Overview
Brief Summary
This is a randomised and single-blind, placebo-controlled study to investigate the safety, tolerabilty, pharmacokinetics and pharmacodynamics of repeated and ascending doses of AZD2820 to obese but otherwise healthy male subjects.

Investigators
Eligibility Criteria
Inclusion Criteria
- •Provision of signed and dated, written informed consent prior to any study specific procedures including the genetic sampling and analyses
- •Obese but otherwise healthy male subjects aged 18 - 45 years with suitable veins for cannulation or repeated venepuncture
- •Male subjects should be willing to use barrier contraception ie, condoms, from the first day of dosing until 3 months after the last dose of investigational product
- •Have a body mass index (BMI) between 27 and 40 kg/m2
Exclusion Criteria
- •History of any clinically significant disease or disorder which, in the opinion of the investigator, may either put the subject at risk because of participation in the study, or influence the results or the subject's ability to participate in the stud
- •A history of erectile dysfunction or anatomic abnormality of the penis (eg, cavernosal fibrosis, Peyronie's disease, or plaques) which interferes with normal erectile function
- •Prolonged QTcF \>450 ms or shortened QTcF \<340 ms or family history of long QT syndrome
- •History of severe allergy/hypersensitivity or ongoing allergy/hypersensitivity, as judged by the investigator or history of hypersensitivity to drugs with a similar chemical structure or class to AZD2820
- •Any clinically significant abnormalities in clinical chemistry, haematology (including eosinophilia) or urinalysis results as judged by the investigator
