Outcome Measures
Primary Outcomes (3)
Change in minimal erythemal dose (MED) from baseline to day 60.
Baseline minimal erythemal dose (MED) measurements will will be compared to MED results at day 60. We will use the conventional definition of MED as the lowest UV dose resulting in erythema that completely fills the 8-mm irradiated site (homogeneous erythema).
Change from baseline to day 60
Change in concentration of prostaglandin E2 (PGE2) in plasma from baseline to day 60.
Baseline PGE2 levels in plasma specimens will be compared to PGE2 levels at day 60.
Change from baseline to day 60
Change in concentration of prostaglandin E2 (PGE2) in nevus tissue from baseline to day 60.
Baseline PGE2 levels in tissue specimens will be compared to PGE2 levels at day 60.
Change from baseline to day 60
Secondary Outcomes (4)
Change in concentration of oncometabolite 2-hydroxyglutarate (2-HG) in plasma from baseline to day 60.
Change from baseline to day 60
Change in concentration of 8-oxoguanine (8-OG) in plasma from baseline to day 60.
Change from baseline to day 60
Change in concentration of oncometabolite 2-hydroxyglutarate (2-HG) in nevus tissue from baseline to day 60.
Change from baseline to day 60
Change in concentration of 8-oxoguanine (8-OG) in nevus tissue from baseline to day 60.
Change from baseline to day 60
