Active clinical trials for "COVID-19"

To evaluate by intravascular OCT study the presence of microvascular pulmonary thrombosis in patients with COVID-19, high D-dimer levels and contrast CT scan negative for pulmonary thrombosis. We'll also evaluate the extension of microvascular pulmonary thrombosis in patients with contrast CT scan positive for pulmonary embolism in areas where contrast CT scan was negative.

Novel corona virus (SARS-CoV-2) epidemic which stared from Wuhan in China is now a well established pandemic worldwide. After Italy, Spain, Germany, United Kingdom and USA, India is at the edge of becoming the next epicentre of this Pandemic. If adequate preventive and therapeutic measures are not taken, India has very high risk of affecting million of people with high mortality because of the large population along with very high population density. At present there are no definitive therapeutic drugs or vaccine are available for the treatment and prevention of SARS-CoV-2 infection. Symptomatic and supportive care are being given to COVID-19 cases along with isolation and quarantine measure are being taken for the suspected individual at risk for COVID-19 to limit the spread of the SARS-CoV-2 infection . Among the all the drugs being used for the treatment of COVID-19, hydroxychloroquine (HCQ), has given some rays of hope to battle against this deadly pandemic. HCQ has some anti viral effect against SARS-CoV in vitro. HCQ is quite safe and being used in rheumatology patients for lifelong without much side effect, so it allow for higher dose without any significant side effects and drug-drug interaction. Recently published clinical trial suggested HCQ can be used for the therapeutic purpose of the SARS-CoV-2 infection. Indian council of medical research (ICMR) has advised for HCQ prophylaxis for all asymptomatic health care workers involved in taking care of suspected or confirmed COVID-19 cases and all asymptomatic household contacts of labarotory confirmed COVID-19 cases. But there is still lack of significant scientific data to prove or disprove the efficacy of HCQ for the treatment and post exposure chemo-prophylaxis for SARS-CoV-2 infection. Being a tertiary care centre we are catering many states which include Punjab, hariyana, himachal Pradesh, Uttara khand, Uttar Pradesh. Among this Punjab have highest population of non residential Indian (NRI) and most of them have returned home. This put our institute to handle highest burden of suspected cases of SARS-CoV-2 in northern India. So we have planned this open level control clinical trial to evaluate the efficacy of post exposure prophylaxis (PEP) with HCQ for the prevention of COVID-19 in asymptomatic individuals who are at risk for SARS-CoV-2 infection. All asymptomatic individuals who have undertaken international travel in last 2 weeks and all asymptomatic individual with direct contact with laboratory confirmed cases will be advised for home quarantine for 2 weeks along with social distancing and personal hygiene. They will be given the option for taking HCQ prophylaxis. These quarantined asymptomatic individuals will be assigned into one post exposure prophylaxis (PEP) group and one control group as per inclusion and exclusion criteria. Individual who will not give consent for HCQ prophylaxis and those with contraindication for HCQ therapy like, hypersensitivity to HCQ or 4-aminoquinolone derivatives, patients with known retionopathy, cardiac arrhythmia, G6PD deficiency, psoriasis and pregnancy will be directly included in the control group. All symptomatic individual, and all health care workers related to suspected or proven COVID-19 will be excluded from the study. The PEP group will receive tablet HCQ 400 mg q 12 hourly on day one followed by 400 mg once weekly for 3 weeks (total cumulative dose of 2000 mg). The control group will not receive HCQ. Both the groups will receive standard care of therapy in the form of home quarantine for 2 weeks along with social distancing and personal hygiene. They will be followed up for 4 weeks telephonically or physically as and when required and will be enquired regarding development of any COVID-19 symptoms like fever, cough, sore throat, shortness of breath, diarrhoea, myalgia.During follow up nasopharyngeal and or throat swab of the participants will be taken for processing reverse transcription polymerase chain reaction (RTPCR) for the detection SARS-Cov-2 RNA to confirm CoVID-19. Samples for RTPCR will be taken when any asymptomatic participants become symptomatic and by the 5-14 days of contact in asymptomatic participants through in-hospital visit at the institute's communicable disease ward isolation. The participant with RTPCR positive and with or without symptoms will be defined as definite COVID-19 case and the RTPCR negative symptomatic participant will be defined as probable COVID-19 case. Asymptomatic participants with negative RTPCR will be defined as non-COVID case. Incidence of COVID-19 or probable COVID-19 or non-COVID case in previously asymptomatic participants will be compared between the PEP and control groups.

