COVID-19 Clinical Trial
Official title:
Phase II Randomized Double Blind Clinical Trial Three Preventive Vaccine Formulations Consisting of Autologous Dendritic Cells and Lymphocytes Incubated With Different Quantities of Spike Protein Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), in Subjects Not Proven Actively Infected or Never Infected With COVID-19
This is a phase 2 randomized, double-blind clinical trial testing an anti-SARS-CoV-2 COVID-19 vaccine (AV-COVID-19) made on site using PT AIVITA Biomedika Indonesia's vaccine-enabling kit for the prevention of COVID-19 infection. The product is a subject-specific personal vaccine that consists of autologous dendritic cells and lymphocytes (DCL) previously incubated with a quantity of SARS-CoV-2 spike protein (S-protein) which was shown to be safe in a phase 1 study also conducted in Indonesia. In this phase 2 study, efficacy is assessed via enhanced S-protein-specific T-cell response by comparing results before and after vaccination. Safety is confirmed via laboratory values, observation and regular patient reporting.
In this phase 2 study, a single dose of AV-COVID-19 DCL vaccine is injected subcutaneously in the forearm (left or right) at week 0 (day-0), to facilitate inspection and avoid confusion of local post-injection reactions or shoulder pain. Follow-up visits to assess safety are performed at 1, 2, and 4 weeks after vaccination, with laboratory safety tests performed at weeks 1 and 4, and only at week 2 if any clinically significant changes at screening up to week 1. At each visit, the injection site is assessed, and the subject is asked about symptoms, and at weeks 0 (baseline before injection), 2 and 4, blood is drawn for immunogenicity testing. Reaction data at the injection site and safety profile are obtained by telephone to subjects on days 1, 2, and 3 after vaccine injection. Subjects are asked specifically about local injection site reactions and systemic flu-like symptoms (fever, chills, muscle aches, joint pain) for 7 days after injection. Adverse events (AE) are collected for 28 days after injection. Evaluation of laboratory tests for clinical safety parameters are carried out at screening as well as immediately before vaccination and on day 7 and day 28 post-vaccination. Serious adverse events (SAE), recent medical conditions, and other events requiring medical intervention are recorded for 2 months after vaccination. Vaccine enabling kits are made by PT AIVITA Biomedika Indonesia. All vaccines are made in Indonesia on site at participating hospitals and clinical sites. ;
