Phase 2TerminatedNCT01001923

Regeneron Pharmaceuticals15 enrolled

Overview

Primary objective was to demonstrate the activity of REGN475/SAR164877 in reducing the pain associated with chronic pancreatitis. Secondary objectives were: * to assess the safety and tolerability of REGN475/SAR164877 in patients with chronic pancreatitis pain; * to characterize the pharmacokinetic, pharmacodynamic, and immunogenicity profiles of REGN475/SAR164877 in this population; * to measure the change in the total daily dose of rescue medications required.

The duration of the study period for each participant was up to 14 weeks, including a screening period up to 2 weeks, and 12-week follow-up after the injection.

Outcomes

Primary Outcomes

Mean change from baseline in pain intensity as assessed by Pain Intensity Numeric Rating Scale (PI-NRS)

The baseline value was defined as the average of PI-NRS values obtained at screening and at randomization visit. The Week 4 value was defined as the average of PI-NRS values obtained daily through e-Diary assessments during Week 4.

Time frame: baseline and 4 weeks after injection

Secondary Outcomes

Mean change from baseline in pain intensity as assessed by PI-NRS

Time frame: baseline and every other weeks up to 12 weeks after injection

Percentage of pain-free days (score "0" pain on PI-NRS)

Time frame: 12 weeks

Percentage of days with rescue analgesia use

Time frame: 12 weeks

Change from baseline in Short Form-12 Item Quality of Life Questionnaire [SF-12] score

Time frame: baseline and 4, 8, 12 weeks

Patient Global Impression of Change [PGIC] score

Time frame: 4, 8 and 12 weeks

Percentage of participants with at least 30% and 50% reduction from baseline in pain intensity

Time frame: up to 12 weeks after injection

Pharmacokinetic: REGN475/SAR164877 serum concentration

Time frame: 12 weeks
