WEX is developing a new class of non-opioid analgesics. The Company’s proprietary product is HalneuronTM (tetrdotoxin, TTX), a small molecule, has been shown to be a safe, non addictive, well-tolerated, possible alternative to opioids. HalneuronTM is a new class of analgesic with a novel mechanism of action. It is a highly selective sodium channel blocker that targets voltage gated sodium channels on neurons but not those on cardiomyocytes. It is known to block nerve impulses that conduct pain signals. A Phase III clinical trial on the treatment of cancer related pain using HalneuronTM has recently been completed. We are in the process of filing a NDS with Health Canada for marketing approval. HalneuronTM has also been studied in a completed Phase II trial for chemotherapy induced neuropathic pain (CINP) in the US. WEX has conducted 15 clinical trials with HalneuronTM, with more than 700 patients treated to date. HalneuronTM is non-narcotic, without the side effects of opioids. It is non-addictive and has shown no evidence of tolerance. Clinical trials have shown that HalneuronTM provides a long duration of analgesia after an initial course of treatment in moderate to severe neuropathic pain.
