NYX-2925 did not achieve the primary endpoint of the study
EVANSTON, IL, USA I April 07, 2022 I Aptinyx Inc. (Nasdaq: APTX), a clinical-stage biopharmaceutical company developing transformative therapies for the treatment of brain and nervous system disorders, today announced results from a Phase 2b clinical study evaluating the effects of NYX-2925 in patients with painful diabetic peripheral neuropathy (DPN). NYX-2925 did not achieve statistically significant separation from placebo on the study’s primary endpoint, which assessed the change from baseline in average daily pain on the numeric rating scale (NRS) during week 12.
“We are clearly disappointed that the study did not meet its primary endpoint,” said Andy Kidd, M.D., president and chief executive officer of Aptinyx. “We appreciate the contributions of patients, investigators, and the entire team that worked on the study. Unfortunately, the data from this study do not currently point to a path forward in development for painful DPN.”
“We continue to believe, however, that NYX-2925 can offer a novel therapeutic approach for fibromyalgia, a disorder fundamentally characterized by abnormal pain processing in the brain. To this end, we look forward to reporting data from our ongoing fibromyalgia Phase 2b study in early to mid Q3. We continue to have confidence in our platform and pipeline and will manage our existing balance sheet to enable readouts across our currently ongoing Phase 2 studies in fibromyalgia, cognitive impairment, and PTSD.”
The Phase 2b painful DPN study was a randomized, double-blind, placebo-controlled study designed to evaluate the efficacy and safety of NYX-2925 in 229 patients with advanced painful DPN. Following a screening period, eligible patients were randomized to receive oral doses of NYX-2925 50 mg or placebo once daily over the treatment period. The primary endpoint in the study was the change from baseline in average daily pain as reported on the zero-to-ten NRS during week 12 of the study. Additional pain endpoints included worst daily pain, pain on walking, and pain interference with sleep.
The primary endpoint of the study was not achieved. Patients receiving NYX-2925 showed an improvement in average daily pain scores, but separation from placebo was not observed. Separation between NYX-2925 and placebo was also not observed on the other pain endpoints. NYX-2925 was well tolerated in the study, with no concerning safety issues observed. Detailed data from the study continue to be evaluated.
About NYX-2925
NYX-2925 is an investigational, novel oral NMDA receptor positive allosteric modulator (PAM) in Phase 2b clinical development for the treatment of chronic pain. In clinical studies, NYX-2925 has demonstrated activity that affects central, supraspinal pain processing, resulting in alleviation of pain and other symptoms associated with specific chronic pain conditions. NYX-2925 has also exhibited a favorable safety and tolerability profile across a wide dose range in clinical studies to date.
About Neuropathic Pain and Painful Diabetic Peripheral Neuropathy
Neuropathic pain, associated with various conditions, affects an estimated 7% to 9% of the U.S. population. Individuals suffering from this condition, regardless of the underlying disorder, are currently treated with a variety of therapies including antidepressants, anticonvulsants, and opioids. These medications offer inadequate efficacy for a large proportion of patients, are often poorly tolerated due to side effects, and in some cases are associated with abuse.
Painful DPN is one of the largest neuropathic pain conditions. An estimated 8.5 million people in the United States suffer from this condition, which develops in 60% to 70% of people with diabetes when chronically high glucose levels damage nerves and impair transmission of information between the central nervous system and other parts of the body. Patients suffering from DPN may also experience sensory loss, leading to difficulties with balance, coordination, and walking.
