Study summary

This study is aimed to demonstrate equivalence between combinations of lower strength OXN PR tablets (OXN PR LST) and single higher strength OXN PR tablets (OXN PR HST) taken at the same overall daily dose.

Read the detailed description

Study OXN3508 is a multicenter double-blind, double-dummy, randomised, cross-over, 2-period, phase III study in male and female subjects with severe non-malignant or malignant pain that requires around-the-clock opioid therapy at a daily dose of 120/60 mg or 160/80 mg oxycodone/naloxone prolonged release (OXN PR).

What researchers measure

Primary outcomes

  1. (mean of subjects average pain over the last 24 hours as assessed by the pain intensity scale.)

    Pain scores based on the mean of subjects average pain over the last 24 hours as assessed by the pain intensity scale. To demonstrate equivalence between multiple lower strength OXN PR tablets and a single higher strength OXN PR tablet taken at the same overall total daily dose

    Time frame: 24 hours at one day in week 2, 3 5 and 6 from date of randomisation.

  2. Equivalent bowel function as assessed by the Bowel Function Index (BFI).

    Time frame: Week 2, 3 5 and 6 from date of randomisation.

Secondary outcomes

  1. Pain scores of subjects average pain over the last 24 hours and rescue medication use.

    Time frame: Week 1,2,3,4,5 and 6 from date of randomisation

  2. To assess bowel function (assess BFI and laxative use)

    To assess BFI and laxative use

    Time frame: Week 1,2,3,4,5 and 6 from date of randomisation

  3. To assess quality of life based on the EuroQol EQ-5D.

    EuroQol EQ-5D is a standardized instrument for use as a measure of health outcome.

    Time frame: Visit 3 and visit 6 from date of randomisation

  4. Number of participants with adverse events, high/low laboratory values and clinically significant ECG findings.

    Time frame: Up to 35 weeks

  5. Pain right now scores at intake of oxycodone/naloxone tablets.

    Time frame: Week 2,3,5 and 6 from date of randomisation
