Explained: Aducanumab, new drug for Alzheimer’s disease and row over approval
The provision of care would be constrained by the limited capacity of dementia specialists to evaluate and diagnose patients and by limited access to imaging sites to confirm the diagnosis of AD and infusion centres to deliver the treatment. Additional challenges in providing care would be issues regarding payments for treatments, regulatory changes, workforce expansion, and planning and coordination of care both at the national and local levels along with awareness campaigns. The analysis also states that no individual stakeholder will be able to coordinate the care needs of all individuals with AD. The report recommends starting timely collaborations between the stakeholders to address all obstacles in providing care to individuals with AD. Stakeholders include individuals with AD, their families and caregivers, clinicians, healthcare systems, health insurance companies, the pharmaceutical industry and various governmental agencies, amongst others.

Last month, Medicare announced one of the largest increases ever in its “Part B” monthly premium for outpatient care. It said it would raise the premium nearly $22, from $148.50 currently to $170.10 starting in January. The drugmaker said Monday that it will cut the wholesale acquisition cost of the drug by about 50% next month.
Their results have still excited neurologists, because over the years, despite heavy investments, trial after trial for Alzheimer’s medications has failed.

- Alzheimer’s disease is the most common form of dementia and contributes per cent of the cases.
- The approval of this drug without a confirmed significant clinical impact has resulted in several debates.
- Please be aware that the import of the medicines always requires customs clearance and active cooperation from the importing party.
- The report recommends starting timely collaborations between the stakeholders to address all obstacles in providing care to individuals with AD.
- It is to be noted that these trials were conducted on patients who were in the early stages of the disease,” a researcher from the Centre for Brain Research, Indian Institute of Science, Bengaluru told The Indian Express.
Perhaps aducanumab’s high price will finally provide the impetus for revisiting Medicare’s and Medicaid’s existing commitments to covering all FDA-approved drugs,” Sachs and Bagley concluded. The hallmark of Alzheimer’s disease is the accumulation of the debris caused by the breakdown of neurons in the brain, leading to plaque formation. The drug aducanumab, with brand name Aduhelm, is a monoclonal antibody that is designed to reduce the presence of amyloid beta, a protein that forms plaques in the brain. The drug is approved for use in Alzheimer disease in patients with mild cognitive impairment or mild dementia stage of the disease. In the United States, a fixed-dose combination with donepezil and memantine was approved in 2014 for the treatment of individuals with moderate to severe AD dementia who are stable on donepezil. Since AD pathogenesis is multifactorial, drugs, which act on the combination of these targets, also need to be developed [9, 54].
It was not tested in people who had progressed to moderate dementia – a state in which the patients lose the ability to care for and feed themselves. A new drug for treatment of Alzheimer’s disease holds promise, but comes with several caveats. For one thing, it is not a cure, but is aimed at slowing down cognitive decline. It is vital to obtain a brain MRI before starting aducanumab, as ARIA may develop with treatment. ARIA-E can be visualized as brain edema or sulcal effusions, and ARIA-H can be observed as microhemorrhage and superficial siderosis on brain imaging.

Clinical manifestations of ARIA were present during clinical studies in 24% of subjects who demonstrated radiographic ARIA. Symptoms include headache, confusion, delirium, altered mental status, disorientation, dizziness, vision abnormality, and nausea—the most common being headache (13%). Agents that inhibit β-site amyloid precursor protein cleaving enzyme (BACE) (lanabecestat, elenbecestat, atabecestat, and verubecestat) have also been evaluated in individuals with mild to moderate AD and prodromal AD. The trials of BACE inhibitors have also failed to show clinical significance, and a trial was stopped due to safety concerns [56]. The aducanumab saga has raged for almost 2 years, with the end perhaps still not in sight, and with time, its intricacies have grown to a level only surpassed by the pathologies and processes of the disease it treats.
Unfortunately, the Early Access Program of the manufacturer does NOT enroll patients in .
This decision of the FDA has become controversial with experts saying that clinical trials of the drug had returned unsatisfactory. Within a year, a second drug has been found effective in checking cognitive decline in people with early Alzheimer’s. Developed by the pharmaceutical giant Eli Lilly, Donanemab was found to slow down cognitive decline by 35% when compared with a placebo in a phase III trial.
How was aducanumab intended to work?
When you buy Aduhelm (aducanumab-avwa), you can make the payment by bank transfer or by credit card. When paying by credit card, you can pay online once you have received your order aducanumab price in india confirmation. Once we have received this information, one of our Patient Support Team members will then check your prescription and contact you to follow up on your order.
The inconsistencies can be linked with fewer numbers of patients in the ENGAGE trial receiving higher doses of aducanumab. Based on this finding, the ENGAGE trial protocol was amended to allow patients with APOE4 gene carriers to receive higher doses. Subgroup analysis after protocol amendment showed similar results as the EMERGE trail [46].
Based on the subject’s body weight per kilogram (kg), aducanumab should be diluted with 100 mL of 0.9% sodium chloride injection before administration as an infusion. It is also recommended the diluted https://1investing.in/ agent solution be settled at room temperature before starting therapy and should be administered without delays. Unused diluted portions after administration of aducanumab should be discarded.

Though most patient advocates are pleased with the hope of having a new drug to treat AD, the approval of aducanumab creates unnecessary uncertainties for patients, clinicians, and researchers. The European Medicines Agency has recently voted against the approval of aducanumab for use in European countries. In this review, evidence from clinical trials of aducanumab, implications of aducanumab approval, and future directions in the management of patients with Alzheimer’s disease are discussed.
However, the inconsistent results observed with aducanumab may be explained by the limited brain penetration and lack of selectivity for the soluble Aβ-oligomers, which are implicated as upstream drivers of neurodegeneration by multiple studies [48]. The most common adverse events reported within these two studies were ARIA, headache, diarrhea, and fall. ARIA-E was reported in 34% and 35.5% of patients who received high-dose aducanumab in EMERGE and ENGAGE, respectively. Both trials had patients with an average age of 70 years and included patients with APOE gene carriers and noncarriers. The trial used a clinical dementia rating scale to evaluate the impact of taking the drug in delaying the progression of the disease. The ENGAGE trial and EMERGE trials were terminated before completion due to lack of benefit based on data of the early 1748 patients in March 2019.
Until recently, all approved treatments for AD were symptomatic and not disease modifying. On 7 June 2021, the US FDA approved aducanumab, a human IgG1 anti-Aβ monoclonal antibody selective for Aβ aggregates, as the first disease-modifying treatment for AD. Aducanumab is approved in the United States for the treatment of mild cognitive impairment or mild-dementia stage of AD. In this Editorial, we review the trial data for aducanumab in the treatment of AD and the controversies that its approval has generated.
