Wex Pharmaceuticals Inc. Commences Its Quantitative Sensory Testing Clinical Trial Evaluating the Impact of Halneuron(R) on Healthy Volunteers’ Sensory Perceptions

VANCOUVER, BC / ACCESSWIRE / December 11, 2023 / WEX Pharmaceuticals Inc. (“WEX” or the “Company”), a biotechnology company developing Halneuron^® (Tetrodotoxin or TTX) for pain, announced that it has commenced its Quantitative Sensory Testing (QST) clinical trial and is actively recruiting participants into this clinical trial. The QST clinical trial is being conducted in the Netherlands on 25 healthy volunteers, where each volunteer will receive two different doses of Halneuron. The primary objective is to evaluate the effect on the peripheral nervous system when different doses of TTX are administered to healthy volunteers. Sensitivity and pain from cold, heat, touch, vibration, and smell will be assessed.

Mr. Walter Korz, Chief Executive Officer of WEX says, “Quantifying the impact of TTX on a healthy person’s sensory perceptions will help us further understand how and why TTX uniquely relieves pain differently from common pain therapies used today. The QST clinical trial will also help us to better understand how TTX can be used in a more personalized manner to enhance its effectiveness for pain management.”

This is the first time Halneuron® will be evaluated in Europe. WEX has received EMA approval to conduct this clinical trial including obtaining necessary permits to import Halneuron into Europe.

About Quantitative Sensory Testing (QST)

QST is a sensitive, validated measure for peripheral sensory nervous function. The QST clinical trial involves stimulating a person’s skin with quantified sensory stimuli to determine thresholds and other changes in their sensory perception and sensory function. Heat and cold responses provide information about the function of thinly myelinated Aδ nerve fibers, light touch and vibration responses provide information about large myelinated Aβ nerve fibers, and a pain response indicates an impact on unmyelinated C fibers.

About Halneuron^®

Halneuron^® (TTX, Tetrodotoxin), a selective sodium channel blocker, produces analgesia either by decreasing the propagation of action potentials by sodium channels and/or by blocking ectopic discharges associated with chronic pain. Halneuron^® is an injectable formulation of Tetrodotoxin, a novel small molecule with action exclusively on the peripheral nervous system. Halneuron does not cross the blood-brain barrier and, therefore, is without the common side effects of euphoria, addiction, tolerance, sedation, and confusion experienced by opioids and other analgesics. Pharmacology studies revealed that TTX is a more potent analgesic than standard analgesic agents such as aspirin, morphine, or meperidine, with potential applications in many moderate to severe neuropathic pain conditions.
