Goal of Intensive Insulin Therapy: Mimic Normal Physiologic Insulin Response (1 of 2) Source: modified from Am Fam Physician. 2004 Aug 1;70(3):489- 500 Role of rapid-acting insulin is to mimic normal insulin release response to meal Long-acting (basal) Optimum rapid-acting (prandial) profile


Goal of Intensive Insulin Therapy: Mimic Normal Physiologic Insulin Response (2 of 2) Source: modified from Am Fam Physician. 2004 Aug 1;70(3):489- 500 Role of rapid-acting insulin is to mimic normal insulin release response to meal Long-acting (basal) Current mealtime insulin alternatives are too slow to accomplish this goal


Failure to Mimic Physiologic Insulin Leads to Unmet Needs and Risk of Adverse Outcomes 1 IMS Data, 2008 GFK Roper Patient Survey, N = 2,000 (projectable) Rapid analogs too slow to prevent high blood glucose after a meal Majority of patients report failure to meet ACE target Many patients feel bad when they are hyperglycemic Hypoglycemia still a problem with current products 72% of T1DM and 54% of T2DM patients on insulin reported hypoglycemia in the past 3 months1 In mild form, significant quality of life impact In severe form, can be fatal Intensive insulin therapy and hypoglycemia associated with weight gain Suboptimal glycemic control Inability to control post meal blood sugar impedes diabetes management <30% of all insulin patients meet ADA A1C goal of <7%1 23

Phase 2 Meal Study in Type 1 Diabetes 4-way crossover standardized test meal study in type 1 diabetes Objective: compare PK and glucose profiles in response to Humulin R +/- PH20 and Humalog +/- PH20 Primary endpoint: PK AUC0-60 Secondary endpoints: Multiple PK parameters, glycemic excursion Study design Stabilize fasting blood sugar (FBS) with glucose/insulin infusion Up to 3 dose finding visits to optimize post-meal (12 oz. Ensure = 60 gm CHO) glycemic response to lispro-PH20 Using "optimized" dose, repeat test meal with lispro alone Data were presented in 2009 25


PH20 Changed Lispro PK Profile and Led to Significant Reduction in Post-Meal Hyperglycemia "Fast In": Exposure in first hour increased 50% vs. lispro (p=.0002)* "Fast Out": Exposure after 2 hours reduced ~45% vs. lispro (p=.027) ACE Goal 26


Phase 2 Type 1 Diabetes Meal Study Conclusions PK results for these preparations confirmed in type 1 patients previous findings from Phase 1 PH20 accelerated insulin absorption compared to insulin alone, combination yielded more physiologic mealtime insulin PK profiles Greater and earlier peak exposure ("fast in") and reduced late exposure ("fast out") compared to insulin alone Faster PK profiles led to significant reductions in postprandial hyperglycemia and were meaningful relative to achieving treatment targets 79% reduction in total hyperglycemic excursion (area > 140 mg/dL) for Lispro-PH20 relative to lispro alone More than twice as many patients met the ACE postprandial glucose goal (2 hr PPG < 140 mg/dL) for Lispro-PH20 (58%) than lispro alone (25%) Lispro-PH20 and Insulin-PH20 were well tolerated 27


Ongoing clinical studies further characterize Ultrafast Insulin Phase 1 euglycemic glucose clamp study comparing 3 marketed fast acting analog insulins +/- PH20 Phase 2 standard meal study in T2DM patients Phase 3 enabling studies Phase 2 3x/day treatment study in T1DM patients compares regular Insulin-PH20 to lispro in a 3 month x 3 month crossover design (initiated 2Q09) Phase 2 3x/day treatment study will compare Analog-PH20 to analog alone (begins 3Q10) Pivotal Phase 3 trials in T1DM and T2DM patients will compare PH20 product candidate to analog insulin Partner or proceed to Phase 3 with most attractive product candidate(s) (Analog-PH20 and/or regular Insulin-PH20) Efficient Development Strategy to Characterize Ultrafast Insulin Value Proposition 28


