简要总结
This study evaluated the efficacy, safety, pharmacokinetics, and pharmacodynamics of ravulizumab administered in adult participants with coronavirus disease 2019 (COVID-19) severe pneumonia, acute lung injury, or acute respiratory distress syndrome. Participants were randomly assigned to receive ravulizumab in addition to best supportive care (BSC) (2/3 of the participants) or BSC alone (1/3 of the participants). BSC consisted of medical treatment and/or medical interventions per routine hospital practice.

入选标准
- •Males or female participants ≥ 18 years of age and ≥ 40 kilograms at the time of providing informed consent.
- •Confirmed diagnosis of severe acute respiratory syndrome coronavirus 2 infection (for example, via polymerase chain reaction and/or antibody test) presenting as severe COVID-19 requiring hospitalization.
- •Severe pneumonia, acute lung injury, or acute respiratory distress syndrome confirmed by computed tomography or X-ray at Screening or within the 3 days prior to Screening, as part of the participant's routine clinical care.
- •Respiratory distress requiring mechanical ventilation, which can be either invasive (requiring endotracheal intubation) or noninvasive (with continuous positive airway pressure or bilevel positive airway pressure).
- •Female participants of childbearing potential and male participants with female partners of childbearing potential must follow protocol specified contraception guidance for avoiding pregnancy for 8 months after treatment with the study drug.
排除标准
- •Participant was not expected to survive for more than 24 hours.
- •Participant was on invasive mechanical ventilation with intubation for more than 48 hours prior to Screening.
- •Severe pre-existing cardiac disease (that is, New York Heart Association Class 3 or Class 4, acute coronary syndrome or persistent ventricular tachyarrhythmias).
- •Participant had an unresolved Neisseria meningitidis infection.
- •Used the following medications and therapies:
- •Current treatment with a complement inhibitor or
- •Intravenous immunoglobulin within 4 weeks prior to randomization on Day 1
- •Treatment with investigational therapy in a clinical study within 30 days before randomization, or within 5 half-lives of that investigational therapy, whichever was greater. Exceptions:
- •Investigational therapies were allowed if received as part of BSC through an expanded access protocol or emergency approval for the treatment of COVID-
- •Investigational antiviral therapies (such as remdesivir) were allowed even if received as part of a clinical study.
- •Female participants who were breastfeeding or who have a positive pregnancy test result at Screening.
- •History of hypersensitivity to any ingredient contained in the study drug, including hypersensitivity to murine proteins.
- •Participant who was not currently vaccinated against Neisseria meningitidis, unless the participant agrees to receive prophylactic treatment with appropriate antibiotics for at least 8 months after the last infusion of study drug or until at least 2 weeks after the participant receives vaccination against Neisseria meningitidis.
结局指标
主要结局
Survival (Based On All-Cause Mortality) in Participants in the ITT Population At Day 29
时间窗: Day 29
Survival (based on all-cause mortality) in Participants in the ITT Population at Day 29 was analyzed. The result for the survival was estimated survival combined over all imputations.
次要结局
- Number Of Days Free Of Mechanical Ventilation At Day 29(Day 29)
- Change From Baseline In Peripheral Capillary Oxygen Saturation/Fraction Of Inspired Oxygen (SpO2/FiO2) At Day 29(Baseline, Day 29)
- Number of Days the Participants Were Alive and Not in the Hospital(Day 1 through Day 29)
- Estimated Number of Participants Alive At Up To Day 60 and At Up To Day 90(Up to Day 60 and Up to Day 90)
- Number of Days the Participants Were Alive and Not in ICU(Day 1 through Day 29)
- Change From Baseline In Sequential Organ Failure Assessment (SOFA) At Day 29(Baseline, Day 29)
- Serum Ravulizumab Concentrations Prior to Dosing on Day 1 and Day 29(Day 1 and Day 29)
- Change From Baseline In Terminal Complement Complex C5b-9 At Day 29(Baseline, Day 29)
- Change From Baseline In Serum Free Complement Component 5 Concentrations At Day 29(Baseline, Day 29)
