Four new U.S. drug approvals, one accelerated for need, have handed a string of year-end victories to five drugmakers, marking an unusually active start to a week full of global holiday celebrations. Daiichi Sankyo Co. Ltd., Astrazeneca plc, Eisai Inc., Intra-Cellular Therapies Inc. and Allergan plc all secured new approvals from the agency. Daiichi's Enhertu (trastuzumab deruxtecan), the subject of a $6.9 billion deal with Astrazeneca, won accelerated approval for the third-line treatment of adults with unresectable or metastatic HER2-positive breast cancer. Eisai's Dayvigo (lemborexant) was approved to treat insomnia. Intra-Cellular's Caplyta (lumateperone) was approved to treat schizophrenia. Allergan’s Ubrelvy (ubrogepant) became the first of a relatively new class of drugs to be approved for the acute treatment of migraine.

While Ebola virus disease in the U.S. is a rare occurrence, the FDA approval of Merck & Co. Inc.’s Ervebo, the agency’s first for preventing Ebola Zaire virus in people age 18 and older, will have a ripple effect across the world, especially Africa where its effects have been devastating for decades. Stockpiling such a vaccine is crucial to world safety as Ebola has long been a potential bioterrorism threat, especially after 9/11. In the world of theoretical biological warfare, where the virus could be weaponized and disseminated by aerosol, Ebola virus is considered the most dangerous, with fatality rates estimated between 25% to 90%.
