About this study
Official title: Bioavailability of a Formulation of Oseltamivir Phosphate 75 mg Tablets With Regards to the Reference Product
This study will investigate the bioavailability in fasting male and/or non-pregnant and non- breast feeding female subjects of 1 tablet formulation containing Levodopa 250 mg and Carbidopa 25 mg. The study will be performed at a single site with 44 subjects. Participants will take 1 tablet of the test product and reference product in 2 periods and 2 sequences (either test after reference or reference after test). There will be a washout of at least 2 days between each study period.
Read the detailed description
The primary objective of the study is to investigate the relative bioavailability of Oseltamivir Phosphate 75 mg of 1 capsule formulations with Oseltamivir Phosphate 75 mg and to demonstrate bioequivalence of both formulations in terms of rate and extent of absorption:
- Test Product: Product manufactured by Laboratorios Silesia S.A.
- Reference Product: Sinemet [Trademark], product of Savio Industrial S.R.L., Brazil. The 90% confidence intervals for the intra-subject coefficient of variation (Test versus Reference Product) for the main pharmacokinetic parameters area under the plasma concentration-time curve from time zero to time t (AUC0 0-t) and from time zero to infinite (AUC0 0-∞), and maximum plasma concentration (Cmax) for total Levodopa and Carbidopa will be determined. Participants will be confined in the study site for approximately 68 hours during the entire study (for 10 hours pre-dosing and for 10 hours post dosing in period II) during which pharmacokinetic (PK) blood samples will be obtained. 23 blood samples will be taken up to 10 hours after the administration in each period. The washout period between the two study periods will be at least 2 days. The samples from each participant will be analyzed with validated LC-MS/MS method for estimation of Levodopa and Carbidopa in plasma. The safety objective is to evaluate the tolerability of both formulations in subjects by collecting adverse events.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Levodopa 250mg and Carbidopa 25mg Test Drug tablet and Levodopa 250mg and Carbidopa 25mg Referent Product tablet in people with Bioequivalence, run by Laboratorios Andromaco S.A. at 1 site in India.
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 11 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 8 Mar 2022. 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 India. 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?
Total Levodopa and Carbidopa: area under the plasma concentration-time curve from 0 to time t (AUC0-t) (time frame: 23 samples up to 10 hours will be taken after the administration in each period). 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 8 Mar 2022.
