New major risk - Revenue and earnings growth Earnings are forecast to decline by an average of 21% per year for the foreseeable future. This is considered a major risk. Ultimately, shareholders want to see a good return on their investment and that generally comes from sharing in the company's profits. If profits are expected to decline, then in most cases the share price will decline over time as well. In addition, if the company pays dividends it will also likely need to reduce or cut them, striking a dual blow to total shareholder returns. Currently, the following risks have been identified for the company: Major Risks Earnings are forecast to decline by an average of 21% per year for the foreseeable future. Shareholders have been substantially diluted in the past year (108% increase in shares outstanding).

Assembly Biosciences Reports Positive Interim Results from Phase 1B Clinical Studies of Long-Acting Helicase-Primase Inhibitor Candidates Abi-1179 and Abi-5366 Showing Reductions in Viral Shedding Rate and Virologically Confirms Genital Herpes Assembly Biosciences, Inc. announced positive interim results from two Phase 1b studies of its investigational long-acting herpes simplex virus (HSV) enzyme-primase inhibitors in participants seropositive for HSV type 2 (HSV-2) with recurrent genital herpes. These interim results include the first reported Phase 1b data for ABI-1179, evaluating weekly oral dosing. The ABI-5366 monthly oral dosing results are also encouraging and show significant reductions in viral shedding and virologically confirmed genital lesion rate, supporting the continued optimization of exposure to evaluate its potential for monthly oral dosing. In the ABI-1179 study, highly potent antiviral activity was observed with a 98% reduction in HSV-2 shedding rate compared to placebo There have been no serious adverse events reported to date. ABI-1179-101 Study Overview: ABI-1179- 101 is a randomized, blinded, placebo-controlled Phase 1a/b clinical study. Positive interim data have been previously reported for Part A (Phase 1a), evaluating the safety, tolerability and PK of ABI-1179 following single dose administration in healthy participants. Part B also evaluates antiviral activity by measuring changes in viral parameters including shedding rate, quantification of HSV-2 DNA levels obtained from anogenital swab samples, and clinical parameters including genital lesion rate and duration. Due to the observed half-life of ABI-1179, the safety follow-up period for participants extends for 29 days after dosing (Day 57), with safety data available as of the data cutoff date through Day 57 for all participants from these cohorts that completed the evaluation period. The study uses pooled data from placebo recipients across cohorts as a control. As additional placebo recipients are enrolled in later cohorts, the sample size for the pooled placebo will change, which is expected to result in adjustments to both the observed effect sizes compared to placebo and the tests of statistical significance for those observed effects. Additional information about the Phase 1a/b trial is available at clinicaltrials.gov using the identifier NCT06698575. ABI-5366-101 Study Overview: A BI-5366-101 is a randomized, blinded, randomized, placebo-controlled Phase 1 a/b clinical study.

