About this study

Official title: A Phase 1, Open-Label, Two-Period, Fixed-Sequence, Drug-Drug Interaction Study to Evaluate the Pharmacokinetics and Safety of CTX 4430 and Midazolam in Healthy Adult Subjects

This drug-drug interaction study will assess the potential of CTX-4430 to induce CYP3A activity in healthy subjects.

The study hypothesis is that midazolam (a sensitive, widely used CYP3A4 substrate) blood levels will not change after treatment with CTX-4430.

What is being measured

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

  1. To evaluate the change in maximum plasma concentration (Cmax) and area under the curve (AUC) for both midazolam and 1-OH-midazolam after 7 days of treatment with CTX-4430

    Measured: 10 days

Secondary outcomes (2)
  1. To evaluate the safety and tolerability of the administration of single oral doses of midazolam, both in the absence and presence of multiple dose CTX-4430.

    Safety and tolerability assessments include Adverse Event monitoring, Physical Examinations, Vital Sign assessments (heart rate, blood pressure, respiratory rate and temperature), Pulse Oximetry assessments, ECG assessments and Pregnancy testing in female subjects.

    Measured: 10 days

  2. To evaluate the safety and tolerability of multiple oral doses of CTX-4430.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CTX-4430 and Midazolam in people with Healthy, run by Celtaxsys, Inc. at 1 site in United Kingdom.

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 19 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 10 Oct 2014. 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 Kingdom. 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?

To evaluate the change in maximum plasma concentration (Cmax) and area under the curve (AUC) for both midazolam and 1-OH-midazolam after 7 days of treatment with CTX-4430 (time frame: 10 days). 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 10 Oct 2014.
