Overview
Brief Summary
This is a randomised, double-blind, two-stage, placebo controlled study. It is designed to investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of 3 doses of nangibotide versus placebo in adult patients with septic shock.
Detailed Description
This was a randomised, double-blind, two-stage, placebo-controlled study. It was composed of 2 stages with a similar treatment regimen in which 0.3, 1.0 or 3.0 mg/kg/h of nangibotide was tested versus placebo. Stage 1 was performed to investigate ascending doses of nangibotide or placebo in a sequential design in cohorts of 4 patients (3:1 randomisation). After completion of a cohort (for up to 5 days of infusion), safety and available PK data were blindly reviewed by an independent data safety monitoring board (DSMB) before progressing to the next cohort. After completion of stage 1 DSMB evaluation, the study progressed to stage 2. Stage 2 investigated 3 doses of nangibotide in a randomised, balanced, parallel-group design involving up to 3 doses of nangibotide and a placebo arm. Only dose arms of nangibotide considered to be safe and well tolerated during Stage 1 were to be administered in Stage 2.

Outcomes
Primary Outcomes
Number of Patients Experiencing Treatment Emergent Adverse Events From Screening Until Study Completion
Time Frame: Adverse events experienced until D28 (End of study visit)
Analyses were performed in the Safety Set composed of all randomized patients who received at least any dose of the study drug (nangibotide or placebo). Adverse events: Summary statistics of treatment emergent adverse events (TEAEs). Clinical events, including death, related to severe sepsis and sepsis complications were exempt from SAE reporting, unless the investigator deemed the event to be related to the administration of the study drug.
Systolic Blood Pressure (SBP)
Time Frame: Vital signs were assessed each day from day zero (D0 [before investigational medicinal product initiation]) to end of infusion at day 5 (D5) and on final study day at day 28 (D28).
Systolic blood pressure measured by sphygmomanometer at study site. Median SBP at each visit is summarized by treatment group.
Diastolic Blood Pressure (DBP)
Time Frame: Vital signs were assessed each day from day zero (D0 [before investigational medicinal product initiation]) to end of infusion at day 5 (D5) and on final study day at day 28 (D28).
Median DBP at each visit is summarized by treatment group.
Median Arterial Pressure (MAP)
Time Frame: Vital signs were assessed each day from day zero (D0 [before investigational medicinal product initiation]) to end of infusion at day 5 (D5) and on final study day at day 28 (D28).
MAP at each visit is summarized by treatment group.
Heart Rate
Time Frame: Vital signs were assessed each day from day zero (D0 [before investigational medicinal product initiation]) to end of infusion at day 5 (D5).
Median heart rate at each visit is summarized by treatment group.
Temperature
Time Frame: Vital signs were assessed each day from day zero (D0 [before investigational medicinal product initiation]) to end of infusion at day 5 (D5).
Median temperature at each visit is summarized by treatment group.
Electrocardiogram
Time Frame: Electrocardiogram was performed each day from D0 (before IMP initiation) to D5 (EOI) and on D28 (EOS).
Abnormal and emergent clinically significant electrocardiogram were summarized for each group.
Anti-Drug Antibodies (ADA Dimer)
Time Frame: Anti-Drug Antibodies test were done at D0, D10 and D28 in all patients.
Anti-Drug Antibodies test was performed for all patients.
Anti-Drug Antibodies (ADA Monomer)
Time Frame: Anti-Drug Antibodies test were measured at D0, D10 and D28.
Anti-Drug Antibodies test was performed for all patients.
