7 SUPPRESS for CMV Prevention: Brincidofovir Efficacy Was Confounded by GI Toxicity ▪ Statistically - significant reduction in CMV reactivation in high - risk allo - HCT while on therapy ▪ Higher rate of misdiagnosis of gut GVHD due to drug - related diarrhea in subjects randomized to BCV ▪ Gut biopsies showed BCV - related injury is a histologic mimic of GVHD ▪ 8X higher exposure to steroids in subjects on BCV ▪ Increased use of biologics and other immunosuppressants in subjects on BCV increased risk of late CMV and other opportunistic infections Marty FM, et al. Biol Blood Marrow Transplantation (BBMT), February 2016






Preclinical Data Provide Confidence that IV BCV Will Address Oral BCV’s GI Toxicity 28 - day rat studies of IV BCV: ▪ No animals had diarrhea ▪ All animals gained expected weight during study ▪ No GI findings in intestines at terminal necropsy ▪ No in - life clinical findings at highest dose: IV BCV 15 mg/kg ▪ No transaminase elevations 9 ▪ Significant loss of epithelium in intestinal villi Rat intestine after oral BCV ▪ Minimal single - cell effects noted for IV BCV Rat intestine after IV BCV



IV BCV Delivers Uniform Drug Exposure to Key Organs 0 2000 4000 6000 8000 10000 12000 Liver Kidney Cortex Kidney Medulla Small Intestine AUC all ( µg - equiv*h/g) Total Drug Exposure (AUC all ) in Clearance Organs (rats) IV PO 10 ▪ IV BCV prevents “over - exposure” of gut , with significant improvement in GI tolerability ▪ In rats, IV BCV delivered comparable drug exposure to key organs , including the liver, kidney, and small intestine ▪ Oral BCV resulted in significantly higher exposures in the intestine vs other organs, providing explanation for GI toxicity



11 IV BCV Single Ascending Dose Study in Healthy Subjects: No GI Toxicity ▪ IV BCV 10 mg and 25 mg cohorts are complete ▪ IV BCV 10 mg provides similar exposure as oral BCV 100 mg ▪ Both IV BCV doses were generally safe and well - tolerated: – no drug - related AEs – no gastrointestinal AEs – no graded lab abnormalities • no hematologic toxicity • no kidney toxicity ▪ Single dose of oral BCV 100 mg and 200 mg resulted in ~5% diarrhea, 350 mg 20% diarrhea Oral BCV 100 mg n=51 IV BCV 10 mg n=6 IV BCV 25 mg n=6



12 IV BCV Avoids GI Side Effects, Provides Opportunities for Treatment of All DNA Viruses Oral BCV IV BCV Broad Spectrum ✔ ✔ NO heme toxicity ✔ ✔ NO kidney toxicity ✔ ✔ Prevention of CMV in HCT ✔ Treatment of CMV ✔ Prevention of AdV in HCT ✔ Treatment of AdV ✔ ✔ Treatment of smallpox ✔ ✔ Treatment of BKV/JCV ✔



IV BCV Delivers More Drug to Difficult - to - reach Compartments Including the Brain 0 2 4 6 8 10 12 14 Brain, Cerebellum Brain, Cerebrum and Medulla Spinal Cord AUC all (ug equiv*h/g) Total Drug Exposure (AUC all ) in CNS Tissues (rats) IV PO 13 ▪ Higher CNS exposures with IV BCV could support testing for viral infections in the brain, e.g.: – Herpes encephalitis in newborns and adults – HHV - 6 encephalitis – JC virus/PML in transplant recipients or patients with Multiple Sclerosis



IV BCV Summary, Next Steps for IV and Oral BCV IV BCV ▪ Single Ascending Dose Study in healthy subjects continues, with two additional cohorts scheduled ▪ Multiple - ascending dose study in healthy subjects to initiate in 1H 2017 ▪ Phase 2 dose - ranging studies in CMV and BKV infections to follow ▪ Potential for Phase 3 study design discussions with regulators in 2017 ▪ Opportunity to explore a broad range of additional indications, esp CNS infections 14 Oral BCV ▪ Short - term dosing for treatment of AdV and smallpox continue in development ▪ Small comparative study in pediatric HCT recipients at high risk of AdV disease to begin in 2H 2017, potential for approval based on positive data Our ability to provide BCV in oral and IV formulations enables development across multiple indications and populations with the potential for best - in - class efficacy and safety






16 Oral BCV for Smallpox ▪ Efficacy to be demonstrated via two animal model studies under FDA’s Animal Rule – Pivotal Rabbitpox Efficacy Study demonstrated 100% survival in animals treated immediately with BCV at the time of confirmed infection – Mouse ( ectromelia ) efficacy study results expected in 2017 – Human safety summary of 3 weeks’ exposure to oral brincidofovir submitted to FDA, manuscript submitted to peer - reviewed journal ▪ FDA discussion to follow availability of mouse study data ▪ EU regulatory approvals generally follow FDA approval ▪ Potential for US Procurement to the Strategic National Stockpile, independent of regulatory decisions ▪ Potential procurement opportunities with European countries and non - government organizations currently being pursued Progress Toward Regulatory Approvals & Government Procurements






