  • No analgesia taken 24 hours before efficacy measure.

Exclusion

  • As a result of medical review and screening investigation, the Principal Investigator considers the subject unfit for the study.
  • Previous Ampion™ injection in the index knee.
  • Known clinically significant liver abnormality (e.g., cirrhosis, transplant, etc).
  • A history of allergic reactions to human albumin (reaction to non-human albumin such as egg albumin is not an exclusion criterion).
  • A history of allergic reactions to excipients in 5% human albumin (N-acetyltryptophan, sodium caprylate).
  • Presence of tense effusions in the index knee.
  • Inflammatory or crystal arthropathies, acute fractures, history of aseptic necrosis or joint replacement in the index knee, as assessed locally by the Principal Investigator.
  • Isolated patella femoral syndrome, also known as chondromalacia, in the index knee.
  • Any other disease or condition interfering with the free use and evaluation of the index knee for the duration of the trial (e.g., cancer, congenital defects, spine OA).
  • Major injury to the index knee within the 12 months prior to screening.
  • Severe hip OA ipsilateral to the index knee.
  • Any pain that could interfere with the assessment of index knee pain (e.g., pain in any other part of the lower extremities, pain radiating to the knee).
  • Any pharmacological or non-pharmacological treatment targeting OA started or changed during the 4 weeks prior to treatment or likely to be changed during the duration of the study.
  • Use of the following medications are exclusionary:
  • IA injected pain medications in the study knee during the study;
  • Analgesics containing opioids. NSAIDs may be continued at levels preceding the study and acetaminophen is available as a rescue medication during the study from the provided supply;
  • Topical treatment on osteoarthritis index knee during the study;
  • Significant anticoagulant therapy (e.g., Heparin or Lovenox) during the study (treatment such as Aspirin and Plavix are allowed);
  • Systemic treatments that may interfere with safety or efficacy assessments during the study;
  • Immunosuppressants;
