Brief summary
Safety and pharmacokinetics of an abuse-deterrent, extended-release formulation of morphine sulfate with a sequestered naltrexone core in children 7-17 with moderate-severe pain.
Detailed description
Subjects, once stabilized to Embeda, need only complete a minimum of 2 of the 6 week study duration to satisfy the PK endpoint. A safety follow-up visit is required at 1 week post-last dose.
Interventions
Oral/Capsule, once per day or twice per day dosing; Treatment duration consists of a 1 to 4 week Conversion/Titration Phase leading to a 2 to 6 week Maintenance Treatment duration.

Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes.
Time frame: Anytime post-dose on Visit 4 (Week 4)
Population: Data for this outcome measure was not collected, as there were insufficient pharmacokinetic samples due to early termination of the study by the sponsor.
Average Concentration at Steady-state (Css, av) of PF-06412528
Css, av was defines as the average steady state concentration of a drug (steady state has been achieved when the rate of drug administration and the rate of drug elimination are equal).

The scale ranges from 0 (none symptoms) to 48 (severe symptoms), higher score = more severe withdrawal. Scores category: 0 to 4 = none to minimal, 5 to 12 = mild, 13 to 24 = moderate, 25 to 36 = moderately severe withdrawal and 37 to 48 = severe withdrawal. Participants experiencing a COWS score greater than equal to (\>=) 13 is treated for opiate withdrawal signs and symptoms according to the investigator's medical judgment. In this outcome measure, participants as per COWS score categories are reported. Only those COWS categories are presented which had at least 1 participant for any reporting arm.
Time frame: Early Termination before Week 4 (anytime between Week 1 to Week 4)
Population: Analysis population included all participants who were screened and had received at least 1 dose of PF-06412528 from Week 1 to Week 4.

Number of Participants With Treatment Emergent Treatment Related Adverse Events: Week 5 to Week 10
An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. A treatment emergent AE was defined as an event that emerged during the treatment period that was absent before treatment, or worsened during the treatment period relative to the pretreatment state. Relatedness to PF-06412528 was assessed by the investigator.
Time frame: Week 5 to Week 10
Population: Analysis population included all participants who were screened and had received at least 1 dose of PF-06412528 from Week 5 to Week 10.

Apparent Volume of Distribution (Vz/F) of PF-06412528
Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.
Time frame: Anytime post-dose on Visit 4 (Week 4)
Population: Data for this outcome measure was not collected, as there were insufficient pharmacokinetic samples due to early termination of the study by the sponsor.
