NCT05279495

Brief Summary

Ultraviolet light A (UVA) causes oxidization of guanine to mutagenic 8-Oxoguanine (8-OxoG) and the most frequent and best characterized mutation in mitochondrial DNA (mtDNA), a deletion of 4,977 base pairs, called the "common deletion", a marker of photoaging.

Outcome Measures

Primary Outcomes (1)

  • Title: Double-Blind Study to measure and compare the Mean Percent Reduction UVA induced premutagenic and photoaging markers 8-oxo-dG and the common deletion in 20 subjects treated with CANNAXR and Vehicle and exposed to 3X their individual MED-UVA

    Determining the Efficacy of topically applied CANNAXR cream vs vehicle cream in decreasing UVA induced Premutagenic and Photoaging markers 8-oxo-dG and the common deletion in 20 subjects exposed to 3X their individual MED-UVA: Comparison of mean percent reduction in UVA induced 8-Oxo-DG and common deletion in CANNAXR and Vehicle treated skin and exposed to 3X MED-UVA

    2 weeks

Study Arms (1)

Masking Details
Subjects will receive sufficient CANNAXR cream (CANNAXR pods filled with CBD) and VEHICLE cream (cream with empty CANNAXR pods without CBD) in pump containers, marked right or left. Contents of pump containers unknown to subjects and investigators. All 20 subjects are treated with CANNAXR and Vehicle and the exposed to 3X their individual MED-UVA. The masking relates to which hip (right or left) of each individual receives which treatment, CANNAXR or Vehicle. Therefore there is masking of the treatments of all 20 subjects receiving both treatments, considered by clinicaltrial.gov a single arm study.