New Risk • Sep 24
New minor risk - Profitability The company is currently unprofitable and not forecast to become profitable over the next 3 years. Trailing 12-month net loss: US$39m Forecast net loss in 3 years: US$15m This is considered a minor risk. Companies that are not profitable are more likely to be burning through cash and less likely to be well established. Ultimately, shareholders want to see a good return on their investment and that generally comes from sharing in the company's profits. Without profits, the company is under pressure to grow significantly while potentially having to reduce costs and possibly needing to take on debt or raise capital to remain afloat. Currently, the following risks have been identified for the company: Major Risk Shareholders have been substantially diluted in the past year (145% increase in shares outstanding). Minor Risk Currently unprofitable and not forecast to become profitable over next 3 years (US$15m net loss in 3 years). Price Target Changed • Aug 18
Price target increased by 8.2% to US$36.25 Up from US$33.50, the current price target is an average from 4 analysts. New target price is 41% above last closing price of US$25.76. Stock is up 73% over the past year. The company is forecast to post a net loss per share of US$3.76 next year compared to a net loss per share of US$6.69 last year. New Risk • Aug 12
New major risk - Shareholder dilution The company's shareholders have been substantially diluted in the past year. Increase in shares outstanding: 145% This is considered a major risk. Shareholder dilution occurs when there is an increase in the number of shares on issue that is not proportionally distributed between all shareholders. Often due to the company raising equity capital or some options being converted into stock. All else being equal, if there are more shares outstanding then each existing share will be entitled to a lower proportion of the company's total earnings, thus reducing earnings per share (EPS). While dilution might not always result in lower EPS (like if the company is using the capital to fund an EPS accretive acquisition) in a lot cases it does, along with lower dividends per share and less voting power at shareholder meetings. This is currently the only risk that has been identified for the company. Aankondiging • Aug 09

Assembly Biosciences Reports Interim Phase 1a Data from Clinical Study of Oral Entry Inhibitor Candidate ABI-6250 for Hepatitis Delta Virus Assembly Biosciences, Inc. announced interim data from several cohorts from the ongoing Phase 1a clinical trial of ABI-6250, the company's orally bioavailable, small molecule hepatitis delta virus (HDV) entry inhibitor candidate. In the cohorts evaluated to date, a mean half-life of four days was observed for ABI-6250 when dosed orally, supporting the target daily oral dosing profile. Additionally, dose-dependent elevations of total serum bile acids (TBA) were seen over both single- and multiple-dose cohorts. Additional studies are planned to explore potential factors associated with these elevations given the role of ABI-6250's target as a bile acid transport. This assessment is expected to include further pharmacological characterization of ABI-6250 and may incorporate additional cohorts in this Phase 1a study. Assembly Bio expects to conduct these activities in parallel with preparations for Phase 2 clinical studies and the completion of ongoing chronic toxicology studies. ABI-6250 is an investigational product candidate that has not been approved anywhere globally, and its safety and efficacy have not been established. ABI-6250-101 is an ongoing randomized, blinded and placebo-controlled Phase 1a clinical study evaluating the safety, tolerability and pharmacokinetics (PK) of ABI-6250 following single- and multiple-ascending oral dose administration in healthy participants. Changes in TBAs are also evaluated as a biomarker for NTCP engagement. Dosing is complete in two single-dose cohorts evaluating doses of 5 mg and 25 mg and three multiple-dose cohorts evaluating doses of 0.05 mg, 0.2 mg and 1 mg, each randomized 6:2 between ABI-6250 and placebo.

Assembly Biosciences Doses First Participant in Phase 1B Portion of Phase 1A/B Clinical Trial of Investigational Long-Acting Herpes Simplex Virus Helicase-Primase Inhibitor Abi-1179 Assembly Biosciences, Inc. announced that the first participant has been dosed in the Phase 1b portion of the Phase 1a/b study of its long-acting herpes complex virus (HSV) helicase-primase inhibitor candidate ABI-1179. The Phase 1b study will evaluate the safety and antiviral activity of weekly oral doses of ABI-1179 over a 29-day treatment period in participants with recurrent genital herpes. Antiviral activity will be evaluated by assessing changes in viral parameters, including HSV type 2 (HSV-2) shedding rate and levels of HSV-2 DNA. Assembly Bio has advanced both ABI-5366 and ABI-1179 into Phase 1b studies after each long-actinghelicase-primase inhibitor candidate exceeded the company's target PK profiles in Phase 1a evaluation in healthy participants. The Phase 1b studies utilize equivalent eligibility criteria and outcome measures and are being conducted at overlapping sites. To maintain enrollment timelines while running both trials concurrently, Assembly Bio has received clearance for an Investigational New Drug application (IND) for ABI-1179 to support expansion of this Phase 1b study to sites in the United States. The studies for both candidates are on track to report interim data in fall 2025. Under the collaboration agreement between Assembly Bio and Gilead Sciences, Inc. (Gilead), Gilead has the right to opt in to an exclusive license for further development and commercialization of ABI-1179 and ABI-5366 after reviewing the Phase 1b data package to be delivered by Assembly Bio following completion of the studies.

