Orexo's Partner Endo Announces Positive Results from Interim Analysis of Rapinyl Phase III Clinical Trial
On the basis of these results and in accordance with the predetermined criteria of the interim analysis, Endo is terminating enrollment in the double-blind crossover portion of this clinical study. Enrollment is continuing in the safety portion of this trial and a second Phase III trial to meet the requirements for additional safety data. Rapinyl ™ is an oral, fast-dissolving tablet of fentanyl intended for the treatment of breakthrough cancer pain. Rapinyl ™ is in registration phase in Europe with Orexo's partner ProStrakan. Kyowa Hakko, a licensee in Japan, is preparing for a phase III study.
"We are extremely pleased by the outcome of this analysis, which we believe demonstrates that Rapinyl ™ can be an effective treatment for breakthrough pain in cancer patients," said David A. Lee, M.D., Ph.D., Chief Scientific Officer. "We remain confident that Rapinyl's quick dissolution and rapid absorption profile make it a potentially attractive treatment for breakthrough cancer pain."
Endo will conduct a thorough analysis of the data to determine the next course of action, including the possibility of filing a New Drug Application (NDA) based on these results.
Endo further noted that although this planned interim analysis was only intended to determine efficacy and not tolerability, those adverse events that were reported were consistent with what is usually observed with other opioids.
"The results from Endo Pharmaceuticals support that Rapinyl ™ can be an effective treatment for breakthrough pain in cancer patients," said Torbjorn Bjerke, M.D., President and CEO. "It is also a confirmation of our sublingual tablet form and how well it works when immediate onset of effect is desirable".
