Deep Brain Stimulation Effects on Weight Change and Metabolic Rate
A study testing Deep Brain Stimulation of the Lateral Hypothalamic Area in people with Obesity, run by Allegheny Singer Research Institute (also known as Allegheny Health Network Research Institute) at 1 site in United States.
Trial summary
This study focuses on lateral hypothalamic area (LHA) deep brain stimulation (DBS) for severe obesity. In a previous pilot study, three subjects were implanted with a DBS electrode into the LHA under an Investigational Device Exemption (IDE) and IRB approved study at West Virginia University.

About this study
Official title: Effects of Deep Brain Stimulation of the Lateral Hypothalamic Area on Weight Change and Metabolic Rate
This study focuses on lateral hypothalamic area (LHA) deep brain stimulation (DBS) for severe obesity. In a previous pilot study, three subjects were implanted with a DBS electrode into the LHA under an Investigational Device Exemption (IDE) and IRB approved study at West Virginia University. That study demonstrated the safety of DBS of the LHA in these patients. These patients, who met the enrollment criteria of having prior placement of LHA DBS in accordance with previous study protocol, were eligible for this study with a goal of determining optimal DBS settings.
Read the detailed description
The goal of this study was to investigate changes in Resting Metabolic Rate (RMR) at different settings during stimulation of the LHA with DBS and to find the optimal setting for increasing the RMR in two patients that previously were implanted. Although 3 subjects had undergone placement of the DBS electrode in the pilot study, one subject was withdrawn from this study due to a lead breakage and medical instability pertaining to an unrelated abdominal infection.
Each subject utilized the metabolic chambers and Deltatrac II Metabolic Carts (SensorMedics Corporation, Anaheim, California or Datex-Ohmeda, Helsinki, Finland) at Pennington Biomedical Research Center (PBRC), in Baton Rouge, Louisiana to objectively measure the correlation of their metabolic rate to various novel settings on the DBS for a one week period.
The schedule for the metabolic testing included: Day 0 baseline overnight chamber with no stimulation. Days 1-4 Resting metabolic rate (RMR) will be performed hourly with variable LHS DBS settings. The settings will be changed approximately every 15 minutes after the DBS settings are changed. Day 4 overnight chamber at ideal metabolic rate setting. After RMR test on Day 4, the subject will have a dual-energy x-ray absorptiometry (DXA) scan performed to assess body composition.
Subjects were also be seen in clinic as often as every month but no less than every 3 months to assess changes in weight until the study ended.

| DBS of the Lateral Hypothalamic Area | Experimental | Single Arm: Deep Brain Stimulation of LHA for maximum RMR On days 1-4, subjects stayed in the inpatient unit to have metabolic weight, temperature, and resting metabolic rate (RMR) measured at different settings.
Metabolic testing RMR measurement: A clear plastic hood was placed over the head and chest Oxygen intake and carbon dioxide out-put were measured to determine how many calories were burned during the next 15-30 minutes. Each hour for the next seven hours, DBS settings were changed and the above process was repeated. On Day 4, a DXA scan was performed to assess body composition. Primary endpoint is the determination of optimal settings Receives: Device: Deep Brain Stimulation of the Lateral Hypothalamic Area |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Metabolic Rate

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Metabolic Rate (time frame: One week of testing for each subject.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01933113, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Oct 2025; AzTrials last refreshed its copy on 6 Nov 2026.
