T1D Disease Progression

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

Progression by Population:

s will continue to progress towards clinical symptomsT1D starts when you develop two or more autoantibodies

Slide16

Why 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with screening and monitoring (unpublished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

T1D Disease Progression

19

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

Slide20

Does 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)

Eligibility Requirements

Anyone between age 1 and 45 with a sibling, child or parent with type 1

Anyone between age 1 and 20 with a sibling, child, parent, cousin, uncle, aunt, niece, nephew, grandparent or half-sibling with T1D

Those under 18 who do not

have autoantibodies can be retested every year

Microbiome

Slide28

What 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.

Slide29

Gut 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

Slide30

Gut 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.

Slide31

Virus and disease etiology

Slide32

Enteroviruses

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

Slide33

Diabetes

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

Slide34

Funding 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

Slide35

The 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
