An experimental vaccine against breast cancer safely generated a strong immune response to a key tumor protein, researchers from the University of Washington (UW) School of Medicine in Seattle report in a paper published by the journal JAMA Oncology. The findings suggest the vaccine may be able to treat different types of breast cancer.

“Because this was not a randomized clinical trial, the results should be considered preliminary, but the findings are promising enough that the vaccine will now be evaluated in a larger, randomized clinical trial,” said lead author Dr. Mary “Nora” L. Disis, a UW professor of medicine, Division of Medical Oncology, and director of the Cancer Vaccine Institute.

Two patients with advanced Hodgkin lymphoma were told their tumors were
so resistant to treatment that hospice was their best option. Then, they were
enrolled in a clinical trial of a novel immunotherapy involving so-called
natural killer cells. After treatment, they saw complete remission.
Researchers say the results are a hopeful if preliminary sign of the potential of immunotherapies harnessing natural killer, or NK, cells — innate immune system cells that have certain advantages over the more commonly recognized adaptive T cell cancer therapies.
The treatment in the study, developed by the University of Texas MD Anderson Cancer Center and the German drug maker Affimed, combined offthe-shelf NK cells with a separate antibody that primes the cells to recognize a specific protein signature of the tumors. Two additional patients administered
the same treatment have shown ongoing partial responses.
“These results show you just how powerful NK cells are,” said Katy Rezvani,
a stem-cell transplant physician and NK cell researcher at MD Anderson, who
is spearheading the development of this new treatment.
“It’s amazing when you see these responses for patients who have so few
options, patients who’ve been told that they should go to hospice,” Rezvani
said.“I cannot begin to tell you how satisfying this is for clinicians.”
Data from the study is to be presented at the annual meeting of the American
Association for Cancer Research (AACR).
