HCW Biologics Discovers that HCW11-040 Prevents Bronchopulmonary Dysplasia (BPD) During IND-Enabling Studies
Rhea-AI Summary
HCW Biologics (NASDAQ: HCWB) reported that HCW11-040, a pembrolizumab-based fusion immunotherapeutic, prevented bronchopulmonary dysplasia (BPD) in a stringent animal model during IND-enabling studies. A single subcutaneous dose was effective.
The company expects to complete IND-enabling studies in 2H 2027 and then file an IND for high-risk infants. BPD affects an estimated 10,000–15,000 U.S. premature infants annually, and HCW Biologics believes this indication could align with the reauthorized Rare Pediatric Disease priority review voucher program, funded through September 2029.
Positive
- HCW11-040 prevented BPD in a stringent, clinically relevant animal model
- Single subcutaneous dose of HCW11-040 was effective in preclinical BPD prevention
- Company targets BPD, with 10,000–15,000 U.S. cases annually
- Potential alignment with Rare Pediatric Disease priority review voucher program funded through 2029
- IND-enabling studies are underway with completion expected in second half of 2027
Negative
- HCW11-040 remains in IND-enabling stage; human clinical trials have not yet begun
- No known cure for BPD, indicating a challenging disease landscape despite new approaches
- Clinical evaluation of HCW11-040 for BPD is unlikely before completion of IND-enabling work in 2027

24h Move is the share-price change in the day after each event; other market factors may also have contributed.
Positive scientific and pipeline updates have often coincided with strong upside moves, while financing and governance items have tended to pressure the stock.
Over the last few months, HCW Biologics has mixed financing and governance pressures with notable scientific progress. A March 2026 Science Advances publication for HCW9206 coincided with a 60.92% gain, while an April update on T‑cell engager HCW11-018b saw a 16.88% rise. Conversely, licensing HCW11-006 with a $7.0M upfront package led to a 6.33% decline, and 2025 results highlighting going-concern doubts saw a 16.67% drop. Today’s preclinical BPD discovery fits the pattern of value-driving scientific news against a challenged equity base.

HCW11-040 is a pembrolizumab-based fusion immunotherapeutic that activates immune cells and eliminates high-oxygen induced senescent cells
BPD is a rare pediatric disease affecting underweight premature infants which the Company believes aligns with newly reauthorized rare pediatric disease and review voucher programs
BPD causes abnormal lung development in premature infants that leads to long-term health problems that persist into adulthood as well as neurodevelopmental delays
MIRAMAR, Fla., May 14, 2026 (GLOBE NEWSWIRE) -- HCW Biologics Inc. (the “Company” or “HCW Biologics”), (NASDAQ: HCWB), a U.S.-based clinical-stage biopharmaceutical company focused on developing novel fusion immunotherapeutics to treat autoimmune diseases, cancer, and senescence-associated dysplasia, announced today that its scientists and academic collaborators at Queen’s University at Kingston, Ontario discover that HCW11-040, a second-generation, pembrolizumab-based fusion immunotherapeutic, prevents bronchopulmonary dysplasia (“BPD”) during IND-Enabling studies. The Company expects to complete IND-Enabling studies in the second half of 2027 and intends to immediately file an IND application to evaluate HCW11-040 in patients at a high risk of developing BPD.
BPD in neonates causes long-term health impacts primarily related to chronic lung disease, including reduced lung function, asthma-like symptoms, and higher susceptibility to infections, which can persist into adulthood. Survivors may also face neurodevelopmental delays, impaired exercise tolerance, and in severe cases, pulmonary hypertension, necessitating specialized, multidisciplinary care. There is no known cure for BPD, and it is a high-impact unmet medical need since the premature infants who have BPD have diminished life-long healthspan. In the United States, there are 10,000 – 15,000 cases annually. It is the most common serious complication of prematurity, characterized by lung damage from ventilation and oxygen therapy. Despite advancements in care, the incidence of BPD has remained relatively stable over the last few decades.
On February 3, 2026, President Donald Trump reauthorized the Mikaela Naylon Give Kids a Chance Act and revived the rare pediatric disease (“RPD”) priority review voucher program (“PRV”). The RPD program will now be funded through September 2029. The United States Food and Drug Administration grants RPD Designation for rare pediatric disorders to encourage development of treatments for diseases which are life-threatening conditions with no currently approved, specific drug treatments. The Company believes by focusing on the BPD indication, we can align with the Rare Pediatric Disease PRV program.
HCW11-040 is a novel fusion immunotherapeutic that is designed to block the checkpoint receptors and engage the costimulatory receptors, analogous to taking the foot off the brake and simultaneously hitting the gas. It is designed to activate exhausted immune cells. While conducting IND-enabling studies with collaborators at Queen’s University at Kingston, Ontario, the Company discovered that a single-dose of HCW11-040 administered subcutaneously also effectively prevented the development of BPD in a clinically relevant and highly stringent animal model.
Dr. Hing C. Wong, the Company’s Founder and Chief Executive Officer, stated, “We created HCW11-040 with a generic form of Keytruda®, the clear leader in immune checkpoint inhibitors. We consider our immunotherapeutic as second generation, since in our preclinical studies, it outperformed pembrolizumab as a monotherapy in immune-cell activation and expansion, enhancement of immune cell infiltration into the tumors, and immune cell cytotoxicity against cancer cells.”
Dr. Wong continued, “At the outset on the road to our discovery of the potential for HCW11-040 to treat BPD, our hypothesis was that immune checkpoint inhibitors have the potential to treat diseases beyond cancer, since they have also recently been identified as effective senomorphic drugs for senescent cell removal to treat age-related or stressor-induced related diseases. We are very excited to discover that HCW11-040 could indeed be used to prevent senescence-associated dysplasia such as BPD. We will vigorously pursue the clinical development of HCW11-040 for this indication.”
