Drugmaker Eli Lilly says that approval of its experimental Alzheimer’s medicine donanemab will probably be delayed past the tip of March because the US Meals and Drug Administration plans to name a last-minute assembly of its exterior advisers to overview the drug’s security and efficacy.
The medication had been anticipated to be cleared by the tip of the primary quarter of this 12 months, after being pushed again already from an anticipated approval last year. It might comply with Eisai and Biogen’s Leqembi to market because the second drug proven to gradual the course of the memory-robbing illness, which impacts greater than 6 million People. Each medication work by concentrating on plaque buildups within the mind which can be often called amyloid.
The FDA advised Lilly that it plans to name the advisory assembly to debate the protection of donanemab, in addition to the design of a key medical trial supporting its utility, known as Trailblazer-Alz 2, the corporate mentioned in a information launch Friday. The date for the assembly hasn’t been set, Lilly mentioned.
“We’re assured in donanemab’s potential to supply very significant advantages to folks with early symptomatic Alzheimer’s illness,” Lilly Neuroscience President Anne White mentioned within the launch. “It was surprising to study the FDA will convene an advisory committee at this stage within the overview course of, however we stay up for the chance to additional current the Trailblazer-Alz 2 outcomes and put donanemab’s sturdy efficacy within the context of security.”
The primary security issues with these medicines are mind swelling and micro-hemorrhages often called amyloid-related imaging abnormalities, or ARIA. In donanemab’s Part 3 medical trial, 37% of individuals had ARIA, together with three who died.
Leqembi has been tied to affected person deaths as properly, though its price of ARIA was decrease in trials.
Lilly mentioned the FDA additionally needed its exterior specialists to weigh in on the “distinctive trial design” of the donanemab examine, which allowed sufferers to cease taking the drug as soon as the amyloid plaques had been proven to be cleared from the mind. Different Alzheimer’s medication, together with Leqembi, don’t have designated stopping factors.
The trial was additionally completely different in that it separated sufferers into teams primarily based on their ranges of one other Alzheimer’s-related protein known as tau. It discovered that amongst individuals characterised as having “intermediate” ranges of tau, these taking donanemab had a 35% slower decline within the capacity to suppose clearly and carry out day by day duties in contrast with these taking a placebo.
When folks with excessive ranges of tau — who’re considered additional alongside within the illness — had been included, the profit in contrast with placebo was 22%.
Leqembi obtained full approval from the FDA in July, a call that triggered broader Medicare protection. However the drug has been off to a gradual begin, with solely about 2,000 folks taking it, Biogen mentioned on its quarterly earnings name February 13. That will mirror among the challenges of those medicines, which require plenty of scans and assessments earlier than beginning and all through remedy.
The FDA’s had a tortured historical past with latest Alzheimer’s drug approvals. It cleared a predecessor drug to Leqembi, known as Aduhelm, in 2021 in opposition to the advice of its advisory panel, and the Facilities for Medicare and Medicaid Companies limited coverage for the drug, citing an absence of proof behind it. The medication by no means took off, and Biogen discontinued it in January.
