    Arm Description

    We will enroll up to 36 Participants; each is receiving repeated unit doses of DNase I, BID, delivered by IV infusion over 3 or 7 consecutive days (12 +/- 1 hour apart) according to the following dose-escalation schedule with up to 6 Participants per dose panel. Panel 1: 25 µg/kg, BID for 3 days (cumulative dose: 150 µg/kg) Panel 2: 25 µg/kg, BID for 7 days (cumulative dose: 350 µg/kg) Panel 3: 125 µg/kg, BID for 3 days (cumulative dose: 750 µg/kg) Panel 4: 125 µg/kg, BID for 7 days (cumulative dose: 1750 µg/kg)

    We will also enroll 12 septic Participants who do not receive intravenous DNase I (as Comparator Group). These patients will be recruited contemporaneously based on the same inclusion and exclusion criteria.

    5. Study Description

    Brief Summary
    Phase I dose-escalation safety and feasibility of IV DNase I in ICU septic patients.
    Detailed Description
    In sepsis, the release of 'neutrophil extracellular traps' (NETs) by activated neutrophils may contribute to organ damage by acting as scaffolds that trap blood cells and fibrin clots. Excessive NET formation can occlude the vasculature, promoting thrombosis and tissue hypoperfusion. This is a trial on a novel IV therapy for septic patients that shows promise in multiple animal models of sepsis. The therapy, DNase I, is an enzyme that helps to dismantle NETs by digesting cell-free DNA (cfDNA), the major structural component of NETs. The objective of this study is to conduct a Phase I dose-escalation safety and feasibility of IV DNase I in ICU septic patients. The results of this study may justify a future Phase II trial of the efficacy and safety of DNase I for critically ill patients with sepsis. This trial proposes - To determine the safety, feasibility and maximum tolerated dose (MTD) of using DNase I in septic patients - To evaluate clinical endpoints common in the critically ill such as organ dysfunction severity and trajectory, ICU length of stay, and mortality. - To describe the effects of DNase I on blood coagulation and NETs release - To collect samples for future studies on coagulation and immune function in sepsis.
