Technically not correct. Most blinded, randomized controlled trials showed improvements in symptoms and timeline [1,2,3, among others], but they are generally underpowered and so many consider the results to be not compelling. All the headlines you may have read that ivermectin studies found no results are way overblow; science journalism has never been great to begin with, and now politics has thoroughly infected this so signal to noise on this question is terrible. Some better trials are underway now, so we'll see.
Not surprising, the patentable drug got a decent trial since pharma actually has a much bigger financial incentive there.
If that was true then how do you explain the fact that so far no study was able observe or reproduce that effect under a controlled environment?
