Clinical trial to evaluate the efficacy and safety of E-52862 for reducing oxaliplatin-induced peripheral neuropathy in patients treated for colorectal cancer.

ABSTRACT: Primary objectives: ?To establish the efficacy of E-52862 to reduce the incidence and the severity of OXL-induced chronic neuropathy in patients treated for colorectal cancer.?To explore the efficacy of E-52862 to reduce the severity and duration of OXL-induced acute neuropathy.?To evaluate whether E-52862 can raise the cumulative total dose of OXL than can be delivered without dose-limiting chronic neuropathy.?To explore the incidence of dose-reduction, dose-delays and discontinuation of oxaliplatin due to symptomatic neuropathy grade 3 or 4.?To explore the incidence of adverse events by severity, of serious adverse events, of adverse events leading to E 52862 discontinuation and of adverse events related to E-52862 by severity.?To assess E-52862 plasma exposure associated with the treatment. Primary endpoints: Efficacy endpoints:-Evolution of the clinical Total Neuropathy Score (cTNS).-Change from baseline of the reduced Total Neuropathy Score (rTNS).-Evolution of cold-induced pain intensity.-Change from baseline of the number and duration of signs and symptoms of OXL-induced acute neuropathy assessed with the specific OXL-induced neuropathy questionnaire.-Level of peripheral sensory neuropathy toxicity at each visit assessed with the National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) criteria.-Time to the first occurrence of NCI-CTCAE grade 2, 3 or 4 symptomatic neuropathy.-Change from baseline of the amplitudes of sensory and motor nerve action potentials and of the sensitive and motor nerve conduction velocities measured in the nerve conduction tests.-Evolution of patients’s quality of life assessed with the Quality of Life Questionnaire C30 (QLQ-C30) with the module for chemotherapy-induced neuropathy (QLQ-CIPN20).-Proportion of patients who meet any of the following definitions of neuropathy at the end of the study: a) at least subclinical neuropathy: cTNS >2, b) manifest neuropathy: rTNS > or equal 5, c) symptomatic neuropathy: grade >1 NCI-CTCAE toxicity, and d) severe neuropathy: grade > or =3 NCI-CTCAE toxicity.-Incidence of dose-reduction, dose-delays and discontinuation of oxaliplatin due to symptomatic neuropathy grade 3 or 4.-Total cumulative dose of OXL administered. Safety endpoitns:-Incidence of adverse events by severity, of serious adverse events, of adverse events leading to E-52862 discontinuation and of adverse events related to E-52862 by severity. Values for these variables will be obtained in all visits of the study, except in the screening visit.-E-52862 plasma concentration associated with the treatment.

Project description:Intervention 1: Intervention group: Treatment with melatonin will be started on the evening of the first chemotherapy dose and continue through 1 month following the last dose of chemotherapy or 6 months after starting melatonin (each one goes earlier). During this period, patients will consume 20 mg of melatonin (4 capsules, each one contains 5mg melatonin) every evening. Melatonin capsule will be supplied by Zahravi Pharmaceutical Company. Intervention 2: Control group: Treatment with melatonin will be started on the evening of the first chemotherapy dose and continue through 1 month following the last dose of chemotherapy or 6 months after starting melatonin/placebo (each one goes earlier). During this period, patients will consume 4 capsules of placebo every evening. Placebo capsules will be supplied by Zahravi Pharmaceutical Company and will be the same as melatonin. Primary outcome(s): Percent of grade 2 and 3 neuropathy according to National Cancer Institute’s Common Toxicity Criteria for adverse events (NCI-CTCAE V.4) will be compered among the two study groups (case and control), as the main outcome of the study. Timepoint: Prior to the start of study; during the chemotherapy (prior to receiving each cycle); 1 month after receiving the last dose of chemotherapy or 6 months after initiation of melatonin (each one happens earlier). Method of measurement: National Cancer Institute’s Common Toxicity Criteria for adverse events (NCI-CTCAE V.4) scale will be used by the oncologist to evaluate severity of neuropathy in the patients. According to this scale severity of neuropathy will be classified from 1 to 5. Study Design: Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Prevention, Randomization description: Randomization will be done by block-permutation method, considering 8 blocks, each one consisting 10 patients. Random Allocation software will be used to allocate patients to drug or placebo group. Randomization and allocation will be done by one of the researchers who has no role in the treatment and evaluation of the patients, and also analysis of data, Blinding description: Randomization and allocation will be done by one of the researchers who has no role in the treatment and evaluation of the patients, and also analysis of data. Drug (melatonin) and placebo packaging will be similar and will not be distinguishable by physician and patients who receive them. During the study, melatonin and placebo will be supplied by the same company.
