About The Precision
Medicine Program

The Precision Medicine Program (PMP) is the most comprehensive and longest running translational research study in amyotrophic lateral sclerosis (ALS). Through this collaborative study, ALS TDI partners with people living with ALS all over the world to gather data about the progression of ALS and advance our ALS drug discovery. Participants share their data on movement, lifestyle, medical history, genetics, biomarkers, voice recordings and patient cell biology.

Here's how PMP data helps to advance ALS research at ALS TDI:

  1. Discovering Drug Targets: We study participant data to find new drug targets and identify the ALS populations for which they are most relevant.
  2. Identifying Promising Drugs: We test potential ALS treatments on iPS cell models that were developed from PMP participants' samples.
  3. Discovering Biomarkers: We analyze blood, movement, and voice data to identify new biomarkers that can better track ALS disease progression.

In addition to contributing to research, the PMP gives you full access to your personal data, helping you make informed decisions about your own ALS treatment and care.

Only by working in partnership with people with ALS can we create the comprehensive database we need to end ALS.

Why Should You Participate?

By participating in the PMP, you can access your own disease progression data while also helping to find effective treatments for ALS. Unlike other research studies, enrolling in our PMP gives you full access to your personal data, helping you make informed decisions about your own ALS treatment and care. As a PMP participant you will be able to:

  • View your data in a secure, easily accessible online portal.
  • Track your disease progression and follow your symptoms and progression.
  • Access news, updates, and exclusive webinars, through your private, password-protected portal.

As a PMP participant, you can use the program to monitor ANY type of intervention and see the impact that it has on your disease progression, including:

  • Prescribed medications
  • Over-the-counter medications
  • Drug trials
  • Devices
  • Nutritional supplements
  • Exercise programs
  • Dietary change

Most importantly, by sharing your data and your experience with ALS, you will be a part of the world's most focused and experienced effort to end ALS.

Andrea Peet, PMP participant
“I'm grateful to have the opportunity to participate in the PMP. In addition to allowing me to understand and track my disease progression, the PMP makes me feel like I am a true partner in ALS research. It's meaningful for me to know that my data may help ALS TDI to discover potential new treatments for ALS.”

Fernando Vieira, M.D., Chief Executive Officer and Chief Scientific Officer at ALS TDI
“Through the PMP, we partner with people with ALS to learn from their experiences, and couple that information to the data generated by the scientists in our lab. We believe that relating these data can ultimately demystify the processes that drive ALS and reveal pathways for the development of new medicines to treat ALS.”

Initial PMP Outcomes

Our aim is to enroll 750 people with ALS in our PMP. Our PMP includes participants from nearly every US state and over 40 other countries. This pioneering partnership has resulted in the creation of the largest, patient-linked database integrating voice recordings, movement data, medical histories, family histories, genetics, biomarkers, and patient cell biology.

Participants actively provide valuable data every month. As of February, 2023, PMP participants have provided:

  • More than 16,500 voice recordings.
  • More than 21,000 accelerometer activity data sets.
  • More than 18,000 ALSFRS-R scores.
  • More than 33,000 survey responses related to drug, supplement use and other health topics.
Voice Tracking
Once a month, participants are encouraged to record sample phrases to help us interpret changes in speech. To date, we have collected over 13,500 speech recordings from people with ALS.
We collaborate with researchers at Google to leverage their expertise in artificial intelligence to analyze the "big data" collected from our PMP. This research partnership resulted in the development of an algorithm that accurately generates the ALSFRS-R speech score by simply analyzing the series of short recordings of a person's voice. Using this algorithm we have made significant strides towards the development of unbiased, quantitative and sensitive measures of ALS disease progression.
ALS TDI is proud to share that our collaboration with Google has been featured in episode two of "The Age of A.I.", a new YouTube Originals documentary series that takes an immersive look at artificial intelligence and its potential to change the world. Watch the episode on YouTube below.
Wearable Technology
Wearable technology is hugely popular in personal healthcare. In diseases like ALS, where a person is robbed of their ability to move, wearable technology could play a significant role in helping to track disease progression and ultimately be used as an unbiased and sensitive measurement tool in ALS clinical trials.
For the first time, thanks to the hundreds of people enrolled in the PMP, scientists at ALS TDI were able to begin to explore the potential of wearable technology in ALS. They analyzed data from multi-limb accelerometer readings collected monthly from hundreds of people with ALS and compared the data to reported ALSFRS-R scores, the standard outcome measure used in interventional clinical trials.
While additional validation of the model is needed, initial analysis suggests that the use of accelerometers in an ALS clinical trials may reduce the length of a trial and number of participants required by half.
In-Home Blood Collection & Biomarker Discovery
The use of sensitive biomarkers, like glucose levels for diabetes or cholesterol for heart disease, is crucial to the diagnosis, management and tracking of a disease. In the field of ALS research, discovering a sensitive biomarker has been difficult due to the time, costs and logistical burdens associated with these studies.
To help solve some of these issues ALS TDI has launched the first In-Home Blood Collection program in ALS, allowing us to collect multiple blood samples over time from the comfort of our PMP participants' homes. In addition, we are now able to offer whole genome sequencing to participants who are unable to travel to our labs here in Cambridge.
A participant in this program will be sent a blood collection kit and schedule an appointment with a phlebotomist from our partner Phlebotek. After the blood collection, the phlebotomist will ship the samples back to ALS TDI for processing the next day. We aim to collect blood from each participant every three months so that we can evaluate potential biomarkers' properties as disease progresses.
The large number of blood samples we collect over time, paired with all the rest of data we collect in the PMP, gives ALS TDI an exciting and unique opportunity to robustly validate biomarkers for ALS.
Finding The Best Leads To Treat ALS
We are now at a pivotal point in our PMP. Our Translational Research Team has been developing a plan to reprogram human induced pluripotent stem cells, or iPSCs into ALS-related cells in preparation for cell-based drug screening.
Our next goal to screen potential treatments from our compound library in these ALS-related cells. Our compound library, which we acquired in 2019, has 30,000 small molecules, which we hope to screen rapidly in these ALS-related cells. We hope to use the data we gather from these experiments to identify which molecules have a positive impact in the cells, making them good starting points. Promising leads will be moved on to the next stage of drug development, involving more tests in other models of ALS to assess toxicity and, in turn, efficacy.
Screening thousands of small molecules in cells represents a significant shift in our scope. It has the potential to identify better quality leads, earlier on in the process, allowing us to pursue great ideas, faster.
As we continue our working partnership with PMP participants, Google scientists, and other collaborators, we will continue to report on findings from analyses of genetics, blood based biomarkers, clinical disease progression metrics, and cell biology experiments to discover therapeutic targets and streamline clinical development processes for ALS.
