"This agreement recognizes the tremendous progress that scientists and clinicians at the Instituto Butantan have made in developing their investigational dengue virus vaccine"

KENILWORTH, N.J.--(BUSINESS WIRE)--Merck (NYSE:MRK), known as MSD outside the United States and Canada, and Instituto Butantan, Sao Paulo, Brazil, a non-profit producer of immunobiologic products for Brazil today announced a collaboration agreement to develop vaccines to protect against dengue virus disease, the mosquito-borne infection. Instituto Butantan and Merck have licensed certain rights from National Institute of Allergy and Infectious Diseases (NIAID), part of the United States National Institutes of Health (NIH), for the development of live attenuated tetravalent vaccines (LATV). Instituto Butantan’s dengue vaccine candidate, TV003, is currently being evaluated in a large Phase 3 study in Brazil.

“By sharing data from our ongoing vaccine development programs, Instituto Butantan and Merck are better positioned to achieve our goal of reducing the significant human and economic toll of dengue virus in Brazil and around the world,” said Dr. Dimas Covas, director, Instituto Butantan. “We look forward to collaborating with Merck, an established global leader in vaccine development.”

Under the agreement, Merck and Instituto Butantan have agreed to collaborate to share clinical data and other learnings from their respective dengue vaccine development programs, both derived from licensed materials from the NIAID. Instituto Butantan will receive a $26 million upfront payment from Merck and is eligible to receive up to $75 million for the achievement of certain milestones related to the development and commercialization of Merck’s investigational vaccine as well as potential royalties on sales. Instituto Butantan will retain responsibility for the manufacturing and commercialization of their investigational vaccine, TV003, in Brazil.

“This agreement recognizes the tremendous progress that scientists and clinicians at the Instituto Butantan have made in developing their investigational dengue virus vaccine,” said Dr. Roger M. Perlmutter, president, Merck Research Laboratories. “Through our new collaboration, we together have made a commitment to help protect people around the world who are at risk of developing dengue virus disease.”

The agreement builds upon a productive long-term collaboration between MSD Brazil and Instituto Butantan, initiated in 2012, for human papillomavirus (HPV) and Hepatitis-A vaccine products.

About dengue fever

Dengue fever is a mosquito-borne disease that occurs in tropical and subtropical areas of the world. Mild dengue fever is characterized by a high fever, rash, and muscle and joint pain. A severe form of dengue fever, (dengue hemorrhagic fever) can cause severe bleeding, a sudden drop in blood pressure and death. The World Health Organization has estimated that up to 400 million dengue infections occur annually, resulting in 500,000 hospitalizations.

About the dengue LATV candidate

Scientists in the Laboratory of Infectious Diseases at the NIAID of the NIH engineered a candidate live attenuated tetravalent vaccine against the dengue virus. NIAID then supported the development of the candidate vaccine through a series of clinical trials.

Instituto Butantan is sponsoring a placebo-controlled, double blind, multi-center Phase 3 trial evaluating a single dose of LATV produced at the institute in Sao Paulo. The Phase 3 trial aims to enroll almost 17,000 healthy people aged 2 to 59 years in 15 cities. All participants will be monitored for five years through a combination of in-person visits to the health clinic and telephone or text communications from the investigators. The goal of the trial is to determine the efficacy of the vaccine for preventing dengue, and importantly to provide additional information about its safety. The principal investigator is Dr. Esper Kallas, for the University of Sao Paolo.

Additional information about the trial is available at https://clinicaltrials.gov using the identifier NCT02406729.
