About this study

Official title: A Phase 1A Single Ascending Dose and Multiple Ascending Dose Double-Blind, Placebo-Controlled, Randomized Trial of Oral Inhalation PK10571 in Healthy Adult Subjects

This is a phase 1A randomized double blind placebo controlled single ascending dose and multiple ascending dose trial of inhaled PK10571 (GB002) in healthy adult subjects.

Read the detailed description

This is a first-in-human, single-center, randomized, double-blind, placebo-controlled, two-part study in healthy adult males and females of non-childbearing potential. "Double-Blind" means neither the study subject nor the investigator knows if PK10571 or placebo is being given. "Placebo" means a capsule filled with a powder that does not contain the active drug, PK10571. Because the safety profile of PK10571 in humans is unknown and this is the first clinical study to assess PK10571 in humans, a single-ascending dose design will be used in Part A of the study going from a low dose to higher doses based on safety. Part B will be a multiple-ascending dose design to be run only after review of safety and measurement of drug levels in the blood from Part A.

In the single ascending dose study (Part A) up to five doses may be given to different groups of study subjects based on safety and measurement of drug levels in the blood. Subjects will be randomized into one dose cohort to receive either PK10571 or placebo. Within each cohort, 6 subjects will receive active drug and 2 subjects will receive placebo.

In the multiple ascending dose study (Part B), up to three doses of PK10571 will be tested. The daily dose will be administered daily for 7 days with close clinical monitoring. The dose for the first cohort of Part B will be determined by review of the safety and drug levels from Part A by the Safety Review Committee. The dose interval for the first cohort of Part B (i.e., once daily, twice daily, or up to three times daily) will be determined by review of the safety and drug levels in the blood from Part A by the Safety Review committee. Subsequent doses and dosing intervals will be determined by review of the safety and drug levels from the prior cohort.

A TEAE is defined as any AE that has an onset on or after the first dose of study drug and before the end of study/end of treatment (EoS/ET) visit, or any pre-existing condition that has worsened in severity on or after the first dose of study drug and before the EoS/ET visit.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GB002 and Generic Dry Powder Inhaler in people with Safety Issues, run by GB002, Inc., a wholly owned subsidiary of Gossamer Bio, Inc. 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 8 inclusion and 53 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 9 Jun 2020. 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?

Yes. Results are posted in the registry (first posted 17 Feb 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With Treatment-Emergent Adverse Events (TEAEs) (time frame: SAD: from first dose of study drug to 11 days, MAD: from first dose of study drug to 35 days). The study lists 22 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 9 Jun 2020.
