Working with US FDA was key to developing clinical trials in the absence of regulatory precedents in recurrent vulvovaginal candidiasis, Scynexis VP tells the Pink Sheet; exposure profiles drove different trial designs for Scynexis’ Brexafemme and Mycovia’s just-launched Vivjoa.

The Swiss biotech says the ERADICATE trial shows areas of differentiation for the antibiotic, like utility in pneumonia and across gram-negative and gram-positive bacteria.

Entasis is seeking a pathogen-specific approval for its antibiotic/beta lactamase inhibitor candidate rather than an indication specific the site of an infection. Achaogen’s earlier failure to do the same may have helped set a path.

With Phase III data showing non-inferiority to colistin, as well as nephrotoxicity superiority, Entasis thinks sulbactam/durlobactam will provide a new standard of care and succeed where Achaogen’s Zemdri failed.
