First-of-Its-Kind Success in Mismatched Donor Stem Cell Transplantation: Engraftment Under Mild Immune Suppression with Minimal Graft-versus-Host Disease
NEW YORK, NY / ACCESSWIRE / November 21, 2024 / Cell Source, Inc. (OTCQB:CLCS) ("Cell Source", or the "Company"), a pioneer in Veto Cell-based immunotherapy, today shared positive interim results from its Phase 1/2 First-in-Human clinical trial conducted at The University of Texas MD Anderson Cancer Center. The trial has treated 15 patients using Cell Source's proprietary Veto Cell technology in stem cell transplants for malignant and non-malignant hematologic diseases. These early results indicate both safety and efficacy, marking a promising advance in stem cell transplant outcomes.
"Our Veto Cell platform aims to overcome two significant challenges in stem cell therapy: preventing severe graft-versus-host disease (GvHD) while reducing treatment toxicity. With this safer, more patient-friendly approach, we are closer to making transformative treatments accessible for individuals with a variety of hematologic conditions, ranging from leukemia and lymphoma to sickle cell disease," said Dr. Dennis Brown, Chairman of Cell Source, Inc.
Breakthrough Results for Safer and Effective Transplants
Previously presented at the American Society for Hematology (ASH) Annual Meeting, the interim study results highlight:
Consistent engraftment without severe GvHD: Achieved at 42 days post- transplant with T-cell-depleted, haploidentical stem cell transplants under reduced intensity conditioning (RIC).
No toxicity linked to Veto Cells: No patients experienced adverse effects directly associated with Veto Cells.
Enhanced protocol: A mild conditioning regimen, combined with Rituximab to prevent antibody-related complications, makes transplants safer and suitable for a broader range of patients.
These findings underscore the potential of Veto Cells to increase access to life-saving allogeneic transplants for cancer patients and individuals with non-malignant blood disorders, supporting the strategic advancement of Cell Source's technology.
Comparable Successes Demonstrate Market Potential
The cell therapy and immunotherapy market has seen robust investor interest, with several start-up companies achieving multibillion-dollar valuations after clinical success. For example, Kite Pharma and Juno Therapeutics were acquired for $12 billion and $9 billion, respectively, following successful clinical outcomes and regulatory approvals in similar areas of cellular therapy. These precedents highlight the significant financial upside for novel treatments that achieve distinctive clinical efficacy and regulatory milestones.
With Cell Source's Veto Cell platform showing early promise in achieving safer and thus more effective stem cell transplants without severe GvHD, the Company is strategically positioned to capitalize on this expanding market. The total addressable market (TAM) for hematological therapeutics, including both cancer and nonmalignant diseases, is estimated to be in excess of $100 billion, underscoring the vast commercial potential for Veto Cells to gain market traction as the platform advances through clinical trials.
Pathway to Market and Competitive Edge
Cell Source's Veto Cell technology offers a unique advantage by combining reduced immune suppression with avoidance to GvHD, making it an attractive alternative to current stem cell transplant methods. The Company's Veto Cell platform is also being developed for organ transplant applications, potentially allowing for partially mismatched donors as well as reducing or possibly even eliminating reliance on lifelong immunosuppression post-transplant.
Expanding the Investor Base and Future Updates
As Cell Source advances its clinical program, the Company invites investors to explore the potential of its Veto Cell technology through our Investor Resource Center, where shareholders and prospective investors can access comprehensive information on financials, SEC filings, and the latest corporate updates. Cell Source anticipates additional milestones in 2024 and looks forward to providing further updates.
About Cell Source, Inc.
Cell Source, Inc. (OTCQB:CLCS) is the worldwide, exclusive innovator of Veto Cell-based cellular therapy and immunotherapy platform technologies designed to provide safer and more accessible stem cell (e.g. bone marrow)transplantation and improve the treatment of blood cancers such as leukemia, lymphoma and multiple myeloma. The company licenses the technology from The Weizmann Institute of Science in Israel and sponsors both research and clinical development at The University of Texas MD Anderson Cancer Center. In addition, its Veto Cell platform is being developed to reverse sickle cell disease and other non-malignant genetic blood disorders and to durably treat autoimmune diseases such as type 1 diabetes. The Company is also developing a Veto Cell CAR-T platform which could potentially enable CAR-T therapy to be used in donor-derived (allogeneic) settings with increased safety, efficacy, and persistence. Cell Source's Veto Cell technologies are also being developed to facilitate safer, donor mismatched organ transplants (e.g., kidney and liver) and also avoid the current need for life-long daily immune system suppression.
The Company is focused on transitioning this allogeneic Veto Cell platform into additional clinical trials in order to develop safe and curative cell therapy treatments (such as stem cell transplants) from mismatched donors as well as safe, durable, and efficacious "off- the-shelf" immunotherapy and immuno-oncology products.
