1.Primary Outcome
Title Measure the Concentration of Triamcinolone Acetonide (TA) in Blood Plasma
Hide Description

Plasma drug concentrations (pg/mL) by Time Point across FX006 and TAcs treatment arms in plasma.

For the PK analysis and individual concentration vs. time plots, a concentration that is BLOQ is assigned a value of zero if it occurs in a profile before the first measurable concentration. If a BLOQ value occurs after a measurable concentration in a profile and is followed by a value above the lower limit of quantification, then the BLOQ is treated as missing data. If a BLOQ value occurs at the end of the collection interval (after the last quantifiable concentration) it is set to zero. If two BLOQ values occur in succession after Cmax, the profile is deemed to have terminated at the first BLOQ value and any subsequent concentrations are set to zero for PK calculations

2.Primary Outcome
Title Incidence of Treatment Emergent Adverse Events
Hide Description

Safety analyses were conducted using the safety population.

Analyses of adverse events will be performed for those events that are considered treatment emergent, where treatment emergent is defined as any adverse event with onset after the administration of study medication in the first knee through the end of the study or any event that was present at baseline but worsened in intensity through the end of the study. Severity of Adverse events were graded by the Principal Investigator using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. The grading went from Grade 1 (Mild) to Grade 5 (Death related to AE).
