Condition(s) targeted: Pain Management

Intervention: Hylenex recombinant , morphine, saline (Drug); Saline (Other)

The overall aim of this study is to find out whether Hylenex recombinant (for short, Hylenex) in subcutaneous (SC) injection improves the speed and effectiveness of SC opioids in hospice patients. Specifically, this study proposes to compare the level of self-reported pain in hospice patients started on SC infusions of morphine and hydromorphone (Dilaudid) over the initial 8 hours of opioid infusion with and without the preceded co-injection of Hylenex. Hospice patients include both home-bound patients as well as those under intensive care in hospice houses.

Clinical Details

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: The primary outcome measure will be the sum of 7 pain intensity differences (SPID) computed from 8 observations of pain during the 8-hour period.

Secondary outcome:

The secondary outcome measure will be the sum of distress level differences (SDLD), sum of relief level differences (SRLD), and sum of bolus attempts (SBAM) made during the same 8-hour period.

The mean number of bolus attempts made over the 8-hour period between experimental and control groups.

Detailed description: As of January 2009, 58 patients were recruited to the study as study subjects. Target goals for the study is to recruit 88 subjects with full and accurate information with about 44 patients in the Hylenex group and another group of subjects in the control group.