Assembly Biosciences Reports Positive Topline Results from Phase 1B Clinical Trial of Next-Generation Investigational Capsid Assembly Modulator ABI-4334 in Chronic Hepatitis B Assembly Biosciences, Inc. announced positive topline efficacy, safety and pharmacokinetic (PK) results from a Phase 1b study evaluating ABI-4334, an investigational next-generation capsid assembly modulator (CAM), in participants with chronic hepatitis B virus (HBV) infection. In the cohort evaluating a 400 mg oral daily dose, potent antiviral activity was observed over the 28-day treatment period similar to that previously reported for the 150 mg dose cohort. The relationship between ABI-4334's observed antiviral activity and its exposure profile was consistent with having reached full engagement of the first mechanism of action for CAMs, inhibition of viral replication, at the lower 150 mg dose. Under the collaboration agreement between Assembly Bio and Gilead Sciences, Inc. (Gilead), Gilead has the right to opt in to an exclusive license for further development and commercialization of ABI-4334 after reviewing the Phase 1b option data package to be delivered by Assembly Bio following completion of this study. ABI-4334 is an investigational product candidate that has not been approved anywhere globally, and its safety and efficacy have not been established. Study Overview: ABI-4334-102 (Study 102) was a randomized, blinded, placebo-controlled, dose-ranging Phase 1b clinical study that evaluated the safety, PK and antiviral activity of ABI-4334. The study was conducted in treatment-naive or off-treatment participants with HBeAg positive or negative chronic HBV infection. Two cohorts of 10 subjects each were randomized 8:2 to receive ABI-4334 at 150 mg (cohort B1), 400 mg (cohort B2) or placebo daily for a 28-day treatment period. Topline Results: In Study 102, ABI-4334 was well-tolerated with a favorable safety profile observed in participants with chronic HBV infection. No pattern of safety signals has been identified and there were no serious adverse events or adverse events that led to study drug discontinuation. Two grade three treatment-emergent lab abnormalities were observed, one alanine aminotransferase (ALT) elevation in a participant receiving 150 mg ABI-4334, and one total bilirubin elevation in a placebo recipient. These risks and uncertainties include: Assembly Bio's ability to maintain financial resources necessary to continue its research activities, clinical studies and other business operations; Assembly Bio's ability to realize the potential benefits of its collaboration with Gilead Sciences, Inc., including all financial aspects of the collaboration and equity investments; Assembly Bio's ability to initiate and complete clinical studies involving its therapeutic product candidates, including studies contemplated by Assembly Bio's collaboration with Gilead, in the currently anticipated timeframes or at all; safety and efficacy data from clinical or nonclinical studies may not warrant further development of Assembly Bio's product candidates; clinical and nonclinical data may not differentiate Assembly Bio's product candidates from other companies' candidates; potential effects of changes in government regulation, including as a result of the change in U.S. administration in 2025; results of nonclinical studies may not be representative of disease behavior in a clinical setting and may not be predictive of the outcomes of clinical studies; and other risks identified from time to time in Assembly Bio's reports filed with the U.S. Securities and Exchange Commission (the SEC).

Additionally, in vitro data presented for ABI-4334 provide further insights into the potential for next-generation capsid assembly modulators to impact markers of chronic HBV infection. The late-breaker Poster presentation titled "Preclinical profiling the ABI-6250, ABI-6250, an first-in-class oral therapy candidate for chronic HDV infection. Results demonstrate that in cell culture, ABI-6250 specifically inhibits both HDV and hepatitis B virus (HBV) at low nanomolar levels and shows selectivity versus a panel of other viruses. ABI-6250 showed minimal effects on cell viability in vitro across multiple cell types, and also selectively inhibited the sodium taurocholate chotransporting polypeptide (NTCP) bile acid transporter compared to a broad range of other transporters in vitro. In vivo, treatment with ABI-6250 elevated total bile acids at doses that did not increase biomarkers for inhibition of other transporters, indicating selective NTCP target engagement. These results support ABI-6250 as an inhibitor of NTCP and describe total bile acids as a biomarker for target engagement that Assembly Bio plans to evaluate in the ongoing Phase 1a study.

