   systemic hypertension and/or respiratory distress syndrome;

   - Has open and/or non-healing wounds in the chest, abdomen and pelvis;

   - Has other systemic vascular abnormalities associated with neovascularization, such as
   macular degeneration, that in the opinion of the investigator could significantly
   affect the ability to evaluate the effects of BR55;

   - Is participating in a clinical trial or has participated in another trial with an
   investigational compound within the past 30 days prior to enrolment;

   - Has previously been enrolled in and completed this study;

   - Has any known allergy to one or more of the ingredients of the IP or to any other
