Trial summary

The primary purpose of this study is to evaluate the intrapulmonary PK, including epithelial lining fluid (ELF) and alveolar macrophages (AM) concentrations, of SPR719 compared to plasma concentrations of SPR719 (the active moiety in plasma of the prodrug SPR720) after oral administration of SPR720 1000 milligram (mg)… Read more about this study

About this study

Official title: A Phase 1, Single-center, Open-label Study to Assess the Intrapulmonary Pharmacokinetics of SPR719 by Comparing the Plasma, Epithelial Lining Fluid, and Alveolar Macrophage Concentrations Following the Oral Administration of Multiple Doses of SPR720 in Healthy Volunteers.

The primary purpose of this study is to evaluate the intrapulmonary PK, including epithelial lining fluid (ELF) and alveolar macrophages (AM) concentrations, of SPR719 compared to plasma concentrations of SPR719 (the active moiety in plasma of the prodrug SPR720) after oral administration of SPR720 1000 milligram (mg) capsules every 24 hours for 7 consecutive doses.

What is being measured

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

  1. Area Under the Concentration-time Curve from Time Zero to 24 Hours (AUC0-24) of SPR719 in plasma, ELF and AM

    Measured: Predose on Day 6 and post-dose at multiple time points up to Day 8

  2. Maximum Observed Concentration (Cmax) of SPR719 in plasma, ELF and AM

    Measured: Predose on Day 6 and post-dose at multiple time points up to Day 8

  3. Time to the Maximum Observed Concentration (Tmax) of SPR719 in plasma, ELF and AM

    Measured: Predose on Day 6 and post-dose at multiple time points up to Day 8

Secondary outcomes (1)
  1. Number of Participants With Treatment-emergent Adverse Events (TEAEs)

    Measured: From first dose of study drug until the follow-up visit (up to 15 days)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing SPR720 in people with Healthy Volunteer, run by Spero Therapeutics at 1 site in United States.

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 4 inclusion and 6 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 7 Mar 2024. 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 States. 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?

Area Under the Concentration-time Curve from Time Zero to 24 Hours (AUC0-24) of SPR719 in plasma, ELF and AM (time frame: Predose on Day 6 and post-dose at multiple time points up to Day 8). 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?

On the ClinicalTrials.gov record for NCT05955586, 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 7 Mar 2024.
