13 Clinical Trials for Various Conditions
The study will evaluate the long-term safety and efficacy of intravascular beta radiation therapy to treat coronary in-stent restenosis using the Beta-Cath(TM) 3.5F System; data will be collected retrospectively on patients treated with the Beta-Cath™ 3.5F System in routine clinical practice following FDA pre-market approval of the System. Outcomes will be reported up to 5 years following treatment.
A Prospective, Multicenter, Randomized, Two-Arm, Single-blind Superiority Trial to Evaluate the Safety and Efficacy of the MagicTouch™ Sirolimus- Coated Balloon in the Treatment of Coronary Drug-Eluting Stent In-Stent Restenosis. Subjects with prior DES implantation presenting with ISR lesions undergoing PCI will be randomized into two groups: treatment with the MagicTouch™ sirolimus-coated balloon or POBA on a 2:1 basis. Approximately 492 subjects will be enrolled in the randomized study in a maximum of 50 study sites located in the United States. The goal is to establish the safety and efficacy of the MagicTouch™ sirolimus- coated balloon in treatment of coronary in-stent restenosis (ISR).
To define the long-term incidence and frequency of ISR follow DES implantation. Compare the clinical presentation, treatment and intervention success among de novo coronary artery stenosis and DES ISR. Compare short- and long-term outcomes of de novo coronary artery stenosis and DES ISR, assessed by incidence of mortality, MACE, MI, and TLR/TVR at index hospitalization, 30 days, 6 months, 1 year, 3 years, and 5 years, if available.
This study aims to test the hypothesis that plaque composition differs within a stent between bare metal stents and drug eluting stents (DES). It is possible that a difference in plaque composition seen within a stent may be contributory to the late thrombotic events seen more frequently with DES.
BACKGROUD: Percutaneous coronary intervention (PCI) is increasingly used to treat unprotected left main coronary artery stenosis. Protected LM PCI is considered standard of care in most centers. OCT allows for precise determination of stent placement, stent expansion and apposition. The pattern of vessel healing can be very precisely studied if immediate post-stent implantation OCT/IVUS data is compared to the 6-month post-PCI interval. While OCT cannot be optimally used for ostial lesion imaging, IVUS can be used to image ostial lesions/stent placement. Optimal and consistent vessel healing is particularly important in LM PCI where stent thrombosis is a potential complication with serious adverse outcome. HYPOTHESIS: Due to the absorption of the polymer of the Boston Scientific Synergy Stent over time, early strut coverage patterns and timeline may be different than previously observed in DES and BMS stents in LM PCI. Late acquired stent malapposition (LASM) is expected to differ from previous observations with traditional DES/BMS. Stent coverage in LM PCI will be studied with OCT or IVUS at six and 12 months and compared to OCT or IVUS at the time of stent implantation. OCT/IVUS data will be analyzed in a core lab (CRF) and correlated with clinical outcomes at 6 and 12 months.
The objective of this study is to evaluate the safety and effectiveness of the TAXUS Express2 Paclitaxel-Eluting Coronary Stent System as compared to brachytherapy in patients experiencing in-stent restenosis.
The objective of this study is to evaluate safety and effectiveness of the Lacrosse NSE ALPHA coronary dilatation catheter during PCI in subjects with stenotic coronary arteries.
Prospective, multi-center, randomized, single blind, controlled, noninferiority clinical trial. Subjects with previous bare-metal stent (BMS) or DES and qualifying evidence for ISR will be screened per the protocol inclusion and exclusion criteria. Eligible subjects will be randomized 1:1 to treatment with either the SELUTION SLR™ 014 DEB or SOC to include contemporary DES (zotarolimus-eluting stents \[ZES\] and everolimus-eluting stents \[EES\] only) or BA. A maximum of 20% of patients randomized to SOC will be treated with BA. The primary endpoint will be Target Lesion Failure (TLF) at 12-months in the SOC group vs. the SELUTION SLR™ 014 DEB in all patients.
The main objective of this study is to demonstrate the superiority or non-inferiority of the sirolimus-eluting Bx VELOCITY® stent compared to intravascular brachytherapy in patients with in-stent restenotic native coronary artery lesions.
This trial will treat patients with a new chemotherapeutic medicine who have undergone a successful and uncomplicated de novo stent placement in up to two native coronary arteries. The purpose of the trial is to determine the appropriate dose of the new medicine for future trials and to evaluate the incidence of treatment-emergent adverse events and serious adverse events.
In this replication study at the Cleveland Clinic, we seek to collaborate to validate findings of the CardioGene Study in an independent cohort of patients who have undergone bare metallic stenting.
This research study is intended to evaluate the safety and effectiveness of 3 different doses of BO-653, an investigational inhibitor of LDL cholesterol oxidation, when given orally twice a day compared to placebo (an inactive substance) in preventing restenosis (closure of vessel) within six months after stent implantation. Patients must be enrolled into this study within 24 hours after the stenting procedure. Additionally, over a 1- to 9-month post-stent period, the study will compare the safety and effectiveness of BO-653 versus placebo for measures of coronary artery vessel size by quantitative coronary angiography, major adverse cardiac events, and effects on the oxidative status of plasma lipids and other plasma components.
This trial will compare the long term safety and effectiveness of the V Flex Plus PTX Drug Eluting coronary stent with conventional treatment for in-stent restenosis for coronary arteries.
