Genetic Diagnostic Applications

Genetic Diagnostic tests fall under 3 applications:

1. Pharmacogenomic testing

2. Prenatal Newborn testing

3. Predisposition and Diagnostic testing

This report defines the genetic testing market as the sales of test kits, reagent and home brew test revenues. Revenue numbers do not include the instrumentation used to perform the tests and reference laboratory testing revenues

Tests classified for infectious diseases are considered a separate segment of the vitro diagnostic market and are not discussed in this report.



Pharmacogenomic testing

Pharmocogenomic tests are preformed on human DNA to assess the efficacy, safety and therapeutic concentration of a therapeutic treatment. They are performed wto determine the clinical course of therapeutic treatment and clinical drug trials. Revenues do not include drugs or therapies prescribed because of testing results

Market Size - $95 million (US) Forecast (2011) - $468 million (US)

CAGR (2004-2011) - 26%

Barriers Rapidly evolving science hinders establishment of clear regulatory rules

Limiting potential drug’s market size discourages Pharma industry adoption

Key End Users of Genetic testing

Over 1400 molecular pathology labs in the US, with bulk of genetic testing being provided by a few big labs. Creating partnership with any of these large labs secures significant market share

Large Labs: Quest Diagnostics

LabCorp

Genzyme

Medium Labs: Mayo

ARUP ( Associated Regional and University Laboratories Pathologist)

MD Anderson

Regional clinics and hospital Laboratories

Key End User product feature requirements: Clinical Practicality of test

Strong client portfolio and relationship with laboratories

Result turnaround time



Platform Comparisons

Important issue in genetic testing market is deciding which testing platform or technology will have highest adoption rates in Clinical labs

Technology issues are throughput, sample concentration, procedure sensitivity and specificity

Economic issues are costs of instrument and reagents, current platforms available in the lab, and ease of use of the procedures

Genetic testing looks for genetic marker such as Single Nucleotide Polymorphism (SNP) , Restriction Fragment length Polymorphism (RFLP) or short tandem repeat (STR)

Theoretically any marker can be identified through any of the platforms

Real- Time Polymerase Chain Reaction ( RTPC)

Capillary Electrophoresis

Micro-array

Multiplexing Instruments



Platform Comparisons: Capillary Electrophoresis

Electrophoresis Platform:

A method of detection for specific gene sequences using gel electrophoresis

Currently high availability of electrophoresis instrumentation in labs means that kits designed for this platform should have the most rapid uptake.

Least expensive- $15K US for state of the art equipment

Electrophoresis also offers low costs per tests - kit cost $80/patient

Versatile in number of different application

Important platform for low margin test like Cytochrome P450, where US labs do not expect high customer demand, so don’t want to invest in higher costing platforms

Major disadvantage is labor intensity



Platform Comparisons: RT-PCR

RT-PCR Platform:

A method for rapid and simultaneous amplification, detection and quantification of gene fragments or gene expression

Slower adoption than electrophoresis due to the cost of machinery - $30K

Expected to have significant uptake because of prevalence in SNP testing

Currently many specialty labs like Quest Diagnostics have high RT-PCR usage

Cost expected to drop as Roche loses patent protection on many of RT-PCR components, opening the field to competition



Platform Comparisons: Microarrays (Gene Chips)

Microarray Platform: A method for rapid detection of multiple simultaneous gene fragments or

gene expression. Probes that react to patient’s genetic material are arranged in grid pattern on glass or plastic platform. Resulting matches constitute a positive test, which are readily identifiable.

Most Expensive $150K-$180K + $500 per test

Reaction indicate particular genetic sequences, such as those related to diseases, or how people will respond to certain medications. Microarrays also can enable researchers to see which genes are being switched on and off under different medical conditions.

Currently does not have many clinical applications, so drawback for laboratories to invest in platform

Roche’s AmpliChip is only FDA approved microarray test for diagnostic use



Platform Comparisons: Multiplexing

Multiplexing Platform: A method for simultaneous detection of specific gene fragments, gene

expression, immune response proteins and enzymes. Multifunction beads are manipulated to bind and signal the specific presence of a a variety of substrates

More versatile than microarray

Allows more variation with regards to type of test - up to 100 assays to be preformed simultaneously on one sample.

Slower than competing technologies however

Multiplexing technology are expected to gain market share. Example is Luminex’ xAMP technology which is currently is partnership agreements with Abbot Laboratories, EreGen, TM Bioscience.

FDA awarded its first approval for a CF diagnostic test to TM Bioscience’s multi-plexing platform based test.



Regulatory Issues

FDA regulates reagents, kits and instruments sold to and performed by clinical labs.

Diagnostic tests can be sold as Analyte Specific Reagents (ASR) to highly sophisticated CLIA-certified labs. FDA exercised restrain in regulating home- brew tests performed by these labs. No specific clinical, validity or performance claims are allowed for unregulated ASRs. Potential liabilities if a lab chooses to provide an ASR rather than a 510(k)-cleared alternative.

Receiving a 510(k) FDA approval is a significant market barrier: Four FDA approved genetic diagnostic tests:

Roche AmpliChip, used to individualize dosage of antidepressants, antipsychotics, beta-blockers, and some chemotherapy drugs

TM Bioscience (Toronto, Canada) TAG-IT assay for detecting cystic fibrosis

Visual Genetics (Toronto, Canada acquired by Bayer in ‘02) TRUGENE HIV-1 Genotyping Kit, used to detect variations in the genome of the human immunodeficiency virus that make the virus resistant to some anti-retroviral drugs.

Third Wave’s Invader assay detects variations in a gene that produces the enzyme UDP-glucuronosyltransferase, and predicts adverse events. http://www.fda.gov/cdrh/oivd/index.htmlhttp://www.fda.gov/cder/genomics/default.htm
