A Study to Evaluate Withdrawal Effects Following Dosing of Oxycodone/Naltrexone in Methadone-Maintained Subjects

Completed · Phase 3 · Has a placebo group

Conditions studied: Withdrawal Symptoms

In brief

This single-center study is a randomized, double-blind, active-controlled, multiple-dose, parallel group study to evaluate the potential withdrawal effects, safety and tolerability, and pharmacokinetic and pharmacodynamic effects of multiple doses of oral intact Oxycodone/Naltrexone capsules compared to oxycodone in methadone-maintained opioid-dependent subjects. The study will consist of a Screening Phase, an inpatient Treatment Phase (including a methadone stabilization period, a placebo administration period, a treatment administration period and a safety/washout period), and a Follow-up Phase.

• Body mass index (BMI) within the range of 18.0 to 35.0 kg/m2, inclusive, and a minimum weight of 50.0 kg.
• Maintained on a stable methadone regimen. Subjects must be receiving a methadone dose of 50 to 150 mg/day at Screening, with dosage variation ≤20% for at least 14 days prior to the Screening visit and who are willing to remain on their dose at Screening and for the duration of the study.
• The study volunteer has been previously exposed to opioids while on methadone maintenance without relapse occurring, or in the opinion of the methadone maintenance program Director or Physician, is not at undue risk of relapse from participation in the clinical study.

You may not qualify if…

• History or presence of clinically significant abnormality as assessed by physical examination, medical history, 12-lead ECG, vital signs, or laboratory values, which in the opinion of the investigator would jeopardize the safety of the subject or the validity of the study results.
• Clinically significant infection/injury/illness within 1 month prior to Screening.
• Has been diagnosed with cancer within 5 years prior to screening (excluding squamous or basal cell carcinoma of the skin), or has an active malignancy of any type (including squamous or basal cell carcinoma of the skin).
• History of major mental illness that in the opinion of the investigator may affect the ability of the subject to participate in the study. Institutionalized subjects will not be eligible for participation.
• Documented history of a medical condition that, in the opinion of the investigator, would compromise the subject's ability to swallow, absorb, metabolize, or excrete test product, including (but not limited to) intractable nausea and/or vomiting and/or severe gastrointestinal narrowing (pathologic or iatrogenic).
• Documented history of, or currently active, seizure disorder or history of clinically significant head injury or syncope of unknown origin.
• History of severe allergic reaction (including anaphylaxis) to any substance, or previous status asthmaticus, or food allergies/intolerances/restrictions, or special dietary needs which, in the judgment of the investigator, contraindicates the subject's participation in the study.
• History of allergy or hypersensitivity to oxycodone or related drugs (e.g., other opioids) or naltrexone or related drugs (e.g., other antagonists).
• 13. An employee of the sponsor or research site personnel directly affiliated with this study or their immediate family member defined as a spouse, parent, child or sibling, whether biological or legally adopted.
