Official title
A Phase 1/2, First-Time-in Human (FTiH), Randomized, Observer-blind, Placebo-controlled, Dose Escalation Study to Assess Safety, Reactogenicity and Immunogenicity of a Candidate Cytomegalovirus (CMV) Vaccine Comprising Recombinant Protein and Adjuvant When Administered Intramuscularly in Healthy Adults
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to assess the safety, reactogenicity and immune response of the candidate CMV recombinant protein subunit (CMVsu) vaccine consisting of a combination of glycoproteins B (gB) and pentamer antigens adjuvanted, regardless of baseline CMV sero-status. This FTiH study is conducted in healthy adults 18 to 50 years of age, in which the 4 dose levels of the vaccine are administered in a step-wise dose escalation manner, based upon safety adjudication.
