Prevention And Treatment Of Chemotherapy-Induced Peripheral Neuropathy In Subjects With Advanced Colorectal Cancer

Phase 4
Terminated
Conditions
Chemotherapy-Induced Peripheral Neuropathy
Interventions
Drug: Placebo
Registration Number
NCT00380874
Lead Sponsor
Pfizer's Upjohn has merged with Mylan to form Viatris Inc.
Brief Summary

Prevention and treatment of the severity of symptoms of chemotherapy-induced peripheral neuropathy.

Detailed Description

This study was terminated on July 15, 2008. The results of an interim analysis showed that the conditional power to detect a difference in treatment groups was insufficient to warrant study continuation and therefore termination of the trial was recommended. The decision to terminate the trial was not based on safety concerns.

Primary Outcome Measures
NameTimeMethod
Duration Adjusted Average Change (DAAC) of Paresthesia From the Onset of Chemotherapy Measured by Numeric Rating Scale (NRS)Period of 10 days from the onset of chemotherapy to the last cycle: Last Observation Carried Forward (LOCF)

Least squares mean of change: mean at cycle minus mean at Baseline. Paresthetic duration Adjusted Average Change (DAAC) endpoint was computed based on Numeric Rating Scale (NRS) of paresthesia (collected 0=no pain; 1-3=mild pain; 4-6=moderate pain; 7-10=severe pain). DAAC endpoint is defined as the Area Under Curve (AUC) of the collected NRS over time, divided by the collection time period (up to 10 days).

Secondary Outcome Measures
NameTimeMethod
Number of Participants With Persistent Paresthesic, Dysesthesic, and Pain SymptomsCycle 9 and Last Observation Carried Forward (LOCF) cycle endpoint

Number of participants with persistent paresthesic, dyesthesic, and pain symptoms at chemotherapy Cycle 9 and last observation carried forward (LOCF) endpoint. Numeric rating scale of symptoms: \>=1: mild symptoms to \>=4: moderate severe symptoms. Subjects rated their average severity of symptoms over the last 24 hours every evening before bedtime.

Duration Adjusted Average Change (DAAC) of Pain Symptom Score Within Each Cycle of Chemotherapy Measured by Numeric Rating Scale (NRS)Baseline to Cycle 9, LOCF cycle endpoint

Least squares (LS) mean of change: mean at cycle minus mean at Baseline. Pain Duration Adjusted Average Change (DAAC) endpoint was computed based on Numeric Rating Scale (NRS) of pain (collected 0=no pain; 1-3=mild pain; 4-6=moderate pain; 7-10=severe pain). DAAC endpoint was defined as the Area Under Curve (AUC) of the collected NRS over time, divided by collection time period (up to 10 days).

Change in Pain Scores Rated on Neuropathic Pain Symptom Inventory (NPSI) Subscales From Baseline CycleBaseline to Cycle 9, Last Observation Carried Forward (LOCF) cycle endpoint

Least squares (LS) mean of change: mean at cycle minus mean at Baseline. Neuropathic Pain Symptom Inventory (NPSI) = questionnaire designed to evaluate symptoms of neuropathic pain. 11-point numeric rating scale, range: 0 (no pain) to 10 (worst pain imaginable) best describing their average pain for last 24 hours.

Duration Adjusted Average Change (DAAC) of Paresthesic Symptom Score Within Each Cycle of Chemotherapy Measured by Numeric Rating Scale (NRS)Baseline to Cycle 9

Least squares mean of change: mean at cycle minus mean at Baseline. Paresthetic Duration Adjusted Average Change (DAAC) endpoint was computed based on Numeric Rating Scale (NRS) of paresthesia (collected 0=no pain; 1-3=mild pain; 4-6=moderate pain; 7-10=severe pain). DAAC endpoint is defined as the Area Under Curve (AUC) of the collected NRS over time, divided by collection time period (up to 10 days).

Duration Adjusted Average Change (DAAC) of Dysesthesia Symptom Score Within Each Cycle of Chemotherapy Measured by Numeric Rating Scale (NRS)Baseline to Cycle 9, LOCF cycle endpoint

Least squares (LS) mean of change: mean at cycle minus mean at Baseline. Dysesthesic Duration Adjusted Average Change (DAAC) endpoint was computed based on Numeric Rating Scale (NRS) of dysesthesis (collected 0=no pain; 1-3=mild pain; 4-6=moderate pain; 7-10=severe pain). DAAC endpoint was defined as the Area Under Curve (AUC) of the collected NRS over time, divided by collection time period (up to 10 days).
