The release of the FDA’s briefing document for a Dec. 8 meeting of its Cardiovascular and Renal Drugs Advisory Committee triggered heavy trading and a 38% drop in value in Reata Pharmaceuticals Inc., of Plano, Texas.
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.
Fibrogen Inc. was braced for receiving a complete response letter (CRL) and it got one. The FDA suggested it would not approve roxadustat’s NDA for treating anemia of chronic kidney disease until more clinical work is conducted. In July, the FDA’s Cardiovascular and Renal Drugs Advisory Committee said basically the same thing as it voted 13-1 against approval for the nondialysis population and 12-2 against approval for patients on dialysis unless more trial data are submitted.
Shares in Ardelyx Inc. have crashed after its tenapanor, under FDA review for managing phosphate levels in chronic kidney disease (CKD), ran into trouble with the regulator. The company said that the FDA has identified “deficiencies” in the data package, which prevent discussions about labeling and postmarketing commitments.
Despite assembling the largest body of data the FDA said it may ever see for a drug intended to treat anemia due to chronic kidney disease, Fibrogen Inc. will have to get even more trial data to push roxadustat over the finish line in the U.S. – if the FDA follows the advice of its Cardiovascular and Renal Drugs Advisory Committee.
Safety will be the focus July 15 when the FDA’s Cardiovascular and Renal Drugs Advisory Committee dives into the data for Fibrogen Inc.’s roxadustat as a treatment for anemia due to chronic kidney disease.
Following a priority review, the FDA approved Bayer AG’s Kerendia (finerenone) for chronic kidney disease (CKD) associated with type 2 diabetes (T2D). A non-steroidal mineralocorticoid receptor antagonist, Kerendia targets a key driver in CKD and has proven positive as well with regard to cardiovascular outcomes – risked especially by patients with loss of kidney function.
Diamedica Therapeutics Inc.’s chief medical officer, Harry Alcorn, said that “due to the complexity [of diabetic kidney disease (DKD)], there's not a clear answer” as to why such patients did less well in the company’s Redux phase II trial with DM-199 (recombinant human tissue kallikrein 1 [KLK1]). “But I wouldn't say that there wasn't a response in the DKD group,” he said, citing upside in 30% of subjects.
LONDON – Alentis Therapeutics SA is now equipped to deliver initial proof of concept for its universal approach to treating fibrosis, after raising $67 million in an oversubscribed series B.
PERTH, Australia – Certa Therapeutics Pty Ltd. founder and CEO Darren Kelly knows a thing or two about launching biotech companies. He spun out Fibrotech Therapeutics in 2006 from the University of Melbourne, which was one of the Medical Research Commercialization Fund’s first investments.
