Addictions are common, debilitating and costly disorders. Addictive disorders are chronic conditions characterized by compulsive use despite medical and psychological consequences of addiction. Interrupting drug use is associated with withdrawal and craving which are alleviated by using the drug again.

Multiple medications have been studied for the treatment of addictions but only few have been shown to be efficacious in well-controlled studies. Medications that have been approved by FDA target opioid, alcohol and nicotine addiction while no approved medications are available for cocaine or benzodiazepine addiction. Only fraction of patients receive medication assisted therapies even when an approved medication is available for treatment.

Developing new medications for addictions has many challenges. For cocaine and benzodiazepine dependence, regulatory authorities have not yet provided guidance as to what level of reduction in use constitutes clinically meaningful change, or whether the trials should be designed to test whether a complete abstinence can be achieved. From a clinical trial conduct perspective, one challenge is patient compliance during the trial. In a recent trial for cocaine dependence, only 40-60% of patients were estimated to be compliant with the study medication (Somoza et al JAMA Psychiatry 70: 630-637, 2013). Frequent engagement with patients and electronic patient reminders may be ways to enhance compliance and subject retention. Another challenge from operational perspective is to ensure that clinical trial end-points which rely on patient recollection of use, such as the time-line followback, are collected uniformly across the investigative sites. For these types of end-points, training and certification of the principal investigators is very important.

Dr. Lappalainen will present an overview of what medications have been developed for addictive disorder, what study end-points were used, and what operational challenges companies may face when developing medications for addictive disorders.
