Circulating tumor cells (CTCs) detach from a solid tumor and enter the blood stream playing a crucial role in cancer metastasis.

Challenges to CTC isolation• Extremely rare: 1-100 CTCs per mL of blood • Other cells: millions of WBCs and billions of RBCs

per mL of blood

Vortex captures circulating tumor cells…

9

The promise has not been realized yet

• CTC enrichment technologies available today are limited by – Complex sample processing– Long processing time– Reliance on cell surface proteins for isolation– Low sample purity– Dilute output volumes that require additional cell

concentration steps. – Poor integration with downstream analytics

10

The right tools support achieving clinical validation

CTCs high in purity supporting sensitive,

accurate analysis

Unaltered by labels or reagents and easily

collected

CTC collection unbiased by molecular

characteristics

Clinical SuccessMinimal manual

intervention and integration with assays

10-50% of CTCs are EPCAM -

Introducing VTX-1

Isolate intact, label free CTCs from whole blood in <1 hour

16

Category Requirement

Cell recovery >60%

Cell recovery variability Standard deviation of <10%

Cell purity performance The average WBCs/mL will be <80 WBCs/mL

Processing time Processing time for 7.5 mLs of blood processed for 1 cycle will be <1.5 hours. For 3 cycles it will be < 3 hours.

Sample volume 7.5 mLs of whole blood with one consumable.

17

Genomic AnalysisGenomic analysis is expected to be the primary method of liquid biopsy characterization and cancer diagnosis.

18

Vortex’s ValueVortex rapidly enriches CTCs with high efficiency and purity, capturing intact CTCs for immediate downstream genomic analysis. - Higher DNA/RNA yields can be extracted from intact cells vs fixed cells

increasing sensitivity - High CTC purity enables sensitive and specific assays- Enrichment in <1 hour ensures RNA expression has not changed

Cell Culture/CDX/Live Cell AssaysCell culture and CDX models allow scientists and clinicians to explore potential treatments before administering them to the patient.

19

Vortex’s ValueVortex enriches intact CTCs with high efficiency, enabling immediate cell culturing or CDX creation. - The fast, gentle process means cells are viable and unharmed. - Cells can be captured directly into a petri dish for culturing - Vortex can easily handle small sample volumes allowing for mouse blood

processing for monitoring CDX and PDX models

Enumeration/IHC/FISHCTC enumeration has been shown to have both prognostic and diagnostic potential. IHC and FISH align well with some existing companion diagnostics and will continue to be a valuable tool.

20

Vortex’s ValueVortex reproducibly enriches CTCs with high purity, capturing CTCs directly on a slide chamber for downstream processing.- The elegant process provides the reproducibility needed for clinical

decisions- The rapid, gentle process results in unchanged protein expression - A 300 µL capture volume makes FISH or IHC protocols simple

Protein AnalysisProtein expression levels can be used as a stratifying assay for many potential treatments. While genomic analysis is favored, actual protein expression will be most appropriate for some drug targets.

21

Vortex’s ValueVortex rapidly enriches CTCs with high efficiency and high purity, capturing CTCs directly into microwells for downstream protein analysis. - The fast, gentle process means protein expression levels are unchanged- The high purity of the CTCs improves the accuracy and sensitivity of

protein assays

Mutations found in the primary and secondary tumors sometimes show up in only CTC or ctDNA

Stopping metastasis (and understanding mechanisms of metastasis) vs killing the tumor is becoming a key area for

future therapeutics

Interest in heterogeneity of disease and how cancer evolves

Interest in RNA expression as an indicator of disease

Interest in CDX and PDX models of disease
