Under the terms of the amended and restated agreement, Helsinn will gain an exclusive license to commercialize infigratinib in the U.S. and will be responsible for developing, manufacturing and commercializing infigratinib in oncology indications worldwide except for achondroplasia or any other skeletal dysplasias and except in mainland China, Hong Kong and Macau. BridgeBio will be eligible to receive regulatory and commercial milestone payments as well as tiered royalties on adjusted net sales from Helsinn. BridgeBio will retain all rights to develop, manufacture and commercialize infigratinib in skeletal dysplasia, including achondroplasia.

In 2021, Helsinn and BridgeBio obtained accelerated approval for TRUSELTIQ (infigratinib) from the U.S. Food and Drug Administration (FDA) for the treatment of adults with previously treated, unresectable locally advanced or metastatic cholangiocarcinoma with a fibroblast growth factor receptor 2 (FGFR2) fusion or other rearrangement as detected by an FDA-approved test. Additionally, the two parties received conditional approval by Health Canada and provisional approval by the Therapeutics Goods Association in Australia for TRUSELTIQ (infigratinib) for the treatment of adults with previously treated, unresectable locally advanced or metastatic cholangiocarcinoma with a FGFR2 fusion or other rearrangement. Continued approval in the U.S., Canada and Australia for this indication may be contingent upon confirmatory trials.

Infigratinib is not FDA-, Health Canada- or Therapeutics Goods Association-approved for any other indication in the United States, Canada and Australia, and is not approved for use by any other health authority.

Giorgio Calderari, Helsinn Group CEO commented, "We are delighted to gain the exclusive license to commercialize infigratinib in the U.S. This perfectly complements our recently announced Fully Integrated Targeted Therapy (FITT) Strategy and will utilize our unique capabilities and expertise to take products through development and to patients living with cancer across the globe. BridgeBio is a great partner, and we are looking forward to continuing our relationship with them through our non-exclusive collaboration framework to propose co-development and co-commercialization opportunities for preclinical precision oncology programs."

"We are expanding our partnership with Helsinn so that even more patients with FGFR-driven cancers will ultimately be able to access infigratinib. Focused execution means reducing the scope of our internal activity. We will continue to advance high-quality programs in our pipeline, while allowing Helsinn to develop and commercialize infigratinib in cancer indications for patients in need," said Neil Kumar, Ph.D., founder and CEO of BridgeBio.

In March 2021, Helsinn and BridgeBio entered into a global license and collaboration agreement to co-commercialize infigratinib for oncology in the U.S. and to co-develop, manufacture and commercialize infigratinib for such indications outside the U.S., excluding mainland China, Hong Kong and Macau. BridgeBio previously entered a strategic collaboration with LianBio for development and commercialization of infigratinib in oncology indications in mainland China, Hong Kong and Macau.

In November 2021, Helsinn and BridgeBio entered into a strategic collaboration to co-develop and co-commercialize a potentially first-in-class inhibitor designed to target glutathione peroxidase 4 (GPX4), which will be investigated in patients with difficult-to-treat tumors. Alongside this, Helsinn and BridgeBio established a new non-exclusive collaboration framework agreement that allows the companies to propose co-development and co-commercialization opportunities for preclinical precision oncology programs. The terms in this strategic collaboration have not changed.

About Infigratinib

Infigratinib is a potent orally administered, selective, ATP‐competitive, kinase inhibitor of FGFRs, with highest affinity for FGFR 1, 2, and 3. The therapy is currently under investigation as a potential first-line treatment for individuals with FGFR2-altered cholangiocarcinoma (bile duct cancer) and in the adjuvant setting for individuals with FGFR3-altered urothelial carcinoma (bladder cancer). Infigratinib is also in development in skeletal dysplasias for the treatment of individuals with FGFR3-altered achondroplasia. BridgeBio retains full rights to develop and commercialize infigratinib in skeletal dysplasias for the treatment of individuals with FGFR3-altered achondroplasia.

About Cholangiocarcinoma (CCA)

CCA represents an aggressive group of malignancies that form in the bile ducts. Although rare in most countries (with a worldwide estimated incidence of <6 per 100,000 people), the incidence of this malignancy is increasing worldwide. Because the disease is usually asymptomatic at early-stages, diagnosis may be delayed until advanced stages, when CCA typically presents as locally advanced or metastatic disease. Despite continuing advances in treatments, the prognosis for this disease remains poor, with a 5-year survival rate of <20%. FGFR2 genetic alterations are present in approximately 15% to 20% of CCA patients and represent potential targets for treatments.1,2

U.S. Indication and Important Safety Information for TRUSELTIQ (infigratinib)

TRUSELTIQ (infigratinib) capsules 25mg/100mg is indicated for the treatment of adults with previously treated, unresectable, locally advanced or metastatic cholangiocarcinoma with a fibroblast growth factor receptor 2 (FGFR2) fusion or other rearrangement as detected by an FDA-approved test.

