Phase

Phase

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Beta-cell Function After 52 Weeks of Therapy
Time Frame: Baseline (week -2) and 52 weeks
Treatment effect on beta-cell function as measured by the ratio of Week 52 arginine-stimulated insulin secretion during a hyperglycemic clamp(specifically, the incremental AUC of insulin with respect to basal value over a 10 min period [i.e., clamp time 290 min to 300 min]) to that at baseline (i.e., the ratio is calculated as arginine-stimulated insulin secretion at week 52 divided by arginine-stimulated insulin secretion at baseline [week -2]).
Baseline (week -2) and 52 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Beta-cell Function 4 Weeks After Cessation of Therapy
Time Frame: Baseline (week -2) and 56 weeks
Treatment effect on beta-cell function as measured by the ratio of Week 56 arginine-stimulated insulin secretion during a hyperglycemic clamp(specifically, the incremental AUC of insulin with respect to basal value over a 10 min period [i.e., clamp time 290 min to 300 min]) to that at baseline (i.e., the ratio is calculated as arginine-stimulated insulin secretion at week 56 divided by arginine-stimulated insulin secretion at baseline [week -2]).
Baseline (week -2) and 56 weeks
Change in First Phase C-peptide Release
Time Frame: baseline (week -2), 52 weeks, and 56 weeks
Ratio of first phase C-peptide response to glucose at 52 weeks (end of on-drug period) and 56 weeks (during off-drug period) compared to first phase C-peptide response to glucose at baseline (i.e., C-peptide response to glucose at week 52 or week 56 divided by C-peptide response to glucose at baseline [week -2]). C-peptide is measured as a surrogate marker of insulin secretion. First phase C-peptide/insulin release is measured during the first ten minutes of glucose infusion during a hyperglycemic clamp procedure.
baseline (week -2), 52 weeks, and 56 weeks
Change in Second Phase C-peptide Release
Time Frame: baseline (-2 weeks), 52 weeks, and 56 weeks
Ratio of second phase C-peptide response to glucose at 52 weeks (end of on-drug period) and 56 weeks (during off-drug period) compared to second phase C-peptide response to glucose at baseline (i.e., C-peptide response to glucose at week 52 or week 56 divided by C-peptide response to glucose at baseline [week -2]). C-peptide is measured as a surrogate marker of insulin secretion. Second phase C-peptide/insulin release is measured from time=10 minutes to time=80 minutes of glucose infusion during a hyperglycemic clamp procedure.
baseline (-2 weeks), 52 weeks, and 56 weeks
Change in Glycosylated Hemoglobin (HbA1c)
Time Frame: Week 0 and week 52
Change in HbA1c from week 0 to week 52 (i.e., HbA1c at week 52 minus HbA1c at week 0).
Week 0 and week 52
Change in Fasting Plasma Glucose
Time Frame: 0 weeks and 52 weeks
Change in fasting plasma glucose from week 0 to week 52 (i.e., fasting plasma glucose at week 52 minus fasting plasma glucose at week 0).
0 weeks and 52 weeks
Seven Point Self Monitored Blood Glucose (SMBG) Measurements
Time Frame: 0 weeks and 52 weeks
SMBG measured at 7 time points (before and after breakfast, before and after lunch, before and after dinner, at bedtime).
0 weeks and 52 weeks
Change in Body Weight
Time Frame: 0 weeks and 52 weeks
Change in body weight from week 0 to week 52 (i.e., body weight at week 52 minus body weight at week 0).
0 weeks and 52 weeks
M-value at Baseline, Week 52 and Week 56
Time Frame: baseline (week -2), 52 weeks, and 56 weeks
M-value at baseline (week -2), week 52 (end of on-drug period), and week 56 (during off-drug period). Insulin sensitivity was assessed during the euglycemic/hyperglycemic clamp test at baseline (week -2), week 52, and week 56. Insulin-mediated glucose uptake (M-value) was calculated as the mean glucose requirement during the 90-120 minute interval of the clamp.
baseline (week -2), 52 weeks, and 56 weeks
