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).

Primary

MeasureTime frameDescription
Maximum Tolerated Dose of N-Acetyl-Cysteine in Ovarian Cancer Patients Receiving Platinum-Based TherapyFrom the start date of treatment until 6 months after removal of treatment due to toxicity, termination of study or withdrawal of treatment, whichever came first.Determination of the maximum tolerated dose (MTD) will be utilized to evaluate the safety and tolerability of adding N-Acetyl-Cysteine (NAC) in ovarian cancer patients who are also receiving platinum-based therapy (PBT), using a Phase I, dose-escalating design.
Recommended Phase 2 Dose for NAC administered with PBTFrom the start date of treatment until 6 months after removal of treatment due to toxicity, termination of study or withdrawal of treatment, whichever came first.Determination of the recommended Phase 2 dose (RP2D) will be utilized to evaluate the safety and tolerability of adding NAC to PBT.
