Clinical Trial Summary

This clinical study was designed to assess the efficacy and safety of DFV890 for the treatment of severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) infected patients with coronavirus disease 2019 (COVID-19) pneumonia and impaired respiratory function.

Description:

This was a Phase II, randomized, controlled, open label multi-center study to assess the efficacy and safety of DFV890 for the treatment of SARS-CoV-2 infected patients with COVID-19 pneumonia and impaired respiratory function. The study consisted of four distinct study periods: Screening / Baseline visit (Day -1 to 1): lasted up to a maximum of 24 hours and comprised a screening / baseline assessment. This visit was used to confirm that the study inclusion and exclusion criteria were met and served as baseline assessment prior to randomization. Treatment period (Day 1-15): Participants were randomized as soon as possible, but within a maximum of 24 hours after screening in a 1:1 ratio receiving either DFV890 in addition to standard of care (SoC) or SoC alone. Participants in the investigational treatment arm received DFV890 administered for a total of 14 days in addition to SoC. Participants in the control arm received SoC alone. Study assessments were conducted every 2 days for hospitalized participants. The End of Treatment (EOT) visit took place on Day 15. If participants were discharged from the hospital prior to Day 15, assessments on the day of discharge were performed according to the schedule listed under Day 15; participants continued to take the investigational treatment at home to complete the 14-day treatment period and the participants returned to the site for the Day 15/EOT assessment. If a hospital visit was not possible at Day 15, then home nursing services were used to support the last visit. Follow-up (Day 16-29): After completion of the treatment period, participants were observed until Day 29 or discharged from hospital, whichever was sooner. Study assessments were conducted every 2 days for hospitalized participants. If participants were discharged from hospital prior to Day 29, a study visit conducted by telephone was performed on Day 29. 30-day safety follow-up assessment (Day 45): A follow-up visit for safety was conducted by telephone.

• Absolute peripheral blood neutrophil count of =1000/mm3.
• Estimated GFR (eGFR) =30 mL/min/1.73m2 (based on CKD-EPI formula).
• Patients currently being treated with drugs known to be strong or moderate inducers of isoenzyme CYP2C9 and/or strong inhibitors of CYP2C9 and/or strong inducers of cytochrome P450, family 3, subfamily A (CYP3A) and the treatment cannot be discontinued or switched to a different medication prior to starting study treatment.
• Patients with innate or acquired immunodeficiencies.
• Patients who have undergone solid organ or stem cell transplantation.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	APACHE II Severity of Disease Score on Day 15 or on the Day of Discharge (Whichever is Earlier)	The APACHE II ("Acute Physiology And Chronic Health Evaluation II") is a severity-of-disease classification system. An integer score from 0 to 71 is computed based on several measurements; higher scores correspond to more severe disease and a higher risk of death. In practice, it is rare for any participant to accumulate more than 55 points.; APACHE II score was measured on Day 15 or on the day of discharge (whichever was earlier). Participants who died on Day 15 or earlier were assigned the highest observed APACHE II score of any of the participants at any time during the trial (worst case imputation for deaths). Missing data values of the parameters required for the derivation of the APACHE II score were replaced by the last available assessment.	up to Day 15
Secondary	Serum C-reactive Protein (CRP) Levels	C-reactive protein (CRP) is a blood test marker for inflammation in the body. It was analyzed on a log-scale fitting a repeated measures mixed model including treatment group, study day, the three stratification factors and log transformed baseline CRP as a covariate. Values reported were back-transformed to original scale.	Days 2, 4, 6, 8, 10, 12, 14 and 15
Secondary	Clinical Status Over Time	Clinical status was measured with World Health Organization (WHO) 9-point ordinal scale.; The scoring is - Uninfected patients have a score 0. - Ambulatory patients can have a score 1 (no limitation of activities) or 2 (limitation of activities). - Hospitalized patients with mild disease can have score 3 (no oxygen therapy) or 4 (oxygen by mask or nasal prongs). - Hospitalized patients with severe disease can have score 5 (non-invasive ventilation or high-flow oxygen), 6 (intubation and mechanical ventilation) or 7 (ventilation + additional organ support - pressors, renal replacement therapy, extracorporeal membrane oxygenation). - Patients who die have a score 8.; Missing data values were handled as follows: For participants who died prior to Day 29, the score for death was imputed for all following visits up to and including day 29. For all the other participants, last observation carried forward was applied up to and including Day 29.	Baseline, days 2, 4, 6, 8, 10, 12, 14, 15, 17, 19, 21, 23, 25, 27 and 29
Secondary	Number of Participants Not Requiring Mechanical Ventilation for Survival	Number of participants not requiring mechanical ventilation for survival until Day 15 and Day 29: defined by WHO 9-point ordinal scale score of < 6 points at all time points assessments.; The scoring is - Uninfected patients have a score 0. - Ambulatory patients can have a score 1 (no limitation of activities) or 2 (limitation of activities). - Hospitalized patients with mild disease can have score 3 (no oxygen therapy) or 4 (oxygen by mask or nasal prongs). - Hospitalized patients with severe disease can have score 5 (non-invasive ventilation or high-flow oxygen), 6 (intubation and mechanical ventilation) or 7 (ventilation + additional organ support). - Patients who die have a score 8.; Missing data values were handled as follows: For participants who died prior to Day 29, the score for death was imputed for all following visits up to and including day 29. For all the other participants, last observation carried forward was applied up to and including Day 29.	Until Day 15 (Assessments on Days 2, 4, 6, 8, 10, 12, 14 and 15) and until Day 29 (Assessments on Days 17, 19, 21, 23, 25, 27 and 29)
Secondary	Number of Participants With at Least One-point Improvement From Baseline in Clinical Status	Number of participants with at least one-point improvement from baseline in clinical status, which was measured with WHO 9-point ordinal scale.; The scoring is - Uninfected patients have a score 0. - Ambulatory patients can have a score 1 (no limitation of activities) or 2 (limitation of activities). - Hospitalized patients with mild disease can have score 3 (no oxygen therapy) or 4 (oxygen by mask or nasal prongs). - Hospitalized patients with severe disease can have score 5 (non-invasive ventilation or high-flow oxygen), 6 (intubation and mechanical ventilation) or 7 (ventilation + additional organ support). - Patients who die have a score 8.; Missing data values were handled as follows: For participants who died prior to Day 29, the score for death was imputed for all following visits up to and including day 29. For all the other participants, last observation carried forward was applied up to and including Day 29.	Baseline, Day 15 and Day 29
