PG - 423-36 LID - jom.2014.0239 [pii] LID - 10.5055/jom.2014.0239 [doi] AB - OBJECTIVE: To evaluate the long-term safety of oxycodone-hydrochloride and sequestered naltrexone-hydrochloride (ALO-02) administered for up to 12 months. DESIGN: Open-label, single-arm safety study. SETTING: Thirty-two US research centers (ClinicalTrials.gov identifier NCT01428583). PATIENTS: Three hundred ninety-five adults (opioid experienced and opioid naive) with moderate-to-severe chronic noncancer pain (CNCP). INTERVENTIONS: Open-label, oral ALO-02 capsules, daily dose ranging from 20 to 160 mg oxycodone for up to 12 months. MAIN OUTCOME MEASURES: Number and type of adverse events (AEs) and drugrelated AEs, including assessments of withdrawal (Clinical Opiate Withdrawal Scale; COWS), pharmacokinetics, efficacy, and aberrant behaviors (Current Opioid Misuse Measure). RESULTS: A total of 193 (48.9 percent) patients received ALO-02 for >/=181 days and 105 (26.6 percent) patients for >/=361 days. The most common treatment-emergent AEs were nausea (25.3 percent), constipation (21.3 percent), vomiting (13.9 percent), and headache (11.6 percent). The most common drug-related AEs were constipation (18.0 percent), nausea (14.9 percent), somnolence (8.4 percent), fatigue (6.8 percent), dizziness (5.6 percent), and vomiting (5.1 percent). A majority of patients (86.6 percent) had a maximum COWS total score below the level for mild withdrawal symptoms at every visit throughout the study. Pain severity scores as measured by the short Form of the Brief Pain Inventory (BPI-SF) decreased over time. CONCLUSIONS: Repeat dosing of ALO-02 for up to 12 months is safe and well tolerated in a CNCP population of both opioid-experienced and opioid-naive patients. ALO-02 demonstrated a safety profile consistent with extended-release opioids and the expected analgesic efficacy. The addition of sequestered naltrexone had no significant clinical effect on patients when taken as directed. FAU - Arora, Samir AU - Arora S AD - Columbus Clinical Research, Columbus, Ohio.
