简要总结
In cancer inpatient settings, intravenous (IV) opioids are frequently administered in a bolus fashion in order to obtain immediate pain relief. However, data on the abuse liability (AL) potential of IV opioids in cancer patients is limited. No study has investigated the effect of different IV infusion rates on AL potential in patients receiving parenteral opioids for pain control. This phase IV trial will determine the AL potential of a slow IV hydromorphone (SH) bolus administration compared with a fast IV hydromorphone (FH) bolus administration among inpatients with cancer pain. It will also determine the analgesic efficacy and adverse effect profiles of SH versus FH bolus infusions, and explore the relationship between pharmacogenetics and pharmacokinetic (PK) and pharmacodynamic (PD) effects of hydromorphone. This study will eventually help develop evidence-based guidelines regarding the best style of IV opioid administration which will achieve the most optimal pain control while avoiding the undesirable complication of nonmedical opioid use
详细描述
PRIMARY OBJECTIVE:
I. To compare the abuse liability potential of slow intravenous (IV) hydromorphone bolus infusion rate with fast IV hydromorphone bolus infusion rate among inpatients with breakthrough cancer pain (from the "DRUG LIKING" scale of the Drug Effects Questionnaire [DEQ] questionnaire).
SECONDARY OBJECTIVES:
I. To compare the abuse liability potentials of slow IV hydromorphone bolus with fast IV hydromorphone bolus among inpatients with breakthrough cancer pain (from the other scales of the DEQ questionnaire).
II. To compare the analgesic efficacy of slow IV hydromorphone bolus with fast IV hydromorphone bolus among inpatients with breakthrough cancer pain.

结局指标
主要结局
Abuse liability potential of SH bolus versus FH bolus (from the "DRUG LIKING" scale of the DEQ questionnaire)
时间窗: From baseline up to 120 minutes post intervention
This will be measured by: The difference of peak AL scores (maximum score assessed among the measures at 15, 30, 60, and 120 minutes per participant) of the 'drug LIKING' scale in the DEQ-5 questionnaire between the two treatment groups. (For each patient: difference = Max Scale SH+FP - Max Scale FH+SP). If no evidence of carryover effect, a paired t-test will be used. Otherwise a 2-sample t-test will be used only examining differences during the first period of treatment.
次要结局
- Adverse effect(From baseline up to 120 minutes post-intervention)
- Plasma concentration (Cmax) and peak (maximal) plasma concentration (Tmax) of hydromorphone metabolite H3G(From baseline up to 120 minutes post-intervention)

- Abuse liability potentials of SH bolus versus FH bolus (from the other scales of the DEQ questionnaire)(From baseline up to 120 minutes post intervention)
- Wild-type or single nucleotide polymorphisms (SNiPs) in UGT enzymes in the study population(From baseline up to 120 minutes post-intervention)
- Analgesic efficacy(From baseline up to 120 minutes post-intervention)
