Immunotherapy Clinical Trial for Dogs with Solid Tumors

Feb 1, 2021

This purpose of this pilot study is to evaluate the safety and activity of a STING agonist compound to stimulate the immune system to attack cancer cells in dogs with malignant melanoma, mammary carcinoma, squamous cell carcinoma on the head or neck, and high grade soft tissue sarcoma. Other solid tumors may qualify as well. 


In order to be eligible dogs must:

  • Weigh 33 lbs or more
  • Have a diagnosis of a solid, malignant tumor type such as:
    • Malignant melanoma
    • Mammary carcinoma
    • Squamous Cell Carcinoma of the head or neck
    • High grade soft tissue sarcoma
    • Osteosarcoma (if amenable to repeat biopsy)

Prior treatment is permitted as long as there is a measurable tumor present. Anticipated study duration is 6 weeks. The trial includes an initial staging appointment, two immunotherapy treatments requiring overnight stays in the hospital, and surgery. All appointments require the ability to travel to Ryan Veterinary Hospital in Philadelphia, PA and adherence to the study schedule. 


All study specific visits, including staging and surgery, covered by the study.
