ClinConnect Summary

This clinical trial is investigating the effects of a new treatment called oregovomab in combination with standard chemotherapy for women who have recently been diagnosed with advanced ovarian cancer. The goal is to see if adding oregovomab helps improve treatment outcomes compared to chemotherapy alone. Participants will receive five doses of oregovomab along with a standard chemotherapy regimen that includes two medications: paclitaxel and carboplatin. This study is designed for adult women aged 18 and older who have a specific type of ovarian cancer that has been confirmed by a biopsy.

To participate, women need to meet certain health criteria, such as having a confirmed diagnosis of advanced ovarian cancer and having adequate blood and organ function. They should not have received any previous cancer treatments and must be willing to avoid pregnancy during the study. If eligible, participants can expect regular visits for treatment and monitoring, and they will contribute to important research that may improve future therapies for ovarian cancer. It's important to note that this trial is currently recruiting participants, so women interested in joining should speak with their healthcare provider for more information.
