1 SciDose LLC An Overview
Joseph Bohan, CEO and Co-Founder Amherst Entrepreneurship/Innovation Day March 4th, 2011 NON-CONFIDENTIAL

2 SciDose LLC Background
Nagesh Palepu and Joseph Bohan are co-founders and controlling shareholders of SciDose. Martin Zeiger and Hoyoung Huh are advisors and minority shareholders Company is self-funded to date by signing co-development deals with partners who pay milestones in return for profit split of products The R&D facility, TherDose, an Indian Pvt EOU, SciDose subsidiary established in Hyderabad, India in December Campus will expand to oncology injectibles production in 2011 All Intellectual Property, resulting from formulation work done in India, is owned and patents have been filed by SciDose for worldwide application NON-CONFIDENTIAL 2

3 Business Cornerstones for SciDose

7 Why Focus on Oncology & Hospital-Based Products
Improved cytotoxic drugs with fewer side effects and better efficacy will have rapid acceptance by doctors and patients (fast sales ramp) Worldwide sales opportunities (US/EU, China and India/Brazil) Small sales forces required for promotion of these products Well defined end-points for clinical trials Fast development timelines and limited patient trials using 505(b)(2) strategy (high probability of success using established agents) Cytotoxic drugs will remain as core therapies with broader indications & reimbursement than novel biotherapies NON-CONFIDENTIAL 7

8 Improving Taxotere® (docetaxel): The SciDose® Advantage
Marketed by Aventis with sales over $2.9 in 2010 Taxotere is dissolved in Tween-80 and diluted in IV infusion bags prior to administration to patients Patients are heavily pre-medicated with steroids and antihistamines to prevent anaphylactic reaction The recommended dosing is 6 cycles Taxotere Composition of Matter / Use Patent expired November 2010, and two formulation patents invalidated Signed development deal with Handok for 505(b)2 Paragraph IV filing with limited clinical studies or sNDA with Sanofi Aventis NON-CONFIDENTIAL

9 SciDose Proprietary Docetaxel (SD009) Commercial Opportunity
SciDose has developed a novel, IP-protected, soluble, bioequivalent formulation of docetaxel. Product Profile: new formulation, improved safety, same presentation Novel formulation does not contain Tween-80 or ethanol No steroid premedication (single I.V. dose of H1 & H2 anti-histamines) Bioequivalent to Taxotere (all 5 indication given by FDA) Single-vial presentation equivalent to new Taxotere® presentation Improved 8 hour stability upon first dilution Multi-dose vial system (160mg MDV) for hospital pharmacy cost efficiencies and flexibility for different dosing regimens (q 3 weeks, weekly) Novel J-code opportunity for 1 mg unit reimbursement Opportunity for weekly dosing in future NON-CONFIDENTIAL

13 SciDose-UMass Alliance An Overview
Todd Emrick & Hitha Palepu Amherst Entrepreneurship/Innovation Day March 4th, 2011 NON-CONFIDENTIAL

14 Agenda Novel polymer technology overview
History of the UMass-SciDose alliance UMass-SciDose product development UMass-SciDose portfolio NON-CONFIDENTIAL

15 Synthetic Polymers as Nanotherapeutics
Exploit beneficial aspects of polymers: Derived from non-biological sources, tailored properties, conjugation, architecture, multivalency, degradable, and non-degradable options Nanomedicine for complexation and delivery Normal vessels have tight junctions. Minimize extravasation into healthy tissue Tumor vessels are disorganized and leaky Capillary width [~ 5 µm] pH ~ 7.4 pH ~ Polymer-drug conjugates are large and tend to be taken up preferentially into tumor tissue (passive, selective uptake) Enhanced permeation and retention effect NON-CONFIDENTIAL

16 Advantages of polyMPC Technology
Objective: Use polymers to improve the safety and efficacy of oncology drugs Increase the size of drug: Exploits enhanced permeation and retention effect Lengthens in-vivo circulation time (improved PK profile) Can improve drug stability in vivo Improve the aqueous solubility of hydrophobic drugs (i.e. CPT) Enable high drug-loading onto a water soluble polymer scaffold Linear polymers (i.e., PEG) have drug substitution at chain-end(s). This limits drug loading on the delivery system. Grafted polymers can have high drug loadings, as long as water solubility can be maintained. Drug Polymer backbone Drug-to-backbone linker NON-CONFIDENTIAL

17 polyMPC-CPT Conjugates
Objective: prepare a CPT delivery system with excellent water solubility and controllable release. MPC ATRP initiator Camptothecin TMS-PgMA CuBr/bpy DMSO/MeOH One-pot ATRP polymerization/click reaction > 15 wt% loading of CPT Mol.Wt. 32 kDa methanol (flow marker) PolyMPC-CPT Multiple copies of drug on backbone NON-CONFIDENTIAL

18 polyMPC-Camptothecin Conjugates
Drug loading up to 18 wt%; compare to 1.7 wt% in Prothecan, 3.7 wt% in EZN-2208 CPT equivalent solubility 36.7 mg/mL, compare to 6.7 mg/mL SN-38 in EZN-2208 Mn 7,900 g/mol PDI 1.27 Linkers Z 6.8 nm NON-CONFIDENTIAL

19 CPT Release Profiles in Different Media
P10 Z = P11 Z = Medium PBS 7.4 Mouse serum Cell Culture Medium Human Plasma T1/2 P10 212 h 80 h 43 h 8.4 h P11 220 h 76 h 37 h 9.0 h T1/2 determined by HPLC, monitoring drug release NON-CONFIDENTIAL

20 Cell Culture Analysis of polyMPC-CPT Toxicity
MCF7 cells OVCAR-3 cells COLO 205 cells polyMPC-graft-CPT P11 polyMPC-graft-CPT P10 IC50 values (µM) Cell type P10 P11 CPT MCF7 6.7 4.6 0.29 OVCAR-3 3.3 2.5 0.13 COLO 205 3.9 2.3 0.32 The higher IC50 values for CPT-polyMPC conjugates are due to the expected gradual release of the drug from the polymer backbone Comparable IC50 values for conjugates P10 and P11 originate from their similar hydrolysis rates. The very high drug solubility and slow drug release stand to potentially benefit future in vivo therapeutics. Cell viability: CellTiter Glo luminescence assay NON-CONFIDENTIAL
