Diarrhea is also a prevalent side effect in dogs undergoing cancer treatment; managing diarrhea can be important to maintain successful cancer treatment in both humans and dogs

SAN FRANCISCO, CA / ACCESSWIRE / June 13, 2022 / Jaguar Health, Inc. (NASDAQ:JAGX) today announced that an article by Dr. Kathleen Kiernan Harnden titled Alleviating Targeted Therapy Side Effects: Essential for Patient QOL and Best Outcomes was published June 8, 2022 in Onco'Zine.

Highlights from the article:

• As many as 50% to 100% of cancer patients experience diarrhea, depending on their treatment regimen.
• Diarrhea can severely impact quality of life, including the ability to function well at work, care for children, travel, participate in outdoor activities and achieve good quality sleep.
• Even mild diarrhea over days and weeks can lead to weight loss, clinical deterioration, and mental stress. At its worse, it is a debilitating and potentially life-threatening toxicity that can cause dehydration, electrolyte imbalances, renal insufficiency, malnutrition and extreme dehydration, all of which can lead to cardiovascular compromise and death.
• As the use of targeted therapies increases, so too does the need to better control side effects like diarrhea.
• Regardless of the individual circumstances while on treatment, it is imperative to control difficult side effects so patients can remain on treatment and have the best chance of fighting their cancer.
• Limited options are available for controlling diarrhea. Antidiarrheal use is challenging because patients typically use them after experiencing one or more diarrhea episodes. The available medications also cause constipation.

"Management of cancer treatment-related side effects such as diarrhea is critical in patients - whether the patient is a human or a dog," said Lisa Conte, Jaguar's President, CEO and Founder. "Studies have found the incidence of chemotherapy-induced diarrhea (CID) to be one of the three most prevalent side effects in dogs undergoing cancer treatment, and managing side effects such as CID can be important to maintain successful cancer treatment. The results of a Gallup survey of dog owners, conducted as part of the recently launched Jaguar Health Canine Cancer: Take C.H.A.R.G.E. (Canine Health And ReGistry Exchange) initiative, make it clear that the side effect of diarrhea is a significant concern among owners of dogs diagnosed with cancer. Of respondents who indicated that they decided not to treat their dog's cancer, 38 percent indicated that their decision was due to concern about treatment side effects."

Jaguar's crofelemer drug product candidate is the subject of the OnTarget study, an ongoing pivotal Phase 3 clinical trial for prophylaxis of diarrhea in adult cancer patients receiving targeted therapy.

The company's Canalevia^®-CA1 prescription drug product for the treatment of chemotherapy-induced diarrhea (CID) in dogs received conditional approval from the FDA on December 21, 2021 and is now available from multiple leading veterinary distributors in the U.S.

Onco'Zine, a publication of The International Oncology Network, was created to inform, educate, and support physicians and healthcare professionals treating cancer patients. Kathleen Kiernan Harnden, MD MBA, is the Director of the Breast Medical Oncology Program at Inova Schar Cancer Institute in Fairfax, Virginia.
