  Purpose
This randomized phase III trial studies calcium and magnesium to see how well they work in preventing peripheral neuropathy caused by ixabepilone in patients with breast cancer. Giving calcium together with magnesium may stop or delay the development of peripheral neuropathy in patients with cancer who are receiving treatment with ixabepilone. It is not yet known whether calcium and magnesium are effective in preventing peripheral neuropathy caused by ixabepilone.

Primary Outcome Measures:
  • Comparison of Chemotherapy-induced Peripheral Neuropathy Between Calcium With Magnesium (CaMg) and Placebo Arms, as Measured by the Sensory Subscale of EORTC QLQ-CIPN20 [ Time Frame: During the first 18 weeks of ixabepilone-based therapy ]
    European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Chemotherapy-Induced Peripheral Neuropathy Module (EORTC QLQ-CIPN20) sensor subscale score was calculated following the standard scoring algorithm and was transformed to a 0 to 100 scale with 0=Low QOL and 100=Best QOL for data analysis.


Secondary Outcome Measures:
  • Percentage of Patients With Grade 2+ and/or Grade 3+ Neurotoxicity as Measured by NCI CTCAE Active Version Neuropathy Scale [ Time Frame: Up to 12 months from initiation of ixabepilone ]
  • Time to Onset of Grade 2+ and/or Grade 3+ Neurotoxicity as Assessed by NCI CTCAE Active Version [ Time Frame: Up to 12 months from initiation of ixabepilone ]
    Time to onset of grade 2+ neurotoxicity was defined as time from randomization to the first occurrence of grade 2+ neurotoxicity. Time to onset of grade 3+ neurotoxicity was defined as time from randomization to the first occurrence of grade 3+ neurotoxicity.

  • Proportion of Patients Undergoing Dose Reduction or Discontinuing Ixabepilone Secondary to Peripheral Neuropathy [ Time Frame: Up to 12 months from initiation of ixabepilone ]
  • Average Cumulative Ixabepilone Dose [ Time Frame: Up to 12 months from initiation of ixabepilone ]
  • Toxicity Profile of CaMg Per CTCAE Active Version [ Time Frame: Up to 12 months from initiation of ixabepilone ]
  • Incidence of the Acute Pain Syndrome (APS) [ Time Frame: Treatment initiation to day 21 (Cycle 1) ]

    APS was measured using the pain item which evaluated the aches/pains at its WORST in the last 24 hours in the scale of 0 to 10, with 0=no aches/pain and 10=aches/pains as bad as can be.

    The outcome measures for each subsequent cycle will be analyzed in a similar fashion.


  • Severity of the Acute Pain Syndrome (APS) [ Time Frame: Treatment initiation to day 21 (Cycle 1) ]

    APS was measured using the pain item which evaluated the aches/pains at its WORST in the last 24 hours in the scale of 0 to 10, with 0=no aches/pain and 10=aches/pains as bad as can be.

    The outcome measures for each subsequent cycle will be analyzed in a similar fashion.


  • Association Between the Ixabepilone-APS and Eventual Chemotherapy-induced Neuropathy [ Time Frame: First cycle of therapy (up to 21 days) ]
    Correlation coefficients will be produced relating the worst pain scores in the first cycle of therapy and the subsequent neuropathy scores as judged from the daily and weekly questions.

Detailed Description:

PRIMARY OBJECTIVES:

I. To compare ixabepilone-induced peripheral neuropathy (sensory) as measured by European Organization for Research and Treatment of Cancer (EORTC) Quality of life Questionnaire (QLQ)-Chemotherapy-Induced Peripheral Neuropathy (CIPN)20 sensory subscale between calcium (Ca) Magnesium (Mg) and placebo arms.

SECONDARY OBJECTIVES:

I. To compare the incidence of CTCAE measured grade 2+ and/or grade 3+ peripheral neuropathy between CaMg and placebo arms.

II. To compare the times to onset of CTCAE measured grade 2+ and/or grade 3+ peripheral neuropathy between CaMg and placebo arms.

III. To compare the proportion of patients requiring ixabepilone dose reductions and/or stopping ixabepilone secondary to peripheral neuropathy (sensory) between CaMg and placebo arms.

IV. To assess the toxicity of CaMg in this situation. V. To document the incidence and severity of the acute pain syndrome (APS, commonly known as arthralgias/myalgias) induced by ixabepilone.

VI. To evaluate whether CaMg will decrease the acute pain syndrome (APS). VII. To evaluate the incidence and characteristics of, and change in, ixabepilone-APS over several cycles.

VIII. To evaluate the association between the ixabepilone-APS and eventual chemotherapy-induced neuropathy.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive calcium gluconate and magnesium sulfate IV over 30 minutes immediately before and after each ixabepilone administration.

ARM II: Patients receive placebo IV over 30 minutes immediately before and after each ixabepilone administration.

After completion of study treatment, patients are followed up monthly for 12 months.
