This study is an extension of the randomized controlled trial NT-DFU-AFF-01 in which subjects were randomized to SOC for 12 weeks or SOC and fresh hypothermically stored human amniotic membrane (Affinity; fHSAM) for 12 weeks to determine if addition of fHSAM to SOC results in faster healing of Wagner grade 1 and 2 DFUs compared to SOC alone.
