The major players in electrophysiology – Boston Scientific Corp., Johnson & Johnson, Medtronic plc, Abbot Laboratories – showed up in force at the 2024 Heart Rhythm Society annual meeting in Boston May 16-19 to tout their pulsed field ablation devices and study results.

Shares of Dyne Therapeutics Inc. (NASDAQ:DYN) closed May 20 at $35.38, up $7.70, or 28%, on word of positive data from the phase I/II Achieve trial of DYNE-101 in myotonic dystrophy type 1 (DM1) and the phase I/II Deliver effort with DYNE-251 in Duchenne muscular dystrophy (DMD) who are amenable to exon 51 skipping. CEO John Cox, who joined Waltham, Mass.-based Dyne eight weeks ago, said he “couldn’t be more proud to be part of this team.” Studies are ongoing, but new data with regard to DM1 as well as DMD showed a “compelling” impact, Dyne said, plus satisfying safety profiles.

U.S. Medicare coverage of transcatheter aortic valve replacement devices requires the use of team medicine for patient selection purposes, which seems to have served as a tripwire for Cape Cod Hospital (CCH) in Hyannis, Mass. Federal agencies forged an agreement with CCH that included a $24 million fine for failure to appropriately screen patients for the procedure, an event that serves as a reminder that non-compliance with Medicare rules can trigger enforcement actions by other agencies.

Pulsed field ablation dominated the news out of the Heart Rhythm Society meeting this week with three late-breaking studies highlighting the safety and efficacy of the technology replacing thermal ablation for treatment of atrial fibrillation and active discussion of the ‘unprecedented’ growth of these procedures. Boston Scientific Corp’s Farapulse is rapidly building dominance in the field, while results from Johnson & Johnson’s Varipulse study and Medtronic plc’s trial of the Affera system set up those companies for U.S. FDA approval later this year.

The U.S. FDA has several methods for signaling its enforcement intentions regarding medical devices and drugs, but there are times when warning letters are the vectors for communicating the agency’s current thinking.

The U.S. FDA is not the only regulatory agency attempting to deal with impending and existing device and drug shortages, although some of the drivers of these shortages are not within these agencies’ purview.

In April, the U.S. FDA approved 26 new drugs, the sixth-highest monthly total going back to 2016. This is slightly lower than March’s record-setting 30 approvals, the highest count in BioWorld’s records. By comparison, the FDA approved an average of about 16 drugs per month in 2023, 12.5 per month in 2022, and 17 per month in both 2021 and 2020.

A new horizon may be opening up in low-grade serious ovarian cancer (LGSOC) with the advent of Verastem Oncology Inc.’s therapy pairing two small molecules: avutometinib (VS-6766), a kinase inhibitor that binds to and inhibits the kinase activities of RAF and MEK to block the signal transduction pathways they mediate; and defactinib (VS-6063), an inhibitor of FAK.

The U.S. FDA granted accelerated approval to Amgen Inc.’s Imdelltra (tarlatamab) for treating adults with extensive-stage small-cell lung cancer with disease progression on or after platinum-based chemotherapy. The approval may well lead the drug to blockbuster status while bolstering the company’s cancer portfolio.
