ROCKVILLE,Md. and SEOUL,South Korea,April 28,2023 -- HanAll Biopharma Co.,Ltd. (KRX: 009420. KS),a global biopharmaceutical company committed to discovering and developing innovative medicines for patients,reported financial results for the first quarter and provided business updates.

HanAll's financial data demonstrated a strong momentum in the start of 2023,with revenues of KRW 28.8 billion,representing a 20 percent sales growth mainly driven by pharmaceutical sales from the first quarter of 2022. The company reported a net loss of 1.3 billion won due to continued investment in R&D.

Following the previous statement from the 2022 full-year financial report,HanAll expects to secure top-line data from the tanfanercept Phase 3 clinical study in dry eye disease in the first half of 2023 and plans to initiate a Phase 3 clinical study of batoclimab in generalized myasthenia gravis (gMG) in Japan this year.

"The recent positive top-line result from gMG Phase 3 study by Harbour BioMed suggests the potential of batoclimab as the first anti-FcRn treatment to be commercialized in China,reinforcing our confidence to develop batoclimab in an array of autoimmune diseases. With a strong focus on collaboration and innovation,we will continue to push forward with our R&D programs to deliver groundbreaking medicines that will make a difference in the patients' lives," said Sean Jeong,M.D.,MBA,CEO of HanAll Biopharma.

First Quarter 2023 BUSINESS UPDATE

Pipeline Development Highlights

A comprehensive update of HanAll's pipeline development below includes an overview of research along with lists of compounds and targeted indications,along with developmental phase.

AUTOIMMUNE DISEASES PROGRAMS

Batoclimab(HL161BKN)

A novel,fully human,subcutaneously administered antibody targeting FcRn,with the potential to address multiple IgG-mediated autoimmune diseases. Batoclimab is designed to selectively bind to and inhibit FcRn,which plays a role in recycling IgG,thus leading to a reduction in IgG antibodies.

Harbour BioMed,a licensed partner of HanAll in China,announced the first positive Phase 3 top-line results for batoclimab in generalized myasthenia gravis (gMG) subjects in March 2023. Data from the trial met the primary endpoint as well as key secondary endpoints. Batoclimab treatment was also found to be overall safe and well-tolerated,without any new significant safety signals identified. Harbour BioMed plans to submit a Biologics License Application (BLA) to the National Medical Products Administration (NMPA) for batoclimab together with its sub-licensee CSPC NBP Pharmaceuticals Co.,Ltd. (NBP Pharma),a wholly-owned subsidiary of CSPC Pharmaceutical Group Limited (CSPC Pharmaceutical),based on the study results. Batoclimab is also being developed for study in China in an array of other autoimmune disorders including thyroid eye disease (TED).

HanAll is progressing towards initiation of a Phase 3 clinical study of batoclimab in gMG in Japan this year. Additionally,HanAll is exploring options for developing batoclimab in TED and chronic inflammatory demyelinating polyneuropathy (CIDP) in Japan.

Another licensed partner,Immunovant in the U.S. and Europe,is conducting global Phase 3 trials with batoclimab in gMG and TED. Additionally,the initial data readout for a Phase 2 trial in Grave's disease (GD) is anticipated in the second half of 2023 and an initial Phase 2b results in CIDP is expected in the first half of 2024.

HL161ANS

Another novel,subcutaneous antibody molecule that inhibits FcRn-mediated recycling of IgG,designed to deliver maximum lgG reductions while minimizing interference with albumin recycling.

Immunovant anticipates initial results from a Phase 1 trial for HL161ANS,a new FcRn inhibitor (Immunovant project designation: IMVT-1402),in the second half of 2023. Immunovant also plans to evaluate HL161ANS in multiple autoimmune diseases, based on strategic portfolio considerations.

OPHTHALMIC DISEASE PROGRAMS

Tanfanercept (HL036)

A novel topical protein therapy for ophthalmic diseases,including dry eye disease (DED),which inhibits TNF alpha,a key mediator of ocular inflammation

HanAll Biopharma and Daewoong Pharmaceutical are progressing with the second Phase 3 (VELOS-3) study in the U.S. in subjects with moderate to severe DED to examine the safety and efficacy of tanfanercept. Study enrollment is complete and the top-line results from the VELOS-3 study are expected in the first half of 2023.

Harbour BioMed,closed its Phase 3 China study in DED,based on the Independent Data Monitoring Committee's (IDMC) evaluation of the efficacy data from the second interim analysis. The HanAll U.S. study (VELOS-3) differs from the Harbour Chinese study in a number of ways including key inclusion criteria,primary endpoints,as well as subject demographics. The future development plans for tanfanercept in China are under discussion.ONCOLOGY PROGRAMS

HL187/ HL186Monoclonal antibodies that respectively target T cell immunoreceptors with Ig and ITIM {Immunoreceptor tyrosine-based inhibitory motif} domains (TIGIT) and T cell immunoglobulin and mucin domain-3 (TIM-3) are being developed in collaboration with Daewoong Pharmaceutical. as potential oncology treatmentsHanAll is continuing with the pre-clinical development of HL187 asset and plans to evaluate the further development of HL186 based on the strategic portfolio review.FINANCIAL HIGHLIGHTS (CONSOLIDATED)
