If we look at the secondary endpoints note that 3x as many died in the control group, 2.5x as many needed mechanical ventilation and one third more need to go to the ICU.

            Ivermectin   Control
  n         247          249
  Mech vent   4           10
  ICU         6            8
  Died        3           10

These may not have been primary endpoints and may not have been statistically significant but it does raise the question of whether they would have been significant had a larger sample size been used.
