"Canine Cancer: Take C.H.A.R.G.E." (Canine Health And ReGistry Exchange) Based on Nationwide Gallup Poll of Pet Owners and Initial Assessment of More Than 35,000 Canine Medical Records

Initial Data from Gallup Poll of More Than 3,500 Dog Owners Suggest Nearly Five-Fold Greater Incidence of Canine Cancer Than Human Cancer; More Than 80 Percent of Respondents Believe a Registry is Needed to Help Dogs with Cancer

Take C.H.A.R.G.E. Scientific Advisory Board of Veterinary Oncologists and Experts Support Adoption of New Comparative Oncology Diagnostic Codes to Strengthen Registry Impact

Join us TODAY for Special NYC Media Event and Performance to Celebrate the Launch of Take C.H.A.R.G.E. on National Canine Cancer Awareness Day

SAN FRANCISCO, CA / ACCESSWIRE / May 23, 2022 / Jaguar Health, Inc. (NASDAQ:JAGX) today announced the launch of Canine Cancer: Take C.H.A.R.G.E. (Canine Health And ReGistry Exchange), a first-of-its-kind national Canine Cancer Registry and Canine Cancer Care Index to provide the veterinary community and dog owners with important incidence and prevalence data to help guide canine cancer diagnosis and treatment decisions. Launched on the first National Canine Cancer Awareness Day and co-sponsored by Jaguar Animal Health, TogoRun, and Ivee, the initiative will initially access information about canine cancer from two key sources: a nationally representative multi-year Gallup survey of U.S. dog owners, and a retrospective review of more than 35,000 anonymous canine patient records uploaded into a secure customized database with more than 830 confirmed cancer diagnoses.

The Gallup survey, conducted in March 2022, estimated the prevalence - the percent of U.S. dogs with cancer in 2021 - was 3.4 percent, less than the approximately 5 percent prevalence in humans that year. The survey also found that the incidence - the percent of U.S. dogs newly diagnosed with cancer in 2021 - was 2.8 percent, which is approximately five times the 0.57 percent incidence of newly diagnosed cancer in humans that year. This finding is startling since researchers have assumed that canine cancer rates mirror human cancer rates.

"We established Take C.H.A.R.G.E. to fill a major research gap among the veterinary community and dog owners in the United States because, until now, there has been no nationally based dog owner survey or registry focused on canine cancer," said Jaguar Health founder, president and CEO Lisa Conte. "The information from Take C.H.A.R.G.E. will provide the first ever national representation of the incidence and prevalence of canine cancer and will help inform decisions that advance the quality of life of both dogs with cancer and their owners. The data may also provide insights to help better understand cancer in humans."

Other key findings from the Gallup survey include:

• More than 8 in 10 dog owners favored the creation of a canine cancer registry to better understand the disease and advance treatments
• After mixed-breed dogs, the 10 most represented breeds in the survey were: 1) Labrador, 2) Chihuahua, 3) Pitbull, 4) Golden Retriever, 5) German Shepherd, 6) Yorkshire, 7) Dachshund, 8) Boxer, 9) Beagle, and 10) Shih Tzu
• 68 percent decided not to treat their dog for cancer due to the age of their dog (54 percent), treatment cost (39 percent), treatment side effects (38 percent), or other reasons
• Across all dog owners, the vast majority (92 percent) said they did not have pet insurance at the time of diagnosis
• Nearly 3 in 4 dog parents who experienced canine cancer in the past 10 years were satisfied or very satisfied with their overall experience during treatment, even though only 39 percent reported that their dog was actually cured or went into remission
• While a high proportion of dog owners (46 percent) ‘strongly agreed' that their dog received high quality cancer care, only 30 percent strongly agreed that they knew what to expect during their dog's cancer treatment
• When asked to imagine how difficult it would be for members of their household to manage various chemotherapy-related side effects, the percent of all dog owners rating them as difficult or very difficult were: pain (60 percent), urinary incontinence (43 percent), diarrhea (41 percent), vomiting/nausea (39 percent), decreased appetite (20 percent), and fatigue/lethargy/lack of energy (19 percent)
• Dealing with canine cancer has a major impact on dog owners' well-being, including depression, anxiety, lack of sleep, and missing work or other obligations; for example, 63 percent of respondents reported feeling a lot of stress and 58 percent reported feeling down and depressed a lot during their dog's cancer
• Dog owners' ability to manage their dog's side effects from cancer treatment, such as pain, urinary incontinence, and diarrhea, is the best predictor of key well-being outcomes of the pet owner
• However, many dog parents find managing treatment side effects especially challenging:
  • 92 percent of dog owners with no canine cancer experience and 65 percent of those with canine cancer experience said they knew little or nothing about side effects
  • Only 22 percent ‘strongly agreed' that they have been able to manage their dog's cancer treatment side effects well, and only 29 percent have a clear understanding of potential side effects of treatment
• Having a veterinarian who cares about a dog's comfort, high quality of care, and thorough explanation of treatment options were most critical to overall treatment satisfaction, whereas management of side effects was the most important factor in determining the negative impact canine cancer has on dog parents' well-being

