Preclinical Phase 1 Phase 2 Phase 3 Marketed Pharmaceutical Pipeline Compounds Formulated with D-Tagatose SPX 8522876 dyslipidemias Dose Ranging Study (D-Tagatose) Type-2 diabetes Phase 2 Ongoing SPX 7233801 atherosclerosis SPX 10624258 metabolic syndrome SPX 8818309 obesity SPX 8818440 diabetes NEET Study (D-Tagatose) 1 Type-2 diabetes Phase 3 Ongoing 1. Proceeded directly from phase 1 to 3 due to FDA GRAS approval

What is D-Tagatose? Structurally, a naturally occurring L-epimer of D-fructose with an inversion at C4 Spherix Incorporated used chiral carbohydrate research to create L-sugars that would not be metabolized, but would retain sweetness D-Tagatose D-Fructose

Overview of D-Tagatose Being evaluated in phase 2 and phase 3 clinical trials as a first-in-class natural oral diabetes treatment Originally developed as a reduced calorie sugar substitute 92% as sweet as sucrose with only 38% of the calories (1.5 kcal/g, compared to 4 kcal/g ) D-tagatose is safe for use in food US FDA (GRAS) since 2001 WHO JECFA since June 2004 EU since 2006 Approved for use as a low calorie sweetener in foods, and in the U.S. as an excipient in non-chronic OTC drugs (throat lozenges, cough syrup), toothpaste, mouthwash and cosmetics

How D-Tagatose is Made Produced from lactose in a 2-step process lactose galactose glucose D-Tagatose isomerized enzymatically hydrolyzed Product specification: >98.0% D-tagatose (dry weight basis)

What Makes D-Tagatose Different? Approved for use in food; established safety profile Chemically, it is an epimer of fructose with an inversion at C4 Behaves like and contains the identical constituent elements as L-tagatose but the human body lacks the enzymes to efficiently metabolize its structure D-Tagatose is poorly absorbed in the small intestine (25%), prevents the stimulation of insulin secretion (no beta cell exhaustion) and naturally lowers blood glucose levels Absorbed D-tagatose is metabolized to CO2 and H20, at a slower rate compared to related sugars (e.g., fructose and glucose) Passes to lower intestine, where it is fermented by bacteria to produce short-chain fatty acids and carbon dioxide

Established Safety Profile of D-Tagatose Preclinical studies (rodents) Acute: LD50 > 10 g/kg Subchronic : 28 day, 90 day, 13-Week: NOAEL at 5% in diet 2 Years: NOAEL at 5% in diet No maternal toxicity, embryotoxicity, or teratogenicity up to 20 g/kg/day (gavage) Not genotoxic Clinical studies Over 20 studies in healthy, diabetic, hyperuricemic or gouty individuals, at doses up to 25 g per eating occasion and 75 g per day reported gastrointestinal symptoms that were mild and transient; no adverse effects on clinical chemistries, hematological parameters or urinary endpoints. Types and severity of gastrointestinal symptoms similar to other incompletely absorbed carbohydrates or polyols.

Mechanism of Action D-tagatose D-tagatose-1-P DHAP + GA CO2 + H2O Glucose Glucose-6-P Glucose Glycogen Aldolase B Glucokinase Metabolism of tagatose in liver is identical to that of fructose. But the cleavage of tagatose-1-P occurs at only about half the rate of that of fructose-1-P Glycogen Synthase Glucose-6-P produced by glucokinase promotes the activation of hepatic glycogen synthase Glucose-1-P Glycogen Phosphorylase Similar to fructose-1-P, tagatose-1-P is an inhibitor of glycogen phosphorylase pathway action

Mechanism of Action In other words.... D-Tagatose depresses elevations of blood sugar levels by increasing glycogen synthesis while decreasing glycogen utilization, resulting in effective control of blood sugar and modulation of HbA1c Blood sugar Glycogen synthesis Glycogen utilization = Controlled Blood Sugar & HbA1c

No Stimulation of Insulin Secretion Most patients with type 2 diabetes experience gradual loss of glycemic control, even with effective oral drugs Progressive failure of beta-cells ultimately responsible Toxicity because of elevated glucose and/or lipid levels, Increased secretory demand because of insulin resistance, Amyloid deposition and altered levels of cytokines D-Tagatose lowers blood glucose and lipid levels D-Tagatose does not stimulate insulin secretion

Pharmaceutical: Phase 3 Trial D-Tagatose NEET Study (Protocol 70971-004) Double-blind phase 3 clinical trial 443 patients randomized 30 Sites in the USA, 32 Sites in India Powered to detect 0.5% HbA1c reduction Endpoints Primary: HbA1c Secondary: glucose, insulin, and lipid profiles, changes in body weight Expect interim data in Q4 2009 Anticipate NDA filing in 2H 2010

Pharmaceutical: Phase 3 Trial D-Tagatose (Protocol 7091-004) Interim blinded data analysis Statistical significance for the pre-specified change of 0.5% in HbA1c (the primary endpoint) can be achieved with the current sample size Favorable change in variability of HbA1c from baseline Results of the secondary variables, LDL, HDL, triglycerides, and body mass index (BMI), are in agreement with the HbA1c results The results demonstrate a significant decrease in the mean BMI at all time points evaluated compared to baseline A consistent decrease of BMI and serum triglycerides was observed at each patient visit A statistically significant reduction in HDL and LDL was seen compared to baseline

Interim blinded data analysis - additional information NIH Medline Plus states that, in general, an HbA1c of 6% or less is normal, and diabetic patients should try to keep their HbA1c level at or below 7% The blinded interim analysis also looked at a summary of HbA1c "responders" (i.e., subjects achieving HbA1c target of <6.5%) At the time of the interim analysis, not all subjects had finished the entire treatment course of this trial; therefore the number of responders was different for different months of therapy The incidences of responders achieving an HbA1c target of less than 6.5% at 1, 2, 4 and 6 months of treatment were 4%, 13%, 19% and 18% respectively Pharmaceutical: Phase 3 Trial D-Tagatose (Protocol 7091-004)

Pharmaceutical: Phase 2 Trial D-Tagatose (Protocol 70971-005) To evaluate the dose-response effect of minimal doses of D-tagatose on glycemic control in subjects with type 2 diabetes under diet control and exercise Phase 2 Six-month Multi-center Single-blinded Randomized Parallel clinical study

7.5 g group reduction of 0.3% in HbA1c from the HbA1c of the 2.5 g group. 5.0 g group averaged a reduction in HbA1c of 0.05% from the 2.5 g group. Triglycerides: 59 mg/dl LDL: 13 mg/dl, HDL: 0.9 mg/dl. The LDL:HDL ratio: improved by 0.3 Triglycerides LDL HDL LDL:HDL Preliminary data after 6 months on drug HbA1c Pharmaceutical: Phase 2 Trial D-Tagatose (Protocol 70971-005)

Pharmaceutical Market Opportunity Source: The American Diabetes Association, 2009 23.6 million children and adults 7.8 % of the population 24% (5.7 million) are undiagnosed US Prevalence of Diabetes

Pharmaceutical Market Opportunity Type 2 Diabetes Results from insulin resistance, a condition in which cells fail to use insulin properly, sometimes combined with relative insulin deficiency Most Americans who are diagnosed with diabetes have type 2 diabetes Many people destined to develop type 2 diabetes spend many years in a state of Pre-diabetes "America's largest healthcare epidemic” Occurs when a person's blood glucose levels are higher than normal but not high enough for a diagnosis of type 2 diabetes As of 2009 there are 57 million Americans who have pre-diabetes
