Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | BuMA Supreme Coronary Stent System (ITT) | The BuMA Supreme Biodegradable Drug Coated Coronary Stent System is a device / drug combination product consisting of a drug-coated balloon expandable stent and a rapid exchange delivery system. The cobalt chromium (CoCr) stent is coated with a very thin, non-erodable layer of poly n-butyl methacrylate (PBMA) that is covalently bonded to the metal surface through a proprietary electro-grafting (eG™) process. A topcoat is then applied that contains sirolimus, the active ingredient, embedded in a biodegradable polymer, poly lactic co-glycolic acid (PLGA). | 79 | 1,086 | EG000 |
| Group 2 | Durable Polymer EES (XIENCE or Promus DES) (ITT) | The control comparator is durable polymer everolimus-eluting stent systems (DP EES), consisting of the Xience™ family of durable polymer cobalt chromium everolimus-eluting coronary stent systems (Abbott Vascular, Santa Clara, CA, US), and the PROMUS Element™ family of everolimus-eluting coronary stent systems. | 41 | 543 | EG001 |
