Oxaliplatin-induced neuropathy is a major dose-limiting side effect in patients with colorectal cancer treated with the FOLFOX chemotherapy regimen. Hypersensitivity to cold is the sensory hallmark of oxaliplatin-induced neuropathy, and it can predict the development of long-term neuropathy. In this study, the investigators aim to determine whether intravenous lidocaine can prevent oxaliplatin-induced cold hypersensitivity.
Colorectal cancer is the third leading cause of cancer death in the United States, with an estimated incidence of 130.000 cases per year. Oxaliplatin is the first-line chemotherapy regimen for gastro-intestinal cancers. Despite its efficacy, oxaliplatin causes peripheral neuropathy in 72% of the treated patients. Acute oxaliplatin-induced peripheral neuropathy [OIPN] is the most common dose-limiting side effect of oxaliplatin and characterized by profound cold allodynia in the extremities. In about 21% of the patients acute OIPN exacerbates into chronic neuropathic pain, which is treatment resistant to currently approved drugs, pointing towards a great need to identify an effective strategy in preventing OIPN. Recent literature suggests that certain methods of assessing sensory nerve function in neuropathic pain patients may provide a prediction to an individual analgesic response; however, no placebo-controlled studies have been performed with the primary goal of identifying treatment response predictors in preventing OIPN.
In this pilot study we will both determine the tolerability and the efficacy of intravenous Lidocaine, for preventing oxaliplatin-induced cold hypersensitivity in the setting of mFOLFOX6 chemotherapy for advanced colorectal cancer.
The proposed study will be conducted in two phases. The tolerability phase is an open-label study to determine the tolerable dose regimen of IV lidocaine in patients with advanced colorectal cancer receiving oxaliplatin chemotherapy. The efficacy pilot phase is a randomized, double-blinded, controlled study comparing the outcomes between IV lidocaine versus placebo in the same setting of colorectal cancer. Consented subjects will attend a screening visit and six intervention visits, during which they will undergo sensory testing and receive intravenous lidocaine or placebo infusion. Cold hypersensitivity and spontaneous pain will be assessed at baseline, daily for 12 weeks and at follow-up visits. At enrollment, each patient will be assigned a study number, which will match a previously prepared computer-generated list of randomization numbers to determine the interventions lidocaine or placebo. The participants and all other study personnel will be blinded to the treatment allocation.

| Lidocaine Hydrochloride | Drug | Intravenous lidocaine will be dosed as a brief 1 mg/kg infusion (based on Ideal Body Weight (IBW)) over 10 minutes, followed by a 0.04 mg/kg/min infusion over additional 120 minutes, resulting in a total dose of 5.8 mg/kg IBW. If this dose is tolerable in four consecutive sessions of mFOLFOX6 in six or more of the eight patients in the tolerability phase, we will initiate the randomized efficacy pilot study. |
| Measure | Description | Time Frame |
|---|---|---|
| Area Under the Curve (AUC) of Intensity of Oxaliplatin-induced Cold Pain/Unpleasantness vs Time | The intensity of cold pain and cold unpleasantness is evaluated separately, assessed daily on a 0-10 scale, upon holding a pre-cooled (~8°C) metal cylinder for 10 seconds. the area under the curve of cold pain and cold unpleasantness vs time is calculated per chemotherapy cycle (every two weeks) and serves as a primary outcome measure. For intervention (lidocaine+FOLFOX) and control (placebo+FOLFOX) groups, the average of cold pain AUC and cold unpleasantness AUC over 7 cycles was calculated. The average AUCs over 7 cycles were compared between study arms. The AUC is measured as a score on a 0-10 scale multiplied by 14 days and may range between 0 and 140. Higher AUC values represent more intense cold pain/unpleasantness. | 14 weeks |

EORTC QLQ-CIPN20 ranges from 0 (no symptoms) to 100 (worst symptoms). A higher score represents worse neuropathy. The changes in scores are compared between study arms. EORTC QLQ-CIPN20 tool is a quality of life questionnaire (QLQ) from the European Organization for Research and Treatment of Cancer (EORTC) for evaluation of CIPN. |
