About the study

This is a phase I/II clinical trial assessing the tolerability and efficacy of CM4620 in children and young adults with acute pancreatitis caused by asparaginase. The tolerability of CM4620 when given to patients receiving frontline chemotherapy will be determined. The effectiveness in reducing the severity of pancreatitis will be estimated.

Primary Objectives

To assess the safety of CM4620 administration in children and young adults with asparaginase associated pancreatitis (AAP).

To profile dose-limiting toxicities and responses of the patients treated in the dose-finding phase.

To estimate the efficacy of CM4620 to prevent pseudocyst or necrotizing pancreatitis in children with AAP.

Secondary Objectives

To determine the effect of CM4620 on the incidence of severe pancreatitis

To determine the effect of CM4620 on the incidence of Systemic Inflammatory Response Syndrome (SIRS).
