Noema Pharma announces first patient dosed in Phase 2b LibraTN study of mGluR5 inhibitor NOE-101 in trigeminal neuralgia

  • Study evaluating the efficacy of NOE-101 for management of pain associated with trigeminal neuralgia

BASEL, Switzerland, February 22, 2022 Noema Pharma, a Swiss-based clinical stage company targeting orphan central nervous system diseases, today announces the dosing of its first patient in its Phase 2b clinical trial of the mGluR5 inihibitor NOE-101 in trigeminal neuralgia (TN).

LibraTN 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. LibraTN is expected to report in H1 2024.

TN, also called “tic douloureux”, is a chronic pain condition that affects the trigeminal nerve, which carries sensation from the face to the brain. TN is a form of neuropathic pain, associated with nerve injury or nerve lesion. New cases of TN affect 4 to 5 of every 100,000 people in the United States each year.

LibraTN is an excellent opportunity to evaluate a novel therapeutic option in patients with trigeminal neuralgia who are hoping for effective solutions to manage their excruciating pain,said Dr. Hossein Ansari, director of Facial Pain Clinic at Kaizen Brain Center, Associate professor of neurology at the University of California, San Diego, and principal investigator for the study. “LibraTN was designed in partnership with patients and, in addition to understanding the safety and efficacy of NOE-101, will address many questions that matter most for people with this painful condition. Trigeminal neuralgia, also known as the “suicide pain”, is a rare condition characterized by pain flares resembling electric shocks that attack one side of the face and is associated with a significant negative impact on patients functioning”.

“It’s very exciting to have dosed our first patient in this Phase 2b trial in trigeminal neuralgia. We see great potential for NOE-101 in pain management due to its ability to block the nuclear membrane mGlu5 receptors which are overexpressed in chronic pain,” said George Garibaldi, Chief Medical Officer of Noema Pharma. “Treatment options are scarce in TN with only one treatment option that was approved over 50 years ago. We believe that patients suffering from TN deserve the benefit of the latest mechanistic discoveries. NOE-101 has great potential to provide these patients with the efficacy they need and a safety profile compatible with long-term use.”

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 multiple animal models predictive of a therapeutic effect in neuropathic pain.
