Study Endpoints

Primary Endpoints

Titers of Anti-human Papilloma Virus 16 (Anti-HPV-16) and Anti-human Papilloma Virus 18 (Anti-HPV-18) Neutralizing Antibodies
At Month 7

Titers are displayed as Geometric Mean Titers (GMTs). The titer is the serum dilution giving a 50 percent reduction of the signal compared to a control without serum.

Secondary Endpoints

Titers of Anti-human Papilloma Virus 16 (Anti-HPV-16) and Anti-human Papilloma Virus 18 (Anti-HPV-18) Neutralizing Antibodies
At Month 6, 7, 12, 18, 24, 36, 48 and 60
Number of Subjects With Antibody Titers (Neutralizing Assay) Against Other Oncongenic HPV Types Greater Than or Equal to the Cut-off Value
At Month 7
Titers of Antibodies to Other Oncogenic HPV Types Measured by Neutralization Assay

Frequently asked questions about Gardasil

What is Gardasil used for?

Gardasil is a vaccine used for infections caused by papillomavirus, specifically human papillomavirus (HPV). It is indicated for the prevention of HPV infections. The drug was studied in healthy females aged 18 to 45 years in a clinical trial setting.

Who makes Gardasil?

Gardasil is developed by GSK plc, a biopharmaceutical company listed on the stock exchange under the ticker GSK. The company conducted a Phase 3 clinical trial to evaluate the vaccine's immunogenicity.

What phase is Gardasil in?

Gardasil is in Phase 3 clinical development. It has completed one Phase 3 trial, which was a randomized, double-blind, active-controlled study. The drug is investigational and not yet approved for use.

What clinical trials is Gardasil in?

Gardasil has been studied in one completed Phase 3 clinical trial, identified as NCT00423046. This trial evaluated the immunogenicity of GSK's HPV vaccine compared with Gardasil in healthy females aged 18 to 45 years in the United States.

Is Gardasil a monoclonal antibody?

Yes, Gardasil is classified as a monoclonal antibody. It is being developed for the prevention of papillomavirus infections, which are a cause of various diseases. The drug is administered as a vaccine to elicit an immune response.

How does Gardasil work?

Gardasil is a monoclonal antibody that targets human papillomavirus (HPV). It works by stimulating the immune system to produce a protective response against HPV infections, thereby preventing the infections and associated diseases. The exact mechanism involves the antibody's interaction with viral components.
