About this study

Official title: The Use of Calcium and Magnesium for Prevention of Ixabepilone Induced Peripheral Neuropathy: A Phase III Double-Blind Placebo Controlled Study

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.

Read the detailed description

PRIMARY OBJECTIVES:

  1. 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:

  1. 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Comparison of Chemotherapy-induced Peripheral Neuropathy Between Calcium With Magnesium (CaMg) and Placebo Arms, as Measured by the Sensory Subscale of EORTC QLQ-CIPN20

    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.

    Measured: During the first 18 weeks of ixabepilone-based therapy

Secondary outcomes (8)
  1. Percentage of Patients With Grade 2+ and/or Grade 3+ Neurotoxicity as Measured by NCI CTCAE Active Version Neuropathy Scale

    Measured: Up to 12 months from initiation of ixabepilone

  2. Time to Onset of Grade 2+ and/or Grade 3+ Neurotoxicity as Assessed by NCI CTCAE Active Version

    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.

    Measured: Up to 12 months from initiation of ixabepilone

  3. Proportion of Patients Undergoing Dose Reduction or Discontinuing Ixabepilone Secondary to Peripheral Neuropathy

    Measured: Up to 12 months from initiation of ixabepilone

  4. Average Cumulative Ixabepilone Dose

    Measured: Up to 12 months from initiation of ixabepilone

  5. Toxicity Profile of CaMg Per CTCAE Active Version

    Measured: Up to 12 months from initiation of ixabepilone

  6. Incidence of the Acute Pain Syndrome (APS)

    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.

    Measured: Treatment initiation to day 21 (Cycle 1)

  7. Severity of the Acute Pain Syndrome (APS)

    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.

    Measured: Treatment initiation to day 21 (Cycle 1)

  8. Association Between the Ixabepilone-APS and Eventual Chemotherapy-induced Neuropathy

    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.

    Measured: First cycle of therapy (up to 21 days)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Calcium Gluconate, Magnesium Sulfate and Quality-of-Life Assessment in people with Neuropathy and Pain, run by Mayo Clinic at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 4 Feb 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Aug 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

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). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Feb 2016.
