This study has been completed.
Information provided by:
Orion Corporation, Orion Pharma Identifier:
First received: December 11, 2008
Last updated: November 23, 2009
Last verified: November 2009
The purpose of the study is to evaluate the effect of ORM-12741 on receptor occupancy by positron emission tomography with different doses and plasma concentrations. The pharmacokinetic profile and safety will also be evaluated.

Condition Intervention Phase
Healthy Drug: ORM-12741 Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Official Title: Effect of ORM-12741 on Receptor Occupancy Studied by Positron Emission Tomography; an Open, Single Dose, Dose Ranging Study in Healthy Males

Further study details as provided by Orion Corporation, Orion Pharma:

Primary Outcome Measures:
  • Receptor occupancy [ Time Frame: 1 day ]

Secondary Outcome Measures:
  • Pharmacokinetic variables including peak concentration in plasma, time to peak concentration, area under the plasma concentration-time curve [ Time Frame: 1 day ]
  • Safety variables including blood pressure, heart rate, electrocardiogram, physical examination, laboratory safety variables (haematology, chemistry, serology, urinanalysis) and adverse events. [ Time Frame: During the study ]

Enrollment: 26
Study Start Date: January 2009
Study Completion Date: June 2009
Primary Completion Date: June 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions

Drug: ORM-12741
Single dose as a capsule, oral administration


Ages Eligible for Study:   18 Years to 45 Years   (Adult)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Good general health ascertained by detailed medical history and physical examination
  • Males between 18 and 45 years
  • Body mass index (BMI; weight/height2) between 18-30 kg/m2
  • Weight 55-95 kg

Exclusion Criteria:

  • Evidence of clinically significant cardiovascular, renal, hepatic, haematological, gastro-intestinal, pulmonary, metabolic-endocrine, neurological, urogenital or psychiatric disease as judged by the investigator
  • Any condition requiring regular concomitant medication including herbal products or likely to need any concomitant medication during the study
  • Regular consumption of more than 21 units of alcohol per week (1 unit = 4 cl spirits, about 13 g of alcohol).
  • Current use of nicotine-containing products more than 5 cigarettes or equivalent/day
  • Inability to refrain from using nicotine-containing products during the stay at the study centre
  • Inability to refrain from consuming caffeine-containing beverages during the stay at the study centre e.g. propensity for headache when refraining from caffeine-containing beverages
  • Blood donation or loss of significant amount of blood within 3 months prior to the screening visit
  • Abnormal 12-lead electrocardiogram (ECG) finding of clinical relevance
  • Any abnormal value of laboratory, vital signs, or physical examination, which may in the opinion of the investigator interfere with the interpretation of the test results or cause a health risk for the subject if he takes part into the study
  • Anatomical abnormality in brain MRI which may in the opinion of the investigator interfere with the interpretation of the PET results
  • Participation in another clinical drug study within 3 months prior to the start of this study or earlier participation in a clinical study with ORM-12741
  • Participation in a prior PET study
  • Any contraindication to MRI of the brain
