Glutathione in Preventing Peripheral Neuropathy Caused by Paclitaxel and Carboplatin in Patients With Ovarian Cancer, Fallopian Tube Cancer, and/or Primary Peritoneal Cancer


About this study

This randomized phase III trial is studying glutathione to see how well it works in preventing peripheral neuropathy caused by paclitaxel and carboplatin in patients with ovarian cancer, fallopian tube cancer, and/or primary peritoneal cancer. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Chemoprotective drugs, such as glutathione, may help prevent peripheral neuropathy caused by paclitaxel and carboplatin. It is not yet known whether glutathione is more effective than a placebo in preventing peripheral neuropathy.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.


Inclusion Criteria:

Scheduled to undergo treatment with TAXOL at 150-200 mg/m2 and CBDCA at area under the curve (AUC) = 5-7 every 21 or 28 days for at least 12 weeks; alternatively, paclitaxel can be prescribed at 80 mg/m2 weekly for at least 12 weeks, with the same CBDCA dose of AUC = 5-7 every 21 days; additional chemotherapy agents are allowed (bevacizumab, etoposide, etc) per physician discretion, as long as they are not known to be neurotoxic; Note: patients ideally will begin GSH therapy prior to their first dose of this chemotherapy, but must begin GSH therapy prior to their second dose of chemotherapy
