EXHIBIT 99.1
Arbutus Reports Fourth Quarter and Year End 2020 Financial Results and Provides Corporate Update
AB-729, Arbutus’ proprietary subcutaneously delivered RNAi agent, demonstrates robust and continuous declines in hepatitis B surface antigen (HBsAg) in subjects with chronic hepatitis B (HBV) with favorable safety and tolerability data
Reductions in HBsAg seen in both HBV DNA negative and HBV DNA positive subjects support a potential dosing schedule for AB-729 as infrequently as every 8 to 12 weeks
Several AB-729 Phase 2 proof-of-concept combination clinical trials expected to initiate this year
AB-836, Arbutus’ proprietary oral capsid inhibitor, on track to begin a Phase 1a/1b clinical trial in healthy volunteers and subjects with HBV in the first half of 2021
Conference Call and Webcast Scheduled Today at 8:45 AM ET
WARMINSTER, Pa., March 04, 2021 (GLOBE NEWSWIRE) -- Arbutus Biopharma Corporation (Nasdaq: ABUS), a clinical-stage biopharmaceutical company primarily focused on developing a cure for people with chronic hepatitis B virus (HBV) infection, as well as therapies to treat coronaviruses (including COVID-19), today reports its fourth quarter and year-end 2020 financial results and provides a corporate update.
William Collier, President and Chief Executive Officer of Arbutus, stated, “Our current data set for AB-729, our lead compound in development for HBV, has grown substantially over the past 12 months and increases our confidence that it has the potential to be a cornerstone drug in future HBV combination regimens.”
Mr. Collier added, “Looking ahead, 2021 is expected to provide us with important insights regarding the potential therapeutic value of several compounds in our proprietary HBV pipeline including: longer term Phase 1a/1b dosing results for AB-729; the initiation of a Phase 2 combination clinical trial with AB-729 and Assembly Biosciences’ lead core inhibitor; initiation of Phase 2 clinical trials for AB-729 and one or more approved or investigational agents; and initial Phase 1a/1b data from our proprietary oral capsid inhibitor, AB-836.”
Dr. Gaston Picchio, Chief Development Officer of Arbutus, commented, “AB-729 has shown impressive reductions in HBsAg with an unremarkable longer term safety profile in the clinical data from our Phase 1a/1b clinical trial. The data that has emerged from this clinical trial so far is encouraging and it suggests that AB-729 could potentially be dosed less frequently than every 4 weeks potentially providing a competitive advantage. As a matter of fact, we are testing a dosing schedule of every 8 weeks in our Phase 2 clinical trial in collaboration with Assembly.”
Dr. Picchio added, “We are pleased that we have initiated screening for our proof-of-concept Phase 2 clinical trial combining AB-729 with Assembly Biosciences’ lead core inhibitor candidate, also known as a capsid inhibitor, vebicorvir, and a nucleos(t)ide reverse transcriptase inhibitor.”
Pipeline Update
AB-729
- Arbutus is currently conducting a single- and multi-dose Phase 1a/1b clinical trial to determine the safety, tolerability, pharmacokinetics, and pharmacodynamics of AB-729 in healthy subjects and in subjects with chronic HBV infection.
- Results to date demonstrate that treatment of AB-729 using the 60 mg and 90 mg doses has been well tolerated after a single dose. Efficacy results to date suggest that repeat dosing using the 60 mg dose every 4 weeks resulted in a continuous and robust mean HBsAg decline at week 24 (-1.84 log10 IU/mL, N=7). Repeat dosing using the 60 mg dose every 8 weeks results in comparable mean HBsAg declines relative to the 60 mg dose every 4 weeks at week 16 (-1.37 log10 IU/mL vs -1.44 log10 IU/mL, p<0.7). In HBV DNA positive CHB subjects, a single 90 mg AB-729 dose resulted in robust mean HBsAg (-1.02 log10 IU/mL) and HBV DNA (-1.53 log10 IU/mL) declines at week 12, as well as decreases in HBV RNA and core-related antigen. Similar mean HBsAg reductions were observed in HBV DNA positive and negative CHB subjects supporting complete target engagement by AB-729.
