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
Venetoclax is a BCL-2 inhibitor that was initially approved by the FDA in April 2016 [FDA label]. Proteins in the B cell CLL/lymphoma 2 (BCL-2) family are important regulators of the apoptotic (programmed cell death) process , . Venetoclax is used to treat chronic lymphocytic leukemia (CLL) and certain types of small lymphocytic lymphoma [FDA label]. CLL is the most prevalent leukemia diagnosed in Western countries . Venetoclax was developed through reverse engineering of the BCL-2 protein family inhibitor, navitoclax . Venetoclax is approximately 10 times more potent than navitoclax with regard to induction of apoptosis in CLL cells . A new indication was approved in 2018 for the treatment patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL), with or without 17p deletion, who have received at least one prior therapy [FDA label]. Previously, this drug was indicated only for patients with 17p gene deletion .
