Lanadelumab in Participants Hospitalized With COVID-19 Pneumonia
Study Details
Study Description
Brief Summary
The purpose of this study is to evaluate the safety, pharmacokinetic and pharmacodynamics of lanadelumab administered by intravenous (IV) infusion when added to standard-of-care (SoC) in adults hospitalized with COVID-19 pneumonia.

Phase 1 |
Detailed Description
This study consists of two cohorts (Cohort 1 [Single-dose Cohort], and Cohort 2 [Repeat-dose Cohort]). Up to approximately 24 participants will be enrolled in this study, in which up to 12 participants may be enrolled into Cohort 1. However, Cohort 1 will be closed upon implementation of Amendment 2. Approximately 12 participants will be enrolled in Cohort 2. Participants will be randomized in 3:1 ratio (9 lanadelumab: 3 placebo) in each Cohort.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Lanadelumab Participants receive 300 milligram (mg) of lanadelumab intravenous (IV) infusion on Day 1 during Cohort 1 (single dose cohort) and on Day 1 and Day 4 during Cohort 2 (repeat-dose cohort). |
Drug: Lanadelumab
Participants will receive 300 mg of lanadelumab IV infusion on Day 1 and Day 4.
Other Names:
|
| Placebo Comparator: Placebo Participants will receive placebo matching IV infusion on Day 1 during Cohort 1 (single dose cohort) and on Day 1 and Day 4 during Cohort 2 (repeat-dose cohort). |
Other: Placebo
Participants will receive placebo matching IV infusion on Day 1 and Day 4.

Outcome Measures
Primary Outcome Measures
- Number of Participants with Treatment emergent adverse events (TEAEs) [From start of study drug administration to follow-up (up to Day 29)]
Treatment-emergent adverse events are defined as Adverse events (AEs) with onset at the time of or following the start of treatment with study medication, or medical conditions present prior to the start of treatment but increasing in severity or relationship at the time of or following the start of treatment. SAE is any untoward clinical manifestation of signs, symptoms or outcomes (whether considered related to investigational product or not and at any dose: results in death, is lifethreatening, requires inpatient hospitalization or prolongation of hospitalization, results in persistent or significant disability/incapacity, congenital abnormality/birth defect, an important medical event. AESI will include hypersensitivity reactions, events of disordered coagulation such as bleeding AESI, hypercoagulable AESI. Number of participants with TEAEs including AESI and SAE will be assessed.
Secondary Outcome Measures
- Pharmacokinetic (PK) Plasma Concentrations of Lanadelumab [Single-dose Cohort: Pre-dose, 1, 24, 72, 144, 216, 336 hours post-dose; Repeat-dose Cohort: Pre-dose, 1, 24, 72, 73, 144, 216, 336 hours post-dose]
Pharmacokinetic plasma concentrations of lanadelumab after a single and repeat intravenous (IV) doses will be assessed.
- Percentage Change from Baseline in Plasma Kallikrein Activity (pKal) [Single-dose Cohort: Pre-dose, 1, 24, 72, 144, 216, 336 hours post-dose; Repeat-dose Cohort: Pre-dose, 72, 144, 216, 336 hours post-dose]
Percentage change from baseline in pKal activity to assess pharmacodynamics (PD) of lanadelumab.
- Percentage Change from Baseline in Cleaved High Molecular Weight Kininogen (cHMWK) [Single-dose Cohort: Pre-dose, 1, 24, 72, 144, 216, 336 hours post-dose; Repeat-dose Cohort: Pre-dose, 72, 144, 216, 336 hours post-dose]
Percentage change from baseline in cHMWK levels to assess PD of lanadelumab.
- Percentage Change from Baseline in Functional C1-Inhibitor (C1-INH) [Single-dose Cohort: Pre-dose, 1, 24, 72, 144, 216, 336 hours post-dose; Repeat-dose Cohort: Pre-dose, 72, 144, 216, 336 hours post-dose]
Percentage change from baseline in functional C1-INH levels to assess PD of lanadelumab.

-
Agree to adhere to the protocol-defined schedule of treatments, assessments, and procedures.
Exclusion Criteria:
-
Invasive mechanical ventilation (IMV) extracorporeal membrane oxygenation (ECMO) or with evidence of severe respiratory distress such that IMV/ECMO is imminent within 12 hours of randomization.
-
Where, in the opinion of the investigator, progression to death is imminent and inevitable within the next 24 hours, irrespective of the provision of treatments.

Any significant condition (any surgical or medical condition) that, in the opinion of the investigator or sponsor, may compromise their safety or compliance, preclude the successful conduct of the study, or interfere with interpretation of the results (e.g. significant pre-existing illness or other major comorbidities that the investigator considers may confound the interpretation of study results).