Assembly Biosciences, Inc. Presents New Data Highlighting Long-Acting Herpes Simplex Virus Candidate Abi-5366 and Genital Herpes Prevalence and Treatment Patterns At the 2025 Escmid Congress Assembly Biosciences, Inc. announced data from its herpes simplex virus program featured in three poster presentations at the 2025 Congress of the European Society of Clinical Microbiology and Infectious Diseases taking place in Vienna, Austria, on April 11-15, 2025. ABI-5366: a Long-Acting Helicase-Primase Inhibitor candidate for Recurrent Genital Herpes. The ePoster entitled "The safety and pharmacokinetics of ABI-5366, a novel, oral, long-acting HSVhelicase-primase inhibitor: Interim results from a Phase 1a/1b study in healthy participants" showcases clinical data from a single-dose Phase 1a evaluation of safety and pharmacokinetics of ABI-5366 in healthy participants. Results demonstrate that ABI-5366 was well tolerated when administered orally up to 350 mg with no Grade 3 or 4 treatment-related laboratory abnormalities or serious adverse events reported. Further, an observed half-life of approximately 20 days across all dosing cohorts supports the potential for once-weekly or once-monthly oral administration. Preclinical data also reinforce a PK profile supportive of the potential for once-weekly and once-monthly oral dosing and demonstrate distribution of ABI-5366 to tissues relevant to HSV infection. ABI-5366 is being evaluated in the Phase 1b portion of an ongoing Phase 1a/b study in participants with recurrent genital herpes. Assembly Bio expects to report interim Phase 1b data for both ABI-5366 and ABI-1179, a second long-acting helicase-primase inhibitor candidate, in fall 2025. Genital Herpes Prevalence and Treatment patterns: The poster entitled "Estimating Genital Herpes Prevalences and Treatment patterns Among U.S. Healthcare-Engaged Individuals: Insights from Claims Data" features results from a retrospective analysis of data from Forian's hybrid claims ecosystem and electronic health record database, CHRONOS, of more than 40 million individuals to estimate genital herpes prevalence and treatment patterns.

New major risk - Shareholder dilution The company's shareholders have been substantially diluted in the past year. Increase in shares outstanding: 37% This is considered a major risk. Shareholder dilution occurs when there is an increase in the number of shares on issue that is not proportionally distributed between all shareholders. Often due to the company raising equity capital or some options being converted into stock. All else being equal, if there are more shares outstanding then each existing share will be entitled to a lower proportion of the company's total earnings, thus reducing earnings per share (EPS). While dilution might not always result in lower EPS (like if the company is using the capital to fund an EPS accretive acquisition) in a lot cases it does, along with lower dividends per share and less voting power at shareholder meetings. Currently, the following risks have been identified for the company: Major Risks Less than 1 year of cash runway based on free cash flow trend (-US$51m free cash flow). Earnings are forecast to decline by an average of 19% per year for the foreseeable future. Shareholders have been substantially diluted in the past year (37% increase in shares outstanding). Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (US$97m net loss in 3 years). Market cap is less than US$100m (US$82.6m market cap). New Risk • Mar 21

Assembly Biosciences Doses First Participant in Phase 1A Clinical Study of Oral Entry Inhibitor Candidate Abi-6250 for Hepatitis Delta Virus Assembly Biosciences, Inc. announced that the first participant has been dosed in the Phase 1a trial of ABI-6250, the company's orally bioavailable, small molecule hepatitis delta virus (HDV) entry inhibitor candidate. This Phase 1a study will evaluate the safety, tolerability and pharmacokinetics (PK) of ABI-6250 across single and multiple ascending dose cohorts in healthy participants. In addition, the study will look at serum bile acids as a biomarker of ABI-6250's engagement of its target, the transporter used by HDV to infect hepatocytes (sodium taurocholate cotran sporting polypeptide or NTCP). Assembly Bio expects to share data from the Phase 1a study in third quarter 2025. In preclinical studies, ABI-6250 has demonstrated low nanomolar