About this study

Official title: A Local Phase IV, Multicenter, Open-label Study to Evaluate Early add-on Vildagliptin in Patients With Type 2 Diabetes Inadequately Controlled by Metformin

The purpose of this study was to observe change of HbA1c over time from baseline to month 12. The ultimate goal of this study was to provide a local reference value to the physicians \& patients in the future when they consider initiating Vildagliptin and taking balance between efficacy, compliance, risk factors, convenience and medication cost.

Being tested
LAF237 (vildagliptin), Metformin
Keywords
type-2 diabetes mellitus, inadequately controlled Metformin

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change of Glycosylated Hemoglobin A1c (HbA1c) From Baseline to Month 12

    HbA1c is an integrated measure of average glucose concentration in plasma in the last 2-3 months. Blood samples were collected to analyze HbA1c

    Measured: Baseline, Month 12 (weeK 52)

Secondary outcomes (5)
  1. Change of Glycosylated Hemoglobin A1c (HbA1c) From Baseline to Month 3, 6, 9 and 12 (Based on MMRM Analysis)

    HbA1c is an integrated measure of average glucose concentration in plasma in the last 2-3 months. Blood samples were collected to analyze HbA1c. Mixed Model of Repeated Measures (MMRM) was used to analyze this outcome. For the MMRM analysis, the model includes terms for treatment, period, treatment-by-period interaction and baseline value, and further adjusted by age, pre-existing hypertension and microvascular and macrovascular complications for diabetes mellitus. The variables selected for baseline adjustment were based on the lowest AIC.

    Measured: Baseline, Month 3, 6, 9 and 12

  2. Change in Fasting Plasma Glucose (FPG) From Baseline to Month 3, 6, 9 and 12 (Based on MMRM Analysis)

    Blood samples were collected to analyze fasting plasma glucose. Mixed Model of Repeated Measures (MMRM) was used to analyze this outcome. For the MMRM analysis, the model included terms for treatment, period, treatment-by-period interaction and baseline value, and further adjusted by pre-existing hypertension. The variable selected for baseline adjustment was based on the lowest AIC.

    Measured: Baseline, Month 3, 6, 9 and 12

  3. Percentage of Patients Achieving Good Glycemic Control

    Blood samples were collected to analyze HbA1c. Good glycemic control is defined as patient achieving Hb1Ac < 7.0%. Percentage of patients who achieved HbA1c less than 7.0% at month 3, 6, 9 and 12 were reported for this endpoint.

    Measured: Month 3, 6, 9, 12

  4. Percentage of Overall Drug Compliance in 12 Months

    The overall drug compliance (%) = (Observed Consumption / Expected Consumption) x 100% Where (Observed Consumption / Expected Consumption) = [1- (Number of missing tablets from all visits/(sum of Allocated Daily Dosage (in tablets) from all visits × No. of Days between the Date Dispensed and the Date Returned))]

    Measured: Month 12

  5. Number of Patients With Adverse Events, Serious Adverse Events and Death as an Assessment of Overall Safety and Tolerability

    This analysis reported percentage patients with adverse events and patient discontinued from the study due to adverse events. Aslo, percentage of patients with serious adverse events and death was reported.

    Measured: Month 12

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing LAF237 (vildagliptin) and Metformin in people with Type-2 Diabetes Mellitus, run by Novartis Pharmaceuticals at 4 sites in Hong Kong.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 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 15 May 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Hong Kong. Whether a site is taking part right now should be confirmed with that site. See every site.

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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Apr 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Change of Glycosylated Hemoglobin A1c (HbA1c) From Baseline to Month 12 (time frame: Baseline, Month 12 (weeK 52)). 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 15 May 2017.
