Safety and Pharmacokinetic Study of Oral Morphine Sulfate in Pediatric Subjects

Completed · Phase 4

Conditions studied: Pain

In brief

The purpose of this study is to evaluate the tolerability and safety of oral morphine sulfate in the treatment of postoperative pain in different pediatric age groups following multiple-dose administration. To determine multiple-dose pharmacokinetics (PK) of morphine sulfate in pediatric subjects. To compare plasma concentration of morphine sulfate in each age group of pediatric subjects with adult plasma morphine sulfate concentrations.

Who can join

Age: 2 and older, up to 17. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• parent or guardian provided written parental permission/informed consent, with subject assent (if required by local IRB).
• The child is 2 years old through 17 years old, inclusive (at the time of informed consent signing).
• A routine pediatric procedure is expected to require inpatient hospitalization postoperatively.
• Must be an inpatient for the study treatment period.
• Is expected by the investigator to require use of oral opioid for the treatment of postoperative pain.
• Has the ability to read and understand the study procedures and has the ability to communicate meaningfully with the study investigator and staff (if the subject is of preverbal age or cannot read or communicate meaningfully, then the subject's parent or guardian must meet this criterion).
• Child is expected to experience moderate to severe postoperative pain, in the investigator's opinion, during the immediate postoperative period after discontinuation of intermittent administration of IV opioid (preferably morphine) and is able to tolerate oral medications.
• If female subject is of childbearing potential, she must have a negative pregnancy test result at screening (serum) and on the day of surgery prior to surgery (urine).
• Must have vascular access to facilitate blood draws.

You may not qualify if…

• Has significant medical disease(s), laboratory abnormalities, or conditions(s) that in the investigator's judgment could compromise the subject's welfare, ability to communicate with study staff, complete study activities, or would otherwise contraindicate study participation. There is no minimum value for SpO2 for inclusion in the study; this should be based on the investigator's judgment.
• Has used opioids chronically (e.g., codeine, morphine, oxycodone, or hydromorphone, for >7 calendar days) within the previous 30 days.
• Has known hypersensitivity or contraindication to receiving oral opioid(s).
• Has a current active enteral malabsorption disorder.
• Has impaired liver function (e.g., alanine aminotransferase [ALT] ≥3 times the upper limit of normal [ULN], or bilirubin ≥3 times ULN), known active hepatic disease (e.g., hepatitis), evidence of clinically significant chronic liver disease or other condition affecting the liver (e.g., chronic hepatitis) that may suggest the potential for an increased susceptibility to hepatic toxicity with oral morphine exposure. Subjects with no previous history of liver function impairment may be enrolled prior to receipt of screening laboratory testing results.
• Has significantly impaired renal function or disease, as evidenced by an estimated glomerular filtration rate (i.e., from creatinine levels using the Schwartz formula) calculated to be less than one-third of normal for the applicable age of this study population. Subjects with no previous history of kidney function impairment may be enrolled prior to receipt of screening laboratory testing results.
• Has a history of substance abuse or there is evidence of current substance abuse, in the investigator's opinion.
• Has received epidural or regional anesthesia within 12 hours prior to the first dose of oral morphine sulfate.
• Has participated in an interventional clinical study (investigational or marketed product) within 30 days before screening, or plans to participate in another clinical trial in the next 30 days.
