Not Applicable

Completed

Conditions: Peripheral Neuropathy

Interventions: Drug: placebo
Drug: venlafaxine
Other: questionnaire administration
Other: quality-of-life assessment

Registration Number: NCT01611155

Lead Sponsor: Mayo Clinic

Brief Summary: 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)

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.

Primary Outcome Measures

Name	Time	Method
Cycle 1 Sensory Neuropathy Score (Items 31-36, 39, 40 and 48) of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-CIPN20	Up to 2 weeks	The EORTC QLQ-CIPN20 sensory neuropathy score will be calculated using the standard algorithm of EORTC QLQ-CIPN20 and transformed into a 0-100 point scale, where high scores meant less symptom burden. The changes of sensory neuropathy from baseline will be derived by subtracting the baseline score from the sensory neuropathy scores at each cycle of evaluation.

Secondary Outcome Measures

Name	Time	Method
Cycle 1 Acute Neuropathy as Measured by EORTC QLQ CIPN20 Motor Subscale (Items 37, 38, 41-45 and 49), and Autonomic Scale (Items 46, 47, 50)	Up to 2 weeks	The EORTC QLQ-CIPN20 motor and autonomic neuropathy scores will be calculated using the standard algorithm of EORTC QLQ-CIPN20 and transformed into a 0-100 point scale, where high scores meant less symptom burden. The changes of sensory neuropathy from baseline will be derived by subtracting the baseline score from the sensory neuropathy scores at each cycle of evaluation.