- Arbutus expects to provide additional data from ongoing cohorts of the Phase 1a/1b clinical trial in the first half of 2021, except for initial data from the 90 mg every 12 week cohort which is expected in the second half of 2021. Based on these results, Arbutus intends to advance AB-729 into two Phase 2 combination trials with one or more approved or investigational agents in the second half of 2021 with dosing of AB-729 as infrequently as every 8 or 12 weeks.
- Arbutus and Assembly initiated screening in a Phase 2 proof-of-concept combination clinical trial to evaluate AB-729 in combination with Assembly Biosciences’ lead core (capsid) inhibitor candidate vebicorvir and a nucleos(t)ide reverse transcriptase inhibitor for the treatment of subjects with chronic HBV infection. The randomized, multi-center, open-label Phase 2 clinical trial will evaluate the safety, pharmacokinetics, and antiviral activity of the triple combination of VBR, AB-729 and an NrtI compared to the double combinations of VBR with an NrtI and AB-729 with an NrtI. Approximately 60 virologically-suppressed subjects with HBeAg negative chronic HBV are expected to be enrolled in the first cohort of the trial. Subjects will be dosed for 48 weeks with VBR 300 mg orally once daily and AB-729 60 mg subcutaneously every 8 weeks, with a 48-week follow-up period.
AB-836: Oral Capsid Inhibitor
- In January 2020, Arbutus selected AB-836 as its next-generation oral capsid inhibitor. AB-836 is from a novel chemical series differentiated from competitor compounds with the potential for increased efficacy and an enhanced resistance profile. Arbutus completed CTA/IND-enabling studies in the fourth quarter of 2020 and anticipates initiating a Phase 1a/1b clinical trial for AB-836 in the first half of 2021.
Early R&D Programs
- Arbutus’ drug discovery efforts are focused on follow-on compounds for its current HBV pipeline and new small molecule antiviral medicines to treat COVID-19 and future coronavirus outbreaks. Arbutus expects to continue to advance its research in its oral PD-L1 inhibitor, RNA-destabilizer and coronavirus programs.
Genevant Sciences Ltd.
Arbutus owns approximately 16% of the common equity of Genevant Sciences Ltd. (“Genevant”), a company Arbutus launched with Roivant Sciences, Ltd. and to which Arbutus licensed exclusive rights to its lipid nanoparticle ("LNP") and ligand conjugate delivery technologies for RNA-based applications outside of HBV. We are entitled to receive tiered low single-digit royalties on future sales of Genevant products covered by the licensed patents. If Genevant sub-licenses the intellectual property licensed by us to Genevant, we are entitled to receive, upon the commercialization of a product developed by such sub-licensee, the lesser of (i) twenty percent of the revenue received by Genevant for such sublicensing and (ii) tiered low single-digit royalties on product sales by the sublicensee.
Financial Results
Cash, Cash Equivalents and Investments
Arbutus had cash, cash equivalents and investments totaling $123.3 million as of December 31, 2020, as compared to $90.8 million as of December 31, 2019. During the twelve months ended December 31, 2020, Arbutus used $51.4 million in operating activities and made a $2.5 million equity investment in Genevant, which was offset by $86.3 million of net proceeds from the issuance of common shares under Arbutus’ ATM program. Thus far during the first quarter of 2021, Arbutus has received an additional $24.3 million of net proceeds from the issuance of common shares under its ATM program. Arbutus expects a net cash burn between $70 to $75 million in 2021 and therefore the Company believes its cash runway extends through the third quarter of 2022.
Net Loss
Net loss attributable to common shares for the twelve months ended December 31, 2020 was $75.9 million ($1.00 basic and diluted loss per common share) as compared to $164.9 million ($2.89 basic and diluted loss per common share) for the twelve months ended December 31, 2019. The decrease in the net loss was due primarily to: i) non-cash impairment charges in 2019 of $43.8 million for an in-process research and development ("IPR&D") intangible asset and $22.5 million for goodwill to reduce their carrying values to zero, as well as a corresponding income tax benefit of $12.7 million related to the decrease in the deferred tax liability associated with the IPR&D intangible assets; ii) a $20.0 million decrease in non-cash equity losses associated with the Company’s investment in Genevant; iii) a $10.1 million decrease in research and development expenses; and iv) a $6.3 million expense in 2019 related to an arbitration award from the Company's arbitration with the University of British Columbia.
