  • Willing and able to comply with all study requirements and instructions of the site study staff
  • Male or female, 40 years to 85 years old (inclusive)
  • Ambulatory
  • Index knee must have been symptomatic for greater than 6 months with a clinical diagnosis of OA and supported by radiological evidence (Kellgren Lawrence Grade II-IV) acquired at Screening
  • Moderate to moderately severe OA pain in the index knee (rating of at least 1.5 on the WOMAC Pain Subscale) assessed at Screening and confirmed at randomization
  • Moderate to moderately severe OA pain in the index knee (even if chronic doses of nonsteroidal anti-inflammatory drugs \[NSAIDs\], which have not changed in the 4 weeks prior to Screening, had been used)
  • No analgesia taken 24 hours before efficacy measure

Exclusion

  • As a result of medical review and screening investigation, the Principal Investigator considered the subject unfit for the study
  • Previous Ampion injection
  • Known clinically significant liver abnormality (eg, cirrhosis, transplant, etc.)
  • History of allergic reactions to human albumin (reaction to non-human albumin such as egg albumin was not an exclusion criterion)
  • 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 (eg, 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 (eg, 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 any of the following medications:
  • IA-injected pain medications in the index knee during the study
  • Analgesics containing opioids (NSAIDs were allowed at the levels preceding the study and acetaminophen was available as rescue medication during the study from the provided supply)
  • Topical prescription treatment on the index knee during the study
  • Significant anticoagulant therapy (eg, heparin or enoxaparin) during the study (aspirin and clopidogrel were allowed)
  • Systemic treatments that could interfere with safety or efficacy assessments during the study
  • Immunosuppressants
  • Corticosteroids \>10 mg prednisolone equivalent per day or corticosteroids at doses ≤10 mg prednisolone equivalent that had been changed during the study
  • Any human albumin treatment in the 3 months before randomization
