FIRST QUARTER 2022 BUSINESS UPDATE

HL161 (INN: batoclimab):A novel,fully human,anti-FcRn antibody developed as a subcutaneous injection for the treatment of rare autoimmune diseases mediated by pathogenic IgG antibodies. It is being developed in the US and China respectively by global license partners Immunovant and Harbour BioMed.

Harbour BioMed is developing batoclimab in six autoimmune indications including myasthenia gravis (MG),immune thrombocytopenia (ITP),neuromyelitis optica spectrum disorder (NMOSD),thyroid eye disease (TED),chronic inflammatory demyelinating polyneuropathy (CIDP),and pemphigus vulgaris (PV). Harbour is undergoing a pivotal Phase 3 trial in MG,and is progressing towards Biologics License Application (BLA) submission. The clinical trial on TED is currently in its Phase 2 study.

Immunovant announced plans for a Phase 3 trial in myasthenia gravis (MG) as well as for other clinical trial plans for 2022,through its quarterly reports revealed on February this year. The Phase 3 in MG is planned to be initiated in the first half of 2022,and two additional pivotal clinical trials are expected in 2022. Moreover,with the addition of two new indication programs,HL161 is planned to be developed in five autoimmune diseases in the US and Europe.

HanAll Biopharma plans to initiate Phase 3 clinical trial in MG in collaboration with Immunovant in Japan,during the second half of the year.

HL036 (INN: tanfanercept): A novel,topical anti-TNF biologic therapy for dry eye disease jointly developed by HanAll Biopharma and Daewoong Pharmaceutical,tanfanercept aims to treat inflammatory eye diseases by inhibiting TNF,which is critical in ocular inflammation.

November 2021,the first patient first dose in the second Phase 3 clinical trial (study name: VELOS-3) has started in the US and the trial is currently progressing. The VELOS-3 clinical trial aims to replicate the efficacy seen in VELOS-2 (the first Phase 3 trial),and is proceeding at nine clinical sites in the US with patients who have moderate to severe dry eye disease.

HanAll's partner for Chinese market Harbour BioMed is currently conducting a pivotal Phase 3 trial of tanfanercept (also referred to as HBM9036) for dry eye disease and is progressing towards BLA submission.

HL187/ HL186:Novel immuno-oncology antibodies that respectively target TIM-3 and TIGIT,being developed in collaboration with Daewoong Pharmaceutical.

HL187 has an enhanced mechanism of action that reinforces the effector function of the antibody,which activates the immune cells to fight cancer by inhibiting the action of regulatory T cells.

Last year HL187 was nominated as participant of government-led R&D support program,by Korea Drug Development Fund (KDDF),and is proceeding toxicity study. HanAll plans to initiate Phase 1 clinical trial in 2023.

HL186 targeting TIM-3,is currently under its pre-clinical study.
