In this study, participants will be randomly assigned (by chance, like flipping a coin) to receive the study drug or placebo. You will have a 50% (1 in 2) chance of receiving the study drug and a 50% (1 in 2) chance of receiving placebo. To make sure the results are not influenced by anyone, neither you nor the study team will know which group you are in, unless there is an urgent medical need.
