Condition(s) targeted: Pain; Unspecified Adult Solid Tumor, Protocol Specific

Intervention: acetaminophen (Drug); codeine phosphate (Drug); dextropropoxyphene hydrochloride (Drug); morphine sulfate (Drug); oxycodone hydrochloride (Drug); management of therapy complications (Procedure); quality-of-life assessment (Procedure)

Phase: Phase 4

Status: Completed

Summary

RATIONALE: Oxycodone helps lessen pain caused by cancer and may improve quality of life. It is not yet known whether oxycodone works better and is more cost effective than standard therapy in treating patients with cancer pain. PURPOSE: This randomized phase IV trial is studying oxycodone to see how well it works compared with standard pain therapy in treating patients with cancer pain and if it is more cost effective than standard pain therapy.

Clinical Details

Official title: An Open, Randomized, Parallel Group Study in Patients With Cancer Pain, To Compare a Two-Step Analgesic Ladder (Non-Opioid to Oxycodone) With Conventional Management Using A Three-Step Approach

Study design: Allocation: Randomized, Masking: Open Label, Primary Purpose: Supportive Care

Primary outcome: Percentage of time in assessment periods 1 and 2 (i.e., first 4 weeks) with a Box-Scale (BS)-11 pain score of ≤ 4 (i.e., mild pain)

Secondary outcome:

Percentage of time in assessment periods 3 and 4 with a BS-11 pain score of ≤ 4

Mean BS-11 pain scores

Time to reach stable pain control

Mean escape medication use

Quality of sleep

Global assessment of pain relief with study drugs

Mean pain intensity, pain interference, and pain relief scores as measured by the Brief Pain Inventory

Overall number of phone calls, home visits by a nurse, home visits by a doctor, and unscheduled visits to a healthcare provider, related to pain control or analgesic medication during study treatment

Detailed description: OBJECTIVES: Primary

- Compare overall pain management in patients with cancer-related pain treated with

oxycodone hydrochloride vs standard three-step analgesic therapy.

- Compare the health economics of these regimens in these patients.

Secondary

- Explore the factors that inform patients' decisions about commencing opioid analgesia.

OUTLINE: This is an open-label, multicenter, randomized, parallel group, pilot study. Patients are randomized to 1 of 2 treatment arms.

- Arm I: Patients receive an analgesic regimen, according to their level of pain, for up

to 18 weeks.

- Step 1: Patients in mild pain receive oral acetaminophen 4 times daily.

- Step 2: Patients in mild-to-moderate pain receive oral codeine or oral

dextropropoxyphene hydrochloride 4 times daily and oral acetaminophen 4 times daily.

- Step 3: Patients in moderate-to-severe pain receive oral morphine or oral

oxycodone hydrochloride 6 times daily (every 4 hours) with or without a non-opioid analgesic. Patients may also receive an adjuvant drug (i. e., for side effects or for primary indication other than pain management that is analgesic in selected circumstances).

- Arm II: Patients receive oral oxycodone hydrochloride twice daily for up to 18 weeks.

Patients may receive a different opioid analgesic or analgesia or adjuvant medication as in arm I, if needed. Patients in both arms may also receive additional medication for breakthrough pain. Patients complete a patient-assessment booklet (PAB) daily which includes a Box-Scale (BS)-11 rating for average pain; questions regarding contact (e. g., telephone or visit) with healthcare professionals on that day; and information regarding the number of times escape medication is used. Quality of life and levels of cancer pain are assessed using the short form of the Brief Pain Inventory (BPI). After completion of study treatment, patients are followed at 4 weeks. Peer Reviewed and Funded or Endorsed by Cancer Research UK PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study.
