Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
434 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How participants are assigned to different groups/arms
In this clinical study, participants are placed into groups randomly, like flipping a coin. This ensures that the study is fair and unbiased, making the results more reliable. By assigning participants by chance, researchers can better compare treatments without external influences.

Other Ways to Assign Participants
Non-randomized allocation: Participants are assigned based on specific factors, such as their medical condition or a doctor's decision.
None (Single-arm trial): If the study has only one group, all participants receive the same treatment, and no allocation is needed.

How the interventions assigned to participants is kept confidential
Neither participants nor researchers know who is receiving which treatment. This is the most rigorous way to reduce bias, ensuring that expectations do not influence the results.

Other Ways to Mask Information
Open-label: Everyone knows which treatment is being given.
Single-blind: Participants do not know which treatment they are receiving, but researchers do.
Triple-blind: Participants, researchers, and outcome assessors do not know which treatment is given.
Quadruple-blind: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.

Criteria

Inclusion Criteria: * Male and female subjects ≥ 18 years of age and in Bulgaria only ≤ 70 years of age * Subjects hospitalized with CAP with a severity that requires IV antibiotic treatment for at least 7 days * The presence of fever (within 24 hours before randomization) Exclusion Criteria: * Any concomitant condition that, in the opinion of the investigator, would preclude an evaluation of a response or make it unlikely that the contemplated course of therapy could be completed (eg, life expectancy \<30 days). * Hospitalization within 14 days before the onset of symptoms. * Residence in a long-term care facility or nursing home ≥14 days before the onset of symptoms.