Canine Cancer Care Index

In addition to assessing canine cancer incidence and prevalence, and dog owners' perceptions, emotions and experiences related to canine cancer, Gallup used data from the survey to calculate a Canine Cancer Care Index that reflects three dimensions related to canine cancer care: knowledge, quality of care, and canine comfort. Ranging from 0 (the worst possible score) to 100 (the best possible score), the Index will help assess whether canine cancer care experiences are improving, worsening, or staying the same for dog owners and their dogs over time. Gallup determined that the baseline for the Canine Cancer Care Index is 80.5 or a B-, indicating a clear need for improvement.

"Protecting dogs from cancer begins with knowing its impact by breed, type, age, gender, and location," said Take C.H.A.R.G.E. Scientific Advisory Board co-chair Dr. Terry Fossum, DVM, MS, PhD, Diplomate ACVS. "The U.S. has lagged behind other countries where there are multiple canine health registries and there have been several attempts by other groups to establish a U.S. registry without success. We have to do better for our dogs and we believe Take C.H.A.R.G.E. finally will give us the tools we need to advance canine cancer care."

Take C.H.A.R.G.E. Scientific Advisory Board

The Take C.H.A.R.G.E. Scientific Advisory Board (SAB) includes eight leading U.S. veterinarians specializing in canine oncology and surgery. One of the SAB's first and most important activities is driving adoption of a consistent canine cancer diagnostic coding system and supporting the goals of the National Institutes of Health/National Cancer Institute Comparative Oncology Program.¹ Comparative oncology is the study of naturally developing cancers in pet dogs and other animals as models for human cancers. It provides a novel approach to generate new information about cancer, for example environmental risk factors, genetic determinants, and evaluation of new treatment approaches. In support of comparative oncology, the SAB is encouraging veterinary clinics to adopt coding practices that align with the recently published Veterinary International Classification of Diseases for Oncology Canine Tumors First Edition, or Vet-ICD-O-canine-1,² which is based largely on the most recent version of the human cancer coding system, ICD-O-3.2.³

"The heart of any cancer registry is its cancer coding system," said SAB co-chair Dr. Craig Clifford, DVM, MS, DACVIM (Oncology). "As we continue to enhance the Take C.H.A.R.G.E. registry, we will incorporate Vet-ICD-O-canine-1, as it is a user-friendly, easily accessible, comprehensive resource for veterinary doctors, researchers, and specialists. This will allow us to make more ‘apples to apples' comparisons of canine cancers in the United States and other countries and regions, which in turn will help us better understand and treat canine cancer."

The Take C.H.A.R.G.E. SAB members include:

• Dr. Craig Clifford, DVM, MS, DACVIM (Oncology), SAB Co-chair. Director of Blue Pearl Science and Medical Oncologist at BluePearl Pet Hospital in Malvern, PA.
