Study groups in NCT03384186
Study groupRoleWhat they receive
Danicopan Modified Release Prototype TabletsExperimentalParticipants received danicopan once each period as a single oral dose as follows: Period 1: Danicopan Modified Release Prototype 1 under fasted conditions. Period 2: Danicopan Modified Release Prototype 2 under fasted conditions. Period 3: Danicopan Modified Release Prototype 3 under fasted conditions. Period 4: Danicopan Modified Release Prototype 2 under fed conditions. There was a washout period of at least 14 days between each danicopan dosing.
Receives: Drug: Danicopan Modified Release Prototype 1; Drug: Danicopan Modified Release Prototype 2; Drug: Danicopan Modified Release Prototype 3

What is being measured

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

  1. Time To Maximum Observed Concentration (Tmax) Of Danicopan After Treatment With Each Prototype Formulation

    Measured: Up to 72 hours postdose

  2. Maximum Observed Concentration (Cmax) Of Danicopan After Treatment With Each Prototype Formulation

    Measured: Up to 72 hours postdose

  3. Area Under The Concentration Versus Time Curve From Time 0 Extrapolated To Infinity (AUC0-inf) Of Danicopan After Treatment With Each Prototype Formulation

    Measured: Up to 72 hours postdose

Secondary outcomes (1)
  1. Participants Experiencing Treatment-emergent Adverse Events

    Measured: Day 1 (postdose) through follow-up visit (10 [+/- 2] days after last study drug administration)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Danicopan Modified Release Prototype 1, Danicopan Modified Release Prototype 2 and Danicopan Modified Release Prototype 3 in people with Healthy, run by Alexion Pharmaceuticals, Inc. at 1 site in United Kingdom.

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 3 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 20 Aug 2021. 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 Kingdom. 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?

Time To Maximum Observed Concentration (Tmax) Of Danicopan After Treatment With Each Prototype Formulation (time frame: Up to 72 hours postdose). 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 20 Aug 2021.
