You are being asked to take part in this research study because you are going to be treated with oxaliplatin chemotherapy as part of your standard care. Oxaliplatin commonly causes neuropathy (numbing, tingling and/or pain).The purpose of this study is to compare the effects, good and/or bad, of venlafaxine with a placebo (an inactive agent) on oxaliplatin-induced neuropathy (numbing, tingling and/or pain)

Clinical Details

Official title: A Pilot Randomized, Placebo-controlled, Double Blind Study of Venlafaxine to Prevent Oxaliplatin-Induced Neuropathy

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Supportive Care

Primary outcome: Chronic, cumulative neurotoxicity associated with oxaliplatin during the treatment course as measured by the sensory subscale of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-CIPN20

Secondary outcome: Acute neuropathy associated with oxaliplatin as measured by EORTC QLQ CIPN20 motor subscale (items 37, 38, 41-45 and 49), and autonomic scale (items 46, 47, 50), CTCAE neuropathy scale, oxaliplatin-specific scale, and oxaliplatin symptom questionnaires

Detailed description: PRIMARY OBJECTIVES: I. To explore whether venlafaxine can prevent or ameliorate chronic, cumulative neurotoxicity associated with oxaliplatin in cancer patients receiving oxaliplatin, fluorouracil, leucovorin calcium (FOLFOX). SECONDARY OBJECTIVES: I. To explore whether venlafaxine can ameliorate acute neuropathy associated with oxaliplatin. TERTIARY OBJECTIVES: I. To explore whether venlafaxine can increase the cumulative oxaliplatin doses that can be delivered without dose-limiting chronic neurotoxicity. II. To explore whether venlafaxine causes adverse events in this setting. III. To explore whether the neuropathy data provided by the Rydel-Seiffer graduated tuning fork is consistent with patient-reported outcome (PRO) measures of chemotherapy-induced peripheral neuropathy (CIPN) and whether this tool might cause different results in patients receiving venlafaxine versus placebo. OUTLINE: Patients are randomized to 1 of 2 treatment arms. ARM I: Patients receive venlafaxine orally (PO) twice daily (BID) beginning on day 1 of and continuing through completion of FOLFOX. ARM II: Patients receive placebo PO BID beginning on day 1 of and continuing through completion of FOLFOX. After completion of study treatment, patients are followed up at 1, 3, 6, 12, and 18 months.


Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.
