- •3. Ability and willingness to comply with study treatment regimen and to attend study assessments;
- •4. Diagnosed with Tourette’s Disorder as per the below DSM-IV criteria and with a score =22 on the Total Tic Score (TTS) of the YGTSS at baseline:
- •Both multiple motor and one or more vocal tics have been present at some time during the illness, although not necessarily concurrently. (A tic is a sudden, rapid, recurrent, non-rhythmic, stereotyped motor movement or vocalization.)
- •The tics occur many times a day (usually in bouts) nearly every day or intermittently throughout a period of more than 1 year, and during this period there was never a tic-free period of more than 3 consecutive months
- •The onset is before age 18 years
- •The disturbance is not due to the direct physiological effects of a substance (e.g., stimulants) or a general medical condition (e.g., Huntington’s disease or post-viral encephalitis)
- •The disturbance causes marked distress or significant impairment in social, occupational, or other important areas of functioning
- •5. Diagnosis of Tourette’s Disorder when administering the Diagnostic Interview Schedule for Children (DISC-IV);
- •6. Women of childbearing potential must have a negative serum Beta-HCG pregnancy test at the Screening (Baseline) visit unless surgically sterile;
- •7. Either a de novo patient (not on current treatment for TS), or a patient who has been diagnosed with TS, but who the investigator feels, has not been adequately managed using current therapy, or has failed current therapy, whereby the patient may benefit in the use of pramipexole and, if on current therapy, can be safely discontinued from such therapy prior to enrollment into this study;
- •8. Women of childbearing potential must be using a medically accepted contraceptive method. Acceptable methods of birth control are limited to: Intra-Uterine Device (IUD), oral, implantable, injectable contraceptives and estrogen patch, double barrier
- •method (spermacide + diaphragm), or abstinence at the discretion of the investigator;

- •1. Any women of childbearing potential having a positive serum pregnancy test at screening;
- •2. Clinically significant renal disease or serum creatinine out of this range: 0.3-1.0 mg/dL for patients aged 6-12 years and 0.5-1.4 mg/dL for patients aged 13+ years;
- •3. Any of the following lab results at screening:
- •? Hemoglobin (Hgb) below lower limit of normal (LLN) which is determined to be clinically significant.
- •? Basal thyroid stimulating hormone (TSH), triiodothyronine (T3) or thyroxine (T4) clinically significantly (at the investigator’s discretion) out of normal range at screening (if not caused by substitution therapy according the investigator’s opinion).
- •? Patients with any clinically significant abnormalities in laboratory parameters at screening at the investigator’s discretion.
- •4. Other clinically significant metabolic-endocrine, hematological, gastrointestinal disease, pulmonary disease (such as severe asthma) in the opinion of the investigator which would preclude the patient from participating in this study;
- •5. History of schizophrenia or any psychotic disorder, history of mental disorders or any present Axis I psychiatric disorder according DSM IV (using the DISC-IV assessment interview) requiring any medical therapy except for TS, except for patients with a diagnosis of ADHD or OCD who are not on therapy;

- •7. History of/or clinical signs of any malignant neoplasm including suspicious undiagnosed skin lesion (which may be melanoma), melanoma, or a history of melanoma;

- •9. Allergic response to pramipexole or the inactive ingredients in its tablet formulation;
- •10. Had previous treatment with dopamine agonists other than pramipexole within 14 days prior to baseline visit;
