Active clinical trials for "COVID-19"

The COVID-19 pandemic has had dramatic effects on health systems and on non-COVID health care. Using French inpatient claims data and retrospectively collected clinical data, the investigators will assess the changes in hospital admissions for acute cardiovascular and neurovascular conditions in France during and after the national lockdown.

Safety and Effectiveness Evaluation of Seraph 100 Microbind Affinity Blood Filter (Seraph 100) in the treatment of patients with COVID-19

A randomized double blind control trial will be done. Total 188 Covid-19 patients will be enrolled in this trial who are RT-PCR confirmed case of mild cases. Before enrollment, base line investigations will be done and as per eligibility criteria 188 (one hundred eighty eight) patients of mild symptoms will be selected by random sampling. Ninety four diagnosed patients (Group-A) of Covid-19 will be in the experimental group and 94 Covid-19 diagnosed patients (Group-B) will be in the control group. Group -A will be given combination treatment of Tab Ivermectin and Cap Doxycycline along with standard therapy and Group -B will be treated by standard therapy with placebo. Follow up will be done every day in both group with all the parameters as stated above and will be documented. On 5th day of treatment, if fever subsides final outcome will be measured by result of RT-PCR test preferably from one designated lab with sample of nasal swab for all. Subject to RT-PCR test negative result again on 6th day another RT-PCR test will be done at 24 hours apart. But if RT-PCR test result remain positive on 5th day, again on 10th day same test is to be done and also on 11th day subject to test result as negative on 10th day. Death of the patients will be documented as well. Regarding safety issues of the drugs we shall monitor for any SAE and would report to the DSMB for proper management guideline

Considering the potential of mesenchymal stromal cells (MSCs) in the treatment of lung injuries by COVID-19, this pilot clinical trial evaluates the safety and potential efficacy of the cell therapy, administered intravenously, in patients with pneumonia associated with COVID-19-associated acute respiratory distress syndrome.

The coronavirus disease (COVID-19) epidemic represents a major therapeutic challenge. The highly contagious severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) and the long duration of the disease have led to a massive influx of patients admitted in health services and intensive care units. According to current knowledge, there are no treatments that prevent the spread of the infection, especially in exposed populations, or the disease progression to a severe form. Daily active smokers are infrequent among outpatients or hospitalized patients with COVID-19. Several arguments suggest that nicotine is responsible for this protective effect via the nicotinic acetylcholine receptor (nAChR). Nicotine may inhibit the penetration and spread of the virus and have a prophylactic effect in COVID-19 infection. However, the epidemic is progressing throughout French territory and new variants (in particular the "English B1. 1.7 variant of SARS-COV-2") much more contagious run a risk of accelerating the epidemic in the population. The anti-SARS-COV-2 vaccines recently launched (or being evaluated) represent great hope in this health crisis, but trials were only able to show their effectiveness on symptomatic forms of SARS-COV-2 infection. On the one hand, the vaccination compaign for the entire population requires many months,which leaves many unprotected subjects waiting. In addition, there is currently no evidence of a protective role of vaccines against asymptomatic forms of COVID-19 and therefore on SARS-COV-2 transmission. Finally, the nicotine patches may protect people in hight-risk areas/periods until they are vaccinated (if they accept it and are eligible for it) and in the post-vaccination weeks necessary for the effectiveness of the vaccine,which reinforces the importance of evaluating this alternative prevention strategy, in the context of the arrival of vaccines

This study aims to analyze the effectiveness and safety of Avigan® (favipiravir) compared to Oseltamivir as an adjuvant therapy among adult COVID-19 patients. This study will be conducted in a hospital setting, recruiting adult COVID-19 patients with mild, moderate, and severe symptoms. Subjects will be randomly given Favipiravir or Oseltamivir as an adjuvant therapy to standard COVID-19 treatment. Patients will be followed up for 21 days after the first dose of intervention given. The primary outcomes of this study are the improvement of radiology results and RT PCR negative conversion during follow up. The secondary outcomes are adverse events, hospital length of stay (LOS), and Case fatality rate (CFR)

This trial is focusing on blood pressure control for patients with high blood pressure (hypertension) during the COVID-19 pandemic when seeing a doctor for advice may be difficult. The study utilises remote consultations by telephone or video conferencing. Patients record blood pressure and data into an electronic diary on their phone which is reviewed in consultations every 2 weeks by a clinician. Medication for this trial is amlodipine as an oral solution which is uptitrated accordingly for patients receiving medication (anticipated 200). 800 patients will be in an observational group recording the same readings and will not receive any medication.

This clinical trial will be a blinded, randomised study to determine the safety, reactogenicity, and immunogenicity of a second booster dose of SARS-CoV-2 vaccines in adults enrolled over two consecutive stages. Stage 1 will commence at the time of study approval and transition to stage 2 once bivalent vaccines are approved and available in Australia.

Data from some studies indicate the decline in the effectiveness of the authorized COVID-19 vaccines due to antibody waning following vaccination and the emergence of different variants. These findings support the need to increase vaccination and booster campaigns to protect the adult population against infection. Valneva developed the VLA2001 vaccine, a highly purified, whole virus SARS-CoV-2 vaccine produced on Vero cells and inactivated with β-propiolactone. VLA2001 will be adjuvanted with the licensed adjuvant cytosine phospho-guanine (CpG) 1018 (produced by Dynavax, contained in HEPLISAV-B®) in combination with aluminum hydroxide. On April 14, 2022, VLA2001 was granted Conditional Marketing Authorization (CMA) by the Medicines and Healthcare products Regulatory Agency (MHRA) of the United Kingdom for primary immunization in adults 18 to 50 years of age. This follows the emergency use authorization granted by the Bahraini NHRA in March 2022. As a substantial population has received a primary vaccination series with authorized vaccines, a booster dose to extend the duration and protection may be required.This study aims to investigate the safety, tolerability, and immunogenicity of the VLA2001 vaccine as a booster dose to adults 18 years and older who were primed with another licensed inactivated COVID-19 vaccine at least 6 months prior to enrollment.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has affected the global population with significant morbidity and mortality. One of the main concerns is the management of the patients since there is no specific treatment for this condition. Therefore, in SARS-CoV-2 patients the compassionate use of off-label therapies has been initiated; such as the use of plasma from convalescent patients. This treatment has been used in other pandemics like SARS-CoV-1, H5N1, H1N1, Ebola, among others. This study is a phase II/III randomized clinical trial to assess the effectiveness and safety of convalescent plasma administration in patients with high-risk SARS-CoV-2.
