Clinical Trial Summary

Safety and pharmacokinetics of an abuse-deterrent, extended-release formulation of oxycodone hydrochloride with a sequestered naltrexone core in children 7-17 with moderate-severe pain.

Description:

This is a multicenter, open-label, single-arm study designed to characterize the PK and to evaluate the safety of ALO-02 in children and adolescents 7 to 17 years of age who require opioid analgesia for moderate-to-severe pain. The study consists of 4 study periods (screening, titration, maintenance, follow-up) occurring over a period of up to 9 weeks. The study will enroll approximately 140 children and adolescents with at least 100 subjects once stabilized during the titration period to complete a minimum of 2 of the 4 weeks study duration in the maintenance period to satisfy the PK endpoint. A safety follow-up visit is required at 1 week post-last dose.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Average Steady-state Concentration (Css, av) of Oxycodone	ALO-02 capsules consist of controlled-release pellets containing oxycodone hydrochloride (HCl) and naltrexone HCl. Oxycodone is a main component of this product.	Visit 4 (Day 21,28,35 or 42) or Visit 5 if not collected at Visit 4 (early termination or end of study, which occurred on Day 35,42,49 or 56) in Maintenance Phase
Primary	Apparent Oral Clearance (CL/F) of Oxycodone	ALO-02 capsules consist of controlled-release pellets containing oxycodone hydrochloride (HCl) and naltrexone HCl. Oxycodone is a main component of this product.	Visit 4 (Day 21,28,35 or 42) or Visit 5 if not collected at Visit 4 (early termination or end of study, which occurred on Day 35,42,49 or 56) in Maintenance Phase
Primary	Number of Participants With All-causality and Treatment-related Adverse Events (AEs)	An AE was any untoward medical occurrence in a clinical investigation patient administered a product or medical device; the event needed not necessarily have a causal relationship with the treatment or usage. All-causality AEs refer to any AE occurrence which needed not necessarily have a causal relationship with the treatment or usage. Treatment-related AEs refer to AEs that have a causal relationship with the treatment or usage. The majority of AEs were of mild to moderate severity.	Baseline up to Day 63
Primary	Number of All-causality and Treatment-related AEs, by Intensity	An AE was any untoward medical occurrence in a clinical investigation patient administered a product or medical device; the event needed not necessarily have a causal relationship with the treatment or usage. All-causality AEs refer to any AE occurrence which needed not necessarily have a causal relationship with the treatment or usage. Treatment-related AEs refer to AEs that have a causal relationship with the treatment or usage. The majority of AEs were of mild to moderate severity.	Baseline up to Day 63
Primary	Number of Participants With All-causality and Treatment-related Serious Adverse Events (SAEs)	An SAE was any untoward medical occurrence at any dose that: resulted in death; was life-threatening (immediate risk of death); required inpatient hospitalization or prolongation of existing hospitalization; resulted in persistent or significant disability/incapacity (substantial disruption of the ability to conduct normal life functions); resulted in congenital anomaly/birth defect. All-causality SAEs refer to any SAE occurrence which needed not necessarily have a causal relationship with the treatment or usage. Treatment-related SAEs refer to SAEs that have a causal relationship with the treatment or usage.	Baseline up to Day 63
Primary	Number of Participants With Clinical Opiate Withdrawal Scale (COWS)	The COWS contains 11 common opiate withdrawal signs or symptoms rated by the clinician.The summed score of the 11 items is used to assess a subject's level of withdrawal. A subject assessed with a COWS score>= 13 was treated for opiate withdrawal signs and symptoms according to the investigator's medical judgment. The total COWS score ranges from 0 to 48. Higher scores indicate worse outcome. Different score ranges represent different severities of withdrawal: no withdrawal (<5), mild (5-12), moderate (13-24), moderately severe (25-36), and severe (>36)	Screening, Day 1, Titration Phase: Weeks 1,2,3,4; end of titration phase; Maintenance phase: Weeks 2, 4; early termination at titration phase, end of maintenance phase.
Secondary	Apparent Volume of Distribution (Vz/F) of Oxycodone	ALO-02 capsules consist of controlled-release pellets containing oxycodone hydrochloride (HCl) and naltrexone HCl. Oxycodone is a main component of this product.	Visit 4 (Day 21,28,35 or 42) or Visit 5 if not collected at Visit 4 (early termination or end of study, which occurred on Day 35,42,49 or 56) in Maintenance Phase
Secondary	Systemic Exposure Levels of the Metabolites of Oxycodone (Oxymorphone and Noroxycodone), Naltrexone, and 6-ß-naltrexol.	Oxymorphone and noroxycodone are major metabolites of Oxycodone and 6-ß-naltrexol is the major metabolite of naltrexol.	Visit 4 (Day 21,28,35 or 42) or Visit 5 if not collected at Visit 4 (early termination or end of study, which occurred on Day 35,42,49 or 56) in Maintenance Phase
Secondary	Number of Participants With Maximum Changes in Vital Signs (Blood Pressure, Heart Rate, Respiratory Rate) Meeting Categorical Summarization Criteria	Following parameters were analyzed for examinations of vital signs: resting systolic and diastolic blood pressure, heart rate, and respiratory rate. In this study, there were only participants meeting the maximum decrease from baseline in systolic blood pressure (SBP) >= 30 mmHg and diastolic blood pressure (DBP) >=20 mmHg criteria. None of the vital sign changes were clinically significant.	Baseline up to Day 58
Secondary	Number of Participants With Laboratory (Lab) Abnormalities (Hematology and Chemistry)	Following parameters were analyzed for hematologic laboratory tests: hemoglobin, hematocrit, red blood cells, mean corpuscular volume, platelets, white blood cells, lymphocytes (absolute & %), neutrophils (absolute & %), basophils (absolute & %), eosinophils (absolute &%), monocytes (absolute & %). Following parameters were analyzed for chemical laboratory tests: bilirubin,aspartate aminotransferase, alanine aminotransferase,alkaline phosphatase, protein(total), albumin,blood urea nitrogen, creatinine, cholesterol, sodium, potassium,chloride, calcium, phosphate, bicarbonate, glucose, creatine kinase.
