E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Severe acute pancreatitis in man (with an APACHE II score of ≥ 15) appears to carry a considerably higher risk of death when compared to general critical care patients with similar APACHE II scores. Current concepts of the pathophysiology of pancreatic necrosis suggest that disease progression is related to early activation of microvascular thrombotic pathways thus a theoretical case can be made for the use of activated protein C, early in the disease course of this illness |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to undertake a preliminary evaluation of the role of human recombinant activated protein C administered early in the disease course of human severe acute pancreatitis. The principal end-points are assessment of safety of treatment and assessment of effect of intervention on markers of the coagulation and inflammatory response.

|
E.2.2 | Secondary objectives of the trial |
Interim analysis may indicate the feasibility or otherwise of a preliminary health economic analysis. Given that clinical experience with the use of xigris in severe acute pancreatitis is extremely limited, the proposed study will provided valuable baseline information that will help in two key areas: defining the nature of the acute pancreatitis population who may benefit from treatment with xigris and assessing the risk-benefit balance of intervention with xigris. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Acute pancreatitis – defined as acute abdominal pain with a threefold elevation of serum amylase or a twofold elevation of serum lipase. 2.

Patients with a prior history of bleeding duodenal ulcer, haemorrhagic stroke or other haemorrhagic diathesis. 6. Patients taking warfarin or other anticoagulant medication. Thrombocytopenia, coagulopathy. 7. Patients with evidence of end-stage renal disease. Patients with liver disease. 8. Under 18 years of age. 9. Surgery or ERCP within the previous 30 days. 10.

E.5 End points |
E.5.1 | Primary end point(s) |
Primary endpoints The primary objective of this study is to undertake a preliminary evaluation of the role of human recombinant activated protein C administered early in the disease course of human severe acute pancreatitis. The principal end-points are assessment of safety of treatment and assessment of effect of intervention on specific markers of coagulation, in particular the Protein C response.
Primary endpoint - clinical adverse event assessment 1. All bleeding events 2. Serious bleeding events. These are defined as per the PROWESS trial criteria as follows: any intracranial haemorrhage, any life-threatening bleed, any bleeding event requiring the administration of ≥ 3 units of packed red blood cells per day for 2 consecutive days or any bleeding event assessed as a serious adverse event. 3. Thrombotic events – Any events observed (and recorded by the patients’ clinicians) will be noted. Any serious adverse events will be reported to the Eli Lilly pharmaco-vigilance division within 24 hours together with a causality assessment.
Primary endpoint – Coagulation & Inflammatory Biomarkers
Based on preliminary information discussed during the course of a meeting held during the 20th annual congress of the European Society of Intensive Care Medicine it appears that levels of protein C may be an important indicator of response to treatment with activated protein C (21) and that further, protein C levels may be indicators of consumptive coagulopathy in severe acute pancreatitis. In this study, protein C levels will be measured at baseline (prior to commencement of infusion) and at 24 hours upon completion of the Xigris infusion. Further measurements of protein C will be undertaken at 48 hours, 72 hours, 1 week and day 10. A baseline haematological profile (including full blood count and haematocrit) and clotting profile including PT, APTT and bleeding time will be recorded at baseline, after infusion and daily during the first week (in keeping with good clinical practice). Baseline evidence of pancreatic haemorrhage will be assessed by intravenous contrast-enhanced computed tomography prior to commencement of infusion. CT will be repeated 48 hours after completion of infusion.
