COVID19 Paid Clinical Trials in Arizona

A randomized, observer-blind, placebo-controlled immuno-bridging, and broadening study to demonstrate the equivalence of the immune response between participants enrolled in Phase 3 efficacy trial in India and demographically diverse healthy adult participants in the US which matched in age and vaccine formulation setting to whom those efficacy results are extrapolated; and to assess the broadening of the BBV152 in participants who previously received two shots of messenger ribonucleic acid (mRNA) COVID-19 vaccine at least 6 months earlier or one-shots of viral vector J&J/Janssen COVID-19 vaccine at least 2 months earlier. Safety and tolerability evaluation is a secondary endpoint. Read Less

This study is an open-label, single-arm study to evaluate the safety and efficacy of Astrostem-V, allogenic adipose tissue derived mesenchymal stem cells (AdMSC), in patients with COVID-19 pneumonia. After each subject completes 12-Weeks visit (Visit 12) and the data management team confirms all individual data have no issue, the individual database will be locked and the blinding will be open for the statistical analysis.

This is a multi-center, randomized, triple-blind, placebo-controlled (RCT) study to evaluate the efficacy and safety of Dapsone in older adults, and/or in adult patients (≥40yrs of age) with at least one high-risk comorbidity, among those with confirmed SARS-CoV-2 infection. 3000 infected patients diagnosed with COVID-19, non-hospitalized at the time of enrollment, meeting all inclusion and no exclusion criteria will be randomized (1:1 allocation ratio) to receive either Dapsone or placebo tablets for 21 days, and will be followed up for 7 days after treatment termination for outcome assessment and up to 30 days for safety monitoring.

Viruses are a major health problem for the general public and at risk populations. Normally, detection of antibody titers is the gold standard for determining the effectiveness of the immune system following natural or vaccine caused immunization. However, determining the effectiveness of other parts of the immune system are less common due to the difficulties with testing. Furthermore, there is a critical need to address other therapies in case vaccination is not successful in immuncompromised populations. Exercise has been shown to increase the strength of the immune system against many types of viruses and therefore could be simple way to improve immunity against the COVID-19 virus. The aim of this research is to determine the effects of exercise on anti-viral immunity against many types of common viruses before and after vaccination. We hypothesize that exercise will enhance the anti-viral immunity before and after vaccination. Up to 30 healthy volunteers (age 18-44 years) will be recruited to participate in this study. For completion of Aim 1, three visits are needed totaling around 7 hours of the patient's time and for Aim 2, three visits are needed totaling around 4.5 hours of the patient's time. The initial visit will be for pre-screening and if deemed healthy enough to participate, an exercise test to determine the VO2 max of the participant will be conducted. The following visits will require a trained phlebotomist to insert an in-dwelling catheter and participants will undergo a 20-minute incremental exercise trial. Approximately 50mL of blood will be collected at four different timepoints: at rest, 60% VO2 max, 80% VO2 max, and 1-hr post-exercise. All four collected blood samples will be used to expand viral specific T-cells and compare IFN-γ rele Read Less
