NCT ID: NCT04902989 Recruiting - Allergic Rhinitis Clinical Trials

Environmental Pollutants and Their Effects on Respiratory Allergy

Start date: March 10, 2021
Phase:
Study type: Observational

In Latin America and the Caribbean, more than 100 million people are exposed to higher levels of pollution than those recommended by WHO. The objective of the study is to determine the relationship between exposure to environmental pollutants and the prevalence and exacerbation of respiratory allergy. It is an observational, prospective, longitudinal and descriptive study that will include subjects older than 6 years who come to the consultation of the Regional Center for Allergy and Clinical Immunology with a diagnosis of respiratory allergy, positive skin tests and who live in Monterrey and its metropolitan area. After verbal assent, the subject's address and work area will be registered, the Rhinitis Control Assessment Test and the Asthma Control Test as well as spirometry will be made. The geolocation of industries and avenues near the address and work area of subjects will be carried out, as well as the determination of pollutants and pollens by the Integral Monitoring System (SIMA) and the Pollen Sense device. Subsequently, the correlation between exposure to pollutants and respiratory allergy will be analyzed. Dispersion models will be built considering pollutants and climatic factors (precipitation, wind speed, humidity and temperature). By carrying out this project, it will be possible to contribute to the identification of the factors that lead to the development and exacerbation of allergic respiratory diseases and subsequently propose the implementation of measures for their control and recommendations for prevention to the population.

NCT ID: NCT04901052 Completed - Obesity Clinical Trials

Effects of n-3 Intake on Lipid Profile, Biochemical and Inflammatory Markers in Subjects With Obesity

Start date: January 10, 2018
Phase: N/A
Study type: Interventional

Obesity is a chronic disease characterized by the excessive accumulation of adipose tissue that is harmful to health. Dietary habits modification through a caloric restriction, macronutrient distribution including linoleic and linolenic (n-6:n-3) polyunsaturated fatty acids (PUFAs) ratio, has been suggested for obesity management. It has been proposed that the optimal n-6: n-3 ratio should be between 1:1 and 5:1 to maintain a healthy balance. Purpose: Compare the effect of a diet n6:n3 ratio of polyunsaturated fatty acids with a group supplemented with n-3 PUFA on lipid profile in erythrocyte membrane, biochemical and inflammatory markers in subjects with obesity. Methods: 58 subjects were randomly divided into two groups: fish oil group and the placebo group. Anthropometric and biochemical data were evaluated, cytokine levels was performed using the Bio-PlexPro™ HumanTh17Cytokine Assays (MagPix) panel. The fatty acid profile quantification in the erythrocyte membrane was carried out by gas chromatography. Statistical analysis was performed with Statistical Package for the Social Sciences (SPSS) v.22 software.

Start date: October 11, 2021
Phase: Phase 2
Study type: Interventional

The purpose of this study is to evaluate the effectiveness, safety and tolerability of Afimetoran in participants with active Systemic Lupus Erythematosus (SLE). The extension period will provide additional long-term safety and efficacy data and enable those participants initially randomized to placebo to receive treatment with Afimetoran.

NCT ID: NCT04895358 Active, not recruiting - Breast Neoplasms Clinical Trials

Study of Pembrolizumab (MK-3475) Plus Chemotherapy Versus Placebo Plus Chemotherapy for HR+/HER2- Locally Recurrent Inoperable or Metastatic Breast Cancer (MK-3475-B49/KEYNOTE-B49)

Start date: June 18, 2021
Phase: Phase 3
Study type: Interventional

The safety and efficacy of pembrolizumab plus the investigator's choice of chemotherapy will be assessed compared to placebo plus the investigator's choice of chemotherapy in the treatment of chemotherapy-candidate hormone receptor-positive, human epidermal growth factor receptor 2-negative (HR+/HER2-) locally recurrent inoperable or metastatic breast cancer. The primary hypotheses are that the combination of pembrolizumab and chemotherapy is superior to placebo and chemotherapy in regards to Progression-Free Survival (PFS) or overall survival (OS) in participants with programmed cell death-ligand 1 (PD-L1) combined positive score (CPS) ≥1 and ≥10.

NCT ID: NCT04895267 Active, not recruiting - COVID-19 Clinical Trials

Low-field Thoracic Magnetic Stimulation Increases Peripheral Oxygen Saturation Levels in COVID-19 Patients

Start date: July 3, 2020
Phase: N/A
Study type: Interventional

This study aimed to present a proof-of-concept that a 30 minutes single-session of low-field thoracic magnetic stimulation (LF-ThMS) on the dorsal thorax can be employed to increase oxygen saturation (SpO2) levels in coronavirus disease (COVID-19) participants significantly. The investigators (Saul M. Dominguez-Nicolas and Elias Manjarrez) hypothesized that the variables associated with LF-ThMS, as hyperthermia, frequency, and magnetic flux density in the dorsal thorax, might be correlated to SpO2 levels in these participants. The investigators designed a single-blind, sham-controlled, crossover study on COVID-19 participants who underwent two sessions of the study (real and sham LF-ThMS), and other COVID-19 participants who underwent only the real LF-ThMS.

NCT ID: NCT04895241 Recruiting - Clinical trials for Lupus Erythematosus, Systemic

A Study to Learn About the Safety of Litifilimab (BIIB059) Injections and Whether They Can Improve Symptoms of Adult Participants Who Have Systemic Lupus Erythematosus

TOPAZ-1
Start date: May 25, 2021
Phase: Phase 3
Study type: Interventional

In this study, researchers will learn more about a study drug called litifilimab (BIIB059) in participants with systemic lupus erythematosus (SLE). The study will focus on participants who have active disease and are already taking standard of care medications. These may include antimalarials, steroids, and immunosuppressants. The main objective of the study is to learn about the effect litifilimab has on lowering the activity of the disease. The main question researchers want to answer is: - How many participants have an improvement in their symptoms after 52 weeks of treatment? Researchers will answer this and other questions by measuring the symptoms of SLE over time using a variety of scoring tools. These include the SLE Responder Index (SRI), the Systemic Lupus Erythematosus Disease Activity Index-2000 (SLEDAI-2K), and the Patient Global Assessment - Visual Analog Scale (PGA-VAS). Researchers will also learn more about the safety of litifilimab. They will study how participants' immune systems respond to litifilimab. Additionally, they will measure the effect litifilimab and SLE have on the quality of life of participants using a group of questionnaires. The study will be done as follows: - After screening, participants will be randomized to receive either a high or low dose of litifilimab, or placebo. A placebo looks like the study drug but contains no real medicine. - All participants will receive either litifilimab or placebo as injections under the skin once every 4 weeks. The treatment period will last 52 weeks. Participants will continue to take their standard of care medications. - Neither the researchers nor the participants will know if the participants are receiving litifilimab or placebo. - There will be a follow-up safety period that lasts up to 24 weeks. - In total, participants will have up to 22 study visits. The total study duration for participants will be up to 80 weeks.
