Chimeric antigen receptor (CAR) technology has revolutionized immunotherapy by reprogramming the immune system to target specific cells with precision. Our alfaCAR-TTM platform harnesses this transformative power to create and assemble tailor-made CAR molecules, designed to address a broad spectrum of clinical challenges.
T lymphocytes are central to cell-mediated immunity, playing a crucial role in surveilling and eliminating cancer cells. Over the past two decades, various T‑cell immunotherapies have emerged-including tumor-infiltrating lymphocytes and T cell receptor-modified T cells-but these methods often suffer from limited efficacy and complex manufacturing. In contrast, CAR‑T therapy, with its extensive T‑cell modifications, has demonstrated robust, long-lasting performance-especially in hematologic cancers-over more than 25 years.

CAR-T cells are engineered effector T cells from natural T cells in which the T cell receptor (TCR) is replaced by a CAR to specifically identify and kill tumor cells. Important development is underway to transfer this insight to CAR-T cell applications toward both haematological malignancies and solid tumors. Our alfaCAR-T TM platform allows for the most diverse application approaches for types of cancers with difficulties, as well as for autoimmune diseases.

The treatment landscape for hematologic malignancies has significantly advanced with the advent of CAR-T cell therapy. By harnessing the power of genetically engineered T cells, CAR-T therapy offers a highly specific and personalized approach, targeting key antigens found on cancerous blood cells.
Acute Lymphoblastic Leukemia (ALL)
CAR-T cells engineered to target CD19 have achieved striking complete remission rates in patients with relapsed or refractory ALL. These therapies precisely eliminate CD19-positive leukemic cells, offering hope to patients who have not responded to conventional treatments.
Chronic Lymphocytic Leukemia (CLL)
For CLL, CAR-T therapy is designed to reinvigorate the immune response against malignant B cells. Targeting markers such as CD19, these therapies can overcome the immunosuppressive state typical of CLL, leading to measurable tumor regression and improved patient outcomes.
Lymphoma
CAR-T treatments, particularly those directed at CD19, have shown promising results in diffuse large B-cell lymphoma (DLBCL) and non-Hodgkin lymphoma (NHL). By specifically targeting lymphoma cells, these therapies induce rapid tumor shrinkage and durable remissions, even in patients with heavily pre-treated disease.
Multiple Myeloma
Targeting antigens like B-cell maturation antigen (BCMA) and CD138, CAR-T cell therapy for multiple myeloma aims to selectively destroy malignant plasma cells while sparing healthy tissues. Clinical trials have demonstrated significant reductions in tumor burden and prolonged remissions in patients who have exhausted other treatment options.
While CAR-T cell therapy has demonstrated remarkable efficacy in hematologic malignancies, its application to solid tumors faces distinct challenges attributed to the complex tumor microenvironment and antigen heterogeneity. Nonetheless, ongoing advancements in CAR-T engineering are progressively surmounting these obstacles, thereby enhancing the therapeutic potential of CAR-T cells for treating aggressive solid tumors. By targeting specific tumor-associated antigens, CAR-T therapy is establishing a promising pathway for effective treatment of melanoma, breast cancer, sarcoma, and other solid malignancies.
Melanoma
In melanoma, CAR-T cells are customized to target melanoma-associated antigens, such as MART-1 and gp100. Innovative strategies to enhance T cell infiltration and overcome the immunosuppressive tumor microenvironment are crucial for achieving effective responses in this aggressive skin cancer.
Breast Cancer
CAR-T therapies in breast cancer are focused on antigens like HER2 and MUC1. These approaches are designed to address challenges such as tumor heterogeneity and off-tumor toxicity by fine-tuning antigen recognition and incorporating mechanisms to boost T cell persistence and function within the tumor milieu.
Sarcoma
Sarcomas, a diverse group of tumors, present unique therapeutic challenges due to their heterogeneous antigen expression. CAR-T cells engineered to target specific sarcoma-associated markers are under investigation, with strategies in place to improve trafficking, penetration, and sustained cytotoxic activity against these resistant tumors.
While CAR-T cell therapy has made tremendous strides in hematologic malignancies and solid tumors, its potential reaches far beyond these domains. Recent advancements in CAR-T engineering have led to exciting applications in areas like autoimmune diseases, virus-associated cancers, and even multi-antigen targeting strategies.
