January 8, 2025 6:48 am ET GARDASIL is the first HPV vaccine approved for the prevention of certain HPV-related cancers and diseases in Chinese males RAHWAY, N.J.--(BUSINESS WIRE)-- Merck (NYSE: MRK), known as MSD outside of the United States and Canada, today announced that the National Medical Products Administration (NMPA) of China approved GARDASIL ® [Human Papillomavirus Quadrivalent (Types 6, 11, 16, and 18) Vaccine, Recombinant] for use in males 9-26 years of age to help prevent certain HPV-related cancers and diseases. The approval makes GARDASIL the first HPV vaccine approved for use in males in China. GARDASIL is now indicated in China to prevent anal cancers caused by HPV Types 16 and 18, genital warts (condyloma acuminata) caused by HPV Types 6 and 11, and the following precancerous or dysplastic lesions caused by HPV Types 6, 11, 16, and 18: grade 1, grade 2, and grade 3 anal intraepithelial neoplasia (AIN). “The approval of GARDASIL for use in males 9-26 years old in China is a significant step forward in advancing public health,” said Joseph Romanelli, president, Human Health International, Merck. “Since first approval, our HPV vaccines have helped protect over 50 million females in China from certain HPV-related cancers and diseases. With this expanded approval, we look forward to helping protect this new population of Chinese males from certain HPV-related cancers and diseases.” Indications for GARDASIL 1 GARDASIL is a vaccine indicated in females 9 through 45 years of age. GARDASIL is indicated for the prevention of cervical, vulvar, vaginal, and anal cancers caused by HPV Types 16 and 18, precancerous or dysplastic lesions caused by HPV Types 6, 11, 16, and 18, and for the prevention of genital warts caused by HPV Types 6 and 11. GARDASIL is indicated in males 9 through 26 years of age. GARDASIL is indicated for the prevention of anal cancer caused by HPV Types 16 and 18, and precancerous or dysplastic lesions caused by HPV Types 6, 11, 16, and 18, and for the prevention of genital warts caused by HPV Types 6 and 11. GARDASIL does not eliminate the necessity for vaccine recipients to undergo screening for cervical, vulvar, vaginal, and anal cancers as recommended by a health care provider. GARDASIL has not been demonstrated to provide protection against diseases caused by: - HPV types not covered by the vaccine - HPV types to which a person has previously been exposed through sexual activity Not all vulvar, vaginal, and anal cancers are caused by HPV, and GARDASIL protects only against those vulvar, vaginal, and anal cancers caused by HPV Types 6, 11, 16 and 18. GARDASIL is not a treatment for external genital lesions; cervical, vulvar, vaginal, anal, oropharyngeal and other head and neck cancers; or cervical intraepithelial neoplasia (CIN), vulvar intraepithelial neoplasia (VIN), vaginal intraepithelial neoplasia (VaIN), or anal intraepithelial neoplasia (AIN). Vaccination with GARDASIL may not result in protection in all vaccine recipients. Select Safety Information for GARDASIL GARDASIL is contraindicated in individuals with hypersensitivity, including severe allergic reactions to yeast, or after a previous dose of GARDASIL. Because vaccinees may develop syncope, sometimes resulting in falling with injury, observation for 15 minutes after administration is recommended. Syncope, sometimes associated with tonic-clonic movements and other seizure-like activity, has been reported following HPV vaccination. When syncope is associated with tonic-clonic movements, the activity is usually transient and typically responds to restoring cerebral perfusion. Safety and effectiveness of GARDASIL have not been established in pregnant women. The most common (≥1.0%) adverse reactions were headache, fever, nausea, dizziness; and injection-site pain, swelling, erythema, pruritus, and bruising. The duration of immunity of GARDASIL has not been established. Dosage and Administration GARDASIL should be administered intramuscularly in the deltoid or anterolateral area of the thigh. For GARDASIL, a complete vaccination regimen for individuals 9 through 26 years of age consists of 3 doses at the following schedule: 0, 2 months, 6 months.

