Efficacy and Safety of Trimodulin (BT588) in Subjects With CAP Including COVID-19 Pneumonia

This is a randomized, placebo-controlled, double-blind, multi-center, phase III trial to assess the efficacy and safety of trimodulin compared to placebo treatment, adjunctive to SoC in adult hospitalized subjects with non-severe community-acquired pneumonia (CAP) or moderate / severe Coronavirus Disease 2019 (COVID-19) pneumonia. Patients requiring low-flow oxygen, non-invasive ventilation or high-flow oxygen and with signs of early systemic inflammation (defined by C reactive protein (CRP), D-dimer and platelet levels) will be enrolled.

Subjects will be randomized to receive either trimodulin or placebo on a 1:1 basis, stratified by type of oxygen supply before randomization and by region. Investigational Medicinal Product (IMP) treatments will be blinded. Subjects will be administered IMP once daily on five consecutive days (day 1 through day 5) adjunctive to SoC. The subsequent follow-up phase comprises maximally 23 days (day 6 through day 28) followed by an end-of-follow-up visit/telephone call on day 29 \[+3\]. For all subjects still in the hospital after day 29, an extended follow-up visit is conducted until day 90 or until discharge. For all subjects a closing visit/telephone call on day 91 \[+10\] will be done.

For the evaluation of the primary and several secondary endpoints of the trial, a 9-category ordinal scale will be used. The primary objective is to assess efficacy of trimodulin based on clinical deterioration and mortality to demonstrate superiority to treatment with placebo. Secondary objectives are to assess efficacy and safety and to determine PK and PD properties of trimodulin compared to placebo.
