Promus PREMIER Below The Knee Registry

Status Recruiting

Clinical Trial Summary

The Promus Premier below-the-knee (BTK) drug-eluting stent (DES) is specifically designed to improve BTK vessel patency rates using a platinum-chromium alloy based stent that elutes the anti-restenotic drug everolimus to inhibit neo-intimal hyperplasia. Although DES stents are considered standard of care for certain BTK lesions, there is a paucity of data on the use of DES in the contemporary BTK chronic limb threatening ischemia (CLTI) population, especially in Singapore. The aim of the Promus PREMIER BTK registry is to collect one year data of the Boston Scientific Promus PREMIER BTK DES in BTK lesions in CLTI patients.

Clinical Trial Description

Peripheral arterial disease (PAD) is an atherosclerotic condition in which chronic inflammation of the arteries may result in CLTI and ultimately limb loss without treatment. This problem is likely to worsen with the increasing global prevalence of diabetes. The arterial blockage for diabetic CLTI patients occur predominantly in the BTK arteries which are challenging to treat effectively due to the high incidence of elastic recoil and high stenosis rates after plain old balloon angioplasty (POBA) of these often calcified lesions. The additional use of BTK drug-coated balloons (DCBs) have also not demonstrated any significant improvements compared to POBA. The Boston Scientific Promus Premier BTK DES is a next generation DES specifically designed to improve BTK vessel patency using a platinum-chromium alloy-based stent that elutes everolimus. It is made with the most radiopaque biocompatible alloy available with superior axial strength, exceptional conformability, maximum fracture resistance, higher radial strength and less recoil compared to cobalt alloy stent. It also has the highest labelled post-dilatation limits compared to other stents, providing clinicians with more flexibility during procedures. Subjects will be followed up at 1 month, 3 month, 6 month and 12 month post-intervention to assess primary and secondary efficacy and safety. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
