(“Vir”, Nasdaq: VIR). VIR-3434 grows the Company’s leading clinical pipeline of therapeutic candidates for hepatitis B virus (HBV) and expands its set of potential combination treatment options to explore as part of its effort to develop a functional cure for HBV.
  • Brii Bio was added to the MSCI China Small Cap Index in May2022. The MSCI China Small Cap Index is an equity index compiled by MSCI Inc., a leading provider of critical decision support tools and services for the global investment community. The index is designed to measure the performance of the China market’s small-cap segment and is widely recognized by the international financial community as a benchmark for global institutional investors seeking to optimize their investment portfolios.
  • We sponsored the 20/20 Mom Annual Forum, Maternal Mental Health Now, 35th Annual Postpartum Support International Conference and the 2022 Black Maternal & Mental Health Summit. Our participation in these events help the Company foster relationships with patients, their caregivers, and the disease-specific nonprofit groups that support them. We believe this is an important step to ensure patient voices are understood across every function, from R&D to commercialization.

2022 Interim Pipeline Highlights and Upcoming Data Readouts

Hepatitis B Virus (HBV) Functional Cure Program (China team core project)

We are progressing multiple combination studies for the treatment of HBV led by our team in China and our partner Vir Biotechnology (“Vir,” Nasdaq: VIR).

BRII-179 (VBI-2601) and BRII-835 (VIR-2218) (therapeutic vaccine and siRNA) Combination

  • In February 2022, we completed the enrollment of 90 patientsfrom the Asia-Pacific region in our Phase 2 multi-regional clinical trial (MRCT) combination study of BRII-179 (VBI-2601)/BRII-835 (VIR-2218).
  • Patients are expected to complete treatment in the Phase 2MRCT combination therapy study in the third quarter of 2022, with interim topline data expected by the end of 2022.
  • If positive results are achieved in the combination study, weplan to initiate a pre Investigational New Drug (“pre-IND”) discussion with China’s Center for Drug Evaluation (“CDE”) in 2023 for a pivotal study with our combination BRII-179 (VBI-2601)/BRII-835 (VIR-2218) therapy.

BRII-179 (VBI-2601) and PEG-IFN-α Combination

  • A two-part Phase 2a/2b combination study with BRII-179(VBI-2601) in HBV patients receiving pegylated interferon alfa (“PEG-IFN-α”) and nucleotide/nucleoside reverse transcriptase inhibitors (NRTI) treatment is currently recruiting patients in China.
  • Patient enrollment for part one of the Phase 2 study (Phase2a with approximately 120 patients) is expected to be complete in the fourth quarter of 2022 with interim topline results expected in the first half of 2023.

BRII-835 (VIR-2218)

  • In March 2022, we presented findings from the Phase 2 Chinastudy on the safety and antiviral activity of BRII-835 (VIR-2218) administered on top of nucleos(t)ide analog therapy at the 2022 Asian Pacific Association for the Study of the Liver (APASL) conference. The dose-dependent reduction in serum HBsAg observed in both HBeAg- and HBeAg+ Chinese chronic HBV patients in this trial after two doses of BRII-835 (VIR-2218) is consistent with previous findings demonstrated in other racial/ethnic groups.
  • Our partner, Vir Biotechnology presented data at theInternational Liver Congress in June 2022, showing longer treatment duration of monthly BRII-835 (VIR-2218) results in deeper and more sustained reductions in hepatitis B surface antigen (HBsAg) in participants with chronic hepatitis B infection.
  • Additional data from the Phase 2 study of BRII-835 (VIR-2218)in combination with PEG-IFN-α led by Vir is expected in 2022.

BRII-877 (VIR-3434) (Study conducted by Vir)

  • Data from a Phase 1 monotherapy study led by Vir were presentedat the International Liver Congress in June 2022 demonstrating the dose-dependent durability of HBsAg reductions following administration of a single dose of BRII-877 (VIR-3434).
  • In virally suppressed participants with HBsAg of less than3,000 IU/mL, a single 6 mg to 75 mg dose of BRII-877 (VIR-3434) resulted in rapid HBsAg reductions of greater than 1 log10 IU/mL in most participants. Single doses of BRII-877 (VIR-3434) showed no clinically significant safety signals; all adverse events (AEs) were Grade 1 or 2. These data support the potential for BRII-877 (VIR-3434) to provide a meaningful role in the functional cure of chronic HBV infection.
  • In July 2022, we announced thatthe Company exercised its option to in-license BRII-877 (VIR-3434) for exclusive development and commercialization rights in Greater China as part of its broader collaboration with Vir.
  • We plan to request a pre-IND meeting with China’s CDE for aPhase 1 study of BRII-877 (VIR-3434) by the end of 2022.

