Our lead product APC301 (meropenem + APC148 + avibactam) was tested in vitro in 176 MBL- and SBL-producing bacteria (Enterobacterales) against competitor products. APC301 was the most potent product in these highly resistant pathogens. Our follow-up product APC302 (cefepime+APC148+avibactam) showed similar good effects and gives great promise in targeting a broad patient population. To address other serious bacterial infections, we are testing new drug combinations based on our APC148 technology.
