That's a much lower bar than most drug trials impose. Given the severity of the situation, trying anything that might work and isn't obviously worse than the disease makes sense right now. But equally, given the side effects of chloroquines and also the postulated mechanism of action for an antiparasitic against a virus being literally just "zinc stuff? idk lol ¯\_(ツ)_/¯" right now, I think it's no less reasonable to want to see some more rigorous evaluation before regarding it as the panacea it's been claimed in many quarters to be.
