About this study

Official title: A Phase 1, Randomized, Double-blind, Placebo-controlled, Dose-ranging Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Single and Multiple Doses of BCX7353 in Healthy Subjects

This is a 3-part Phase 1 dose-ranging study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single (Part 1) and multiple (Part 2) ascending doses of BCX7353 in healthy subjects, and single and multiple doses of BCX7353 in healthy Japanese subjects. Pharmacokinetics is an analysis of how the body handles the study drug BCX7353 and pharmacodynamics is an analysis of the activity the study drug BCX7353 may have in the body.

Read the detailed description

Up to 6 ascending, single dose cohorts are planned to be dosed in a sequential manner in Part 1 of the study. Eight subjects will be treated with a single dose of study drug per dose cohort (6 subjects per cohort will receive BCX7353 and 2 subjects per cohort will receive matching placebo). Escalation to the next higher dose level will occur only after completion of a review of clinical safety and pharmacokinetics by the Sponsor and PI.

Up to 4 ascending, multiple dose cohorts will be enrolled in a sequential manner in Part 2 of the study. Twelve subjects will be treated with study drug per dose cohort (10 subjects will receive BCX7353 and 2 subjects will receive placebo per cohort). The planned doses, dosing regimens, and duration of dosing (7 or 14 days) for each of the Part 2 cohorts will be determined based upon safety and pharmacokinetic data collected during the study. Escalation to the next higher dose level in Part 2 will occur only after completion of a review of clinical safety and pharmacokinetics by the Sponsor and clinical site study physician.

In Part 3 of the study, the safety, tolerability, PK, and PD of single and multiple doses of oral BCX7353 versus placebo in healthy subjects of Japanese origin will be evaluated. In the single dose cohort, 16 Japanese subjects will be randomized into a single cohort to receive either placebo or 1 of 2 active doses of BCX7353. In the multiple dose cohort, twelve subjects will be treated with study drug (10 subjects will receive BCX7353 and 2 subjects will receive placebo per cohort). The planned doses (single and multiple dose cohort), and dosing regimen and duration of dosing (7 or 14 days; multple dose cohort) for Part 3 will be determined based upon safety and pharmacokinetic data collected during Parts 1 and 2 of the study.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BCX7353 in people with Hereditary Angioedema, run by BioCryst Pharmaceuticals 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 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 13 Jan 2016. 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. Some participants in this study may receive a placebo. 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?

Adverse events (time frame: Part 1 and Part 3 single dose cohort: absolute and change from baseline through Study Day 7; Part 2 and Part 3 multiple dose cohort: absolute and change from baseline through 14 or 21 days (depending on dosing duration)). The study lists 5 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 13 Jan 2016.
