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
Larotrectinib is an orally administered inhibitor of tropomyosin receptor kinase (Trk), a receptor tyrosine kinase activated by neurotrophins which is mutated in a variety of cancer cell types and plays an important role in tumor cell growth and survival. Upon administration, larotrectinib binds to Trk, thereby preventing neurotrophin-Trk interaction and Trk activation, which results in both the induction of cellular apoptosis and the inhibition of cell growth in tumors that overexpress Trk. Larotrectinib was granted accelerated approval by the FDA in November 2018 for the treatment of Trk-positive solid tumors. It was notable for being the second tissue-agnostic chemotherapy ever approved by the FDA.
