Parvovirus in Dogs


KIND-030 – Parvovirus in dogs

KIND-030, a monoclonal antibody targeting canine parvovirus (CPV), is being pursued for two indications: Prophylactic therapy to prevent clinical signs of CPV infection, and treatment of established CPV infection.

Positive results from pivotal efficacy study for the prophylactic indication. All placebo-control dogs developed parvovirus infection, while none of the KIND-030 dogs developed the disease. Mortality benefit in treated group also observed.

Prevalence

CPV is the most significant cause of enteric virus infecting dogs worldwide. Puppies between 10 and 12 weeks of age are particularly vulnerable to CPV because the protective effect of their maternally derived antibodies wanes or there is lack of response to immunization due to maternal antibody interference.¹ Banfield medical records estimate there are approximately 250,000 CPV cases in the United States each year, excluding emergency rooms, shelters, or undiagnosed cases. This does not include the other puppies and dogs that are potentially exposed to the virus.²

Disease Burden

Despite 40 years of research, there remains a high unmet medical need for an effective targeted therapeutic for CPV. There are currently no approved or unapproved treatments for CPV, and mortality rates are reportedly as high as 91% if untreated. Today, management of CPV infection is largely supportive.^3,4 Owners spend up to thousands of dollars per puppy in supportive care for CPV, with average cost of $1,200. If approved, KIND-030 would work in conjunction with vaccination protocols and would not replace the need for vaccination.

Cost Burden

Hospitalization is generally recommended,⁵ which can be cost prohibitive for some owners.⁶ Within a veterinary practice, treating CPV infection requires implementation of strict isolation and decontamination protocols to minimize spread of the virus, which adds to the cost of treatment.⁷ Despite 40 years of research, there remains a high unmet medical need for an effective targeted therapeutic for CPV.

Near-term Catalysts

Completion of the pivotal efficacy study for the treatment of established parvovirus infection is expected in the second quarter of 2021. KindredBio expects potential approval of KIND-030 by year-end 2021.
