The 112-patient study showed those treated with IMNN-001 plus chemotherapy had a median overall survival length of 46 months compared to 33 months for those treated with standard of care, the company said.

Imunon said it recently initiated the first two sites for a phase 3 study of the drug in newly diagnosed advanced ovarian cancer.
