What is being measured

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

  1. Concentration of GBT021601 in whole blood and plasma

    To evaluate the single-dose whole blood and plasma PK of GBT021601 in participants with renal impairment (RI)

    Measured: Up to 112 Days

  2. Single-dose PK parameters

    To evaluate the single-dose whole blood and plasma PK of GBT021601 in participants with renal impairment

    Measured: Up to 112 Days

Secondary outcomes (2)
  1. Incidence of treatment-emergent adverse events (TEAEs), clinically significant changes in laboratory assessments, electrocardiograms (ECGs), and vital signs

    To evaluate the safety and tolerability of single dose GBT021601 in participants with renal impairment

    Measured: Up to 112 Days

  2. Incidence of treatment-emergent adverse events (TEAEs), clinically significant changes in laboratory assessments, electrocardiograms (ECGs), and vital signs

    To evaluate the safety and tolerability of GBT021601 in ESRD participants receiving IHD following a single dose

    Measured: Up to 112 Days

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GBT021601 in people with Renal Impairment, run by Pfizer at 4 sites 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 3 inclusion and 2 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: stopped early, as of the sponsor's last update on 15 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites 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 was stopped early (reason given: Business decision to terminate the trial after the completion of Part 1: Cohort 1 (severe renal impairment). The decision to terminate the trial was not due to any potential safety concerns.). Results are not available in the source record.

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?

Concentration of GBT021601 in whole blood and plasma (time frame: Up to 112 Days). The study lists 2 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 15 Oct 2024.