BRII-835 (VIR-2218) and BRII-877 (VIR-3434) (siRNA and antibody combination conducted by Vir)

  • Our partner, Vir, shared encouraging data from Part A of itsPhase 2 MARCH study in April 2022, which suggests that BRII-835 (VIR-2218) and BRII-877 (VIR-3434) are additive in reducing HBsAg, with no drug-related safety signals reported to date.
  • Additional data from the first cohort (Part A) of the Phase 2MARCH study evaluating safety, pharmacokinetics and HBsAg suppression of BRII-835 (VIR-2218) and BRII-877 (VIR-3434) combination is expected later this year.
  • Part B of the Phase 2 MARCH trial initiated in the secondquarter of 2022 is to evaluate additional cohorts to determine dose, length of treatment, and evaluate triple cocktails with PEG-IFN-α, when BRII-877 (VIR-3434) is given every 4 weeks.

COVID-19 Program (Internally discovered. China team core project)

  • We completed a Phase 2 study of amubarvimab/romlusevimabcombination therapy (formerly BRII-196 and BRII-198 combination therapy) led by Prof. Nanshan Zhong as the lead principal investigator. Data demonstrated that the combination therapy is generally safe and well-tolerated in both severe and non-severe Chinese patients with COVID-19. Favorable efficacy profiles were observed, consistent with the results observed in the ACTIV-2 study.
  • As COVID-19 continues to evolve, we completed a neutralization activity evaluation on Omicron variants using live virus and pseudo Virus-Like Particles (VLPs) expressing the full-length spike protein of Omicron subvariants and available authentic Omicron viruses. The testing data from multiple independent laboratories demonstrate that the Company’s long-acting amubarvimab/romlusevimab combination retains neutralizing activity against all previous variants of concern (VOC) and Omicron subvariants, including the following commonly identified ones, B.1.1.7 (Alpha), B.1.351 (Beta), P.1 (Gamma), B.1.429 (Epsilon), B.1.617.2 (Delta), AY.4.2 (Delta Plus), C.37 (Lambda), B.1.621 (Mu), B.1.1.529 (Omicron), as well as Omicron subvariants BA.1.1, BA.2 , BA.2.12.1 and BA.4/5.
  • The long-acting amubarvimab/romlusevimabcombination therapy was added to the COVID-19 Diagnosis and Treatment Guidelines (9th Pilot Edition) in March 2022 by the National Health Commission of China.

2022 Interim Financial Results

  • Other Income was RMB38.2million for the six months ended June 30, 2022, representing a decrease of RMB8.1 million, or 17.4%, compared with RMB46.3 million for the six months ended June 20, 2021. The decrease was mainly due to the decreased income recognized from confirmed PRC government grants of RMB17.8 million. The decrease was partially offset by the increase in bank interest income of RMB9.7 million attributable to the increased bank and cash balances after our initial public offering.
  • Research and development expenses were RMB258.5 million for the six months ended June 30, 2022, representing an increase of RMB100.9 million, or 64.0%, compared with RMB157.6 million for the six months ended June 30, 2021. The increase was primarily due to the increase in third party contracting fees, as well as employee costs, for our continuous development in clinical trials.
  • Administrative expenses were RMB95.5 million for the six months ended June 30, 2022, representing anincrease of RMB27.5 million, or 40.4%, compared with RMB68.0 million for the six months ended June 30, 2021. The increase was primarily attributable to the increase in employee headcount.
  • We established a streamlinedcommercial team to better support the launch and distribution of our amubarvimab/romlusevimab combination therapy. As a result, we started to incur selling and marketing expenses, which primarily comprise employee-related costs and prelaunch activity expenses associated with product commercialization.
  • Total comprehensive expense for the six months ended June 30, 2022 wasRMB217.7 million, representing a decrease of RMB2,703.8 million, or 92.5%, compared with RMB2,921.5 million for the six months ended June 30, 2021. The decrease was primarily due to the decrease in fair value loss on financial liabilities at FVTPL.

