New Technologies to Diagnose and Treat a Multidrug-Resistant Candida auris: A Patent Review

Abstract

Candida auris is responsible for hospital outbreaks worldwide. Some C. auris isolates may show concomitant resistance to azoles, echinocandins, and polyenes, thereby possibly leaving clinicians with few therapeutic options. In addition, this multi-drug-resistant yeast is difficult to identify with conventional methods and has the ability to persist on environmental surfaces causing hospital-acquired infections. The development of new treatment options and tools for identification is critical to control, prevent, and establish an early diagnosis of this emerging pathogen. The aim of this study was to perform a critical patent review to explore and identify the latest advances in therapeutic strategies as well as diagnostic methods for C. auris. A total of 19 patents were identified for a preliminary assessment from the Espacenet database. Three patents were excluded as they were out of focus for this review according to their abstract and/or description. The final selection covered 16 patents, which were surveyed by country, year and classified as treatment or diagnostic methods for C. auris. As noted in the patent reading, in recent years, the interest of academic, government and industry sectors have shown an increasing tendency focused on research and development of new therapeutic molecules and diagnostic methods to combat this emerging pathogen.
