Second Quarter Conference Call and Webcast Scheduled Today at 4:30 PM ET

WARMINSTER, Pa., Aug. 02, 2018 (GLOBE NEWSWIRE) -- Arbutus Biopharma Corporation (Nasdaq: ABUS) today reports its 2018 second quarter financial results and provides corporate update. “With the advancement of AB-506 and AB-452 into clinical development, we are laying the groundwork for a potentially similar paradigm shift in HBV as what has been seen in HCV,” said Dr. Mark J Murray, Arbutus’ President and Chief Executive Officer. “Once the Phase 1a/1b studies are completed, our goal is to rapidly initiate an all-oral combination clinical trial using AB-506 and AB-452 with an approved nucleoside analogue drug. We expect this study to begin by the end of 2019 and move us closer to developing a curative treatment for people with HBV.”

Recent Accomplishments and Upcoming Clinical Milestones

Phase 1a/1b study initiated for AB-506, Arbutus’ second generation, and potentially best-in-class, oral capsid inhibitor. The healthy volunteer portion of the study will be followed by dosing cohorts of HBV patients, with top-line results expected in the second quarter of 2019.

The regulatory filing for AB-452, Arbutus’ novel and proprietary RNA destabilizer, is on track for submission in the third quarter, with subject dosing to follow in the fourth quarter of 2018.

Pending completion of the monotherapy Phase 1a/1b studies for AB-506 and AB-452, Arbutus expects to begin an all-oral combination study with AB-506 and AB-452 with an approved nucleoside analogue by the end of 2019.

HBsAg data from the six-week treatment point of patients in the ARB-1467 Phase 2b combination study (with nucleoside analogue), qualifying patients for PEG-IFN add on therapy will be available in Q4.

Partnership with Alnylam

Patisiran is an RNAI therapeutic targeting transthyretin that is being developed as a treatment for hereditary ATTR (hATTR) amyloidosis. Patisiran is currently under Priority Review as a Breakthrough Therapy with the U.S. Food and Drug Administration. The PDUFA date for patisiran is August 11, 2018.

Successful approval of patisiran will trigger a royalty entitlement to Arbutus for the proprietary LNP technology licensed by Arbutus to Alnylam for patisiran.

Genevant

Genevant, a company formed in the second quarter of 2018 and jointly owned by Arbutus and Roivant Sciences, recently announced that it has entered into a strategic partnership with BioNTech AG, an industry leader in mRNA therapy development. BioNTech and Genevant will develop five mRNA products for rare diseases with high unmet medical need under a 50/50 co-development and co-commercialization collaboration.

Genevant and BioNTech have also agreed to a series of exclusive licenses covering the application of Genevant’s proprietary delivery technology for five oncology targets, for which Genevant is eligible to receive significant commercial milestones. This partnership advances Genevant’s goal of having 5-10 programs in the clinic by 2020 across RNAi, mRNA, and gene editing modalities and positions Genevant as a leader in the development of RNA-based therapeutics. Arbutus is entitled to royalties on any product sales by Genevant. 

Financial Results

Cash, Cash Equivalents and Investments

As at June 30, 2018, Arbutus had cash, cash equivalents and short-term investments totaling $154.9 million, as compared to $139.0 million in cash and cash equivalents, short-term investments, and restricted investments at December 31, 2017.   The increased cash balance was the result of $66.4 million of gross proceeds received in Q1 2018 from the second tranche Preferred Shares issued to Roivant, offset by cash used in operations.

For further details with respect to the Preferred Shares, please refer to Arbutus’ Proxy materials filed on Schedule 14A with the U.S. Securities and Exchange Commission on December 6, 2017.

Net Income (Loss)

For Q2 2018, net income attributable to common shares was $0.6 million ($0.01 basic income per common share) as compared to a net loss of $18.3 million ($0.33 basic loss per common share) for Q2 2017. The Company recorded a non-cash gain of $24.9 million in the second quarter of 2018 related to the formation of Genevant.  See discussion below in Gain on Investment in Genevant.

Revenue

Revenue was $1.2 million in Q2 2018 as compared to $1.0 million in Q2 2017.

In October 2017, Arbutus entered into a license agreement with Gritstone that entitles Gritstone to research, develop, manufacture and commercialize products with the Company’s LNP technology in exchange for an upfront license payment and potential future milestone and royalty payments.   In April 2018, as part of the license agreement for Arbutus’ delivery technologies, Genevant gained the right to receive 50% of future revenues from Gritstone.  Revenue recognized in Q2 2018 relates to Arbutus’ share of the earned portion of the upfront license fee, as well as services provided to Gritstone.

