The purpose of this research study is to find out the potential benefits and safety of asenapine (Saphris®) in adults who suffer from the developmental form of stuttering.
It is hypothesized that individuals who are randomly assigned to asenapine will have an improvement in speech as compared to a placebo.
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Treatment
||A Randomized, Placebo-Controlled Study to Evaluate the Efficacy and Tolerability of Asenapine With Flexible Dosing From 5mg to 20mg in Adults With Developmental Stuttering
Primary Outcome Measures:
Secondary Outcome Measures:
- Clinical Global Impression [ Time Frame: 2 minutes ] [ Designated as safety issue: No ]
This is an evaluation of the patient by the investigator as to whether or not the subjects has improved, remained the same, or worsened while in the study.
- Barnes Akathisia Scale [ Time Frame: 3 minutes ] [ Designated as safety issue: Yes ]
Measures how restless the subject is during the examination.

- Subjects must satisfy DSM-IV criteria for stuttering.
- The nature of stuttering must be developmental in origin with the onset prior to ten years of age.
- Subjects must have a score of moderate or higher on the SSI-IV. 4) Women of child-bearing potential are eligible to participate as long as they are practicing a medically accepted form of contraception (i.e. condom with spermicide or diaphragm, oral or depot contraception, or an intrauterine device).
5)Subjects will be male or female from the ages of 18-70. 6)Subjects will be of only English speaking.
Subjects will be excluded from the study for any of the following reasons:
- Stuttering related to a known neurologic cause (e.g. head trauma, stroke).
- Unstable medical or psychiatric illness.
- Active substance abuse within three months prior to study inclusion.
- Any illness that would require the concomitant use of a CNS active medication during the course of the study.
- Subjects with Parkinson's dementia or other degenerative neurologic illness.
- Subjects who are pregnant or nursing an infant.
