“These early data are an example of a new direction in development of immunotherapy for platinum-refractory ovarian cancer,” commented Jeffrey S. Weber, M.D., Ph.D.; Deputy Director of the Perlmutter Cancer Center at New York University (NYU)-Langone Health; Co-Director of its Melanoma Research Program Center; and Chair of SELLAS’ Scientific Advisory Board. “In patients who failed as many as five lines of previous therapy, with small numbers of patients, the disease control rate and progression free survival that were observed merit further study. The GPS combination with checkpoint blockade, such as pembrolizumab, should be further explored, both in active disease as well as potentially in the setting of maintenance therapy after patients reach minimal residual disease post salvage therapies,” added Dr. Weber.
