About this trial

This study investigates the potential of vericiguat, a soluble guanylate cyclase stimulator, to improve cardiometabolic health in obese Black individuals with insulin resistance by directly enhancing cyclic guanosine monophosphate (cGMP) activity. Given that this population has been shown to have lower cGMP activity and the association of lower cGMP activity with increased cardiometabolic disease risk, the proposed study hypothesizes that augmenting cGMP activity in obese individuals will improve insulin sensitivity and energy expenditure. This study is a placebo-controlled randomized trial involving 200 Black obese participants with insulin resistance, assessing the effects of vericiguat on insulin sensitivity, resting, and exercise-induced energy expenditure over 12 weeks. Additionally, it will explore changes in brown adipose tissue and gene expression related to energy metabolism in white adipose tissue, aiming to provide insights into how increasing cGMP activity may improve cardiometabolic health in Black obese individuals.

Design model

Parallel

Treatments tested in this trial

  • Vericiguat 10 MG

    Drug

    The subject will be randomized, in a double-blind manner to vericiguat 10 mg once daily for a period of 12 weeks.

  • Placebo

    Other intervention

    The subject will be randomized, in a double-blind manner to placebo once daily for a period of 12 weeks.

  • Insulin Sensitivity Test

    Other intervention

    An assessment of the insulin sensitivity will be done using the Euglycemic Hyperinsulinemic Clamp, at baseline and after 12 weeks of pharmacological interventions.

  • Resting Energy and Exercise Energy Expenditure Assessment

    Other intervention

    Each participant's Energy Expenditure will be determined using a metabolic cart, at baseline and after 12 weeks of pharmacological interventions.

  • White Adipose Tissue Biopsy

    Other intervention

    Participants who consent to participate in the exploratory aim will undergo WAT biopsy to assess UCP1 gene expression from the collected biospecimens, at baseline and after 12 weeks of pharmacological interventions.

  • MRI-PET Scan for Brown Adipose Tissue Volume Assessment

    Other intervention

    Participants who consent to participate in the exploratory aim will undergo PET/MR to BAT volume at baseline and after 12 weeks of pharmacological interventions.
