A Repeated-Dose Evaluation of Analgesic Use and Safety of Dilaudid SR( Hydromorphone HCI) in Patients With Chronic Cancer Pain
This randomized (patients assigned to treatment by chance), single-blind (with respect to
dose), open-label (patients know what study treatment, not dose, they are receiving)
repeated dose study evaluating patients with chronic cancer pain was conducted in tandem
(together) with a similar protocol in patients with chronic non-malignant pain. A total of
463 patients were enrolled and evaluated in these studies. Patients receiving chronic
opioid therapy were converted to once daily OROS hydromorphone (slow release) using oral
morphine equivalents. Supplementary immediate-release (IR) hydromorphone was provided for
breakthrough pain. The dose of OROS hydromorphone (slow release) was escalated after every
2 days of therapy until no more than 3 doses of immediate-release (IR) hydromorphone were
required in a 24-hour period. Once a patient could be maintained on a stable dose of OROS
hydromorphone (slow release) for 3 consecutive days, the patient entered a 2-week
maintenance phase. Patients who completed the study were eligible for participation in an
OROS hydromorphone (slow release) long-term extension study, Study DO-109. The hypothesis
is the 24-hour controlled-release form of oral hydromorphone may provide consistent pain
relief, convenient dosing, and enhanced compliance while possibly decreasing the incidence
of side effects associated with peak (high) and trough (low) fluctuations in plasma drug
concentrations typically seen with immediate-release dosage formulations. Patients received
OROS Hydromorphone HCI (slow release) at Visit 2,3, and 4 (either 8,16,32, and/or 64mg
tablets) taken orally. OROS Hydromorphone HCI (slow release) doses were titrated after
every two days of therapy as necessary until dose stabilization occured, followed by a two
week Maintenance Therapy Phase.
Interventional
Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
No primary efficacy variable was defined in report. Protocol variables measured included: Total daily dose of OROS hydromorphone, daily use of rescue medication, daily pain relief scores, and time/number of steps needed for dose stabilization.
