- Have sitting systolic blood pressure of less than 90 mmHg or more than 139 mmHg and diastolic blood pressure of less than 60 mmHg or more than 89 mmHg on screening day and on the check-in day. If abnormal blood pressure detects, the measurement should be repeated two more times after take a rest for at least 5 minutes each. The last measurement value should be used to determine the subject's eligibility.
- Investigation of vital signs shows pulse rate less than 60 or more than 100 beats per minute on screening day and on the check-in day. If abnormal pulse rate detects, the measurement should be repeated two more times after take a rest for at least 5 minutes each. The last measurement value should be used to determine the subject's eligibility

If QTc exceeds 450 msec, or QRS exceeds 120 msec, the ECG will be repeated two more times and the average of the three QTc or QRS values will be used to determine the subject's eligibility

About this study
Official title: A Single Dose, Randomized, Open-label, Two-way Crossover Bioequivalence Study of Generic Acyclovir 800 mg Tablet and Reference Product (ZoviraxTM) in Healthy Thai Volunteers Under Fasting Conditions
A Single Dose, Randomized, Open-label, Two-way Crossover Bioequivalence Study of Generic Acyclovir 800 mg Tablet and Reference Product (Zovirax™) in Healthy Thai Volunteers under Fasting Conditions
Read the detailed description
This study is conducted to investigate bioequivalence information which is required to ensure therapeutic equivalence of a test product and a reference product as well as to be considered as one aspect of product quality. Bioequivalence is defined as the absence of a significant difference in the rate and extent to which the active ingredient or active moiety in pharmaceutical equivalents or pharmaceutical alternatives becomes available at the site of drug action when administered at the same molar dose under similar conditions in an appropriately designed study.
The manufacturer in Thailand needs to formulate a generic acyclovir 800 mg tablet. This study has been planned to evaluate the pharmacokinetics of this formulation and determine its bioequivalence with the reference product, Zovirax™, at the same dose.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Acyclovir 800 mg Tablet and Zovirax™ 800 mg 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 0 inclusion and 29 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 29 Jan 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 (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 36 Hour)) for Acyclovir (time frame: Through 36 Hours Post Dose). The study lists 2 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 29 Jan 2024.
