Actually there is plenty of evidence that Ivermectin is effective against the virus, including a recent meta-data study that concluded that it is robust when used early. Most of the early studies of both Ivermectin or HCQ were used during advanced stages of the disease where it is not very helpful. I suggest you look at the results in the Indian state of Uttar Pradesh where they have widely used Ivermectin as a prophylactic and early treatment and since then they have had almost no deaths from the virus with a population of over 200 million.
Like I said, a number of treatments will eventually be approved when they no longer need the emergency use authorization (which isn't possible when effective treatments are available). By then, it will be too late because of the push for the gene therapies.
