Batimastat (INN/USAN, codenamed BB-94) is an anticancer drug that belongs to the family of drugs called angiogenesis inhibitors. It acts as a matrix metalloproteinase inhibitor (MMPI) by mimicking natural MMPI peptides.

Batimastat was the first MMPI that went into clinical trials. First results of a Phase I trial appeared in 1994. The drug reached Phase III but was never marketed; mainly because it couldn't be administered orally (as opposed to the newer and chemically similar MMPI marimastat), and injection into the peritoneum caused peritonitis.[1]
