The BASE-ACS randomized controlled trial : Key Findings at 60 months

At a 5-year follow up Titan2 bioactive stent was non inferior to Everolimus eluting stent for the primary endpoint of MACE (14.4% vs 17.8% p<0.001 for non inferiority).

The BASE-ACS randomized controlled trial : KEY FINDINGS AT 12 MONTHS

The clinical trial met its primary endpoint of MACE non-inferiority at 12 months. The TiTAN2 TiNO coated bioactive stent achieved a low 9.6% MACE rate compared to 9.0% for the control group and demonstrated its non inferiority versus Xience DES (p for non-inferiority = 0.001).

The TITAX-AMI Randomized Controlled Trial

The TITAX-AMI randomized controlled trial is a randomized controlled trial comparing the Titan2 bioactive (Stainless steel platform) stent against the leading 1st generation Drug-eluting stent TAXUS, from Boston Scientific in ACS (STEMI/NSTEMI) patients at 12 months and 60 months follow ups.

Randomized Controlled Studies versus Bare Metal Stents

At 14 days : Excellent Very early neointimal coverage of bioactive stents by optical coherence tomography

At an average of 14.5 days following stent implantation binary stent strut coverage was 96.3%. Based on data of the current report we can consider an even shorter (than 1 month) dual antiplatelet regiment following bioactive stent implantation.

At 2 months : The TiDES-OCT Randomized Trial: Early Vascular Healing after Titanium Nitride Oxide Coated Stent (bioactive stent) versus Everolimus Eluting Stent in patients with ACS

In this randomized controlled trial enrolling 40 patients, at a 2-month follow up neointimal stent strut coverage was nearly complete in the bioactive stent group (TiTAN OPTIMAX, Hexacath) versus the EES group (p<0.001).

At 9 months : BASE-ACS Trial OCT Substudy

The frequency of uncovered stent struts was significantly higher with EES than with bioactive stent (p<0.001) and stent strut malapposition was less common in the bioactive stent group 0.2% versus 4.6% for EES.

The OPTIMAX-OCT Randomized Controlled Trial

In this study 82 patients were randomized to receive either a bioactive stent TiTAN OPTIMAX or a SYNERGY everolimus eluting stent in ACS patients with a follow-up at 1 and 6 months. Bioactive stent strut coverage was faster and more complete compared to EES in patients with ACS.

BASE-ACS Sub-Study Long-Term Outcome in Diabetic Patients

Among 827 patients enrolled in the BASE-ACS Trial, 140 (16.9%) were diabetic. MACE trough 7 years was more frequent in diabetics versus non-diabetics (23.6% vs. 13.7% p=0.003). MACE was not statistically different between the two stent arms but lower in the bioactive stent group (18.5% versus 28%.)
