Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Monocentric, Prospective, Randomized, Open-label, Comparative, Phase IV Study, to compare the effects of Vildagliptin and Gliclazide MR on Markers of Bone Remodeling, Bone Mineral Density and Glycemic Variability in Postmenopausal Women with Type 2 Diabetes.

A total of 38 women with documented Type 2 Diabetes and menopause will be enrolled. The active treatment will include a 50 mg dose of vildagliptin OD twice a day. As comparator, gliclazide MR will be administered at a dose of 60 to 120 mg OD once a day.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Monocentric, Prospective, Randomized, Open-label, Comparative, Phase IV Study, to compare the effects of Vildagliptin and Gliclazide MR on Markers of Bone Remodeling, Bone Mineral Density and Glycemic Variability in Postmenopausal Women with Type 2 Diabetes.

Target population of clinical trial subjects A total of 38 women with documented Type 2 Diabetes and menopause will be enrolled. To be as close to a real life scenario as possible, clinical trial subjects which are treated with glucose-lowering medication (except incretin or sulfonylurea based therapies) and treatment-naive subjects will be included.

Investigational Product, posology and method of administration The active treatment will include a 50 mg dose of vildagliptin OD twice a day.

Comparator, posology and method of administration As comparator, gliclazide MR will be administered at a dose of 60 to 120 mg OD once a day.

Treatment duration The study will have an expected total duration of 18 months, 12 months of active treatment.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Informed consent form obtained before any study-related activity. Study-related activities are any procedure that would not be performed during the normal treatment of the patient.

* Menopause defined as:
* Absence of menstruation for at least 12 months in patients with an intact uterus, or
* FSH level greater than 30 mIU/mL in a hysterectomized patient and/or,
* FSH level greater than 30 mIU/mL in a patient with surgical menopause.

Exclusion Criteria

* Sustained arterial hypertension \> 180/100 mm Hg.
* Body mass index (BMI) \> 50 kg/m².
* HbA1c ≥ 9,5% at randomization.
* Transaminases (AST (SGOT) and ALT (SGPT)) \> 2.5 x upper limit of normal.
* Chronic liver disease or alcoholic liver disease.

* HDL-cholesterol \< 25 mg/dL (\< 0.64 mmol/L).
* Levels of 25-OH-vitamin D \< 20ng/mL at randomization
* Abnormal levels of PTH, cortisol, IGF-1 or GH at randomization
* Prescription of any investigational medication within one year before the screening visit (visit 1), unless there is a direct benefit to the study subject, at the discretion of the investigator.
* History of previous fracture
* Pregnant or breastfeeding patients.
* Previous participation on this study.
* Individuals at risk for poor adherence to the protocol or medication.
* Any condition that makes the patient unable to complete the study within 12 months.