Accelerated approval was granted based on overall response rate and duration of response. Continued approval for this indication may be contingent upon verification of clinical benefit in confirmatory trial(s).

Warnings and precautions

Ocular toxicity: Retinal pigment epithelial detachment (RPED), which may cause blurred vision, occurred in 11% of 351 patients treated with TRUSELTIQ, including patients with asymptomatic RPED, with a median onset of 26 days.

2021 FULL YEAR Results & Business Updates
"2021 was an exceptional year for HUTCHMED," said Mr. Simon To, Chairman of HUTCHMED. "Commercial success on ELUNATE and the launches of SULANDA and ORPATHYS contributed to an almost four-fold increase in consolidated oncology/immunology revenues to $119.6 million, with momentum continuing in 2022.

ORPATHYS took a major step forward in 2021 with its first approval and important, and as yet unpublished, data from the SAVANNAH study in combination with TAGRISSO. We and our partner AstraZeneca[1] initiated four Phase III studies and one Phase II study, with registration potential, for ORPATHYS during 2021. These actions have triggered $40 million in milestone payments to HUTCHMED since mid-2021. A seventh registration study, a global Phase III in NSCLC[2], the SAFFRON study, is set to initiate in mid-2022.

We are rapidly progressing our plan to expand our oncology assets into global markets. Led by our team of over 800-personnel in discovery, development and manufacturing operations, we have an un-equaled fifteen-year track-record of producing highly quality novel oncology/immunology drug candidates.

Seven of our assets are now being developed outside China. In addition to the global progress of ORPATHYS, surufatinib’s U.S. NDA[3] and EU MAA[4] are in the later stages of regulatory review for advanced NETs; enrollment was completed for fruquintinib in a fourteen-country global Phase III study, the FRESCO-2 study, in CRC[5] which reads-out later in 2022; positive and differentiated POC data was presented for amdizalisib and sovleplenib; and our FGFR[6], IDH1/2[7], ERK[8], third generation BTK[9] and CSF-1R[10] inhibitors all made good progress in early development.

With a strong track record in bringing innovative drugs to patients through rigorous clinical trials, our seasoned clinical team is now enrolling 13 registration studies for six assets with an additional 5 registration studies set to initiate in 2022. With over $1 billion in cash, and the intention to divest further non-core assets, we anticipate having sufficient runway to see our plans through.

Our strategy is to launch a stream of new products in both the China and global markets over the coming years, helping patients with unmet needs and creating value for all our stakeholders."

I. COMMERCIAL OPERATIONS

FULL YEAR 2021 Financial Results
Cash, Cash Equivalents and Short-Term Investments were $1,011.7 million as of December 31, 2021 compared to $435.2 million as of December 31, 2020.

Adjusted Group (non-GAAP[50]) net cash flows excluding financing activities were -$73.5 million (2020: -$78.4m), with the net decrease mainly due to $159.1 million in proceeds from the divestment of HBYS, which offset the increasing Oncology/Immunology R&D spending and lower dividends received from our non-consolidated joint ventures totaling $49.9 million (2020: $86.7m); and
Net cash generated from financing activities totaled $650.0 million (2020: $296.4m) mainly resulting from the global offering of shares and listing on the HKEX in June 2021 and a private placement in April 2021 to a fund affiliated with Baring Private Equity Asia.

Revenues for the year ended December 31, 2021 were $356.1 million compared to $228.0 million in 2020.

Oncology/Immunology consolidated revenues increased 296% (287% at CER) to $119.6 million (2020: $30.2m) resulting from:
ELUNATE revenues increased 168% to $53.5 million (2020: $20.0m) in manufacturing revenues, promotion and marketing service revenues and royalties, as our in-house sales team increased in-market sales 111% to $71.0 million (2020: $33.7m), as provided by Lilly[51];

SULANDA sales revenues of $11.6 million since mid-January 2021 launch, initially approved to treat patients with advanced extra-pancreatic (non-pancreatic) NET and subsequently also approved to treat patients with pancreatic NET in June 2021;

ORPATHYS revenue of $36.3 million since mid-July 2021 launch, which was comprised of a $25.0 million first sale milestone payment and $11.3 million in manufacturing revenues and royalties. AstraZeneca reported $15.9 million in-market sales (2020: nil) of ORPATHYS in 2021; and

Other R&D service fee revenues of $18.2 million (2020: $10.2m), which were primarily fees from AstraZeneca and Lilly for the management of development activities in China.

