The purpose of this study is find out if a new investigational botulinum toxin for injection is safe in adults with isolated cervical dystonia (CD) and if the effects last longer than the standard toxin treatment. Participants will receive a single injection of study medication, receive routine laboratory and study safety assessments and be compensated for travel. It is anticipated that 36 subjects will enroll at up to 8 study centers; up to 6 subjects are expected to enroll at Rush University Medical Center. Participation will last about 26 week. Subjects will be asked to come to the study center up to 11 times during the study and will be contacted by telephone to answer study-specific, health-related questions up to 3 times during the study.
