Prevention of Infection Disease Caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) Clinical Trial
Official title:
A Phase 1/2, Randomized, Observer-Blind, Placebo-Controlled Trial to Evaluate the Safety and Immunogenicity of TAK-019 by Intramuscular Injection in Healthy Japanese Male and Female Adults Aged 20 Years and Older (COVID-19)
TAK-019 is a vaccine in development to protect people against Covid-19. The main aims of the study are to learn if TAK-019 can protect people from Covid-19 and to check for side effects from TAK-019. At the first visit, the study doctor will check if each person can take part. Those who can take part will be chosen for 1 of 2 treatments by chance. Participants will either receive an injection of TAK-019 or a placebo in their arm. In this study, a placebo will look like the TAK-019 vaccine but will not have any medicine in it. 3 times as many participants will receive TAK-019 than placebo. Participants will receive 2 injections of TAK-019 or placebo, 21 days apart. Participants will be asked to record their temperature and any medical problems in an electronic diary for up to 7 days after each injection. During the study, participants will visit the clinic for regular check-ups, blood tests, and sometimes for nose swab samples. When all participants have attended a clinic visit 28 days after their 2nd injection, the study sponsor (Takeda) will check how many participants have made enough antibodies to protect them against Covid-19. The participants will stay in the study for up to 12 months after they have had their 2nd injection. During this time, the study doctors will continue to check how many participants have made enough antibodies to protect them against Covid-19. Also, they will check if participants have any more side effects from TAK-019 or the placebo.
The drug being tested in this study is called TAK-019. TAK-019 is being tested to prevent infectious disease caused by Severe Acute Respiratory Syndrome coronavirus-2 (SARS-CoV-2). This study will look at the evaluate the safety and immunogenicity of 2 doses of TAK-019 by intramuscular (IM) injection 21 days apart in healthy Japanese male and female adults. The study will enroll approximately 200 healthy volunteers. Participants will be randomly assigned (by chance, like flipping a coin) to one of the two treatment groups-which will remain undisclosed to the participant and study doctor during the study (unless there is an urgent medical need): - TAK-019 0.5 mL - Placebo- this is an injection that looks like the study drug but has no active ingredient All participants will be asked to take intramuscular injection in the upper arm twice throughout the study. This multi-center trial will be conducted in Japan. The overall time to participate in this study is 12 months from the second vaccination (totally 387 days). Participants will make multiple visits to the clinic and will be contacted by telephone or a final visit after the last vaccination for a follow-up assessment. ;
