Experimental Human Infection With Neisseria Gonorrhoeae (LptA Trial)

NCT04870138

Non-randomizedParallel-groupOpen-labelBasic science

Summary

This is a Phase 1, interventional, non-randomized, experimental infection model study in healthy adult males (N=up to 25) between the ages of 18-35 at study enrollment. The study is designed to test the requirements of predicted N. gonorrhoeae virulence determinants for gonococcal infection in the male urethra through infection with engineered mutants of N. gonorrhoeae. We predict that mutations abolishing expression of N. gonorrhoeae virulence determinants will eliminate or significantly reduce gonococcal infectivity or the ability to induce inflammation in an infected individual, thus identifying potential vaccine candidates. Study duration will be 1 year, and the duration for all participants will be about 3 weeks. The primary objective of the study is to compare the ability of different engineered mutants of Neisseria gonorrhoeae to cause a clinical infection (signs or symptoms of urethritis such as discomfort during urination, urethral discharge, etc.) in the male urethra.
