  • Comparing Surgical and Endovascular Arteriovenous Fistula Creation

    open to eligible people ages 18-99

    Patients with end-stage kidney disease (ESKD) who use hemodialysis to filter their blood require vascular access for the dialysis machine; the most common type of vascular access is called an arteriovenous fistula (AVF). The AVF is a direct connect between an artery and vein. Until recently, AVFs were only created through surgery that requires general anesthesia and opening up the skin. Now there are 2 FDA-approved devices designed to create AVFs using endovascular techniques (endoAVF), which means a device that goes through the skin instead of opening the skin up. Also patients are not required to be under general anesthesia, they can receive local anesthesia instead. Due to the relatively new approval of these devices, there is not a randomized study to compare the results of endoAVF versus surgAVF. This study is a pilot study for an eventually larger scale study to compare the results of endoAVF versus surgAVF. The study aims to determine what the proportion of patients seeking hemodialysis access could qualify for receiving either an endoAVF , surgAVF, or both. Patients who are screened for hemodialysis access must undergo a duplex ultrasound of the blood vessels in the arm to confirm correct sizing. If participants qualify for both procedures they will be randomized to either endoAVF or surgAVF and will track the clinical and patient-reported outcomes of each procedure. Our pilot study hopes to enroll 90 participants. Those outcomes will inform a larger scale study. If the potential participant chooses to abstain from participation in the randomized trial, preferring to decide the method of AVF creation, we will offer to them a chance to join an endoAVF/surgAVF registry that will track the clinical outcomes of the procedure via medical record monitoring.

  • Arteriovenous Vascular (AV) ACCESS Trial

    open to eligible people ages 60 years and up

    This study is to prospectively compare the effectiveness and safety of the two types of arteriovenous access placement (fistula or graft) in older adults with end stage kidney disease and multiple chronic conditions

  • Compare the Efficacy and Safety of the HAV With AVF in Female Patients With End-Stage Renal Disease Requiring Hemodialysis

    open to eligible females ages 18 years and up

    The goal of this clinical trial is to compare the number of catheter-free days (CFD) and the rate and severity of any dialysis access-related infections between the HAV and AVF groups over 12 months in patients with end-stage renal disease (ESRD) needing hemodialysis (HD). Participants will be stratified by location of the vascular access (forearm versus upper arm) and by type of AVF creation procedure planned by the surgeon at randomization (1-stage AVF versus 2-stage AVF). The comparator is an upper extremity arterio-venous fistula (AVF) for HD access surgically created per the institution's Standard of Care (SoC).

  • Transanastomotic Tube for Proximal Esophageal Atresia With Distal Tracheoesophageal Fistula Repair

    open to eligible people ages up to 6 months

    This trial will compare the effectiveness of two common surgical practices for Type C esophageal atresia repair: esophageal atresia (EA) with distal tracheoesophageal fistula (TEF). Infants with EA/TEF requiring surgical intervention will be recruited. Subjects will be randomized to either repair with or without transanstomotic tube (TT) during esophageal anastomosis creation. Primary outcome is symptomatic anastomotic stricture development requiring dilation within 12 months.

  • Human Acellular Vessel (HAV) With Fistulas as Conduits for Hemodialysis

    Sorry, in progress, not accepting new patients

    The main purpose of this study is to compare the Human Acellular Vessel (HAV) with arteriovenous fistula (AVF) when used for hemodialysis access

  • Outcome Analysis of POEM and Endoluminal Therapies

    Sorry, accepting new patients by invitation only

    Evaluation of current and newly developed endoluminal therapies in the management of Upper and Lower GI conditions.

  • Seeded Cells on Matrix Plug Treating Crohn's Perianal Fistulas (STOMP-II)

    Sorry, in progress, not accepting new patients

    A Phase II study to assess the safety and efficacy of AVB-114 in treatment of complex Crohn's perianal fistulas in subjects with quiescent rectal disease and whose fistula has failed to respond to biologic or conventional therapy. Combined remission of treated perianal fistula in the investigational treatment arm will be compared to a standard of care control arm. The study has 2 parts: Part 1: All required study visits for subjects who initially receive study treatment and those who receive standard of care therapy (control arm). Part 2: Subjects who are enrolled in the control arm may receive treatment with AVB-114 following week 36. Those subjects then will be followed as specified in the clinical protocol.
