This is a 3 part phase 1, randomized, double-blind, placebo-controlled, study of the safety, tolerability, and pharmacokinetics of KVD824 following administration of single and multiple ascending oral doses; followed by a crossover food effect sub-study in healthy male volunteers.

Read the detailed description

Part A was a single-centre randomized, double blinded, placebo control to investigate the safety and tolerability of single ascending doses of KVD824 administered to healthy male volunteers.

Part B was a single centre, randomized, double blinded, placebo control to investigate the safety and tolerability of multiple ascending doses of KVD824 administered to healthy male volunteers.

Part C was a single-centre, open labelled to investigate the food effect.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing KVD824 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 16 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 17 Feb 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 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?

Safety - Treatment Emergent Adverse Events (time frame: Part A Days 0-10; Part B Days 0-12). The study lists 4 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 17 Feb 2022.
