Our pipeline.

A deep bench against drug-resistant infection — one Phase 3-ready asset, one first-in-class lead in development, and earlier-stage candidates behind them.

Programs

Anti-infective programs in development.

Fedora is advancing a portfolio designed to address serious infections caused by drug-resistant bacteria, including a novel antibiotic and a β-lactamase inhibitor program.

Nacubactamβ-lactamase inhibitor + meropenem
Phase 3-ready · Available for partnership

A β-lactamase inhibitor with a unique dual mechanism — combining enzyme inhibition with direct antibacterial activity — for serious drug-resistant bacterial infections, including complicated urinary tract infections and carbapenem-resistant Enterobacterales.

Current lead · Available for partnership

A first-in-class, non-β-lactam penicillin-binding protein inhibitor derived from the lactivicin family of natural products — the first from this class to advance toward the clinic — with potent activity against multidrug-resistant Gram-negative pathogens.

The science

We disarm the enzymes that make antibiotics fail.

Bacteria produce β-lactamase enzymes that destroy β-lactam antibiotics — penicillins, cephalosporins, and carbapenems. Those three classes account for over 60% of every antibiotic prescribed. Fedora's inhibitors shut the enzymes down and put the drugs back to work.

1
The threat.
Resistant bacteria produce β-lactamases that neutralize front-line antibiotics.
2
Our inhibitor.
Nacubactam blocks those enzymes through several mechanisms at once.
3
The result.
Paired with meropenem, it works even against carbapenem-resistant strains.
