Description of intervention(s) / exposure
Treatment: Drugs - XG004
Treatment: Drugs - Placebo
Experimental: A (XG004) - XG004 in two dose level (5% or 10%) will be applied to the targeted knee
Placebo comparator: B (Placebo) - Placebo in all cohorts will be applied to the targeted knee.
Treatment: Drugs: XG004
XG004 gel in two concentrations (5% and 10%) will be applied topically once-daily, twice-daily or three times daily in a designated area of the study knee.
Treatment: Drugs: Placebo
Placebo gel will be applied topically once-daily, twice-daily or three times daily in a designated area of the study knee.

Skin safety and irritability assessment will be conducted after topical application of investigational product. All skin reactions at the applications sites will be examined and scored as per Modified Berger/Bowman Scoring Scale.
Pain will be examined a 0-10 NRS (numerical rating scale) and higher scores mean a worse outcome.
