1. Able to comprehend and willing to sign an informed consent form.
2. Male and female subjects between 30 and 83 years old, inclusive.
3. Diagnosed with idiopathic PD according to the UK Parkinsons Disease Society Brain Bank Clinical Diagnostic Criteria (UKPDSBBCDC) for at least 3 years.
4. Disease severity Stages I-III (modified Hoehn &Yahr staging) at ON.
5. Treated with L-DOPA/DDCI for at least 1 year with clear clinical improvement.
6. Treated with 3 to 8 daily doses of L-DOPA/DDCI, which can include a slow-release formulation.
7. On a stable regimen of L-DOPA/DDCI and other anti-PD drugs for at least 4 weeks before screening.
8. Signs of wearing-off phenomenon (end-of-dose deterioration) for a minimum of 4 weeks before screening with average total daily OFF time while awake of at least 1.5 hours, excluding the early morning pre-first dose OFF, despite optimal anti-PD therapy (based on the investigators judgment.
1. Non-idiopathic PD (atypical parkinsonism, secondary [acquired or symptomatic] parkinsonism, Parkinson-plus syndrome).

3. Severe and/or unpredictable OFF periods.
4. Treatment with prohibited medication: entacapone, tolcapone, neuroleptics, venlafaxine, MAO inhibitors (except selegiline up to 10 mg/day in oral formulation or 1.25 mg/day in buccal absorption formulation or rasagiline up to 1mg/day), or antiemetics with antidopaminergic action (except domperidone) within the month before screening.
5. Treatment with apomorphine within the month before screening or likely to be needed at any time during the study.

8. Previous stereotactic surgery (e.g. pallidotomy, thalamotomy) for PD or with planned stereotactic surgery during the study period.
9. Any investigational medicinal product (IMP) within the 3 months (or within 5 half-lives, whichever is longer) before screening.
10. Any medical condition that might place the subject at increased risk or interfere with assessments.

- Primary Outcome Measures
Name Time Method To investigate the efficacy of 2 different doses of BIA 9-1067 (25 mg and 50 mg), administered once a day, compared with placebo, when administered with the existing treatment of L-DOPA plus a DDCI, in patients with PD and end-of-dose motor fluctuations <br/ ><br> <br/ ><br>The primary efficacy variable will be the change from baseline in absolute OFF-time at the end of the DB period.Timepoint: 14-15 weeks
