@babse, Here's some older information that I posted in the Winsantor drug testing discussion here - https://connect.mayoclinic.org/discussion/winsantor-drug-testing/. The company is trying to get funding to enter phase 3 clinical trial. The drug is for diabetic neuropathy but there is some hope that it could help with other forms of neuropathy also.

"Treating Peripheral Neuropathy
The hope is that these new findings support the potential for select anti-muscarinic drugs already on the market, like pirenzepine, to be repurposed as a possible preventative, and even treatment, for the clinical effects of peripheral neuropathy, which, for patients, has been largely been a matter of pain relief, and associated with significant health care costs." --- Blocking Anti-Muscarinic Drugs May Reverse PN: https://winsantor.com/anti-muscarinic-drugs-may-reverse-peripheral-neuropathy/

WinSanTor’s lead compound, WST-057 is the topical containing pirenzepene - https://winsantor.com/pipeline/
