The study is being done to research if hydroxychloroquine can prevent chemotherapy induced
peripheral neuropathy. Certain chemotherapy drugs, like paclitaxel, are known to cause
neuropathy which can impact quality of life. Currently, there are no options for preventing
peripheral neuropathy. In addition, there are no useful methods to assess peripheral nerve
damage. This study will also explore using a study MRI of patients' feet prior to starting
chemotherapy and after they have completed chemotherapy to see if there is any difference in
their nerve structure.
