Baricitinib (LY3009104) 在 COVID-19 (COV-BARRIER-PEDS) 患儿中的研究 (COV-BARRIER)

• Participants received baricitinib as an oral suspension (2 milligrams per milliliter [mg/mL]) administered once daily (QD), with age group-based dosing: 4 milligrams (mg) for participants aged 10 to <18 years and up to 2 mg for those aged 1 to <10 years.
• Treatment was administered for up to 14 days or until hospital discharge, whichever occurred first, with follow-up assessments through approximately Day 60.

NIAID-OS is an assessment of clinical status. The scale is as follows: 1)Not hospitalized, no limitations on activities; 2)Not hospitalized, limitation on activities and/or requiring home oxygen; 3)Hospitalized, not requiring supplemental oxygen - no longer requires ongoing medical care; 4)Hospitalized, not requiring supplemental oxygen - requiring ongoing medical care (COVID-19 related or otherwise); 5)Hospitalized, requiring supplemental oxygen; 6)Hospitalized, on non-invasive ventilation or high-flow oxygen devices; 7)Hospitalized, on invasive mechanical ventilation or ECMO; 8)Death. NIAID-OS (range: 1-8); minimum value: 1 (not hospitalized, no limitations on activities); maximum value: 8 (death); higher scores indicate worse clinical status.

Progression to ventilation (only progressed excluding death) by Day 28 was defined as reaching NIAID-OS ≥6; for participants with baseline NIAID-OS 6, progression required NIAID-OS ≥7, and those with a baseline score of 7 were excluded.

Time to recovery was time from Day 1 to the first day the participant's maximum daily NIAID-OS was 1, 2, or 3. Participants who died before recovery were censored at Day 28 (not considered recovered).

Improvement was defined as the reduction from baseline in the NIAID-OS score, calculated as baseline score minus Day 4 score. A higher positive value indicates greater improvement.

Duration of hospitalization through Day 28 was defined as the total number of days with NIAID-OS scores of 4, 5, 6, or 7. Participants who died on or before Day 28 were assigned 28 days. For Day 1, hospitalization status was determined using worst NIAID-OS value recorded between baseline and the remainder of Day 1.
