Researchers at the University of Pennsylvania School of Veterinary Medicine are evaluating a new vaccine for dogs that have been diagnosed with osteosarcoma. Osteosarcoma (bone cancer) is most commonly seen in large and giant breeds of dogs. It is an aggressive cancer that frequently affects the long bones. Despite limb amputation and chemotherapy, many dogs die from the cancer that spreads to their lungs. Details of the study, including the benefits of enrollment, are available here
Mason Bone Cancer Study: Evaluation of a recombinant bacteria vaccine to treat bone cancer in dogs
Purpose
The purpose of this study is to determine whether a recombinant L. moncytogenes vaccine can elicit anti-tumor immunity and prolong survival in dogs with cancer of their long bones (appendicular osteosarcoma (OSA)).
If your dog has recently been diagnosed with bone cancer, or is currently undergoing
chemotherapy for bone cancer, he/she may be eligible for vaccination.
Enrollment criteria and baseline evaluation of patients
Researchers are actively recruiting patients for a pilot study to determine the safety and efficacy of a new bacteria based vaccine to stimulate an immune response against osteosarcoma and prolong survival in dogs with bone cancer. Only those dogs with a histological diagnosis of osteosarcoma and who have undergone limb amputation and standard chemotherapy (4 doses of carboplatin) for the treatment of osteosarcoma will be eligible for inclusion in the study. In addition, only those patients whose tumors express the target antigen “Her-2/neu” will be eligible for inclusion in this study.
Up to 18 privately owned dogs with long bone cancer (appendicular OSA) and confirmed expression of Her2-neu will be enrolled.
