About this study

Official title: A Phase 1, Open-Label, Four-Period, Two-Sequence, Two-Treatment, Single Dose, Randomized, Crossover Bioequivalence Study of a Test Tablet Formulation of Ravidasvir With the Reference Tablet Formulation of Ravidasvir in Healthy Adult Volunteers Under Fasting Conditions

In a phase 1, open-label, crossover study to evaluate the relative bioavailability of a tablet formulation of ravidasvir (test) versus the capsule formulation of ravidasvir (reference) in 24 healthy adult volunteers (PPI-668-104 study), relatively high intra-subject coefficients of variation were observed for both Cmax and AUC0-t.

A two-sequence, four-period replicate design will be used to allow the possibility to scale the acceptance range for Cmax if the observed intra-subject coefficient of variation for the reference formulation is greater than 30%

Read the detailed description

During the course of development, a new batch of ravidasvir tablets has been prepared by the proposed commercial manufacturer (Doppel Farmaceutici, Italy). Tablets manufactured by Doppel Farmaceutici are intended to be used in subsequent clinical trials and be registered as the commercial product. The purpose of this Phase 1, Open-Label, Four-Period, Two-Sequence, Two-Treatment, Single Dose, Randomized, Crossover Bioequivalence Study is to assess if ravidasvir 200 mg tablets supplied by European Egyptian Pharmaceutical Industries (EEPI) and tablets from Doppel Farmaceutici are bioequivalent.

Primary objectives:

To compare the rate and extent of absorption for ravidasvir (RDV) when administered as a single 200 mg oral dose of the proposed commercial product ("test") produced by Doppel Farmaceutici with the clinical trial product ("reference") manufactured by EEPI in healthy volunteers, under fasted conditions.

Secondary objectives To evaluate the safety and tolerability of single oral doses of RDV in healthy volunteers.

Being tested
Ravidasvir test formulation produced by Doppel, Ravidasvir reference formulation produced by EEPI

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Ravidasvir test formulation produced by Doppel and Ravidasvir reference formulation produced by EEPI in people with Bioequivalence Study, run by Drugs for Neglected Diseases at 1 site in Malaysia.

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 14 inclusion and 15 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 31 Jan 2020. 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 Malaysia. 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?

RDV Plasma CMax when administered as a single 200 mg oral dose of the test versus reference product (time frame: Measurement within 48 hours post-dose). The study lists 3 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 31 Jan 2020.
