COVID-19 Clinical Trials and Expanded Access

This is a clinical trial to evaluate the safety and immunogenicity of a recombinant adenovirus 5 vectored COVID-19 vaccine (Ad5-nCoV) with two doses and with different adminstration routes in healthy adults aged 18 years and older.

The first version of this preprint article is registered on the 4th of May 2020 under the digital object identifier of:10.31219/osf.io/u56fc. COVID-19 infections virus spread worldwide and impact many countries with sever economical sequences. The effective antiviral medication or vaccination for the virus is unavailable until the present date and it takes months or years to discover the effective treatment or test the efficacy of the discovered treatment. Based on these facts, the human immune system against the virus may have an effective role to regulate the infection and reduce the mortality rate among the infected patients. This proposed research article aims to explore the available medication/ natural supplementation to boost the immunity system of the patients against COVID-19 infections and reduce the mortality rate among infected patients. Methods: a proposed clinical trial will be carried out to investigate the effect of the different treatment modalities on the human immune system against COVID-19 infection.

Quarantine separates persons who have been potentially exposed to an infectious agent (and thus at risk for disease) from the general community. However, it may create psychological, emotional, and financial problems for some persons. The experience of those placed under quarantine in terms of compliance, difficulties, emotional response and psychological impact remains under-researched. In view of the increasing cases of COVID-19 in India and the rising numbers of people being quarantined as a precautionary measure, it was imperative to assess those quarantined for the psychological impact of the concerns regarding this illness and the quarantine procedure. In India, no such study had been undertaken and our study thus filled the research gap. The cross-sectional observational study aims at assessing the psychological impact of quarantine on Indian BSF jawans (n=100). They would be assessed for depression, anxiety, perceived stress level of impact, and impact of life events using Beck Depression Inventory, State Trait Anxiety Inventory, Perceived Stress Scale, and Impact of Events Scale-Revised. A qualitative interview schedule will also be carried out. Data would be analysed.

This is a phase 2, single or multi-center, randomized, double-blind placebo-controlled study to evaluate the safety and efficacy of Rayaldee (CTAP101 Capsules) to treat adult subjects with mild to moderate COVID-19 who test positive for SARS-CoV-2 via nasopharynx swab and subsequent reverse transcription polymerase chain reaction (RT-PCR).

The primary objective of this study is to evaluate the efficacy of BGB-DXP593 administered intravenously as a single dose in participants with mild to moderate COVID-19

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

The purpose of this research study is to look at high dose zinc versus multivitamin micronutrient supplementation to support immune health in the setting of the COVID-19 pandemic.

Since March 2020, the SARS-CoV type coronavirus infection (SARS-CoV-2; nCoV19; COVID-19) is considered pandemic. As early as April 2020, the World Health Organization recommended the implementation of mass screening of populations, with the aim of identifying cases and contacts and controlling viral spread. Since the end of lock-down on May 11, 2020,the screening policy has been intensified to fight against COVID-19. Virological tests by RT-PCR are thus accessible to all, without a prescription and reimbursed by health insurance. The French government has also set a quantitative target of 1 million tests per week. In order to meet this target, the number of sampling centers has been increased (mobile structures, etc.). Screening tests are currently carried out using a nasopharyngeal swab analyzed by RT-PCR for the detection of viral RNA. This type of sample has several technical and logistic constraints. It must be carried out by personnel who are authorized and trained in this procedure and in appropriate hospital hygiene practices. It exposes the sampling personnel to possible contamination through nasopharyngeal secretions or coughing that may occur during sampling. With the increase in screening, there are sometimes insufficient numbers of sampling personnel and there is significant market pressure for swabs and virological transport media. In addition, these swabs are uncomfortable or even painful for the patient, which could imply a reluctance to be screened. They are also complicated in children, whether they are rhino- or oropharyngeal. An alternative to the nasopharyngeal swab, which is the subject of this project, would be to have one or more reliable sampling methods that are less restrictive than the nasopharyngeal swab ("gold standard"). Thus, we propose to test and compare the results obtained by molecular biology techniques on nasopharyngeal, salivary and buccal swabs.

Evaluate the safety pharmacokinetics and pharmacodynamics (PK/PD)of a single dose of Kamada anti-severe acute respiratory syndrome (SARS)- CoV-2 in patients hospitalized with COVID-19 caused pneumonia

It is an established fact that, corona virus spread through the respiratory droplets. Colonization of the virus in oropharynx and/or nasopharynx is considered to be major factor for transmissibility of the virus through respiratory secretions. Preventing colonization of the virus by administrating povidone iodine in the nasal passage therefore, a rational thought which is supported by recent evidence of in-vitro virucidal action of povidone iodine in Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS CoV-2). Therefore, the study is designed to assess the virucidal effect of povidone iodine on COVID-19 virus in-vivo.This open label randomized clinical trial will be conducted at Department of Otorhinolaryngology and Head Neck Surgery, in collaboration with Department of Virology and Department of Medicine in Dhaka Medical College (DMC) Hospital. The study will be conducted from September 2020 to October 2020. Total 175 confirmed cases of COVID-19 disease, proven by Reverse transcription polymerase chain reaction (RT-PCR) testing will be enrolled in this study. Written informed consent will be ensured before participation. In case of no literacy, finger print will be considered for written permission.Consent will be sought from the legal guardian in case of minor or underaged.Formal ethical clearance will be taken from Ethical Review Committee (ERC) of Dhaka Medical College. All of the Participants will be divided into seven groups: Group A will receive Povidone iodine (PVP-I) nasal irrigation at concentration of 0.4%, Group B and Group C will received 0.5% and 0.6%; Group D will receive PVP-I nasal spray at concentration of 0.5% and Group E will received at 0.6% concentration. Group F (Placebo comparator group) will receive nasal irrigation by distilled water (DW) and Group G (Placebo comparator group) will received nasal spray by distilled water. The contact time will be minimum 30 seconds. After the individual application of PVP-I and distilled water in respective participant, they will be tested again for RT-PCR for COVID-19 from nasopharyngeal and oropharyngeal sample. All patients will be subjected to detail history, physical examination and adverse events. Block Randomization will be followed for randomization. Data will be recorded in a semi-structured questionnaire and will be analyzed by 'R-4.0.2' data analysis software
