About this study

Official title: An Open-Label, 3-Part, 2-Period Study to Examine the Effect of Omeprazole (Part 1), Famotidine (Part 2), and of an Acidic Beverage (Part 3) on the Single-Dose Pharmacokinetics of Entinostat in Healthy Adult Subjects

The purpose of this study is therefore to evaluate the effect of concomitant drugs through an increase of intra-gastric pH levels on the bioavailability of entinostat.

The primary objectives of this study are to evaluate the effect of multiple doses of omeprazole, famotidine, and the effect of an acidic beverage in combination with omeprazole on the single-dose PK profile of entinostat.

The secondary objectives are to evaluate the safety and tolerability of a single dose of entinostat when administered with multiple doses of omeprazole, famotidine, and when administered with an acidic beverage in combination with omeprazole.

Read the detailed description

This is a 3-part study. A total of 204 subjects will be dosed in this study if Parts 2 and 3 are conducted.

In Part 1, in Period 1, a single dose of entinostat will be administered. In Period 2, multiple doses of omeprazole will be administered for 5 days with a single dose of entinostat co-administered. If preliminary results in Period 2 of Part 1 indicate that omeprazole exhibits clinically significant drug-drug interaction (DDI) with entinostat, then Parts 2 and 3 will be conducted. If no DDI interaction is concluded between entinostat and omeprazole in Part 1, then neither Part 2 nor 3 will be conducted.

Part 2 will investigate the effect of multiple doses of famotidine administration on entinostat PK. In Period 1, a single dose of entinostat will be administered. In Period 2, oral doses of famotidine with a single dose of entinostat co-administered.

Part 3 will evaluate the effect of an acidic beverage co-administered with entinostat in subjects with increased gastric pH due to omeprazole treatment. In Period 1, multiple oral doses of omeprazole will be administered with a single dose of entinostat co-administered with water. In Period 2, multiple doses of omeprazole will be administered with a single dose of entinostat co-administered with an acidic beverage.

In all parts, PK samples will be taken.

What is being measured

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

  1. AUC0-t (area under the concentration-time curve) for entinostat administered with or without omeprazole (Part 1), with or without famotidine (Part 2), or omeprazole with and without acidic beverage

    Measured: Pre-dose through Day 22

  2. AUC0-inf (area under the concentration-time curve, from time 0 extrapolated to infinity for entinostat administered with or without omeprazole (Part 1), with or without famotidine (Part 2), or omeprazole with and without acidic beverage (Part 3)

    Measured: Pre-dose through Day 22

  3. Cmax (maximum observed concentration) for entinostat administered with or without omeprazole (Part 1), with or without famotidine (Part 2), or omeprazole with and without acidic beverage (Part 3)

    Measured: Pre-dose through Day 22

Secondary outcomes (3)
  1. AUC%extrap (percent of AUC0-inf extrapolated) for entinostat administered with or without omeprazole (Part 1), with or without famotidine (Part 2), or omeprazole with and without acidic beverage (Part 3)

    Measured: Pre-dose through Day 22

  2. Tmax (time to reach maximum observed concentration) for entinostat administered with or without omeprazole (Part 1), with or without famotidine (Part 2), or omeprazole with and without acidic beverage (Part 3)

    Measured: Pre-dose through Day 22

  3. Kel (apparent terminal elimination rate constant) for entinostat administered with or without omeprazole (Part 1), with or without famotidine (Part 2), or omeprazole with and without acidic beverage (Part 3)

    Measured: Pre-dose through Day 22

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing entinostat, Omeprazole and Famotidine in people with Volunteers and Healthy Volunteers, run by Syndax Pharmaceuticals at 2 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 9 inclusion and 21 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 16 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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 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?

AUC0-t (area under the concentration-time curve) for entinostat administered with or without omeprazole (Part 1), with or without famotidine (Part 2), or omeprazole with and without acidic beverage (time frame: Pre-dose through Day 22). 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?
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 16 Aug 2018.
