg or arm numbness, eczema or skin rash), which occur after the ingestion of gluten/wheat in subjects in which celiac disease (CD) and wheat allergy diagnosis has been previously excluded. NCGS/NCWS symptoms generally occur after the ingestion of gluten/wheat, disappear within a few days of a gluten-free diet (GFD) and quickly reappear when gluten/wheat is reintroduced. A new assay, recently available on the Italian market, allows to ascertain the presence of immunogenic peptides of gluten (Gluten Immunogenic Peptides, GIP) in the urine and stool. The test might allow to ascertain if the NCGS/NCWS patients, on GFD, eat, even accidentally, gluten. Of the 2 available assays, the urinary one allows the patient himself to test the presence of GIP in relation to symptoms/signs appearing and/or social activities (e.g. meal in a restaurant). The aims of the present study are: 1) to test, in patients with NCGS/NCWS on GFD, the adherence to the elimination diet; 2) to evaluate the correlation between the symptoms' reappearance and the presence of GIP in the urine.

Drug Hypersensitivity Syndrome or DRESS for "Drug Reaction with Eosinophilia and Systemic Symptoms" is a serious drug allergy which can be life-threatening for patients with serious organ damage. The pathophysiology of DRESS is still not fully understood. In particular, no study has focused on the characterization of eosinophils, while paradoxically eosinophilia is one of the diagnostic criteria. Likewise, there is no data about the origin of eosinophils and few data are available concerning immune polarization of T-cells or the involvement of innate lymphoid cells type 2 in the recruitment of eosinophils. Our preliminary data on increase activation markers membrane expression of cutaneous eosinophils suggest that this approach could allow the identification of endotypes in which eosinophils are involved and contribute to organ damages. The correlation between tissue infiltration of eosinophils and their degree of activation would then justify the development of targeted therapeutic strategies in DRESS syndrome (anti-IL-5 therapy?). The aim of the project is: 1) Evaluate the activation status of circulating and cutaneous eosinophils in patients with DRESS compared with drug induced maculopapular exanthema without or with eosinophilia (but do not fulfill DRESS criteria) and healthy subjects; 2) Understand the pathophysiological mechanisms at the origin of this eosinophilia.

BACKGROUND: Anaphylaxis is the most severe form of allergy that rapidly affects multiple body systems and can be deadly. The highest incidence of anaphylaxis is in children and adolescents. In Canada, approximately every 10 minutes there is an Emergency Department (ED) visit for food allergy, and up to 80% of anaphylactic reactions in children are triggered by food. The ambiguity in how physicians manage anaphylaxis adds a huge burden to health care and further contributes to ED crowding. Current Canadian and international treatment guidelines universally recommend that all patients present to the ED for a prolonged period (6-24 hours) of in-hospital monitoring after initial reactions have been treated, to increase detection of biphasic anaphylaxis (BA). BA is a second wave of symptoms after initial resolution. These guidelines are based on poor or little evidence and have unintended negative impacts on patient safety and quality of life. Furthermore, this 'one-size fits all' approach to care leads to wasteful resource utilization that provides low value care. OBJECTIVE: The main objective of the study is to derive a clinical prediction rule that identifies children with anaphylaxis who are at risk of BA. METHODS: This prospective multicenter cohort study will enroll 1682 patients from 7 pediatric EDs that are members of the Pediatric Emergency Research Canada (PERC) network. We will enroll patients < 18 years of age presenting to the ED with an allergic reaction that matches the diagnostic criteria of anaphylaxis. Research assistants (RA) present in the ED will screen, obtain consent, and prospectively collect all study data. The Research Assistant or Research Nurse will follow patients during their ED visit and ascertain, in conjunction with the medical team, if the patient developed biphasic anaphylaxis in the ED. A standardized follow-up survey conducted within 2-5 days of ED or hospital discharge will determine if a biphasic reaction occurred following ED disposition. We established an advisory council comprised of end-users and community partners external to the project team to monitor project milestones. STUDY TEAM: We have established an international multidisciplinary team of experts in pediatrics, emergency medicine, allergy/immunology, research methodology and statistics, and knowledge translation. Our team is supported by the PERC network. EXPECTED OUTCOME: Providing the best evidence-based, value care at the lowest cost is a moral and ethical imperative. Therefore, in alignment with national and international research priorities, we propose to develop a robust prediction model for BA. This model will address a significant gap in current knowledge and practice, with anticipated benefit for patient care and health system efficiency worldwide. This trial will generate novel, clinically relevant data on optimal ED management of children with anaphylaxis that integrates best value care with patient safety.
