D-cycloserine in the Management of Chemotherapy-Induced Peripheral Neuropathic Pain

November 25, 2013 updated by: Northwestern University

A Phase III Study of D-Cycloserine in the Management of Paclitaxel-Induced Peripheral Neuropathic Pain in Breast Cancer Patients

D-cycloserine may help lessen pain and other symptoms of peripheral neuropathy caused by chemotherapy. It is not yet known whether D-cycloserine is more effective than a placebo in treating peripheral neuropathy caused by chemotherapy.

This randomized, double-blind, placebo-controlled clinical trial was designed to study D-cycloserine at 2 different doses to see how well each works compared to the other and to a placebo in treating cancer patients with peripheral neuropathy caused by chemotherapy.

Detailed Description

This is a randomized, double-blind, placebo-controlled study. Initially, patients were randomized to 1 of 2 treatment arms (D-cycloserine 250 mg twice daily or placebo twice daily), and treated for up to 4 weeks in the absence of unacceptable toxicity.

Later, the design was changed to randomize patients to 1 of 3 arms as follows:

  • D-cycloserine 50 mg twice daily for up to 12 weeks
  • D-cycloserine 200 mg twice daily for up to 12 weeks
  • Placebo twice daily for up to 12 weeks

Description

Inclusion Criteria:

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Difference in Patient-reported Pain Intensity Scores Between the 3 Arms After the Treatment Period Using the Brief Pain Inventory
Time Frame: From the date that the first patient is registered until the last patient completes the 12 weeks of study intervention (approximately 1 year)
Compare patient-reported pain intensity scores after the treatment period (12 weeks) between the 3 arms of the trial.
From the date that the first patient is registered until the last patient completes the 12 weeks of study intervention (approximately 1 year)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Individual Patients' Self-reported Overall Pain Relief Scores Before and After the Treatment Period
Time Frame: From the date that the first patient is registered until the last patient completes the 12 weeks of study intervention (approximately 1 year)
Compare individual patients' self-reported pain relief scores before and after the treatment period.
From the date that the first patient is registered until the last patient completes the 12 weeks of study intervention (approximately 1 year)
Change in Neuropathic Pain Scores in and Between Study Arms Using the Neuropathic Pain Inventory, the FACT-Taxane, and the Leonard Scale.
Time Frame: From the date that the first patient is registered until the last patient completes the 12 weeks of study intervention (approximately 1 year)
Compare changes in neuropathic pain scores within each arm, as well as between the 3 arms of the study. Neuropathic pain will be assessed using 3 tools: the Neuropathic Pain Inventory, the FACT-Taxane, and the Leonard Scale.

Differences in Pain Interference Between Study Arms Using the Brief Pain Inventory and the FACT-Taxane
Time Frame: From the date that the first patient is registered until the last patient completes the 12 weeks of study intervention (approximately 1 year)
Compare the pain interference scores after study treatment between study arms using the brief pain inventory and the FACT-Taxane.
From the date that the first patient is registered until the last patient completes the 12 weeks of study intervention (approximately 1 year)
Change in the Amount of Opioid Medication Used by Patients in Each Arm Before and After Study Treatment
Time Frame: From the date that the first patient is registered until the last patient completes the 12 weeks of study intervention (approximately 1 year)
Record the amount of opioid medication used by patients in each arm before and after the study treatment period.
