Lilly's Kisunla (donanemab) receives marketing authorization by European Commission for the treatment of early symptomatic Alzheimer's disease |

Approved for earliest symptomatic stages of disease, demonstrating significant slowing of cognitive and functional decline Only therapy with evidence to support completing course of treatment once amyloid plaques are reduced to minimal levels INDIANAPOLIS, Sept. 25, 2025 /PRNewswire/ -- Eli Lilly and Company (NYSE: LLY) announced today that the European Commission (EC) has granted marketing authorization for Kisunla (donanemab) for the treatment of early symptomatic Alzheimer's disease (AD), in adults with mild cognitive impairment as well as those with mild dementia stages of AD with confirmed amyloid pathology who are apolipoprotein E (ApoE4) heterozygotes or non-carriers. "Kisunla demonstrated meaningful results in people with early symptomatic Alzheimer's disease by significantly slowing cognitive and functional decline in our Phase 3 TRAILBLAZER-ALZ 2 study," said Patrik Jonsson, executive vice president and president of Lilly International. "The data shows that the earlier patients are identified, diagnosed, and treated with Kisunla, the greater the response to treatment. This authorization brings a new option to patients in Europe—offering hope and the potential for more time to focus on what matters most." Amyloid is a protein produced naturally in the body that can clump together to create amyloid plaques.1,2 The excessive buildup of amyloid plaques in the brain may lead to memory and thinking issues associated with Alzheimer's disease. Kisunla can help the body remove the excessive buildup of amyloid plaques and slow the decline that may diminish people's ability to: remember new information, important dates and appointments; plan and organize; make meals; use household appliances; manage finances; and be left alone.1-3 Kisunla is the only once-monthly amyloid plaque-targeting therapy with evidence supporting completing course of treatment once amyloid is reduced to minimal levels. This may reduce infusion burden and treatment costs. Treatment with Kisunla slows disease progression which may help preserve cognitive function and independence longer.4-7 Data has also shown that Kisunla can significantly reduce the risk of progressing to the next clinical stage of disease over 18 months.4,8 Alzheimer's disease currently affects as many as 6.9 million people in Europe, with this figure expected to almost double by 2050 as aging populations continue to increase.9,10 Alzheimer's disease progresses in stages that increase in severity over time, resulting in loss of independence and ability to care for oneself. There is an urgent need for detection, referral to specialists, diagnosis and treatment at the earliest stages of Alzheimer's disease as approximately one-third of individuals in early symptomatic stages of the disease will progress to more advanced clinical stages within one year.11 The Kisunla marketing authorization in the European Union is based on the TRAILBLAZER-ALZ 2 and the TRAILBLAZER-ALZ 6 clinical trials. The Phase 3 TRAILBLAZER-ALZ 2 study demonstrated Kisunla significantly slowed cognitive and functional decline.4,8 Cognitive and functional decline involves greater memory and thinking problems, affecting daily activities and needing more caregiver support.4,12 Amyloid-related imaging abnormalities (ARIA) with edema/effusion (ARIA-E) and with hemorrhage/ hemosiderosis (ARIA-H) are side effects within the class of therapies that do not usually cause any symptoms, but serious and life-threatening symptoms can occur. ARIA can be fatal. Carriers of one or two copies of the ApoE4 gene may be at higher risk of developing Alzheimer's disease and experiencing ARIA. Patients should discuss any safety concerns with their healthcare providers. The dosing schedule is based on the Phase 3b TRAILBLAZER-ALZ 6 study, which demonstrated that the incidence of ARIA-E was significantly lowered at 24 and 52 weeks using a more gradual titration dosing schedule versus the dosing schedule used in TRAILBLAZER-ALZ 2. This gradual dosing increase still achieved similar levels of amyloid plaque removal and P-tau217 reduction.8 About Kisunla *Donanemab is branded as Lormalzi in Singapore About TRAILBLAZER-ALZ 2 About TRAILBLAZER-ALZ 6 study and the TRAILBLAZER-ALZ program Lilly continues to study donanemab in multiple clinical trials, including TRAILBLAZER-ALZ 3, which is evaluating the safety and efficacy of donanemab in patients with preclinical Alzheimer's disease (Stage 1 and 2) to determine if it reduces risk of progression to symptomatic Alzheimer's disease. TRAILBLAZER-ALZ 5 is a registration trial for early symptomatic Alzheimer's disease currently enrolling in China, Korea, Taiwan, and other geographies. U.S. INDICATION AND SAFETY SUMMARY WITH WARNINGS Kisunla (donanemab-azbt), pronounced kih-SUHN-lah, is used to treat adults with early symptomatic Alzheimer's disease (AD), which includes mild cognitive impairment (MCI) or mild dementia stage of disease. Warnings - Kisunla can cause Amyloid-Related Imaging Abnormalities or "ARIA." This is a common side effect that does not usually cause any symptoms, but serious symptoms can occur. ARIA can be fatal. ARIA is most commonly seen as temporary swelling in an area or areas of the brain that usually goes away over time. Some people may also have spots of bleeding on the surface of or in the brain and infrequently, larger areas of bleeding in the brain can occur. Although most people do not have symptoms, some people have headaches, dizziness, nausea, difficulty walking, confusion, vision changes and seizures. Some people have a genetic risk factor (homozygous apolipoprotein E ε4 gene carriers) that may cause an increased risk for ARIA. Talk to your healthcare provider about testing to see if you have this risk factor. You may be at higher risk of developing bleeding in the brain if you take medicines to reduce blood clots from forming (antithrombotic medicines) while receiving Kisunla. Talk to your healthcare provider to see if you are on any medicines that increase this risk. Your healthcare provider will do magnetic resonance imaging (MRI) brain scans before and during your treatment with Kisunla to check you for ARIA. You should carry information that you are receiving Kisunla, which can cause ARIA, and that ARIA symptoms can look like stroke symptoms. Call your healthcare provider or go to the nearest hospital emergency room right away if you have any of the symptoms listed above. There are registries that collect information on treatments for Alzheimer's disease. Your healthcare provider can help you become enrolled in these registries. Warnings - Kisunla can cause serious allergic and infusion-related reactions. Do not receive Kisunla if you have serious allergic reactions to donanemab-azbt or any of the ingredients in Kisunla. Symptoms may include swelling of the face, lips, mouth, or eyelids, problems breathing, hives, chills, irritation of skin, nausea, vomiting, sweating, headache, or chest pain. You will be monitored for at least 30 minutes after you receive Kisunla for any reaction. Tell your healthcare provider right away if you have these symptoms or any reaction during or after a Kisunla infusion. Other common side effects
Tell your healthcare provider right away if you have any side effects. These are not all of the possible side effects of Kisunla. You can report side effects at 1-800-FDA-1088 or www.fda.gov/medwatch. Before you receive Kisunla, tell your healthcare provider:
