South Korea has emerged as a leader in developing innovative CAR T-cell therapies to treat cancer. Chimeric antigen receptor (CAR) T-cell therapy is a type of immunotherapy that uses engineered T-cells to target and destroy cancer cells. In CAR T-cell therapy, a patient’s T-cells are collected from their blood and modified in the lab so that they specifically target molecules found on the surface of cancer cells. Once infused back into the patient’s bloodstream, these engineered CAR T-cells can multiply in number and effectively eliminate the cancer.
South Korean researchers have made important breakthroughs in optimizing different components of CAR T-cell therapy. This includes developing new CAR constructs that can recognize novel tumor antigens with high specificity and sensitivity. They have also engineered safer viral and non-viral vectors to genetically modify T-cells with precision. Using cutting-edge bioengineering approaches, South Korean scientists are able to mass produce large numbers of potent CAR T-cells with consistent quality and purity for clinical use.
Another focus area has been developing strategies to overcome challenges like tumor immune escape and limited persistence of CAR T-cells in vivo. Researchers are engineering CAR T-cells to secrete cytokines or co-express markers that boost their anti-tumor functions. Advances in cell processing techniques allow generating CAR T-cells with memory-like properties for durable anti-tumor responses. Overall, these advancements have enabled South Korean researchers to rapidly translate innovative CAR T-cell therapy candidates into clinical trials.
Expanding South Korea Car-T Cell Therapy
South Korean hospitals and biotechs are actively conducting clinical trials to evaluate the safety and efficacy of proprietary CAR T-cell therapies. As of 2021, over 25 CAR T-cell therapy trials were ongoing across major cancer centers in South Korea. The most common cancers being targeted included blood cancers like lymphoma and multiple myeloma as well as solid tumors of the lung, breast and gastrointestinal tract.
One leading biotech, Celltrion, has dosed over 150 patients with its anti-CD19 CAR T-cell therapy, CART19-T, across three clinical trials. Interim data has shown high rates of complete remission in relapsed/refractory B-cell non-Hodgkin’s lymphoma and chronic lymphocytic leukemia patients. The therapy has also demonstrated a favorable safety profile with no serious treatment related toxicities. Based on positive results, CART19-T received SK FDA approval in 2021, becoming one of the first CAR T therapies to gain global regulatory clearance.
Other notable CAR T-cell therapy trials include GC Pharma’s anti-CD20 CAR-T (GB401), in Phase 1b for non-Hodgkin’s lymphoma. Bukwang Pharmaceuticals is evaluating its mesothelin-targeted CAR-T (BW1929) in Phase 1 trials for mesothelioma and cancers of the lung and ovary. Also in early stage testing is Anthropic’s Plug&Play CAR-T platform which allows rapidly modifying a patient’s T-cells with different CARs recognizing various cancer-specific targets. These trials continue advancing CAR T-cell immunotherapy.
Manufacturing Capabilities
Given the complex multistep process involved, manufacturing cell therapies like CAR T-cells requires specialized infrastructure and expertise. South Korea has emerged as a leading cell therapy manufacturing hub, hosting state-of-the-art commercial-scale cGMP facilities. These are either operated by global CDMOs or owned by domestic biotechs for vertical integration.
Notable cGMP production facilities include CG OncoTherapy (a subsidiary of CJ HealthCare) that can generate over 1000 CAR-T doses annually using CliniMACS Prodigy (Miltenyi Biotec). GC Cell (part of GC Pharma) has a 1000L bioreactor plant approved by the MFDS and EMA. Novatech, a subsidiary of Biovex, operates a facility compliant with FDA, EMA and PMDA regulations with multi-product cGMP cleanrooms.
South Korean manufacturers continue innovating processes to optimize cell therapy production. Automation allows standardized, closed production with minimized human errors and contamination risks. Novel manufacturing techniques can shorten processing time, improve cell viability and recovery yields. The strong contract manufacturing base establishes South Korea as a global leader for commercial-scale CAR T-cell supply to meet increasing demand from local and overseas.
Government Support For Innovation
The South Korean government has proactively supported advancements in cell and gene therapy technologies. Since 2015, the Ministry of Health and Welfare has invested over $450 million in related research projects through the Ministry’s Healthcare Technology R&D program. Leading research institutions like the Korea Institute of Science and Technology, Yonsei University and Sungkyunkwan University host advanced facilities to support academic and industrial cell therapy research.
Financial incentives like tax credits are offered to domestic biotechs developing innovative new therapies. To accelerate patient access, the South Korean FDA (MFDS) operates a fast-track conditional approval pathway for advanced therapies with unmet need. Cell therapy and regenerative medicine associations work collaboratively with the government to establish best practices and quality standards. Overall, progressive government policies continue fostering a conducive ecosystem for the growth of South Korea’s cell and gene therapy.
The developments highlight South Korea’s emergence at the forefront of CAR T-cell therapy innovation. Advanced clinical research, robust manufacturing capabilities and government support are cementing its leadership position in cell and gene therapy globally. With ongoing advancements, South Korean researchers and biotechs will continue playing a vital role in bringing life.
