Hyperhidrosis is a tiny portion of the therapeutics market for botulinum toxin, so I don't think RVNC can justify the cost of running clinical trials in that indication. Daxxify will get some off-label sales for hyperhidrosis even without clinical data, as dewophile just said.
RVNC tested its (now discontinued) topical toxin formulation in hyperhidrosis, but the trial was a failure (#msg-119391369).
“The efficient-market hypothesis may be the foremost piece of B.S. ever promulgated in any area of human knowledge!”
