Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - DIAMOND System

Experimental: Low blood TG patients - subjects with baseline blood triglyceride level = 1.7 mmol/l will have intervention device (DIAMOND Implantable Pulse Generator (IPG)) programmed to deliver GCM signal including the setting of automatic eating detection parameters for a 48 weeks period.

Experimental: High blood TG patients treated with blood TG lowering therapy - subjects with baseline blood triglyceride level \> 1.7 mmol/l will have their device programmed to deliver GCM signal including the setting of automatic eating detection parameters for a 48 weeks period and will receive fenofibrate at the dose of 160mg per day

Placebo comparator: High blood TG patients - subjects with baseline blood triglyceride level \> 1.7 mmol/l will have their device programmed to deliver GCM signal including the setting of automatic eating detection parameters for a 48 weeks period and will receive placebo of fenofibrate administered in the same schedule as the drug.

* Subjects with an EF less than 35% or otherwise indicated for an ICD
* Taking medications known to affect gastric motility such as narcotics (chronic use) and anticholinergics/antispasmodics
* Experiencing severe and progressing diabetic complications (i.e. retinopathy not stabilized, nephropathy with macroalbuminuria)
* Prior wound healing problems due to staphylococcus or candida
* Diagnosed with past or current psychiatric condition that may impair his or her ability to comply with the study procedures
