• 1 other identifier: CR004150
• Study Type: interventional
• Target: 30
• Locations: 0 countries
• Sites: N/A

Brief Summary

The purpose of this study is to evaluate the effects of an organic cation transporter inhibitor, trimethoprim, on the pharmacokinetics of orally administered ER OROS paliperidone and to assess the safety and tolerability of the treatments in healthy male volunteers.

Conditions

Outcome Measures

Primary Outcomes (1)

• To evaluate the effects of an organic cation transporter inhibitor, trimethoprim, on the pharmacokinetics of orally administered ER OROS paliperidone

Secondary Outcomes (1)

Eligibility Criteria

• Age: 18 Years - 55 Years
• Sex: male
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• Male, aged 18 to 55 years, inclusive
• Volunteers must have signed an informed consent document indicating that they understand the purpose of and procedures required for the study and are willing to participate in the study
• Body Mass Index (BMI, weight \[kg\]/height \[m²\]) range of 18 to 28 kg/m², inclusive
• Normotensive with supine (5 minutes) blood pressure between the range of 100 to 140 mmHg systolic, inclusive, and 60 to 90 mmHg diastolic, inclusive
• Healthy on the basis of a prestudy physical examination, medical history, 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 subject can be included only if the investigator judges that the deviations are not clinically significant
• Creatinine clearance value greater than or equal to 80 mL/min
• Signed an informed consent for genetic testing, indicating whether the volunteer does or does not wish to participate in the genetic part of the study.

You may not qualify if:

• Drug allergy to risperidone, paliperidone, trimethoprim, any of its excipients or history of hypersensitivity to heparin, in case a heparin lock will be used
• Past or current history of folic acid deficiency or megaloblastic anemia
• Recent history of alcohol or substance abuse or dependence or a positive test result for the urine drug screen at screening
• Relevant history or presence of any cardiovascular (including myocardial infarct or cardiac arrhythmia), respiratory, neurological (including seizures, cerebrovascular disorders), psychiatric, renal, hepatic, gastrointestinal (including surgeries, severe gastrointestinal narrowing, and malabsorption problems), endocrinal, hematological or immunological disease. History of any cancer, with the exception of basal cell carcinomas
• At screening, has a 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 \<45 bpm) as determined by screening ECG
• A positive result for any of the tests for hepatitis B, C, and human immunodeficiency virus (HIV).
