Safety and Tolerability of Long-Term Administration of Hydromorphone HCI CR (Controlled Release)

Phase 3

Completed

• Conditions: Pain; Analgesics, Opioid

• Registration Number: NCT00410748
• Lead Sponsor: Alza Corporation, DE, USA

Brief Summary

The purpose of study was to characterize the safety and tolerability of long-term repeated dosing of OROS hydromorphone controlled release tablets (8,16,32, and 64 mg) in patients with chronic cancer pain or chronic non-malignant pain.

Detailed Description

This was a Phase 3, multicenter, open-label, extension study to characterize the safety and tolerability of long-term, repeated dosing of OROS hydromorphone in patients with chronic cancer or chronic non-malignant pain. Patients with chronic cancer or chronic non-malignant pain had completed an OROS hydromorphone short-term study (DO-104, DO-105, DO-119) of approximately 4 weeks duration. During this study, patients continued to receive the dose of OROS hydromorphone that they had been receiving in the short-term study, with dose adjustments as needed to control pain and adverse events. Patients were treated on an outpatient basis. The study was extended from 1 year to up to 2 years in duration. Monthly evaluations of patients treated with OROS hydromorphone for chronic pain were performed to identify adverse events, construct a safety and tolerability profile, and assess efficacy. Dose adjustments were permitted to provide for disease progression, pain control, and adverse events. Quarterly physical examinations were performed to detect significant changes in the underlying condition of patients or changes that may have been associated with long-term opioid therapy. OROS hydromorphone 24 hour controlled release tablets in 8, 16, 32 and 64 mg were ingested orally daily up to 1 year with dose adjustments as needed to control pain and adverse events.

Inclusion Criteria

• Patients who have chronic cancer or chronic non-malignant pain, including pain associated with AIDS, who have successfully completed a OROS hydromorphone HCI (controlled release) short-term study (i.e. Study DO-104, DO-105, or DO-119)

• Patients who are pregnant or breast-feeding
• Patients with any gastrointestinal disorder, including pre-existing severe GI narrowing (pathologic or iatrogenic) that may affect the absorption or transit of orally administered drugs

Primary Outcome Measures

Name	Time	Method
Effectiveness of OROS hydromorphone was maintained throughout the study. OROS hydromorphone provided moderate pain relief in patients with chronic cancer/chronic non-malignant pain.

Secondary Outcome Measures

Name	Time	Method
Long term administration of OROS hydromorphone was safe and well tolerated.
