Multicenter Study
Innovative pain therapy with a fixed combination of prolonged-release oxycodone/naloxone: a large observational study under conditions of daily practice.
Chronic pain has a marked negative impact on quality of life. Opioid treatment is often effective in controlling this pain, but it has numerous side-effects, particularly affecting bowel function. ⋯ This is a multi-center, prospective, non-interventional, observational study. Analgesic efficacy and bowel function were assessed in patients suffering from long-lasting, severe chronic pain of different etiology (cancer and non-cancer) treated with combined PR oxycodone/PR naloxone and observed for 4 weeks. Pain was evaluated using the Brief Pain Inventory (BPI-SF) and constipation symptoms due to opioid treatment using the Bowel Function Index (BFI). Descriptive data are presented based on observed cases, efficacy and tolerability data additionally based on completely documented patients (for each parameter at least more than 2000 patients).

Randomized Controlled Trial Multicenter Study Comparative Study
Once-daily OROS hydromorphone ER compared with placebo in opioid-tolerant patients with chronic low back pain.
This multicenter, double-blind, placebo-controlled study using a randomized withdrawal design evaluated the efficacy and safety of once-daily OROS hydromorphone ER in the treatment of opioid-tolerant patients with chronic moderate-to-severe low back pain (LBP). ⋯ These results provide evidence for the efficacy and safety of hydromorphone ER in opioid-tolerant patients with chronic moderate-to-severe LBP. Potential limitations include the shortened dose-conversion/titration phase, limiting the daily allowable dose of hydromorphone ER to 64 mg, and the allowance of limited rescue medication throughout the entire double-blind phase. Other trial design elements such as the use of an enrichment phase and the inclusion of only opioid tolerant patients may limit the generalizability of these results.

Randomized Controlled Trial Multicenter Study
A 26-week, placebo- and pioglitazone-controlled, dose-ranging study of rivoglitazone, a novel thiazolidinedione for the treatment of type 2 diabetes.
To examine the efficacy and general safety of rivoglitazone, a novel thiazolidinedione, as a treatment for type 2 diabetes in a dose-ranging study over a period of up to 6 months. ⋯ Rivoglitazone is a potent thiazolidinedione agent with demonstrated glycemic benefits over a 6-month period in subjects with type 2 diabetes. Once-daily doses of 1, 2, and 3 mg rivoglitazone demonstrated HbA(1c) reduction similar or superior to those observed for pioglitazone 45 mg. Limitations in generalizing from this study include a modest sample size and a high rate of discontinuation prior to the last scheduled visit.
