About this study
Objective: To observe the effect of alogliptin combined with metformin on pulmonary function in obese patients with type 2 diabetes inadequately controlled by metformin monotherapy (500 mg, bid po, for at least 3 months), and evaluate its efficacy and safety.
Method: After a 2-week screening period, adult patients (aged 36-72 years) entered a 4-week run-in/stabilization period. Then, patients were randomly assigned to either the intervention group (n=55) or control group (n=50) for 26 weeks. The patients in the control group were given metformin (1,000 mg, bid po) and the patients in the intervention group were given metformin (500 mg, bid po) combined with alogliptin (25 mg, qd po). All the patients received counseling about diet and exercise from a nutritionist during run-in and treatment periods.
The primary endpoints were the between-group differences in the changes pulmonary function parameters [VC%, FVC%, FEV1%, PEF%, MVV%, TLC%, FEV1/FVC%, DLCO%, and DLCO/VA%] between pretherapy and posttreatment. The secondary endpoints were changes from baseline to week 26 in HbA1c, FPG, 2hPG, HOMA-IR, WC, and BMI. The tertiary endpoints were the changes from baseline to week 26 in blood-fat (TC, HDL-C, LDL-C, and TG). The quartus endpoints were the changes from baseline to week 26 in SBP and DBP. The fifth endpoints were the changes from baseline to week 26 in oxidative/antioxidative parameters (ROS, MDA, SOD, and GSH-PX). In addition, safety endpoints were assessed (AEs, clinical laboratory tests, vital signs, and electrocardiographic readings).

Alogliptin and MetforminDrug
The patients in the control group were given metformin (1,000 mg, bid po) and the patients in the intervention group were given metformin (500 mg, bid po) combined with alogliptin (25 mg, qd po)
| Study group | Role | What they receive |
|---|---|---|
| Alogliptin+metformin | Experimental | Alogliptin (alogliptin benzoate) is the most recent DPP-4 inhibitor; it entered the market in 2006. It is a potent and highly selective DPP-4 inhibitor with oral antidiabetic activity; Metformin is the most commonly prescribed first-line drug worldwide for the treatment of T2DM, it acts by decreasing both hepatic glucose production and intestinal glucose absorption, while improving insulin sensitivity, metformin as a safe and valid oral antidiabetic drug was recommended to the obese patients with a body mass index (BMI) >30 kg/m2, it has some value in reducing or preventing weight gain and changes in metabolic parameters during treatment, and it can be combinated with other antidiabetic drug Receives: Drug: Alogliptin and Metformin |

Questions about this trial
What is this clinical trial studying?
A study testing Alogliptin and Metformin in people with Diabetes Mellitus, Type 2, run by Fourth People's Hospital of Shenyang.

Who may be eligible to take part?
The sponsor lists 3 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Jun 2016. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The primary endpoints were changes from baseline to week 26 in pulmonary function parameters [VC%, FVC%, FEV1%, PEF%, MVV%, TLC%, FEV1/FVC%, DLCO%, and DLCO/VA%] between pretherapy and posttreatment. (time frame: 26 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jun 2016.
