Brief Summary:
The primary purpose is to study the occupancy at the α4β2 neuronal nicotinic receptor's (NNRs) and to determine the relation between plasma concentration of AZD1446 and the occupancy at α4β2 NNRs.

Condition or disease Intervention/treatment Phase
Healthy Drug: AZD1446 Radiation: 2-[18F]-F-A85380 Phase 1

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 11 participants
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Official Title: An Open-label Positron Emission Tomography (PET) Study Using 2 [18F] F A85380 to Determine α4β2 Neuronal Nicotinic Receptor (NNR) Occupancy of AZD1446 After Oral Administration to Male and Non-fertile Female (Non-nicotine Users) Healthy Volunteers
Study Start Date : April 2009
Actual Primary Completion Date : August 2009
Actual Study Completion Date : August 2009

Arm Intervention/treatment
Experimental: 2-[18F]-F-A85380
Single microdose
Radiation: 2-[18F]-F-A85380
iv, single dose
Experimental: AZD1446
Single oral administration
Drug: AZD1446
Solution, oral, single dose

Primary Outcome Measures :
  1. Determine whether and to what extent AZD1446 can displace radioligand 2-[18F]-F-A85380 from binding to α4β2 neuronal nicotinic receptors (NNRs) and to describe the relationship between plasma concentrations of AZD1446 and its occupancy at α4β2 NNRs. [ Time Frame: One PET assessment on baseline day and one PET assessment at the drug treatment day ]
  2. Plasma concentration (Cmax, tmax, AUC) [ Time Frame: During time period of the PET assessment ]

Secondary Outcome Measures :
  1. Safety and tolerability (AEs, vital signs, lab) [ Time Frame: During the whole study ]
