Clinical trial for dogs with externally accessible malignant tumor

Evaluation of locally-delivered nanotherapy cisplatin in combination with radiation therapy in dogs with any malignant tumor.

Purpose and Brief Study Description:

This trial evaluates the administration and clinical response to a new conjugate of cisplatin chemotherapy, administered in combination with palliative radiation therapy, in dogs with any naturally-occurring, externally-measurable, malignant tumor, which is not amenable to surgical resection for whatever reason.

Cisplatin is considered one of the most potent and broad spectrum chemotherapeutic agents; however, is associated with significant side effects. This reformulation of cisplatin into a nanoparticle conjugate has shown promise as a safer, less toxic and efficacious alternative.

Enrollment Criteria:

  • Dogs with any cytologically- and/or histologically- confirmed, externally-measurable malignant tumor, not amenable to surgical resection for whatever reason, that are good candidates for radiation therapy would be considered for enrollment.
  • Dogs of any breed, age, gender and weighing a minimum of 10.0kg (22lbs), with a satisfactory health score.
  • Complete staging/re-staging would be required prior to study enrollment, including blood work (CBC and chemistry), urinalysis, thoracic radiographs or computed tomography of the thorax, and/or abdominal ultrasound or computed tomography of the abdomen.
  • Prior surgery, chemotherapy (excluding a platinum agent), corticosteroids, NSAIDs, and/or radiation therapy is allowable if reoccurrence or progression is documented at the time of study enrollment with minimum washout periods of one month for radiation therapy, three weeks for chemotherapy, and 72 hours for NSAIDs and/or corticosteroid therapy. Concurrent chemotherapy, corticosteroids and/or radiation therapy are not allowable.

What does enrollment into this trial involve?

All enrolled dogs will receive the cisplatin conjugate subcutaneously to the primary tumor on study days 0, 7, 14, and 21, at incrementally increasing doses. Within 4 hours of cisplatin conjugate administration, enrolled dogs will also concurrently receive one fraction of radiation therapy to the tumor site (for a total of 4 factions). Blood samples will be collected immediately prior to each dose of chemotherapy, and also weekly for three weeks following the final dose. After study day 42 (or sooner if your dog is removed from the study), the study will be completed and the oncology clinician will discuss additional treatment options with you.

Client Compensation:

This study will cover the costs of recheck visits up to and including study day 42. This includes physical exam, bloodwork, and urinalysis, as well as the costs of 4 doses of cisplatin conjugate and 4 fractions of radiation therapy. The owner is responsible for the costs associated with staging prior to enrollment, including the initial oncology consultation, chest x-rays, abdominal ultrasound, and computed tomography (CT) imaging.
