  • Moderate to severe pain in the index knee associated with OA must be stable for a minimum of 2 months prior to Screening, as assessed by the Investigator.
  • A specified mean pain score in the index knee over the 7 days prior to dosing, based on question A1 of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC A1).
  • Specified baseline and screening scores on the WOMAC A1
  • Body Mass Index ≤ 45 kg/m
  • Subjects must have had a therapeutic failure (no relief, or inadequate relief), and/or AEs resulting in stopping treatment, and/or contraindication to the standard of care appropriate to the severity of the index knee OA pain they are experiencing.

排除标准

  • Joint replacement surgery of the index knee at any time, or open surgery of the index knee in the past 12 months.
  • Prior arthroscopic surgery of the index knee within 3 months of Screening.
  • Any painful conditions of the index knee due to joint disease other than OA.
  • Mild pain in the non-index knee when walking.
  • Other chronic pain anywhere in the body that requires the use of analgesic medications.
  • Secondary OA of the index knee due to acute traumatic injury.
  • Significant current or past instability (e.g., cruciate ligament tear or rupture or previous repair) or misalignment (> 10 degrees varus or valgus) of the index knee
  • Has used topical capsaicin on the index knee within 90 days of Screening.
  • Corticosteroid injection in the index knee within 90 days of Screening.
  • Received IA viscosupplementation (e.g., Synvisc®, Hyalgan®) within 90 days of Screening.
  • Prior participation in an ALGRX 4975 or CNTX-4975 study.
  • Has any of the following characteristics:
  • active or historic substance use disorder within the previous year as defined by the Diagnostic and Statistical Manual for Mental Health Disorders, fifth edition, or
