New CAR-T Cell Therapy Shows Hope for Refractory CD30+ Lymphoma Patients
Researchers at Sant Pau Research Institute, in partnership with Sant Pau Hospital and the Josep Carreras Leukaemia Research Institute, have developed a groundbreaking CAR-T cell therapy—HSP-CAR30—targeting the CD30 protein. This therapy has shown promising results in a Phase I clinical trial for patients with refractory CD30+ lymphomas, including Hodgkin lymphoma. Key Highlights: 100% overall response rate in 10 patients with relapsed or treatment-resistant CD30+ lymphoma. 50% achieved complete remission, with no signs of cancer on scans and tests. 60% of complete responders remained cancer-free after 34 months. No serious side effects were observed—only mild, manageable symptoms like low-grade cytokine release syndrome and no neurotoxicity. What Makes HSP-CAR30 Unique? Traditional CAR-T therapies for CD30+ lymphoma have struggled with limited cell persistence and high relapse rates. The HSP-CAR30 version is optimized to: Target a stable region of the CD30 protein, reducing immune evasion by tumor cells. Promote long-lasting immune memory by enhancing central memory (TCM) and stem-like memory T cells (TSCM-LIKE). Use a new manufacturing mix of IL-21, IL-7, and IL-15 to boost durable T-cell responses. Phase II Trial Update: 32 patients have now been treated in the ongoing Phase II trial. Over 55% have achieved complete remission. Data from both trials were presented at the 2024 ASH Annual Meeting. A Step Forward in Europe: This marks Europe’s first successful CAR-T30 study, potentially offering new hope to patients with limited treatment options. Backed by Strong Support: The project received funding and resources from: Josep Carreras Leukaemia Foundation La Marató de TV3 Carlos III Health Institute ‘La Caixa’ Foundation European Union and NextGen EU Blood and Tissue Bank, among others. With further study, HSP-CAR30 could redefine treatment for CD30+ lymphomas and bring renewed hope to patients who have exhausted standard options. Source: ANI
