Vascular DynamicsVascular Dynamics said today that the FDA approved an investigational device exemption for a clinical trial of its MobiusHD device for treating resistant hypertension.

MobiusHD is designed to help regulate blood pressure using electrodes implanted in the carotid artery to stimulate baroreceptors there.

Mountain View, Calif.–based Vascular Dynamics said the 300-patient Calm 2 study is designed to compare treatment with MobiusHD and a sham procedure. The primary safety endpoint is a composite of death, myocardial infarction, stroke, device embolization, carotid occlusion, new ipsilateral carotid stenosis requiring surgical or percutaneous intervention, or Bleeding Academic Research Consortium 3 or 5 bleeding events at 90 days. The primary effectiveness endpoint is change in mean 24-hour ambulatory systolic blood pressure at 180 days, according to ClinicalTrials.gov.
