About this study

Official title: Comparative Randomized, Single Dose, Three-way, Three-sequence, Two Treatment, Partial Replicate, Crossover, Open-label Study to Determine the Bioequivalence of Nirmatrelvir & Ritonavir From Copaxid 150 +100 mg Tablets (Eva Pharma, Egypt) Versus Paxlovid 150 + 100 mg Film Coated Tablets (Pfizer Europe, Belgium)

Comparative randomized, single dose, three-way, three-sequence, two treatment, partial replicate, crossover, open-label study to determine the bioequivalence of Nirmatrelvir \& Ritonavir From Copaxid 150 +100 mg Tablets (Eva Pharma, Egypt) Versus Paxlovid 150 + 100 mg Film Coated Tablets (Pfizer Europe, Belgium)

Read the detailed description

Primary Pharmacokinetic Parameters: Cmax, AUC0→t and AUC0→∞ Secondary Pharmacokinetic Parameters: Ke, tmax and t1/2e. ANOVA using 5% significance level for transformed (with the 90% confidence intervals) and untransformed data of Cmax, AUC0→t and AUC0→∞ and for untransformed data of Ke, tmax and t1/2e.

The confidence intervals of logarithmically transformed Test/Reference ratios for Cmax, AUC0→t and AUC0→∞ to be within 80.00-125.00%.

A comprehensive final report will be issued upon the completion of the study.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Nirmatrelvir 150 mg + Ritonavir 100 mg (Reference first dose), Nirmatrelvir 150 mg + Ritonavir 100 mg (test) and Nirmatrelvir 150 mg + Ritonavir 100 mg (Reference second dose) in people with Healthy, run by Genuine Research Center, 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 12 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 18 Jan 2023. 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?

Cmax (time frame: Up to 48 hours post dose in each treatment period). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05491330, which also lists 3 linked publications.

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 18 Jan 2023.