Other Ventures consolidated revenues increased 20% (13% at CER) to $236.5 million (2020: $197.8m), mainly due to continued sales growth of third-party prescription drug products.

Net Expenses for the year ended December 31, 2021 were $550.7 million compared to $353.7 million in 2020.

Cost of Revenues were $258.2 million (2020: $188.5m), the majority of which were the cost of third-party prescription drug products marketed through our profitable Other Ventures, as well as full year costs associated with ELUNATE, including the provision of promotion and marketing services to Lilly which commenced in October 2020, and the costs for SULANDA and ORPATHYS which commenced commercial sales in 2021;
R&D Expenses were $299.1 million (2020: $174.8m), which increased mainly as a result of an expansion in the active development of eleven novel oncology drug candidates. Our rapidly scaling international clinical and regulatory operations in the U.S. and Europe incurred expenses of $140.1 million (2020: $63.3m), while R&D expenses in China were $159.0 million (2020: $111.5m);
SG&A Expenses[52] were $127.1 million (2020: $61.3m), which increased primarily due to higher staff costs and share-based compensation expense to support rapidly expanding operations. This included the build-up of a large-scale national oncology commercial infrastructure in China and commercial launch readiness in the U.S. to support our oncology products; and
Other Items generated net income of $133.7 million (2020: $70.9m), which increased primarily due to a one-off gain on the divestment of HBYS attributable to the Group of $82.9 million (comprised of a gain of $121.3 million offset in part by related taxes of $14.4 million and amounts attributable to a non-controlling interest of $24.0 million), offset in part by lower one-time land compensation of $5.6 million (2020: $28.8m) recognized for HBYS.

Net Loss attributable to HUTCHMED for the year ended December 31, 2021 was $194.6 million compared to $125.7 million in 2020.

As a result, the net loss attributable to HUTCHMED in 2021 was $0.25 per ordinary share / $1.23 per ADS[53], compared to net loss attributable to HUTCHMED of $0.18 per ordinary share / $0.90 per ADS, in 2020.

"2021 was a transformative year for Arbutus as we greatly expanded our development efforts in Hepatitis B and coronavirus infections, including SARS-CoV-2," said William Collier, Arbutus’ President and Chief Executive Officer. "We formed strategic and clinical partnerships that allowed us to explore several combination therapies with AB-729, our RNAi therapeutic, as a potential cornerstone agent in a functional cure for Hepatitis B, expand the reach of AB-729 to greater China and broaden our pipeline to include programs targeting coronaviruses. In addition, we have expanded our preclinical programs in HBV with our oral PD-L1 inhibitor, AB-101, and our oral RNA destabilizer, AB-161, both of which are expected to complete IND-enabling studies this year. Multiple key clinical trial data read-outs expected later this year for AB-729 and AB-836 will inform our go-forward clinical and regulatory strategy for HBV Phase 2b development."

Pipeline Update

AB-729 (RNAi Therapeutic)

Arbutus is currently dosing patients in the last cohort of its Phase 1a/1b clinical trial to evaluate the safety and tolerability of AB-729 in patients with chronic Hepatitis B (cHBV) infection (AB-729-001 Trial). Data observed to-date show that AB-729 continues to reduce HBsAg across all doses and dosing intervals with a favorable safety and tolerability profile. Additionally, long term dosing of AB-729 has increased HBV-specific immune responses in some patients.
The Company intends to present updated and new on-treatment data on multiple cohorts of patients included in the AB-729-001 Trial, as well as long-term follow-up data for patients in the AB-729-001 Trial who completed treatment and have discontinued AB-729 and standard-of-care nucleos(t)ide analogues (NA) therapy at a medical conference this year.
In-line with the Company’s strategy to combine multiple therapies that target different points of the viral replication cycle to develop a curative treatment regimen for cHBV, Arbutus is currently enrolling patients in its Phase 2a randomized, open-label, proof-of-concept clinical trial designed to evaluate the safety and tolerability of AB-729 in combination with ongoing NA therapy and short courses of PEG-IFNα-2a in 40 patients with cHBV infection. The Company is expecting initial data from this clinical trial in the second half of 2022.
Also, in line with the Company’s strategy, Arbutus has entered into separate clinical collaboration agreements with Assembly Biosciences, Inc. (Assembly), Vaccitech plc (Vaccitech) and Antios Therapeutics, Inc. (Antios) to evaluate AB-729 as the cornerstone agent in combination with Assembly’s capsid inhibitor, Vaccitech’s T-cell stimulating therapeutic vaccine, and Antios’ Active Site Polymerase Inhibitor Nucleotide (ASPIN), respectively, in patients with cHBV infection.
Enrollment is on-going in the Phase 2a proof-of-concept triple combination clinical trial evaluating AB-729, vebicorvir (VBR), Assembly’s lead HBV core inhibitor (capsid inhibitor), and an NA. Assembly is conducting this clinical trial and expecting initial data in the second half of 2022.
Arbutus is on-track to initiate a triple combination Phase 2a clinical trial in the first half of 2022 to evaluate AB-729, combined with VTP-300, Vaccitech’s therapeutic vaccine and an NA.
Enrollment is complete in a cohort of patients in Antios’ Phase 2a clinical trial evaluating AB-729, ATI-2173, Antios’ ASPIN, and Viread (tenofovir disoproxil fumarate). With the majority of patients in this cohort enrolled in Ukraine, which is currently in a state of war, they may be lost to follow-up before completing the trial. Therefore, Arbutus and Antios may report limited data on a reduced number of patients from this clinical trial.
AB-836 (Oral Capsid Inhibitor)