The study is designed as a multicenter, randomized, double-blind, placebo-controlled, parallel group study of the safety and efficacy of tofacitinib in hospitalized adult participants with COVID-19 pneumonia who are receiving SoC therapy and who are not on HFNC, noninvasive ventilation, invasive mechanical ventilation, or ECMO on Day 1 at the time of randomization. Participants with laboratory confirmed SARS-CoV-2 infection as determined by a positive PCR or other commercially available or public health assay, who have agreed to participate will be screened within 48 hours after hospitalization to determine eligibility. This should be completed within 48 hours prior to Day 1. Eligible participants will be randomized on Day 1 in a 1:1 ratio to the tofacitinib treatment group or the placebo treatment group and will receive treatment for up to 14 days, or until discharge from the hospital, whichever is earlier. If a participant requires intubation prior to the end of the 14-day treatment period, they will continue to receive tofacitinib or matching placebo until Day 14 (or until discharge from the hospital, if earlier than Day 14), if clinically appropriate. Participants will be assessed daily (up to Day 28) while hospitalized for clinical, safety, and laboratory parameters. Follow-up visits will occur on Day 28, 28 to 35 days after the ET/ED/EOT visit, and on Day 60. An independent, external DSMB will be convened to oversee the safety of participants and make recommendations regarding the conduct of the trial in accordance with the Charter.

The primary objective of this study is to evaluate the safety and efficacy of intravenous (IV) infusion of ulinastatin compared to placebo with respect to time to recovery, disease severity, need for ventilator support, and mortality in patients with COVID 19.

This study is a randomized, double-blinded, and placebo controlled phase Ⅰ/Ⅱ clinical trial of the SARS-CoV-2 inactivated vaccine manufactured by Sinovac Research & Development Co., Ltd. The purpose of this study is to evaluate the safety and immunogenicity of the experimental vaccine in healthy adults aged 18~59 Years.

There is an urgent need to evaluate interventions that can prevent the infection with SARS-CoV 2 of healthcare workers at risk. Melatonin is an inexpensive and safe product with protective effect in both bacterial and viral infections likely due to its anti-inflammatory and anti-oxidative effects. This randomized controlled trial seeks to evaluate is efficacy as a prophylaxis in healthcare workers exposed to the virus in their clinical practice.

This study is a Phase 1, open label, non-randomized, two-arm interventional clinical trial to evaluate the safety and efficacy of Virazole® in hospitalized adult patients who have tested positive for COVID-19 and, as a result, have significant respiratory distress (PaO2/FiO2 ratio <300 mmHg).

TAK-919 is a vaccine in development to protect people against Covid-19. The main aims of the study are to learn if TAK-919 can protect people from Covid-19 and to check for side effects from TAK-919. At the first visit, the study doctor will check if each person can take part. Those who can take part will be chosen for 1 of 2 treatments by chance. Participants will either receive an injection of TAK-919 or a placebo in their arm. In this study, a placebo will look like the TAK-919 vaccine but will not have any medicine in it. 3 times as many participants will receive TAK-919 than placebo. Participants will receive 2 injections of TAK-919 or placebo, 28 days apart. Participants will be asked to record their temperature and any medical problems in an electronic diary for up to 7 days after each injection. During the study, participants will visit the clinic for regular check-ups, blood tests, and sometimes for nose swab samples. When all participants have visited their clinic 28 days after their 2nd injection, the study sponsor (Takeda) will check how many participants have made enough antibodies to protect them against Covid-19. The participants will stay in the study for up to 12 months after they have had their 2nd injection. During this time, the study doctors will continue to check how many participants have made enough antibodies to protect them against Covid-19. Also, they will check if participants have any more side effects from TAK-919 or the placebo.

This is a prospective, randomized placebo-controlled double blinded clinical trial in frontline healthcare workers managing COVID-19 patients. Participants will be weekly tested for SARS-CoV-2 and a panel of respiratory viruses. Treatment will be 3times a day for 84 days one puff into each nostirl and 3 puffs into mouth. Daily a symptom score will be recorded. The primary objective of the trial is to demonstrate that prophylactic treatment of health care workers managing COVID-19 patients with iota-carrageenan reduces symptoms of SARS-CoV-2 infections as well as infections with other respiratory viruses when compared to a placebo-treated control group.

The study will evaluate the efficacy, safety, and immunogenicity of two vaccination schedules of an inactivated vaccine against SARS-CoV-2 infection in adults. Two doses of the vaccine will be administered in a 0,14 and a 0,28-day schedule. Follow-up of safety and efficacy will be assessed for 12 months after the first dose. Immunogenicity will be studied in a subgroup of participants.
