Assessing the benefits of decentralized clinical trials in Alzheimer’s research

### Assessing the Benefits of Decentralized Clinical Trials in Alzheimer’s Research

Alzheimer’s disease is a complex condition that affects millions of people worldwide. Researchers are working tirelessly to find new treatments and improve diagnosis. One innovative approach in Alzheimer’s research is the use of decentralized clinical trials. In this article, we will explore the benefits of decentralized clinical trials and how they are transforming the way we study Alzheimer’s.

#### What Are Decentralized Clinical Trials?

Decentralized clinical trials are studies that take place outside traditional research facilities. Instead of patients traveling to a single location for testing, assessments and monitoring can be done remotely using digital solutions and telemedicine. This approach aims to remove barriers to clinical trial participation by making it easier for patients to engage in research from the comfort of their own homes or local community facilities.

#### How Do Decentralized Trials Work?

In Alzheimer’s research, decentralized trials use a variety of technologies to conduct assessments and monitoring. For example, video calls and tablet computers are used to conduct cognitive tests and monitor patients’ progress. Blood draws, MRIs, and other medical procedures are often done at local facilities, reducing the need for patients to travel long distances.

The Mayo Clinic is at the forefront of this innovation. Their Clinical Trials Beyond Walls program allows patients to complete some or all of their assessments from home. This not only makes the process more convenient but also helps to engage a more diverse group of participants, which is crucial for understanding the disease better[1].

#### Benefits of Decentralized Trials

1. **Increased Participation**: By making trials more accessible, decentralized studies can attract a broader range of participants. This is particularly important in Alzheimer’s research, where diverse populations are essential for understanding the disease’s impact on different groups.

2. **Improved Patient Experience**: Remote participation reduces the burden on patients, allowing them to continue their daily routines while still contributing to research. This can lead to higher patient satisfaction and better adherence to trial protocols.

3. **Enhanced Data Collection**: With the ability to collect data continuously, researchers can gain a more comprehensive understanding of the disease’s progression. This real-time data can also help in identifying potential biomarkers and disease-modifying targets more effectively.

4. **Cost Efficiency**: Decentralized trials can reduce costs associated with travel and facility maintenance. These savings can be reinvested in the research, potentially leading to more extensive and detailed studies.

5. **Faster Results**: By leveraging digital solutions, researchers can process data faster, leading to quicker results and potentially faster development of new treatments.

#### Examples in Alzheimer’s Research

Lilly is another company actively using decentralized trials in Alzheimer’s research. Their TRAILBLAZER-ALZ 2 trial, for instance, involves participants receiving either donanemab or a placebo. Assessments and monitoring are conducted remotely using video calls and tablet computers, while drug infusions and MRIs are done at local facilities[4].

The success of these trials is evident in the positive top-line results from the TRAILBLAZER-ALZ 2 study. Donanemab significantly slowed cognitive decline in participants, with benefits greatest for those with mild cognitive impairment. Although some participants experienced adverse effects like ARIA (amyloid-related imaging abnormalities), the overall safety and efficacy of the treatment were promising[4].

#### Conclusion

Decentralized clinical trials are revolutionizing Alzheimer’s research by making it more accessible, convenient, and efficient. By leveraging digital technologies and remote services, these trials can attract a wider range of participants, improve patient experience, and enhance data collection. The success of decentralized trials in Alzheimer’s research is a significant step towards finding better treatments and improving outcomes for those affected by this devastating disease.

As research continues to evolve, it is clear that decentralized clinical trials will play a crucial role in advancing our understanding of Alzheimer’s and developing effective treatments.
