Constipation Clinical Trial
Official title:
A Confirmatory, Placebo-controlled, Randomised, Double-blind, Single-dummy, Parallel Group, Ratio-finding Study in Constipated Pain Patients to Establish an Optimal Hydromorphone - Naloxone Ratio With an Improved Bowel Function and a Comparable Analgesic Efficacy Compared to Hydromorphone Alone
The purpose of this study is to establish an optimal hydromorphone - naloxone ratio with an improved bowel function for constipated pain patients.
Subjects suffering from cancer or non-cancer pain suffering from constipation cased or aggravated by opioids will be randomised to one of four ratios of hydromorphone PR plus naloxone PR or Hydromorphone PR plus placebo to investigate whether a hydromorphone/naloxone combination will lead to comparable analgesia, with a decrease in constipation, and to investigate the optimal dose ratio of hydromorphone and naloxone. ;
Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double-Blind, Primary Purpose: Treatment
