Fidaxomicin is a novel macrolide antibiotic used in the treatment of diarrhea caused by _Clostridioides_ (formerly _Clostridium_) _difficile_ in adult and pediatric patients over the age of 6 months. Fidaxomicin is a naturally-occurring 18-member macrocycle derived from fermentation. Because fidaxomicin contains an 18-membered lactone ring in its structure, it is referred to as a macrocyclic lactone antibiotic drug. The antibacterial activity of fidaxomicin is distinct from macrolides and rifamycins, as the bactericidal activity is time-dependent, and not concentration-dependent. Fidaxomicin was the first macrocyclic lactone antibiotic with activity against _C. difficile_, and it displays a narrow spectrum of activity against gram-positive anaerobes. It mediates its potent bactericidal action on the bacteria by inhibiting the bacterial RNA synthase
Neratinib was approved in July 2017 for use as an extended adjuvant therapy in Human Epidermal Growth Factor Receptor 2 (HER2) positive breast cancer. Approval was granted to Puma Biotechnology Inc. for the tradename Nerlynx. Neratinib is currently under investigation for use in many other forms of cancer.
