ASDERA – Approach
Derisking
How: Finding targeted therapies from genetics
through a computational biostatistics platform,
Advantage: the first to identify genetic risk factors for complex diseases
DrugDiscoveryPlatform
(US 7,664,616)
The platform screens not only for individual genetic ‘letter’ positions (SNPs) but genetic ‘words’ (several neighboring SNPs).
It also accounts for genetic ‘grammar’ (neighborhood, compound hetero-zygosity, recombination hotspots, ...) within the statistical method.
Feasible only since 2001 (32-bit OS), it already yielded several hits.

ASDERA – Market Need / Opportunity (Metastatic Cancer)
Breastcancer
Breast cancer (BC) is the most common cancer in women worldwide.
US: ~5,000,000 prevalence (250,000/yr).
Triple-neg.BreastCancer
37,500/yr are triple negative (TNBC, 15% of breast cancer)
• high risk of metastases post surgery (20% at 2.5 yr) [Dent 2007]
• high risk of death (13% at 2.5 yr)
Unmet Need
BC
Most cancer death are caused by metastases
driven by β1 integrin, yet no targeted treatment exists
to prevent metastases to brain, lung, liver, and bone.
Unmet needTNBC withhigh risk
For TNBC, the only treatment options
after surgery have severe side effects:
• radiation
• chemotherapy

ASDERA – Market Need / Opportunity (Neurodegeneration)
Alzheimer’sParkinson’s
Alzheimer’s is the most common form of dementia worldwide (60–80%).
5,500,000 US people are affected with Alzheimer’s (AD).
1,000,000 US people are affected with Parkinson’s (PD).
Unmet Need
AD/PD
There is no effective treatment for AD.
PD Patients often respond initially to L-dopa,
but become refractory
Early stageParkinson’s
Of 60,000 US people diagnosed per year,
4% (2,400) are <50 years old.
• GBA-associated PD causes 31 vs 21% dementia.
• GBA-associated PD progresses faster.
Unmet needEarly PD
with high risk
No specific treatments for GBA-PD are available.
Fast progression shortens trial duration.

ASDERA – Market Need / Opportunity (Atherosclerosis)
CoronaryArtery
Disease
About 92M Americans are living with a cardiovascular disease / had stroke.
More people die of cardivascular diseases, than of all cancers combined.
Risk factors
Risk factors for coronary artery disease (CAD) are
• recent myocardial infarction / stroke
• current smoking / obesity
• uncontrolled blood pressure / LDL / T2DM
Unmet NeedOver the last 50 years, incidence has declined 67%,
but treatments with a direct mode of action are still
ugently needed.
High riskTarget
populations
Risk population / outcome
• recent stroke (14% of 700,000 within one year)
• include MI into outcome to increase power.

ASDERA – Market Need / Opportunity (Multiple Sclerosis)
MultipleSclerosis
About 400K Americans are living with multiple sclerosis.
About 10,000 US cases are diagnosed each year.
Age at diagnosis is 10–80 years, with the marjority being 20–40
Immune system (macrophages) destroyes myelin
Risk factors
Risk factors for multiple sclerosis (MS) are
• genetics, IBD, smoking
• living away from the equator (vitamin D?)
Unmet Need
There is cure available.
• Cortecosteroids, plasmapheresis
• Ocrelizumab (anti-CD20 on B-cells, $65K/yr) reduces
progression, but halted in RA/SLE due to AEs
High riskpopulations
About 15% of patients have primary progressive MS.
PPMS starts ~10 years later.

DiscoveryPlatform
Analyzed three breast cancer (BC) populations ( https://doi.org/10.1101/152405 )
Results suggested a novel treatment concept for a pliotropic risk factor under lying several age-related diseases
Geneticresults
Consistent results showed metastases are associated with
• variations along the endo-/exocytosis (EEC) pathway
• variations in the PI cycle, which regulates EEC.
Considerable overlap with genetic risk factors of AD and PD.
IndependentConfirmation
Of the 27 EEC genes identified, 24 have known function in BC.
“Derailed endocytosis”[Mosesson 2008] is a known component of BC etiology.
“Deranged endocytosis”[vanDooren 2014] is also a known component of AD.
Mode of Action
ASD-003..006 is an innovative (optionally oral) derivatives of αCD;
they down-regulate endocytosis by scavenging serum phospholipids.
βCD was effective in models of BC, AD, PD, CAD, ...

ASDERA – Frequently Asked Questions
1. Why do you get GWAS results where others don’t ?
2. Has the discovery platform been validated ?
35© ASDERA (2017) Non-confidential Information 3535
Genetics ofHeritableDiseases
If a disease are caused by a single genetic ‘letter’ variation (SNP), that variation is ‘selected against’ in just a few generations. Hence, most heritable diseases are ‘epistatic’. Some variations of SNPs (‘words’) cause the disease and are selected against, but the individual letters remain in the populations and recombine (no need for de-novo mutations).
Limitations ofBioinformatics
Tools
Most bioinformatics tools in genetics are based on the statistical methods that were feasible in the 20th century, where memory was scarce. Hence, most GWAS are analyzed one SNP at a time and, thus, can detect only recent (de novo) mutations (‘letters’), but not the common cis-epistatic risk factors (‘words’). Others ignore the sequence of the letters (rwdo = word).
The ASDERADiscoveryPlatform
The ASDERA platform is based u-statistics for multivariate data, which were conceived in the 1940s, but never fully developed, because of memory constraints. Only after 2001 (32-bit OS) became it possible to extend u-statistics to incorporate genetic ‘grammar’ (letter sequence, ...) to increase power and avoid artifacts.
Result Where others fail with 100,000s of subjects, ASDERA succeeds with 100s.

The platform identified all known targets of epilepsy drugs in a sample of 185 cases only. http://www.ncbi.nlm.nih.gov/pubmed/23438886
Epilepsy(PoC)
Mutismin
Autism
The platform identified ineffective hyperpolarization dueto ion-channel defects as causing “regression” and a MFA prodrug to prevent it. http://www.nature.com/articles/tp2013124 (outlicensed)
Crohn’s Disease
(CD)
In CD, the platform identified several fucosylation defects, suggesting supplementing dietary L-fucose as a novel treatment for the many patients who do not respond to anti-AI drugs. https://www.researchgate.net/publication/309375820 )
Breast Cancer
(BC)
As a finalist of the NCI’s U4C breast cancer challenge, the platform identified excessive influx of phospholipids into the PIP cycle as the cause for “derailed endocytosis” and, thus, aCD as a drug to regulate supply of phospholipids for the prevention of metastases.( https://doi.org/10.1101/152405 )
Phase 2/3
subset GWAS
Since the platform can find the “missing heritability” in samples of 100s of subjects only, it can identify genetic risk factors for non-response in phase 3 clinical trials.(confidential)