potency across multiple HDV genotypes in vitro, selectivity for NTCP versus other bile acid transporters and a PK profile supportive of once-daily oral dosing. ABI-6250 is an investigational product candidate that has not been approved anywhere globally, and its safety and efficacy have not been established. ABI-6250-101 is a randomized, blinded and placebo-controlled Phase 1a clinical study evaluating the safety, tolerability and PK of ABI-6250 following single and multiple ascending dose administration. Healthy participants will be randomized between ABI-6250 and placebo in up to five single-dose and five multiple-dose cohorts at different doses. Multiple-dose cohorts will evaluate repeat dosing over 10 days. In addition to assessing safety, tolerability and PK, this Phase 1a study will also measure changes in serum bile acid levels, a biomarker of NTCP engagement. The trial results will support dose selection for future clinical studies. Additional information about the Phase 1a trial is available at clinicaltrials.gov using the identifier NCT06740474.

New minor risk - Share price stability The company's share price has been volatile over the past 3 months. It is more volatile than 75% of American stocks, typically moving 11% a week. This is considered a minor risk. Share price volatility indicates the stock is highly sensitive to market conditions or economic conditions rather than being sensitive to its own business performance, which may also be inconsistent. It also increases the risk of potential losses in the short term as the stock tends to have larger drops in price more frequently than other stocks. Currently, the following risks have been identified for the company: Major Risk Earnings are forecast to decline by an average of 24% per year for the foreseeable future. Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (US$97m net loss in 3 years).

New minor risk - Market cap size The company's market capitalization is less than US$100m. Market cap: US$97.5m This is considered a minor risk. Companies with a small market capitalization are most likely businesses that have not yet released a product to market or are simply a very small company without a wide reach. Either way, risk is elevated with these companies because there is a chance the product may not come to fruition or the company's addressable market or demand may not be as large as expected. In addition, if the company's size is the main factor, it is less likely to have many investors and analysts following it and scrutinizing its performance and outlook. Currently, the following risks have been identified for the company: Major Risk Earnings are forecast to decline by an average of 24% per year for the foreseeable future.

Assembly Biosciences Presents New Preclinical Data Highlighting Investigational Helicase-Primase Inhibitors At International Herpesvirus Workshop Assembly Biosciences, Inc. announced new preclinical data from its investigational herpes simplex virus (HSV) portfolio featured in three presentations at the International Herpesvirus Workshop (IHW), taking place July 13-17, 2024, in Portland, Ore. Approximately 50% of individuals with initial symptomatic genital herpes infection have three or more recurrences per year, including over four million people in the United States and France, Germany, Italy and Spain (collectively, the EU4), and the United Kingdom. While genital herpes can be caused by either HSV type 1 (HSV-1) or HSV type 2 (HSV-2), recurrences are more likely to be experienced by individuals infected by HSV-2. The current standard of care for recurrent genital herpes are nucleoside analogs; however, these are only partially effective in preventing recurrences. Assembly Bio’s HSV antiviral candidates target the HSV helicase-primase complex, an essential HSV enzyme complex with no host equivalent, and are designed for long-acting administration. A poster entitled “The Helicase-Primase Inhibitor ABI-5366 Is a Novel, Potent, Long-Acting Inhibitor for the Treatment of Recurrent Genital Herpes” highlights preclinical data that supported ABI-5366’s entry into Phase 1 clinical evaluation. Results demonstrated that ABI-5366 showed low nanomolar activity against both HSV-1 and HSV-2, including broad activity against HSV clinical isolates, and specificity for HSV. ABI-5366 was shown to be generally non-toxic across a variety of cell types with no