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

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.