In addition, Arbutus has ongoing license agreements with Alnylam and Spectrum, under which Arbutus is eligible to receive royalties on sales.

Research, Development, Collaborations and Contracts Expenses

Research, development, collaborations and contracts expenses increased to $16.4 million in Q2 2018 from $15.4 million in Q2 2017. Program R&D expenses increased as the Company’s HBV pipeline expands and progresses further into the clinic. In the first half of 2017, Arbutus initiated a Phase 1 clinical trial for AB-423. In the first half of 2018 the Company initiated a Phase 1a/1b clinical trial POS AB-506 (capsid inhibitor) which has shown striking potency and improved PK over AB-423 in preclinical studies. In the first half of 2018 Arbutus has progressed AB-452 (RNA destabilizer) through IND/CTA enabling work to prepare for a regulatory filing in Q3 2018.  Arbutus also continues to incur costs related to its other programs pre-IND/CTA work on AB-729 (GalNAc-RNAi). The increase in program R&D expenses in Q2 2018 was offset by a decrease of $1.2 million related to non-cash compensation expense related to the expiry of repurchase rights.

General and Administrative

General and administrative expenses were $3.8 million in Q2 2018, as compared to $4.6 million in Q2 2017.

General and administrative expenses decreased in Q2 2018 compared to Q2 2017 primarily due to a decrease in non-cash compensation expense related to the expiry of repurchase rights in Q3 2017, offset by professional fees incurred in Q2 2018 related to the launch of Genevant Sciences.

Gain on Investment in Genevant 

As previously announced, on April 11, 2018 Arbutus entered into an agreement with Roivant to form Genevant Sciences, a jointly-owned company focused on the discovery, development, and commercialization of a broad range of RNA-based therapeutics enabled by Arbutus’ proprietary lipid nanoparticle (LNP) and ligand conjugate delivery technologies.  Initially, Arbutus held a 50% ownership interest in Genevant and after additional funding received by Genevant at a stepped-up valuation, at June 30, 2018 Arbutus holds 41% of the outstanding equity of Genevant.   As a result of the equity interest received by Arbutus in exchange for the license of its delivery technologies and other contributed assets, Arbutus has recognized a non-cash gain of $24.9 million during Q2 2018.

Site Consolidation

In February 2018, we announced a site consolidation and organizational restructuring to better align our HBV business in Warminster, PA, by reducing our global workforce and closing our Burnaby facility. In Q1 2018 we began executing our site consolidation plan and substantially completed these activities in Q2 2018. We recorded expenses of $2.6 million in Q2 2018 related to the site consolidation. We expect related total cash expenditures to be approximately $5.0 million and have recognized $4.2 million to June 30, 2018.

Outstanding Shares

The Company had 55.3 million common shares issued and outstanding at June 30, 2018. In addition, the Company had 6.8 million options outstanding and 1.164 million Series A participating convertible preferred shares outstanding, which (including the annual 8.75% coupon) will be mandatorily convertible into 22.6 million common shares on October 18, 2021. Assuming the outstanding options and convertible preferred shares were fully converted, the Company would have had 84.7 million common shares outstanding at June 30, 2018.

Use of Non-GAAP Financial Measures

The Company’s consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States (U.S. GAAP) on a basis consistent for all periods presented. In addition to the results reported in accordance with U.S. GAAP, the Company provides additional measures that are considered “non-GAAP” financial measures under applicable SEC rules. These non-GAAP financial measures should not be viewed in isolation or as a substitute for GAAP net loss and basic and diluted net loss per common share.

The Company evaluates items on an individual basis, and considers both the quantitative and qualitative aspects of the item, including (i) its size and nature, (ii) whether or not it relates to the Company’s ongoing business operations, and (iii) whether or not the Company expects it to occur as part of its normal business on a regular basis. In the three months ended June 30, 2018, the Company’s non-GAAP net loss and non-GAAP net loss attributable to common shares per common share excludes the gain on investment related to the launch of Genevant. The Company believes that the exclusion of this item provides management and investors with supplemental measures of performance that better reflect the underlying economics of the Company’s business. In addition, the Company believes the exclusion of this item is important in comparing current results with prior period results and understanding projected operating performance.
