Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 to 55 years
- Men only
- Healthy volunteers accepted
- Adult
Who may be able to join
- Body mass index (weight [kg]/height [m2]) of 18 to 30 kg/m2, inclusive
- Extensive metabolizer of CYP2D6. Volunteers whose CYP2D6 genotype is unknown should have been phenotyped before the start of the study using dextromethorphan as a probe (i.e., have a dextromethorphan metabolic ratio <0.02, as determined according to the standard procedures of the study center)
- Have a supine (after 5 minutes rest) blood pressure between 100 and 140 mmHg systolic, inclusive, and 50 and 90 mmHg diastolic, inclusive
- Smokes no more than 10 cigarettes, or 2 cigars, or 2 pipes per day and has been following this pattern for at least 3 months before screening
- Healthy on the basis of a prestudy physical examination, medical history, 12-lead ECG, and the laboratory results of serum chemistry, hematology, and urinalysis performed within 21 days before the first dose. If the results of the serum chemistry, hematology, or urinalysis testing are not within the laboratory's reference ranges, the volunteer can be included only if the investigator judges that the deviations are not clinically significant. For renal function tests, the values must be within the normal laboratory reference ranges
Who cannot join
- Poor or intermediate metabolizers of CYP2D6, as determined by genotyping or phenotyping using dextromethorphan
- Known drug allergy to risperidone, paliperidone, paroxetine, or any of their excipients
- Known history of drug-induced dystonia
- Recent history of alcohol or substance abuse
- Relevant history or presence of any cardiovascular (including myocardial infarct or cardiac arrhythmia), respiratory, neurologic (including seizures), psychiatric, renal, hepatic, gastrointestinal (including surgeries, severe gastrointestinal narrowing, and malabsorption problems), endocrine, hematologic, or immunologic disease
- History of any cancer, with the exception of basal cell carcinoma
Show all 9Show fewer
- At screening, has signs of autonomic dysfunction as indicated by a sustained decrease of >20 mmHg in systolic blood pressure or a decrease of >10 mmHg in diastolic blood pressure after standing for at least 2 minutes that is not associated with an increase of >15 beats per minute (bpm) in heart rate
- Bradycardia (heart rate <50 bpm) as determined by screening 12-lead ECG
- A positive test result (or history of) for any of the serology tests (hepatitis B and C, and human immunodeficiency virus) at screening
About this study
Official title: A Randomized, Open-label, Single-center, Crossover Study of the Potential Effects of Paroxetine on the Pharmacokinetics of a Single Dose of Paliperidone Extended-release in Healthy Men
The purpose of this study is to evaluate the effects of a CYP2D6 inhibitor, paroxetine, on the pharmacokinetics of a single dose of orally administered paliperidone ER and to evaluate the safety and tolerability of both treatments in healthy men
Read the detailed description
This is a randomized, open-label, single-center, single-dose, 2 treatment, 2 way crossover study. It consists of 3 phases: a screening phase beginning within 21 days before the first study drug administration; an open label treatment phase consisting of 2 treatment periods (Period 1 and Period 2), during which patients will receive 2 single doses of 3 mg paliperidone ER; and end of study evaluations upon completion of all the study procedures in Period 2 or at early withdrawal. All volunteers will receive each of the following 2 treatments in random order: Treatment A: 1 tablet of 3 mg paliperidone ER in the fasted state; Treatment B: one 20 mg paroxetine tablet once a day from Day 1 to Day 13 and 1 tablet of 3 mg paliperidone ER on Day 10 in the fasted state. Successive paliperidone ER administrations will be separated by a washout period of at least 14 days and no more than 28 days. Paroxetine is a potent and selective CYP2D6 inhibitor. Inhibitors of CYP2D6 such as paroxetine have been reported to increase the plasma concentrations of antipsychotics such as perphenazine, clozapine, and risperidone. Because paliperidone ER and paroxetine could potentially be used in combination in schizophrenic patients, the potential for a drug-drug interaction between paroxetine and paliperidone ER needs to be explored.The safety and tolerability of the 3 mg tablet of paliperidone ER administered with and without paroxetine to healthy men will be monitored.
Two single oral doses of paliperidone ER 3-mg; 20-mg paroxetine orally once a day for 13 days

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Paliperidone ER in people with Schizophrenia, run by Johnson & Johnson Pharmaceutical Research & Development, L.L.C..
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 5 inclusion and 9 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 19 May 2011. Status can change between updates, so confirm with the study contact before making plans.
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 effects of a CYP2D6 inhibitor, paroxetine, on the pharmacokinetics of a single dose of orally administered paliperidone ER. 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 19 May 2011.
