SEOUL, South Korea (april 29, 2025) – Lucas Bio announced today that its joint research project with Samsung Seoul Hospital has been selected for a national initiative focused on overcoming pediatric diseases through clinical trials. The project aims to develop a virus-specific memory T-cell therapy (LB-DTK-BKV) for treating intractable BK virus-associated hemorrhagic cystitis in children following hematopoietic stem cell transplantation.
Addressing a Critical Unmet Need
BK virus reactivation poses a significant threat to children with weakened immune systems after stem cell transplants, frequently enough leading to hemorrhagic cystitis, a condition characterized by bladder inflammation and bleeding. currently, effective treatments for this complication are lacking. Lucas Bio hopes its new therapy will fill this void.
LB-DTK-BKV: A Family-Centered Approach
The LB-DTK-BKV treatment leverages Lucas Bio’s LB-DTK platform, allowing for management using blood from hematopoietic cell transplant donors or even parents. This “life-sharing-based treatment model” integrates the patient’s family into the therapeutic process.
Multi-Antigen Targeting with LB-DTK Platform
The LB-DTK platform is an immune cell therapy technology that utilizes peripheral blood to produce multi-antigen-specific cells (CTLs). These cells are designed to target various viral antigens together.
Expanding the Arsenal: Multi-Virus Treatment in Development
Lucas Bio is also developing LB-DTK-MV, a multi-virus treatment targeting giant cell virus (CMV), Epstein-Barr virus (EBV), and BK virus (BKV) simultaneously. The company received approval for a Phase 1/2 clinical trial for this treatment on April 14. This therapy aims to combat opportunistic infections in immunocompromised patients after stem cell transplantation.
Executive Perspective
Cho seok-gu, CEO of Lucas Bio, emphasized the urgent need for better treatments. “Patients with pediatric BKV are suffering from bleeding, obstruction, bladder rupture, shock, and severe pain,” Cho said. “So far, they depend only on symptom management such as narcotic analgesics and bladder cleaning. We aim to provide a more effective solution.”
Lucas Bio specializes in viral immunotherapy,possessing three cell therapeutic platform technologies based on immune cells and stem cells. The company is actively developing treatments for viral infections, cancer, and inflammatory diseases, utilizing specialized memory T-cells.
Looking Ahead: COVID-19 Treatment and Regenerative Care
Building on the LB-DTK platform, Lucas Bio’s LB-DTK-COV19 treatment has shown success in treating long-term COVID-19 infections. The company is now preparing to seek approval for advanced regenerative medicine applications.
Lucas Bio’s Novel BK Virus Treatment: Your Questions Answered
This article explores Lucas Bio’s groundbreaking research into a new treatment for BK virus (BKV) in children. we’ll dive into the specifics of their approach, the challenges they’re addressing, and the potential impact on patients.
What is Lucas Bio Developing?
Lucas Bio is developing a novel virus-specific memory T-cell therapy called LB-DTK-BKV for treating BK virus-associated hemorrhagic cystitis in children. This therapy is designed for children who have undergone hematopoietic stem cell transplantation (HSCT).
Key Takeaway: Lucas Bio is working on a new treatment specifically targeting BKV, a virus that can cause serious complications in children after stem cell transplants.
What is BK Virus and Why is it a Problem?
BK virus (BKV) is a common virus that often lies dormant in the body. However, in immunocompromised individuals, such as children who have received stem cell transplants, BKV can reactivate. This reactivation can lead to hemorrhagic cystitis, a condition causing:
Bladder inflammation
Bleeding
Pain
Difficulty urinating
Key Takeaway: BKV reactivation is a dangerous concern for children following stem cell transplantation, often leading to painful and serious bladder complications.
What is Hemorrhagic Cystitis?
Hemorrhagic cystitis is a condition characterized by inflammation and bleeding in the bladder. It is a frequent complication of BKV reactivation, especially in children after stem cell transplants. The severity can range from mild discomfort to severe bleeding, bladder clots, obstruction, and even life-threatening situations.
Key Takeaway: Hemorrhagic cystitis, triggered by BKV, can cause bladder inflammation, intense pain, and bleeding, posing a notable health risk after stem cell transplants.
What Makes Lucas Bio’s Approach Unique?
Lucas bio’s LB-DTK-BKV treatment uses a “life-sharing-based treatment model.” This means the therapy can utilize blood from:
Hematopoietic cell transplant donors
Or even parents
This approach integrates the patient’s family into the therapeutic process.
Key Takeaway: The family-centered approach allows using blood samples for treatment, integrating the family into the patient’s care.
How Does the LB-DTK Platform Work?
The LB-DTK platform is an immune cell therapy that uses peripheral blood to generate multi-antigen-specific cells, also known as CTLs (Cytotoxic T Lymphocytes). These CTLs are designed to target multiple viral antigens together, offering a complete defense against the virus.
Key Takeaway: The LB-DTK platform produces immune cells that can recognize and eliminate cells infected wiht BK virus.
What Othre Treatments Is Lucas Bio Developing?
Lucas bio is broadening its focus. They are also developing LB-DTK-MV, a multi-virus treatment. This treatment simultaneously targets:
Cytomegalovirus (CMV)
Epstein-Barr virus (EBV)
BK virus (BKV)
This multi-virus approach aims to combat opportunistic infections common in immunocompromised patients after stem cell transplants. They also have a treatment (LB-DTK-COV19) for long-term COVID-19 infections.
Key Takeaway: Furthermore, Lucas Bio is working on treatments for several other viruses and already has a treatment for long-term COVID-19 infections.
Where Are They in the Clinical Trial Process?
Lucas Bio received approval for a Phase 1/2 clinical trial for LB-DTK-MV on April 14th.
Key Takeaway: The company is actively involved in clinical trials, which are a vital step in bringing new therapies to patients.
What is the Current Standard of care for Pediatric BKV Infections?
According to the source material, the current treatments are focused on managing symptoms. Children rely on:
Narcotic analgesics for pain
Bladder cleaning procedures
Key Takeaway: The current treatment options are focused on symptom management, emphasizing the need for a more effective, targeted solution.
How Does the CEO of Lucas Bio view this new treatment?
Cho Seok-gu, CEO of Lucas Bio, stresses the urgent need for better treatments. He highlights that patients with BKV infections suffer considerably and currently lack effective solutions beyond managing their symptoms. He aims to provide a more effective and targeted solution.
Key Takeaway: The CEO emphasizes the critical need for improved treatment options to alleviate the suffering of children with BK virus infections.
What Other Areas Does Lucas bio Focus On?
Lucas Bio specializes in viral immunotherapy, utilizing three cell therapeutic platform technologies based on immune cells and stem cells. Their research focus extends to:
Viral infections
Cancer
Inflammatory diseases
They aim to develop therapies utilizing specialized memory T-cells.
Key Takeaway: Lucas Bio is a broader innovator in viral immunotherapy, investigating various severe diseases.
What Are Lucas Bio’s Future Plans?
Building on the successes of the LB-DTK platform, Lucas Bio is exploring:
Advanced regenerative medicine applications
Seeking approval for LB-DTK-COV19 for long-term COVID-19 infections
Key Takeaway: The company is looking to the future, applying their technology to a wider range of medical fields, including regenerative medicine.
