MSD Animal Health Wins 2024 S&P Global Award for Best New Companion Animal Product for injectable formulation of BRAVECTO® (fluralaner)

Parasiticide Treatment for Dogs Offers Unrivaled Duration of Flea and Tick Protection Compared to Existing Products

Rahway, N.J., February 11, 2025 – MSD Animal Health, a division of Merck & Co., Inc., Rahway, N.J., USA (NYSE:MRK), today announced that S&P Global Animal Health awarded the injectable formulation of BRAVECTO® (fluralaner) the 2024 Best New Companion Animal Product. It is the first and only parasiticide that protects dogs against fleas and ticks for an entire year with a single dose, offering longer flea and tick protection than any other systemic product currently on the market.

The injectable formulation of BRAVECTO was first approved in Australia and New Zealand in 2023, followed by the Europe Union in 2024. In total, the injectable formulation of BRAVECTO is currently approved in more than 30 countries worldwide. The product is not yet approved in the United States as of February 2025.

The unique formulation allows for effective levels of fluralaner to be maintained for as long as 12 months. Many ticks can live in both warm and cold temperatures and are known to feed on dogs,[i] making continuous year-round protection of utmost importance for pets and people. Certain ticks can transmit serious infections .

“We take great pride in our ongoing recognition as a leader in animal health,” said Rick DeLuca, president, MSD Animal Health. “Our dedicated people—spanning research and development, commercial operations, manufacturing, and sales—consistently strive to advance The Science of Healthier Animals for our customers. The injectable formulation of BRAVECTO continues our leadership in long-acting preventative parasiticides and exemplifies our commitment to groundbreaking science that will serve both the veterinary community and pet owners.”

Since its introduction in 2014, BRAVECTO has provided long-lasting flea and tick protection, with more than 350 million doses distributed in more than 100 countries. BRAVECTO is available in a variety of formulations, including tablets, chews, and topical solutions. The safety and efficacy of this novel injectable formulation has been evaluated in numerous laboratory and clinical field studies around the world in support of the global regulatory approvals.

“Innovation lies at the heart of our diverse portfolio of parasiticides,” said Frank Guerino, associate vice president of Pharmaceutical Research and Development, MSD Animal Health. “Our company is committed to understanding the specific needs of the companion animal industry, and we align our research and development efforts to deliver effective solutions for unmet needs. With this injectable formulation of BRAVECTO, we are proud to offer an innovative product, which puts parasite control in the hands of veterinarians, thus eliminating potential compliance gaps caused by pet owner failure to administer monthly products at the proper time interval.”

“MSD Animal Health has continued to bring differentiated products like this novel injectable formulation to the market,” said Joseph Harvey, head of S&P Global Animal Health. “The company continues to build its reputation by winning awards in both Companion Animal and Food Animal categories over many years, which is a testament to its innovation and customer focus within the industry.”

This award marks the second time that the company is honored in this category. In 2015, the company won Best Product Pipeline and Best New Companion Animal Product for the Canine Influenza Vaccine H3N2. Previously, the company has won for the sixth straight year in the Best New Food Animals category for the IDAL® portfolio technology, PORCILIS® Lawsonia intramuscular vaccine for piglets, NOBILIS® SALENVAC ETC, WHISPER® ON ARRIVAL, SENSEHUB® Feedlot and CIRCUMVENT® CML. Additionally, MSD Animal Health was named Best Animal Health Company, North America in 2021, and Best Visionary CEO for Rick DeLuca in 2020.

About BRAVECTO®

Since its introduction in 2014, BRAVECTO has provided longer-lasting flea and tick protection, with more than 350 million doses distributed in 100 countries over eight years. BRAVECTO is available in a variety of formulations, including products for both dogs and cats.

The flea lifecycle can last as long as 12 weeks, and monthly treatments may leave gaps in protection. Providing pets with continuous flea and tick protection is essential – whether the pet goes outside or not. Contrary to popular belief among pet owners, fleas and ticks are not only active in the spring and summer months and are a year-round risk. Fleas and ticks can easily latch onto dogs and cats, and can spread serious diseases. Fleas are the most common external parasite found on pets. BRAVECTO products are only available through licensed veterinarians.
