Background: TJMUCH-GI-001 Trial was a randomized, double-blind, placebo-controlled phase III trial to study the efficacy of Monosialotetrahexosylganglioside (GM1) for oxaliplatin-induced peripheral neurotoxicity (OIPN) in GI cancer patients. Majority patients (> 80%) in both arms continued receiving oxaliplatin on the trial. The results showed GM1 effectively reduced OIPN in GI cancer patients. Here we report the survival and safety results of this trial. Methods: Patients were randomized in a 1:1 ratio to receive GM1 or placebo. Patients with OIPN > = G2 by CTCAE 4.03 persisting during or after oxaliplatin-based chemotherapy were eligible. The patients who remained on oxaliplatin after enrollment, received concurrent placebo or GM1 x 7 days with each chemotherapy cycle. The patients who stopped taking oxaliplatin, were treated with placebo or GM1 x 14 days every 3 weeks. GM1 was dosed at 60mg daily for every 3-week or 40mg daily for every 2-week schedule. Trial was continued until modified EORTC QLQ-CIPN20 ( MCIPN) increased by 30% or stayed unchanged after two more treatments beyond completion of oxaliplatin. Survival data for the treatment arms were compared using a log-rank test and Chi-square tests were used for safety analysis. Results: From May 2015 to Dec 2017, 73 patients were enrolled in GM1 and 72 in placebo arm. The median follow-up was 16.6 months (0.8-43.1 months) as of Dec.2018. Four patients lost to follow up. There was no deleterious impact of GM1 on survival. As a matter of fact, receiving GM1 was associated with a trend toward improved PFS and OS (HR=0.74,95%CI, 0.469 - 1.156 for PFS and HR=0.76, 95%CI0.469 - 1.156 for OS). The most frequent Grade 3 or 4 adverse events included neutropenia (8 patients in GM1 group VS. 4 in placebo group) and hypoleukemia (4 patients in GM1 group VS. 1 in placebo group). Other 3 or 4 adverse events (all less than 3 patients) included anorexia, hypercalcemia, nausea, vomiting, proteinuria, hyperbilirubinemia, hypokalemia, hypertension and appendicitis. All the 3 or 4 adverse events were related to chemotherapy, not to GM1. Conclusion: In this placebo-controlled phase III trial, GM1 showed acceptable toxicity with trends favorable PFS and OS in GI cancer patients. Clinical trial information: NCT02486198
