What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Relative Bioavailability Of Danicopan Prototype PIC 1 Formulation And Tablet Formulation

    The relative bioavailability of the PIC 1 formulation versus the tablet formulation will be measured by the ratio of select pharmacokinetic (PK) parameters: maximum observed plasma concentration (Cmax), area under the concentration-time curve from time of administration to the last measurable concentration (AUC0-t), and area under the concentration-time curve from time 0 extrapolated to infinity (AUC0-inf).

    Measured: Up to 72 hours postdose

    Measured: Up to 72 hours postdose

  6. Relative Bioavailability Of Danicopan Prototype PIC 2 Formulation And Tablet Formulation

    The relative bioavailability of the PIC 2 formulation versus the tablet formulation will be measured by the ratio of select PK parameters: Cmax, AUC0-t, and AUC0-inf.

    Measured: Up to 72 hours postdose

  7. AUC0-inf Of Danicopan Prototype PIC 2 Formulation Under Both Fed And Fasted Conditions

    Measured: Up to 72 hours postdose

  8. AUC0-t Of Danicopan Prototype PIC 2 Formulation Under Both Fed And Fasted Conditions

    Measured: Up to 72 hours postdose

  9. Cmax Of Danicopan Prototype PIC 2 Formulation Under Both Fed And Fasted Conditions

    Measured: Up to 72 hours postdose

  10. Tmax Of Danicopan Prototype PIC 2 Formulation Under Both Fed And Fasted Conditions

    Measured: Up to 72 hours postdose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Danicopan: Powder-In-Capsule 1, Danicopan: Powder-In-Capsule 2 and Danicopan: Tablet in people with Healthy, run by Alexion Pharmaceuticals, Inc. at 1 site in United States.

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 4 inclusion and 9 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 15 Apr 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 United States. 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?

Relative Bioavailability Of Danicopan Prototype PIC 1 Formulation And Tablet Formulation (time frame: Up to 72 hours postdose). The study lists 10 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 15 Apr 2022.
