About this study
Official title: A Single Dose, Randomized, Open-label, Replicated Crossover Bioequivalence Study of Generic Simvastatin 40 mg Film-coated Tablets and Reference Product (ZOCOR®) in Healthy Thai Volunteers Under Fasting Conditions
The goal of this bioequivalence study is to determine and compare the rate and extent of absorption and to evaluate safety of test and reference formulations. Study Design: An open label, randomized, two-treatment, four-period, two-sequence replicate crossover bioequivalence study in 46 healthy Thai volunteers under fasting conditions with at least 7 days washout period.
Read the detailed description
The primary objective of this bioequivalence study is to assess and compare the rate and extent of absorption of a test formulation against a reference formulation, with an additional focus on evaluating the safety profiles of both formulations. This study aims to provide critical insights into the bioequivalence of the two formulations, shedding light on their pharmacokinetic parameters and overall safety in the context of therapeutic efficacy.
Study Design:
The study adopts an open-label, randomized, two-treatment, four-period, two-sequence replicate crossover design to ensure robustness and reliability in the evaluation of bioequivalence. The crossover design minimizes the impact of inter-individual variability, allowing for a more accurate assessment of the formulations' performance.
Participant Selection:
A total of 46 healthy Thai volunteers will be recruited to participate in the study. The inclusion criteria involve individuals who meet specific health standards and are willing to comply with the study requirements. The emphasis on recruiting healthy volunteers aims to establish a baseline for comparison, ensuring that any observed differences in absorption and safety can be attributed to the formulations under investigation.
Study Conditions:
The study will be conducted under fasting conditions to isolate the impact of the formulations on absorption without interference from food-related variables. Fasting conditions provide a controlled environment to evaluate the formulations' performance and allow for a more accurate determination of bioequivalence.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Simvastatin 40 mg film-coated tablet and Zocor 40 mg film-coated tablet in people with Healthy Volunteer, run by International Bio service.
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 7 inclusion and 32 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: status not confirmed, as of the sponsor's last update on 7 Mar 2024. 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.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Nannapat Wannaphruek, Pharm.D. (024415211, nannapat.wan@mahidol.ac.th), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Plasma Area Under the Curve (AUC(0 to 48hr)) for Simvastatin Acid (time frame: Through 48 Hours Post Dose). The study lists 4 primary outcomes in all. 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 7 Mar 2024; AzTrials last refreshed its copy on 8 Nov 2026.
