Trigeminal Neuralgia: Noema Pharma, a Swiss-based clinical-stage company targeting orphan central nervous system (CNS) diseases, today announces the U.S. Food and Drug Administration (FDA) has authorized an Investigational New Drug (IND) application to initiate a Phase 2b clinical trial of the mGluR5 inihibitor NOE-101 in trigeminal neuralgia (TN).

The LibraTN trial is a multi-center, 24-week, prospective, double-blind, randomized withdrawal, placebo-controlled study to evaluate the efficacy and safety of NOE-101 in adults with pain associated with TN. NOE-101 has previously been found to be safe and well-tolerated in adult subjects. The LibraTN trial is expected to report in H1 2024.

“Severe neuropathic pain of the face can be excruciating and is often resistant to available treatments,” said Allison S. Feldman, Chief Executive Officer of the Facial Pain Association. “Typically anticonvulsants have been used to treat TN, but these drugs are not always well-tolerated and need to be carefully titrated. NOE-101’s promising safety profile and mechanism of action are encouraging signs that its clinical development could provide alternative treatments for those living with TN who currently have little or no options.”

Trigeminal neuralgia also called “tic douloureux”, is a chronic pain condition that affects the trigeminal nerve, which carries sensation from the face to the brain.

Trigeminal neuralgia is a form of neuropathic pain, associated with nerve injury or nerve lesion. New cases affect 4 to 5 of every 100,000 people in the United States each year. NOE-101 is a highly selective, potent, and cell-penetrant negative allosteric modulator of mGlu5 receptors for the management of pain associated with TN. It was effective in controlling pain in animal models of neuropathic pain.

“The antinociceptive effect of NOE-101 is explained by its unique chemical and physical properties and its ability to block nuclear membrane mGlu5 receptors, the receptors overexpressed in chronic pain,” said George Garibaldi, Chief Medical Officer of Noema Pharma. “Its efficacy is similar to the gold standard achieved by morphine and the non-opiate duloxetine, but with significant potential advantages in terms of side-effects and tolerance. The LibraTN study will help us gain further understanding of the efficacy of NOE-101 in patients with Trigeminal neuralgia-associated pain.”
