Alzheimer’s disease, a progressive neurodegenerative condition, robs patients of their memories, movement, and independence. While there is currently no cure, recent developments in the medical field offer a glimmer of hope. Eli Lilly’s investigative drug, Donanemab for Alzheimer treatment, has shown encouraging results in clinical trials, raising expectations for its potential approval and impact on Alzheimer’s treatment.
About Eli Lilly
Established in 1876 by Colonel Eli Lilly, a man with the mission of creating reliable and high-quality medicines for those in need. His motto for his employees was “Take what you find here and make it better and better,” after 145 years, all the employees in this company still follow his commitment with the same dedication. They are well known for their recently released new drug ‘Zepbound’ for Obesity to help diabetic patients improve their lives.
Positive Phase 3 Trial Results of Donanemab
In May 2023, Eli Lilly announced positive findings from the TRAILBLAZER-ALZ 2 Phase 3 study evaluating Donanemab’s efficacy in early-stage Alzheimer’s patients. The study, involving over 1,800 participants, demonstrated significant benefits like:
- Slowed cognitive decline in the patients. Compared to a placebo, Donanemab treatment slowed cognitive decline by 35% as measured by the integrated Alzheimer’s Disease Rating Scale (iADRS), a key metric assessing both cognitive function and daily living activities.
- It showed Improved daily functioning in Patients after receiving Donanemab, a 40% reduction in decline on measures of daily living activities, allowing them to maintain independence for longer.
- The high completion rate of Donanemab makes it magical. Over half of the participants completed the 18-month treatment course, suggesting tolerability and adherence.
Next Steps and Regulatory Approvals
Eli Lilly promptly submitted a traditional New Drug Application (NDA) to the US Food and Drug Administration (FDA) upon these promising results. However, the path to approval could be more straightforward than they thought it would be.
- The FDA has heightened inspection and approval of Alzheimer’s drugs after the controversial approval and subsequent commercial failure of Aduhelm in 2021. Donanemab will likely face a strict review process demanding strong evidence of clinical benefit and safety.
- Donanemab isn’t alone in the race for Alzheimer’s treatment drugs. Leqembi, a similar drug developed by Eisai and Biogen, received FDA approval in January 2023, setting a path for Donanemab’s approval process.

Expert Opinions on Donanemab for Alzheimer Treatment
While awaiting a regulatory decision, experts cautiously weigh the potential of Donanemab:
- Dr. Maria Carrillo, Alzheimer’s Association Chief Science Officer: “These [trial] results are encouraging, but we need to see the full data and await FDA review before drawing definitive conclusions.”
- Dr. Jeffrey Cummings, Cleveland Clinic Lou Ruvo Center for Brain Health: “Donanemab’s data is impressive, but the question remains, will it be enough for FDA approval?”
The Future Implications of Donanemab
The potential approval of Donanemab carries significant implications for the future:
- Hope for Patients: If approved, Donanemab could offer a much-needed treatment option for early-stage Alzheimer’s patients and give them hope, potentially slowing disease progression and improving quality of life.
- Impact on Pharmaceutical Landscape: A successful approval could support confidence in Alzheimer’s research and development, encouraging further investment and innovation in this field for the researchers.
- Addressing Societal Impact: Alzheimer’s disease contains a tremendous social and economic burden. Effective treatments could alleviate this burden on families, healthcare systems, and society.
The potential approval of Donanemab represents a crucial step in the fight against Alzheimer’s disease. While uncertainties remain regarding its regulatory journey, the positive clinical trial results of Donanemab for Alzheimer treatment offer a ray of hope for patients and the scientific community. However, it’s important to remember that approval depends on a thorough and rigorous review process, ensuring the drug’s safety and efficacy before it reaches patients in need.
