CM4620 Injectable Emulsion Versus Supportive Care in Patients With Acute Pancreatitis and SIRS
An Open-Label, Dose-Response Study of CM4620 Injectable Emulsion (CM4620-IE) in Patients With Acute Pancreatitis and Accompanying Systemic Inflammatory Response Syndrome (SIRS)
This open-label, dose-response study will evaluate the safety and efficacy of CM4620-IE in patients with acute pancreatitis and accompanying SIRS. The study will consist of two phases. The first phase will consist of 4 female and 4 male patients (cohorts 1 and 2, respectively), enrolled concurrently, randomized in a 3:1 ratio to receive CM4620-IE plus standard of care versus standard of care alone. Planned doses for first phase will be CM4620-IE 1.0 mg/kg on Day 1 and then 1.4 mg/kg on Days 2 - 4.
The second phase will consist of 8 female and 8 male patients (cohorts 3 and 4, respectively), enrolled concurrently, randomized in a 3:1 ratio to receive CM4620-IE plus standard of care versus standard of care alone. Planned doses for second phase will be CM4620-IE 2.08 mg/kg on Days 1 and 2 and then 1.6 mg/kg on Days 3 and 4. Dose escalation to second phase would only occur if needed for efficacy reasons and if no events suggesting a safety signal would occur with higher dosing.
The study is not powered for the analysis of study data with inferential statisitcs as the primary purpose of the study is to explore what endpoints would be most appropriate for future trials.

Intervention / Treatment
Detailed Description
After review of the efficacy, tolerability and safety data from cohorts 1 and 2 by the sponsor and the United States Food and Drug Administration, the decision was made to continue the low-dose regimen (CM4620-IE 1.0 mg/kg on Day 1 and then 1.4 mg/kg on Days 2 - 4) in cohort 3. Cohort 4 received the high-dose regimen (CM4620-IE 2.08 mg/kg on Days 1 and 2 and then 1.6 mg/kg on Days 3 and 4) as planned. Efficacy analysis were combined because no dose escalation occurred in cohort 3.
Patients were followed for 90 days after randomization.

CTSI score measures abnormal pancreatic morphology and is the sum of two subscales.
The Balthazar subscale rates pancreatic CT image findings on a scale of 0 (normal) to 4 (2 or more peri-pancreatic fluid collections.
The Pancreatic Necrosis subscale rates pancreatic necrosis from 0 (none) to 6 (>50%).
The two subscales are summed for a CTSI score of 0-3 (mild AP), 4-6 (moderate AP), and 7-10 (severe AP).
