BAE2 Trial Design

2Treatment groups
Active Control
Placebo Group
Group I: Bariatric Embolization ProcedureActive Control1 Intervention
27 subjects will be enrolled in the bariatric embolization(BM) procedure arm. BM procedure will be performed under moderate sedation. Procedure will take 1.5 hr to 3 hr subject will be placed on the X-ray fluoroscopy table. Radial or femoral vascular access will be achieved using a small gauge needle, dilated over a guidewire to accommodate a 5 French vascular sheath. Standard catheters, 3 dimensional imaging will be acquired of the stomach, the arteries supplying the fundus arising off the celiac vessel. Microcatheter into the left gastric and/or gastroepiploic arteries supplying the fundus and small calibrated spheres will be infused until stasis of anterograde arterial flow is achieved, with particular care to avoid infusion of non-target arteries. The left gastric and/or gastroepiploic arteries will be embolized. Repeat 3 dimensional imaging: assess bead distribution and fundal coverage. Subject will be monitored in the recovery room and will be observed overnight.
Group II: Control ArmPlacebo Group1 Intervention
27 participants enrolled in the procedure arm. Participants randomized to the control arm will follow the same screening. Pre-procedure assessment will take the same pre-procedure meds. Procedure day, interventional radiologist will determine radial or groin access. After the participant and procedure area are prepped, participants will be under standard moderate sedation medications; all participants will receive lidocaine & a skin nick to their groin or their wrist as determined by the operating physician. Participant will have a blind fold placed & their hearing damped either with ear plugs or noise cancelling headphones. Participants randomized to the control arm will not receive other procedural intervention. Procedural team will follow a prescribed simulated protocol. Participants randomized to the control arm will be given under skin lidocaine and receive a skin nick on the wrist or groin.

How many prior treatments have patients received?

Why did patients apply to this trial?

I've tried several dieting programs and they only work for a short time. I have been doing intermittent fasting for the last year or so. I cut back on sugar, dairy, and meat while increasing my fruit and vegetable intake, but I'm gaining weight.
PatientReceived no prior treatments
I want to feel healthy and improve my health. I’m hoping research/studies done today may help my children, my childrens’ children and others with any weight related issues/medical conditions.
PatientReceived 1 prior treatment
My dad just moved to Baltimore from Washington DC, I visit him often. I would like to lose weight for my family and my son. I'm tired of feeling tired all the time, running out of breath when we go on trips, and feeling like such a failure to myself and my son. This weight gain is affecting every aspect of my life and I want to take control.
