In a release, Apellis noted that there were “multiple dissenting votes” by CHMP members to the opinion. The company added that it plans to seek a reexamination of the opinion, with a final decision expected in the fourth quarter of this year.
“Although the studies showed that Syfovre slowed the growth of geographic atrophy lesions, this did not lead to clinically meaningful benefits for patients,” the CHMP said. “It was noted that benefits of a treatment should impact patients’ everyday functioning, and this was not demonstrated in the studies.”
“In terms of safety,” the CHMP continued, “regular injections into the eye carry a significant risk of adverse events, including the development of other forms of AMD or inflammation in the eye, that could further worsen vision.”
In January of this year, the CHMP adopted its first negative opinion on Syfovre. The drug was approved by the FDA in February of 2023 and generated $275 million in sales last year despite early reports of inflammation for some users.
In May, the company said that it holds an 85% share of the market in GA, but admitted to challenges with its launch. In the indication, Apellis is competing with Astellas’ Izervay, which has filed for approval in Europe.
Mizuho Securities analyst Graig Suvannavejh noted that there was a 5% drop in Apellis' share price on Friday morning.
"There have yet to be data convincingly demonstrating Syfovre use leading to clear, clinically meaningful functional benefit," Suvannavejh wrote in a note to clients. "Moreover, from a drug approval perspective, we view the European Medicines Agency as typically more conservative than the FDA. As such, we lower our probability of success for Syfovre's EU approval from 20% to 10%."
Other CHMP rejections
Syfovre was not the only drug that was beaten back by the CHMP more than once. The European drug reviewers have once again recommended not renewing the marketing authorization for PTC TherapeuticsPTC Therapeutics’ Translarna as a treatment for Duchenne muscular dystrophy.
This negative opinion follows the European Commission’s May decision to not adopt the CHMP’s negative opinion from January. By that time, The CHMP had already reviewed and declined to renew the drug’s conditional nod twice.
According to PTC, the scientific advisory group convened for the latest review concluded that the evidence of significant efficacy provided by the STRIDE trial "should not be ignored." And yet, the agency still maintained its previous stance.
Now, PTC plans to request a reexamination of the CHMP’s third opinion. After that, the European Commission will make a decision. Based on the timeline of these procedures, PTC said it expects Translarna to remain on the market through the end of 2024 even if the negative opinion holds.
Meanwhile, the CHMP this week issued positive recommendations for several therapies, including Merck’s blockbuster-to-be Winrevair for pulmonary arterial hypertension (PAH). Winrevair, which gained a high-profile approval from the FDA in March, is the first disease-modifying treatment for the condition.
Winrevair, which was acquired by Merck in an $11.5 billion buyout of Acceleron in 2021, has been pegged by J.P Morgan analyst Chris Schott to achieve peak sales between $3 billion and $4 billion.
ARS expects to receive authorization from the EU in the third quarter and to launch Eurneffy in the fourth quarter. The company also hopes for approval of the product from the FDA, with a decision date set for October 2 of this year.
Moderna’s respiratory syncytial virus (RSV) vaccine mRasvia has made the grade with the CHMP, too, gaining a recommendation for adults ages 60 and older. The shot, which was approved by the FDA four weeks ago, is the first mRNA vaccine targeting a pathogen other than the coronavirus to receive a positive opinion from the CHMP.
Regeneron’s CD20xCD3 bispecific T-cell engager Ordspono (odronestamab) netted a positive opinion from the CHMP to treat two types of blood cancers—follicular lymphoma and diffuse large B-cell lymphoma. The thumbs up comes three months after the FDA sent two complete response letters to Regeneron for the same indications, questioning the timelines of the company’s confirmatory trials.
The CHMP recommended Roche’s Piasky (crovalimab) for marketing authorization, just four days after the FDA endorsed it for patients age 13 and older with paroxysmal nocturnal hemoglobinuria (PNH), a rare, genetic life-threatening disorder of the immune system that causes premature breakdown of the red blood cells.
The CHMP also has issued a positive opinion on EliLilly’s Tauvid (flortaucipir), the first drug used to image a characteristic of Alzheimer’s disease in the brain called tau pathology. The FDA signed off on Tauvid four weeks ago.
