COVID-19 Clinical Trials and Expanded Access

To ascertain globally the changes in the cytokines involved and TLRs/KIR activation in patients admitted to the hospital with a COVID-19 diagnosis, and the changes after initiation of the different therapies

The primary objective of this study is to establish differences in susceptibility to SARS CoV-2 infection among health care workers (HCW) highly exposed to patients with COVID-19 diagnosis. To ascertain this issue, we evaluated: - Changes in receptor polymorphism (ACE2 and CD26 receptor study. - SARS-CoV-2 CD4/CD8 T cell response (CTL) - Different KIR phenotypes

Study of the cause of lymphopenia in Covid19 viral infection will be done in 3 cohorts. First cohort will be patients asymptomatic or with mild symptoms. Second cohort will be patients with severe illness and admitted to ICU. Third cohort will be patients critically ill and on artificial ventilation.

This placebo-controlled clinical study is designed to evaluate the efficacy, safety and tolerability of administration of PH94B nasal spray four times per day as a treatment of Adjustment Disorder with Anxiety symptoms in adults. Subject participation in the Study will last a total of 6 to 10 weeks, depending on the duration of the screening period and whether they need a washout of concomitant anxiolytics. Upon signing an investigation review board approved informed consent, all subjects will complete Visit 1 (Screening) and enter a screening period lasting 7 to 35 days that could include taper of concomitant anxiolytics, if necessary. Screening visit will consist of safety assessments (medical history, physical examination, laboratory samples, electrocardiogram, urine drug screen, and urine pregnancy test [if appropriate]) and psychiatric assessments to determine eligibility. Subjects will then return to complete Visit 2 (Baseline). If the subject continues to meet inclusion and exclusion criteria, the subject will be randomized 1:1 to PH94B or placebo. Subjects will then commence 4 weeks of double-blind treatment with randomized investigational product (PH94B or placebo) four times per day. Subjects will return for weekly site visits (Visits 3, 4, 5, and 6), in which the subject will return the vial dispensed at the previous visit and receive a new vial, except at Visit 6 in which no new vial will be dispensed. Changes in AEs and concomitant medications will be collected. During these visits, psychiatric scales will be completed. When the subject returns for Visit 6, besides the assessments completed at Visits 3 through 5, the subjects will complete a brief physical examination, electrocardiogram, laboratory tests (chemistry and blood), and urinalysis. Any remaining IP vials will be collected. The subject will then come back after a one week washout period for Follow-up visit (Visit 7).

This is a dose-finding safety trial followed by a randomized pilot trial comparing administration of SARS-CoV2-specific T cells (SARS-CoVSTs) to standard of care treatment in hospitalized patients with COVID19 who are at high risk of requiring mechanical ventilation. The SARS-CoVSTs lines have been made at Baylor College of Medicine from healthy donors who have made a full recovery from COVID19. These cell lines were frozen for later use and will be thawed and used to treat patients who meet the eligibility criteria.

The aim of our study to compare the proportion of patients who develop SARS-CoV-2 disease in 3 groups: patients undergoing a abdominal ultrasound examination in a Specialty Center, patients undergoing endoscopic procedure in a third level hospital with CoronaVirus Disease (COVID-19) hospitalization plants and patients who make a telephonic visit (do not go to the hospital) in the digestive system service.

A phase 2/3 study to determine the efficacy, safety and immunogenicity of the candidate Coronavirus Disease (COVID-19) vaccine ChAdOx1 nCoV-19 in healthy UK volunteers.

Using Laser light to detect COVID 19 virus particles in deep throat swab / nasal swab samples.

Natural products with immunomodulation and antiviral activity showed a promising improvement in the outcomes of some viral infectious diseases both in preclinical and primitive clinical studies. The aim of this study is to utilize Saudi FDA licensed Nigella sativa (NS) seed oil towards improving disease outcomes in adult patients diagnosed with mild COVID-19. The study will be a prospective, open-label, non-randomized controlled pilot trial. Patients will be supplemented (add-on) with one capsule of black seed oil twice daily for 10 days. The primary outcome will be the proportion of patients who clinically recovered on day 14. The secondary outcomes will be clinical parameters and routine laboratory tests. If encouraging outcomes occurred, NS supplementation may be recommended as an add-on to standard care protocol to enhance the recovery from COVID-19 disease in the current emerging situation.

The objective of this study is to assess the long-term outcomes after hospital admission with Covid-19 with respect to pulmonary function, physical capacity, imaging, quality of life and socioeconomic outcomes.
