Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
One participant was recruited between November 2009 and July 2010 at Mayo Clinic. This trial was terminated in July 2010 due to lack of accrual. Since only one patient was accrued, patient confidentiality prevents the reporting of this patient.

  Outcome Measures
  Show All Outcome Measures

1.  Primary:   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 ]

2.  Secondary:   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 ]

3.  Secondary:   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 ]

4.  Secondary:   Proportion of Patients Undergoing Dose Reduction or Discontinuing Ixabepilone Secondary to Peripheral Neuropathy   [ Time Frame: Up to 12 months from initiation of ixabepilone ]

5.  Secondary:   Average Cumulative Ixabepilone Dose   [ Time Frame: Up to 12 months from initiation of ixabepilone ]

6.  Secondary:   Toxicity Profile of CaMg Per CTCAE Active Version   [ Time Frame: Up to 12 months from initiation of ixabepilone ]

7.  Secondary:   Incidence of the Acute Pain Syndrome (APS)   [ Time Frame: Treatment initiation to day 21 (Cycle 1) ]

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

9.  Secondary:   Association Between the Ixabepilone-APS and Eventual Chemotherapy-induced Neuropathy   [ Time Frame: First cycle of therapy (up to 21 days) ]
