Elanco Launches Broad-Spectrum Canine Parasiticide

INDIANAPOLIS, Jan. 17, 2011 /PRNewswire/ — Elanco Companion Animal Health has
launched its second product in the new year with the launch of Trifexis(TM)
(spinosad + milbemycin oxime), a broad-spectrum parasiticide that kills fleas
and is indicated for the prevention and treatment of flea infestations, the
prevention of heartworm disease and the treatment and control of adult hookworm,
roundworm and whipworm infections in dogs and puppies 8 weeks and older, and 5
pounds of body weight or greater.

“Trifexis provides three types of parasite protection by combining two trusted
active ingredients, spinosad and milbemycin oxime, into a convenient, monthly
chewable tablet,” said Steve Connell, DVM, director of technical, academic and
consumer services for Companion Animal Health at Elanco. “It is a significant
addition to the portfolio of parasiticide products available to veterinarians
and pet owners. Trifexis is the fourth new product we have introduced in less
than four years, delivering the innovation we promised when we launched Elanco
Companion Animal Health.”

Approved by the FDA, Trifexis starts killing fleas within 30 minutes and was
100% effective in four hours in a controlled laboratory study.(1) Trifexis also
prevents heartworm disease caused by Dirofilaria immitis, and treats and
controls adult hookworm (Ancylostoma caninum), roundworm (Toxocara canis &
Toxascaris leonina) and whipworm (Trichuris vulpis) infections. The flavored
chewable tablet can be offered like a treat, providing convenience for dog
owners. It is available in five dosing sizes for dogs ranging from 5 to 120 lbs.
Dogs greater than 120 lbs. may be treated by administering an appropriate
combination of tablets.

The introduction of spinosad, one of the active ingredients in Trifexis,
resulted in the receipt of a Presidential Green Chemistry Challenge Award(2) in
1999 from the U.S. Environmental Protection Agency. The award was presented to
Dow AgroSciences LLC in the category of Designing Safer Chemicals for the
introduction of spinosad as an insect control product for use on crops. This
award demonstrates that spinosad as a technology for insect control has a
favorable environmental profile. This award is not relevant to the safety and
efficacy of Trifexis, nor does it confer any environmental benefit to Trifexis.

Trifexis is a prescription medication, available only through licensed
veterinarians. To reinforce dispensing within the context of a valid
veterinarian/client/patient relationship, all boxes and cartons of Trifexis
contain a unique product tracking code.

Trifexis is the third product in Elanco’s parasiticide portfolio. Comfortis®
(spinosad), the first FDA-approved, chewable beef-flavored tablet that kills and
prevents fleas for a full month, was launched in 2007. Comfortis quickly became
a valuable tool in the fight against fleas, particularly in the flea-endemic
Gulf Coast region of the U.S., where veterinarians have made Comfortis their No.
1 choice for dogs.(3) Assurity(TM), a topical flea treatment for cats, was
registered with the EPA and launched earlier in January.

Important safety information about Trifexis

Serious adverse reactions have been reported following concomitant extra-label
use of ivermectin with spinosad alone, one of the components of Trifexis
chewable tablets. Treatment with fewer than three monthly doses after the last
exposure to mosquitoes may not provide complete heartworm prevention. Prior to
administration of Trifexis, dogs should be tested for existing heartworm
infection. Use with caution in breeding females. The safe use of Trifexis in
breeding males has not been evaluated. Use with caution in dogs with
pre-existing epilepsy. Puppies less than 14 weeks of age may experience a higher
rate of vomiting. If vomiting occurs within an hour of administration, redose
with another full dose. The most common adverse reactions recorded during
clinical trials were vomiting, pruritus, lethargy and diarrhea. For product
label, including complete safety information, see attached.

Important safety information about Comfortis

The most common adverse reaction reported is vomiting. Other adverse reactions
reported in decreasing order of frequency are: depression/lethargy, decreased
appetite, incoordination, diarrhea, itching, trembling, excessive salivation and
seizures. Following concomitant extra-label use of ivermectin with Comfortis,
some dogs have experienced the following clinical signs: trembling/twitching,
salivation/drooling, seizures, incoordination, excessive dilation of pupils,
blindness and disorientation. Post-approval experience continues to support the
safety of Comfortis when used concurrently with heartworm preventatives
according to label directions. For product label, including complete safety
information, see attached label.
