Safety, Tolerability, Pharmacodynamic and Pharmacokinetics of a Single Rectal Application of 10 mg NRL001 in Elderly Subjects

• Status: Completed
• Trial end date: 2010-07-01
• Target enrollment: 0
• Participant gender: All

Summary

A total of 26 healthy elderly male and female subjects will receive both 10 mg NRL001 in a 2 g rectal suppository and placebo in this double-blind, cross-over study. The order of treatment will be randomised, with a minimum washout period of 3 days between doses. An end of study assessment will be conducted at least 7 days after administration of the last treatment.

The pharmacokinetics of NRL001 will be determined prior to, and after, dosing. Pharmacodynamics will be examined using a three lead Holter monitor during both treatment periods. Adverse Events, vital signs, ECGs and clinical laboratory parameters will be collected, tabulated, reviewed and recorded throughout the study.

• Clinically relevant ECG-abnormalities (e.g. QTc prolongation, acute arrhythmia) during the screening assessment

• Laboratory values which are abnormal and deemed to be clinically significant according to Bio-Kinetic Europe Ltd. SOPs, unless agreed in advance by the Sponsor's Responsible Medical Officer and the Bio-Kinetic Investigator.

• Current or history of drug or alcohol abuse or a positive drugs of abuse test at screening or check in.

• Use of any disallowed concomitant medication, including over-the-counter items within 14 days prior to study drug administration until the end of the study.

• Use of any medication applied via the rectum, within 30 days prior to dosing

• Use of any medication currently or within 30 days prior to dosing which the Investigator believes may affect the study participation or results.

• Participation in a clinical drug study during the 90 days preceding the initial dose in this study.

• Donation of blood or blood products within 90 days prior to study drug administration, or at anytime during the study, except as required by this protocol.
