Brief Summary
The primary objective of the REACT randomized clinical trial (RCT) is to optimize the clinical benefit from adjunctive clarithromycin treatment shown in the ACCESS trial and to provide evidence for the clinical benefit of early start of adjunctive oral clarithromycin guided by suPAR to prevent the progression into sepsis in patients with community-acquired pneumonia (CAP) at risk. This can be achieved by endpoints incorporating clinical benefit with the effect of treatment on the improvement of the immune dysregulation of CAP. The secondary objectives of REACT are to investigate the impact of early adjunctive treatment with clarithromycin on the resolution of CAP at the test-of-cure (TOC) visit.

Outcome Measures
Primary Outcomes (3)
Change of baseline respiratory symptoms score
At least 50 percent (%) decrease of the sum of scoring (0-12) for the symptoms of cough (0-3), dyspnea (0-3), purulent sputum expectoration (0-3) and pleuritic chest pain (0-3) between baseline and Study Day 4
4 Days
Change of baseline total sequential organ failure assessment (SOFA) score
At least 30 percent (%) decrease between baseline sequential organ failure assessment (SOFA) score and measured sequential organ failure assessment (SOFA) score at Study Day 4.
4 Days
Change of baseline on both plasma PCT and plasma IL-10 or IL-8 to IL-10 ratio
Plasma PCT on visit 4 has decreased by at least 80% from baseline PCT on screening or it is below 0.25 ng/ml AND (\[plasma IL-10 on visit 4 has decreased by at least 25% from IL-10 of visit 1 or it is below the lower limit of detection\] OR \[the IL-8 to IL-10 ratio of day 4 has decreased less than 15% from the IL-8 to IL-10 ratio of visit 1\]).
4 Days
Secondary Outcomes (9)

Study Arms (2)
Placebo
PLACEBO COMPARATORThese patients will be treated with 1 placebo tablet every 12 hours and it is suggested that all patients receive at least one of antibiotics based on the current ESCMID guidelines for severe CAP13 (Ampicillin/sulbactam, Amoxicillin/clavulanate, Piperacillin/tazobactam, Ceftriaxone, Cefotaxime, Ceftaroline, Moxifloxacin). The total duration of treatment will be seven days.Τhe dosage, the dosage regime, the route and mode of administration, and the treatment period for the aforementioned antibiotics can be found in the relevant SmPCs (available in References). However, the attending physician may modify the antimicrobial treatment based on risk factors for multidrug-resistance pathogens, microbiology results and local epidemiology. All SoC treatment products and clarithromycin are authorised for use in Greece, where the trial will be conducted.
Clarithromycin
ACTIVE COMPARATORThese patients will be treated with oral clarithromycin 500 mg twice daily for seven days and it is suggested that all patients receive at least one of antibiotics based on the current ESCMID guidelines for severe CAP13 (Ampicillin/sulbactam, Amoxicillin/clavulanate, Piperacillin/tazobactam, Ceftriaxone, Cefotaxime, Ceftaroline, Moxifloxacin). The total duration of treatment will be seven days.Τhe dosage, the dosage regime, the route and mode of administration, and the treatment period for the aforementioned antibiotics can be found in the relevant SmPCs (available in References). However, the attending physician may modify the antimicrobial treatment based on risk factors for multidrug-resistance pathogens, microbiology results and local epidemiology. All SoC treatment products and clarithromycin are authorised for use in Greece, where the trial will be conducted.