off-target effects observed in vitro or in vivo, including no activity against carbonic anhydrase esterases. Further, a favorable in vivo safety profile of ABI-5366 was observed in 28-day oral toxicity studies in two species, and pharmacokinetic (PK) studies evaluating ABI-5366 when administered orally or intramuscularly demonstrated long-acting potential for this compound. The Phase 1a/b study for ABI-5366 was initiated in May 2024 and is currently enrolling; interim Phase 1a data are expected in Third Quarter 2024 and interim Phase 1b data are expected in the first half of 2025. Additionally, an oral and poster presentation entitled “Preclinical Characterization of ABI-1179, a Potent Helicase Primase Inhibitor for the Treatment of Recurrent Genital Herpes” features preclinical data from ABI-1179, a structurally distinct, long-acting helicase-primase inhibitor candidate, licensed from Gilead Sciences, Inc. (Gilead) under the collaboration between Assembly Bio and Gilead. ABI-1179 has demonstrated low nanomolar activity across HSV-1 and HSV-2 lab strains and clinical isolates, including acyclovir-resistant isolates. In resistance selection studies, ABI-1179 displayed a higher barrier to resistance development than acyclovir. Furthermore, ABI-1179 demonstrated antiviral activity against some HSV-2 strains harboring mutations known to confer resistance to other helicase-primase inhibitors. In a preclinical study, ABI-1179 demonstrated a favorable PK profile that supports the evaluation of once-weekly oral dosing. Further, in a preclinical model of recurrent HSV infection, ABI-1179 significantly reduced the development of recurrent lesions. Assembly Bio expects to initiate a Phase 1a/b first-in-human study of ABI-1179 by the end of 2024. Aankondiging • Jun 18
Assembly Biosciences, Inc. Doses First Participant in Phase 1B Clinical Trial Evaluating Next-Generation Capsid Assembly Biosciences, Inc. announced that the first participant has been dosed in the Phase 1b trial of ABI-4334, a next-generation capsid assembly modulator (CAM) candidate in development for the treatment of chronic hepatitis B virus (HBV) infection. Chronic HBV (cHBV) infection is a leading cause of chronic liver disease and liver transplants globally, with the World Health Organization estimating that over one million people died in 2022 from HBV-related causes. Current treatments are lifelong and reduce, but do not eliminate, the virus with very low cure rates. CAMs are direct-acting antivirals with two distinct mechanisms of action, inhibition of HBV DNA replication and prevention of the formation of new cccDNA, the viral reservoir. ABI-4334 is a highly potent next-generation CAM with a potential best-in-class profile and has been specifically optimized to target both mechanisms. In a Phase 1a study, once-daily oral dosing with ABI-4334 demonstrated a favorable safety and pharmacokinetic (PK) profile in healthy participants, with ABI-4334 exposure levels projected to achieve strong antiviral activity and double-digit multiples over protein adjusted EC50 for both HBV DNA replication and cccDNA formation. In vitro, ABI-4334 has shown single-digit nanomolar potency against both mechanisms of action and the ability to impact HBV DNA integration. The Phase 1b study that is currently enrolling will evaluate safety, PK and antiviral activity in individuals with cHBV infection over a 28-day treatment period. Aankondiging • Jun 06
Assembly Biosciences Presents New Data Highlighting Hepatitis D Virus Entry Inhibitor Abi-6250 At the Easl Congress 2024 Assembly Biosciences, Inc. announced new data for ABI-6250, the company’s orally bioavailable, small molecule hepatitis D virus (HDV) entry inhibitor candidate, featured in a poster presentation at the European Association for the Study of the Liver (EASL) Congress™, taking place June 5-8, 2024, in Milan, Italy. The poster presentation “Preclinical profiling of ABI-6250, a novel orally bioavailable small-molecule therapeutic candidate for the treatment of chronic hepatitis D” will highlight preclinical data that support the advancement of ABI-6250 into Phase 1 clinical studies. Chronic HDV infection is considered the most serious form of viral hepatitis, and can result in liver cirrhosis, liver cancer, decompensated liver disease or death. ABI-6250 acts to prevent the entry of HDV into cells by blocking access to the sodium taurocholate