Cautionary Note Regarding Forward - looking Statements The information in this presentation contains estimates and other forward - looking statements regarding future events, including statements about the clinical and therapeutic potential of our HBV - Cure and Microbiome programs, our ability to receive payments from Allergan Pharmaceuticals International Limited (“Allergan”) under the collaboration agreement, timing of the initiation of and availability of data from our ongoing and planned clinical trials in each of these programs, plans, strategies, milestones, and intentions related to our programs. Certain forward looking statements may be identified by reference to a future period or periods or by use of forward - looking terminology such as “ believe,” “ planned,” “should,” “initiate,” “potential,” “ anticipated,” or “expected.” Such forward - looking statements, which we intend to be covered by the safe harbor provisions contained in Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, are just predictions and are subject to risks and uncertainties that could cause the actual events or results to differ materially. These risks and uncertainties include, among others: the components, timing, cost and results of clinical trials and other development activities involving our product candidates (including those licensed by Allergan); the unpredictability of the nonclinical and clinical development of our product candidates and of the duration and results of regulatory review of those candidates by the FDA and foreign regulatory authorities; our anticipated capital expenditures, our estimates regarding our capital requirements, and our need for future capital; and the possible impairment of, or inability to obtain, intellectual property rights and the costs of obtaining such rights from third parties . These and other potential risks and uncertainties that could cause actual results to differ from the results predicted are more fully detailed under the heading “Risk Factors” in our Annual Report on Form 10 - K for the year ended December 31, 2016 and our Quarterly Report on Form 10 - Q for the quarter ended June 30, 2017 each filed with the Securities and Exchange Commission. It is not possible for Assembly management to predict all risks nor can Assembly assess the impact of all factors on its business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward - looking statements Assembly may make. This presentation also contains estimates and other statistical data made by independent parties and by us relating to market size. These estimates involve a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. In light of these risks, uncertainties and assumptions, the forward - looking events and circumstances discussed in this presentation may not occur and actual results could differ materially and adversely from those anticipated. Except as required by law, we assume no obligation to update publicly any forward - looking statements, whether as a result of new information, future events or otherwise. 2

Hepatitis B: Cure Program Market overview and deficiencies of current treatment Assembly’s HBV Cure Program 8

 

 

Low cure rates with current SOC /Vaccines are Preventative but do not cure those who are chronically infected HBV: Over 300 Million Chronically Infected Patients Globally China Prevalence: ~ 90 million Global Prevalence: >300 million U.S. Prevalence: ~1.5 million EU Prevalence: ~20 million Sources: Jidong Jia. HBV HCV epidem & therapy 2013. 2013 http://www.who.int/hepatitis/en/ 9 ~ 1 Million deaths/year Chronic HBV infection results in chronic inflammation and progressive liver damage, potentially leading to liver cirrohosis , HCC and death Japan Prevalence: ~1.3 million

 

 

Number of HBV patients outnumber HCV + HIV combined with high unmet need for diagnosis and cure 10 Putting the HBV Opportunity into Perspective HCV HBV US Prevalence 3 M 1.2 - 3 M Worldwide Prevalence 160 M 350 M % Diagnosed in US 50% 30% % Diagnosed that are Treated in US 33% 6 - 10% Nature RNA virus DNA virus Challenge Eliminating RNA virus existing in host cytoplasm Eliminating/silencing new and existing cccDNA 2015 US Sales* $ 12.5 B $700 M * GILD master model – Jefferies Research R eport 8.30.17

 

 

11 Current Treatment Paradigm is Inadequate to CURE HBV Mechanism of Action Benefits Limitations Nucleo (t)side Analogs • Inhibit DNA polymerase • Knock out replication virus from RNA to DNA (reverse transcription) • 1x daily dosing • Well tolerated • High resistance barrier • Does NOT completely stop replenishment of cccDNA • Most patients must stay on drug for life • No immuno - stimulatory benefits Peg - IFN • Immuno - stimulatory protein which indirectly combats viral replication • Enhances body’s ability to clear or reduce viral load • Highest cure rates (<10%) of currently available therapies • Does NOT completely stop replenishment of cccDNA • Poorly tolerated • Requires weekly injections • Poor response rate Current treatments inadequately reduce cccDNA ; L ow cure rates Deficiencies of current approved therapies

