• Pfizer Inc., of New York, disclosed top-line Phase III data from an open-label long-term safety study of ALO-02 (oxycodone hydrochloride and naltrexone hydrochloride extended-release capsules) in patients with moderate-to-severe chronic, noncancer pain. The primary objective of the study was to evaluate the safety of ALO-02 administered for up to 12 months. The study showed that the adverse event profile was as expected based on similar long-term safety studies with other extended-release opioid formulations, with the most common adverse events being nausea, constipation, vomiting and headache.