cotransporting polypeptide (NTCP) bile acid transporter, which is a clinically validated target for HDV infection. Results from preclinical evaluation included in this presentation demonstrate that ABI-6250 can effectively inhibit, at low nanomolar levels, HDV infection of the most prevalent genotypes (HDV-1,-2 and-3) in HepG2-NTCP cells. ABI-6250 also effectively inhibited NTCP-mediated bile acid uptake and demonstrated selectivity for the NTCP bile transporter versus other transporters in vitro. In vivo, ABI-6250 elevated total bile acids, indicating NTCP target engagement without increasing biomarkers for inhibition of other transporters, supporting the selectivity seen in vitro and providing a biomarker for target engagement in Phase 1a studies. The presentation also describes the preclinical pharmacokinetic (PK) profile of ABI-6250, which supports low, once-daily oral dosing in individuals with chronic HDV. Aankondiging • Apr 19

At the meeting, one oral presentation will highlight progress in the company’s HBV/HDV oral entry inhibitor program including activity, selectivity and pharmacokinetic (PK) data that support advancement towards development candidate nomination. A second oral presentation reports new data for ABI-4334 (4334), Assembly Bio’s most potent capsid assembly modulator (CAM) with a potential best-in-class profile, describing the prevention of HBV DNA integration in vitro. The poster presentation, from the company’s interferon-a receptor (IFNAR) agonist program, characterizes small molecule IFNAR agonists that closely mimic interferon-a’s signaling. HBV/HDV Entry Inhibitor Program: HDV is a satellite virus only found in the presence of HBV infection and is considered the most severe form of viral hepatitis. In an oral presentation entitled “Pre-clinical profiling of a novel class of orally bioavailable small molecules potently inhibiting hepatitis B and D virus entry,” the company will present data on a novel class of highly potent, orally bioavailable HBV/HDV entry small molecule inhibitors with favorable drug-like properties. One compound selected for further characterization exhibited potent activity against multiple HBV and HDV genotypes and selective inhibition of sodium taurocholate co-transporting polypeptide (NTCP) compared to other bile acid transporters. This compound further exhibited a favorable PK/pharmacodynamic preclinical profile supporting the potential for once daily dosing. Assembly Bio anticipates nominating a clinical development candidate from the HBV/HDV entry inhibitor program in 2023. Next-Generation HBV CAM Candidate ABI-4334: 4334, which has completed Phase 1a evaluation, is a novel, orally bioavailable investigational next-generation CAM that exhibits nanomolar (nM) potency against pgRNA encapsidation and covalently closed circular (ccc)DNA formation in vitro. In patients with chronic HBV infection, HBV DNA integration has been linked to the development of liver cancer. In the oral presentation entitled “ABI-4334, a novel inhibitor of hepatitis B virus core protein, disrupts DL-DNA containing capsids and prevents HBV DNA integration,” data show that in vitro 4334 disrupts RC (relaxed circular)- and DL (duplex linear)-DNA capsid formation at nM levels and inhibits HBV DNA integration in a dose-proportional manner as shown by inverse PCR and next-generation sequencing analyses?. Based on the Phase 1a PK data, the target plasma levels of 4334 required for inhibition of HBV DNA integration in these models are achievable. Assembly Bio’s IFNAR agonist program seeks to engage IFNa signaling using an orally bioavailable liver-focused small molecule approach to improve tolerability. The poster entitled “Pre-clinical characterization of novel liver-focused small molecules efficiently inhibiting hepatitis B virus by activating type I interferon signaling,” features preclinical data on a novel class of IFNAR agonists that inhibit HBV infection and replication. In vivo analysis of a compound from the series demonstrates that it closely mimics IFNa activity as measured by activating IFN-stimulated response element signaling and inducing the JAK-STAT pathway in the liver and PBMCs. PK data from the same compound exhibit desirable liver exposure and favorable oral bioavailability. Lead optimization of multiple IFNAR agonists is ongoing. New Risk • Aug 18
