Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

All patients admitted to Diabetes clinics of Minia University Hospital, will be screened for the eligibility criteria.

diabetic patients (aged above 50 years) with uncontrolled diabetes on oral hypoglycemic drugs. 105 patients will be enrolled and randomized into three groups.

Group I=35 T2DM patients given DPP4Is Group II=35 T2DM patients given DPP4Is and metformin. Group III=35 patients will be given placebo (only adjust their drugs to control blood glucose level)

Study Type

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
105

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

  • Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

Type-2 diabetic adult subjects (above 50 years old) who had uncontrolled (A1c=8-9 %) blood glucose levels with an oral hypoglycemic drug at the screening visit were eligible to participate.

Exclusion Criteria:

Those with type1 diabetes or ketoacidosis, end organ failure as chronic renal failure (estimated serum creatinine level ≥ 1.5mg/dl in male and ≥ 1.4mg/dl in female), liver cell failure (elevated alanine transaminase (ALT) and aspartate transaminase (AST) ≥ 2 folds), and heart failure, previous history of pancreatitis, and pregnant or lactating females were excluded from the study.

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
Serum Inflammatory mediators; TNF-α
Time Frame: Before and post 6 month of treatment
ELISA kits
Before and post 6 month of treatment
MMSE score
Time Frame: Before and post 6 month of treatment
Validated questionnaire assessing the Estimation of Mini Mental State The MMSE has a maximum score of 30 points. The scores are generally grouped as follows: 25-30 points: normal cognition 21-24 points: mild dementia 10-20 points: moderate dementia Examination (MMSE) score
Before and post 6 month of treatment
PHQ-9
Time Frame: Before and post 6 month of treatment
Validated questionnaire assessing patient mental health and depression PHQ-9 scores of 5, 10, 15, and 20 represents mild, moderate, moderately severe and severe depression.;
Before and post 6 month of treatment
serum amyloid-β
Time Frame: Before and post 6 month of treatment
Before and post 6 month of treatment

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
Serum Insulin
Time Frame: Before and post 6 month of treatment
ElISA kits
Before and post 6 month of treatment
Serum fasting and 2-he post prandial glucose
Time Frame: Before and post 6 month of treatment
Before and post 6 month of treatment
HOMA-IR

Primary Completion (Estimated)

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.
