PERTH, Australia – In the second multi-billion-dollar pharma merger this week, CSL Ltd. has announced plans to buy Vifor Pharma Ltd. for an equity value of $11.7 billion. It’s also the second largest biopharma merger of 2021, a whisker above Merck & Co Inc.’s $11.5 billion acquisition of Acceleron Pharma Inc. in November, although way off Astrazeneca plc’s $39 billion buy of Alexion Pharmaceuticals Inc. in July.
Clonal hematopoiesis of indeterminate potential (CHIP) was associated with a 35% reduced risk of Alzheimer's disease (AD) in studies presented at the plenary session of the American Society of Hematology (ASH) annual meeting on Sunday.
NHS England has struck new pricing agreements that expands access in the U.K. to blood thinning direct oral anticoagulants (DOACs) to tackle strokes in patients with atrial fibrillation. Though still available to NHS clinicians, Boehringer Ingelheim GmbH’s blockbuster DOAC Pradaxa (dabigatran) is notably not involved.
Catalyst Biosciences Inc. decided to stop developing marzeptacog alfa (MarzAA), a recombinant human coagulation factor VIIa variant for treating factor VII deficiency, and sell its hemophilia assets to focus on its complement therapeutics and protease medicines platform.
Results from two pivotal phase III trials testing Glaxosmithkline plc's daprodustat against anemia due to chronic kidney disease (CKD) found the oral hypoxia-inducible factor prolyl hydroxylase inhibitor helped both non-dialysis and dialysis patients improve or maintain hemoglobin levels without increased cardiovascular risk vs. standard-of-care erythropoietin stimulating agents. Though already approved in Japan as Duvroq, what future the drug might face in the U.S., where the same-class drug roxadustat garnered an FDA complete response letter, remained an open question.
LONDON – The EMA recommended approval of Apellis Pharmaceuticals Inc.’s C3 complement inhibitor, Aspaveli (pegcetacoplan), to treat paroxysmal nocturnal hemoglobinuria, but has diverged from the FDA, excluding treatment-naïve patients adding its use should be restricted to those who have failed to respond to C5 inhibitor drugs.
In the year’s second biggest M&A deal, Merck & Co. Inc. will take over pulmonary and hematologic specialist Acceleron Pharma Inc. for $11.5 billion. The acquisition brings Merck a pair of potential blockbuster drugs, one of them already marketed. There is sotatercept, in development for treating pulmonary hypertension (PH), and also Reblozyl (luspatercept-aamt), the first and only erythroid maturation agent approved in the U.S., Europe and Canada for treating anemia in certain blood disorders.
Shares of Protagonist Therapeutics Inc. (NASDAQ:PTGX) fell 62% to $17.53 on Sept. 17 after it reported finding malignant skin tumors in a mouse model test of its most advanced candidate, rusfertide for blood disorders. After the company notified the FDA, the regulator put the program on a clinical hold, leading dosing of patients in all ongoing trials of rusfertide to be halted for now. The development could impact Protagonist's ability to start phase III testing of the candidate in polycythemia vera (PV) early in 2022, as well as efforts to expand its development to a third indication beyond PV and hereditary hemochromatosis (HH) by the end of this year, as it has planned.
