Maintenance Dose Study of GEN-003 in Subjects With Genital Herpes Infection

This study is a randomized, double-blind, placebo-controlled clinical trial of GEN-003 in subjects who have received previous doses of GEN-003 in the GEN-003-003 clinical trial. Eligible subjects will be randomized in a 1:1 ratio to receive 1 intramuscular (IM) dose (the maintenance dose) of GEN-003 or placebo. Subjects will use a daily electronic reporting tool for reporting the presence or absence of genital herpes lesions, and severity of genital herpes symptoms. GEN-003-005 was originally designed to follow subjects for 12 months after the maintenance dose but a business decision, unrelated to product safety, was made by Genocea Biosciences in 3Q2017 to cease GEN-003 spending and activities.
