About this study
Official title: A Prospective Clinical Trial of the TANTALUS System In Treatment of Obese to Morbidly Obese Patients
The objectives of this feasibility study are to evaluate the safety and functionality of the TANTALUS System with TANTALUS II IPG, to assess the effect of GCM signal application on trends of HbA1c, blood glucose and body weight changes.
Read the detailed description
This is a prospective multi center, non-randomized, treatment only clinical trial with up to thirty (30) obese with type 2 diabetes subjects. The study is designed to demonstrate that use of the rechargeable TANTALUS II IPG is safe and that it functions as designed.
Subjects will undergo an approximately two week baseline screening process. Eligible subjects will undergo device implantation. This will be followed by therapy initiation approximately one week after implantation. The device will then be activated to automatically deliver gastric contractility modulating (GCM) for 12 weeks of therapy. Stimulation will continue in for a safety monitoring period of 18 months following the therapy period.

Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Safety Evaluation (time frame: June 2004-September2009). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 22 Sep 2016.
