Acceptable forms of birth control include abstinence and any double combination of: hormonal contraceptive, intrauterine device (IUD), male or female condom, diaphragm, sponge, and cervical cap. Spermicides may be used, but is not considered one of the required double barrier methods. All premenopausal female subjects (regardless of whether they are surgically sterile) must have a negative serum pregnancy test at screening and baseline.

Who cannot join

  • Known hypersensitivity or allergy to omeprazole, tolbutamide, dextromethorphan, midazolam, or CT1812
  • Absence of one functional allele for CYP2D6, CYP2C9 or CYP2C19 at screening
  • Any disease or condition (medical or surgical) which, in the opinion of the Investigator, might compromise the hematologic, cardiovascular, pulmonary, renal, gastrointestinal, hepatic, or central nervous system; or other conditions that may interfere with the absorption, distribution, metabolism or excretion of study drug, or would place the subject at increased risk
  • The presence of abnormal laboratory values which are considered clinically significant
  • Positive screen for Hepatitis B (HbsAg, Hepatitis B Surface Antigen), Hepatitis C (anti HCV, Hepatitis C Antibody), or HIV (anti-HIV 1/2)
  • Received an investigational drug within a period of 30 days prior to enrollment in the study
Show all 12Show fewer
  • Received any drug therapy within 2 weeks prior to administration of the first dose of any study-related treatment. This exclusion is extended to 4 weeks for any drugs known to induce or inhibit hepatic drug metabolism.
  • Consumption of alcohol within 14 days prior to dose administration or during any in-patient period
  • A positive urine drug screen including ethanol, cocaine, THC, barbiturates, amphetamines, benzodiazepines, and opiates
  • Any history of alcohol abuse, illicit drug use, significant mental illness, physical dependence to any opioid within the past two years, or any history of drug abuse or addiction within the past two years
  • A history of difficulty with donating blood
  • Donated whole blood within 45 days or blood products within 7 days prior to enrollment.

About this study

Official title: A Fixed-Sequence Trial to Examine the Effect of Multiple-Dose CT1812 Administration on Standard Probes of CYP2C19 (Omeprazole), CYP2C9 (Tolbutamide), CYP2D6 (Dextromethorphan), and CYP3A4/5 (Midazolam) Activity in Healthy Adult Volunteers

This is Phase 1, single-center, open-label, single-sequence drug-drug interaction study to determine the effect of CT1812 (560 mg) once daily on the pharmacokinetics of 4 probe drugs (tolbutamide, midazolam, dextromethorphan and omeprazole).

Read the detailed description

This is Phase 1, single-center, open-label, single-sequence drug-drug interaction study to determine the effect of CT1812 (560 mg) once daily on the pharmacokinetics of 4 probe drugs (tolbutamide, midazolam, dextromethorphan and omeprazole).

Each subject will qualify for entry into the study within 35 days before admission to the clinical unit. Subjects will check into the clinical unit on Day -3 for baseline assessments. Each subject will receive a single dose of each of the probe drugs on Day -2 as a 'cocktail'. A single dose of CT1812 and each of the probe drugs will be co-administered on Day 6. On Days 1 through 5, subjects will receive a single daily dose of CT1812.

Being tested
CT1812, tolbutamide, dextromethorphan, Omeprazole, midazolam

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CT1812, tolbutamide and dextromethorphan in people with Healthy Volunteers, run by Cognition Therapeutics 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 10 inclusion and 12 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 23 Oct 2018. 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?

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 time curve of CT1812 (Day 6) compared to the baseline values (Day -2) (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 23 Oct 2018.
