Siamab’s ST1 Therapy Candidate Promising Against Chemoresistant Ovarian Cancer, Study Shows
Siamab Therapeutics' investigational antibody-drug conjugate ST1 has promising anti-tumor effects against chemotherapy-resistant ovarian cancer in cell and animal models, a study shows.  The study, “Treatment of ovarian cancer by targeting the tumor stem cell-associated carbohydrate antigen, Sialyl-Thomsen-nouveau,” was published in the journal Oncotarget. Tumor chemoresistance and recurrence is a serious health-threatening issue, affecting most women with ovarian cancer. New treatment strategies are urgently needed to target chemoresistant disease that does not respond to current therapies. Recurrent ovarian cancer is thought to occur because the body fails to eliminate rare cancer stem cells that are able to survive chemotherapy and lead to tumor relapse. Cancer stem cells are not unique to ovarian cancer and have been found in many other tumors. Given their key role in cancer progression, they have been pinpointed as important therapeutic targets. Researchers have been investigating molecules express
