简要总结
Multicenter double-blind placebo-controlled randomized in parallel groups clinical trial.
详细描述
Design: a multicenter, double-blind, placebo-controlled, randomized in parallel-group trial.
The study enrolls male and female outpatients aged 18 to 65 years with typical symptoms of community-acquired pneumonia (CAP): axillary body temperature ≥38.00C, acute cough, shortness of breath (dyspnea), chest pain when breathing, fatigue, night sweats. Symptoms are associated with previous upper respiratory tract infection or acute bronchitis. The investigator assesses a prognosis and determines where the patient will receive treatment using the CRB-65 score which includes estimation of Confusion, Respiratory rate, Blood pressure, and Age (≥ 65 years) (min "0", max "4" points; only estimation "0" points is indication for outpatient treatment).
At the first visit (day 1), after signing the patient information sheet and informed consent form for participation in a clinical trial, the investigator collects complaints and medical history, conducts a physical examination and assessment of vital signs, and measures capillary blood oxygen saturation (SpO2), records comorbidities and concomitant therapies, collects blood samples for laboratory tests, and orders a dual-view chest X-ray or chest CT scan. If X-ray/CT shows no changes in the lungs or changes that are not typical for pneumonia, the patient is not included in the clinical trial. The investigator determines a therapeutic approach in compliance with the current standards.
At the first visit (day 1), patients are randomized to one of two treatment groups: patients in Group 1 receive Amoxicillin + Clavulanic acid (Amoxiclav) and Rafamine for 7 days; patients in Group 2 take Amoxiclav and Placebo for 7 days. All patients are provided with the drug Amoxiclav. In addition, all patients are provided with the antipyretic drug Paracetamol and a classic mercury-free thermometer to measure axillary temperature.
A second visit (3/4 days) is carried out 48-72 hours after the start of treatment to assess the effectiveness and safety of the initial course of antibiotic therapy. The investigator collects complaints, performs physical examination, and evaluates the vital signs and SpO2 level. If there is no response to initial antibiotic therapy, the decision about the therapeutic approach is made by the investigator. If hospitalization occurs, the patient ends participation in the study because he or she has reached the study endpoint.
