Cellectis Unveils Promising Pre-Clinical Data on CAR T-cell Therapy
Today, Cellectis, a pioneering biotechnology company, showcased exciting scientific advancements in the field of cancer treatment. As a clinical-stage firm utilizing its unique gene-editing platform, Cellectis is committed to developing innovative cell and gene therapies that aim to save lives. This latest development focuses on MUC1 CAR T-cells, which have shown potential as a treatment option for triple-negative breast cancer (TNBC), a particularly aggressive form of breast cancer.
Understanding Triple-Negative Breast Cancer
Breast cancer is remarkably prevalent among women worldwide, with triple-negative breast cancer being recognized as its most challenging variant. TNBC is known for its high rate of metastasis and disappointing survival statistics, leaving many patients with few treatment alternatives. While some new targeted therapies are on the horizon, traditional methods like chemotherapy, surgery, and radiation therapy still dominate, and unfortunately, their efficacy is often limited.
Innovative CAR T-cell Therapy Approach
Cellectis is exploring Chimeric Antigen Receptor (CAR) T-cell therapies as a promising solution for advanced-stage TNBC patients. Researchers have identified that the tumor-associated MUC1 antigen is overexpressed in a significant proportion of TNBC patients, providing a compelling target for effective treatment.
Cellectis' Multi-Layered CAR T-cell Engineering
The recent study published in Science Advances presents Cellectis' sophisticated engineering approach to CAR T-cells utilizing TALEN technology and synthetic biology. This multi-armor strategy enhances CAR T-cells with synergistic capabilities, allowing them to overcome the immunosuppressive tumor microenvironment typically found in solid tumors. In pre-clinical mouse models, data showed that modifying MUC1 CAR T-cells with attributes such as PD1KO, TGFBR2KO, and the release of tumor-specific IL12 fosters enhanced cytotoxic activity against TNBC.
Enhanced Efficacy and Safety
As noted by Dr. Piril Erler, a scientist at Cellectis, the complexity of solid tumors is a significant barrier to the effectiveness of conventional CAR T-cell therapies. The recent findings demonstrate that using TALEN-mediated multiplex editing allows CAR T-cells to mount a robust anti-tumor response effectively. Additionally, the innovative intratumoral injection method enables the use of lower doses while treating both the primary and distant tumors, offering a strategic advantage.
Potential of Local Administration
Cellectis' research highlights an intriguing discovery: the multi-armored MUC1 CAR T-cells effectively reduced large local and distant tumors using minimal doses. This finding not only underscores the power of antigen recognition but also indicates a possible strategy for addressing metastasis through localized therapy.
About Cellectis
Cellectis has established itself as a leader in gene editing and cellular therapies, utilizing its proprietary TALEN technology. By promoting an allogeneic approach for CAR T immunotherapies, the company strives to deliver ready-to-use, gene-edited CAR T-cells that respond swiftly to the challenges of cancer treatment. With 25 years of experience, Cellectis continues to devise groundbreaking product candidates aimed at unmet medical needs in oncology.
Investment and Future Outlook
Cellectis' stock is traded on both the Nasdaq Global Market under the ticker symbol CLLS and Euronext Growth under the ticker ALCLS. With ongoing research and development efforts, the company is well positioned to drive future innovations in the treatment of various malignancies.
