Double Blind Efficacy and Safety Study of Flexible-Dose vs Low-Dose Q8003 After Undergoing Primary Unilateral Total Knee Arthroplasty
This is a Phase 3, two-arm, double-blind study of efficacy and safety of Q8003 in patients who have undergone primary unilateral total knee arthroplasty
This Phase 3 study is a two-arm, double-blind study to:
- compare the analgesic efficacy and safety of the flexible regimen of Q8003 (6 mg/4 mg up to 24 mg/16 mg) administered every 4-6 hours over a 48-hour Treatment Period versus low dose Q8003 (every 4-6 hours 3 mg/2 mg with a 6 mg/4 mg loading dose) to inpatients with moderate to severe postoperative pain who have undergone primary unilateral total knee arthroplasty.
- to evaluate the efficacy and safety of Q8003 when administered in the Voluntary Extension Period starting at 48 hours after the initial dosing and extending up to Day 12.
Allocation: Randomized, Control: Dose Comparison, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment
Flexible dose Q8003 (morphine sulfate and oxycodone hydrochloride), Low dose Q8003 (morphine sulfate and oxycodone hydrochloride)

Medical and Biotech [MESH] Definitions
Lethal Dose 50
The dose amount of poisonous or toxic substance or dose of ionizing radiation required to kill 50% of the tested population.
Maximum Tolerated Dose
The highest dose of a biologically active agent given during a chronic study that will not reduce longevity from effects other than carcinogenicity. (from Lewis Dictionary of Toxicology, 1st ed)
Administration of the total dose of radiation (RADIATION DOSAGE) in parts, at timed intervals.
Radiotherapy where there is improved dose homogeneity within the tumor and reduced dosage to uninvolved structures. The precise shaping of dose distribution is achieved via the use of computer-controlled multileaf collimators.
Dose-response Relationship, Immunologic
A specific immune response elicited by a specific dose of an immunologically active substance or cell in an organism, tissue, or cell.
This is a randomized, double-blind, multicenter, fixed dose factorial study of Q8003 12 mg/8 mg and Q8003 6 mg/4 mg versus its individual morphine sulfate and oxycodone hydrochloride compo...

RATIONALE: Methadone, morphine, or oxycodone may help relieve pain caused by cancer. It is not yet known whether methadone is more effective than morphine or oxycodone in treating pain in...
This is a Phase 3 double-blind, multiple dose safety extension study of Q8003 administered at daily doses up to 36 mg morphine/24 mg oxycodone (Q8003 36mg/24mg) over a treatment period of...
RATIONALE: Oxycodone helps lessen pain caused by cancer and may improve quality of life. It is not yet known whether oxycodone works better and is more cost effective than standard therapy...
Summary Oxycodone's respiratory profile (particularly the extent of respiratory depression in comparison to morphine) remains to be fully characterised in the peri-operative period. We randomly assign...
Studies have demonstrated that clonidine (α(2)-adrenoceptor and imidazoline receptor agonist) and BMS182874 (endothelin ET(A) receptor antagonist) potentiate morphine and oxycodone analgesia. Agmatin...
Mu-opioids (i.e. morphine, oxycodone, hydrocodone) are considered to be the primary drugs for treatment of moderate to severe acute, chronic and cancer pain. Despite their analgesic effectiveness they...
The opioids morphine and oxycodone are potent analgesics that are available as extended-release and immediate-release tablets. Indications are the same for both; i.e. severe acute pain and chronic pai...
OBJECTIVE: Oxycodone is widely used for the treatment of cancer pain, but little is known of its pharmacokinetics in cancer pain patients. The aim of this study was to explore the relationships betwee...
