Evidence Level:Sensitive: C3 – Early Trials
New
Title:
Correlation of cyclin E1 expression and clinical outcomes in a phase 1b dose-escalation study of azenosertib (ZN-c3), a WEE1 inhibitor, in combination with chemotherapy (CT) in patients (pts) with platinum-resistant or refractory (R/R) epithelial ovarian, peritoneal, or fallopian tube cancer (EOC).
Excerpt:Azenosertib + CT is well tolerated and has encouraging clinical activity, with durable responses in pts with platinum R/R EOC. Pts with Cyclin E1 overexpressing tumors, a subgroup with suboptimal benefits from CT, demonstrated significant improvements in ORR and PFS vs pts with tumors having low expression.
Secondary therapy:carboplatin; doxorubicin hydrochloride; gemcitabine; paclitaxel

Title:
2153 / 27 - Cyclin E1 protein overexpression sensitizes ovarian cancer cells to ZN-c3, a novel, selective and oral bioavailable inhibitor of Wee1
Excerpt:Ovarian cancer cell lines overexpressing Cyclin E1 protein (Cyclin E1high) were more sensitive to azenosertib than ovarian cancer cell lines with lower levels of Cyclin E1 protein (Cyclin E1low) inducing significant cytotoxic effects (GRmax < -0.5)…. In vivo, the synergy between azenosertib and paclitaxel was stronger in Cyclin E1high OVCAR3 model (46% reduction of initial tumor volume/104% TGI) than Cyclin E1low A2780 model (85% TGI).
