Brief summary
Study to assess the safety and efficacy of STI-5656 (Abivertinib Maleate) plus SOC versus SOC in subjects hospitalized with COVID-19
Detailed description
This is a Phase 2, open-label, randomized 2-arm multicenter study to assess the safety and efficacy of STI-5656 (Abivertinib Maleate) administered orally plus Standard of Care (SOC) versus SOC in hospitalized subjects with RT-PCR confirmed SARS-CoV-2 infection and COVID-19 pneumonia (documented radiographically). Only hospitalized patients are eligible for this study.
Interventions
Abivertinib maleate is a third-generation EGFR tyrosine kinase inhibitor and BTK Inhibitor. The starting dose is 200 mg p.o. QD for up to 28 days.

Eligibility
Inclusion criteria
* Confirmed infection with SARS-CoV-2 per World Health Organization (WHO) criteria (including positive RT-PCR nucleic acid test of any specimen \[eg, respiratory, blood, urine, stool, or other bodily fluid\]) within 7 days of randomization * Hospitalized with COVID-19 pneumonia (documented radiographically) and oxygen saturation \<94% on room air or subject requires supplemental oxygen * Able to swallow capsules * Willing to follow contraception guidelines * Subject or family member/caregiver must have provided written informed consent which includes signing the institutional review board approved consent form prior to participating in any study related activity. However, if obtaining written informed consent is not possible, other procedures as provided in the March 27th, 2020 FDA Guidance on Conduct of Clinical Trials of Medical Products during COVID-19 Pandemic, Question 10, may be used
Exclusion criteria
* Known cardio-pulmonary resuscitation within 14 days prior to randomization * Pregnant or breast feeding * Suspected uncontrolled active bacterial, fungal, viral, or other infection (besides infection with SARS-CoV-2) * Alanine aminotransferase (ALT) ≥ 3x upper limit of normal (ULN) and total bilirubin \> 2x ULN * QTcF prolongation \>480 milliseconds * Uncontrolled or untreated symptomatic arrhythmias, myocardial infarction within the last 6 weeks, or congestive heart failure (NYHA Grade 3 or 4).

Percentage of Subjects Alive and Free of Respiratory Failure at Day 28
Percentage of subjects alive and free of respiratory failure at Day 28, where respiratory failure, is defined based on resource utilization of any of the following modalities: * Noninvasive positive pressure ventilation or continuous positive airway pressure * Endotracheal intubation and mechanical ventilation * Oxygen delivered by high-flow nasal cannula (heated, humidified, oxygen delivered via reinforced nasal cannula at flow rates \>20L/min with fraction of delivered oxygen ≥ 0.5) * Extracorporeal membrane oxygenation
Time frame: Randomization to Day 28
Population: A total of 48 subjects in the STI-5656 group and 48 subjects in the placebo group were included in the analysis of the primary endpoint in the FAS. For a number of the excluded subjects, the reason for exclusion from the primary endpoint analysis was that they had no baseline value available.