AB-836 is Arbutus’ novel, next generation oral capsid inhibitor with improved intrinsic potency, activity against resistant variants and an enhanced ability to starve replenishment of cccDNA, which is responsible for HBV persistence.
Arbutus is enrolling patients in part 3 of its on-going Phase 1a/1b clinical trial evaluating the safety and tolerability of multiple doses of AB-836 in patients with cHBV infection. The Company is on-track to report additional data from patients with cHBV infection in the first half of 2022.
AB-101 (Oral PD-L1 Inhibitor)

AB-101 is Arbutus’ oral PD-L1 inhibitor that is designed to reawaken the immune system, which the Company believes may be a key component in developing a functional cure for HBV.
Arbutus has commenced IND-enabling studies for AB-101 and intends to complete those studies in the second half of 2022.
AB-161 (Oral RNA destabilizer)

AB-161 is Arbutus’ next-generation oral HBV specific RNA destabilizer, which is being developed to create an all-oral treatment regimen to functionally cure HBV.
Arbutus has conducted extensive non-clinical safety evaluations with AB-161 that provide confidence in the molecule’s ability to circumvent the peripheral neuropathy findings seen in non-clinical safety studies with the Company’s first-generation oral RNA destabilizer, AB-452.
Arbutus has commenced IND-enabling studies for AB-161 and intends to complete those studies in the second half of 2022.
COVID-19 and Pan-Coronavirus Programs

Leveraging its extensive antiviral drug discovery experience, Arbutus is focused on the discovery and development of new pan-coronavirus molecular entities to treat COVID-19 and future coronavirus outbreaks by targeting essential viral proteins including the nsp12 viral polymerase and the nsp5 viral protease.
Arbutus intends to nominate a candidate that inhibits the SARS-CoV-2 nsp5 main protease (Mpro) in the first half of 2022 and advance that candidate into IND-enabling studies. In addition, the Company intends to continue lead optimization activities for an Nsp12 viral polymerase candidate.
Corporate Update

In April 2018, Arbutus entered into an agreement with Roivant Sciences Ltd. (Roivant), its largest shareholder, to launch Genevant Sciences Ltd. (Genevant), a company focused on a broad range of RNA-based therapeutics enabled by Arbutus’ LNP and ligand conjugate delivery technologies. Arbutus licensed rights to its LNP and ligand conjugate delivery platforms to Genevant for RNA-based applications outside of HBV, except to the extent certain rights had already been licensed to other third parties. Arbutus retained all rights to its LNP and conjugate delivery platforms for HBV and owns approximately 16% of the common equity of Genevant.

In February 2022, Arbutus and Genevant filed a lawsuit in the U.S. District Court for the District of Delaware against Moderna, Inc. and a Moderna affiliate seeking damages for infringement of U.S. Patent Nos. 8,058,069, 8,492,359, 8,822,668, 9,364,435, 9,504,651, and 11,141,378 in the manufacture and sale of MRNA-1273, Moderna’s vaccine for COVID-19. The patents relate to nucleic acid-lipid particles and lipid vesicles, as well as compositions and methods for their use. Arbutus, and Genevant, do not seek an injunction or otherwise seek to impede the sale, manufacture or distribution of MRNA-1273. However, the parties seek fair compensation for Moderna’s use of their patented technology that was developed with great effort and at a great expense, without which Moderna’s COVID-19 vaccine would not have been successful.

