Clinical Trials

The MiStent SES has received CE marking but is not approved in the USA or any other countries.
The following clinical trials are currently in long term follow-up. The 2 year follow-up for both trials was completed in 2013.

DESSOLVE I Clinical Trial

Micell has an ongoing clinical study, DESSOLVE I in New Zealand, Australia and Belgium. DESSOLVE I (MiStent SES with sirolimus and an absorbable polymer for the treatment of patients with de novo lesions in the native coronary arteries), a first-in-human clinical trial of the company's investigational MiStent® Sirolimus Eluting Absorbable Polymer Coronary Stent System (MiStent SES).

DESSOLVE I is a prospective, open-label, non-randomized, single-arm study that has enrolled 30 patients at five clinical sites in Belgium, Australia and New Zealand. Candidates for the trial had documented stable or unstable angina pectoris or ischemia. The primary endpoint, in-stent late lumen loss, was measured with angiography in treated de novo lesions ranging in diameter from 2.5 to 3.5 mm and amenable to treatment with a maximum 23 mm long stent.

Along with secondary clinical endpoints such as major adverse cardiac events and revascularization rates, intravascular ultrasound (IVUS) and optical coherence tomography (OCT) were also employed at multiple time points. The DESSOLVE I study used multiple imaging modalities to better understand the time to complete tissue coverage of the stent struts relative to polymer absorption.

DESSOLVE II Clinical Trial

DESSOLVE II is a prospective, controlled, 2:1 unbalanced randomized, multi-center study consisting of 183 patients. Patients have been enrolled at 26 clinical sites in Europe and New Zealand. The trial includes patients with documented stable or unstable angina pectoris or ischemia. The primary endpoint is superiority of MiStent SES in minimizing in-stent late lumen loss at nine months, compared to Medtronic's Endeavor® DES, as measured with angiography in treated de novo lesions ranging in diameter from 2.5 to 3.5 mm and amenable to treatment with a maximum 30 mm long stent.

Along with secondary clinical endpoints such as major adverse cardiac events and revascularization rates, the extent of stent coverage and re-endothelialization, via optical coherence tomography (OCT), and endothelial function (vasomotor response) will be evaluated in a subgroup of patients at nine months. More information on the DESSOLVE II trial can be found here.
