About this study

Official title: A Multiple Part, Phase 1 Crossover Study in Healthy Subjects to Evaluate the Pharmacokinetic (PK) Profile of KVD824 Following Single and Multiple Doses of Novel KVD824 Modified Release (MR) Formulations Compared to a Reference KVD824 Immediate Release (IR) Formulation

This is a 3 part, phase 1 crossover study in healthy subjects to evaluate the pharmacokinetic profile of KVD824 following single and multiple doses of novel KVD824 modified-release formulations compared with a reference KVD824 immediate release formulation.

Read the detailed description

Part 1 of the study was a single-centre, open-label, non-randomised, 6-period crossover study designed to investigate the PK and safety of KVD824 MR prototype formulations (with or without an additional KVD824 IR capsule) compared to a reference KVD824 IR capsule formulation in healthy male and female subjects. Part 2 was an optional part designed to investigate the PK and safety of a selected KVD824 MR prototype tablet formulation (with or without an additional KVD824 IR capsule) in healthy male and female subjects in both the fed and fasted state. Note: this Part was not conducted as sufficient information on food effect was collected in the other Parts of the study.

Part 3 was a single-centre, randomised, double-blind, placebo-controlled, multiple dose group study to investigate the PK and safety of a selected KVD824 MR prototype tablet formulation (with or without an additional KVD824 IR capsule) in healthy male and female subjects. Part 3 started following completion of Part 1.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing KVD824 Prototype 1 modified-release tablet, KVD824 Prototype 2 modified-release tablet and KVD824 Immediate-Release Capsule in people with Hereditary Angioedema, run by KalVista Pharmaceuticals, Ltd. 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 22 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 12 Nov 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. 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?

Pharmacokinetics - Tlag (time frame: Days 1, 10 and 14). The study lists 30 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 12 Nov 2021.
