Details and patient eligibility

About

The purpose of this study is to determine the safe use and evaluate the efficacy/performance of DAV132 in hospitalized patients at high risk for Clostridium difficile infection (CDI) and who receive fluoroquinolones (FQs) for the treatment of acute infections or for prophylaxis of febrile neutropenia.

Full description

Da Volterra develops DAV132, a novel therapeutic option preserving the intestinal microbiota, to prevent potentially life-threatening conditions such as CDI or emergence of antibiotic-resistant bacteria. Prevention of CDI remains critical unmet need, especially for patients at high risk of developing such infection.
