Outcome Measures
Primary Outcomes (2)
Incidence and Severity of Adverse Events and Serious Adverse Events (Phase 1)
Incidence and severity of adverse events and serious adverse events evaluated at 24 weeks
24 Weeks
Change in Knee Pain (Phase 2)
Mean Change in WOMAC A Pain (Western Ontario and McMaster Universities Arthritis Index) score from Baseline to 12 weeks. 5-point Likert scale (0=none to 4=extreme). A negative difference constitutes a decrease in pain with a greater negative value indicating a greater reduction in pain.
Scored at Baseline and 20 Weeks
Secondary Outcomes (1)
Change in Knee Function (Phase 2)
Scored at Baseline and 20 Weeks
Study Arms (2)
AMPION™ 4 mL dose
EXPERIMENTAL4 mL injection of Ampion
Placebo 4 mL dose
PLACEBO COMPARATOR4 mL injection of placebo

Eligibility Criteria
You may qualify if:
- 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
- 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
You may not qualify if:
- 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 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)
- +6 more criteria