New major risk - Revenue and earnings growth Earnings are forecast to decline by an average of 0.05% per year for the foreseeable future. This is considered a major risk. Ultimately, shareholders want to see a good return on their investment and that generally comes from sharing in the company's profits. If profits are expected to decline, then in most cases the share price will decline over time as well. In addition, if the company pays dividends it will also likely need to reduce or cut them, striking a dual blow to total shareholder returns. Currently, the following risks have been identified for the company: Major Risks Less than 1 year of cash runway based on free cash flow trend (-US$76m free cash flow). Earnings are forecast to decline by an average of 0.05% per year for the foreseeable future. Revenue is less than US$1m. Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (US$67m net loss in 3 years). Shareholders have been diluted in the past year (8.6% increase in shares outstanding). Significant insider selling over the past 3 months (US$69k sold). Market cap is less than US$100m (US$48.5m market cap). New Risk • Aug 07
New minor risk - Insider selling There has been significant insider selling in the company's shares over the past 3 months. Total value of shares sold: US$69k This is considered a minor risk. There are several reasons why an insider may be selling, including to cover a tax obligation or pay for some other expense. However, we generally consider it a negative if insiders have been selling, especially if they do so below the current price. It implies that they considered a lower price to be reasonable. This is a weak signal, but if there is a pattern of unexplained selling, it can be a sign the insider believes the company's stock is overpriced. Note: We only include open market transactions and private dispositions of directly owned stock by individuals, not by corporations or trusts. Currently, the following risks have been identified for the company: Major Risks Less than 1 year of cash runway based on free cash flow trend (-US$80m free cash flow). Revenue is less than US$1m. Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (US$63m net loss in 3 years). Shareholders have been diluted in the past year (8.1% increase in shares outstanding). Significant insider selling over the past 3 months (US$69k sold). Market cap is less than US$100m (US$57.3m market cap). Aankondiging • Feb 16
Assembly Biosciences, Inc. Nominates First Herpesvirus Development Candidate ABI-5366, a Long Acting HSV-2 Helicase Inhibitor Targeting High-Recurrence Genital Herpes Assembly Biosciences, Inc. announced the selection of development candidate ABI-5366 (5366) to progress to IND-enabling studies for its long-acting herpes simplex virus type 2 (HSV-2) helicase inhibitor program. 5366 is the first development candidate from Assembly Bio’s discovery pipeline nominated for advancement to clinical development since the company announced its expanded research focus outside of hepatitis B last year. Assembly Bio’s HSV-2 program targets the viral helicase-primase, an essential viral enzyme complex and a clinically validated target. Helicase inhibition has demonstrated greater reductions in HSV-2 shedding, lesions and pain compared to approved suppressive nucleoside analog regimens in previous clinical studies. 5366, a small molecule helicase inhibitor with nanomolar potency in vitro, is designed for long-acting administration and has shown favorable pharmacokinetics (PK) for a long-acting therapeutic, including the key property of exceptionally low clearance, in preclinical studies. 5366’s preclinical profile shows the potential for at least monthly dosing, and Assembly Bio will continue to evaluate longer dosing intervals as development and formulation progress. High-recurrence genital herpes associated with HSV-2 infection is characterized by frequent recurrences of lesions (six or more per year) and is estimated to affect up to 40% of HSV-2 genital herpes patients following their first outbreak. Approved suppressive therapy regimens consist of oral daily dosing of nucleoside analogs, a class first approved for genital herpes almost three decades ago, with no new drug approvals in the last 20 years. These suppressive regimens have been shown to reduce the recurrence of genital herpes among patients with high HSV-2 recurrence, but eliminate recurrences for only a minority of these patients.