Less mealtime hyperglycemia More patients meet established goals for postprandial hyperglycemia Accelerated insulin exposure (i.e., fast in) results in early glucose lowering effects and reduced post-meal hyperglycemia Fast in, fast out profile is ideal for insulin pump applications Ultrafast Insulin Could Have Best-in-Class Product Profile vs. Standard of Care Analogs Less hypoglycemia Post-meal hyperglycemic excursions may be controlled with lower doses of insulin with PH20, which would reduce hypoglycemia risk In addition, reduced late post-meal exposure (i.e., fast out) may result in fewer hypoglycemic events Fewer hypoglycemic events and lower insulin doses could result in less weight gain (less self-medicating snacking), especially in type 2 patients Potential for improved outcomes Better mealtime glucose control and reduced hypoglycemia may allow more patients to reach A1C treatment goals 29


HA-rich halos found on many types of aggressive tumors (breast, prostate, pancreatic) HA mediates resistance to chemotherapy and inhibits access of protective immune cells to the tumor cells PEGPH20 depletion of HA collapses HA dependent pericellular halos on tumor cells HA TUMOR CELL + PEGPH20=Halo depleted Halo TUMOR CELL PEGPH20 - HA Depletion Represents A Novel Mechanism for Cancer Treatment PEGPH20 HA 400X 400X Particle exclusion assay


Hyaluronan (HA) Overproduction is Common in Malignancy 87% HA High 46% HA High Approximately 20-30% of all solid tumors overexpress HA to varying degrees All HA overexpressing tumors tested in preclinical models respond to PEGPH20 which has activity alone and enhances activity of other chemotherapeutics 31


IV PEGPH20 in Preclinical Model Results in Rapid Drop in Tumor Interstitial Fluid Pressure (IFP) * IM PC3 tumor pressure in tumor bearing mice measured 20 minutes prior and for 2 hours following IV injection of 10,000 units of PEGPH20 (n=3), or carrier buffer (n=3) ** Heldin et al, Nature Reviews Cancer (2004) + API Buffer + PEGPH20 >80% reduction in tumor IFP within 1st hour 32 High IFP has been shown to reduce the efficacy of cancer therapies due to the inefficient uptake of therapeutic agents**


PEGPH20 Demonstrated Antitumor Activity Alone and When Combined with Docetaxel IV PEGPH20 monotherapy in HA-positive PC3 prostate tumors Combined dosing of PEGPH20 with docetaxel resulted in synergistic anti- tumor activity (survival improvement of 225% for PEGPH20 + docetaxel vs. 59% for docetaxel alone) IV PEGPH20 + Docetaxel combination therapy in HA-positive PC3 prostate tumors Extended dosing duration of PEGPH20 alone revealed significant single agent antitumor activity Kadhim et al., Proceedings AACR; 2009 = Dose 33


PEGPH20 Program Summary Hyaluronan is a major component of the tumor matrix PEGPH20 disrupts tumor matrix via unique mechanism of action and may enhance cancer cell sensitivity to chemotherapeutics Multicenter, open-label, dose evaluation trial of IV administered PEGPH20 in advanced cancer patients underway Additional studies to further assess dosing, safety, and antitumor activity of PEGPH20 alone and in combination with other chemotherapeutics are being planned 34


Milestones for 2010 Presentation of PEGPH20 preclinical data, 2Q10 Presentations of new Ultrafast Insulin data: Phase 1 comparison of three analogs +/-PH20 euglycemic clamp study, 2Q10 Phase 2 standard meal study in T2DM patients, 2Q10 Phase 2 treatment study 3x/day in T1DM patients, regular Insulin-PH20 vs. lispro, 3Q10 Initiation of Analog-PH20 Phase 2 3x/day treatment study, 3Q10 Preliminary data from PEGPH20 Phase 1 clinical trial, 2H10 Completion of Phase 3 GAMMAGARD clinical trial by Baxter in primary immunodeficiency, 4Q10 Potential for additional milestones from the Roche partnership (due to the initiation of clinical trials or other activities) 35
