Slide11What is the risk for developing type 1 diabetes among family members compared to the rest of the population?

Starting Point
Genetic Risk
The path to T1D starts here
Everyone who is diagnosed with T1D has the gene(s) associated with T1DGeneral population risk is 1 in 300Family members are at 15x greater risk to develop T1DRelative risk is 1 in 20

Slide16Why Screen if No Preventative Therapy Currently Exists?
Significantly reduced risk for DKA in TEDDY antibody positive individuals
Up to 36% DKA at diagnosis in
general population
As low as 4-5
% in
with screening and monitoring (unpublished
)
Reduction of DKA can result in better long-term glucose control and lower HbA1c

Slide19T1D Disease Progression

Accelerate the clinical development of therapies by providing a common framework for Regulators, funders, academia and industry Identification of T1D in it’s earliest stages can lead to a decreased risk of diagnosis in DKAStaging diabetes allows us to treat T1D early to delay progression and ultimately prevent stage 3 (symptomatic T1D)Treating high blood pressure, allows us to treat the disease early and ultimately prevent a heart attack or stroke
Importance of staging
Slide20Does someone in your family have T1D?
Risk of T1D in relatives of individuals with T1D Identical Twin: 30-70%Multiple Affected First Degree Relatives: 20-50%Sibling: 8% (but if HLA risk genes identical:30-70%)OffspringFather: 5%Mother: 3%If no Family Hx- General Population: 0.4% (but if HLA risk genes: 4%) (Only 10-15% of newly diagnosed cases of T1D have a relative with T1D)

Slide27Microbiome
Slide28What is the gut microbiome?
28
We have 10x more
bactetrial
cells in our bodies than human cells
We
are walking
ecosystems!
These microbes are integrated into our biology: they
help us digest food, shape our immune system, alter our metabolism and evidence is even starting to show that they affect the nervous system, influencing our mood and
behavior.
Slide29Gut microbiome is altered in T1D
Cell Host & Microbe
17, 260-273 (2015)
Detection of 2+ autoantibodies
Symptom onset
Gut microbiome is associated with immunity
It develops differently in those who progress to symptomatic T1D
There could be a connection between the microbiome and T1D
Slide30Gut Microbiome in T1D Key Messages
30
Our guts are made up of trillions of microbes that play important roles in our biology
Through modern day practices, we may have altered our gut microbiomes in such a way to alter biological processes.
The rate of T1D has been increasing worldwide and may be linked to changes in the microbiome
If we could reset the microbiome at an early age, we may be able to prevent or delay the onset of T1D in some individuals.
Slide31Virus and disease etiology
Slide32Enteroviruses
RATIONALE:Enterovirus detected in new onset T1D pancreas (nPOD-V, DiViD); Islet cell damage in fatal enterovirus infections; Genetic association (IFIH1)Viral infections precede onset of T1D autoimmunity in some casesGAPS & POTENTIAL CHALLENGES:Need to confirm number of causative serotypesIndustry commitment to vaccine developmentGo/no-go data
Slide33Diabetes
60, 276 (2011)
Enterovirus
infection is linked to T1D
Stage 1: detection of 2+ autoantibodies
Enterovirus infections before autoantibodies are detected (
ie
, before stage 1) are more common in people who later develop T1D
There are many factors involved and researchers are working to understand them better
Slide34Funding additional epidemiological studies to strengthen the case for vaccine developmentFunding studies to detect viruses in pancreas in T1D and explore role for chronic viral infection in T1D (nPOD-V)Build the business/regulatory case
Type 1 Diabetes Enterovirus Vaccine: JDRF’s Role
nPOD Viral Group
Slide35The goals of nPOD are to:Maintain a network of procuring and characterizing, in a collaborative manner, pancreata and related tissues (spleen, lymph node, pancreatic lymph node, peripheral blood) from cadaveric organ donors with type 1 diabetes as well as those whom are islet autoantibody positive. Utilizing these tissues, investigators will work together to address key immunological, histological, viral, and metabolic questions related to how type 1 diabetes developsTo find out more information about nPOD, please visit www.jdrfnpod.org
