Immune checkpoint inhibitor therapy has proven effective against many types of solid tumors, but not many subtypes of ovarian cancer, including the rare subtype of ovarian clear cell carcinoma (OCCC). Now, researchers have identified a subtype of OCCC that involves inactivating mutations in the gene PPP2R1A and that responds well to immune checkpoint inhibitor therapy.
The sodium-dependent phosphate transport protein 2b (NaPi2b), encoded by the SLC34A2 gene, is highly overexpressed in high-grade epithelial ovarian cancer and non-small-cell lung cancer while exhibiting minimal expression in normal adult tissues, making it a relevant tumor-associated antigen and a promising target for antibody-drug conjugates (ADCs).
Cancer cells often use epigenetic changes to resist treatment, a major factor particularly in late-stage deaths from ovarian cancer. One potential epigenetic marker, DNA secondary structures known as G-quadruplexes (G4s), has recently gained attention; however, their presence and role in ovarian cancer had not been studied until now.
China’s National Medical Products Administration gave the green light to Simcere Pharmaceutical Group Ltd.’s Enzeshu (suvemcitug) for treating recurrent ovarian cancer, fallopian tube cancer, or primary peritoneal cancer in combination with paclitaxel, liposomal doxorubicin, or topotecan in adults who have received at least one systemic therapy after platinum resistance.

Researchers from the University of Oslo and Oncoinvent ASA present a new PTK7-targeted α therapy using a lead-212 (212Pb)-labeled antibody, potentially offering a novel approach for treating PTK7-expressing malignancies, and its assessment in a preclinical study.
Mayo Foundation for Medical Education and Research (MFMER) has described glycogen synthase kinase 3 (GSK-3) inhibitors reported to be useful for the treatment of cancer, neurological and psychiatric disorders.
Sunshine Lake Pharma Co. Ltd. has disclosed Myt1 kinase (PKMYT1) inhibitors reported to be useful for the treatment of cancer, psoriasis and rheumatoid arthritis.
Blueprint Medicines Corp. has identified proteolysis targeting chimera (PROTAC) compounds comprising an E3 ubiquitin ligase-binding moiety covalently linked to a cyclin dependent kinase 2 (CDK2)-targeting moiety through a linker reported to be useful for the treatment of cancer.
Researchers at Queen’s University of Belfast and collaborators have developed a DNA vaccine against high-grade serous ovarian cancer. The vaccine encodes PRAME, which the researchers found to be upregulated in several cohorts of patients with the malignancy.
