Clinical Trial 4970

Seattle, WA 98104

Study Summary:

Stuttering can have a tremendous impact on a person's life: their social functioning, their occupational achievement. Investigators are seeking adults who stutter for a clinical research study to test whether pagoclone, an investigational medication for stuttering, may offer a way to achieve more fluent speech.

Approximately 300 adults who stutter enrolled to receive either pagoclone or a placebo.
This study will require six office visits and four telephone check-ins over an eight-month period.

At the end of the eight-month treatment period, participants may have an option to choose to continue an extension of the study in which all participants will receive pagoclone for approximately 12 months.
If the current study is successful, future investigations may combine study medication with speech therapy.

Qualified Participants Must:

• Be between the ages of 18 and 80
• Have a history of stuttering prior to age eight
• Be English-speaking with an eighth grade educational level

Qualified Participants May Receive:

Study-related visits, procedures and study medications provided at no cost. Participants may be compensated for travel-related expenses.
