Overview

An Open-Label, Multiple-Ascending Dose, Multicenter Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of LSVT-1701 as an Add-on to Standard of Care Antibiotics for the Treatment of Complicated Methicillin-Sensitive and -Resistant Staphylococcus Aureus Bacteremia Including Left- and Right-sided Infective Endocarditis

This study evaluates safety and tolerability of endolysin-derived LSVT-1701 (tonabacase) as an add-on to standard of care (SOC) antibiotic therapy for the treatment of patients with complicated Staphylococcus aureus bacteremia (SAB), including left- and right-sided infective endocarditis (IE).

Thirty-two healthy male subjects (8 per cohort) were randomized 6:2 to active:placebo. LSVT-1701, an antistaphylococcal lysin, was administered intravenously as a 6-mg/kg single dose and as 1.5, 3, and 4.5 mg/kg twice daily for 4 days.

Anti-staphylococcal lysin, LSVT-1701, activity: In vitro susceptibility of Staphylococcus aureus and coagulase-negative staphylococci (CoNS) clinical isolates from around the world collected from 2002 to 2019

LSVT-1701 (previously known as SAL200), is a novel, recombinantly-produced, bacteriophage-encoded lysin that specifically targets staphylococci via cell wall enzymatic hydrolysis. In vitro activities of LSVT-1701 and comparators were tested against 415 Staphylococcus aureus and coagulase-negative staphylococci (CoNS) clinical isolates expressing various resistance phenotypes. The isolates were collected worldwide from 2002 to 2019 and tested for in vitro susceptibility using broth microdilution methodology performed according to the Clinical and Laboratory Standards Institute (CLSI) guidelines. Minimum inhibitory concentration (MIC) interpretations were based on CLSI and EUCAST criteria. MIC₉₀ for all S. aureus, methicillin-susceptible S. aureus, methicillin-resistant S. aureus, and CoNS, were 2, 2, 2 and 2 µg/ml, respectively. LSVT-1701's activity was not adversely affected by resistance to antimicrobial comparators against this worldwide collection of S. aureus and CoNS clinical isolates. The results of this study support further clinical development of LSVT-1701 to treat staphylococcal infections, including those caused by multidrug resistance isolates.

Efficacy of Antistaphylococcal Lysin LSVT-1701 in Combination with Daptomycin in Experimental Left-Sided Infective Endocarditis Due to Methicillin-Resistant Staphylococcus aureus

Q2 · MEDICINE

We utilized the rabbit model of aortic valve infective endocarditis to examine the combined efficacy of the lysin LSVT-1701 plus daptomycin. The combination of LSVT-1701 plus daptomycin was highly effective at reducing methicillin-resistant Staphylococcus aureus (MRSA) counts in target tissue.
