Study Description

The trial enrolls patients with early severe sepsis or septic shock displaying at least one newly developed organ dysfunction and showing clinical evidence of pulmonary or abdominal infection. The primary goal of the trial is to assess the pharmacokinetics and pharmacodynamics of the new monoclonal antibody CaCP29 and to characterize safety and tolerability as well as evaluate parameters of efficacy.

3. Morbidity [ Time Frame: daily ]
   • Mean SOFA until Day 10
   • Modified mean SOFA until day 10 (calculated by omitting the Central Nervous System sub-score and calculating the renal subscore without taking urine output into consideration)
   • Mean SOFA Sub-scores until Day 10
   • Days on ICU until Day 28
   • Number of patients ventilated until Day 14
   • Ventilator-free days until Day 14
   • Numbers of patients with renal replacement therapy (RRT) until Day 14
   • RRT-free days until Day 14
   • Numbers of patients with administration of vasopressor until Day 14
   • Vasopressor-free days until Day 14
   • Days without antimicrobial therapy (AMT) until Day 14
4. Fluid balance [ Time Frame: 28 days or ICU discharge ]
   • Mean daily total fluid intake until Day 28 (maximal until ICU discharge)
   • Mean daily total fluid output until Day 28 (maximal until ICU discharge)
   • Mean daily fluid balance until Day 28 (maximal until ICU discharge)
5. Change in routine laboratory parameters as compared to baseline [ Time Frame: Days 1, 2, 3, 4, 5, 8, 13, 28 ]
6. Change in ECG as compared to baseline [ Time Frame: Days 2, 4, 8, 28 ]
7. Change in vital signs as compared to baseline [ Time Frame: Days 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, Day 28 ]

Eligibility Criteria

Criteria

Key Inclusion Criteria at screening:

1. Male or female patients >= 18 years old
2. Written informed consent

4. Suspected or confirmed abdominal or pulmonary infection at screening
5. Broad spectrum i.v. antimicrobial therapy to treat abdominal or pulmonary infection

6. At least one of the following acute organ dysfunctions due to sepsis. Each organ dysfunction must have occurred within 12 hours prior to screening, cannot mainly be explained by other disease processes than sepsis and is judged by the investigator as being caused or directly related to an abdominal or pulmonary infectious focus:

   1. respiratory
   2. renal
   3. hematologic
   4. metabolic
   5. cardiovascular (occurred within the last three hours)
