NCT ID: NCT05265065 Active, not recruiting - COVID-19 Clinical Trials

Evaluation of Full Versus Fractional Dose of COVID-19 Vaccine Given as a Booster for the Prevention of COVID-19 in Adults in Mongolia.

Start date: May 27, 2022
Phase: Phase 3
Study type: Interventional

This clinical trial is a single-blind, randomised study to determine the reactogenicity and immunogenicity of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) vaccine (Pfizer-BioNTech) as booster dose in adults, who have previously received either Sinopharm (BBIBP-CorV®), AstraZeneca (ChAdOx1-S, or Vaxzevria®) or Sputnik V (Gam-COVID-Vac®) as their primary doses 6 to 9 months earlier. Both standard and fractional doses will be tested. Participants are healthy adults aged 18 years or older, with no upper age limit. Procedures will be implemented to ensure participants of all ages (aged 18 and above) are included and that there is an even age distribution (<50 and ≥50 years) in each group. There will be a total of 6 groups (Sinopharm-standard dose Pfizer, Sinopharm-fractional dose Pfizer, AstraZeneca-standard dose Pfizer, AstraZeneca-fractional dose Pfizer, Sputnik - standard dose Pfizer, Sputnik - fractional dose Pfizer), with 200 participants per group for Sinopharm and 100 for AstraZeneca and Sputnik.

NCT ID: NCT05096091 Active, not recruiting - COVID-19 Clinical Trials

International Study on COVID-19 Vaccine to Assess Immunogenicity, Reactogenicity and Efficacy (InVITE)

InVITE
Start date: August 16, 2021
Phase:
Study type: Observational

InVITE is funded by NIAID and is conducted in multiple international sites (approximately 20 sites across 7 countries). This is a study of adults who receive locally available COVID-19 vaccines through local vaccination programs. Persons will be enrolled within one day (before or after) of receipt of a COVID-19 vaccine. The study will enroll participants who receive COVID-19 vaccination at local clinics and/or study sites.

NCT ID: NCT04380532 Active, not recruiting - Covid19 Clinical Trials

Tableted COVID-19 Therapeutic Vaccine

COVID-19
Start date: May 15, 2020
Phase: Phase 1/Phase 2
Study type: Interventional

Safety and immunogenicity one-month study in healthy individuals administered once-daily pill of therapeutic vaccine made from heat-inactivated plasma from donors with COVID-19. Healthy, at least 20, volunteers will be monitored for signs of adverse events. Their PBMC will be collected at baseline and one month later to analyze which type of immune response vaccine has induced.

NCT ID: NCT01135056 Active, not recruiting - Clinical trials for Hepatocellular Carcinoma

Study to Compare Selective Internal Radiation Therapy (SIRT) Versus Sorafenib in Locally Advanced Hepatocellular Carcinoma (HCC)

SIRveNIB
Start date: July 2010
Phase: Phase 3
Study type: Interventional

The primary objective of this study is to assess the efficacy of SIRT as compared with Sorafenib in patients with locally advanced liver cancer in terms of overall survival (OS). The Study null hypothesis is, there is no difference in overall survival between patients receiving SIRT and those receiving Sorafenib therapy.
