Study information
Scientific title
Acronym
Anticipate Trial
Study hypothesis
This study is designed to test the principal hypothesis that anti-oxidant therapy with ANTOX version 1.2 reduces pain in patients with painful chronic pancreatitis.
Ethics approval
Approval will be submitted to the Local Ethical Committee (North West MREC) on the 13th February 2007 (Project No. 07/MRE08/13).
Study design
The study will take the form of a double-blind, placebo-controlled, multi-centre randomised trial of ANTOX version 1.2 in patients with painful chronic pancreatitis.

Condition
Chronic pancreatitis
Intervention
We would be using intravenous blood sample for routine clinical Haematology/Bio-chemistry. Total dose of the treatment is two tablets three times a day for six months. Each tablet will be weighing 1145 mg (both Antox and placebo).
1. Pathological test: routine haematology and biochemistry
2. Face to face interview: with subjects enrolling in the trial
Intervention type
Drug
Phase
Not Specified
Drug names
Anti-oxidant therapy (ANTOX version 1.2)
Primary outcome measures
Each patient enrolled in the study will contribute pain scores at baseline and six months from which a change in pain score will be calculated. The primary endpoint will be the difference in change scores between treatment and control groups. The use of change rather than endpoint scores is important given the likely considerable interpersonal variation in the use of pain scales and thus removes interpersonal variance.
Secondary outcome measures
1. Time in pain assessed as the area under the curve of pain scores assessed at baseline, two, four and six months
2. Quality of life scores compared at enrolment to those at two, four and six months using disease specific measure (EORTC-QLQC30 and QLQ-PAN26) and a generic measure (EuroQOL EQ-5D)
3. Opiate usage (defined as morphine equivalents) assessed monthly over the six-month period of the study and analysed using repeated measures design
4. Incidence of specific pancreatitis-related complications: hospital admission with acute exacerbation of chronic pancreatitis or for pain control (defined from hospital discharge notes) and specific pancreatitis-related complications (pancreatic pseudocyst defined according to Atlanta consensus conference criteria) and pancreatic abscess
5. Economic analysis including use of anti-oxidant therapy and hospital-based resource utilisation associated with chronic pancreatitis
6. Assessment of any treatment-related side effects and complications
