Repurposed existing drugs and updated global health policy and clinical guidelines will be essential for limiting the social and economic devastation caused by this virus. So, we are leading a three-phase multinational Network Medicine clinical study (MNM COVID-19 study). The study will apply Network Medicine methodologies to repurpose existing drugs for SARS-CoV-2 infected patients and update global health policy and clinical guidelines.

Multinational Network Medicine COVID-19 Study
(MNM COVID-19 Study)
2. COVID-19 (the disease) presents a unique challenge.
SARS-CoV-2 (virus causing the disease) is complex, spreads rapidly, and
the varied outcomes of COVID-19 cases challenge what current clinical
research is equipped to handle.
There is a long road ahead to update policy and clinical guidelines, approve
novel treatments, develop effective vaccines, and manufacture enough to
distribute around the world.
3. Repurposed existing drugs in addition to updated global health
policy and clinical guidelines will be essential for limiting the social
and economic devastation caused by this virus.
We need a multifaceted approach to bring this crisis to an end.

12. Biomedical data is distributed over
countless small and large repositories
around the world.
So regulatory and technical barriers
prevent collaborative use of advanced
techniques such as artificial intelligence
to analyze these complex data sets
comprised of clinical data, -omics data,
and other metadata.
To understand the varied disease
manifestations of COVID-19, we need a
way to overcome these barriers.
HOW DO YOU ANALYZE DISTRIBUTED CLINICAL DATA
WITHOUT COMPROMISING PATIENT PRIVACY?
THE CHALLENGE
Our Federated Analysis Data System
(FADS) is built on a decentralized cloud
computing infrastructure that does not
require raw data to be transferred to a
central site for analysis.
THE SOLUTION
13. WHAT IS FADS?
FADS uses federated learning to analyze medical data.
Federated learning is an artificial intelligence (AI)
technique that can analyze data stored at multiple
locations, such as hospitals and outpatient clinics
caring for patients with COVID-19, without the data
ever leaving those locations.
This means FADS enables researchers to analyze
medical data at some of the best hospitals and
outpatient clinics in the US, Europe, and the rest of
the world in order to better understand the varied
clinical outcomes observed in COVID-19 patients.
14. FADS IN A COVID-19 SETTING
Step One: Define Common Data Model
Representative Data in the COVID-19 CDM
Patient Demographics
Age, sex, race, socioeconomic, etc.
Outpatient and Inpatient Medical Record
Past and current medical conditions, interventions,
medications, vaccinations, lab and imaging results, etc.
COVID-19 History
Exposure history, timing, location, and circumstances
Progression of patient symptoms, clinical observations, lab
and imaging results
Medication history, dosage and timing of medications
Therapeutic interventions needed for treatment
Observed results of the medications and therapeutic
interventions
Outpatient outcomes and if transitioned to inpatient setting
Evidence of any long-term complications
The Common Data Model (CDM)
enables researchers to analyze
disparate observational databases.
The concept behind this approach
is to transform data contained
within those databases into a
common format with common
terminologies, vocabularies, and
coding schemes.
15. FADS IN A COVID-19 SETTING
Step Two: Analyze the Data and Deploy Predictive Models
Researchers develop a master set of predictive models based on historical COVID-19
patient data to predict clinical outcomes and identify drugs that can be repurposed to
treat specific patient groups defined by the analysis.
Federated learning techniques enable researchers to deploy copies of the models at
each hospital and outpatient clinic participating in the study while maintaining master
predictive models that don’t require access to underlying patient data.
Master Set of
Predictive Models
Copies of Master
Predictive Models
Deployed Copies of Predictive Models at
Hospitals and Outpatient Clinics
16. FADS IN A COVID-19 SETTING
Step Three: Master Set of Predictive Models Improves Over Time
The master set of predictive models improves each time a deployed model returns an
updated representation of clinical data. This is an iterative process that accelerates as
more hospitals and outpatient clinics join the study.
Deployed Models Learn from Patient Data at
Hospitals and Outpatient Clinics
Deployed Models are Sent Back Periodically to Update
Master Set of Predictive Models
More Deployed Models = Better Predictions from Master Set of Models

18. KEY TAKEAWAYS
COVID-19 AND FUTURE PANDEMICS
The COVID-19 patient registry and Federated
Analysis Data System (FADS) enable
unprecedented analytic capabilities in a
clinical setting and will lead to publications,
public health policies, and updated clinical
guidelines to help COVID-19 patients.
IT’S TIME TO ACT
These new capabilities will have a lasting
effect on the medical community. Federated
learning can untap the full potential of
Network Medicine leaving us better equipped
to address global health issues and better
prepared for the next pandemic.
We would greatly appreciate if you’d consider contributing to help us
launch the MNM COVID-19 Study, establish the patient registry, and
begin onboarding hospitals and outpatient clinics to FADS so we can do
our best to bring an end to this crisis.
