About The Precision
Medicine Program

The Precision Medicine Program (PMP) is the most comprehensive and longest running translational research study in ALS. Through PMP, researchers at ALS TDI partner with people with ALS around the world to share and gather data on voice, movement, lifestyle, medical and family histories, genetics, biomarkers, and patient cell biology to better understand the disease.

Only by listening to people with ALS and collecting unbiased data will we develop a better understanding of how to slow or stop ALS. With your participation in PMP, we can accomplish our goals of:

  • Discovering new targeted treatments for ALS.
  • Making clinical trials faster and more efficient.
  • Empowering people with ALS by giving them access to their own data.

Only by working in true partnership with people with ALS can we create a comprehensive database and enhance our knowledge of this disease.

“The Precision Medicine Program is unique in multiple ways. ALS is a heterogenous disorder, meaning it can affect each patient differently. The PMP acknowledges that the person with ALS is the expert of their experience with the disease. We partner with them to learn from their experiences and couple that essential information to the data generated by our scientists and technicians in the lab in Cambridge. We believe that relating these data can ultimately demystify the processes that drive ALS and reveal pathways for the efficient development of helpful medicines to treat ALS.”
- Fernando Vieira, MD, ALS TDI Chief Scientific Officer

PMP Progress

How many participants have enrolled in PMP?
How much data has been entered in the PMP?
How many cell lines have been created?
How many genome sequences have been completed?
How many experiments to assess C9orf72 intronic repeat length in DNA from PMP participants have been completed?
121

NOTE: In order to determine the repeat length of C9orf72 in any given individual enrolled in the PMP, scientists have to conduct several experiments. The number above is the total number of experiments done to understand the repeat lengths in the current PMP cohort. This number does not represent the number of individuals in the PMP who have been found to have a pathogenic repeat length associated with the C9orf72 gene.

How many blood samples have been collected and analytes assessed within them?

NOTE: The graph above presents two values. The number of samples collected represents the total number of samples of blood collected, we often collect multiple samples of blood from individual patients. The number of biomarker assessments to date represents the number of analytes explored multiplied by the number of blood samples tested for those analytes. Analytes of interest to ALS TDI include proteins such as SOD1 or CD40L, as well as antibodies against TDP43, among others.

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 July 2019, PMP participants have provided:

  • More than 13,500 voice recordings.
  • More than 15,000 accelerometer activity data sets.
  • More than 10,000 ALSFRS-R scores.
  • More than 21,000 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.
