"HanAll made a meaningful progress in our R&D in the second quarter, including the completion of the HL192 Phase 1 study in PD, the initiation of the VELOS-4 Phase 3 study for dry eye, and the establishment of a licensing agreement with Turn.bio to develop medicines for age-related diseases. We will sustain our investment in R&D through enhancing efficiency of our operations," said Sean Jeong, M.D., MBA, CEO of HanAll Biopharma.

Second Quarter 2024 BUSINESS UPDATE

Pipeline Development Highlights

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

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 FcRn, which plays a role in recycling IgG, thereby reducing levels of harmful IgG antibodies

• Immunovant, a member of the Roivant group of companies as well as HanAll's licensed partner in the United States and Europe, is making progress across four autoimmune indications. Results from the batoclimab study in Graves' disease are expected in fall of 2024 from Immunovant. Phase 3 studies in gMG and TED are advancing.

• Topline data from the Phase 3 study in generalized Myasthenia Gravis (gMG) is also anticipated in the first quarter of 2025.

• Progress continues in the Phase 3 study for Thyroid Eye Disease (TED), with the top-line results also projected in the first half of 2025.

• Regarding the ongoing Phase 2b Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) study, Immunovant has decided to extend the duration of the study in order to optimize the study design for IMVT-1402 in CIDP. Following this decision, initial results from period 1 of the Phase 2b study in CIDP are expected in the first quarter of 2025.

• Harbour BioMed, another licensed partner which transferred exclusive rights to develop, manufacture, and commercialize batoclimab in the Greater China region to CSPC NBP Pharmaceuticals Co., Ltd. (NBP Pharma), has resubmitted the Biologics License Application (BLA) for batoclimab to the National Medical Products Administration (NMPA) in June 2024. The BLA incorporated supplementary long-term safety data from the Phase 3 study in gMG, concluded in June 2023.

HL161ANS (IMVT-1402)

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

• Immunovant plans to initiate 4 to 5 potentially registrational studies for IMVT-1402 (HL161ANS) before the end of first quarter of 2025, following a recent Type B meeting with the FDA (Food and Drug Administration). The company plans to initiate studies on IMVT-1402 in a total of 10 indications before the end of the first quarter of 2026.

• Immunovant is exploring initiating a registrational development in gMG with IMVT-1402.

• Immunovant will work to optimize the HL161ANS/IMVT-1402 CIDP trial design, drawing insights from the ongoing CIDP Phase 2b trial for batoclimab. This process involves extending the duration of Phase 2b study in batoclimab in CIDP and incorporating learnings from the previous studies.

• Immunovant also plans to provide an overview of the development program for HL161ANS/IMVT-1402 in Grave's disease (GD) in the second half of 2024.

OPHTHALMIC DISEASE PROGRAM

Tanfanercept (HL036)

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

• HanAll Biopharma and Daewoong Pharmaceutical initiated the Phase 3 VELOS-4 study to evaluate the efficacy and safety of tanfanercept in dry eye. The topline results for the VELOS-4 study is expected in 2026.

• The Phase 3 VELOS-4 trial builds upon key insights gained from the completed Phase 3 VELOS-3 study. In VELOS-3, tanfanercept demonstrated a statistically significant improvement in the secondary efficacy endpoint of tear volume, as measured by unanesthetized Schirmer testing, in patients treated with tanfanercept compared to those in the vehicle group at week 8 (p=0.002). In addition, a post hoc analysis revealed that a notable proportion of participants in the tanfanercept group (14%) showed significant improvement (p=0.011) in the Schirmer test, with an increase of at least 10mm from baseline at week 8, compared to only 4% in the vehicle group.

• The 2020 FDA Draft Guidance on Dry Eye Drug Development considers the proportion of participants achieving a minimum 10mm increase in the Schirmer test response rate as an acceptable primary efficacy endpoint for approval.

NEUROLOGY PROGRAM

HL192 (ATH-399A)

A pipeline candidate from NurrOn Pharmaceuticals (originating from Harvard Medical School's Molecular Neurobiology Laboratory) which targets Nurr1, both a master regulator in dopaminergic neuron development and maintenance, as well as an important component in anti-inflammatory functions. HL192 (ATH-399A) is being developed to treat neurodegenerative diseases, including Parkinson's disease (PD).

• The Phase 1 study of HL192, being jointly developed by HanAll Biopharma, Daewoong Pharmaceutical, and NurrOn Pharmaceuticals, has completed dosing with the results expected in the second half of 2024.

ONCOLOGY PROGRAMS

HL187 is a monoclonal antibody that targets TIGIT (T cell immunoreceptors with Ig and ITIM domains {Immunoreceptor tyrosine-based inhibitory motif domains}). HL186 is a monoclonal antibody that targets TIM-3 (T cell Ig and mucin domain-3). These antibodies are being developed in collaboration with Daewoong Pharmaceutical as potential oncology treatments.

• HanAll is continuing with the pre-clinical development of the HL187 (anti-TIGIT) asset and plans to evaluate the further development of HL186 (anti-TIM-3) based on the strategic portfolio review.
