Exebacase in Addition to Standard-of-Care Antibiotics for Staphylococcus aureus Bloodstream Infections and Right-Sided Infective Endocarditis: A Phase 3, Superiority-Design, Placebo-Controlled, Randomized Clinical Trial (DISRUPT).

Background: Novel treatments are needed for Staphylococcus aureus bacteremia, particularly for methicillin-resistant S. aureus (MRSA). Exebacase is a first-in-class antistaphylococcal lysin that is rapidly bactericidal and synergizes with antibiotics.

Rapid bacteriolysis of by lysin exebacase.

Lysins (peptidoglycan hydrolases) are promising new protein-based antimicrobial candidates under development to address rising antibiotic resistance encountered among pathogenic bacteria. Exebacase is an antistaphylococcal lysin and the first member of the lysin class to have entered clinical trials in the United States. In this study, the bacteriolytic activity of exebacase was characterized with time-kill assays, turbidity reduction assays, and microscopy.

Paediatric palliative care for the generalist.

Palliative care has been defined as 'the active holistic care of individuals across all ages with serious health-related suffering due to severe illness, and especially of those near the end of life'. Unfortunately, palliative care and especially paediatric palliative care remain a neglected area of medicine and are widely misunderstood, with few healthcare providers having any formal training in South Africa. To relieve health-related suffering, healthcare providers must understand that the field is not limited to end-of-life care for the terminally ill, and holistic care (physical, emotional, social and spiritual) should commence at the time of diagnosis of a serious illness.

The Lysin Exebacase Has a Low Propensity for Resistance Development in Staphylococcus aureus and Suppresses the Emergence of Resistance to Antistaphylococcal Antibiotics.

Exebacase (CF-301) belongs to a novel class of protein-based antibacterial agents, called lysins (peptidoglycan hydrolases). Exebacase exhibits potent antistaphylococcal activity and is the first lysin to initiate clinical trials in the United States. To support clinical development, the potential for resistance development to exebacase was assessed over 28 days of serial daily subculture in the presence of increasing concentrations of the lysin performed in its reference broth medium.
