This article discusses ethical challenges encountered in the design of an effectiveness trial (CTN-0051, X:BOT), comparing sublingual buprenorphine-naloxone (BUP-NX), an established treatment for opioid dependence, to the newer extended-release injectable naltrexone (XR-NTX). Ethical issues surrounded:

  1. Known poor effectiveness of one possible, commonly used Treatment as Usual control condition -- detoxification followed by counseling without medication;
  2. The role of patients' preferences for treatments, given that treatments were clinically approved and available to the population;
  3. Differences between the optimal "usual treatment" clinical settings for different treatments making it challenging to design a fair comparison;
  4. Vested interest groups favoring different treatments exerting potential influence on the design process;
  5. Potentially vulnerable populations of substance users and prisoners;
  6. Potential therapeutic misconception in the implementation of safety procedures; and
  7. High cost of a large trial limited questions that could be addressed.

The authors examine how the design features underlying these ethical issues are characteristic of effectiveness trials, which are often large trials that compare treatments with varying degrees of existing effectiveness data and familiarity to patients and clinicians, in community-based treatment settings, with minimal exclusion criteria that could involve vulnerable populations. Hence, investigators designing effectiveness trials may wish to remain alert to the possibility of similar ethical issues. (Article (Peer-Reviewed), PDF, English, 2016)
