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 – in vitro / Animal Evidence for Efficacy of CDs in BC

In vitro

βCD reduces migration of human BC cells [Raghu 2010, Donastello 2012, Guerra 2016]

αCD is >2× as effective as βCD in two BC cell lines (p=.0252)

=> βCD acts by scavenging PLs (like αCD) not by scavenging cholesterol

ex vivoβCD inhibits angiogenesis in chick embryo and rat aorta assays,

without altering cell proliferation [Watson 2013]

in vivo

βCD, in mice implanted with human tumor cells,

• reduces tumor volume from MCF-7 BC and A2780 OC cells [Grosse 1998]

• reduces lung metastases from H7-O Lewis lung cancer cells [Zhang 2006]

• reduces invasion of melanoma cells [Fedida-Metula 2008]

ClinicalLPA� has been linked to BC risk.[Wang 2016]

Trials of alkyl-LPCs against BC metastasis showed GI toxicity.[Rios-Marco 2017]

ASDERA – Frequently Asked Questions

1. Why do you get GWAS results where others don’t ?

2. Has the discovery platform been validated ?

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.

ASDERA – FAQ: Why do you get GWAS results where others don’t ?

36© ASDERA (2017) Non-confidential Information 3636

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)
