While the 12-month data from Bridgebio Pharma Inc.’s phase III ATTRibute-CM study testing acoramidis in transthyretin amyloid cardiomyopathy were deemed “puzzling” in late 2021, the 30-month results reported July 17 proved far more pleasing to investors. The trial hit all its endpoints and showed promising results on exploratory markers, sending company shares (NASDAQ:BBIO) up 76%, to close at $32.04, up $13.82.

Although Pfizer Inc. has the only drugs approved in the U.S. to treat a rare, progressive heart disease, the U.S. Court of Appeals for the Second Circuit agreed this week with the Department of Health and Human Services, and a lower court, that Pfizer’s proposed copay assistance program for middle-income Americans covered by Medicare would violate the federal Anti-Kickback Statute – even if the company has no “corrupt” intent.

Astrazeneca plc’s recently acquired Alexion Pharmaceuticals Inc. has signed a deal worth up to $760 million with Neurimmune AG, the Swiss biotech that discovered Alzheimer’s drug Aduhelm (aducanumab), buying rights to amyloidosis drug NI-006. While Biogen Inc.’s Aduhelm targets amyloid plaques thought to cause Alzheimer’s in the brain, the phase Ib drug in Alexion’s deal is intended to tackle the build-up of the rogue protein that causes heart disease caused by transthyretin amyloid cardiomyopathy (ATTR-CM).

Top-line results from Bridgebio Pharma Inc.’s ongoing phase III study of acoramidis are no holiday gift for the company. The clinical trial for treating symptomatic transthyretin amyloid cardiomyopathy missed its primary endpoint. The Palo Alto, Calif.-based company’s stock (NASDAQ:BBIO) plunged on the news as shares closed 72% lower Dec. 27 at $11.38 each.

Citing the First Amendment, the Fifth Amendment and the logic of fair play, Pfizer Inc. is taking on a Health and Human Services’ (HHS) antitrust policy that prohibits drug companies from helping Medicare beneficiaries with hefty copays.
