Study Details
Study Description
Brief Summary
The main objective of the study is to determine the safety and tolerability of repeated application of PSD502 to the glans penis in healthy male volunteers

| Phase 1 |
Detailed Description
This is a phase I, double-blind, stratified, parallel group, placebo-controlled repeat dose study in a minimum of 8 circumcised and 8 uncircumcised healthy male volunteers. Subjects will attend 2 study visits, of which 1 will be a Screening Visit (Visit 1) and the other, a consecutive 21-day treatment visit (Visit 2; Days 1-21) which commences no more than 14 days after the Screening visit. Subjects will reside in the phase I unit throughout the treatment period. The duration of each subject's participation in the study will be up to 5 weeks.
Subjects are stratified based on whether they are circumcised or uncircumcised and within each stratified group subjects are randomized to PSD502 (lidocaine prilocaine spray) or placebo in a 3:1 ratio.
Procedures during the 21 day treatment period include: visual examination of the glans penis, blood sample collection for pharmacokinetic analysis of lidocaine and prilocaine, swabbing of the glans penis for residual PSD502, vital signs and 12-lead ECG, adverse event enquiries and collection of concomitant medications. Subjects are discharged from the clinic on Day 21 following a safety evaluation.
