Chronic PeriodontitisPhase 2/3NCT03204058
Locally Delivered Metformin & Rosuvastatin for Treatment of Intrabony Defects in Chronic Periodontitis
A Phase 2/3 study testing Rosuvastatin and Metformin in people with Chronic Periodontitis, run by Government Dental College and Research Institute, Bangalore.
Trial summary
Metformin (MF), a biguanide group of anti-diabetic drug has been shown to enhance osteoblasts differentiation and inhibit osteoclast differentiation in vitro, thus may exhibit a favourable effect on alveolar bone. Read more about this study

About this study
Official title: Comparative Evaluation of Locally Delivered 1% Metformin and 1.2% Rosuvastatin Gel in Treatment of Intrabony Defects in Chronic Periodontitis Subjects: A Randomized Controlled Clinical Trial
Metformin (MF), a biguanide group of anti-diabetic drug has been shown to enhance osteoblasts differentiation and inhibit osteoclast differentiation in vitro, thus may exhibit a favourable effect on alveolar bone. Statins are one of the lipid lowering drugs that help in reducing cholesterol levels in the body by specifically inhibiting 3-hydroxy-3-methylglutaryl coenzyme A reductase; which is a rate limiting enzyme for cholesterol synthesis. Rosuvastatin (RSV) have shown to have bone stimulatory and anti-inflammatory effects.Statins are one of the lipid lowering drugs that help in reducing cholesterol levels in the body by specifically inhibiting 3-hydroxy-3-methylglutaryl coenzyme A reductase; which is a rate limiting enzyme for cholesterol synthesis. Rosuvastatin (RSV) and atorvastatin (ATV) have shown to have bone stimulatory and anti-inflammatory effects.. The present study aims to explore the efficacy of 1.2% RSV and 1MF gel as a local drug delivery and redelivery system as an adjunct to scaling and root planing (SRP) for the treatment of intrabony defects.

Methods: Ninety patients with intrabony defects were randomly allocated into three treatment groups: SRP plus placebo gel (group 1), SRP plus 1.2% RSV gel (group 2) and 1% MF gel (group3). Clinical and radiographic parameters were recorded at baseline then after 6 months. The gels were delivered at the respective sites at baseline . Then again all clinical and radiographic parameters were recorded after 6 months and 12 months.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Rosuvastatin and Metformin in people with Chronic Periodontitis, run by Government Dental College and Research Institute, Bangalore.
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 1 inclusion and 3 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 29 Jun 2017. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Change in Bone defect fill (time frame: baseline, 6 & 12 months). 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 29 Jun 2017.
