Early diagnosis leads to drug treatment that may delay the deterioration of life quality. Competitive advantage over current manual solutions. Strong value proposition for patients, neurologists and payers (deferring costly care). Large target market- many billions in direct and indirect cost. US Patent 5,772,611, approved in 1998. FDA clearance 510(k) - “ evaluation of visuo-motor performance disturbances ”. Working Prototype Extensive data base with hundreds of test results Time to Market – Less then a year.
Matchmaking Israeli Businesses Green Business Development LTD. 3 Background VMT (Visuo-Motor-test) method was developed by Prof. Hocherman, of the faculty of medicine at the Technion. Prof. Hocherman has been involved in basic brain research for over 25 years. VMT was developed within the framework of his research on neurological motor control. The technology and the IP rights are owned by a group of four individuals, Prof. Hocherman included.

More than 2% of the population aged over 65 years are affected. 5%-10% of patients with PD are misdiagnosed (have Parkinson's but are told they have something else),
Matchmaking Israeli Businesses Green Business Development LTD. 5 Cost of PD - direct and indirect The financial cost of Parkinson ’ s Disease to individuals, government and society combined is in the order of $24 billion per year. The study finds that indirect costs - e.g. disability payments by government and insurance plans and lost income due to forced early retirement are $15,000 per patient per year. The direct costs of medicines, surgery, doctor visits, hospitals and nursing homes are $8,800 per patient per year.

Matchmaking Israeli Businesses Green Business Development LTD. 3/0810 Data Analysis - complex parameters The algorithm analyzes and scores the performance in independent tests, comparing Left & Right arms: oTest Time. o(*)Directional Error (DirEr). o(*)Mean percent time of DirEr>50%. oDistance from Path. oVelocity of hand movement. o(*)Number of tracking interruptions. While some of these parameters are standard, the marked (*) measures are unidue to the present system and are protected by patent.
Matchmaking Israeli Businesses Green Business Development LTD. 11 Differential diagnosis of PD The VMT was tested on various groups: oEarly vs. advance PD patients oPD Vs. Essential Tremor patients oPD Vs. Normal subjects
Matchmaking Israeli Businesses Green Business Development LTD. Current methods for diagnosis of PD UPDRS is the standard manual scale based on performance and cognitive tasks. It takes 20-30 min of the neurologist time to complete the test. SPECT Imaging Dopamine uptake ligand beta-CIT, a SPECT agent is the most sensitive of biomarkers for the diagnosis of Parkinson's disease. Beta-CIT targets the dopamine transporter on the dopamine neuronal terminals and quantifies the loss of those terminals.
Matchmaking Israeli Businesses Green Business Development LTD. 13 Clinical Applications Parkinson oScreening for early phase PD patients. oDifferential diagnosis of PD Vs. Essential Tremor and potentially other cognitive & motor dysfunctions. oOptimization of drug treatment for PD patients. Non-Parkinson oEvaluation of attention disorders (ADD/ADHD).

New approaches that offer great promise are currently being tested, based on cell biology and genetic engineering.

Matchmaking Israeli Businesses Green Business Development LTD. 16 Conclusions from Hocherman ’ s Publications based on more then 400 patients VMT test requires high-level motor planning and cognitive capabilities that are not assessed by the standard diagnostic test - the UPDRS. VisuoMotor coordination of hand movements requires complex cognitive skills, controlling movement direction and velocity. A failure of these high-level motor control systems may occur early in the disease and may even precede the occurrence of motor symptoms. The performance in visuo motor coordination test (VMT) is impaired in early PD patients, either pharmacologically treated or untreated. VMT system may differentiate between Essential Tremor patients who may later develop PD and those who wouldn ’ t. Impaired VMT is a pertinent indication for further SPECT imaging in patients with ET, in order to establish a diagnosis of incipient PD. VMT appears to be a promising, inexpensive and friendly adjunct to the diagnosis of PD.
Matchmaking Israeli Businesses Green Business Development LTD. 17 Interviews with 3 experts on PD Prof. M Youdim - Technion Pharmacology: “ Drugs for slowing the deterioration of PD are expected soon (Rasagiline), early detection and treatment are critical ”. Prof. H. Bergman - Neurological Physiology, Hadassah: “ out of all possible indication, early detection is most important ”. Dr. Sharon, Neurologist, Shiba Medical center, Movement Disorders “ for PD patients, no single diagnostic modality can replace all other tests, but for monitoring the effects of medicated PD patients, VMT may serve as a objective quantitative tool ”.
Matchmaking Israeli Businesses Green Business Development LTD. 18 Competitive landscape (preliminary) No commercial products for the diagnosis or screening of PD. Existing methods : oUPDRS - is the standard manual scale based on performance and cognitive tasks. oSPECT & pet CT - both imaging modalities are suggested for evaluating the # of lost neurons. oOlfactory - research level claiming that the lost of smelling capability is indicative to PD.
Matchmaking Israeli Businesses Green Business Development LTD. Advantages VMT is a breakthrough computer based diagnostic procedure encompasses a highly desirable diagnostic tool in the movement disorders clinic. There is not a similar system in the market and the comparison is made vs. the traditional diagnostic methods which are time consuming, less accurate and do not provide quantified results: oSensitive and objective system that minimizes false first and second degree errors. oReliable differential diagnosis between PD and its main alternative condition (essential tremor). oProvides quantitative estimation of the patient's condition. oCost and time savings - Can be operated by a nurse/technician. oDesk top and inexpensive. oEasy to install and use.
Matchmaking Israeli Businesses Green Business Development LTD. ADHD - Attention Disorder How VMT Technology can be used for such an application Shraga Hocherman, Emanuel Tirosh, Sharon Dobrovski Technion, Faculty of Medicine
Matchmaking Israeli Businesses Green Business Development LTD. ADHD Future Development Background 1 Inattention is one of the basic components of ADHD pathology. ADHD diagnosis relies on daily parents\teachers observations of the child’s behavior, and on a clinical interview, but does not include specific testing of attentional functionality. Behavioral impairments that lead to a diagnosis of ADHD derive in many cases from deficits that are not related to attention.
Matchmaking Israeli Businesses Green Business Development LTD. Basic-Test description Basic Test: Move a “mouse” controlled cursor so that it remains within a 1cm target circle that moves along a sinusoidal path from one end of the screen to the other. Loss of the target causes the later to stop in place until re- entered by the cursor. Performance Criteria: Number of target-losing events (Tracking interruptions). Cumulative time of tracking interruptions. Distance from target center. Lateral deviation from the target’s path. Instantaneous directional error. Measurements resolution: 1 millisecond; 0.05 millimeter.
Matchmaking Israeli Businesses Green Business Development LTD. Testing with distraction Performance under distraction: Target distracters & Cursor distracters. The number and combination of distracters determines the attentional demand of the subject. Assessment of the cost imposed by the attentional load by computing the performance difference between the distracted and the basic task. Low distraction level: 1 target distracter + 1 cursor distracter. High distraction level: 3 target distracters + 3 cursor distracters.
