Condition(s) targeted: Pain
Intervention: Hylenex (Drug)
Phase: Phase 3

Jay Thomas, M.D., Principal Investigator, Affiliation: San Diego Hospice

Double-blind study comparing the pharmacokinetics, safety and tolerability of morphine
administered subcutaneously (SC) with and without human recombinant hyaluronidase (HYLENEX)
and intravenously conducted in patients in a hospice care setting or through a palliative
care medicine setting. In this within-patient controlled study, each eligible study patient
receives a single injection by each of the three methods of morphine administration,
sequentially on three consecutive days, according to the order specified by a randomization
Each of the three injections consists of 5 mg of morphine (1. 0 mL of 5 mg/mL solution). The
HYLENEX injection will be 1 mL of 150 units. Although the IV administration will not be
blinded, the two SC injections will be double-blinded, using the same volume of normal saline
(0. 9% sodium chloride) placebo (1. 0 mL) as HYLENEX.
Official title: INcreased Flow Utilizing Subcutaneously Enabled Morphine (INFUSE-Morphine) With and Without Human Recombinant Hyaluronidase (HYLENEX) and Intravenously
Study design: Treatment, Randomized, Double Blind (Subject, Investigator), Placebo Control, Crossover Assignment, Pharmacokinetics Study
Primary outcome: • Determine the Tmax and other pharmacokinetic parameters of morphine injected subcutaneously with HYLENEX compared to without HYLENEX and injected
Secondary outcome: Compare the safety and tolerability of these three methods of injections
