Safety and Feasibility Study of Methylene Blue Photodynamic Therapy to Sterilize Deep Tissue Abscess Cavities

Kurzzusammenfassung

The objectives of this Phase 1 study are to evaluate the safety and feasibility of methylene-blue-mediated photodynamic therapy (MB-PDT) performed at the time of abscess drainage to treat deep tissue abscesses. Safety will be evaluated by physical examination and imaging and laboratory studies in order to identify adverse events that may be induced by MB-PDT. We hypothesize that MB-PDT will be a safe and feasible intervention for this patient population. Optical measurements will additionally be performed at the abscess wall to determine optical properties and methylene blue uptake.
