MSD Animal Health Receives Marketing Approval from European Medicines Agency for BRAVECTO™ (fluralaner) Spot-On Solution for Cats and Dogs

Spot-On Treatment for Fleas and Ticks Effective For 12 Weeks

MADISON, N.J.–(BUSINESS WIRE)–$MRK #MSD–MSD Animal Health (known as Merck Animal Health in the United States and
Canada) today announced that, following a positive opinion from the
Committee for Medicinal Products for Veterinary Use (CVMP), the European
Medicine Agency has granted a marketing authorization for the veterinary
medicinal product BRAVECTO™ (fluralaner) Spot-On Solution for both cats
and dogs, a Spot-On treatment for fleas and ticks effective for 12 weeks
following a single dose.

BRAVECTO Spot-On, a systemic insecticide and acaricide, is indicated for
the treatment of tick and flea infestations on cats and dogs and
provides immediate and persistent flea and tick killing activity for 12
weeks. BRAVECTO Spot-On is applied topically using the new
“Twist’n’Use”™ pipette design for ease of application. Detailed
conditions of the product will be described in the summary of product
characteristics (SPC) which will be published in the European public
assessment report (EPAR).

“Approval of BRAVECTO Spot-On builds on the strong foundation and body
of scientific evidence that we have established with our chewable tablet
for dogs, the oral flea and tick product available today,” said KJ
Varma, senior vice president, research & development, MSD Animal Health.
“BRAVECTO Spot-On now provides veterinarians and cat owners another tool
in the fight against parasites and gives veterinarians and dog owners a
choice in how to administer flea and tick protection that works quickly
and lasts up to twelve weeks.”

In 2014, BRAVECTO was launched as a chewable tablet for dogs. More than
13 million doses of the BRAVECTO chew have been dispensed in 60
countries since its introduction.

Fleas and ticks must attach to the treated animal and commence feeding
in order to be exposed to the active substance. The most common side
effects of BRAVECTO Spot-On in dogs are mild and transient skin
reactions such as erythema or alopecia at the application site and, in
cats, pruritus at the application site. The product can be used as part
of a treatment strategy for the control of Flea Allergy Dermatitis
(FAD). The most common side effects of BRAVECTO chewable tablet
administration to dogs are mild and transient gastrointestinal effects.

BRAVECTO Spot-On will be available in countries throughout Europe in the
coming months. Veterinarians interested in learning more about BRAVECTO
Spot-On should contact their MSD Animal Health representative.
