The U of Minnesota trial[1] (they aim at recruiting 3000 people, currently 700-ish) will tell if there is any prophylactic effect or not when using hydroxychloroquine. As with remedesivir, the effect size is probably not very large (so no miracles) and thus a lot of patients are needed to determine if the effect is true or only random.
