SAD/MAD Safety and PK Study of QPX9003 (Novel Polymyxin) in Normal Healthy Volunteers

Completed · Phase 1 · Has a placebo group

Conditions studied: Bacterial Infections

In brief

The worldwide spread of resistance to antibiotics among gram-negative bacteria, particularly members of the ESKAPE group of pathogens, has resulted in a crisis in the treatment of hospital acquired infections. In particular, the presence of multi-drug resistant Acinetobacter baumannii and Pseudomonas aeruginosa in hospitals around the world poses a considerable threat. .
