Adynxx, a clinical-stage pharmaceutical company developing a first-in-class platform of therapeutics to address pain at its molecular roots, announced today that the first patient was dosed in a Phase 2 study of its lead investigational drug candidate for the prevention of post-surgical pain, AYX1.
The 90-patient, placebo-controlled study will evaluate the safety and efficacy of a single administration of AYX1 given prior to unilateral total knee arthroplasty (TKA) to reduce acute pain and to prevent the transition to persistent pain. The study will follow patients for 42 days, with a primary endpoint of pain with walking. Secondary and exploratory endpoints will include pain at rest, pain with knee range of motion, rate and extent of functional recovery, opioid consumption and safety assessments. Further details of the study can be found at www.clinicaltrials.gov.
"While many widely used pain therapies require repeat dosing for symptom amelioration, or require heavy dosing with associated side-effects to treat pain with movement, a single administration of AYX1 has the potential to block the development of pain before it begins," said Donald Manning , M.D., Ph.D., chief medical officer of Adynxx. "This study will evaluate AYX1's ability to reduce acute pain and prevent persistent pain, especially pain associated with movement, enabling patients to begin rehabilitation and resume other activities earlier."
