Pfizer Inc.’s Beqvez (fidanacogene elaparvovec) won FDA approval for use in adults with hemophilia B, making it the second adeno-associated viral (AAV) vector-based gene therapy available for patients in the U.S., following the late 2022 approval of CSL Behring’s Hemgenix (etranacogene dezaparvovec).
An oral Bruton’s tyrosine kinase (BTK) inhibitor that Sanofi SA acquired in 2020 through its $3.68 billion buyout of Principia Biopharma Inc. is headed toward regulatory filings in the U.S and EU by the end of the year, following phase III data in immune thrombocytopenia.
Agios Pharmaceuticals Inc.’s fourth-quarter and full-year 2023 financial report in mid-February highlighted further prospects with Pyrukynd (mitapivat), the pyruvate kinase activator for hemolytic anemia in adults with pyruvate kinase deficiency (PKD).
Some gene therapies could be big winners under the changes the U.S. Centers for Medicare & Medicaid Services (CMS) is proposing to Medicare’s new technology add-on program (NTAP) for its fiscal 2025 inpatient prospective payment system.
With a $128 million series A financing, Diagonal Therapeutics Inc. launched to develop its lead program using agonist antibodies for treating, among other indications, the rare disease hereditary hemorrhagic telangiectasia.

Diagonal also is developing a treatment for the orphan disease pulmonary arterial hypertension.
Disc Medicine Inc. CEO John Quisel said that top-line phase II findings from the study called Aurora with bitopertin in erythropoietic protoporphyria are “hard for us to interpret.

Voydeya (danicopan), from Alexion, Astrazeneca Rare Disease, racked up its second global approval as the U.S. FDA greenlit it as an add-on therapy for treating extravascular hemolysis in adults with paroxysmal nocturnal hemoglobinuria (PNH), a crowded market with several already approved treatments and more in development.
The EMA’s Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion recommending approval of Pfizer Inc.’s Emblaveo (aztreonam-avibactam), an antibiotic combination that would offer a new option to patients with serious bacterial infections caused by multidrug-resistant gram-negative bacteria. If approved, Emblaveo would be among the first beta-lactam/beta-lactamase inhibitor combos cleared for use in Europe.
After hearing two conflicting presentations of the safety and efficacy of Geron Corp.’s imetelstat, the U.S. FDA’s Oncology Drugs Advisory Committee (ODAC) voted 12-2 March 14 that the drug’s benefit outweighed its risks as a treatment for transfusion-dependent anemia in adults with low- to intermediate-1 risk myelodysplastic syndromes in patients who have failed or no longer respond to erythropoiesis stimulating agents (ESAs), or who are not eligible for ESA treatment.
Although Geron Corp.’s imetelstat met its primary and key secondary endpoints in a phase III study, the U.S. FDA is questioning the magnitude and durability of the effect of the first-in-class telomerase inhibitor as a second-line treatment of transfusion-dependent anemia in adults with low- to intermediate-1 risk myelodysplastic syndromes. The agency’s concerns resulted in more than an 12% stock tumble March 12 after the FDA released its briefing document two days ahead of an Oncology Drugs Advisory Committee meeting, in which the panel will be asked to vote on whether imetelstat’s benefits outweigh its risks.
