Primary Outcome Measures:
  • Mean change in the dyskinesias rating scale (DRS) during "on" time [ Time Frame: Up to 104 weeks (from baseline 016 to EOS study 018) ] [ Designated as safety issue: No ]
    mean change in the dyskinesias rating scale (DRS) during "on" time from baseline (study 016) to endpoint (last visit in study 018).


Secondary Outcome Measures:
  • Endpoints include 'ON time', responder rates and UPDRS IV change [ Time Frame: Up to 104 weeks (from baseline 016 to EOS study 018) ] [ Designated as safety issue: No ]
    • Chge in ON time (ON+ON minor dysk),
    • Diary Resp Rate at 12-m, 18 & 24 m on the ITT&mITT pop&pts who completed 2-yr period
    • UPDRS IV chge in total score,items 32-35 & 32-34
    • Time develop tblsome dysk(> 30min incr of tblsome dysk)
    • Time develop any (minor &/or tblsome) dysk (> 30 min incr of dysk)
    • Chge ADLs during ON, vs pbo(UPDRS II)
    • Maintenance of effect in UPDRS II "resp'(resp >=20% impr in ADLs).

      • chge in L-dopa dose
      • chge in any PD(other than L-dopa)drug dose
    • Chge in UPDRS III, CGI-C and CGI-S
    • Chge in diary categories(ON, OFF, ON minor dysk, ON tblsome dysk, ASLEEP)
