A Trial of Glutamine to Prevent Oxaliplatin Neurotoxicity and a Pharmacokinetic Analysis of Oxaliplatin

February 23, 2016 updated by: AHS Cancer Control Alberta

A Phase II Trial of Glutamin to Prevent Oxaliplatin Neurotoxicity and a Pharmacokinetic Analysis of Oxaliplatin.

The investigators hypothesize that glutamine significantly reduces the incidence and severity of peripheral neuropathy in patients receiving oxaliplatin for metastatic colorectal cancer, decreases the need for dose reduction of oxaliplatin, and it does not impair oxaliplatin efficacy or pharmacokinetics.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

  • The investigator is requested to advise the patient how to achieve an adequate contraception
  • Life expectancy longer than 6 months

Exclusion Criteria:

  • Patients who have received oxaliplatin previously
  • Patients with previous of current diagnosis of peripheral sensory neuropathy
  • Patients who have tested positive for HIV
  • Patients with other significant medical, psychiatric disorders that, in the opinion of the investigator, will exclude the patient from the study for compliance or safety reasons.
  • Patients who cannot swallow
  • History of known allergy to oxaliplatin or other platinum compounds, to 5-FU, to LV, glutamine or to any ingredients in the formulations of the containers
  • Participation in another clinical trial with any investigational drug within 30 days prior to study screening.
  • Pernicious anemia or other megaloblastic anemia with vitamin B12 deficiency
  • Patients with concomitant treatment with drugs/ingredients reported to have a potential activity to prevent PSN
  • Patients who haven't successfully completed local therapy for previously treated CNS metastases and who haven't been discontinued with corticosteroid for > 4wks before starting chemotherapy. Patients with asymptomatic brain mets. who have no evidence of midline shift on CT/ MRI may be enrolled without initiation of local therapy for the CNS mets. Repeat scan must be preformed < 4wks to ensure no progression.

Experimental: Dietary Supplement
Arm A: At cycle 2, patients will be randomized to receive for 6 days- Glutamine 30g/day during cycle 2 and glutamine 40g/day during cycle 3

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
To evaluate potential pharmacokinetic interactions between oxaliplatin and glutamine at 30g and 40g in patients with metastatic colorectal cancer.
Time Frame: Post cycle 2 and cycle 3
Post cycle 2 and cycle 3

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
To evaluate effects of glutamine supplementation on neuropathy and diarrhea related to oxaliplatin, and on dose reductions and in patients with metastatic colorectal cancer.