About Our Programs

HBV (Licensed from VBI Vaccines Inc. (VBI) and Vir Biotechnology, Inc. (Vir). China team core project)

To treat HBV, we are currently developing BRII-179 (VBI-2601), an HBV-specific B cell and T cell immunotherapeutic vaccine candidate, BRII-835 (VIR-2218), an investigational HBV-targeting siRNA, which has the potential to stimulate an effective immune response and has shown direct antiviral activity against HBV, and the newly in-licensed BRII-877 (VIR-3434), an investigational subcutaneously administered HBV-neutralizing monoclonal antibody. We hold exclusive rights in Greater China to develop and commercialize BRII-179 (VBI-2601), BRII-835 (VIR-2218) and BRII-877 (VIR-3434).

BRII-179 (VBI-2601) is a novel recombinant protein-based HBV immunotherapeutic candidate that builds upon the 3-antigen conformation of VBI’s prophylactic HBV vaccine candidate, with a Th-1 enhancing adjuvant to induce both B-cell and T-cell immune responses.

BRII-835 (VIR-2218) is an investigational subcutaneously administered HBV-targeting siRNA that has the potential to stimulate an effective immune response and have direct antiviral activity against HBV. It is the first siRNA in the clinic to include Enhanced Stabilization Chemistry Plus technology to enhance stability and minimize off-target activity, which potentially can result in an increased therapeutic index.

BRII-877 (VIR-3434) is an investigational subcutaneously administered HBV-neutralizing monoclonal antibody designed to block entry of all 10 genotypes of HBV into hepatocytes and also to reduce the level of virions and subviral particles in the blood. BRII-877 (VIR-3434), which incorporates Xencor’s Xtend™ and other Fc technologies, has been engineered to potentially function as a T cell vaccine against HBV in infected patients, as well as to have an extended half-life.

COVID-19 (Discovered in collaboration with Tsinghua University and Third People’s Hospital of Shenzhen through our subsidiary, TSB Therapeutics Ltd (Beijing) Co. Limited. China team core project)

Amubarvimab and romlusevimab are non-competing SARS-CoV-2 monoclonal neutralizing antibodies derived from convalesced COVID-19 patients. They have been specifically engineered to reduce the risk of antibody-dependent enhancement and prolong the plasma half-lives for potentially more durable treatment effect.

Approved by the China’s NMPA in December 2021, our long-acting amubarvimab/romlusevimab cocktail therapy is approved to be administered by intravenous infusion in two sequential doses for the treatment in adults and pediatric patients (age 12-17 weighing at least 40 kg) of mild- and normal-type COVID-19 at high risk for progression to severe disease, including hospitalization or death. The indication of pediatric patients (age 12-17 weighing at least 40 kg) is under a conditional approval. In March 2022, the National Health Commission of China included the amubarvimab/romlusevimab combination in its COVID-19 Diagnosis and Treatment Guidelines (9th Edition) for the treatment of COVID-19. The live virus testing data as well as pseudovirus testing data from multiple independent labs have demonstrated that the long-acting amubarvimab/romlusevimab combination retains activity against major SARS-CoV-2 variants of concern, including the following commonly identified variants, B.1.1.7 (Alpha), B.1.351 (Beta), P.1 (Gamma), B.1.429 (Epsilon), B.1.617.2 (Delta), AY.4.2 (Delta Plus), C.37 (Lambda), B.1.621 (Mu), B.1.1.529 (Omicron), as well as Omicron subvariants BA.1.1, BA.2 , BA.2.12.1 and BA.4/5.

Postpartum Depression (PPD)/Major Depressive Disorder (MDD)/Other depressive disorders (Internally discovered. U.S. team core project)

We are developing BRII-296 and BRII-297 to address the challenges associated with current treatments for PPD, MDD, and other anxiety or depressive disorders. We are doing this by leveraging insight gained from, and applied drug formulation know-how utilized in developing long-acting therapies, where drug administration convenience and patient compliance are critical to potential treatment success.

