CAMBRIDGE, Mass., ROTTERDAM, Netherlands and SHANGHAI, July 15, 2026 /PRNewswire/—
Harbour BioMed (HKEX: 02142), a global biopharmaceutical company committed to the
discovery and development of novel antibody therapeutics in immunology, oncology
and other areas, and Kelun-Biotech (6990.HK) today announced that the National Medical
Products Administration (NMPA) of China has approved the Investigational New Drug(
IND) application for HBM7575/SKB575, a long-acting bispecific antibody targeting
thymic stromal lymphopoietin (TSLP) and an undisclosed target co-developed by the
two parties,  for the treatment of asthma. Previously, the first participant has
been dosed in a Phase 1 clinical study of HBM7575/SKB575 for the treatment of atopic
dermatitis.

Asthma is a chronic respiratory condition affecting approximately 300 million people
worldwide, with prevalence continuing to rise. Despite the availability of treatment
options, many patients experience persistent symptoms, frequent exacerbations, and
reduced quality of life. Current therapies – mainly inhaled corticosteroids (ICS)
and bronchodilators – are inadequate for some patients, underscoring the urgent 
need for more effective, long-acting treatments that address the underlying disease
mechanisms.

"Building on the recent first participant dosing for HBM7575/SKB575 in atopic dermatitis,
we are thrilled to see this molecule rapidly advancing into asthma indication." 
Dr. Jingsong Wang, Founder, Chairman and CEO of Harbour BioMed, commented. "With
two major indications now cleared for clinical development, we look forward to executing
our clinical plan and exploring the full potential of this molecule to redefine 
treatment paradigms for chronic immune-mediated conditions."

**About HBM7575/SKB575**

HBM7575/SKB575 is a long-acting bispecific antibody targeting TSLP and an undisclosed
antigen, with a dual mechanism of action. On one hand, by blocking the interaction
between TSLP and its receptor, it inhibits TSLP-mediated signaling pathways and 
the activation of Th2 immune cells. On the other hand, binding to and blocking the
undisclosed target generates a synergistic effect, with the potential to achieve
broader control of inflammation compared to single-target approaches. HBM7575/SKB575
has been engineered to allow for longer dosing intervals and a convenient subcutaneous
route of administration. Based on preclinical half-life data, the anticipated human
half-life is expected to support dosing intervals of more than three months, positioning
it as a potential best-in-class therapy.

According to the collaboration agreement between Harbour BioMed and Kelun-Biotech,
HBM7575/SKB575 is led by Kelun-Biotech in its design, global development and commercialization,
with Harbour BioMed participating in the investment and development of this asset
and sharing the benefits as agreed.

**About Harbour BioMed**

Harbour BioMed (HKEX: 02142) is a global biopharmaceutical company committed to 
the discovery and development of novel antibody therapeutics in immunology and oncology.
The company is building a robust and differentiated pipeline through internal R&
D capabilities, strategic global collaborations in co-discovery and co-development,
and selective acquisitions.

Harbour BioMed’s proprietary antibody technology platform, Harbour Mice^(®), generates
fully human monoclonal antibodies in both the conventional two heavy and two light
chain (H2L2) format and the heavy chain-only (HCAb) format. Building upon HCAb antibodies,
the HCAb-based immune cell engagers (HBICE^(®)) bispecific antibody technology enables
tumor-killing effects that traditional combination therapies cannot achieve. Additionally,
the HCAb-based bispecific immune cell antagonist (HBICA^(TM)) technology empowers
the development of innovative biologics for immunological and inflammatory diseases.
By integrating Harbour Mice^(®), HBICE^(®), and HBICA^(TM) with a single B-cell 
cloning platform, Harbour BioMed has built a highly efficient and distinctive antibody
discovery engine for developing next-generation therapeutic antibodies. For more
