Diabetes Mellitus, Type 2NCT01195259
Malignancy Meta Analysis for BRL49653
An observational study of Diabetes Mellitus, Type 2, run by GlaxoSmithKline.
Trial summary
Observational analyses of data from population registeries have suggested that metformin may be associated with a decreased prevalence of malignancy. The ADOPT and RECORD studies both contain groups of subjects randomly allocated to metformin and rosiglitazone. Read more about this study

Study population: 5135 subjects with type 2 diabetes mellitus from the intention to treat (ITT) populations of 2 randomised, controlled studies (2576 metformin/2559 rosiglitazone)
Subjects from ADOPT that are included in this meta-analysis (those in the metformin or rosiglitazone groups) had the dose of their study medication increased to a maximum of 2g (metformin) or 8mg (rosiglitazone) if their fasting plasma glucose was greater than 140mg/dl.
Subjects from RECORD that are included in this meta-analsyis entered the RECORD study taking one of three sulfonylureas (glibenclamide, gliclazide or glimepiride). They were randomly allocated to metformin or rosiglitazone in a 1:1 ration to use as add-on treatment to the background of sulfonylurea. These subjects had the dose of their study medication increased to a maximum of 2.55g (metformin) or 8mg (rosiglitazone) if their HbA1c was greater than 7.0%.
About this study
Official title: A Meta Analysis of Malignancy Serious Adverse Events in the ADOPT, 49653/048, and RECORD, 49653/231, Studies, Comparing Metformin With Rosiglitazone.
Observational analyses of data from population registeries have suggested that metformin may be associated with a decreased prevalence of malignancy. The ADOPT and RECORD studies both contain groups of subjects randomly allocated to metformin and rosiglitazone. This meta-analysis combines malignancy serious adverse events from ADOPT and RECORD in order to compare their incidence on metformin with that on rosiglitazone.
Read the detailed description
The objective of this meta-analysis is to compare the incidence of malignancy (excluding non-melanomatous skin cancers) reported as serious adverse events in the ADOPT and RECORD studies between subjects randomly allocated to treatment with metformin with those allocated to rosiglitazone.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
allocation of treatment with metformin or rosiglitazoneDrug
Subjects from ADOPT that are included in this meta-analysis were randomly allocated to receive metformin or rosiglitazone. Subjects from RECORD that are included in this meta-analysis were taking one of three sulfonylureas (glibenclamide, gliclazide or glimepiride) and were randomly allocated metformin or rosiglitazone to use as add-on treament to background sulfonylurea.

Questions about this trial
What is this clinical trial studying?
An observational study of Diabetes Mellitus, Type 2, run by GlaxoSmithKline.
The full registered description is in the About this study section and the official record.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 Oct 2013. 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?
Time to first occurrence of a serious adverse event of malignancy (excluding non-melanomatous skin cancers) (time frame: ADOPT approximately 4 years duration, RECORD approximately 5.5 years duration). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01195259, which also lists 1 linked publication.
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 28 Oct 2013.
