It looks like Biogen Inc.’s Nrf2 activator, Skyclarys (omaveloxolone), will maintain its status as the sole therapy approved for treating patients with Friedreich’s ataxia (FA), at least for now. The U.S. FDA asked for another “adequate and well-controlled study” in the complete response letter (CRL) issued to PTC Therapeutics Inc. for 15-lipoxygenase inhibitor vatiquinone. The agency said “substantial evidence of efficacy was not demonstrated.”
The first bispecific antibody to win regulatory approval is about to make a comeback 10 years after being taken off the market in Europe for commercial reasons. Catumaxomab, then called Removab, and now reborn with the brand name Korjuny, received a positive opinion for the treatment of malignant ascites from the EMA’s Committee for Medicinal Products for Human Use (CHMP,) at its monthly meeting Oct. 14 to 17.
The EMA’s Committee for Medicinal Products for Human Use (CHMP) recommended approval of 14 drugs and the extension of the label of 11 others at its July meeting, but, inevitably, it was the decision to turn down the Alzheimer’s disease therapy Leqembi (lecanemab) that stirred the greatest reaction.
Two drugs were pushed back by the EMA last week, with a recommendation that Ocaliva, currently the only second line standard of care for treating primary biliary cholangitis, be withdrawn from the market, and a refusal to grant conditional approval for masitinib in the treatment of amyotrophic lateral sclerosis.
The EMA has been sent back to the drawing board to re-evaluate PTC Therapeutics Inc.’s Duchenne muscular dystrophy therapy Translarna (ataluren), after failing to get the usual rubber stamp following its recommendation in January that the drug’s conditional approval be withdrawn.
After almost 10 years on the market, the EMA is to withdraw its conditional approval of the Duchenne muscular dystrophy treatment Translarna (ataluren), after concluding there is still not enough evidence of its effectiveness.
“This is a tough business. It’s never a straight line from start to success.” Those words, from Exelixis Inc. CEO Michael Morrissey, during a presentation at the J.P. Morgan Healthcare Conference (JPM), could easily sum up any aspect of the biopharma industry. But with more biopharma firms than ever having reached commercial status, along with the introduction of new therapeutic modalities into the health care market, many are finding the toughest part comes after regulatory approval, whether it’s navigating a competitive landscape, getting payers and physicians on board, or satisfying regulators’ stringent postmarketing requirements. As industry players and observers head home after a busy week in San Francisco, BioWorld offers a brief glimpse at a few firms taking on those post-approval challenges in 2024.
“We’re going to battle,” PTC Therapeutics Inc. CEO Matthew Klein said, responding to a surprise negative opinion from the EMA’s Committee for Medicinal Products for Human Use on converting the conditional marketing authorization to full status for Translarna (ataluren) in the treatment of nonsense mutation Duchenne muscular dystrophy. The opinion applies to the renewal of the existing conditional authorization, too.
After an up-and-down day – mostly up, toward the end – during which the phrase “totality of the data” got air time aplenty, shares of PTC Therapeutics Inc. (NASDAQ:PTCT) closed at $34.07, a rise of $5.66, or almost 20%, on word of top-line data from Study 041 with Translarna (ataluren) in nonsense mutation Duchenne muscular dystrophy (DMD).
In the wake of Study 045’s failure with Translarna (ataluren) in nonsense mutation Duchenne muscular dystrophy, PTC Therapeutics Inc. is “trying to thread the needle between the notion of getting Study 041 completed in the third quarter of 2022 vs. getting accelerated approval now,” CEO Stuart Peltz said.
