About this study

Official title: A Randomized, Double-blind, Placebo-controlled, Phase 1 Study of the Safety, Tolerability and Pharmacokinetics of Single and Multiple Ascending Doses of BWC0977 in Healthy Adult Volunteers

The purpose of this study is to assess the safety, tolerability and pharmacokinetics of single and multiple intravenous doses of BWC0977 when administered to healthy adult volunteers.

Read the detailed description

This Phase 1 study is designed to assess the safety, tolerabilty and pharmcokinetics of single and multiple intravenous doses of BWC0977 when administered to healthy adult volunteers. This is a randomized double-blind, placebo-controlled, ascending dose, multi-cohort trial. A total of 64 healthy volunteers are expected to be enrolled into 8 Cohorts. The study will be conducted in two phases: A single ascending dose (SAD) phase, followed by a multiple ascending dose (MAD) phase. In SAD, participants in Cohorts 1 - 5 will receive one dose of BWC0977 or placebo. In MAD, participants in Cohorts 6 - 8 will receive multiple doses of BWC0977 or placebo for 10 consecutive days at a dose deemed safe and tolerable as determined in the preceding SAD Cohorts. In both parts sequential cohorts will be exposed to increasing doses of BWC0977.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • BWC0977Drug

    SAD Cohorts: Double-blind dosing will occur. Six participants will receive single doses of BWC0977. The dose escalation steps may be altered following review of the safety data upon completion of each cohort.

    MAD Cohorts: Double blind dosing will occur. Six participants in each cohort will receive multiple doses of BWC0977. The dose escalation steps may be altered following review of the safety data upon completion of each cohort. Dosing will commence on the morning of Day 1. Dosing frequency to be confirmed based on safety, tolerability and PK data from SAD cohorts. Daily dosing will continue for a total of 10 consecutive days.

  • PlaceboDrug

    Also called Compounded solution minus BWC0977

    SAD Cohorts: Two participants in each cohort will receive matching placebo. MAD Cohorts: Two participants in each cohort will receive matching placebo.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BWC0977 in people with Infectious Diseases and Bacterial Infections, run by Bugworks Research Inc. at 1 site in Australia.

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 8 inclusion and 20 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 6 Jul 2023. 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 Australia. 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?

Incidence of treatment-emergent adverse events (TEAEs and serious adverse events (SAEs) overall and by intensity (Safety and tolerability). (time frame: SAD: Up to 7 days; MAD: Up to 15 days.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05088421, which also lists 1 linked publication.

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 6 Jul 2023.
