MBP 88.0 Halaven (eribulin mesylate)
Halaven (eribulin) is a nontaxane microtubule dynamics inhibitor that inhibits the growth phase of microtubules without affecting the shortening phase, and sequesters tubulin into nonproductive aggregates. Eribulin exerts its effects via a tubulin-based antimitotic mechanism leading to G2/M cell-cycle block, disruption of mitotic spindles, and, ultimately, apoptotic cell death after prolonged mitotic blockage
MBP 179.0 Hemlibra (emicizumab-kxwh)
Hemlibra (emicizumab-kxwh) is a humanized monoclonal modified immunoglobulin G4 (IgG4) antibody with a bispecific factor IXa- and factor X-directed antibody, bridges activated factor IX and factor X to restore the function of missing activated factor VIII that is needed for effective hemostasis. Emicizumab-kxwh has no structural relationship or sequence homology to FVIII and, therefore, does not induce or enhance the development of direct inhibitors to FVIII.