November 12, 2024 3:00 am ET RAHWAY, N.J.--(BUSINESS WIRE)-- Merck (NYSE: MRK), known as MSD outside of the United States and Canada, today announced that new clinical and real-world data for the company’s 9-valent Human Papillomavirus (HPV) vaccine, GARDASIL ® 9 (Human Papillomavirus 9-valent Vaccine, Recombinant), evaluating the burden and incidence of certain HPV-related cancers and diseases, will be presented at the International Papillomavirus Conference (IPVC) 2024 in Edinburgh, UK, from November 12-15. Data to be presented include results from the BROADEN and PROGRESS studies evaluating the prevalence of oral HPV infection and burden of HPV-related oropharyngeal and other head and neck cancers, as well as studies evaluating the age of disease-causal HPV infection among females and highlighting the importance of protecting both females and males from HPV-related cancers and diseases through vaccination. “These data support the value of adult vaccination and strengthen our understanding that disease-causal HPV infection can happen later in life, reinforcing the importance of HPV vaccination for both females and males beginning at age 9,” said Dr. Eliav Barr, senior vice president, head of global clinical development and chief medical officer, Merck Research Laboratories. “While historically the HPV vaccination conversation has focused on preventing certain HPV-related cervical cancers in women, we also continue to see the growing incidence of HPV-related oropharyngeal and other head and neck cancers, particularly in men. In both men and women globally, there are approximately 666,000 new diagnoses of certain HPV-related cancers annually. The breadth of data we are presenting at the conference continues to demonstrate the link between HPV and certain HPV-related cancers in males and females and the role HPV vaccination can play in prevention.” Details on key abstracts for Merck: New Data Analyses of HPV-Related Cancers and Diseases in Women and Men Abstract Title Details Immunogenicity Of 9-Valent HPV (9VHPV) Vaccine In Male Clinical Trial Participants: A Post-Hoc Analysis By Baseline Demographic Characteristics.

RAHWAY, N.J.--( BUSINESS WIRE )--Merck (NYSE: MRK), known as MSD outside of the United States and Canada, today announced positive top-line results from its pivotal Phase 3 trial (V503-064) evaluating the company’s 9-valent Human Papillomavirus (HPV) vaccine, GARDASIL ® 9 (Human Papillomavirus 9-valent Vaccine, Recombinant) in Japanese males ages 16 to 26 years. The trial met its primary and secondary endpoints demonstrating that administration of a 3-dose regimen of GARDASIL 9 reduced the combined incidence of anogenital persistent infection caused by 9 types of HPV compared with a placebo. “ A decade after the first approval of GARDASIL 9, Merck continues to evaluate this important vaccine in additional patient populations and remains committed to helping prevent certain HPV-related cancers through broad and equitable access globally,” said Dr. Eliav Barr, senior vice president, head of global clinical development and chief medical officer, Merck Research Laboratories. “ These data build on the clinical efficacy of GARDASIL 9 for the prevention of persistent infection in males and can potentially make a significant impact in addressing the global burden of certain HPV-related cancers and diseases.” Merck plans to share these data with regulatory authorities in Japan and other countries around the world to support licensure for use in males. The full results also will be presented at an upcoming scientific congress. The clinical development program evaluating GARDASIL 9 in males also includes an ongoing confirmatory Phase 3 trial evaluating efficacy in preventing HPV oral persistent infection to support effectiveness against HPV-related oropharyngeal and other head and neck cancers ( NCT04199689 ). About V503-064 V503-064 is a Phase 3, double-blind, placebo-controlled clinical study ( NCT04635423 ) to evaluate the safety/tolerability and efficacy of GARDASIL 9 (V503) in preventing HPV-related anogenital persistent infection in Japanese males 16 to 26 years of age. GARDASIL 9 is commercialized in Japan under the name SILGARD 9. The primary efficacy objective was to demonstrate reduction in the incidence of HPV 6/11/16/18-related 6-month anogenital persistent infection. The secondary efficacy objective was to demonstrate reduction in the incidence of HPV 31/33/45/52/58-related 6-month anogenital persistent infection. The study enrolled 1,059 participants.
