PHASE2

A Clinical Study of V540A in Healthy Female Participants (V540A-005)

Sponsor: Merck Sharp & Dohme LLC

View on ClinicalTrials.gov

Summary

Researchers are looking for new ways to prevent cancers related to human papillomavirus (HPV). HPV is a common virus that can cause an infection. There are many different types of HPV. A standard vaccine to prevent HPV-related cancers is V503. V503 protects against 9 types of HPV. V540A is a study vaccine designed to protect against the same (shared) 9 HPV types plus other (unique) HPV types. Researchers want to learn if V540A: * Is safe and if people tolerate it * Works as well as V503 to cause an immune response (the body's response to protect against infections and illnesses) to the shared HPV types.

Official title: A Phase 2, Randomized, Double-Blind, Comparator-Controlled Study to Evaluate the Safety, Tolerability, and Immunogenicity of V540A in Healthy Females 16 to 26 Years of Age
