INFUSE Morphine Study - Full Text View

Sponsor:	Halozyme Therapeutics
Information provided by:	Halozyme Therapeutics
ClinicalTrials.gov Identifier:	NCT00593281

Purpose

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 schedule.

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.
