Clinical Trial Launches to Document Efficacy of Animal-Assisted Therapy for Child Cancer Patients and Their Families

Landmark Study Supported by Zoetis and American Humane Association Underway at Five Children’s Hospitals Across the Country

D.C., Feb. 19, 2014– Zoetis Inc. and American Humane Association today announced the official launch of the full clinical trial of the Canines and Childhood Cancer (CCC) Study, a first-of-its-kind effort to examine the effects of animal-assisted therapy on pediatric oncology patients, and their families.

         The CCC Study will examine how animal-assisted therapy affects stress and anxiety among children with cancer and their parents/guardians, as well as health-related quality of life for patients. The study will also examine if and how animal-assisted therapy sessions with this population affect the therapy dogs. The patient population will be children aged 3 through 12 years who are newly diagnosed with childhood cancer and who receive regular chemotherapy treatment in the outpatient clinic.

         Five leading children’s hospitals are participating in the clinical trial – St. Joseph’s Children’s Hospital in Tampa, FL.; Monroe Carrell Jr. Children’s Hospital at Vanderbilt in Nashville, TN; Randall Children’s Hospital at Legacy Emanuel in Portland, OR; UC Davis Children’s Hospital in Sacramento, CA; and UMass Memorial Children's Medical Center in Worcester, MA, in partnership with Cummings School of Veterinary Medicine at Tufts in North Grafton, MA. Each site will collect data for approximately 12 months, with staggered start dates.

         “We strive to advance the understanding and scientific rigor around animal-assisted therapy and to broaden informed adoption of the therapeutic power of the human-animal bond,” said Vanessa Mariani, Director of Academic & Professional Affairs at Zoetis. “These incredible partnerships with participating sites and the collaboration between children’s health providers, patients and veterinarians is a model that we hope to continue advancing in the future for the benefit of children and animals through strong science.”

         While therapy dog programs are common in children’s hospitals across the country, and therapeutic benefits of animal-assisted therapy for patients with cancer have long been shared anecdotally by doctors, patients, families and therapy dog owners, there has been limited hard evidence to substantiate these claims and no rigorous evaluations about how to best implement animal-assisted therapy in pediatric oncology settings. The CCC Study is unique because it will not only measure the well-being effects of animal-assisted therapy on young patients and their families across multiple sites, but also on the therapy dogs themselves.

         “This clinical trial is an important step forward in identifying and understanding perhaps underused weapons in the war on childhood cancer,” said Dr. Robin Ganzert, American Humane Association’s president and CEO. “After years of anecdotal evidence pointing to its effectiveness, we are hoping to examine in a rigorous manner the scientific underpinning of the benefits of animal-assisted therapy on children with cancer.”

         Prior to launching this 12-month clinical trial, the American Humane Association research team and Zoetis published a comprehensive literature review on pediatric oncology and animal-assisted therapy, and conducted a six-month pilot study in early 2013. The literature review and findings from the pilot study can be downloaded from
