Conclusions

  • The Supraflex biodegradable polymer SES (sirolimus eluting stent) was non-inferior to the Xience durable polymer EES (everolimus-eluting stent) for DOCE at 12 months in an all-comer population with a lower rate of CI-TLR in the per-protocol analysis
  • In Per-Protocol analysis (only study stent used, no crossover to any other stent) Supraflex shows significant 61% relative reduction in CI-TLR as compared to Xience stent
  • No difference in Definite and Probable Stent Thrombosis between Supraflex and Xience
