or blood sugar levels that are outside of the normal range and hba1c level \> 8 is subsequently confirmed * any inflammatory skin condition over the target knee application area * use of any prohibited concomitant medications/therapies during the 7-day washout period or planned use of any prohibited concomitant medications/therapies during the 6 week treatment period * use of intraarticular or intramuscular steroids in the target knee within the previous 3 months or in any other joint within the previous 30 days * use of intraarticular hyaluronate in the target knee within the previous 6 months or in any other joint within the previous 30 days * current substance abuse or history of chronic substance abuse within the past year, or prior chronic substance abuse (including alcoholism and/or addiction to pain medications) that is determined at the discretion of the investigator as likely to interfere with trial assessments or recur during the trial * use of any systemic (oral or parenteral) corticosteroids within the prior month * uncontrolled psychiatric conditions (e.g., mania, depression, anxiety, substance dependence of any kind) that would impair the subject from safely participating in the trial, including completing any protocol requirements * evidence of cognitive impairment including dementia that may interfere with subject's ability to complete daily pain diaries requiring recall of average pain level in the past 24 hours * significant cardiovascular, respiratory, renal, hepatic, gastrointestinal, hematological or neurological disease or prior surgery that may interfere with the subject successfully completing the trial, including completing any protocol requirements as determined by the investigator * history of or known positive for hiv, hepatitis b surface antigen (hbsag) or antibodies to hepatitis c virus (hcv) * diagnosed with any form of cancer within the past 5 years, except for treated basal cell or squamous cell carcinoma of the skin * any other medical conditions, diseases or prior surgeries that in the opinion of the investigator would impair the subject from safely participating in the trial and/or completing any protocol requirements * active infection within 3 days of the baseline visit
