Lilly’s Kisunla Gains Marketing Authorization in Great Britain for Alzheimer’s Treatment in Select Adult Patients

Eli Lilly and Company announced that the Medicines and Healthcare products Regulatory Agency (MHRA) has granted marketing authorization for donanemab, an injection for intravenous infusion every four weeks to treat mild cognitive impairment and mild dementia due to Alzheimer’s disease in eligible adults in Great Britain. Eligible patients are limited to apolipoprotein E ε4 (ApoE ε4) heterozygotes or non-carriers, which is a requirement for the class of currently approved amyloid-targeting therapies in Great Britain. Donanemab is the only amyloid plaque-targeting therapy with evidence to support stopping therapy when amyloid plaques are removed. Great Britain is the third major market to approve donanemab, marketed as Kisunla.

“People around the world want and deserve access to treatment options for this disease. This approval in Great Britain is another significant step to ensure patients with Alzheimer’s disease can receive treatment with this new class of amyloid targeting therapies, which could give them more time in the early symptomatic stage of the disease to do what matters most to them,” said Ilya Yuffa, executive vice president and president of Lilly International, Eli Lilly and Company. “Donanemab demonstrated meaningful results for people with early symptomatic Alzheimer’s disease by significantly slowing cognitive and functional decline in our TRAILBLAZER-ALZ 2 study.”

Currently, there are 982,000 people estimated to be living with dementia in the United Kingdom (UK), with 50-75% of cases attributable to Alzheimer’s disease. It is the leading cause of death in the UK and an economic cost to society. The total cost of dementia on patients, families and the public sector is estimated to be £42 billion in 2024. Unpaid care is the largest component, with costs per person increasing threefold from mild to severe dementia.

Amyloid is a protein produced naturally in the body that can clump together to create amyloid plaques. The excessive buildup of amyloid plaques in the brain may lead to memory and thinking issues associated with Alzheimer’s disease.  Donanemab can help the body remove the excessive buildup of amyloid plaques and slow the cognitive and functional decline that may diminish people’s ability to remember information, make meals, manage finances, and maintain independence.

“I believe we can improve the standard of care for people living with Alzheimer’s disease. Despite years of medical research, until recently, there has been little progress in treatment options for this disease. The authorisation of donanemab for eligible adults is welcome news. Great Britain now needs to rapidly increase National Health Service (NHS) capacity and expertise in diagnostics and treatment facilities to enhance the management of Alzheimer’s disease for the benefit of people today and tomorrow,” said Professor Cath Mummery, Consultant Neurologist at University College London Hospitals NHS Foundation Trust and Chair of the NIHR Dementia Translational Research Collaboration.
