Tinzaparin And Biomarkers After Neoadjuvant Treatment of Ovarian Cancer

Launched by UNIVERSITY HOSPITAL, LINKOEPING · Mar 8, 2022

ClinConnect Summary

This clinical trial is studying the effects of a medication called tinzaparin, which is typically used to prevent blood clots, in women with advanced epithelial ovarian cancer who are receiving chemotherapy before surgery. Researchers want to see if tinzaparin can help lower levels of a specific cancer marker called CA-125 and how it affects the immune system and blood clotting factors in these patients.

To participate in the trial, women must be 18 or older, diagnosed with certain types of ovarian or related cancers, and be planning to receive a specific type of chemotherapy. Participants will receive tinzaparin injections and will be monitored for any side effects. The trial is currently recruiting participants, so if you think you might be eligible, it’s a good idea to discuss this with your doctor for more information.
