Effect of Opioid Infusion Rate on Abuse Liability Potential of Intravenous Hydromorphone for Cancer Pain

December 23, 2025 updated by: M.D. Anderson Cancer Center

Effect of Opioid Infusion Rate on Abuse Liability Potential and Analgesic Efficacy of Intravenous Hydromorphone Among Inpatients With Cancer Pain: A Randomized Crossover Trial

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

Study Overview

Detailed Description

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.

III. To compare the adverse effects of slow IV hydromorphone bolus with fast IV hydromorphone bolus among inpatients with breakthrough cancer pain.

IV. To explore the abuse liability potential of slow IV hydromorphone bolus with fast IV hydromorphone bolus among the sub group of patients who achieved successful analgesia, defined as at least a two point or 30% reduction in pain intensity score on a 0-10 scale.

V. To obtain exploratory data regarding the relationship between pharmacogenetics and pharmacokinetic (PK) and pharmacodynamic (PD) effects of hydromorphone.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Abuse liability potential of SH bolus versus FH bolus (from the "DRUG LIKING" scale of the DEQ questionnaire)
Time Frame: 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.
From baseline up to 120 minutes post intervention

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Abuse liability potentials of SH bolus versus FH bolus (from the other scales of the DEQ questionnaire)
Time Frame: From baseline up to 120 minutes post intervention
This will be measured by: The differences of peak AL scores (maximum score assessed among the measures at 15, 30, 60, and 120 minutes per participant) of the FEEL drug effect, HIGH, DISLIKE and MORE items in the DEQ-5 questionnaire between the two treatment groups. (For each patient: difference = Max Scale SH+FP - Max Scale FH+SP). If carryover effect does not exist, a linear mixed effect model will be fitted for the outcome variable to assess if there is any treatment effect, after taking into account of the "sequence" and "period" effect. A random intercept due to patient will also be included.
From baseline up to 120 minutes post intervention
Analgesic efficacy
Time Frame: From baseline up to 120 minutes post-intervention

This will be measured by:

a) The change in NRS pain intensity scores from baseline to the lowest NRS pain score assessed among the measures 12, 30, 60, and 120 minutes post intervention in each treatment group. Wilcoxon rank-sum test will be used.

  1. Frequency of successful analgesia in each treatment group (successful analgesia is defined as at least a two point or 30% reduction in pain intensity score on a 1-10 scale1). The frequency will be estimated along with 95% confidence intervals. Logistic regression model will be applied to assess the effect of demographics and/or clinical measurements on successful analgesia.
  2. The mean time post-intervention until next analgesic dose is reported in each treatment sequence. Wilcoxon rank-sum test will be used.
From baseline up to 120 minutes post-intervention
Adverse effect
Time Frame: From baseline up to 120 minutes post-intervention

This will be measured by:

  1. The mean change scores (from baseline to the highest score assessed among the measures 12, 30, 60, and 120 minutes post intervention) of the adverse effects assessment scales. Wilcoxon rank-sum test will be used.
  2. of objective adverse effects (respiratory rate < 12 breaths/ minute, O2sat < 94%, SBP< 90mmHg, heart rate > 120 beats per minute) for each treatment group. Frequency and proportion of objective adverse effects will be reported and tabulated. Chi-squared test or Fisher's exact test, whichever appropriate, will be applied to test the association of adverse effect and treatment group.
From baseline up to 120 minutes post-intervention
Abuse liability potential among patients who achieved successful analgesia
Time Frame: From baseline up to 120 minutes post-intervention
This will be measured by: The peak scores of the five items in the DEQ-5 questionnaire for each treatment group among the subgroup of patients who achieved successful analgesia (defined as at least a two point or 30% reduction in pain intensity score on a 1-10 scale). Wilcoxon rank-sum test will be used.
From baseline up to 120 minutes post-intervention
Plasma concentration (Cmax) and peak (maximal) plasma concentration (Tmax) of hydromorphone metabolite H3G
Time Frame: From baseline up to 120 minutes post-intervention
This will be measured by estimating the mean Cmax and mean Tmax of hydromorphone and H3G in each treatment group among the measures at 15, 30, 60, and 120 minutes post intervention in each treatment group
From baseline up to 120 minutes post-intervention
Elimination half-life (T1/2) of hydromorphone and its metabolite H3G
Time Frame: From baseline up to 120 minutes post-intervention
This will be measured by estimating the mean T1/2 of hydromorphone and H3G among the measures at 15, 30, 60, and 120 minutes post intervention in each treatment group
From baseline up to 120 minutes post-intervention
Area-under-the-curve (AUC) of hydromorphone and its metabolite H3G
Time Frame: From baseline up to 120 minutes post-intervention
This will be measured by estimating the mean AUC of hydromorphone and H3G among the measures at 15, 30, 60, and 120 minutes post intervention in each treatment group
From baseline up to 120 minutes post-intervention
Metabolic ratio of H3G to hydromorphone
Time Frame: From baseline up to 120 minutes post-intervention
This will be measured by estimating the mean metabolic ratio of H3G to hydromorphone among the measures at 15, 30, 60, and 120 minutes post intervention in each treatment group
From baseline up to 120 minutes post-intervention
Wild-type or single nucleotide polymorphisms (SNiPs) in UGT enzymes in the study population
Time Frame: From baseline up to 120 minutes post-intervention
This will be measured by calculating number of wild-type or single nucleotide polymorphisms (SNiPs) in UGT enzymes in the study population
From baseline up to 120 minutes post-intervention
