COVID19 Clinical Trials in Phoenix, AZ

The purpose of this clinical trial is to learn about the safety, extent of the side effects, and immune responses of the study vaccine (called variant-adapted BNT162b2 RNA-based vaccine) in healthy children. The trial is divided into 5 individual studies or substudies based on age group and prior history of COVID-19 vaccinations. All participants in each of the 5 sub-studies will receive study vaccine as a shot depending on what group they are in. Substudy A design: Phase 1 includes participants 6 months through less than 4 years 3 months of age who have not received a previous coronavirus vaccination (COVID-19 vaccine naïve) and will receive 3 doses of study vaccine as their initial series, followed by a fourth dose of study vaccine. Phase 2/3 includes participants 6 months through less than 5 years of age who have not received a previous coronavirus vaccination (COVID-19 vaccine naive) and will receive 1, 2, or 3 doses of study vaccine, depending on what group they are in. Substudy B design: includes participants 6 months through less than 5 years of age who have either received 2 or 3 prior doses of BNT162b2 and will receive study vaccine as their third or fourth dose. Substudy C design: Phase 1 includes participants 6 months through less than 5 years of age who have received 3 prior doses of BNT162b2 and will receive study vaccine as their fourth dose. Substudy D design: includes participants 5 through less than12 years of age who have received 2 or 3 prior doses of BNT162b2 and will receive study vaccine as their third or fourth dose. Substudy E design: includes participants 2 through less than 12 years of age who have not received a previous coronavirus vaccination (COVID-19 vaccine naive) and will receive a single dose of study vaccine.

Researchers are creating real-time epidemiology registry to evaluate the efficacy of COVID-19 subject risk assessment scores based on recording of symptoms, biomarkers, chronic illness and mental health assessments with digital technology using wearables and mobile app tools. Researchers aim to study in Phase 1, epidemiological variations in COVID-19 presentation in both PCR positive and negative subjects in the registry. Assessment of variables, predictive modeling of variables that impact severity of COVID-19 positive and negative subjects and assessment of predictors for post COVID-19 complications. In Phase 2, 2700 subjects with COVID-19 positive test will be studied in the intervention group comparing ECL-19 vs placebo with primary end point of hospital admission assessment. Treatment strategy for PCR positive COVID-19 subjects in the registry who are in Stage I of the disease process with ECL-19 drug compared to placebo in reducing hospital admissions 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.
