Effective therapeutics for ovarian cancer continue to be urgently needed,
particularly for chemotherapy-resistant cases. Here we present both a 3D-Matrigel
culture-based expansion of our directed evolution method for generation of
oncolytic virotherapies and two promising ovarian-cancer targeted oncolytic
viruses, OvAd1 and OvAd2. OvAd1 was developed using Matrigel cell cultures,
whereas OvAd2 was developed in parallel using traditional monolayer tissue
culture methods. Both viruses are potent against a panel of platinum-resistant
ovarian cancer cell lines and are attenuated on normal cells in vitro, resulting
in therapeutic windows of ?200-fold. We observed two benefits of the use of
Matrigel-based cultures for directed evolution of these oncolytics: (1) use of
Matrigel generated a bioselected pool that was more strongly attenuated on normal
cells while retaining its potency against ovarian cancer cells, and (2) in an
ovarian carcinomatosis model, the Matrigel-derived virus OvAd1 suppressed all
tumor growth while the non-Matrigel-derived virus was 50% effective. Neither
virus stimulated formation of peritoneal adhesions as seen for Ad5-based
therapies. Consequently, these viruses are novel candidates for development as
new effective treatments for aggressive ovarian cancer.
