Novo Nordisk A/S reported top-line results from the phase III Hibiscus study of its pyruvate kinase-R activator, etavopivat, which was acquired through the 2022 buyout of Forma Therapeutics Holdings Inc. The results set up a potential competition for patients afflicted by sickle cell disease with fellow PKR activator mitapivat from Agios Pharmaceuticals Inc.

After reaching their peaks in late November, both the BioWorld Drug Developers Index and the Nasdaq Biotechnology Index finished the year slightly down from those highs.

“Our goal is that by the end of this call, you’ll share our conviction in the totality of the data.” So said Agios Pharmaceuticals Inc. CEO Brian Goff as the company reported top-line data from its 52-week Rise Up trial testing mitapivat in sickle cell disease showing the oral pyruvate kinase activator hit statistical significance on one of two primary endpoints and two of three key secondary endpoints.

Word Sept. 4 from Agios Pharmaceuticals Inc. that the U.S. FDA extended the PDUFA date for the sNDA related to Pyrukynd (mitapivat), after the Cambridge, Mass.-based firm submitted a proposed risk evaluation and mitigation strategy (REMS), drew Wall Street’s attention to the regulatory approach.

Agios Pharmaceuticals Inc. said the patients’ deaths tied to anemia therapy Pyrukynd (mitapivat) that were announced in a securities analyst’s Aug. 4 note to investors hasn’t changed the drug’s already established benefit-risk profile on the drug’s U.S. prescribing information.

Agios Pharmaceuticals Inc. is learning the hard way the downside of having a pipeline in a product. When a side effect crops up, investors are likely to worry that it may affect the potential of the drug in the numerous diseases the drug could potentially treat.
