Detailed Description
A Randomized Study to Confirm the Efficacy of an Intra-Articular Injection of Ampion™ in Adults With Pain Due to Severe Osteoarthritis of the Knee
There will be a 7-day screening period for each subject followed by a 12-week participation period.
The primary trial objective is to evaluate the clinical efficacy of Ampion using the Outcome Measures in Rheumatology Clinical Trials and Osteoarthritis Research Society International (OMERACT-OARSI) (using the Western Ontario and McMaster Universities Arthritis Index (WOMAC) 3.1 Index and Patient's Global Assessment as assessments).
The secondary trial objectives are to evaluate the safety of a single intra-articular injection (4 mL) of Ampion.

Description
Inclusion Criteria:
- Able to provide written informed consent to participate in the study;
- Willing and able to comply with all study requirements and instructions of the site study staff;
- Must be ambulatory;
- Study knee must have a clinical diagnosis of osteoarthritis (OA) supported by radiological evidence (Kellgren Lawrence Grade IV) which is assessed locally (x-rays within the past 6 months of screening are acceptable);
- Moderate to moderately-severe OA pain in the study knee (rating of at least 1.5 on the WOMAC A, 5-point Likert Pain Subscale);
- Moderate to moderately-severe OA function in the study knee (rating of at least 1.5 on the WOMAC C, 5-point Likert Function Subscale);
- WOMAC A, 5-point Likert pain subscale <1.5 in the contralateral knee;
- Ability to discontinue non-steroidal anti-inflammatory drug (NSAID) use at Screening visit and/or 72 hours prior to the Baseline visit and for the duration of the clinical study (low-dose aspirin (81 mg) is allowed during the study);
- No analgesia (including acetaminophen) taken 24 hours prior to an efficacy measure;
- No known clinically significant liver abnormality (e.g. cirrhosis, transplant, etc.).
Exclusion Criteria:
- As a result of medical review and screening investigation, the Principal Investigator considers the subject unfit for the study
- 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
- Inflammatory or crystal arthropathies, acute fractures, history of aseptic necrosis or joint replacement in the affected knee, as assessed locally by the Principal Investigator
- Isolated patella femoral syndrome, also known as chondromalacia
- Any other disease or condition interfering with the free use and evaluation of the study knee for the duration of the trial (e.g. cancer, congenital defects, spine osteoarthritis)
- Major injury to the study knee within the 12 months prior to screening
- Severe hip osteoarthritis ipsilateral to the study knee
- Any pain that could interfere with the assessment of study 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 randomization or likely to be changed during the duration of the study
- Pregnancy or planning to become pregnant during the study
Use of the following medications:
- No intra-articular (IA) injected medications in the study knee during the study (or 12 weeks prior to Baseline).
- No analgesics containing opioids.
- NSAIDs are not permitted during the study; acetaminophen is available as a rescue medication during the study from the provided supply.
- No topical treatment on the study knee during the study
- No significant anticoagulant therapy (e.g. Heparin or Lovenox) during the study (treatment such as low-dose Aspirin (81 mg) and Plavix are allowed)
- No systemic treatments that may interfere with safety or efficacy assessments during the study
- No immunosuppressants
- No use of systemic or intra-articular corticosteroids
- No human albumin treatment in the 3 months before randomization or throughout the duration of the study

Using the Outcome Measures in Rheumatology Clinical Trials and Osteoarthritis Research Society International (OMERACT-OARSI) criteria of WOMAC A Pain subscore, WOMAC C Function subscore, and PGA as composite endpoints. A patient in this study will be considered a responder for the purpose of efficacy analysis if the following criteria are met: (1) demonstration of ≥ 50% improvement AND a 1.0-unit change in pain OR 1.0-unit change in function OR If the patient does not meet this criterion, then the patient must demonstrate at least 2 of the following:
