About this study

Official title: PEPCAD DES - Treatment of DES-In-Stent Restenosis With SeQuent® Please Paclitaxel Eluting PTCA Catheter

The aim of the study is to assess the efficacy of the Paclitaxel-eluting PTCA - balloon catheter SeQuent® Please to treat in-stent restenoses (ISR) of various drug eluting stents in native coronary arteries with reference diameters between 2.5 mm and ≤ 3.5 mm and lesion lengths ≤ 22 mm. The vessel patency following treatment with SeQuent® Please will be documented in ISR patients that have been treated with the Cypher® or Taxus® drug eluting stent.

Background information

Current treatments for In Stent Restenosis (ISR) are 'uncoated balloon only' angioplasty with conventional balloons (POBA), Bare Metal Stent (BMS) implantations, cutting balloons, rotablation and atherectomy. Their respective results to lower target vessel revascularizations were in part unsatisfactory and often conflicting. Also the temporary use of brachytherapy lead to late lumen loss (LLL) findings in the range from 0.22 ± 0.84 mm. Therefore, brachytherapy to treat ISR has also been abandoned because of the associated delayed endothelialization leading to late thrombosis.

The use of drug eluting stents (DES) to treat ISR lowered restenosis rates in the single digit range. Recently, the use of matrix coated paclitaxel-eluting PTCA balloon catheters (SeQuent® Please, Paccocath Technology®, Bayer/Schering \& B.Braun Melsungen AG) was compared to PES in the PEPCAD II trial which showed significantly lower 6-month LLL, 6-month MACE and TVR rates for SeQuent® Please (7.25%) as compared to PES for which the 12-month TVR rate was 19.0% and therefore in agreement with prior studies (ISAR DESIRE). Since these assessments were done in patients with BMS in-stent restenosis, it is of paramount interest to study in-stent restenosis of failed DES implantations since they may cause continued chronic inflammatory responses caused by the non-bioabsorbable polymer in particular once the drug release has ceased.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing SeQuent® Please and SeQuent® II in people with In-Stent Restenosis, run by Klinikum Coburg at 8 sites in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 32 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 20 May 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Late lumen loss (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00998439, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 May 2011.
