Clinical Trials For Cancer Vaccine
To Be Tested On Dogs

The Flint Animal Cancer Center of the James L. Voss Veterinary Teaching Hospital is looking to enroll 800 healthy, middle-aged pet dogs to help develop an all-new cancer vaccine that could potentially be used in humans.

According to the research website, the goal of the VACCS trial is to evaluate a new vaccine strategy for the prevention, rather than treatment of dogs with cancer.

The vaccine is initially the idea of a scientist, inventor, and director of Arizona State University’s Center for Innovations in Medicine, Stephen Johnson and his team. Johnston wanted the trial to be conducted in humans — but the costs and tedious procedure of acquiring certification held him back.

Before the trial, Johnston was introduced to Dr. Douglas Thamm, the current director of clinical research at the Colorado State University’s Flint Animal Cancer Center. Thamm enlightened Johnson that the vaccine could be tested on animals, specifically dogs.

“The kinds of cancers humans and dogs get are very similar. The kinds of cancer that they get occur in the same environment that humans get cancer with. So, we breathe the same air, our lawns are sprayed with the same chemicals. Dogs are the perfect intermediate model in this specific situation,” Thamm says in an interview.

The clinical trials for the cancer vaccine will be conducted at Colorado State University (CSU), a leader in animal cancer research and treatment. Furthermore, the vaccine will act as a preventive measure against cancers of all kinds.

“As one of the top animal cancer centers in the world, CSU and our team are in an excellent position to lead this new clinical trial,” Thamm said. “We look forward to contributing to this groundbreaking research study.”

In particular, Thamm gave the idea that the vaccine can also be tested on dogs. Johnston and his team found a way to identify commonalities among cancerous tumors by screening 800 dogs who had at least one of the eight cancers most often found in canines. Using that information, Johnston created a potential one-size-fits-all vaccine that can help the canine’s immune system to prepare, anticipate, and attack any possible cancer threats.

“We anticipate if we vaccinate with these 31 components ahead of time, just like an infectious disease vaccine, the dog’s immune system will be prepared — pre-prepared to see a tumor and kill it,” Johnston says.

The new vaccine, called a multivalent frameshift peptide vaccine, was also found useful in mice and has shown to be safe for use in companion animals, the CSU’s College of Veterinary Medicine and Biomedical Sciences (CVMBS) said.
