THIRD QUARTER 2022 BUSINESS UPDATE

Pipeline Development Highlights

A comprehensive update on HanAll's pipeline development includes an overview of HanAll's research and a list of compounds in development with targeted indication and the phase of development.

Autoimmune Diseases Programs

Batoclimab (Project Code: HL161BKN)

A novel,fully human monoclonal antibody targeting the FcRn,with the potential to address multiple IgG-mediated autoimmune diseases. Batoclimab is designed to selectively bind to and inhibit FcRn,thus blocking the recycling of IgG antibodies.

HanAll's licensed partner,Immunovant,announced its plans to expand the indication of batoclimab to Chronic inflammatory demyelinating polyneuropathy (CIDP),and Graves' disease (GD). A Phase 2b study on CIDP to evaluate batoclimab is planned to be initiated by the end of this year,and a Phase 2 trial on GD is expected to start in early 2023.

HanAll Biopharma received approval from the Pharmaceuticals and Medical Devices Agency to initiate the Phase 3 study for batoclimab in MG in September 2022. The Phase 3 study to evaluate the safety and efficacy of batoclimab is planned to be initiated in Q4 of 2022.

Harbour BioMed,another licensed partner of HanAll who is developing batoclimab in China,signed a sub-licensing deal with CSPC NBP Pharmaceutical Co.,Ltd. in October. Under the agreement,CSPC will be granted the rights to develop and commercialize batoclimab in Greater China.

HL161ANS

A second novel,fully human,monoclonal antibody molecule inhibiting FcRn-mediated recycling of IgG,designed to deliver maximum lgG reduction while minimizing interference with albumin binding.

Immunovant announced that it will add a new FcRn inhibitor HL161ANS (Immunovant code name: IMVT-1402),discovered and developed by HanAll,to its pipeline. HL161ANS has been observed to have minimal or no impact on levels of albumin and LDL in animal studies. Immunovant plans to develop HL161ANS in a wide range of therapeutic areas including rheumatology and hematology,with a Phase 1 study expected to initiate in early 2023. The previously announced programs studying batoclimab in Myasthenia gravis (MG),Thyroid eye disease (TED),Chronic inflammatory demyelinatingpolyneuropathy (CIDP),and Graves' disease (GD) will be continued at full speed.

Eye Disease Programs

Tanfanercept (Project Code: HL036)

A novel,topical anti-TNF alpha biologic therapy for eye diseases including dry eye disease (DED) by inhibiting TNF alpha,which is critical in ocular inflammation.

HanAll Biopharma and Daewoong Pharmaceutical are continuing to conduct the second Phase 3 VELOS-3 study (NCT05109702) in patients with moderate to severe DED to examine the safety and efficacy of tanfanercept,at nine clinical sites located in the U.S. The study enrollment is completed. The topline results from VELOS-3 study are expected in the first half of 2023.

Results from the previous Phase 3 VELOS-2 study (NCT03846453) in DED have been presented at the World Cornea Congress VIII on Thursday,September 29,2022 at 10:30 am CDT in Chicago by Dr. Joseph Tauber,MD.

Harbour BioMed,HanAll's licensed partner in China,announced in early October that they decided to close their Phase 3 study without enrolling new patients to the study. As a result of its observed insufficient efficacy trend,the Independent Data Monitoring Committee recommended to terminate the trial according to the study protocol. The study in China is different from US study (VELOS-3) in key inclusion criteria,primary endpoint and patient demographics reflecting different medical practices and regulatory requirements. HanAll is in discussion with Harbour BioMed regarding the next steps.

Cancer Programs

HL187/ HL186

Novel monoclonal antibodies that respectively target TIM-3 and TIGIT,for the treatment of cancer developed in collaboration with Daewoong Pharmaceutical Co.

HanAll is continuing with the pre-clinical development of HL187 and plans to submit IND for phase 1 in 2023. HL186 is currently in the discovery phase.
