Dose-ranging Study in Patients With Type 1 Diabetes Mellitus (inTandem4)

February 10, 2020 updated by: Lexicon Pharmaceuticals

A Phase 2b, Dose-ranging, Randomized, Double-blind, Placebo-controlled, Parallel-group, Multicenter Study in Patients With Type 1 Diabetes Mellitus Who Have Inadequate Glycemic Control With Insulin Therapy

The primary objective of this study was to define the dose leading to desirable efficacy, as measured by the change in hemoglobin A1C (A1C) between Baseline and Week 12.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics.

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.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Inclusion Criteria:

  • Participant had given written informed consent to participate in the study in accordance with local regulations.
  • Adult participants 18 years and older with a diagnosis of type 1 diabetes mellitus (T1D) made at least 1 year prior to informed consent.
  • Participants were being treated with insulin or insulin analog delivered via continuous subcutaneous insulin infusion (CSII) or multiple daily injection (MDI).
  • At the Screening Visit, A1C had to be between 7.0% and 10.0%.
  • Females of childbearing potential had to use an adequate method of contraception and have a negative pregnancy test.

Exclusion Criteria:

  • Use of antidiabetic agent other than insulin or insulin analog at the time of screening.
  • Use of sodium-glucose cotransporter (SGLT) inhibitors within 8 weeks prior to screening.

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
Change From Baseline in Hemoglobin A1C (A1C) at Week 12
Time Frame: Baseline to Week 12
Baseline was defined as the last value collected prior to the first dose of double-blind study medication. Post-baseline Least Square (LS) mean values were obtained from mixed-effects model repeated measures (MMRM) model with treatment, randomization strata of insulin delivery method (continuous subcutaneous insulin infusion [CSII] or multiple daily injection [MDI]), time (study week), and a treatment-by-time interaction as fixed categorical effects, and baseline A1C-by-time interaction as a covariate.
Baseline to Week 12

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
Change From Baseline to Week 12 in 2-Hour Postprandial Glucose (PPG) Following the Standardized Mixed Meal
Time Frame: Baseline, Week 12
A 2-hour PPG sample (plasma) was obtained 2-hours after a standardized Mixed Meal at Baseline (Day 1) and at the visit at Week 12. Post-Baseline LS mean was obtained from analysis of covariance (ANCOVA) model with treatment, randomization strata of insulin delivery method (CSII, MDI) as fixed categorical effects, and baseline postprandial glucose as a covariate.
Baseline, Week 12
Absolute Change From Baseline in Body Weight to Week 12
Time Frame: Baseline to Week 12
Baseline was defined as the last value collected prior to the first dose of double-blind study medication. Post-Baseline LS mean was obtained from MMRM model with treatment, randomization strata of insulin delivery method (CSII, MDI), time (study week), and a treatment-by-time interaction as fixed categorical effects, and baseline weight-by-time interaction as a covariate.
Baseline to Week 12
Percent Change From Baseline in Body Weight to Week 12
Time Frame: Baseline to Week 12
Baseline was defined as the last value collected prior to the first dose of double-blind study medication. Post-Baseline LS mean was obtained from MMRM model with treatment, randomization strata of insulin delivery method (CSII, MDI), time (study week), and a treatment-by-time interaction as fixed categorical effects, and baseline weight-by-time interaction as a covariate.
Baseline to Week 12
Change From Baseline to Week 12 in 24-Hour Urinary Glucose Excretion
Time Frame: Baseline, Week 12
Urine was collected over 24 hours to measure Urinary Glucose Excretion at baseline, and at the end of the 12-week treatment. Post-Baseline LS mean was obtained from ANCOVA model with treatment, randomization strata of insulin delivery method (CSII, MDI) as fixed categorical effects, and Baseline urinary glucose excretion as a covariate.
Baseline, Week 12
Change From Baseline to Week 12 in Fasting Plasma Glucose
Time Frame: Baseline to Week 12
Baseline was defined as the last value collected prior to the first dose of double-blind study medication. Post-Baseline LS mean was obtained from MMRM model with treatment, randomization strata of insulin delivery method (CSII, MDI), time (study week), and a treatment-by-time interaction as fixed categorical effects, and baseline fasting plasma glucose-by-time interaction as a covariate.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
