Assess the Efficacy of the Low Glucose Suspend (LGS) Feature in the MiniMed Paradigm® X54 System

Completed · Not applicable

Conditions studied: Type 1 Diabetes Mellitus

In brief

The purpose of this study is to assess the efficacy of the Low Glucose Suspend (LGS) feature in reducing hypoglycemia with the MiniMed Paradigm® X54 System with hypoglycemic induction from exercise. The study will consist of a total of 50 subjects, age 16 through 60 years with Type 1 Diabetes Mellitus.

Subject is pregnant or plans to become pregnant during the course of the study
Subject has a history of myocardial infarction, unstable angina, coronary artery bypass surgery, coronary artery stenting, transient ischemic attack, cerebrovascular accident, angina, congestive heart failure, ventricular rhythm disturbances or thromboembolic disease
Subject has active Graves disease
Subject with renal impairment or creatinine above the normal reference range (of the laboratory that the clinical site is utilizing), as demonstrated by the screening laboratory value
Subject is outside of the normal reference range (of the laboratory that the clinical site is utilizing) for hematocrit, as demonstrated by screening laboratory value
Subject is outside of the normal reference range (of the laboratory that the clinical site is utilizing) for potassium, as demonstrated by screening laboratory value
