Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Lung failure is the main cause of death related to COVID-19 infection. The main objective of this study was to evaluate if ibrutinib is safe and can reduce respiratory failure in participants with COVID-19 infection.
This was a Phase 2, multicenter, randomized, placebo-controlled, double-blind study to
evaluate the addition of ibrutinib to supportive care in hospitalized participants who
presented with COVID-19- related pulmonary distress requiring supplemental oxygen.
Participants were randomized in a 1:1 ratio to receive placebo + supportive care, denoted as
SOC or standard-of-care, or ibrutinib 420 mg + SOC, with randomization stratified by
prescription for remdesivir.
Participants were to be treated with either placebo or ibrutinib in addition to supportive
care for up to 28 days unless they met treatment discontinuation criteria and were to be
followed for 58 days following start of therapy or until death, whichever occurred first.
Treatment could have been stopped at the discretion of the treating physician after 14 days
if the participant was clinically stable and had been off supplemental oxygen for > 48 hours.
Drug: Ibrutinib
Capsules were to be administered orally with water once daily. For participants who required nasogastric tube (NGT) placement while on study, capsules may have been administered by opening the capsules, mixing with water, and flushing down the NGT.
Other Name: Imbruvica
Drug: Placebo
Capsules were to be administered orally with water once daily. For participants who required nasogastric tube (NGT) placement while on study, capsules may have been administered by opening the capsules, mixing with water, and flushing down the NGT.
