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. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

21 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

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
Linagliptin: AUC_τ,ss
Time Frame: 24 hours
area under the concentration time curve (AUC_τ) of linagliptin in plasma at steady state over a uniform dosing interval
24 hours
Linagliptin: C_max,ss
Time Frame: 24 hours
maximum concentration of linagliptin in plasma at steady state
24 hours
DPP-4 Inhibition: E_24,ss
Time Frame: One single measurement 24 h after drug administration under steady state conditions
Plasma DPP-4 inhibition at trough under steady state conditions. Plasma DPP-4 inhibition is derived by calculating (1-(activity in presence of linagliptin)/baseline activity))*100%, where 'activity' is the activity of the DPP-IV enzyme.
One single measurement 24 h after drug administration under steady state conditions

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
Treatment Emergent Adverse Events
Time Frame: 21 days
Frequency of patients with AEs
21 days
Electrocardiogram (ECG), Vital Signs, Physical Finding or Laboratory Finding Abnormalities
Time Frame: 21 days
12-lead-Electrocardiogram (ECG), vital sign (blood pressure and pulse rate), physical finding and laboratory abnormalities
21 days
Patients With Electrocardiogram (ECG), Vital Signs, Physical Finding or Laboratory Finding Abnormalities Reported as an Adverse Event
Time Frame: 21 days
Patients with Electrocardiogram (ECG), vital signs, physical finding reported as an adverse event
21 days
Linagliptin: AUC_0-24
Time Frame: 24 hours
area under the concentration time curve of linagliptin in plasma over the time interval from 0 to 24h after administration of the first dose
24 hours
Linagliptin: C_max
Time Frame: 24h
maximum concentration of linagliptin in plasma on Day 1
24h
DPP-4 Inhibition: E_24
Time Frame: One single measurement 24 h after drug administration
Plasma DPP-4 inhibition 24 hours after first dose. Plasma DPP-4 inhibition is derived by calculating (1-(activity in presence of linagliptin)/baseline activity))*100%, where 'activity' is the activity of the DPP-IV enzyme.
One single measurement 24 h after drug administration

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.
