Safety and Immunogenicity Study of Prophylactic Streptococcus Pneumoniae Vaccine

Completed · Phase 1 · Has a placebo group

Conditions studied: Streptococcus Pneumoniae

In brief

GEN-004 is a combination of 3 conserved proteins from Streptococcus pneumoniae. This is a randomized, double-blind, placebo-controlled, dose escalation study. Eligible subjects (male and non-pregnant female) will be assigned sequentially to 1 of 3 dose cohorts and randomized in a 3:1:1 ratio to receive GEN-004 with adjuvant, GEN-004 without adjuvant, or placebo, respectively. Each subject will receive up to 3 doses at 4 week intervals. Subjects will be followed for safety, tolerability, and immunogenicity for 12 months after their last dose.

• Other active, uncontrolled co-morbidities that, in the opinion of the Investigator would make the subject unsuitable for the study or unable to comply with the study requirements.
• NOTE: Subjects who are taking a medication to control an underlying co-morbidity may be enrolled if there have been no changes to their medication within 60 days prior to the first dose of Study Drug.
• Any acute illness including, fever (>100.4 degrees F [> 38 degrees C]) within 3 days prior to the first dose of Study Drug.
