About this study
Official title: A Randomized, Single Oral Dose, Two-way Crossover, Open-label, Laboratory Blind, Bioequivalence Study Comparing Ribavirin From Two Different Drug Products After Oral Administration to Healthy Adult Subjects Under Fed Conditions
To evaluate and compare the relative plasma bioavailability and therefore the bioequivalence of two different immediate release products each containing Ribavirin 400 mg, after administering a single oral dose, to healthy adult subjects under fed conditions.
Read the detailed description
Enrolled subjects were randomized in a two-phase, two-sequence, cross-over design to receive a single dose of the test product (T) or the reference product (R) each phase, under fed conditions, with a wash-out period of 42 days.
Ribavirin plasma concentration was determined using a validated LC-MS-MS method, followed by Pharmacokinetics, and statistical analysis using Phoenix WinNonlin® software to determine the average bioequivalence.

Copegus® 200 mg film coated tablet (2*200mg)Drug
Also called Reference product (R)
an immediate release film-coated tablet containing 200 mg Ribavirin
| Study group | Role | What they receive |
|---|---|---|
| Test product (T) | Experimental | Subjects were served a standardized high caloric meal 30 minutes before the administration of a single film-coated tablet containing 400 mg Ribavirin (1*400mg) with approximately 240 ml of water Receives: Drug: Ribavirin 400 mg film coated tablet (1*400mg) |
| Reference product (R) | Active comparator | Subjects were served a standardized high caloric meal 30 minutes before the administration of two film-coated tablets each containing 200 mg Ribavirin (2*200mg) with approximately 240 ml of water Receives: Drug: Copegus® 200 mg film coated tablet (2*200mg) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Maximum plasma concentration (Cmax)
Cmax is observed as the maximum of Ribavirin peak concentration
Measured: Pre-dose (0) and at 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.5, 4, 6, 8, 10, 12, 24, 48, 72 hours post dose
Truncated area under the plasma concentration curve from administration to last observed (AUC 0-72h)
The AUC (0-72h) is the area under the plasma concentration with time curve from the time of dosing to the 72-hour sample
Measured: Pre-dose (0) and at 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.5, 4, 6, 8, 10, 12, 24, 48, 72 hours post dose
Secondary outcomes (1)
Maximum time (Tmax)
Time until Cmax is reached
Measured: Pre-dose (0) and at 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.5, 4, 6, 8, 10, 12, 24, 48, 72 hours post dose

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Ribavirin 400 mg film coated tablet (1*400mg) and Copegus® 200 mg film coated tablet (2*200mg) in people with Healthy Subjects, run by Future University in Egypt at 1 site in Egypt.
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 6 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 Sep 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 Egypt. 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?
Maximum plasma concentration (Cmax) (time frame: Pre-dose (0) and at 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.5, 4, 6, 8, 10, 12, 24, 48, 72 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 8 Sep 2022; AzTrials last refreshed its copy on 8 Nov 2026.
