Hello @aljohnson1949, I would like to add my welcome to Connect along with @frankmoore and others. I haven't seen any specific clinical trials for large fiber neuropathy. The Foundation for Peripheral Neuropathy has some information on clinical trials and a link to search if you want to check it out - https://www.foundationforpn.org/clinical-trials/.

Are you dealing with neuropathy pain symptoms? Have you looked into any complementary or alternative therapies?
