Effectiveness Assessment of Riluzole in the Prevention of Oxaliplatin-induced Peripheral Neuropathy.

Phase 2

Suspended

• Conditions: Oxaliplatin-induced Peripheral Neuropathy
• Interventions: Drug: Placebo Oral Tablet; Drug: Riluzole

• Registration Number: NCT03722680
• Lead Sponsor: UNICANCER

Brief Summary

It is a phase II trial, randomized, parallel, double blind, multicenter, comparing riluzole versus placebo.

The trial population is composed of patients ≥18 years old that have developed stage II/III colorectal cancer and are eligible for Simplified FOLFOX4 (6-12 cycles) adjuvant chemotherapy.

The primary objective is to assess the preventive efficacy of riluzole on the severity of oxaliplatin-induced peripheral neuropathy during the Simplified FOLFOX4 adjuvant chemotherapy of stage II/III colorectal cancers.

Arm && Interventions

Group	Intervention	Description
Placebo	Placebo Oral Tablet	Posology, administration and duration of treatment will be equivalent to riluzole group.
Riluzole	Riluzole	The patient will be taken one tablet twice a day, in the morning and in the evening during the meal (12h interval). The medication is taken during the 14 days of each chemotherapy cycle, beginning 7 days before the start of chemotherapy and ending 2 weeks after the start of last cycle of chemotherapy (25 weeks). The treatment ends with the cessation of chemotherapy (visit V3 or anticipated stop).

Primary Outcome Measures

Name	Time	Method
Quality of life questionnaire-chemotherapy-induced peripheral neuropathy (QLQ-CIPN20)	3 months afer initiation of oxaliplatin based chemotherapy (1 cycle = 14 days)	QLQ-CIPN20 Questionnaire (EORTC): Self-reported questionnaire consisting of 20 questions that assess the symptoms and functional limitations of chemotherapy-induced peripheral neuropathy. The questionnaire is divided in 3 subscales: sensory, motor, and autonomic and gives a comprehensive picture of the nature, frequency, and severity of chemotherapy-induced peripheral neuropathy (CIPN). Using a 4-point Likert scale (1 = "not at all," 2 = "a little," 3 = "quite a bit," and 4 = "very much"), patients indicate the degree to which they have experienced sensory, motor, and autonomic symptoms.

Secondary Outcome Measures

Name	Time	Method
National Cancer Institute - Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0	throughout study completion, assessed up to 43 months	The NCI-CTCAE v5.0 is widely accepted in the community of oncology research as the leading rating scale for adverse events. This scale will assess the severity of sensory neuropathic disorders, this derivative into 5 grades determined by the investigator.
Douleur Neuropathique 4 (DN4) questionnaire (interview portion)	This evaluation will be carried out only if the item 5 of BPI "general pain felt in the last 7 days" is ≥4/10.	The interview portion of the DN4 questionnaire is a clinician-administered screening tool for neuropathic pain. The questionnaire includes 7 items, grouped into two questions. Each item, is answered as either YES or NO. A final cumulative patient's score is obtained by allocating 1 point for each YES and 0 point for each NO. If the patient's score is ≥3/7, the test is positive.
QLQ-C30 questionnaire (EORTC)	At inclusion (V0), 3 months (V2), up to 7 months (V3), up to 9 months (V4), up to 12 months (V5), up to 15 months (V6), and up to 18 months (V7) after initiation of oxaliplatin based chemotherapy.	This self-reported questionnaire assesses the health-related quality of life of cancer patients in clinical trials.; The questionnaire includes five functional scales (physical, everyday activity, cognitive, emotional, and social), three symptom scales (fatigue, pain, nausea and vomiting), a health/quality of life overall scale, and a number of additional elements assessing common symptoms (including dyspnea, loss of appetite, insomnia, constipation, and diarrhea), as well as, the perceived financial impact of the disease.; All of the scales and single-item measures range in score from 0 to 100. A high scale score represents a higher response level.
QLQ-CIPN20	At inclusion (V0), 3 months (V2), up to 7 months (V3), up to 9 months (V4), up to 12 months (V5), up to 15 months (V6), and up to 18 months (V7) after initiation of oxaliplatin based chemotherapy.	Self-reported questionnaire consisting of 20 questions that assess the symptoms and functional limitations of chemotherapy-induced peripheral neuropathy. The questionnaire is divided in 3 subscales: sensory, motor, and autonomic and gives a comprehensive picture of the nature, frequency, and severity of CIPN. Using a 4-point Likert scale (1 = "not at all," 2 = "a little," 3 = "quite a bit," and 4 = "very much"), patients indicate the degree to which they have experienced sensory, motor, and autonomic symptoms.
Disease progression	From date of randomisation until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 43 months.	Disease Free Survival, defined as the interval between the date of randomization and the date of cancer relapse (local, regional, metastases, second cancer) or death from any cause, whichever occurs first.
Quantification of chemotherapy dose reductions	3 months (V2) and up to 7 months (V3) after initiation of oxaliplatin based chemotherapy.	The number of chemotherapy dose reduction caused by severe neuropathy and/or poor tolerance of treatment will be recorded.
Quantification of cumulative dose	3 months (V2) and up to 7 months (V3) after initiation of oxaliplatin based chemotherapy.	The cumulative dose (mg/m²) of chemotherapy delivered to patients will be recorded.
Evaluation of study exit rates	3 months (V2) and up to 7 months (V3) after initiation of oxaliplatin based chemotherapy.	The study exit rate caused by severe neuropathy and/or poor tolerance of treatment will be recorded.
Brief Pain Inventory (BPI) questionnaire	At inclusion (V0), 3 months (V2), up to 7 months (V3), up to 9 months (V4), up to 12 months (V5), up to 15 months (V6), and up to 18 months (V7) after initiation of oxaliplatin based chemotherapy.	This self-report questionnaire includes: * A body schema; * The maximum pain, lowest pain, usual pain within the last 15 days (Numerical Numeric rating scales (NRS) 0 to 10; * Description of current analgesic treatment,; * An assessment of relief by a percentage scale (0-100%), Assessment of the impact of pain on: mood, relationships with others, walking, sleep, work, happiness the joy - of living, recreation, activities in general (digital scales, rating from 0 \[normal\] to 10 \[no activity\]).
Neuropathic Pain Symptom Inventory (NPSI) questionnaire	This evaluation will be carried out only if the item 5 of BPI "general pain felt in the last 7 days" is ≥4/10.	This self-reported questionnaire assesses different neuropathic pain symptoms. The French NPSI includes 12 items that discriminates and quantifies five distinct dimensions of neuropathic pain. Each of these items are quantified on a (0-10) numerical scale.
Time to HRQoL score deterioration	At inclusion (V0), 3 months (V2), up to 7 months (V3), up to 9 months (V4), up to 12 months (V5), up to 15 months (V6), and up to 18 months (V7) after initiation of oxaliplatin based chemotherapy.	The interval between randomization and deterioration ≥5 points in the HRQoL score as compared to baseline score or death (all causes).
Assessment of glutamate serum level	Glutamate serum level will be dose at inclusion (V0), 3 months (V2), up to 7 months (V3), and up to 18 months (V7) after initiation of oxaliplatin based chemotherapy.	Correlation with colorectal cancer tumors/nodes/metastases (TNM) score (and eventually neuropathic symptoms), glutamate plasmatic
