Core Scientific Focus and Platforms

The company’s research and development strategy is built around two proprietary technology platforms for designing fusion protein-based immunotherapies:

• TOBI™ platform (Tissue factOr-Based fusIon): Described as the company’s legacy platform, TOBI is used to construct fusion molecules that can modulate immune responses. The company’s lead product candidate, HCW9302, was developed using this platform.
• TRBC platform (T-Cell Receptor β-Chain Constant Region platform): This newer platform is not based on Tissue Factor and is characterized as a versatile scaffold for creating multiple classes of immunotherapeutic compounds. According to company disclosures, the TRBC platform can construct immunotherapeutics that both activate and target immune responses and are equipped with receptors that specifically target cancerous or infected cells.

HCW Biologics reports that it has constructed over 50 molecules using the TRBC platform. These molecules are organized into three classes of compounds:

• Class I: Multi-Functional Immune Cell Stimulators
• Class II: Second-Generation Immune Checkpoint Inhibitors
• Class III: Multi-Specific Targeting Fusions and Enhanced Immune Cell Engagers

These classes are being developed for a range of disease areas, including oncology, autoimmune diseases, and conditions that affect quality of life.

Lead Product Candidate: HCW9302

HCW9302 is described by the company as its lead product candidate for clinical development in autoimmune diseases and other proinflammatory conditions. Key characteristics disclosed by HCW Biologics include:

• HCW9302 is a subcutaneously injectable, first-in-kind interleukin-2 (IL-2) fusion molecule constructed using the TOBI platform.
• IL-2 is identified as the cytokine responsible for maintaining the proper numbers and functions of regulatory T (Treg) cells in humans and other vertebrates.
• Treg cells are described as controlling excessive inflammation caused by other immune cells, which the company notes is the etiology of autoimmune diseases.

HCW Biologics has initiated a company-sponsored, multi-center Phase 1, first-in-human clinical trial (NCT07049328) to evaluate HCW9302 in patients with an autoimmune disease, specifically alopecia areata. The company has disclosed that the first patient was dosed in this trial at The Ohio State University Wexner Medical Center. The study is a dose-escalation trial designed to treat up to 30 patients with alopecia areata, with primary objectives to evaluate safety and determine a recommended dose level for later-phase clinical studies. Secondary objectives include assessing disease responses and the effects of HCW9302 on immune cells, particularly Treg cells.

In its public statements, the company indicates that HCW9302 is being developed for alopecia areata and potentially other autoimmune and inflammatory dermatological conditions, as well as other inflammatory conditions such as graft versus host disease and certain neurodegenerative diseases, based on preclinical data. These forward-looking plans are described by the company as subject to clinical results and other factors.

TRBC-Based Programs: Immune Checkpoint Inhibitors and T-Cell Engagers

Beyond HCW9302, HCW Biologics highlights several TRBC-based programs at the preclinical and IND-enabling stages:

• HCW11-040 – Second-Generation Immune Checkpoint Inhibitor
  HCW11-040 is described as the company’s lead product candidate in its immune checkpoint inhibitor (ICI) program and as a franchise immunotherapeutic for internal clinical development. It is characterized as a tetra-valent, pembrolizumab-based multi-functional fusion protein that includes IL-15 and IL-7 domains and a transforming growth factor β (TGF-β) trap. In preclinical studies reported by the company, HCW11-040 has demonstrated PD-1/PD-L1 blocking activity equivalent to pembrolizumab and has shown the ability to expand progenitor exhausted T (TPEX) cells, expand and activate human peripheral blood lymphocytes and memory T cells, and promote anti-tumor activity in organoid models, while avoiding evidence of excessive inflammatory responses after subcutaneous administration.
• HCW11-018b – T-Cell Engager (TCE) Program
  HCW11-018b is identified as the lead T-cell engager product candidate in the company’s second-generation TCE program based on the TRBC platform. Company disclosures describe HCW11-018b as a tetra-valent construct with broad coverage for human solid tumor indications by targeting tissue factor, high potency and precision in xenograft and patient-derived xenograft models, activation of tumor-infiltrated exhausted T cells, a favorable tolerability profile in non-human primates at dosing levels higher than efficacious levels, long serum half-life, and a streamlined GMP manufacturing process similar to therapeutic monoclonal antibodies. Subcutaneous administration is highlighted as a potential benefit for safety and patient quality of life.
• HCW11-006 – Multi-Functional Immune Cell Stimulator
  HCW11-006 is referenced as a Class I TRBC compound and a novel cytokine fusion molecule. It is the subject of IND-enabling studies and is included in an amended and restated license, research and co-development agreement with Beijing Trimmune Biotech Co., Ltd. Under that agreement, HCW Biologics has granted Trimmune an exclusive license to HCW11-006 for in vivo applications, with provisions for an upfront license fee split between cash and transferable equity, an option for Trimmune to license HCW9302 for in vivo applications in China or Asia, and a retained option for HCW Biologics to recapture rights in specified territories after Phase 1, subject to the agreement’s terms.

The company has indicated that three TRBC-based molecules have been selected as lead product candidates for clinical development programs in cancer and age-related diseases based on promising preclinical data, and that IND-enabling work is underway for these candidates.

Chronic Inflammation, Inflammaging, and Target Indications

HCW Biologics repeatedly emphasizes chronic inflammation and inflammaging as central to its scientific rationale. The company notes that chronic inflammation, including age-associated inflammatory processes, is believed to be a significant contributing factor to senescence-associated diseases and conditions that diminish healthspan. Examples cited by the company include many types of cancer, autoimmune diseases, neurodegenerative diseases, and other indications that affect quality of life but may not be life-threatening. Its immunotherapeutic candidates are being developed for a wide range of disease indications in oncology, autoimmune disease, and quality-of-life conditions, with the goal of modulating immune pathways that drive these chronic inflammatory states.

Licensing and Collaboration Activities

HCW Biologics reports that it has two licensing programs in which it has licensed exclusive rights for some of its proprietary molecules. One notable relationship is with Wugen, Inc., for which HCW Biologics has granted an exclusive license to certain molecules and has historically recognized revenue from an upfront license fee and product sales of clinical material. The company also holds a minority equity interest in Wugen as part of the license fee structure and has publicly commented on Wugen’s financing activities.

In addition, the company has entered into an amended and restated license, research and co-development agreement with Beijing Trimmune Biotech Co., Ltd. relating to HCW11-006 and an option to license HCW9302 for in vivo applications in specified territories, with Trimmune responsible for research, development, manufacturing, clinical, regulatory, and commercialization costs in its territory, subject to closing conditions and potential reversion of rights if those conditions are not met within a defined period.
