About this study

Official title: A Phase 1, Randomized, Four-Period, Crossover Food-Effect Study With Mitapivat Sulfate In Healthy Subjects

This is a Phase 1, randomized, single-dose, double-blinded, 4-period, crossover study to evaluate the pharmacokinetics, safety, and tolerability of mitapivat in healthy adult participants under fasted and fed (high-fat meal) conditions. Secondary objectives include evaluating the effect of mitapivat on electrocardiogram (ECG) parameters, including concentration-QT interval corrected for heart rate (C-QTc) analysis under fasted conditions. The study will include a 28-day screening period, four 7-day treatment periods. Participants will receive a follow-up telephone call within 28 (±1) days after the last dose of study drug.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Mitapivat 100 mg and Mitapivat 300 mg in people with Healthy Volunteers, run by Agios Pharmaceuticals, 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 14 inclusion and 33 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 18 Feb 2021. 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. 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?

Area Under the Plasma Concentration Versus Time Curve (AUC) From Time 0 to the Last Quantifiable Concentration (AUC0-T) for Mitapivat Under Fasted and High-Fat Meal Conditions (time frame: Predose and at various timepoints through 120 hours postdose within each 7-day period). The study lists 9 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 18 Feb 2021.