 

 

Thought we had curative therapy in 2005 Clear evidence that ETV can cure woodchucks based on multiple parameters • ETV exhibited potent activity against Woodchuck HBV • Sustained suppression of viral DNA levels (≥ 8 logs) for 1 - 3 years with weekly treatment – N o rebounds or evidence of resistance • cccDNA levels reduced >4 logs • Average HBsAg levels reduced 91.3% at 24 month time point 12 Unfortunately , this is not what happens in HBV patients with prolonged therapy ‡ Historical control. Tennant, et al. Viral Hepatitis and Liver Disease 1988: 462 - 464 R. Colonno, et al. JID 2001;184:1236 - 45

 

 

We want what we achieved in woodchucks! 13 Aspirational Objectives for Clinical Cure in Humans • Defined length of treatment to remission • Convenient dosing (QD?) and low pill burden • Excellent safety profile, with minimal side effects • Sustained remission off therapy • Viral DNA replication remains undetectable • Reversal of liver damage, lack of hepatic inflammation • Significant reduction in the risk of future HCC development • Elimination and/or silencing of cccDNA • To achieve clinical cure, therapy must target and prevent new cccDNA generation, and if possible, facilitate the elimination or silencing of existing cccDNA

 

 

CpAMs are only modality that stop cccDNA generation HBV Life Cycle: A DNA Virus with Limited Targets cccDNA Generation 14 cccDNA Maintenance

 

 

15 Rationale for CpAM Treatment Resulting in Higher Cure Rates? • Inhibit HBV life cycle at several steps • Inhibit cccDNA generation in Primary Human Hepatocytes • cccDNA exhibit a reasonable half - life ( weeks to months) • ASMB CpAMs : Potent with Excellent Drug - Like Characteristics – In Vitro data indicates potency is enough to effect establishment of cccDNA Absolute and Complete Cure Functional Cure Current SOC • Reactivate the host immune response • Decrease in viral antigens • Clearance of cccDNA • By shutting down the replenishment of cccDNA • Natural loss of cccDNA • Control viral replication • Block reverse transcription Potential Curative R egimen = SOC ( nuc ) + CpAM

 

 

CpAMs CpAMs Inhibit Several Steps of HBV Life Cycle 16 cccDNA Maintenance cccDNA Generation Nucs & Non - Nucleoside RNA Interference CpAMs cccDNA Maintenance Generate empty aberrant capsid formation – Bind to dimer - dimer interface disrupting formation of functional nucleocapsids Prevent encapsidation of pgRNA and Pol – a pre - requisite for RT activity and generation of rcDNA Prevent maturation of infectious viral particles Prevent trafficking of encapsidated rcDNA to nucleus – inhibiting subsequent conversion to cccDNA Alter phosphorylation levels of Core protein – may also lead to Core protein elimination in infected cells CpAMs ? CpAMs work differently than nuc’s : They target Core protein & stop cccDNA generation CpAMs Cp – Core Protein Pol – Polymerase SgRNA – Subgenomic RNA pgRNA – Pregenomic RNA cccDNA – Covalently Closed Circular DNA rcDNA – Relaxed Circular DNA CpAMs ?

 

 

New study shows that the half - life of cccDNA may be shorter than previously believed 17 Measuring the half - life of cccDNA All biological molecules have a half - life, including cccDNA • Longitudinal study conducted on samples (serum and biopsies) from patients with emerging resistance to LVD and TBV • Appearance and enrichment of resistant mutations used as a genetic marker in monitoring populations of viral DNA, pgRNA and cccDNA • Results demonstrated rapid establishment of newly formed cccDNA harboring Nuc - resistant mutations • Significant turnover of wt pgRNA molecules within months suggests that existing cccDNA may decay faster than previously predicted • Little evidence for the maintenance of substantial pools of inactive wt cccDNA in patient samples Data from study to be presented at AASLD, October 2017 in Washington, DC
