Cautionary note r egarding forward - looking s tatements 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, a nd intentions related to our programs. Certain forward looking statements may be identified by reference to a future period or periods or b y u se of forward - looking terminology such as “believe”, “planned”, “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 193 3, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, are just predictions and are subject to risks an d uncertainties that could cause the actual events or results to differ materially. These risks and uncertainties include, amon g o thers: the components, timing, cost and results of clinical trials and other development activities involving our product candidates (in clu ding 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 cap ital 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 pot ential risks and uncertainties that could cause actual results to differ from the results predicted are more fully detailed under the head ing “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 com bin ation 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 th is presentation may not occur and actual results could differ materially and adversely from those anticipated. Except as require d b y 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

 

 

Significant need for curative HBV therapies Market Opportunity ~ 240 million patients worldwide, ~90 million in China, ~2 million in US and >600,000 deaths/year globally CURE Eliminate (or Silence) Existing cccDNA Inhibit cccDNA Formation Prevent Virus Replication Limited to nucleos (t)ide analogs ( Nucs ) [ entecavir , tenofovir ] or pegylated - interferon - alpha ( PegIFN - α) Nucs suppress and maintain viral load at undetectable levels for years, BUT: – Less than 10% of patients achieve a sustained response off therapy 1 – NOT curative because they have limited effect on cccDNA • IFN’s are poorly tolerated, compliance is challenging, and cure rates are low Current therapies are inadequate ASMB believes a cure is possible • Decreasing/silencing cccDNA levels likely required to increase cure rates • Some patients have been cured • Woodchuck model shows cure correlated with elimination of detectable cccDNA 2 7 1 Marcellin, P . et al.
