| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of the trial is the evaluation of the safety profile of CG5503 PR base at doses ranging between 100 mg and 250 mg BID over long term exposure of up to one year.;Secondary Objective: • Assessment of CG5503 PR and oxycodone CR dose requirements during long-term exposure. • Evaluation of symptoms related to constipation using the Patient’s Assessment of Constipation Symptom (PAC-SYM). • Evaluation of sleep quality by using Sleep Questionnaire (SQ). • Evaluation for symptoms of withdrawal following discontinuation of treatment using both the Clinical Opiate Withdrawal Scale (COWS) and the Subjective Opiate Withdrawal Scale (SOWS) questionnaires. • Assessment of pain intensity efficacy over the one-year trial period, based on pain intensity scores using an 11-point numerical rating scale (NRS). • Assessment of efficacy based on the subject’s and Investigator’s global assessment of the IMP. • Assessment of efficacy based on Patient’s Global Impression of Change (PGIC) using a 7-point verbal rating scale. • Assessment of quality of life based on EuroQuol-5 Dimension (EQ-5D). • Assessment of quality of life based on Short Form-36 Health Survey (SF-36®);Primary end point(s): No formal statistical testing will be performed in this study. The enrollment will target a minimum exposure of approximately 300 subjects to CG5503 PR for approximately 6 months and approximately 100 subjects for approximately one year. | — |
