Active clinical trials for "COVID-19"

In December 2019, new coronavirus pneumonia (COVID-19) erupted in Wuhan (Hubei, China) and quickly spread from a single city to the entire country in just 30 days and then attracted worldwide attention. COVID-19 causes a large number of deaths due to its occurrence in many cases. This virus caused a total of 549,461 approved cases and 24,887 deaths worldwide. All the countries of the world take some precautions to prevent the spread of this epidemic disease, which WHO declared it as "pandemic". Staying home and social isolation are at the top of these precautions. For this purpose, in Turkey on March 21, 2020, '65 and older individuals began to apply the curfew to individuals with chronic illnesses. However, not leaving the house and social isolation brings with it the limitation of physical activity. Physical activity (PA) is defined by WHO as any bodily movement produced by the contraction of skeletal muscles that increases energy consumption. Recommended PA levels for the elderly (≥65 years) are similar to adults (18 to 64 years old). At the global level, approximately 45% of people over the age of 60 do not meet the recommended level of PA. Studies investigating the relationship between social isolation and health behavior report consistent findings. Individuals with smaller social networks report less healthy diets, excessive alcohol consumption, and less physical activity. The effects of social isolation are related to physical inactivity, smoking and the possibility of having both health risk behaviors together. The decrease in physical performance is associated with the risk of falling, sarcopenia, fragility, decreased quality of life, emotionalization, comorbidity, early death, and increased health care costs. Practical and innovative interventions are needed to reduce the decline in muscle mass, strength and physical performance in the aging population. When today's conditions are evaluated, technology-supported education programs are effective in increasing the motivation for physical activity. The purpose of this study; to evaluate the physical activity level of individuals over the age of 65 who experience social isolation due to the precautions taken in our country to prevent the spread of the COVID-19 pandemic, and to investigate the effectiveness of home-based telerehabilitation exercises. It is aimed to use an innovative model based on the digitally supported, home-based exercise program.

This study is a research project to evaluate the efficacy of hydroxychloroquine for post-exposure prophylaxis and early treatment of Covid-19. The intervention entails administering prophylactic hydroxychloroquine to all contacts (Study 1) and treating non severe confirmed cases with hydroxychloroquine (Study 2).

Uganda hosts 1.4 million refugees, making it Sub-Saharan Africa's largest refugee host community and the third largest globally. Adolescents and young people (AYP) comprise half of the world's 70.8 million forcibly displaced persons, yet they are understudied in pandemics, including in COVID-19. Poverty, overcrowded living conditions, and poor sanitation likely elevate forcibly displaced persons' COVID-19 risks by limiting their ability to practice mitigation strategies. There continue to be significant knowledge gaps regarding the implementation and effectiveness of behaviour change interventions on improving COVID-19 prevention practices (i.e. hand and respiratory hygiene, physical distancing). mHealth (healthcare delivered by mobile phones) is cost-effective, aligned with how youth learn and socialize, vital for physical distancing, and has been used for COVID-19 messaging in other low- and middle-income countries. Nested within an ongoing HIV self-testing cluster-randomized trial, this study aims to develop, implement, and evaluate the effectiveness of an mHealth intervention in increasing COVID-19 prevention practices with displaced/refugee AYP aged 16-24 in Kampala, Uganda. Participants will be enrolled in a 8-week mHealth social group intervention program that is informed by the RANAS (Risks, Attitudes, Norms, Abilities, and Self-Regulation) approach to Water, Sanitation, and Hygiene. Using a pre-test/post-test design, this study will assess changes in participants' self-efficacy (e.g. ability, confidence, adherence) in COVID-19 prevention practices.

The primary goal of the village-level intervention is to assess whether mask-wearing reduces community-level COVID-19 seroconversion. The individual experiment assess whether masks protect against COVID-19 seroconversion. It also assesses the efficacy of high-quality cloth vs. surgical masks.

The purpose of the study is to assess if the study medication (molnupiravir, MK-4482) will prevent symptomatic coronavirus disease 2019 (COVID-19) in adults who live with someone with confirmed COVID-19 infection. This is a phase 3, multicenter, randomized, double-blind, placebo-controlled study; half of the study participants will receive molnupiravir twice daily by mouth and the other half will receive a placebo. The primary objectives of the study are to determine if molnupiravir prevents symptomatic COVID-19 disease and to evaluate its safety and tolerability. All participants who develop COVID-19 during the study are still eligible for any COVID-19 treatment recommended by their doctor.

The current COVID-19 pandemic is the biggest global healthcare challenge in the last century, and the number of cases in the next 12 months is likely to increase. There is currently no proven treatment, chemoprophylaxis or vaccine against COVID-19, which exhibits a wide clinical spectrum from asymptomatic carriage to mild upper respiratory tract infection, severe viral pneumonia to acute respiratory distress syndrome and death. Key workers are at high risk of exposure highlighting the need for effective preventative strategies. SARS-CoV-2 is a positive-sense single-stranded enveloped RNA virus which transmits via droplets, aerosols and direct contact, to reach their target naso- and oropharyngeal epithelial cells through initial electrostatic interactions to cell surface heparan sulphate (HS) proteoglycans. Carrageenan mimics cell surface HS, thereby trapping the virus to allow mucociliary clearance and has demonstrated anti-viral activity in-vitro and in a number of common cold clinical trials when administered as a nasal spray. ICE-COVID a randomised, double blind, placebo-controlled phase III trial of the prophylactic efficacy of iota-carrageenan nasal and throat spray in preventing COVID-19 illness in at risk healthcare professionals. Participants (n=240) will be randomly allocated to either the treatment arm (verum Coldamaris plus, 0.12% iota-carrageenan plus 0.04% Kappa-Carrageenan in 0.5% saline) or placebo (Coldamaris sine, saline 0.5%) arm. The study's primary objective is the prevention of COVID-19 infection, confirmed by PCR swab or documented seroconversion. Secondary objectives are to determine if carrageenan sprays reduce the clinical severity of COVID-19 and symptomatic acute respiratory infection of other aetiologies (non-SARS-CoV-2).

This is the first study of COVI-VAC in humans. The purpose of the study is to evaluate the safety and immune response of COVI-VAC (a live attenuated vaccine to prevent COVID-19) in healthy adults aged 18 to 30 years. Approximately 48 participants will be enrolled into 1 of 3 dose groups (low, medium, high). Within each of these dose groups, participants will be assigned randomly to receive either 2 doses of COVI-VAC 28 days apart, 2 doses of placebo (saline), or 1 dose of COVI-VAC and 1 dose of placebo. COVI-VAC or placebo is administered by drops into each nostril. Neither the participants nor the researchers will know whether COVI-VAC or placebo has been received. To assess the safety of the vaccine, each participant will record symptoms and oral temperature in a diary daily for 14 days after each dose. Safety laboratory tests, physical exams, ECGs, and a chest X-ray will also be performed, and peak expiratory flow and vital signs will be measured. Adverse events and medication use will be recorded. Blood samples and intranasal samples will be collected to assess the immune response from the vaccine.

The primary objective of the randomized observer-blinded phase 2b/3 part of this trial is to demonstrate the efficacy of a 2-dose schedule of CVnCoV in the prevention of first episodes of virologically-confirmed cases of COVID-19 of any severity in SARS-CoV-2 naïve participants. The primary objective of the open-label phase of this trial is to evaluate safety in all participants ≥ 18 years of age remaining in the trial after unblinding.
