Who could benefit from this research

Could help

Ideal candidates would have or be at high risk for MDR Gram-negative infections, such as CRE, particularly in healthcare settings.

Less likely to help

Patients without MDR Gram-negative infections may not benefit from this research.

What this research studies

This grant supports preclinical development of a novel macrocyclic peptide, Orynotide MTD12813, aimed at tackling MDR Gram-negative infections such as CRE. The work builds on theta-defensin biology to create host-directed antimicrobials with potential to work where traditional antibiotics fail. Researchers will use preclinical models to show how Orynotide acts in the body and to optimize its safety and effectiveness before human testing. The project is led by Justin Blaine Schaal at the University of Southern California and plans a path toward eventual clinical evaluation for patients in need of new treatments.

Why it matters

Potential benefit: If successful, this work could lead to a new therapeutic option for patients with MDR Gram-negative infections.

How similar studies have gone: Prior studies with host-directed antimicrobials have shown promise in preclinical models, supporting potential progress with Orynotides.