First Quartile (n=15) Fourth Quartile (n=14) >2 doses cidofovir 11 (73%) 2 (14%) Days from AdV diagnosis (median, IQR in days) 22 (12, 44 ) 6.5 (4, 9) AdV VL (median, IQR in log 10 c/mL) 5.4 (3.1, 6.1) 3.6 (2.3, 5.8) Mortality @ Wk 24 67% (10 of 15) 14% (2 of 14) 18 Adenovirus Rapid Virologic Response on Oral BCV Correlated with Improved Survival ▪ Patients enrolled at initiation of trial had extensive cidofovir use, high AdV viral load , longest period from diagnosis to first BCV dose ▪ In the final quartile of enrollment, patients received brincidofovir more quickly after AdV diagnosis Greatest Impact on Reduced Mortality Demonstrated in Final Quartile of Enrolled Pediatric Patients in Advise Grimley M, et al. ID week, October 2016 14% (2 of 14 )



19 AdVise Case Study: BCV Delivered Robust Antiviral Response, Patient Cleared Infection & Survived 2 year - old cord blood transplant recipient with life - threatening AdV infection AdV Viral Load rises on off - label IV cidofovir After brincidofovir begun: Rapid decline in AdV in blood, urine and stool » Pt alive at Day 250



20 Oral BCV for Treatment of AdV in Pediatric HCT: Study 999 Confidential ▪ Small (n~100), open label, comparative study of BCV vs. standard of care ▪ Inclusion: pediatric HCT recipients with > 1000 c/mL AdV DNA in plasma ▪ Primary endpoint: proportion with undetectable plasma AdV at Week 4 – N=100 (2:1) for 75% vs. 40% response rate – Superiority of BCV in clearance of AdV from plasma could enable conditional EU Approval ▪ Supportive data are being compiled from EU transplant centers – AdVance : incidence and outcomes associated with the standard of care of AdV infections in EU allogeneic HCT recipients – Compilation of EU named patient experience (NPP) with BCV for treatment of AdV after HCT Arm 1: BCV 100 mg* until <LOD (4 - 12 weeks) Randomization (2:1) BCV off treatment follow up to 16 weeks Arm 2: Standard of Care Follow up to 16 weeks Primary Endpoint Assessment at Week 4 * BCV 100 mg BIW or 2 mg/kg for subjects <50 kg

EBMT 2013; total numbers includes all subjects with AdV identified as a primary or secondary DNA viral infection that could not be classified (N=68) e) Ongoing expanded access protocol, n=83 as of 31 Dec 2016



22 BCV: An Opportunity For Treatment of AdV Infection in 6000+ Hospitalizations Annually US AdV - Related Hospitalizations: 2009 - 2013 Actual, Trended From 2014 ▪ In addition to stem cell and organ transplant recipients, other at - risk populations include newborns with severe combined immunodeficiency (SCID), individuals on chemotherapy or biologics for autoimmune diseases, and other immune deficiencies



23 Oral BCV for AdV: Potential First EU Indication In stem cell transplant recipients, AdV viral load is often very high and is strongly associated with fatal outcomes 1,2 Currently no approved therapy; significant limitations with current off - label use of cidofovir and decreasing immunosuppression Early antiviral response in AdVise correlated with improved survival and suggests shorter treatment courses may be effective Improved GI tolerability in pediatric patients 1. Bruno et al. BBMT 2003 2. Lion et al. Blood 2003






Norovirus: Treatment and Prevention of Infections Presents a Significant Opportunity ▪ Noroviruses is the most common cause of epidemic acute gastroenteritis worldwide ▪ $60B each year in healthcare utilization and lost productivity ▪ >60% of norovirus outbreaks in the US are in healthcare facilities ▪ Significant unmet need in immunocompromised population – immunosuppressive therapy is a risk factor for chronic norovirus – 17 - 18% of HCT & SOT recipients experience chronic symptoms of norovirus lasting weeks to years ▪ There are no approved drugs or vaccines for the treatment and/or prevention of norovirus 25



26 Candidate for Norovirus: CMX521 ▪ Norovirus: RNA viruses, previously referred to as Norwalk ▪ CMX521: nucleoside that targets virus RNA polymerase, enabling broad activity against diverse (likely all) wild - type strains ▪ High barrier to resistance in vitro, with >50 passages required to confer any mutations ▪ Proof - of - concept established in mouse model with oral delivery ▪ Toxicology studies in mouse, rat and dog suggest a very favorable safety profile ▪ IND submission and FTIH on track for 2017 E C 5 0 ( µM) C C 5 0 ( µM) SI CMX521 2.1 (n= 33 ) 114 54 Roos - Weil et al, Transplantation 2011
