The good news for Sarepta Therapeutics Inc. is bad news for Pfizer Inc. as the phase III study of its mini-dystrophin gene therapy in Duchenne muscular dystrophy has missed its primary endpoint. Now Sarepta’ s Elevidys (delandistrogene moxeparvovec-rokl), a single-dose, adeno-associated virus-based gene transfer therapy, is barrelling toward a June 21 PDUFA date with the U.S. FDA as the near competition shrinks in the rearview mirror. Pfizer’s fordadistrogene movaparvovec failed to hit the mark on motor-function movement in ambulatory boys ages 4 to 7 when compared to placebo. It's another blow to Pfizer as about six weeks ago a boy in its phase II Daylight study of Duchenne died after receiving the same gene therapy.
Urogen soars on duration of response data in bladder cancer
Urogen Pharma Ltd. shares (NASDAQ:URGN) were trading at $17.90, up $5.18, or 40%, on word of an 82.3% (95% CI, 75.9%, 87.1%) 12-month duration of response data by Kaplan-Meier estimate (n=108) from its phase III Envision study.

Itch takes a powder as Cara scratches difelikefalin
Following a phase II/III failure, Stamford, Conn.-based Cara Therapeutics Inc. discontinued its only pipeline program, that of oral difelikefalin for moderate to severe pruritis in adults with notalgia paresthetica, placing the company’s future in question. While the intravenous version of the first-in-class kappa opioid receptor agonist gained U.S. FDA approval under the brand name Korsuva in August 2021 for pruritis in patients undergoing hemodialysis, sales coming to Cara are meager compared to the company’s expenses. For 2023, Cara recorded a net loss of $118.5 million, which accounted for $108.5 million in R&D expenses and $21 million in total revenue – including $12.9 million in Korsuva profit-share revenue from partner CSL Vifor. “Given no obvious value drivers from here … we downgrade Cara to a neutral rating with no price target,” said H.C. Wainwright analyst Oren Livnat. Cara’s shares (NASDAQ:CARA) plunged 36% to 43 cents in early trading June 13.

Biosecure Act misses first congressional ride
While the Biosecure Act missed its first chance at a congressional ride, that doesn’t mean it will be stranded by the wayside. Although it enjoyed strong bipartisan support, the bill wasn’t included as a rider to the U.S. House version of the National Defense Authorization Act, a must-pass defense spending bill for fiscal 2025. However, there’s still significant momentum to pass the bill, possibly as an add-on to the Senate version of the defense spending bill, as stand-alone legislation or as part of an end-of-year health legislative package, RBC Capital Markets LLC analyst Leonid Timashev noted.
Supremes shoot down abortion pill challenge
The U.S. Supreme Court today unanimously upheld the FDA’s relaxed regulation of the abortion drug mifepristone when it ruled that the organizations challenging those changes lacked the standing to do so. “A plaintiff’s desire to make a drug less available for others does not establish standing to sue,” Justice Brett Kavanaugh wrote for the court. While Justice Clarence Thomas agreed with the rest of the court, he issued a concurring opinion to express his concerns about the expansion of associational standing over the years. He encouraged the court to “explain just how the Constitution permits associational standing” when an appropriate case arises.
