Several Phase 3 trials are addressing important questions in ovarian cancer management. One is comparing one versus two years of olaparib with or without bevacizumab as maintenance therapy after frontline treatment, examining whether longer PARP inhibitorDrugs that block PARP enzymes, exploiting DNA repair defects in cancer cells such as those with BRCA mutations.Click for full explanation → duration extends benefit. Another Phase 3 study is evaluating sacituzumab tirumotecan, a TROP2-targeting ADC, in patients with non-HRD positive advanced ovarian cancer. A Phase 3 trial is testing pembrolizumab combined with paclitaxel with or without bevacizumab for platinum-resistant recurrent disease.
Novel cell therapies are being explored. A Phase 1 trial is evaluating dual-targeting CAR-NK (chimeric antigen receptorA type of immunotherapy that genetically engineers a patient's own T cells to recognise and destroy cancer cells.Click for full explanation → natural killer) cells against mesothelin, FR-alpha, and MUC16. A Phase 2 trial is studying gemcitabine with or without the WEE1 inhibitor adavosertib in recurrent disease, targeting a DNA damage response pathway.
Research from recent literature identifies NRF2 (nuclear factor erythroid 2-related factor 2) as a driver of chemoresistance in ovarian cancer stem-like cells and describes platelet-induced VISTA expression as a mechanism of immune modulation in the tumor microenvironment, providing potential new targets.

CRB2 Protein Linked to Ovarian Cancer Progression
Researchers studied the role of CRB2 protein in ovarian cancer and found that it may contribute to the disease's progression. They discovered that CRB2 is overexpressed in ovarian cancer tissues and is associated with poor patient outcomes. In lab experiments, CRB2 enhanced cancer cell growth and spread.

New Lab Model Reveals How Cancer Cells Influence Surrounding Cells
Researchers created a 3D lab model that includes five types of human cells to study how cancer cells affect the cells around them. They found that cancer cells can influence the behavior of immune cells called macrophages. The study suggests that the behavior of these immune cells can vary depending on the type of cancer cell.