Under the license agreement with Genevant, as amended, if Genevant receives proceeds from an action for infringement by any third parties of Arbutus’ intellectual property licensed to Genevant, Arbutus would be entitled to receive, after deduction of litigation costs, 20% of the proceeds received by Genevant or, if less, tiered low single-digit royalties on net sales of the infringing product (inclusive of the proceeds from litigation or settlement, which would be treated as net sales).
Financial Results

Cash, Cash Equivalents and Investments

As of December 31, 2021, the Company had cash and cash equivalents of $109.3 million and investments in marketable securities of $81.7 million, totaling $191.0 million, as compared to $123.3 million as of December 31, 2020. The ending cash, cash equivalents and marketable securities as of December 31, 2021 do not include a $40 million upfront payment and a $15 million equity investment from Qilu Pharmaceutical as part of an exclusive licensing agreement and strategic partnership to develop and commercialize AB-729 in China, received in January 2022.

During the year ended December 31, 2021, Arbutus used $67.5 million in operating activities, which was offset by $134.7 million of net proceeds from the issuance of common shares under Arbutus’s "at-the-market" offering program. Arbutus expects a net cash burn between $90 to $95 million in 2022 and believes its cash runway, including $55 million of gross proceeds received from Qilu Pharmaceutical in January 2022, will be sufficient to fund the Company’s operations into the second quarter of 2024.

Net Loss

For the year ended December 31, 2021, the Company’s net loss attributable to common shares was $88.4 million, or a loss of $0.83 per basic and diluted common share, as compared to a net loss of $75.9 million, or a loss of $1.00 per basic and diluted common share, for the year ended December 31, 2020. Net loss attributable to common shares for the year ended December 31, 2021 and 2020 included $12.1 million of non-cash expense in both periods for the accrual of coupon on the Company’s convertible preferred shares, which converted into 22.8 million common shares in October 2021.

Operating Expenses

Research and development expenses were $65.5 million for the year ended December 31, 2021 compared to $49.3 million for the same period in 2020. The increase of $16.2 million in research and development expenses for the year ended December 31, 2021 versus the same period in 2020 was due primarily to an increase in expenses related to the Company’s multiple, ongoing AB-729 clinical trials, including its collaboration with Assembly, an increase in expenses for its ongoing AB-836 Phase 1a/1b clinical trial, and an increase in expenses for its early stage development programs, including its coronavirus programs.

Outstanding Shares

As of December 31, 2021, the Company had approximately 145.0 million common shares issued and outstanding, as well as approximately 11.4 million stock options outstanding. Following the conversion of preferred shares in October 2021, Roivant owned approximately 27% of the Company’s outstanding common shares as of December 31, 2021.

COVID-19 Impact

The COVID-19 virus, first identified in December 2019, 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 and patients 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 materially impact our plans and timelines in the future.

About AB-729

AB-729 is an RNA interference (RNAi) therapeutic specifically designed to reduce all HBV viral proteins and antigens, including hepatitis B surface antigen, which is thought to be a key prerequisite to enable reawakening of a patient’s immune system to respond to the virus. AB-729 targets hepatocytes using Arbutus’ novel covalently conjugated N-acetylgalactosamine (GalNAc) delivery technology that enables subcutaneous delivery. Clinical data generated thus far has shown single- and multi-doses of AB-729 to be generally safe and well-tolerated while providing meaningful reductions in hepatitis B surface antigen and hepatitis B DNA. AB-729 is currently in multiple Phase 2a clinical trials.

About AB-836

AB-836 is a next generation oral hepatitis B virus (HBV) capsid inhibitor that interacts with HBV core protein, which in turn is required for viral replication. The current standard-of-care therapy for HBV is primarily nucleos(t)ide analogues that inhibit the viral polymerase and significantly reduce, but do not eliminate viral replication. AB-836 in combination with nucleos(t)ide analogues is designed to completely eliminate viral replication in infected cells by preventing the assembly of functional viral capsids. In addition, AB-836 has been shown to inhibit the replenishment of covalently closed circular DNA (cccDNA), the viral genetic reservoir which the virus needs to replicate itself. Preliminary data from an on-going Phase 1a/1b clinical trial has shown that AB-836 is generally safe and well-tolerated and provides robust antiviral activity.

About HBV

Hepatitis B is a potentially life-threatening liver infection caused by the hepatitis B virus (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 290 million people worldwide suffer from chronic HBV infection, while other estimates indicate that approximately 2.4 million people in the United States suffer from chronic HBV infection. Approximately 820,000 people die every year from complications related to chronic HBV infection despite the availability of effective vaccines and current treatment options.
