Shanghai MicuRx Pharmaceutical Co., Ltd. („MicuRx“?688373.SH) announced that MRX-5, its self-developed anti-infection drug, has been granted Orphan Drug Designation (ODD) by the U.S. Food and Drug Administration (FDA) for the treatment of non-tuberculous mycobacteria (NTM) infections. This designation marks a significant milestone for MicuRx in the field of NTM infection treatment.
MRX-5 is a novel benzoxazole antibiotic developed for the treatment of mycobacteria infections, particularly infections caused by non-tuberculous Mycobacteria (NTM). In recent years, NTM diseases have been increasing rapidly and have become one of the major public health threats worldwide[1]. However, current treatment options for NTM infections are limited, and traditional drugs face common challenges such as drug resistance, poor efficacy, and numerous adverse effects[1,2].
MRX-5 is a new drug specifically aimed at treating drug-resistant NTM infections, demonstrating good antibacterial activity against common NTM strains. It has also shown potent antibacterial activity against NTM pathogens in both animal studies and human trial, along with favorable safety and pharmacokinetic profiles. Additionally, MRX -5 features minimal interactions, low potential for resistance, and high oral bioavailability, making it suitable for long-term use in treating chronic infections.
