Gold Nanoparticles

We are conducting a trial for utilizing gold nanoparticles paired with infrared laser heat. Eligible patients have to have superficial tumors. We are treating the following types:

• Dogs with large mast cell tumors (>2 cm)

• Dogs with soft tissue sarcomas (<2cm in diameter)

• Dogs with oral melanoma (2-3cm diameter)

• Dogs with cutaneous or footpad melanoma (<2cm)

• Cats with oral squamous cell carcinoma not involving the bone.

This new clinical trial utilizes gold nanoparticles in a gross disease setting.

Gold Nanoparticles are inert and are given IV to the patient and after a period of time the patient comes back to have the tumor heated with a laser. As the tumor vasculature is heated through the external near infrared spectrum of light, the gold nanoparticles are excited, the laser energy is converted to heat and the tumor vasculature is disrupted killing the tumor from the inside out.

Smaller tumors typically need only the 1 session of heat but larger tumors may need more than 1 session of heat (average 2-3 for sarcomas).

THE TRIAL IS NOW ENROLLING PATIENTS!

If you have a potential case to discuss, have a patient with a tumor in a bad location for surgery or if you would like to learn more, please contact us at 425-697-2272 for more information.

 Paclitaxel for Hemangiosarcoma

BARC is enrolling patients in a clinical trial for a unique chemotherapy agent for splenic hemangiosarcoma patients. Paclitaxel is the drug of choice in humans with angiosarcoma and needs to be re-evaluated in dogs. Paclitaxel has historically not been well tolerated in dogs in its original formulation. This new formulation hopes to mitigate those side effects and have efficacy in this disease.

We are enrolling pet companion dogs that have been diagnosed with non-metastatic histopathologic diagnosed splenic hemangiosarcoma.

These patients will receive further staging to verify no visible metastasis are present at the time of enrollment. The drug will be given IV every 3 weeks for a total of 5 doses. Patients are allowed to be on Yunnan Baiyao but no other immunotherapies, supplements or chemotherapy.

This trial is fully funded and staging and chemotherapy visits are covered by the sponsor.

Please have your veterinarian call or email us if your patient may be a candidate for this trial as we do want to prioritize referral for these patients.

 Immunotherapy for Transitional Cell Carcinoma of Urothelial Carcinoma

This study seeks to evaluate a novel immunotherapy when used in dogs with transitional cell (TCC) or urothelial carcinoma (UC). The therapy specifically targets an important molecule primarily expressed on immune cells, which usually turns off the immune cells and prevents overactive immune responses. However, it also turns off anti-cancer immune responses and prevents the immune system controlling and killing cancer cells.

Immunotherapies that are able to inhibit this molecule on immune cells that recognize cancer cells could make it possible for the immune system to recognize and attack the underlying cancer more effectively.

Your Dog may be eligible if:

• Weigh ≥ 5kg and ≤ 35kg

• Histologically conrmed transitional cell or urothelial carcinoma, with or without documented lymph node involvement (newly diagnosed dogs and recurrent/relapsed disease)

• Measurable primary intravesicular tumor amenable for cystoscopic biopsy

• No signicant comorbidities

• Expected survival time of at least 8 weeks

• Dogs receiving standard of care NSAID for UC for at least 2 weeks prior to study enrollment will be allowed to continue SOC while on study

• Dogs can be on Heartworm preventative during the study

Your Dog is NOT eligible if:

• History of daily drug administration for an unregulated chronic disease (i.e. still dose adjusting at this time)

• Prior experimental therapy, antibody therapies, immunomodulatory therapies (Prednisone, Cyclosporine, Atopica, MMF or other therapies) within six weeks of study

• Other chemo/radiation therapy within two weeks of study

• Pulmonary metastasis

• Symptomatic urinary tract infection confirmed by urine culture

• Creatinine >2.0 mg/dL ; Total bilirubin >2.0mg/dL ; HCT <25% or platelets <50,000

• Any grade II hematologic or biochemical abnormality by VCOG standards

• Prior antibody therapies (Cytopoint or Librela)

• No vaccines within the study period (can happen >2 weeks before enrollment)

CLIENT INCENTIVE: Fully funded. All treatments and procedures will occur with no cost to the owner.

EGFR Immunotherapy available

BARC is now offering a unique immunotherapy that targets the EGFR/HER2 pathway. Epidermal Growth Factor Receptor (EGFR) is overexpressed on a number of human cancers, and often is indicative of a poor outcome.

We are hoping to induce a polyclonal anti-EGFR/HER2 tumor antigen response by vaccine therapy.

We are enrolling companion dogs with spontaneous EGFR expressing tumors to receive a series of 2 vaccines 3 weeks apart. There is annother visit after vaccination to draw a blood sample for antigen response analysis. Dogs with EGFR expressing tumors will be immunized with a short peptide of the EGFR extracellular domain with sequence homology to HER2.

To receive the immunotherapy without required Oncologist consultation:

1. Referral direct from another Veterinary Oncologist

2. Viable tumor types include:

• Osteosarcoma patients

• Hemangiosarcoma patients

• Transitional Cell Carcinoma

• Pulmonary Carcinoma (with records review)

• High grade Mast cell tumors (with records review)

Naive patients can also schedule to have an Oncology consult and this therapy will be discussed if applicable to your dogs disease profile.
