NV-01 study outline and results Dr. Colin Giles Vice President of Clinical and Regulatory Affairs 23 November 2015

Nerve growth factor (NGF): an important pain pathway NGF is involved in nerve growth and pain signaling and highly conserved across species Anti-NGF mAbs have demonstrated significant potency in rodent and human trials (Phase II/III) e.g. PFE/LLY studies of Tanezumab Strong human Phase II clinical data shows efficacy at all doses: a potent pain mediator Tanezumab and knee pain while walking. (Lane et al. NEJM 2010, 363; 1521-31) Towards a mechanism-based approach to pain management in osteoarthritis (2013). Nature Reviews Rheumatology 9, 654–664

NV-01: canine chronic pain A “100% dog” anti-NGF mAb with a superior target product profile to NSAIDs on multiple parameters Nexvet’s NV-01 Chronic pain associated with osteoarthritis Subcutaneous injection once every 4 weeks NV-01 safe and well-tolerated in pivotal and POC studies Pivotal study met primary endpoint Parameter Lead indication Dosing Safety Efficacy 93-97% of 390 vets surveyed would use a product such as NV-01 for the treatment of chronic pain in dogs (country dependent)1 1 Proprietary GfK report

Osteoarthritis and pain in dogs Osteoarthritis (OA) is a painful condition that affects many dogs NV-01 is being developed as a once monthly treatment for the control of pain associated with OA in dogs To gain regulatory approval of a new veterinary medicine, the FDA and other Regulatory Agencies require “substantial evidence of effectiveness” shown by a “pivotal” study in client–owned patients Measuring pain in humans is difficult, so ……… Pain assessment tools for dogs Client-Specific Outcome Measures (CSOM) is tailored to each individual dog as noticed by the owner Canine Brief Pain Inventory (CBPI): pre-defined set of questions to each owner How do you assess pain in dogs? At the office visit by the vet and/or In the home environment by the owner Owner assessments are preferred by the FDA as being the most reliable, the owner and vet must be “masked” to treatment so do not know which medicine (or placebo) is being given

Pivotal study design A study to compare NV-01 administered by subcutaneous injection in comparison to placebo, for the control of pain associated with OA in dogs. Final evaluable case number. Total enrollment was 262. 246 6 study sites in U.S., 3 in France, 3 in Germany Treatment Number of dogs (final evaluable) Treatment days Assessment days Placebo 80 0, 28, 56 0, 14, 28, 56, 84 NV-01 166 0, 28, 56 0, 14, 28, 56, 84 Multi-center, placebo-controlled, randomized, and masked

Treatments and assessments 3 treatments (NV-01 or placebo), are given at days 0, 28 and 56 1 vial per 10 kg of dog body weight, given subcutaneously Assessments are made at days 0,14, 28, 56, and 84 Day 112 final telephone check Efficacy variables: Primary: Clinical success as determined by CSOM (to FDA-concurred criteria, change Day 0-28) Secondary End-points: Clinical success as determined by CSOM (days 14, 56, and 84) and CBPI (days 14, 28, 56, and 84) criteria Veterinary assessments Secondary endpoints are important: as regulatory agencies around the world, including the European Medicines Agency (EMA), will expect to evaluate these additional data Day 0 Day 14 Day 28 Day 112 Day 84 Day 56

Results of study 262 dogs were enrolled in the study, and there were 246 evaluable cases. The primary endpoint was achieved with a statistically significant improvement over placebo in clinical success rate as determined by changes in Client-Specific Outcome Measures (CSOM) score between enrollment and day 28. Clinically meaningful benefits and statistically significant differences over placebo were also achieved for secondary endpoints, namely clinical successes as determined by both the CSOM and CBPI assessment tools at a majority of the time points evaluated. NV-01 was found to be safe and well-tolerated with no significant adverse safety signals observed in the study.

NV-01 pivotal study: overall summary Treatment Days Assessment Day 0 14 28 56 84 112 CSOM success ✔ CSOM group medians ✔ CBPI success ✔ CBPI group medians ✔ CSOM global assessment Significantly different Very close to significance Not significant Final check of dog ✔ P=0.0046 P=0.038 P=0.0268 P=0.0448 P=0.0256 P=0.0025 P=0.0075 P=0.0197 P=0.0237 P=0.0042 P=0.0025 P=0.0003 P=0.0623 P=0.0587 P=0.0549

Other ongoing study Additional study in client-owned dogs is ongoing This study is investigating different dosage regimens and treatment options The study is still in progress; dogs have been recruited from 15 veterinary clinics across the USA Study expected to be complete in Q1 2016 We also plan to evaluate effects of NV-01 on lameness using pressure platforms: assessing force exerted by dog as it moves on the platform as an extra objective measurement for EU regulatory submission Valuable ancillary data to document the effectiveness of NV-01 in the management of OA and improving lameness

What does all this mean? This pivotal study success is a major advance for the NV-01 program It provides a substantial basis for planned submissions for marketing authorization in the U.S., EU, and the rest of the world It also provides strong evidence on multiple efficacy endpoints which is very encouraging for: NV-01’s overall profile the anti-NGF approach to controlling chronic pain in companion animals It also provides strong support for the robustness of our PETization platform in creating effective, safe, 100% species-specific mAbs

The R&D facility: our “Labradory” Origin of the company and PETization platform Strong R&D/biopharma talent Culture based on innovation Supportive R&D tax environment Outstanding Infrastructure: Intending to move to new location within the prestigious Walter & Eliza Hall Institute (WEHI) Our core R&D activities occur in Australia:

PETization: a platform technology for rapid discovery Many of our programs have originated from PETization PETization: Algorithm-based approach that converts mAbs from one species to another Proprietary and patent protected The key advantages of PETization are: Rapid Retention of the affinity of the parent mAb Reduces the risk of immunogenicity Resulting protein sequence is 100% species-specific Cost-effective Scalability across multiple species

Conventional antibody conversion: competitor methods Conventional or ‘traditional’ CDR-grafting and affinity maturation is slow Process is inefficient: affinity of resulting mAb often lower than parent antibody Results in less than 100% species-specific antibody sequence: chance of immune reaction increases

PETization: the Nexvet method Leverages the diversity in expressed IgG variable domain framework sequences (captured in proprietary Nexvet databases) Rapid and robust: an in silico algorithm Complete species conversion with maintenance of parent antibody affinity Results in 100% species-specific antibody sequence

Safety by design PETization process designs 100% species compatibility IgG isotypes used in NV-01 and NV-02 do not recruit complement or activate ADCC Synthetic genes: no dog or cat DNA used in making antibodies Impeccable host CHO-SK1 cell line provenance: as used for human mAbs CHO cell lines negative for all (EU directive) canine and feline pathogens Cells grown in chemically-defined animal component free media Highly purified, multi-stage chromatography including viral inactivation Formulation components are all defined as GRAS No adjuvants needed or used Safety Administration SC or IV