Net loss attributable to common shares for the twelve months ended December 31, 2020 and 2019 also included non-cash expense for the accrual of coupon on the Company’s convertible preferred shares of $12.1 million and $11.1 million, respectively.
Operating Expenses
Research and development expenses were $47.5 million for the twelve months ended December 31, 2020 compared to $57.6 million in 2019. The decrease in research and development expenses for the year ended December 31, 2020 versus the same period in 2019 was due primarily to lower clinical expenses in 2020. General and administrative expenses were $14.7 million for the twelve months ended December 31, 2020 compared to $17.7 million for the same period in 2019. This decrease was due primarily to $2.3 million in cash severance and $1.1 million of non-cash stock-based compensation expense related to our former President and Chief Executive Officer’s departure from the Company in June 2019.
Outstanding Shares
The Company had approximately 89.7 million common shares issued and outstanding as of December 31, 2020. In addition, the Company had approximately 10.7 million stock options outstanding and 1.164 million convertible preferred shares outstanding, which (including the annual 8.75% coupon) will be mandatorily convertible into approximately 23 million common shares on October 18, 2021.
COVID-19 Impact
In December 2019 an outbreak of a novel strain of coronavirus (COVID-19) was identified in Wuhan, China. This virus continues to spread globally, has been declared a pandemic by the World Health Organization and has spread to nearly every country in the world. The impact of this pandemic has been, and will likely continue to be, extensive in many aspects of society. The pandemic has resulted in and will likely continue to result in significant disruptions to businesses. A number of countries and other jurisdictions around the world have implemented extreme measures to try and slow the spread of the virus. These measures include the closing of businesses and requiring people to stay in their homes, the latter of which raises uncertainty regarding the ability to travel to hospitals in order to participate in clinical trials. Additional measures that have had, and will likely continue to have, a major impact on clinical development, at least in the near-term, include shortages and delays in the supply chain, and prohibitions in certain countries on enrolling subjects in new clinical trials. While we have been able to progress with our clinical and pre-clinical activities to date, it is not possible to predict if the COVID-19 pandemic will negatively impact our plans and timelines in the future.

About AB-729
AB-729 is an RNA interference (RNAi) therapeutic targeted to hepatocytes using Arbutus’ novel covalently conjugated N-acetylgalactosamine (GalNAc) delivery technology that enables subcutaneous delivery. AB-729 inhibits viral replication and reduces all HBV antigens, including hepatitis B surface antigen in preclinical models. Reducing hepatitis B surface antigen is thought to be a key prerequisite to enable reawakening of a patient’s immune system to respond to the virus. Based upon clinical data generated thus far in an ongoing single- and multi-dose Phase 1a/1b clinical trial, AB-729 has demonstrated positive safety and tolerability data and meaningful reductions in hepatitis B surface antigen.
About AB-836
AB-836 is an oral HBV capsid inhibitor. HBV core protein assembles into a capsid structure, which is required for viral replication. The current standard-of-care therapy for HBV, primarily nucleos(t)ide analogues that work by inhibiting the viral polymerase, significantly reduce virus replication, but not completely. Capsid inhibitors inhibit replication by preventing the assembly of functional viral capsids. They also have been shown to inhibit the uncoating step of the viral life cycle thus reducing the formation of new covalently closed circular DNA (cccDNA), the genetic reservoir which the virus uses to replicate itself.
About HBV
Hepatitis B is a potentially life-threatening liver infection caused by HBV. HBV can cause chronic infection which leads to a higher risk of death from cirrhosis and liver cancer. Chronic HBV infection represents a significant unmet medical need. The World Health Organization estimates that over 250 million people worldwide suffer from chronic HBV infection, while other estimates indicate that approximately 2 million people in the United States suffer from chronic HBV infection. Approximately 900,000 people die every year from complications related to chronic HBV infection despite the availability of effective vaccines and current treatment options.
About Arbutus
Arbutus Biopharma Corporation is a publicly traded (Nasdaq: ABUS) biopharmaceutical company primarily dedicated to discovering, developing and commercializing a cure for people with chronic hepatitis B virus (HBV) infection. The Company is advancing multiple drug product candidates that may be combined into a potentially curative regimen for chronic HBV infection. Arbutus has also initiated a drug discovery and development effort for treating coronaviruses (including COVID-19). For more information, visit www.arbutusbio.com.
