Pazopanib and Fosbretabulin in recurrent ovarian cancer (PAZOFOS): A multi-centre, phase 1b and open-label, randomised phase 2 trial.
Vascular co-option is a resistance mechanism to anti-angiogenic agents, but combinations of anti-vascular agents may overcome this resistance. We report a phase 1b and randomised phase 2 trial to determine the safety and efficacy of pazopanib with fosbretabulin.. Eligible patients had recurrent, epithelial ovarian cancer with a platinum-free interval (PFI) of 3 to 12 months. Patients were stratified according to PFI (>6 versus ≤6 months) and prior bevacizumab use.. It remains unclear whether pazopanib with with fosbretabulin is an efficacious regimen to treat epithelial ovarian cancer. Effective cardiac risk mitigation is needed to increase the tolerability and maximize patient safety in future trials.

Enhanced biological activity of liposomal methylated resveratrol analog 3'-hydroxy-3,4,5,4'-tetramethoxystilbene (DMU-214) in 3D patient-derived ovarian cancer model.
3'-hydroxy-3,4,5,4'-tetramethoxystilbene (DMU-214) belongs to methoxystilbenes family and is an active metabolite of 3,4,5,4'-tetramethoxystilbene (DMU-212). In several of our previous studies, the anti-apoptotic activity of DMU-214 was significantly higher than that of the parent compound, especially in ovarian cancer cells. Due to increased lipophilicity and limited solubility, methoxystilbenes require a solubilization strategy enabling DMU-214 administration to the aqueous environment. In this study, DMU-214-loaded liposomes were developed for the first time, and its antitumor activity was tested in the ovarian cancer model.First, several liposomal formulations of DMU-214 were obtained by the thin lipid film hydration method followed by extrusion and then characterized. The diameter of the resulting vesicles was in the range of 118.0-155.5 nm, and samples presented monodisperse size distribution. The release of DMU-214 from the studied liposomes was governed by the contribution of two mechanisms, Fickian diffusion and liposome relaxation.Subsequently, Topics: Carcinoma, Ovarian Epithelial; Cell Line, Tumor; Female; Humans; Liposomes; Ovarian Neoplasms; Resveratrol; Stilbenes | 2022 |
Resveratrol inhibits ovarian tumor growth in an in vivo mouse model.
Resveratrol inhibits the growth of ovarian carcinoma cells in vitro through the inhibition of glucose metabolism and the induction of both autophagy and apoptosis. In the current study, we investigated the metabolic and therapeutic effects of resveratrol in vivo.. A fluorescent xenograft mouse model of ovarian cancer was used. Mice were treated with cisplatin, resveratrol, or vehicle alone. Tumor burden was assessed using whole-body imaging. The effect of resveratrol on glucose uptake in vivo was determined using micro-positron emission tomography scanning. To determine whether resveratrol could inhibit tumor regrowth, tumor-bearing mice were treated with cisplatin followed by either daily resveratrol or vehicle. Autophagic response in resected tumors taken from mice treated with resveratrol was examined by transmission electron microscopy. Glycolysis and mitochondrial respiration in ovarian tumor cells after treatment with resveratrol was assessed.. Mice treated with resveratrol and cisplatin were found to have a significantly reduced tumor burden compared with control animals (P<.001). Resveratrol-treated mice demonstrated a marked decrease in tumor uptake of glucose compared with controls. After treatment with cisplatin, "maintenance" resveratrol resulted in the suppression of tumor regrowth compared with mice receiving vehicle alone (P<.01). Tumors resected from mice treated with resveratrol exhibited autophagosomes consistent with the induction of autophagy. Treatment with resveratrol inhibited glycolytic response in ovarian tumor cells with high baseline glycolytic rates.. Treatment with resveratrol inhibits glucose uptake and has a significant antineoplastic effect in a preclinical mouse model of ovarian cancer. Resveratrol treatment suppresses tumor regrowth after therapy with cisplatin, suggesting that this agent has the potential to prolong disease-free survival.
