Brief Summary

This is a phase I, dose-escalation and phase II dose-expansion clinical trial determining the maximum tolerated dose (MTD) and safety and tolerability of adding N-Acetyl-Cysteine (NAC) to ovarian cancer patients who are receiving a platinum-based therapy (PBT). This study will investigate whether NAC will mitigate chemotherapy-related cognitive impairment (CRCI).
