About this study
Official title: A SingleDose Rand, TwoPeriod, Crossover Bioequivalence Study Between a Combination Tablet With Paracetamol, Guaifenesin and Penylephrine HCL (Wrafton Lab Ltd, UK) and Vicks Active SymptoMax Plus, Powder for Oral Solution (Wrafton Lab Ltd, UK) in Healthy Adult Volunteers
This is a single-dose, randomized, two-period cross-over study with 72 healthy male and female volunteers. The investigational products will be given (after fasting overnight) at separate visits separated by 7 ± 3 days. Blood for pharmacokinetic analyses will be drawn pre-dose and at 5, 10, 15, 20, 25, 30, 40, 60, 75, 90, 105 minutes, as well as 2, 2.25, 3, 4, 5, 6, 8, and 12 hours after drug administration. Subjects will also be monitored to capture any adverse events that may occur. Bioequivalence will be assessed based on the single-dose pharmacokinetics of paracetamol, guaifenesin and phenylephrine, respectively

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Tablet paracetamol, guaifenesin and phenylephrine HCL and Vicks Active SymptoMax Plus powder for oral solution in people with Bioequivalence and Healthy Volunteers, run by Johnson & Johnson Consumer and Personal Products Worldwide at 1 site in Russia.
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 5 inclusion and 21 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 6 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Russia. 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 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?
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?
Peak Plasma Concentration (Cmax) of paracetamol, guaifenesin and phenylephrine (total) (time frame: At baseline and during 12 hours after product administration). The study lists 8 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 6 Jul 2018.