BRII-296 is our novel and single treatment option for the treatment and prevention of PPD. It acts as a gamma-aminobutyric acid A (GABAa) receptor positive allosteric modulator. BRII-296 is in clinical Phase 1 study.

BRII-297 is a new chemical entity discovered internally. BRII-297 is under development for treatment of various anxiety and depression disorders.

HIV (Internally discovered. U.S. team core project)

We are developing BRII-778 and BRII-732 as a once-weekly single-tablet combination therapy that will offer a more discreet, convenient, and non-invasive maintenance therapy for HIV patients.

BRII-778 is an extended-release formulation of an FDA-approved NNRTI, Edurant (rilpivirine hydrochloride). Edurant, an instant-release formulation of rilpivirine, has exhibited antiviral activity against a broad panel of HIV’s most common strains. BRII-778, like all NNRTIs, binds to the NNRTI binding site, a flexible allosteric pocket located at a site adjacent to the DNA polymerizing processing site, resulting in conformational changes, and altered function of reverse transcriptase.

BRII-732 is a new chemical entity (NCE) that is metabolized upon oral administration into EFdA or islatravir. EFdA functions not only as a potent chain-terminator like other NRTIs, but also as a potent HIV reverse transcriptase translocation inhibitor (NRTTI), with high binding affinity to the active site of RT, that inhibits HIV reverse transcriptase by blocking translocation of nascently synthesized strand(s) for the next nucleotide incorporation.

Multidrug- and Extensively Drug-Resistant (MDR/XDR) Gram-negative Infections (licensed from Qpex Biopharma, Inc. (Qpex). China team core project)

We are developing our MDR/XDR therapies in collaboration with our partner Qpex as part of their global development plan. We retain responsibility for the development and regulatory activities in Greater China, while Qpex is responsible for all development and regulatory activities outside Greater China. Qpex is progressing BRII-636, BRII-672, and BRII-693 in parallel with a goal of moving each to global Phase 3 studies when we are expected to join with China as part of the global studies. BRII-636, BRII-672, and BRII-693 candidates all obtained QIDP designation from the U.S. FDA, which may receive incentives in the future. We are collaborating with Qpex to progress OMNIvance® (BRII-636, a broad spectrum BLI, in combination with an IV β-lactam antibiotic), ORAvanceTM (BRII-672, a broad spectrum oral BLI in combination with an oral β -lactam antibiotic)and BRII-693 (a novel synthetic IV lipopeptide antibiotic) for the treatment of bacterial infections, for which there are critical needs for new antibiotics treatments.

BRII-636 (BLI of OMNIvance®is a novel cyclic boronic acid derived broad-spectrum inhibitor designed to cover all major SBLs and MBLs to restore the bacterial activity of multiple carbapenems and cephalosporins. It is administered by the IV route.

BRII-672 (BLI of ORAvance™) is a prodrug of BRII-636 that can be administered orally to deliver BRII-636 into the bloodstream. These agents were discovered by our partner Qpex as part of their expertise in BLIs, using the boron atom as a part of its pharmacophore.

BRII-693 (QPX-9003) is a novel synthetic lipopeptide, which has emerged as a development candidate based on a combination of increased in vitro and in vivo potency, and an improved safety profile compared to currently available polymyxins. BRII-693 has the potential to represent a significant advancement in the polymyxin class of hospital (IV) antibiotics.

MDR/XDR Mycobacterium Tuberculosis (TB) and Nontuberculoous Mycobacteria (NTM) Program (licensed from AN2 Therapeutics, Inc. (AN2). China team core project)

We are developing epetraborole (BRII-658) in MDR/XDR TB and NTM with AN2. Epetraborole (BRII-658) is a novel antibiotic that has shown potent and broad-spectrum activity against mycobacteria and other bacterial pathogens in Phase 1b trials. AN2 is conducting a pivotal Phase 2/3 clinical trials of epetraborole (BRII-658) for the treatment of treatment-refractory Mycobacterium avium complex (MAC) lung disease. We hold a license to develop, manufacture, and commercialize epetraborole (BRII-658) in Greater China.

BRII-658 (epetraborole) is an antibiotic with a novel mechanism of action. It is a boron-containing, orally available, small molecule inhibitor of mycobacterial leucyl-tRNA synthetase, or LeuRS, an enzyme that inhibits protein synthesis.
