During the double-blind phase, participants were randomized
to OXN PR or OxyPR for 4 weeks (≤120 mg/day). During the
OLE, all patients receivedOXNPR every 12 h for ≤24 weeks).
Study Visit 9a (Day 1) was the first visit of the OLE phase of
the study and typically occurred on the same day as Visit 9
(end of the double-blind phase) (Figure 1A).
The initial starting dose was the effective analgesic dose
based on oxycodone or OXN PR that the patient was on at the
end of the double-blind phase. Any patient on a dose of
≤80 mg/day OxyPR was switched directly to OXN PR. For
example, all patients on 80mg/day OxyPR started with a daily
dose of OXN PR 80/40 mg. Those patients on >80 mg/day
OxyPR were switched to OXN PR in a stepwise manner. All
patients receiving 90, 100, 110, or 120 mg/day OxyPR were
started on OXN PR 40/20 mg 12 hourly with the remainder of
their oxycodone dose given as OxyPR. Dose titration was
permitted at the discretion of the investigator to ≤120/60 mg/
day. A total of 19 patients received OXN PR at a daily dose of
>80/40 mg; safety findings for these patients were no different
from the whole population.
Rescue medications (Oxy IR 5 mg and laxative bisacodyl
5 mg) were supplied for the first 7 days of the study. After
7 days, laxative use was documented as concomitant
medication.
