详细说明

This is a multi-center, Phase 2, randomized, double-blind, placebo-controlled study to evaluate the safety and efficacy of AYX1 Injection administered intrathecally before surgery in patients undergoing primary unilateral total knee arthroplasty (TKA). Subjects will be randomized on the day of surgery to receive either intrathecal AYX1 Injection or intrathecal placebo just prior to surgery. Study assessments will be conducted during the inpatient period through 48 hours; follow-up visits will be performed through Study Day 90.

描述

Inclusion Criteria:

  • Scheduled to undergo primary unilateral TKA with spinal anesthesia for painful osteoarthritis without congenital knee pathology
  • American Society of Anesthesiologists Physical Status Classification System ≤ 3
  • Medically stable as determined by the Investigator based on pre-study medical history, physical examination, clinical laboratory tests, and 12-lead electrocardiogram (ECG) findings
  • Body Mass Index of 18-45 kg/m2
  • Stable medical regimen for at least 1 week before randomization
  • Able to read and understand study instructions in English, and willing and able to comply with all study procedures

Exclusion Criteria:

  • More than 2 other current focal areas of pain, any pain areas greater in intensity than the target knee, or any other active chronic pain conditions that would compromise operative knee pain evaluation
  • Inflammatory arthridities (e.g., rheumatoid arthritis, lupus, ankylosing spondylitis, psoriatic arthritis), with the exception of clinically stable/non-active gout that does not affect the knee and does not interfere with walking
  • Surgery in either knee within 3 months prior to randomization, or surgery in either knee greater than 3 months prior to randomization with residual symptoms that would interfere with post-TKA study assessments; use of cryoneurolysis (including Iovera) on the current operative knee region within the 6 months prior to randomization and/or at any time through the duration of the study
  • Planned use of general anesthesia or potent inhalational agents, peripheral nerve block (e.g., femoral nerve block), neuroaxial (intrathecal or epidural) opioids, preoperative extended release/long acting opioids, or any use of ketamine preoperatively and/or at any time through the duration of the study
  • Use of more than 40 mg per day (on average) of oral morphine or its equivalent within 1 month prior to randomization
  • Use of gabapentin or pregabalin within 1 week prior to randomization or planned use post-operatively through Day 28
  • Use of systemic corticosteroids (IV or oral) within 3 months prior to randomization through Day 28; planned use of intra-articular steroid injections in the operative knee from the time of randomization through Day 28
  • Current neurologic disorder, which could confound the assessment of pain (e.g., Parkinson's, Multiple Sclerosis)
  • Untreated or inadequately treated (in the opinion of the Investigator) active depression
  • Mini Mental State Exam score < 24 at screening
  • History of alcohol-related complications within 1 year of randomization including, but not limited to, alcoholic withdrawal seizures, hallucinations, delirium tremens or detoxification treatment
  • Known or suspected history of illicit drug use within 1 year before randomization, or current or planned use of marijuana (including medical approved use) within 1 month before randomization and/or through the duration of the study
  • Any confirmed malignancy within the past year, with the exception of basal cell carcinoma or uncomplicated or stable skin cancers documented to not require further or immediate treatment
  • Women who are pregnant or nursing
  • Previous participation in any study involving AYX1 Injection
