简要总结
This study is a Phase II open-label study to investigate the recommended conversion ratio (oral morphine dose to KW-2246) when switching oral morphine or oxycodone to KW-2246 in cancer patients.
详细描述
This study is a Phase II open-label study to investigate, using the continual reassessment method procedure by pain intensity and safety as indicators, the recommended conversion ratio (oral morphine dose to KW-2246) when switching oral morphine or oxycodone to KW-2246 in cancer patients who have been maintained on oral morphine or oral oxycodone for pain and to evaluate the safety and efficacy of KW-2246.
