Study Evaluating Neurotoxicity in Patients with Metastatic Gastro Intestinal Cancer Taking Phycocare® or Placebo During Oxaliplatin Based Chemotherapy
- Conditions
- Metastatic Gastric Cancer

- Other: PlaceboOther: Phycocare
- Registration Number
- NCT05025826
- Lead Sponsor
- Nantes University Hospital
- Brief Summary
Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most frequent side effects caused by antineoplastic agents, with a prevalence from 19% to over 85%. Clinically, CIPN is a mostly sensory neuropathy that may be accompanied by motor and autonomic changes of varying intensity and duration.
Due to its high prevalence among cancer patients, CIPN constitutes a major problem for both cancer patients and survivors as well as for their health care providers, especially because, at the moment, there is no single effective method of preventing CIPN; moreover, the possibilities of treating this syndrome are very limited.
The phycocyanin (PC), a biliprotein pigment and an important constituent of the blue-green alga Spirulina platensis, has been reported to possess significant antioxidant and radical-scavenging properties, offering protection against oxidative stress.
Study hypothesis is that phycocyanin may give protection against oxaliplatin-induced neuropathy in the treatment of gastro intestinal cancers including oesogastric, colo-rectal and pancreatic cancers. This trial will be a randomised placebo-controlled study.
- Detailed Description
The phycocyanin used in this protocol (Phycocare®) will be 5 times more concentrated than the Spirulysat (food supplement commercialized by Algosource).
It will be administrated during Oxaliplatin based chemotherapy and 3 months after oxaliplatin stopped.

Group Intervention Description Placebo Placebo Placebo during 12 cycles of 13 days from day -3 before cycle 1 of oxaliplatin based chemotherapy until 3 months after the last dose of oxaliplatin (9 months). From D-3 to D13 before cycle 1 chemotherapy: patient will take Placebo From D1 to D13 of cycle 2 chemotherapy and further chemotherapy cycles : patient will take Placebo. On days of chemotherapy the patient does not take Placebo Phycocare Phycocare PHYCOCARE during 12 cycles of 14 days from day -3 before oxaliplatin based chemotherapy until cycle 3 months after the last dose of oxaliplatin (18 cycles, about 9 months) From D-3 to D14 before cycle 1 chemotherapy: patient will take Phycocare From D1 to D14 of cycle 2 chemotherapy and further chemotherapy cycles : patient will take Phycocare On days of chemotherapy the patient does not take Phycocare

Name Time Method Demonstrate a 50% decrease of the grade> or = 2 neurotoxicity at 4 months after oxaliplatin-based chemotherapy start in the PHYCOCARE arm 4 months after oxaliplatin-based chemotherapy start neurotoxicity according to NCI (National Cancer Institute) criteria in both arms
- Secondary Outcome Measures
Name Time Method Comparison between the two arms of percentage of patients who stopped oxaliplatin for neurological toxicity last day of chemotherapy Delay of definitive interruption or decrease of oxaliplatin treatment

Comparison between the two arms of Patient 's Quality of Life according with EORTC-QLQ-C30 end of study visit (an average of 9 months after cycle 1 day1) QLQ C30 - score questions 1 to 28: score frame \[30-114\] . 30= good quality of life questions 29 and 30 : score frame \[2-14\] . 2 = bad quality of lifre
